Reducing cognitive impairment from SCLC brain metastases

Article Type
Changed

For patients with up to 10 brain metastases from small cell lung cancer (SCLC), stereotactic radiosurgery was associated with less cognitive impairment than whole-brain radiation therapy (WBRT) without compromising overall survival, results of the randomized ENCEPHALON (ARO 2018-9) trial suggest.

Among 56 patients with one to 10 SCLC brain metastases, 24% of those who received WBRT demonstrated significant declines in memory function 3 months after treatment, compared with 7% of patients whose metastases were treated with stereotactic radiosurgery alone. Preliminary data showed no significant differences in overall survival between the treatment groups at 6 months of follow-up, Denise Bernhardt, MD, from the Technical University of Munich, reported at the American Society of Radiation Oncology (ASTRO) annual meeting.

“We propose stereotactic radiosurgery should be an option for patients with up to 10 brain metastases in small cell lung cancer,” Dr. Bernhardt said during her presentation.

Vinai Gondi, MD, who was not involved in the study, said that the primary results from the trial – while limited by the study’s small size and missing data – are notable.

Patients with brain metastases from most cancer types typically receive stereotactic radiosurgery but WBRT has remained the standard of care to control brain metastases among patients with SCLC.

“This is the first prospective trial of radiosurgery versus whole-brain radiotherapy for small cell lung cancer brain metastases, and it’s important to recognize how important this is,” said Dr. Gondi, director of Radiation Oncology and codirector of the Brain Tumor Center at Northwestern Medicine Cancer Center, Warrenville, Ill.

Prior trials that have asked the same question did not include SCLC because many of those patients received prophylactic cranial irradiation, Dr. Gondi explained. Prophylactic cranial irradiation, however, has been on the decline among patients with brain metastases from SCLC, following a study from Japan showing no difference in survival among those who received the therapy and those followed with observation as well as evidence demonstrating significant toxicities associated with the technique.

Now “with the declining use of prophylactic cranial irradiation, the emergence of brain metastases is increasing significantly in volume in the small cell lung cancer population,” said Dr. Gondi, who is principal investigator on a phase 3 trial exploring stereotactic radiosurgery versus WBRT in a similar patient population.

In a previous retrospective trial), Dr. Bernhardt and colleagues found that first-line stereotactic radiosurgery did not compromise survival, compared with WBRT, but patients receiving stereotactic radiosurgery did have a higher risk for intracranial failure.

In the current study, the investigators compared the neurocognitive responses in patients with brain metastases from SCLC treated with stereotactic radiosurgery or WBRT.

Enrolled patients had histologically confirmed extensive disease with up to 10 metastatic brain lesions and had not previously received either therapeutic or prophylactic brain irradiation. After stratifying patients by synchronous versus metachronous disease, 56 patients were randomly assigned to either WBRT, at a total dose of 30 Gy delivered in 10 fractions, or to stereotactic radiosurgery with 20 Gy, 18 Gy, or fractionated stereotactic radiosurgery with 30 Gy in 5 Gy fractions for lesions larger than 3 cm.

The primary endpoint was neurocognition after radiation therapy as defined by a decline from baseline of at least five points on the Hopkins Verbal Learning Test-Revised (HVLT-R) total recall subscale at 3 months. Secondary endpoints included survival outcomes, additional neurocognitive assessments of motor skills, executive function, attention, memory, and processing as well as quality-of-life measures.

The investigators expected a high rate of study dropout and planned their statistical analysis accordingly, using a method for estimating the likely values of missing data based on observed data.

Among 26 patients who eventually underwent stereotactic radiosurgery, 18 did not meet the primary endpoint and 2 (7%) demonstrated declines on the HVLT-R subscale of 5 or more points. Data for the remaining 6 patients were missing.

Among the 25 who underwent WBRT, 13 did not meet the primary endpoint and 6 (24%) demonstrated declines of at least 5 points. Data for 6 of the remaining patients were missing.

Although more patients in the WBRT arm had significant declines in neurocognitive function, the difference between the groups was not significant, due to the high proportion of study dropouts – approximately one-fourth of patients in each arm. But the analysis suggested that the neuroprotective effect of stereotactic radiosurgery was notable, Dr. Bernhardt said.

At 6 months, the team also found no significant difference in the survival probability between the treatment groups (P = .36). The median time to death was 124 days among patients who received stereotactic radiosurgery and 131 days among patients who received WBRT. 

Dr. Gondi said the data from ENCEPHALON, while promising, need to be carefully scrutinized because of the small sample sizes and the possibility for unintended bias.

ARO 2018-9 is an investigator-initiated trial funded by Accuray. Dr. Bernhardt disclosed consulting actives, fees, travel expenses, and research funding from Accuray and others. Dr. Gondi disclosed honoraria from UpToDate.

Hormone therapy less effective in menopausal women with obesity

Article Type
Changed

Women with obesity experience greater menopausal symptoms but substantially less relief from hormone therapy (HT) than women without obesity, according to a small, retrospective study presented at the annual meeting of the Menopause Society (formerly the North American Menopause Society).

More than 40% of women over age 40 in the United States have obesity, presenter Anita Pershad, MD, an ob.gyn. medical resident at Eastern Virginia Medical School, Norfolk, told attendees. Yet most of the large-scale studies investigating perimenopausal and postmenopausal hormone therapy included participants without major medical comorbidities, so little data exist on how effectively HT works in women with these comorbidities, she said

“The main takeaway of our study is that obesity may worsen a woman’s menopausal symptoms and limit the amount of relief she gets from hormone therapy,” Dr. Pershad said in an interview. “It remains unclear if hormone therapy is less effective in women with obesity overall, or if the expected efficacy can be achieved with alternative design and administration routes. A potential mechanism of action for the observed decreased effect could be due to adipose tissue acting as a heat insulator, promoting the effects of vasomotor symptoms.”

Dr. Pershad and her colleagues conducted a retrospective review of the medical records of 119 patients who presented to a menopause clinic at a Midsouth urban academic medical center between July 2018 and December 2022. Obesity was defined as having a body mass index (BMI) of 30 kg/m2 or greater.

The patients with and without obesity were similar in terms of age, duration of menopause, use of hormone therapy, and therapy acceptance, but patients with obesity were more likely to identify themselves as Black (71% vs. 40%). Women with obesity were also significantly more likely than women without obesity to report vasomotor symptoms (74% vs. 45%, P = .002), genitourinary/vulvovaginal symptoms (60% vs. 21%, P < .001), mood disturbances (11% vs. 0%, P = .18), and decreased libido (29% vs. 11%, P = .017).

There were no significant differences in comorbidities between women with and without obesity, and among women who received systemic or localized HT, the same standard dosing was used for both groups.

Women with obesity were much less likely to see a satisfying reduction in their menopausal symptoms than women without obesity (odds ratio 0.07, 95% confidence interval, 0.01-0.64; P = .006), though the subgroups for each category of HT were small. Among the 20 women receiving systemic hormone therapy, only 1 of the 12 with obesity (8.3%) reported improvement in symptoms, compared with 7 of the 8 women without obesity (88%; P = .0004). Among 33 women using localized hormone therapy, 46% of the 24 women with obesity vs. 89% of the 9 women without obesity experienced symptom improvement (P = .026).

The proportions of women reporting relief from only lifestyle modifications or from nonhormonal medications, such as SSRIs/SNRIs, trazodone, and clonidine, were not statistically different. There were 33 women who relied only on lifestyle modifications, with 31% of the 16 women with obesity and 59% of the 17 women without obesity reporting improvement in their symptoms (P = .112). Similarly, among the 33 women using nonhormonal medications, 75% of the 20 women with obesity and 77% of the 13 women without obesity experienced relief (P = .9).
 

 

 

Women with obesity are undertreated

Dr. Pershad emphasized the need to improve care and counseling for diverse patients seeking treatment for menopausal symptoms.

“More research is needed to examine how women with medical comorbidities are uniquely impacted by menopause and respond to therapies,” Dr. Pershad said in an interview. “This can be achieved by actively including more diverse patient populations in women’s health studies, burdened by the social determinants of health and medical comorbidities such as obesity.”

Mayo Clinic
Dr. Stephanie S. Faubion

Stephanie S. Faubion, MD, MBA, director for Mayo Clinic’s Center for Women’s Health, Rochester, Minn., and medical director for The Menopause Society, was not surprised by the findings, particularly given that women with obesity tend to have more hot flashes and night sweats as a result of their extra weight. However, dosage data was not adjusted for BMI in the study and data on hormone levels was unavailable, she said, so it’s difficult to determine from the data whether HT was less effective for women with obesity or whether they were underdosed.

“I think women with obesity are undertreated,” Dr. Faubion said in an interview. “My guess is people are afraid. Women with obesity also may have other comorbidities,” such as hypertension and diabetes, she said, and “the greater the number of cardiovascular risk factors, the higher risk hormone therapy is.” Providers may therefore be leery of prescribing HT or prescribing it at an appropriately high enough dose to treat menopausal symptoms.

Common practice is to start patients at the lowest dose and titrate up according to symptoms, but “if people are afraid of it, they’re going to start the lowest dose” and may not increase it, Dr. Faubion said. She noted that other nonhormonal options are available, though providers should be conscientious about selecting ones whose adverse events do not include weight gain.

Although the study focused on an understudied population within hormone therapy research, the study was limited by its small size, low overall use of hormone therapy, recall bias, and the researchers’ inability to control for other medications the participants may have been taking.

Dr. Pershad said she is continuing research to try to identify the mechanisms underlying the reduced efficacy in women with obesity.

The research did not use any external funding. Dr. Pershad had no industry disclosures, but her colleagues reported honoraria from or speaking for TherapeuticsMD, Astella Pharma, Scynexis, Pharmavite, and Pfizer. Dr. Faubion had no disclosures.

Short-course SBRT: Standard of care in prostate cancer?

Article Type

With just five fractions of stereotactic body radiation therapy (SBRT), men with low- or intermediate-risk prostate cancer can have 5-year disease control as good as that provided by conventional external-beam radiation therapy delivered at higher doses in 20-39 fractions, according to new data from the phase 3 randomized PACE-B trial.

Overall, the 5-year event-free survival rates were 95.8% among patients who received SBRT and 94.6% among those who had conventional radiation. The incidence of adverse events was also low in both groups, with no significant differences observed between the trial arms.

The similar event-free survival and toxicity profiles in both groups provide more support for SBRT, which treats prostate cancer with larger radiation fractions over a shorter time period.

“I think we can also say now with a high level of confidence that SBRT can be considered a new standard of care for low and favorable intermediate-risk prostate cancer,” said Nicholas van As, MD, MB, from the Royal Marsden NHS Foundation Trust and Institute of Cancer Research in London, who presented efficacy and safety results from the noninferiority trial at the American Society for Radiation Oncology (ASTRO) annual meeting. SBRT is more convenient for patients and more cost-effective for health care providers, Dr. Van As added.

Invited discussant Alejandro Berlin, MD, MSc, from Princess Margaret Cancer Centre and the University of Toronto, agreed “that this should be a standard of care for low and favorable intermediate-risk prostate cancer,” an option already endorsed by relevant guidelines.

But, Dr. Berlin noted, SBRT requires careful attention to technique to achieve the desired results. Further research will be needed to identify and potentially reduce variability among radiation oncology practice regarding margins, dosimetry goals, dose heterogeneity, treatment schedules, and other factors, he said.
 

An international trial

PACE-B is one of three branches of a multi-center collaboration among 37 radiation therapy centers in the United Kingdom, Ireland, and Canada.

In the trial, investigators enrolled 874 patients with T1c or T2c prostate cancer, Gleason score of 3+4 or less, prostate-specific antigen (PSA) level no higher than 20 ng/mL, MRI staging, and no prior androgen deprivation therapy. Investigators then randomly assigned them on a 1:1 basis to receive either conventional radiation (n = 441) or SBRT (n = 433).

At the start of the trial, patients who were assigned to the conventional radiation group received 78 Gy in 39 fractions over 4-8 weeks. However, after results from the CHHiP trial, which showed that a 60-Gy, 20-fraction regimen was not inferior to a 74-Gy, 37-fraction regimen, the PACE-B investigators modified the protocol to 62 Gy delivered in 20 fractions.

Patients assigned to SBRT received 36.25 Gy divided into give fractions delivered over 1-2 weeks, with 40 Gy to the clinical target volume.

The primary outcome was noninferiority of SBRT, measured as whether patients remained free of biochemical clinical failure. Biochemical clinical failure was defined as evidence that the cancer was returning, such as an increase in PSA levels or distant metastases or death from prostate cancer.

At a median follow-up of 73.1 months, 5-year event-free survival rates were 94.6% for patients who received conventional radiation therapy and 95.8% for patients who received SBRT, meeting the prespecified criteria for noninferiority of SBRT (P = .007).

Freedom from biochemical and clinical failure, the trial’s primary endpoint, “was significantly better on both arms than our original power calculation, where we expected control rates of approximately 85%,” Dr. Van As said in an ASTRO plenary session.

Toxicity rates were also low in both study arms. The rate of grade 2 or greater urogenital side effects at 5 years was 5.5% in the SBRT arm and 3.2% in the conventional therapy arm. Grade 2 or greater gastrointestinal side effects occurred in only two patients, one in each study arm.

Given the findings, “I think it’s now imperative that our surgeons discuss this data with their patients before they perform prostatectomies,” Dr. Van As said.

Neha Vapiwala, MD, president-elect of ASTRO who moderated a media briefing where Dr. Van As summarized the PACE-B data, commented that “this study was conducted very rigorously, with excellent quality assurance.”

The study also highlights that clinicians in the United States have considerable catching up to do, said Dr. Vapiwala, from the Hospital of the University of Pennsylvania, Philadelphia.

In the United States, “we are way behind our colleagues on the other side of the pond,” she said. “We are way behind in our uptake of ultra-hypofractionated radiation [such as SBRT], and I do believe that some of that comes from the lack of feeling comfortable with the techniques that are needed and the expertise that is needed.”

PACE-B was funded by Accuray. Dr. Van As disclosed research grants from the company and consulting fees from Varian. Dr. Berlin reported no conflict of interest relevant to the study. Dr. Vapiwala has disclosed a consulting or advisory role with Bayer.

Adopting high-dose radiation vs. conventional after mastectomy could be ‘game changer’

Article Type
Changed

SAN DIEGOWomen with breast cancer who underwent postmastectomy breast reconstruction benefited from shorter bursts of higher-dose radiation, compared with the standard therapy, according to a new prospective, randomized study.

Side effects and physical well-being scores were similar among 400 women who received the two treatment regimens, and outcomes were similar or slightly better in the higher-dose group, reported Rinaa Punglia, MD, MPH, an associate professor of radiation oncology at Dana-Farber Brigham Cancer Center in Boston and colleagues at the annual meeting of the American Society for Radiation Oncology. In a press statement, Dr. Punglia noted that the outcomes weren’t as impressive as researchers had hoped, but it’s positive that higher doses didn’t cause more side effects.

The use of the higher-dose approach, known as hypofractionation, “resulted in fewer treatment breaks and less financial toxicity” vs. conventional fractionation, Dr. Punglia said at a news briefing. The findings of the FABREC study “support the use of hypofractionated postmastectomy radiation for patients with basic reconstruction.”

According to Dr. Punglia, “postmastectomy radiation therapy is indicated for almost one-third of mastectomy patients and improves the lives of patients who are at an elevated risk for recurrence.” However, “the addition of radiation therapy greatly increases the risk of reconstruction complications.”

The typical radiation treatment period is 5-6 weeks in these patients, a major hardship for patients that can take them away from their families for extended periods of time. The researchers sought to understand whether another approach – hypofractionation over 3-4 weeks – is a better option. The strategy is widely used after breast-conserving surgery, she said, and has been linked to similar cancer outcomes, improved quality of life, and improved breast appearance.

From 2018 to 2021, the researchers recruited 400 patients with stage 0-III breast cancer who were treated with mastectomy and immediately underwent implant-based reconstruction (median age = 47.0, 23-79). None had tumors growing into the chest wall or skin.

The patients, spread nationwide across 16 institutions, were randomized to receive conventional fractionation (n = 201, 25 fractions, 5 days a week for 5 weeks of 200 cGy) or hypofractionation (n=199, 16 fractions, 5 days a week, for about 3 weeks of 266 cGy).

The researchers tracked 385 patients over a median follow-up of 40.4 months. There was no statistically significant difference in distant recurrence (12 in conventional fractionation arm, 11 in hypofractionation arm), death (2 in each arm), local recurrence (1 in each arm), or toxicity in the chest wall area (20 in conventional fractionation arm, 19 in hypofractionation arm). Changes in physical well-being scores, the primary endpoint, were similar after controlling for age.

“We found that younger patients randomized to hypofractionation were less bothered by side effects of treatment at 6 months relative to their counterparts who received conventional fractionation,” Dr. Punglia said.

Treatment breaks were more common in the conventional fractionation arm (7.7%, mean = 3.3 days) vs. the hypofractionation arm (2.7%, mean = 2.8 days, P = .03).

Among 51 patients who took unpaid time off work, those who underwent hypofractionation took fewer mean days off (73.7 days vs. 125.8 days for conventional fractionation, P = .046).

The study is the first of its kind to compare conventional fractionation to hypofractionation in this population in a randomized, phase III study, Dr. Punglia said.

At the news briefing, an independent expert – Lori Pierce, MD, a professor of radiation oncology at the University of Michigan – said the new study is a “game changer.”

The findings about the benefits of hypofractionation “will potentially impact thousands of women,” said Dr. Pierce, former president of the American Society of Clinical Oncology. The shorter course of radiation is more convenient for patients, she said, and reduces hardship.

“Without a doubt, these results should be discussed with all patients who have had mastectomy and implant-based reconstruction,” she said.

In an interview, Bruce G. Haffty, MD, MS, professor and chair of Radiation Oncology at Rutgers Cancer Institute of New Jersey, said the study adds to existing data suggesting that shorter courses of therapy “are probably OK.” The new findings “give people a little more confidence that [short courses are] safe in terms of well-being and toxicity.”

However, the follow-up in the trial is relatively short, he said, and longer-term research will be needed to change the standard of care in these patients. “It’ll be an evolving story over the next 5-10 years,” he said.

The study was funded by the Patient-Centered Outcomes Research Institute. Dr. Punglia has no disclosures; disclosures for other authors were not provided. Disclosure information for Dr. Pierce was not provided. Dr. Haffty is an investigator in a similar study called RT CHARM.

SABR could defer systemic therapy in oligoprogressive breast cancer

Article Type
Changed

– Stereotactic ablative body radiotherapy (SABR) appeared to delay the need for changes in systemic therapy in postmenopausal patients with oligoprogressive luminal ER-positive, HER2-negative breast cancer, according to a new phase 2 study.

In the AVATAR trial, patients with one to five metastatic lesions who’d been treated with cyclin-dependent kinase (CDK) 4/6 inhibitors and aromatase inhibitors for at least 6 months underwent SABR. Of those, 47% had event-free survival of more than 6 months, an unexpectedly high figure, reported radiation oncologist Steven David, MBBS, of Peter MacCallum Cancer Center, Melbourne, and colleagues at the annual meeting of the American Society for Radiation Oncology.

“We found surprisingly that SABR delayed a change in therapy by 10 months, which is great for patients. Also, one in three patients had a second round of SABR,” said Dr. David in an interview. “This trial provides the first prospective evidence to delay a change in therapy in this population, and this strategy is ready to go now.”

According to Dr. David, oligoprogressive luminal, ER-positive, HER2-negative, advanced breast cancer cannot be cured. However, patients can live more than 10 years in some cases, and an early treatment – CDK 4/6 inhibitors and aromatase inhibitors – is well tolerated. “Patients can lead a normal life and avoid chemo” as long as those medications keep working.

The goal of the study was to determine if SABR is helpful in these patients. The treatment, which produces highly focused radiation, “has very few side effects and does a great job in eliminating progressing metastases,” Dr. David said.

For the study, researchers recruited 32 subjects at 13 Australian sites. Participants could not have had leptomeningeal disease, previous chemotherapy for metastatic disease, or prior radiotherapy to an oligoprogressing lesion. Most metastases were to bone (n = 44, 71%), node (systemic, n = 8; 13%) and lung (n = 4; 6%).

The patients were treated with SABR, most commonly 24 Gy (n = 25; 43%) and 20 Gy (n = 10; 17%); half had one lesion treated (50%), and 25% had two lesions treated.

The median follow-up was 15.8 months. The median event-free survival was 5.2 months (95% confidence interval, 3.1-9.4 months), with events defined as progression within 6 months or in at least three lesions. Fifteen patients (47%) reached event-free survival of 6 or more months.

Elysia Donovan, MD, MSc, a radiation oncologist at McMaster University, Hamilton, Ont., said in an interview that the new study is thoughtfully designed, although it’s not definitive. “At this point we still do not know the optimal treatment regimen for oligoprogressive breast cancer. The findings of this trial are promising and exciting. However, further randomized trials are required before routine implementation in clinical practice. For now, patients should be considered in a case by case basis with multidisciplinary discussion to determine the optimal systemic therapy regimen at oligoprogression and whether SABR may provide benefit.”

Median modified progression-free survival was 10.4 months, and median progression-free survival was 5.2 months; 31% of patients received SABR for further oligoprogression, and 46% patients remained on CDK4/6 inhibitors and aromatase inhibitors for 12 months. Overall survival was 100%.

A total of 14 patients had grade 1 adverse events, 2 had grade 2 events, and none had grade 3 or higher events; 47% had no treatment-related toxicity.

The strategy “potentially has a place in other cancer types and other breast cancer types,” Dr. David said.

In an interview, Katarzyna Jerzak, MD, MSc, a medical oncologist with Sunnybrook Odette Cancer Center in Toronto, said the findings are promising, although the study is small and the patients are similar. Toxicity was limited, and a 12-month delay in a switch to therapy – reached by 46% – “is very meaningful for patients.” She added that “the positive results should serve as motivation to investigate the strategy further.”

Dr. David said a larger trial called AVATAR 2 is funded and in the works. It will have more patients and more breast cancer subtypes.

The study was funded by the Donald Ratcliffe and Phyllis McLeod Trust. Dr. David disclosed grant/research funding from Roche Genentech, and other authors reported various disclosures including relationships with AstraZeneca, Pfizer, Gilead, and others.

– Stereotactic ablative body radiotherapy (SABR) appeared to delay the need for changes in systemic therapy in postmenopausal patients with oligoprogressive luminal ER-positive, HER2-negative breast cancer, according to a new phase 2 study.

In the AVATAR trial, patients with one to five metastatic lesions who’d been treated with cyclin-dependent kinase (CDK) 4/6 inhibitors and aromatase inhibitors for at least 6 months underwent SABR. Of those, 47% had event-free survival of more than 6 months, an unexpectedly high figure, reported radiation oncologist Steven David, MBBS, of Peter MacCallum Cancer Center, Melbourne, and colleagues at the annual meeting of the American Society for Radiation Oncology.

“We found surprisingly that SABR delayed a change in therapy by 10 months, which is great for patients. Also, one in three patients had a second round of SABR,” said Dr. David in an interview. “This trial provides the first prospective evidence to delay a change in therapy in this population, and this strategy is ready to go now.”

According to Dr. David, oligoprogressive luminal, ER-positive, HER2-negative, advanced breast cancer cannot be cured. However, patients can live more than 10 years in some cases, and an early treatment – CDK 4/6 inhibitors and aromatase inhibitors – is well tolerated. “Patients can lead a normal life and avoid chemo” as long as those medications keep working.

The goal of the study was to determine if SABR is helpful in these patients. The treatment, which produces highly focused radiation, “has very few side effects and does a great job in eliminating progressing metastases,” Dr. David said.

For the study, researchers recruited 32 subjects at 13 Australian sites. Participants could not have had leptomeningeal disease, previous chemotherapy for metastatic disease, or prior radiotherapy to an oligoprogressing lesion. Most metastases were to bone (n = 44, 71%), node (systemic, n = 8; 13%) and lung (n = 4; 6%).

The patients were treated with SABR, most commonly 24 Gy (n = 25; 43%) and 20 Gy (n = 10; 17%); half had one lesion treated (50%), and 25% had two lesions treated.

The median follow-up was 15.8 months. The median event-free survival was 5.2 months (95% confidence interval, 3.1-9.4 months), with events defined as progression within 6 months or in at least three lesions. Fifteen patients (47%) reached event-free survival of 6 or more months.

Elysia Donovan, MD, MSc, a radiation oncologist at McMaster University, Hamilton, Ont., said in an interview that the new study is thoughtfully designed, although it’s not definitive. “At this point we still do not know the optimal treatment regimen for oligoprogressive breast cancer. The findings of this trial are promising and exciting. However, further randomized trials are required before routine implementation in clinical practice. For now, patients should be considered in a case by case basis with multidisciplinary discussion to determine the optimal systemic therapy regimen at oligoprogression and whether SABR may provide benefit.”

False-positive Pap smear may indicate genitourinary syndrome

Article Type
Changed

 

TOPLINE:

A Pap smear result indicating cervical dysplasia may actually be an early signal of genitourinary syndrome (vaginal atrophy) and can be treated effectively with local estrogen, according to a poster presented at The Menopause Society 2023 annual meeting.

METHODOLOGY:

  • Starting in 2010, researchers in Florida and Antigua saw an increase in the number of perimenopausal women with no history of cervical abnormalities and low risk for sexually transmitted infections (STIs) presenting with abnormal Pap smears at their clinics.
  • They studied 1,500 women aged 30-70 from several clinics. The women had low risk for STIs, a maximum of two sexual partners, and the presence of cervical dysplasia over a period of 12 years.

TAKEAWAY:

  • Nearly all (96.7%) of the women who received local estrogen treatment had a normal Pap smear following therapy.
  • A high number of patients who initially presented with cervical dysplasia underwent interventions such as colposcopies, biopsies, LEEP excisions, cryotherapy, cone biopsies, and hysterectomies because of cervical atrophy.
  • The researchers concluded that local estrogen treatment could save patients money spent on treatments for cervical atrophy.
  • Some women who underwent cone biopsies and hysterectomies and did not receive local estrogen still had vaginal dysplasia.

IN PRACTICE:

“In this study, we report an early sign of genitourinary syndrome of menopause: false positive cervical dysplasia caused by cervicovaginal atrophy resulting from decreased estrogen levels during perimenopause,” say the investigators. “We also demonstrate how the use of local estrogen therapy can prevent a significant number of interventions and procedures, resulting in significant cost savings. This is particularly relevant as the number of Pap smears conducted in this population represents 50%-60% of all Pap smears performed on women.”

SOURCE:

The data were presented at The Menopause Society 2023 annual meeting. The study was led by Alberto Dominguez-Bali, MD, from the Miami Center for Obstetrics, Gynecology and Human Sexuality.

LIMITATIONS:

The study authors report no limitations.

DISCLOSURES:

The authors report no relevant financial relationships.

Weight loss with semaglutide maintained for up to 3 years

Article Type
Changed

Once weekly glucagon-like peptide 1 receptor agonist (GLP-1 RA) semaglutide (Ozempic, Novo Nordisk) significantly improved hemoglobin A1c level and body weight for up to 3 years in a large cohort of adults with type 2 diabetes, show real-world data from Israel.

Treatment with semaglutide was associated with reductions in both A1c (–0.77%; P < .001) and body weight (–4.7 kg; P < .001) at 6 months of treatment. These reductions were maintained for up to 3 years and, in particular, in those patients with higher adherence to the therapy.

Avraham Karasik, MD, from the Institute of Research and Innovation at Maccabi Health Services, Tel Aviv, led the study and presented the work as a poster at this year’s annual meeting of the European Association for the Study of Diabetes.

“We found a clinically relevant improvement in blood sugar control and weight loss after 6 months of treatment, comparable with that seen in randomized trials,” said Dr. Karasik during an interview. “Importantly, these effects were sustained for up to 3 years, supporting the use of once weekly semaglutide for the long-term management of type 2 diabetes.”

Esther Walden, RN, deputy head of care at Diabetes UK, appreciated that the real-world findings reflected those seen in the randomized controlled trials. “This study suggests that improvements in blood sugars and weight loss can potentially be sustained in the longer term for adults with type 2 diabetes taking semaglutide as prescribed.”
 

Large scale, long term, and real world

Dr. Karasik explained that in Israel, there are many early adopters of once weekly semaglutide, and as such, it made for a large sample size, with a significant use duration for the retrospective study. “It’s a popular drug and there are lots of questions about durability of effect,” he pointed out.

Though evidence from randomized controlled trials support the effectiveness of once weekly semaglutide to treat type 2 diabetes, these studies are mostly of relatively short follow-up, explained Dr. Karasik, pointing out that long-term, large-scale, real-world data are needed. “In real life, people are acting differently to the trial setting and some adhere while others don’t, so it was interesting to see the durability as well as what happens when people discontinue treatment or adhere less.”

“Unsurprisingly, people who had a higher proportion of days covered ([PDC]; the total days of semaglutide use as a proportion of the total number of days followed up) had a higher effect,” explained Dr. Karasik, adding that, “if you don’t take it, it doesn’t work.”

A total of 23,442 patients were included in the study, with 6,049 followed up for 2 years or more. Mean baseline A1c was 7.6%-7.9%; body mass index (BMI) was 33.7-33.8 kg/m2; metformin was taken by 84%-88% of participants; insulin was taken by 30%; and 31% were treated with another GLP-1 RA prior to receiving semaglutide.

For study inclusion, participants were required to have had redeemed at least one prescription for subcutaneous semaglutide (0.25, 0.5, or 1 mg), and had at least one A1c measurement 12 months before and around 6 months after the start of semaglutide.

The primary outcome was change in A1c from baseline to the end of the follow-up at 6, 12, 18, 24, 30, and 36 months. Key secondary outcomes included change in body weight from baseline to the end of the follow-up (36 months); change in A1c and body weight in subgroups of patients who were persistently on therapy (at 12, 24, 36 months); and change in A1c and body weight in subgroups stratified by baseline characteristics. There was also an exploratory outcome, which was change in A1c and weight after treatment discontinuation. Dr. Karasik presented some of these results in his poster.

Median follow-up was 17.6 months in the total population and was 29.9 months in those who persisted with therapy for 2 years or more. “We have over 23,000 participants so it’s a large group, and these are not selected patients so the generalizability is better.”
 

 

 

Three-year sustained effect

Results from the total population showed that A1c lowered by a mean of 0.77% (from 7.6% to 6.8%) and body weight reduced by 4.7 kg (from 94.1 kg to 89.7 kg) after 6 months of treatment. These reductions were maintained during 3 years of follow-up in around 1,000 patients.

A significant 75% of participants adhered to once weekly semaglutide (PDC of more than 60%) within the first 6 months. In patients who used semaglutide for at least 2 years, those with high adherence (PDC of at least 80%) showed an A1c reduction of 0.76% after 24 months and of 0.43% after 36 months. Body weight was reduced by 6.0 kg after 24 months and 5.8 kg after 36 months.

Reductions in both A1c and weight were lower in patients with PDC of below 60%, compared with those with PDC of 60%-79% or 80% or over (statistically significant difference of P < .05 for between-groups differences for both outcomes across maximum follow-up time).

As expected, among patients who were GLP-1 RA–naive, reductions in A1c level and body weight were more pronounced, compared with GLP-1 RA–experienced patients (A1c reduction, –0.87% vs. –0.54%; weight loss, –5.5 kg vs. –3.0 kg, respectively; P < .001 for between-groups difference for both outcomes).

Dr. Karasik reported that some patients who stopped taking semaglutide did not regain weight immediately and that this potential residual effect after treatment discontinuation merits additional investigation. “This is not like in the randomized controlled trials. I don’t know how to interpret it, but that’s the observation. A1c did increase a little when they stopped therapy, compared to those with PDC [of 60%-79% or 80% or over] (P < .05 for between-groups difference for both outcomes in most follow-up time).”

He also highlighted that in regard to the long-term outcomes, “unlike many drugs where the effect fades out with time, here we don’t see that happening. This is another encouraging point.”

Results from the total population showed that A1c lowered by a mean of 0.77% (from 7.6% to 6.8%) and body weight reduced by 4.7 kg (from 94.1 kg to 89.7 kg) after 6 months of treatment. These reductions were maintained during 3 years of follow-up in around 1,000 patients.

“We found a clinically relevant improvement in blood sugar control and weight loss after 6 months of treatment, comparable with that seen in randomized trials,” said Dr. Karasik during an interview. “Importantly, these effects were sustained for up to 3 years, supporting the use of once weekly semaglutide for the long-term management of type 2 diabetes.”

Esther Walden, RN, deputy head of care at Diabetes UK, appreciated that the real-world findings reflected those seen in the randomized controlled trials. “This study suggests that improvements in blood sugars and weight loss can potentially be sustained in the longer term for adults with type 2 diabetes taking semaglutide as prescribed.”
 

Large scale, long term, and real world

Dr. Karasik explained that in Israel, there are many early adopters of once weekly semaglutide, and as such, it made for a large sample size, with a significant use duration for the retrospective study. “It’s a popular drug and there are lots of questions about durability of effect,” he pointed out.

Though evidence from randomized controlled trials support the effectiveness of once weekly semaglutide to treat type 2 diabetes, these studies are mostly of relatively short follow-up, explained Dr. Karasik, pointing out that long-term, large-scale, real-world data are needed. “In real life, people are acting differently to the trial setting and some adhere while others don’t, so it was interesting to see the durability as well as what happens when people discontinue treatment or adhere less.”

“Unsurprisingly, people who had a higher proportion of days covered ([PDC]; the total days of semaglutide use as a proportion of the total number of days followed up) had a higher effect,” explained Dr. Karasik, adding that, “if you don’t take it, it doesn’t work.”

A total of 23,442 patients were included in the study, with 6,049 followed up for 2 years or more. Mean baseline A1c was 7.6%-7.9%; body mass index (BMI) was 33.7-33.8 kg/m2; metformin was taken by 84%-88% of participants; insulin was taken by 30%; and 31% were treated with another GLP-1 RA prior to receiving semaglutide.

For study inclusion, participants were required to have had redeemed at least one prescription for subcutaneous semaglutide (0.25, 0.5, or 1 mg), and had at least one A1c measurement 12 months before and around 6 months after the start of semaglutide.

The primary outcome was change in A1c from baseline to the end of the follow-up at 6, 12, 18, 24, 30, and 36 months. Key secondary outcomes included change in body weight from baseline to the end of the follow-up (36 months); change in A1c and body weight in subgroups of patients who were persistently on therapy (at 12, 24, 36 months); and change in A1c and body weight in subgroups stratified by baseline characteristics. There was also an exploratory outcome, which was change in A1c and weight after treatment discontinuation. Dr. Karasik presented some of these results in his poster.

Median follow-up was 17.6 months in the total population and was 29.9 months in those who persisted with therapy for 2 years or more. “We have over 23,000 participants so it’s a large group, and these are not selected patients so the generalizability is better.”
 

 

 

Three-year sustained effect

Results from the total population showed that A1c lowered by a mean of 0.77% (from 7.6% to 6.8%) and body weight reduced by 4.7 kg (from 94.1 kg to 89.7 kg) after 6 months of treatment. These reductions were maintained during 3 years of follow-up in around 1,000 patients.

A significant 75% of participants adhered to once weekly semaglutide (PDC of more than 60%) within the first 6 months. In patients who used semaglutide for at least 2 years, those with high adherence (PDC of at least 80%) showed an A1c reduction of 0.76% after 24 months and of 0.43% after 36 months. Body weight was reduced by 6.0 kg after 24 months and 5.8 kg after 36 months.

Reductions in both A1c and weight were lower in patients with PDC of below 60%, compared with those with PDC of 60%-79% or 80% or over (statistically significant difference of P < .05 for between-groups differences for both outcomes across maximum follow-up time).

As expected, among patients who were GLP-1 RA–naive, reductions in A1c level and body weight were more pronounced, compared with GLP-1 RA–experienced patients (A1c reduction, –0.87% vs. –0.54%; weight loss, –5.5 kg vs. –3.0 kg, respectively; P < .001 for between-groups difference for both outcomes).

Dr. Karasik reported that some patients who stopped taking semaglutide did not regain weight immediately and that this potential residual effect after treatment discontinuation merits additional investigation. “This is not like in the randomized controlled trials. I don’t know how to interpret it, but that’s the observation. A1c did increase a little when they stopped therapy, compared to those with PDC [of 60%-79% or 80% or over] (P < .05 for between-groups difference for both outcomes in most follow-up time).”

He also highlighted that in regard to the long-term outcomes, “unlike many drugs where the effect fades out with time, here we don’t see that happening. This is another encouraging point.”

Hold blood thinners during thyroid nodule biopsy?

Article Type
Changed

– The routine practice of holding use of blood-thinning medications at the time of an ultrasound-guided thyroid nodule fine needle aspiration (FNA) biopsy shows no significant safety benefit in preventing the risk of complications such as hematomas or nondiagnostic results; however, experts suggest using individualized decision-making with the practice.

“Our data indicates that there is no need to routinely hold anticoagulation or antiplatelet therapy prior to thyroid nodule FNA biopsy,” first author Michelle Lundholm, MD, of the Cleveland Clinic said in an interview.

“[The practice] impacts neither the safety of the FNA procedure nor the adequacy of the sample,” she said.

The late-breaking research was presented at the annual meeting of the American Thyroid Association.

Key concerns in the use of anticoagulants and/or antiplatelet medications during thyroid nodule FNA biopsy include the increased risk of postprocedural hematoma or nondiagnostic results, with, for instance, one study showing higher rates of nondiagnostic results among patients remaining on aspirin therapy during the FNA biopsy.

However, holding the medically indicated therapies can have risks of its own, including concerns of thrombotic events such as deep vein thrombosis or stroke. However, evidence comparing the risks with each strategy in thyroid nodule FNA is lacking.

To investigate, Dr. Lundholm and colleagues conducted a review of data on 2,945 patients who had undergone a total of 4,741 thyroid nodule FNAs in the Cleveland Clinic’s diverse network of centers between 2010 and 2023. The patients had a mean age of 66.2; 69.6% were female and 75.7% were White.

All patients had an active prescription for an anticoagulant or antiplatelet medication up to 10 days prior to their thyroid nodule FNA biopsy. Specifically, 73.7% were on 81 mg aspirin, 8.5% were on 325 mg aspirin, 7.4% were taking other antiplatelet medication such as clopidogrel or ticagrelor; 7.0% were on warfarin, 8.2% were on a direct oral anticoagulant (DOAC); 6.3% were on heparin products; and 10.3% of patients were on two or more blood-thinning medications.

The results show that, overall, 13.0% (n =  614) of the thyroid nodule FNA biopsies had nondiagnostic results, which is within the average rates in the literature ranging from 6% to 36%, Dr. Lundholm noted.

Blood-thinning medications were held in 20.8% of the FNA biopsies, however, there were no differences in nondiagnostic results between those who had drugs held (12.2%) or who continued on the medications (13.2%; P  = .41).

After multivariate adjustment for age and sex, the lack of significant differences in receiving nondiagnostic results among those who did or did not continue blood thinners was consistent overall (odds ratio, 1.10; P = .38), and in the specific groups of 81 mg aspirin (OR, 1.00; P = .99); 325 mg aspirin or clopidogrel/ticagrelor (OR, 1.50; P = .15); or warfarin, DOAC, or heparin/enoxaparin (OR, 1.27; P = .27).

In terms of hematoma risk, ED records within 48 hours of the FNA showed that such events were rare, with only one hematoma occurring overall, involving a patient who was on 81 mg of aspirin for secondary stroke prevention that was not interrupted for FNA biopsy. The patient was discharged and did not require medical intervention.  

Four other hematomas occurred among patients who were not being treated with blood thinners, with none requiring intervention.

The findings indicate that “hematoma can happen in any patient, but rarely requires intervention,” Dr. Lundholm said.

However, while thrombotic events were also rare, serious events occurred in three patients within 48 hours of the thyroid nodule FNA biopsy when a blood thinner was withheld, including ischemic strokes among two patients who were on a DOAC and 81 mg of aspirin that were withheld, and one MI occurring in a patient on a DOAC that was held for the FNA.

Unlike hematomas, the thrombotic events each had significant long‐term sequelae, Dr. Lundholm noted.

“Having these ischemic strokes and heart attack really led to a change in these patients’ lives,” she said. “While we can never assume that [the events occurred] because the blood-thinner therapy was held, the timing within 48 hours is certainly very suspicious.”

There were no deep vein thrombosis or pulmonary embolism events.
 

 

 

Withholding practices vary

In a previous survey of 60 clinicians conducted by Dr. Lundholm and colleagues, wide variation was reported in the rates of withholding antiplatelet or anticoagulant medications prior to thyroid nodule FNA biopsy.

The survey of endocrinologists, interventional radiologists, and ear, nose, and throat providers showed rates of withholding 81 mg of aspirin prior to FNA biopsy of just 13.3%, withholding 325 mg of aspirin, 15%, other antiplatelets, 41.7%, warfarin, 73.3%, DOACs, 43.3%, and heparin, 43.3%.

“We found heterogeneity in withholding patterns even within the same department,” she said. “This is reflective of the fact that evidence is mixed.”

Guidelines on the issue from the Society of Interventional Radiology and the International Society on Thrombosis and Hemostasis recommend that providers consider the balance of the procedure and patient bleeding risk versus the clotting risk, Dr. Lundholm noted.

However, a caveat is that those recommendations are based on pooled data from similar minimal risk procedures, she explained.

“There is a lack of data on bleeding risks for individual interventions like thyroid biopsy, and, as such, there is no specific procedure-related risk determination.”

Meanwhile, Dr. Lundholm said that notable limitations regarding the current research include that the study may not have caught all patient cases that presented with complications to an outside ED.

Furthermore, the study results pertain to the safety of blood thinners in routine use, with key aspects that can influence complication rates, such as provider experience, needle size, and nodule features unavailable for analysis.
 

At MD Anderson, case-by-case

Commenting on the research, Anastasios Maniakas, MD, PhD, of the department of head and neck surgery, division of surgery, University of Texas MD Anderson Cancer Center, Houston, said the study is important, noting that, at his institution, the approach regarding holding blood-thinning medications is generally determined on an individual basis.

“I think this was a good study, but I don’t think it’s practice changing because these decisions may differ on a case-by-case basis,” Dr. Maniakas, who comoderated the session, said in an interview.

“At MD Anderson, we probably have one of the highest volumes in the country for thyroid nodule FNAs, and we do hold blood thinners because we often have to do more significant biopsies, with multiple passages and larger needles to be used,” Dr. Maniakas said.

“If you’re going to use perhaps the smallest possible gauge needle, then I think it is reasonable to not hold blood thinners, but if you’re going to be doing multiple passages and you need to do a core biopsy and use a large needle, then it is wiser to try to hold the medications for a day or 2.

“We haven’t had any complications, but I think there’s still a lot of apprehension to not hold blood thinners,” Dr. Maniakas said. “So, overall, I think the message is that it has to be on a case-by-case basis.”

Dr. Lundholm and Dr. Maniakas reported no relevant financial relationships.

Tirzepatide with insulin glargine improves type 2 diabetes

Article Type
Changed

Once-weekly tirzepatide (Mounjaro, Lilly) added to insulin glargine resulted in greater reductions in hemoglobin A1c along with more weight loss and less hypoglycemia, compared with prandial insulin lispro (Humalog, Sanofi), for patients with inadequately controlled type 2 diabetes, show data from the SURPASS-6 randomized clinical trial.

Tirzepatide led to a statistically and clinically significant reduction in mean A1c, at −2.1%, compared with insulin lispro, at −1.1%, by week 52. It also resulted in a higher percentage of participants meeting an A1c target of less than 7.0%, wrote the researchers, whose study was presented at the annual meeting of the European Association for the Study of Diabetes and was published simultaneously in JAMA.

Also, daily insulin glargine use was substantially lower among participants who received tirzepatide, compared with insulin lispro. Insulin glargine was administered at a dosage 13 IU/day; insulin lispro was administered at a dosage of 62 IU/day. “At the highest dose, some patients stopped their insulin [glargine] in the tirzepatide arm,” said Juan Pablo Frias, MD, medical director and principal investigator of Velocity Clinical Research, Los Angeles, who presented the findings. “We demonstrated clinically meaningful and superior glycemic and body weight control with tirzepatide compared with insulin lispro, while tirzepatide was also associated with less clinically significant hypoglycemia.”

Weight improved for participants who received tirzepatide compared with those who received insulin lispro, at –10 kg and +4 kg respectively. The rate of clinically significant hypoglycemia (blood glucose < 54 mg/dL) or severe hypoglycemia was tenfold lower with tirzepatide, compared with insulin lispro.

The session dedicated to tirzepatide was comoderated by Apostolos Tsapas, MD, professor of medicine and diabetes, Aristotle University, Thessaloniki, Greece, and Konstantinos Toulis, MD, consultant in endocrinology and diabetes, General Military Hospital, Thessaloniki, Greece. Dr. Toulis remarked that, in the chronic disease setting, management and treatment intensification are challenging to integrate, and there are barriers to adoption in routine practice. “This is particularly true when it adds complexity, as in the case of multiple prandial insulin injections on top of basal insulin in suboptimally treated individuals with type 2 diabetes.

“Demonstrating superiority over insulin lispro in terms of the so-called trio of A1c, weight loss, and hypoglycemic events, tirzepatide offers both a simpler to adhere to and a more efficacious treatment intensification option.” He noted that, while long-term safety data are awaited, “this seems to be a definite step forward from any viewpoint, with the possible exception of the taxpayer’s perspective.”

Dr. Tsapas added: “These data further support the very high dual glucose and weight efficacy of tirzepatide and the primary role of incretin-related therapies amongst the injectables for the treatment of type 2 diabetes.”
 

Tirzepatide 5, 10, 15 mg vs. insulin lispro in addition to insulin glargine

The researchers aimed to assess the efficacy and safety of adding once-weekly tirzepatide, compared with thrice-daily prandial insulin lispro, as an adjunctive therapy to insulin glargine for patients with type 2 diabetes that was inadequately controlled with basal insulin.

Tirzepatide activates the body’s receptors for glucose-dependent insulinotropic polypeptide and glucagonlike peptide–1 (GLP-1). The study authors noted that “recent guidelines support adding an injectable incretin-related therapy such as GLP-1 receptor agonist for glycemic control, rather than basal insulin, when oral medications are inadequate.”

The open-label, phase 3b clinical trial drew data from 135 sites across 15 countries and included 1,428 adults with type 2 diabetes who were taking basal insulin. Participants were randomly assigned in a 1:1:1:3 ratio to receive once-weekly subcutaneous injections of tirzepatide (5 mg [n = 243], 10 mg [n = 238], or 15 mg [n = 236]) or prandial thrice-daily insulin lispro (n = 708).

Both arms were well matched. The average age was 60 years, and 60% of participants were women. The average amount of time patients had type 2 diabetes was 14 years; 85% of participants continued taking metformin. The average A1c level was 8.8% at baseline. Patients were categorized as having obesity (average body mass index, 33 kg/m2). The average insulin glargine dose was 46 units, or 0.5 units/kg.

Outcomes included noninferiority of tirzepatide (pooled cohort) compared with insulin lispro, both in addition to insulin glargine; and A1c change from baseline to week 52 (noninferiority margin, 0.3%). Key secondary endpoints included change in body weight and percentage of participants who achieved an A1c target of less than 7.0%.

About 90% of participants who received the study drug completed the study, said Dr. Frias. “Only 0.5% of tirzepatide patients needed rescue therapy, while only 2% of the insulin lispro did.”

Prior to optimization, the average insulin glargine dose was 42 IU/kg; during optimization, it rose to an average of 46 IU/kg. “At 52 weeks, those on basal-bolus insulin found their insulin glargine dose stayed flat while insulin lispro was 62 units,” reported Dr. Frias. “The three tirzepatide doses show a reduction in insulin glargine, such that the pooled dose reached an average of 11 units, while 20% actually came off their basal insulin altogether [pooled tirzepatide].”

Tirzepatide (pooled) led to the recommended A1c target of less than 7.0% for 68% of patients versus 36% of patients in the insulin lispro group.

About 68% of the patients who received tirzepatide (pooled) achieved the recommended A1c target of less than 7.0% versus 36% of patients in the insulin lispro group.

“Individual tirzepatide doses and pooled doses showed significant reduction in A1c and up to a 2.5% reduction,” Dr. Frias added. “Normoglycemia was obtained by a greater proportion of patients on tirzepatide doses versus basal-bolus insulin – one-third in the 15-mg tirzepatide dose.”
 

 

 

Body weight reduction of 10% or more with tirzepatide

Further, at week 52, weight loss of 5% or more was achieved by 75.4% of participants in the pooled tirzepatide group, compared with 6.3% in the prandial lispro group. The weight loss was accompanied by clinically relevant improvements in cardiometabolic parameters.

In an exploratory analysis, weight loss of 10% or more was achieved by a mean of 48.9% of pooled tirzepatide-treated participants at week 52, compared with 2% of those taking insulin lispro, said Dr. Frias.

“It is possible that the body weight loss induced by tirzepatide therapy and its reported effect in reducing liver fat content may have led to an improvement in insulin sensitivity and decreased insulin requirements,” wrote the researchers in their article.

Hypoglycemia risk and the weight gain observed with complex insulin regimens that include prandial insulin have been main limitations to optimally up-titrate insulin therapy in clinical practice, wrote the authors.

Dr. Frias noted that, in this study, 48% of patients who received insulin lispro experienced clinically significant hypoglycemia, while only 10% of patients in the tirzepatide arms did. “This was 0.4 episodes per patient-year versus 4.4 in tirzepatide and insulin lispro respectively.”

There were more reports of adverse events among the tirzepatide groups than the insulin lispro group. “Typically, with tirzepatide, the commonest adverse events were GI in origin and were mild to moderate.” Rates were 14%-26% for nausea, 11%-15% for diarrhea, and 5%-13% for vomiting.

The study was sponsored by Eli Lilly. Dr. Frias has received grants from Eli Lilly paid to his institution during the conduct of the study and grants, personal fees, or nonfinancial support from Boehringer Ingelheim, Pfizer, Merck, Altimmune, 89BIO, Akero, Carmot Therapeutics, Intercept, Janssen, Madrigal, Novartis, Eli Lilly, Sanofi, and Novo Nordisk outside the submitted work.

Once-weekly tirzepatide (Mounjaro, Lilly) added to insulin glargine resulted in greater reductions in hemoglobin A1c along with more weight loss and less hypoglycemia, compared with prandial insulin lispro (Humalog, Sanofi), for patients with inadequately controlled type 2 diabetes, show data from the SURPASS-6 randomized clinical trial.

Tirzepatide led to a statistically and clinically significant reduction in mean A1c, at −2.1%, compared with insulin lispro, at −1.1%, by week 52. It also resulted in a higher percentage of participants meeting an A1c target of less than 7.0%, wrote the researchers, whose study was presented at the annual meeting of the European Association for the Study of Diabetes and was published simultaneously in JAMA.

Also, daily insulin glargine use was substantially lower among participants who received tirzepatide, compared with insulin lispro. Insulin glargine was administered at a dosage 13 IU/day; insulin lispro was administered at a dosage of 62 IU/day. “At the highest dose, some patients stopped their insulin [glargine] in the tirzepatide arm,” said Juan Pablo Frias, MD, medical director and principal investigator of Velocity Clinical Research, Los Angeles, who presented the findings. “We demonstrated clinically meaningful and superior glycemic and body weight control with tirzepatide compared with insulin lispro, while tirzepatide was also associated with less clinically significant hypoglycemia.”

Weight improved for participants who received tirzepatide compared with those who received insulin lispro, at –10 kg and +4 kg respectively. The rate of clinically significant hypoglycemia (blood glucose < 54 mg/dL) or severe hypoglycemia was tenfold lower with tirzepatide, compared with insulin lispro.

The session dedicated to tirzepatide was comoderated by Apostolos Tsapas, MD, professor of medicine and diabetes, Aristotle University, Thessaloniki, Greece, and Konstantinos Toulis, MD, consultant in endocrinology and diabetes, General Military Hospital, Thessaloniki, Greece. Dr. Toulis remarked that, in the chronic disease setting, management and treatment intensification are challenging to integrate, and there are barriers to adoption in routine practice. “This is particularly true when it adds complexity, as in the case of multiple prandial insulin injections on top of basal insulin in suboptimally treated individuals with type 2 diabetes.

“Demonstrating superiority over insulin lispro in terms of the so-called trio of A1c, weight loss, and hypoglycemic events, tirzepatide offers both a simpler to adhere to and a more efficacious treatment intensification option.” He noted that, while long-term safety data are awaited, “this seems to be a definite step forward from any viewpoint, with the possible exception of the taxpayer’s perspective.”

Dr. Tsapas added: “These data further support the very high dual glucose and weight efficacy of tirzepatide and the primary role of incretin-related therapies amongst the injectables for the treatment of type 2 diabetes.”

Salvage option to replace transplant in r/r Hodgkin lymphoma?

Article Type
Changed

Children and young adults with low-risk relapsed or refractory classic Hodgkin lymphoma may be able to skip autologous stem cell transplant.

Patients who received second-line chemoimmunotherapy with nivolumab-brentuximab vedotin, with or without bendamustine, and proceeded to involved-site radiation appeared to have similar survival outcomes to those who received the chemoimmunotherapy combination plus the current second-line standard of care, which includes high-dose therapy and autologous stem cell transplant.

Among 28 patients with low-risk relapsed or refractory Hodgkin lymphoma followed for a median of 32 months, 3-year event-free survival without autologous stem cell transplant was 86.9% and 3-year progression-free survival was 95%, reported Brad Hoppe, MD, MPH, from the Mayo Clinic in Jacksonville, Fla. In contrast, 1-year progression-free survival was 91% among the 44 standard-risk patients who received high-dose therapy and autologous stem cell transplant, according to results of a trial the investigators published online in Blood in late 2022.

The latest results from the phase 2 CheckMate 744 trial were reported at the annual meeting of the American Society of Radiation Oncology.

“The findings suggest that children, adolescents, and young adults with low-risk relapsed classic Hodgkin lymphoma can be salvaged with low-toxicity chemoimmunotherapy and may not require high-dose therapy and transplant for a cure,” Dr. Hoppe said in an oral abstract session.

Andrea Ng, MD, MPH, a radiation oncologist who specializes in treating patients with Hodgkin lymphoma and other hematologic malignancies, said that, while the number of patients in the study was small and the follow-up too short, this option is “certainly something that’s very promising for the future.”

“The use of transplant in relapsed patients, which we have been doing for decades, is based on two very old, small, randomized studies,” said Dr. Ng, from the Dana-Farber Cancer Institute in Boston, who moderated the session.

“So, do we really need to transplant everybody? In the back of our minds, we think that we may be overtreating some patients,” she said.

Several small, retrospective studies exploring treatment with conventional chemotherapy with or without radiation therapy and without transplant in patients with relapsed or refractory Hodgkin lymphoma have demonstrated only modest results.

The CheckMate 744 trial, however, was designed to examine a risk-adapted and response-adapted approach to treating children, adolescents, and young adults with relapsed or refractory classic Hodgkin lymphoma within the setting of modern immunotherapy and targeted therapy. This approach was developed jointly by investigators with the Children’s Oncology Group and Euronet.

In the nonrandomized trial, patients were stratified into low-risk or standard-risk disease categories based on an algorithm that included factors at the time of initial diagnosis and relapse.

Patients were considered low-risk for relapse in three scenarios: (1) if they had initial stage IA or IIA disease that relapsed at least 1 year after the end of therapy; (2) if they had initial stage IA or IIA disease that relapsed between 3 and 12 months from the end of therapy but had received no more than three cycles of chemotherapy and no radiation therapy; or (3) if they had initial stage IB, IIB, or IIIA disease that relapsed more than 12 months after the end of first-line therapy.

To be included in the low-risk category, patients also had to be free of B symptoms or extranodal disease, free of relapse in prior radiation therapy fields, and have no more than four sites of lymphoma. 

Low-risk patients were treated with a combination of nivolumab and brentuximab vedotin, which could be followed by additional brentuximab vedotin and bendamustine for those with a suboptimal response. Patients who achieved complete molecular remission after induction went on to consolidation therapy with involved-site radiation at a total dose of 30 Gy.

Patients considered standard-risk for relapse received the same nivolumab-brentuximab vedotin combination, with or without bendamustine, and then went on to high-dose therapy and autologous stem cell transplant.

In other results for the previously mentioned study published in Blood, the 44 standard-risk patients who received high-dose therapy and autologous stem cell transplant had an objective response rate of 95% – 86% of patients achieved complete molecular remission, and 9% achieved partial molecular remission.

At ASTRO, Dr. Hoppe reported results for the 28 patients with low-risk disease. One patient discontinued nivolumab/brentuximab vedotin after two cycles because of skin toxicity and was lost to follow-up. Of the remaining 27 patients, 21 had complete molecular remission after four cycles of the combination, and these patients went on to an additional two cycles of the combination, with 19 of 21 receiving involved-site radiation consolidation. 

Six patients who had either a partial molecular remission or no response were given two additional cycles of brentuximab vedotin plus bendamustine. Of this group, three went on to complete molecular remission and received involved-site radiation consolidation on protocol. The remaining three patients who did not experience complete molecular remission received involved-site radiation off protocol.

The rate of complete molecular remission after four cycles of induction was 82.1%, and the rate of partial molecular remission was 14.3%, for an objective response rate of 96.4%. The respective response rates with the addition of two cycles of brentuximab vedotin and bendamustine were 92.9% and 7.1%, for an objective response rate of 100%, Dr. Hoppe reported.

Overall, at a median follow-up of 32 months, the 3-year event-free survival rate without transplant was 86.9%, and the 3-year progression-free survival rate was 95%.

Treatment-related adverse events of any grade occurred in 22 patients (78.6%) after induction, with 7 of those events (25%) being grade 3 or 4 in severity. Grade 3 or 4 events consisted of skin and subcutaneous tissue disorders in 3 patients, elevated liver function tests in 3 patients, and blood and lymphatic system disorders in 1 patient.

There were no new toxicities detected within 100 days of treatment.

“The results that Dr. Hoppe showed us are really, really good,” Dr. Ng said. And “the volume of treatment is pretty tiny, so I think we can safely say that long-term toxicities are very, very minimal.”

The study was supported by Bristol-Myers Squibb in collaboration with Seagen, Euronet-Paediatric Hodgkin Lymphoma, and the Children’s Oncology Group. Dr. Hoppe reported serving on a scientific advisory committee for Merck. Dr. Ng reported having no relevant conflicts of interest.

At ASTRO, Dr. Hoppe reported results for the 28 patients with low-risk disease. One patient discontinued nivolumab/brentuximab vedotin after two cycles because of skin toxicity and was lost to follow-up. Of the remaining 27 patients, 21 had complete molecular remission after four cycles of the combination, and these patients went on to an additional two cycles of the combination, with 19 of 21 receiving involved-site radiation consolidation. 

Six patients who had either a partial molecular remission or no response were given two additional cycles of brentuximab vedotin plus bendamustine. Of this group, three went on to complete molecular remission and received involved-site radiation consolidation on protocol. The remaining three patients who did not experience complete molecular remission received involved-site radiation off protocol.

The rate of complete molecular remission after four cycles of induction was 82.1%, and the rate of partial molecular remission was 14.3%, for an objective response rate of 96.4%. The respective response rates with the addition of two cycles of brentuximab vedotin and bendamustine were 92.9% and 7.1%, for an objective response rate of 100%, Dr. Hoppe reported.

Overall, at a median follow-up of 32 months, the 3-year event-free survival rate without transplant was 86.9%, and the 3-year progression-free survival rate was 95%.

Treatment-related adverse events of any grade occurred in 22 patients (78.6%) after induction, with 7 of those events (25%) being grade 3 or 4 in severity. Grade 3 or 4 events consisted of skin and subcutaneous tissue disorders in 3 patients, elevated liver function tests in 3 patients, and blood and lymphatic system disorders in 1 patient.

There were no new toxicities detected within 100 days of treatment.

“The results that Dr. Hoppe showed us are really, really good,” Dr. Ng said. And “the volume of treatment is pretty tiny, so I think we can safely say that long-term toxicities are very, very minimal.”

The study was supported by Bristol-Myers Squibb in collaboration with Seagen, Euronet-Paediatric Hodgkin Lymphoma, and the Children’s Oncology Group. Dr. Hoppe reported serving on a scientific advisory committee for Merck. Dr. Ng reported having no relevant conflicts of interest.

Children and young adults with low-risk relapsed or refractory classic Hodgkin lymphoma may be able to skip autologous stem cell transplant.

Patients who received second-line chemoimmunotherapy with nivolumab-brentuximab vedotin, with or without bendamustine, and proceeded to involved-site radiation appeared to have similar survival outcomes to those who received the chemoimmunotherapy combination plus the current second-line standard of care, which includes high-dose therapy and autologous stem cell transplant.

Among 28 patients with low-risk relapsed or refractory Hodgkin lymphoma followed for a median of 32 months, 3-year event-free survival without autologous stem cell transplant was 86.9% and 3-year progression-free survival was 95%, reported Brad Hoppe, MD, MPH, from the Mayo Clinic in Jacksonville, Fla. In contrast, 1-year progression-free survival was 91% among the 44 standard-risk patients who received high-dose therapy and autologous stem cell transplant, according to results of a trial the investigators published online in Blood in late 2022.

The latest results from the phase 2 CheckMate 744 trial were reported at the annual meeting of the American Society of Radiation Oncology.

“The findings suggest that children, adolescents, and young adults with low-risk relapsed classic Hodgkin lymphoma can be salvaged with low-toxicity chemoimmunotherapy and may not require high-dose therapy and transplant for a cure,” Dr. Hoppe said in an oral abstract session.

Andrea Ng, MD, MPH, a radiation oncologist who specializes in treating patients with Hodgkin lymphoma and other hematologic malignancies, said that, while the number of patients in the study was small and the follow-up too short, this option is “certainly something that’s very promising for the future.”

“The use of transplant in relapsed patients, which we have been doing for decades, is based on two very old, small, randomized studies,” said Dr. Ng, from the Dana-Farber Cancer Institute in Boston, who moderated the session.

“So, do we really need to transplant everybody? In the back of our minds, we think that we may be overtreating some patients,” she said.

Several small, retrospective studies exploring treatment with conventional chemotherapy with or without radiation therapy and without transplant in patients with relapsed or refractory Hodgkin lymphoma have demonstrated only modest results.

The CheckMate 744 trial, however, was designed to examine a risk-adapted and response-adapted approach to treating children, adolescents, and young adults with relapsed or refractory classic Hodgkin lymphoma within the setting of modern immunotherapy and targeted therapy. This approach was developed jointly by investigators with the Children’s Oncology Group and Euronet.

In the nonrandomized trial, patients were stratified into low-risk or standard-risk disease categories based on an algorithm that included factors at the time of initial diagnosis and relapse.

Patients were considered low-risk for relapse in three scenarios: (1) if they had initial stage IA or IIA disease that relapsed at least 1 year after the end of therapy; (2) if they had initial stage IA or IIA disease that relapsed between 3 and 12 months from the end of therapy but had received no more than three cycles of chemotherapy and no radiation therapy; or (3) if they had initial stage IB, IIB, or IIIA disease that relapsed more than 12 months after the end of first-line therapy.

To be included in the low-risk category, patients also had to be free of B symptoms or extranodal disease, free of relapse in prior radiation therapy fields, and have no more than four sites of lymphoma. 

Low-risk patients were treated with a combination of nivolumab and brentuximab vedotin, which could be followed by additional brentuximab vedotin and bendamustine for those with a suboptimal response. Patients who achieved complete molecular remission after induction went on to consolidation therapy with involved-site radiation at a total dose of 30 Gy.

Patients considered standard-risk for relapse received the same nivolumab-brentuximab vedotin combination, with or without bendamustine, and then went on to high-dose therapy and autologous stem cell transplant.

In other results for the previously mentioned study published in Blood, the 44 standard-risk patients who received high-dose therapy and autologous stem cell transplant had an objective response rate of 95% – 86% of patients achieved complete molecular remission, and 9% achieved partial molecular remission.
