Results from a new phase IIb, 2x2 randomized, open-label trial (GeparSEPTO) showed no improvement in pathologic complete response (pCR) rates when the RANKL inhibitor denosumab was added to anthracycline/taxane-based neoadjuvant chemotherapy in the treatment of primary breast cancer. The study found that a weekly anthracycline/taxane-based neoadjuvant chemotherapy led to improved pCR compared to an every 3-week schedule both overall and in patients with triple-negative breast cancer (TNBC), though it was associated with greater toxicity.

“Currently, I do not see a place for antiosteolytic agents as part of the neoadjuvant therapy in breast cancer,” said lead author Sibylle Loibl, MD, PhD, who is a breast cancer researcher at Goethe (Germany) University. The researchers can’t exclude the possibility of a long-term benefit, and patients will be followed for disease-free and overall survival.

The disappointing result comes after previous studies of denosumab or bisphosphonates as additions to adjuvant therapy reduced metastases and increased survival in breast cancer, prompting optimism that the agents might improve pCR rates and improve survival rates in the neoadjuvant setting.

The failure may be because of the shorter treatment duration, and it’s possible that pCR is not the best endpoint to study for a drug that has long-acting potential, according to Dr. Loibl.

Patients were randomized to 120 mg denosumab every 4 weeks for six cycles or to receive no supplementary treatment. Patients with or without denosumab either received nab-paclitaxel 125 mg/m2 weekly for 12 weeks or on days 1 and 8 every 3 weeks, over four cycles (eight total doses), then epirubicin/cyclophosphamide, 90/600 mg/m2 (every 2 and 3 weeks, respectively). Patients with triple-negative breast cancer also received carboplatin. Patients with ERBB2-positive breast cancer received the trastuzumab biosimilar ABP980 plus pertuzumab.

The study included 780 patients (1 male), with a median age of 49.0 years. There was no difference in pCR among denosumab recipients and nonrecipients (41.0% versus 42.8%; P = .58). Weekly nab-paclitaxel led to a higher pCR rate than a schedule of days 1 and 8 every 3 weeks (44.9% versus 39.0%; P = .06, significance level of alpha = .10). Among subgroups, there was only a difference in pCR rates among those with TNBC (60.4% versus 50.0%; P = .06). Grade 3-4 toxic effects were similar regardless of denosumab exposure, but nonhematologic grade 3-4 toxicity was higher with weekly nab-paclitaxel (33.7% versus 24.1%; P = .004).

“The overall pCR difference (with nab-paclitaxel as neoadjuvant chemotherapy) seems small, but looking at the data from the GeparSEPTO study we would expect a transformation into a better invasive disease-free survival. Looking specifically into patients with TNBC, there is clear pCR increase by using the weekly regimen. With just over 60%, this is the highest pCR rate reported so far for a chemotherapy-only regimen. I would prefer to use nab-paclitaxel also in early breast cancer and would use the weekly regimen for women with TNBC who are at high risk,” Dr. Loibl said.

The study was limited by an imbalance of tumor subtypes between the treatment groups. The authors wrote that the results should guide further research, but nab-paclitaxel should not currently be viewed as a standard neoadjuvant treatment of breast cancer.

The study was funded by the German Breast Group, Bristol Myers Squibb, and Amgen. Dr. Loibl has served on the advisory boards or given lectures for AbbVie, Amgen, Bayer, Celgene, EirGenix, GSK, Lilly, Merck, Puma, Seagen, AstraZeneca, Daiichi Sankyo, Novartis, Pierre Fabre, Prime/Medscape, Bristol Myers Squibb, Chugai, Ipsen, Roche, and Samsung.

Uterine cancer mortality is highest in Black women

Article Type
Changed
Thu, 12/15/2022 - 14:31

A cohort study has found increases in mortality rates among women with non-endometrioid uterine carcinoma, despite incident rates that have stabilized. After correction with hysterectomy, mortality risk was about doubled for Black women, compared with White women, and these results could not be explained by differences in cancer subtype or cancer stage at diagnosis. Non-endometroid uterine carcinoma represents 15%-20% of uterine cancers diagnosed and carries a worse prognosis.

“We do not know why non-endometrioid subtypes are disproportionately increasing among all women, nor do we understand why they are so much more common among non-Hispanic Black women. We need more research to identify risk factors and exposures more specifically associated with non-endometrioid cancers to better understand the strong increases in this subtype among all women and the particularly high rates and recent increases in non-Hispanic black women,” said lead author Megan Clarke, PhD, MHS, the study’s lead author and a cancer epidemiologist with the National Cancer Institute.

The study was published online in JAMA Oncology.

“Physicians should be aware that both incidence and mortality rates of non-endometrioid cancers are on the rise. Because these subtypes are rarer than endometrioid uterine cancers, physicians may be less familiar with diagnosing and treating these aggressive types of cancers. Increasing awareness among clinicians and patients regarding the signs and symptoms of uterine cancer (such as postmenopausal bleeding) and the differences in histologic subtypes among racial and ethnic groups may promote earlier diagnosis and timely referral to appropriate treatment,” Dr. Clarke said.

Previous studies based on death certificates found increased mortality, especially in Black women, but they were limited by an inability to link mortality to tumor characteristics. To address this, the researchers linked mortality data to records of 208,587 women diagnosed with uterine cancer between 2000 and 2017, drawn from the U.S. Surveillance, Epidemiology, and End Results (SEER) Program.

Black women represented 9.7% of cases, but they suffered 17.7% of uterine cancer deaths. Overall, mortality from uterine corpus cancer increased by 1.8% per year (95% confidence interval, 1.5%-2.9%). Non-endometroid cancers increased at 2.7% per year (95% CI, 1.8%-3.6%), and this was higher in Asian (3.4%; 95% CI, 0.3%-6.6%), Black (3.5%; 95% CI, 2.2%-4.9%), Hispanic (6.7%; 95% CI, 1.9%-11.8%), and White women (1.5%; 95% CI, 0.6%-2.4%).

Mortality increased 1.8% per year overall for uterine cancer and 2.7% per year for non-endometrioid uterine cancer. There was no increase in mortality seen in endometrioid cancers.

“The concerning rise in deaths from non-endometrioid cancers warrants clinical attention. Our findings suggest that there may be several factors contributing to racial disparities in uterine cancer mortality. Higher mortality rates among non-Hispanic Black women are partly attributable to higher incidence of tumors with aggressive subtypes and advanced stages. However, non-Hispanic Black women in our study who were diagnosed with less aggressive subtypes and early-stage disease also had the highest mortality rates,” said Dr. Clarke.

That suggests that inequities of treatment and high-quality care may be at least partly to blame, since those factors are known to contribute to differences in uterine cancer outcomes. “Other factors including comorbidities, health care facility characteristics, treatment preferences and adherence, patient and provider communication, provider bias, discrimination and structural racism, and potential biologic differences in response to treatment need to be better understood in terms of how they influence racial disparities,” Dr. Clarke said.

Dr. Clarke reported no relevant disclosures.

Race-, ethnicity-based clinical guidelines miss the mark: Study

Article Type

Tue, 05/31/2022 - 14:04

– Race-based recommendations and clinical algorithms may be doing more harm than good, according to a systematic review of databases and guidelines.

The study found examples of screening recommendations based on race or ethnicity that were likely misleading since these are social constructs that don’t reflect a patient’s individual risk, said Shazia Siddique, MD, who presented the study at the annual Digestive Disease Week® (DDW). “Historically, we’ve made so many clinical decisions based on somebody’s race and ethnicity. We walk into a room, we don’t even ask people which racial or ethnic category they identify with. We just look at them and we say, ‘Their skin color looks black, and therefore we’re going to apply a different equation to them.’ ”

However, a patient’s risks and unique health circumstances are much more complicated than that. They may be related to genetics, or environmental exposures, or level of access to quality health care. Race can often be inappropriately used as a stand-in for these and other factors, she explained.

“These [racial] categories are truly a social construct. It’s becoming very problematic that people are literally making decisions based on somebody’s skin color. That’s just not what the science supports. If there are specific genes or environmental factors, or differences in access to health care that then impact outcomes for certain racial or ethnic groups, we need to figure out what those are,” said Dr. Siddique, who is an assistant professor of medicine at the University of Pennsylvania, Philadelphia.

Those messages are still entrenched in medical education. “I graduated medical school in 2012, and it was taught to me to use race and ethnicity in clinical decision-making. We need to start in medical education to shift the way that we’re thinking. On the research side, we really need to think about how we can replace or remove race and ethnicity and understand the consequences of that, so that over time we can make a shift,” said Dr. Siddique.

For example, Dr. Siddique discussed recommendations that suggest Asian heritage as a risk factor for hepatitis B screening, but that’s not a good factor to consider: “People were saying that Asians should be screened at an earlier age, but it’s really people that were born and raised in Asian countries where it’s endemic or they may have gotten it from their mothers at birth. It’s a marker for how long you have had the disease and how much virus is in your bloodstream. It’s not because you’re Asian. If you’re born and raised in the United States, and you don’t have any of those risk factors, you shouldn’t be treated differently based on your identified racial and ethnic group,” said Dr. Siddique.

These questions have become even more important in recent years because of patients with multiracial identifies and other considerations. “Now the proxy for which race was being used is even messier,” said Dr. Siddique.

So, how should physicians think about assessing a patient’s personalized risks? The key, said Dr. Siddique, is to look at each patient’s individual factors, such as health care access, environmental exposures from jobs or living conditions, or the country they emigrated from if they weren’t born in the United States. “Disease prevalences are different in different areas, and that changes your index of suspicion,” she said.

And when considering current guidelines that incorporate race or ethnicity, she recommends viewing them skeptically: “If there is a current algorithm in your health system or in a guideline that you’re reading that says you should be making a change based on race and ethnicity, you should look at that with a close eye and say, “What do I think it’s being used as a proxy for, and how can I elicit that from my patient?’ ”

The issues raised by Dr. Siddique’s study are important, but there also could be concerns in taking them too far, according to Gary Falk, MD, a professor of medicine at the University of Pennsylvania who comoderated the session where Dr. Siddique presented. He was not involved in the study, but was listed on Dr. Siddique’s acknowledgement slide.

Dr. Falk coauthored Barrett’s esophagus guidelines in 2016 that incorporated White race as a risk factor.

“There are certain clear ethnic factors or country of origin factors that impact one’s risk for cancer, and there are certain diseases that are more common in certain ethnic groups. I think that if we homogenize everybody, we may potentially hurt some people in the effort to be inclusive. That’s my only concern. I think it’s totally correct that we have to get out of our comfort zone, but I hate to see us reach too far on the other end, and homogenize things to the point that people who have increased risk are not being recognized for that reason,” said Dr. Falk.

He acknowledged that White race as a risk for Barrett’s is not easy to define given the uncertainty of the genetic risk, for example, in patients with mixed heritage. “This is all very provocative. We have to think about it carefully,” said Dr. Falk.

Dr. Siddique and Dr. Falk have no relevant financial disclosures.

Dr. Siddique and Dr. Falk have no relevant financial disclosures.

– Race-based recommendations and clinical algorithms may be doing more harm than good, according to a systematic review of databases and guidelines.

The study found examples of screening recommendations based on race or ethnicity that were likely misleading since these are social constructs that don’t reflect a patient’s individual risk, said Shazia Siddique, MD, who presented the study at the annual Digestive Disease Week® (DDW). “Historically, we’ve made so many clinical decisions based on somebody’s race and ethnicity. We walk into a room, we don’t even ask people which racial or ethnic category they identify with. We just look at them and we say, ‘Their skin color looks black, and therefore we’re going to apply a different equation to them.’ ”

However, a patient’s risks and unique health circumstances are much more complicated than that. They may be related to genetics, or environmental exposures, or level of access to quality health care. Race can often be inappropriately used as a stand-in for these and other factors, she explained.

“These [racial] categories are truly a social construct. It’s becoming very problematic that people are literally making decisions based on somebody’s skin color. That’s just not what the science supports. If there are specific genes or environmental factors, or differences in access to health care that then impact outcomes for certain racial or ethnic groups, we need to figure out what those are,” said Dr. Siddique, who is an assistant professor of medicine at the University of Pennsylvania, Philadelphia.

Those messages are still entrenched in medical education. “I graduated medical school in 2012, and it was taught to me to use race and ethnicity in clinical decision-making. We need to start in medical education to shift the way that we’re thinking. On the research side, we really need to think about how we can replace or remove race and ethnicity and understand the consequences of that, so that over time we can make a shift,” said Dr. Siddique.

For example, Dr. Siddique discussed recommendations that suggest Asian heritage as a risk factor for hepatitis B screening, but that’s not a good factor to consider: “People were saying that Asians should be screened at an earlier age, but it’s really people that were born and raised in Asian countries where it’s endemic or they may have gotten it from their mothers at birth. It’s a marker for how long you have had the disease and how much virus is in your bloodstream. It’s not because you’re Asian. If you’re born and raised in the United States, and you don’t have any of those risk factors, you shouldn’t be treated differently based on your identified racial and ethnic group,” said Dr. Siddique.

These questions have become even more important in recent years because of patients with multiracial identifies and other considerations. “Now the proxy for which race was being used is even messier,” said Dr. Siddique.

So, how should physicians think about assessing a patient’s personalized risks? The key, said Dr. Siddique, is to look at each patient’s individual factors, such as health care access, environmental exposures from jobs or living conditions, or the country they emigrated from if they weren’t born in the United States. “Disease prevalences are different in different areas, and that changes your index of suspicion,” she said.

And when considering current guidelines that incorporate race or ethnicity, she recommends viewing them skeptically: “If there is a current algorithm in your health system or in a guideline that you’re reading that says you should be making a change based on race and ethnicity, you should look at that with a close eye and say, “What do I think it’s being used as a proxy for, and how can I elicit that from my patient?’ ”

The issues raised by Dr. Siddique’s study are important, but there also could be concerns in taking them too far, according to Gary Falk, MD, a professor of medicine at the University of Pennsylvania who comoderated the session where Dr. Siddique presented. He was not involved in the study, but was listed on Dr. Siddique’s acknowledgement slide.

Dr. Falk coauthored Barrett’s esophagus guidelines in 2016 that incorporated White race as a risk factor.

“There are certain clear ethnic factors or country of origin factors that impact one’s risk for cancer, and there are certain diseases that are more common in certain ethnic groups. I think that if we homogenize everybody, we may potentially hurt some people in the effort to be inclusive. That’s my only concern. I think it’s totally correct that we have to get out of our comfort zone, but I hate to see us reach too far on the other end, and homogenize things to the point that people who have increased risk are not being recognized for that reason,” said Dr. Falk.

He acknowledged that White race as a risk for Barrett’s is not easy to define given the uncertainty of the genetic risk, for example, in patients with mixed heritage. “This is all very provocative. We have to think about it carefully,” said Dr. Falk.

Eosinophilic diseases often overlap, raising costs

Eosinophilic GI diseases (EGIDs) often overlap with other eosinophil-associated diseases (EADs), which leads to greater health care costs, according to an analysis of the U.S. Optum Clinformatics claims database.

EADs have gained increased attention in recent years. They include eosinophilic esophagitis (EoE), eosinophilic asthma, bullous pemphigoid, eosinophilic granulomatosis with polyangiitis, eosinophilic gastritis/gastroenteritis (EG/EGE), and a subset of non–cystic fibrosis bronchiectasis. All involve infiltration of eosinophils, but the exact immune mechanisms behind them seem to vary and are poorly understood, according to Justin Kwiatek, PharmD, who presented the results at the annual Digestive Disease Week® (DDW).

“We do know that the suitable course of treatment is dependent on the organs impacted. From this study, we also know that EoE mostly exists on its own, with only a small portion also being diagnosed with asthma, while overlap with other EGIDs tends to be higher. This could be because EoE appears to be pathologically different from other EGIDs in the gastrointestinal tract such as eosinophilic gastritis in the stomach or eosinophilic gastroenteritis in the stomach and small bowel. Eosinophils are not normally present in the esophagus but are often found in the stomach or small bowel without inflammation,” said Dr. Kwiatek, who is senior global medical affairs leader, respiratory & immunology, at AstraZeneca.

The study is important, said Dhyanesh Patel, MD, who was asked to comment on the study. “There’s been a lot of interest in eosinophilic gastrointestinal diseases recently because there is lack of a clear definition. We need to define it better because we need to figure out treatment options for the patients,” said Dr. Patel, who is an assistant professor of medicine at Vanderbilt University, Nashville, Tenn.

“It highlights that a lot of the patients that have one eosinophilic disease might have other concomitant atopic diseases. [It may be that] you can use one drug to treat all of them together, so I think it’s important to have a multidisciplinary approach where you work with an allergist and you work with an immunologist and treat their eosinophilic gastritis and their asthma together with one drug. That may help reduce medication burden,” said Dr. Patel.

The researchers analyzed records from 1,326,645 diagnosed patients with at least one EAD and at least 2 years following treatment. There were 13,872 patients with EoE, 38.4% of whom had at least one overlapping EAD. Of 1,365 patients with EG/EGE, 57.9% had at least one overlapping EAD.

EADs were associated with higher Charlson Comorbidity Index scores and high blood eosinophil levels (≥ 300 cells/mcL) among EoE patients, but not among EG/EGE patients. Within the EoE group, female gender was linked to more EAD comorbidities: 35% of patients with only EoE were female; 45% of patients with one comorbidity were female, as were 55% of those with two comorbidities and 57% of those with three or more comorbidities. There was no such trend among patients with EG/EGE.

Total health care costs were lower in the absence of one overlapping EAD among both EoE ($2,061 vs. $3,766 per patient per month) and EG/EGE patients ($2,860 vs. $4,053). Costs went up with more overlap: $8,572 for EoE and three or more other EADs, and $10,397 for EG/EGE and three or more other EADs. These costs were largely driven by outpatient care.

“The data shows that patients with eosinophilic gastritis and eosinophilic gastroenteritis are more likely to have overlapping eosinophilic conditions, such as asthma. When diagnosing a patient with EG or EGE, it’s important to monitor any new symptoms closely and to educate them about the risk factors. This is particularly true for patients with elevated blood eosinophil counts. Accounting for comorbidities and establishing a treatment plan early can help to manage the higher health care spend for patients with overlapping conditions,” said Dr. Kwiatek.

Dr. Kwiatek is an employee and stockholder of AstraZeneca, which funded the study and developed benralizumab, a drug that has been granted orphan drug status for EG/EGE and EoE. Optum Clinformatics is a longitudinal database of deidentified data formed by UnitedHealth Group. Dr. Patel has no relevant financial disclosures.

ESG’s cardiometabolic benefits last 5 years

– Endoscopic sleeve gastroplasty (ESG) led to sustained weight loss and a reduction of cardiometabolic syndrome comorbidities at 5 years, according to a new retrospective analysis of prospectively collected data.

Improved cardiometabolic outcomes following bariatric surgery have been well documented, but ESG is relatively new, so its outcomes haven’t been as well described. The outcomes are encouraging, though not as good as those of bariatric surgery. “It’s still better, but only one percent of the patients undergo the surgery, even though they’re candidates,” said Donevan Westerveld, MD, who presented the study at the annual Digestive Disease Week® (DDW).

Improvements included weight, HbA1c percentage, hypertension, and low-density lipoprotein. “I was surprised that the LDL decreased numerically, not so much HbA1c and hypertension. I knew [those] would come down with weight loss,” said Dr. Westerveld, a second-year fellow at Weill Cornell Medicine, New York.

He also called for guidelines for ESG. “Given the fact there’s an improvement of comorbid conditions, it’s something we should look at,” said Dr. Westerveld.

“It’s fascinating because it tells us two important things about endoscopic sleeve gastroplasty. One, [the benefit] in the majority of cases lasts at least 5 years. The weight loss is durable. And then it tells us that there’s improvement in all the cardiometabolic factors that matter, and those effects are seen all the way up to 5 years. So very important findings that support the benefits of the endoscopic gastroplasty in obesity and cardiometabolic risks and metabolic syndrome,” said Andres Acosta, MD, PhD, a comoderator of the session where the study was presented. He is assistant professor of medicine and a consultant in gastroenterology and hepatology at Mayo Clinic in Rochester, Minn.

The findings should also encourage more innovation. “Doing these endoscopic procedures, having successful results that hold for 5 years, opens the path for new and better procedures, so we have better weight loss,” said Dr. Acosta.

Previous work by Dr. Westerveld’s group found benefits of ESG at 12 months, including improvements in mean HbA1c levels in all patients (6.1%-5.5%; P = .05) and those with diabetes or prediabetes (6.6%-5.6%; P = .02), reduction in mean waist circumference (119.66-92.75 cm; P < .001), reduction in systolic blood pressure (129.02-122.23 mg/dL; P = .023), triglycerides (131.84-92.36 mg/dL; P = .017), and alanine aminotransferase (ALT, 32.26-20.68 mg/dL; P < .001).

In the new study, the group followed 255 patients at 1, 3, and 5 years post procedure who were treated consecutively at Weill Cornell Medicine from 2013 to 2021. Among the patients were those who had failed weight loss measures and were either not candidates for surgery or had refused surgery.

The mean age was 45.5 years, 69% were female, and the mean body mass index was 38.6. Overall, 40.3% had prediabetes or diabetes, 26.7% had hypertension, 60.8% had low-density lipoprotein (LDL) above 100 mg/dL, and 29.3% had elevated ALT. Sixty-six percent had been followed up at 1 year, 78% at 3 years, and 87% at 5 years.

Weight loss averaged 15.7% at 1 year and 15.3% at year 5, and the values were statistically significant. Among patients with diabetes and prediabetes, HbA1c percentage dropped from a baseline value of 6.4% to 5.7% at year 1, 6.1% at year 3, and 5.8% at year 5 (P < .05 for all). For all patients, the value dropped from 5.8% at baseline to 5.6% at year 1, 5.7% at year 3, and 5.4% at year 5. These changes were not statistically significant.

Systolic blood pressure went down among patients with stage 1 hypertension, from 135 mm Hg at baseline to 122 at year 1 and 121 at year 3 (P < .05 or both), but the mean value increased to 129 at year 5 and was not statistically significant. LDL among all patients declined from 136 mg/dL at baseline to 125 at year 1 (nonsignificant), 115 at year 3 (P < .05), and 109 at year 5 (P < .05). Alanine transaminase values declined from about 29 at baseline to 25 at year 1, 26 at year 3, and 24 at year 5 (P < .05 for all).

Serious adverse events were rare, occurring in just two cases (< 1%).

The study was limited by lack of a sham control, and its retrospective data may have included bias because many of the procedures were not paid for by insurance, leading to high rates of self-pay.

The mean age was 45.5 years, 69% were female, and the mean body mass index was 38.6. Overall, 40.3% had prediabetes or diabetes, 26.7% had hypertension, 60.8% had low-density lipoprotein (LDL) above 100 mg/dL, and 29.3% had elevated ALT. Sixty-six percent had been followed up at 1 year, 78% at 3 years, and 87% at 5 years.

Weight loss averaged 15.7% at 1 year and 15.3% at year 5, and the values were statistically significant. Among patients with diabetes and prediabetes, HbA1c percentage dropped from a baseline value of 6.4% to 5.7% at year 1, 6.1% at year 3, and 5.8% at year 5 (P < .05 for all). For all patients, the value dropped from 5.8% at baseline to 5.6% at year 1, 5.7% at year 3, and 5.4% at year 5. These changes were not statistically significant.

Systolic blood pressure went down among patients with stage 1 hypertension, from 135 mm Hg at baseline to 122 at year 1 and 121 at year 3 (P < .05 or both), but the mean value increased to 129 at year 5 and was not statistically significant. LDL among all patients declined from 136 mg/dL at baseline to 125 at year 1 (nonsignificant), 115 at year 3 (P < .05), and 109 at year 5 (P < .05). Alanine transaminase values declined from about 29 at baseline to 25 at year 1, 26 at year 3, and 24 at year 5 (P < .05 for all).

Serious adverse events were rare, occurring in just two cases (< 1%).

The study was limited by lack of a sham control, and its retrospective data may have included bias because many of the procedures were not paid for by insurance, leading to high rates of self-pay.

Vibrating pill counters constipation

Article Type

Wed, 05/25/2022 - 10:37

A swallowable, vibrating capsule improved symptoms among patients with chronic idiopathic constipation in a phase 3 multicenter, randomized, controlled trial. The method represents a mechanical approach to the treatment of constipation.

The swallowable pill acts by vibrating during passage through the gut, where it is thought to augment colonic biorhythm and peristalsis. Traditional treatments for constipation generally increase motility or secretion.

“That’s how we have been managing constipation since time immemorial. Now we have come up with this novel approach, where there’s a pill that is designed to increase local oscillations, and probably induce local contractions of the colon to mimic what happens normally,” said Satish Rao, MD, PhD, who presented the results of the trial at the annual Digestive Disease Week® (DDW).

“We’re now seeing that local stimulation works, and the other neat thing seems to be a lack of side effects, which is really a huge plus. I think it will benefit people with both occasional or chronic constipation,” said Dr. Rao, professor of medicine at Medical College of Georgia, Augusta.

The capsules activate for two stimulation cycles, each lasting for about 2 hours. The cycle includes 3 seconds of vibration followed by 16 seconds of rest.

The researchers conducted a study with two active arms and a placebo. It included 312 patients age 22 or older who had an average of between 1 and 2.5 spontaneous bowel movements (SBM) per week.

Treatment lasted for 8 weeks, with patients ingesting a capsule between 9 and 10 p.m. In one treatment group, the device was activated at 6 a.m., and in the other group at about 2 p.m.

The placebo and treatment groups had similar baseline characteristics, except for a longer duration of constipation in the treatment groups (17.9 versus 14.5 years; P = .0253). In an intention-to-treat analysis, the treatment groups were more likely to achieve an increase of one complete SBM per week (39.26% versus 22.15%; P < .0001) and an increase of two complete SBMs per week (22.7% versus 11.41%; P < .0006).

The capsules also improved straining score, stool consistency, and quality of life. There was no significant difference between treatment and placebo groups with respect to bloating or rescue medication use.

The product had few adverse effects. The most common was a vibrating sensation or discomfort (11.0%, versus none in the placebo group).

Dr. Rao expects that the treatment could be widely applicable since many constipation patients don’t gain sufficient benefit from existing treatments, or find side effects intolerable.

Another benefit is that the therapy’s mimicry of natural cycles appears to grant patients more control of bowel movements. Laxatives and other pharmaceutical interventions may prompt the patient to go to the bathroom within an hour or two, but patients in the trial reported bowel movements at predictable times.

However, he noted that the pill is nondissolvable, which would make it contraindicated for patients who have had previous gut surgeries or narrowing of the gut. He noted that the sponsoring company, Vibrant Gastro, expects to obtain Food and Drug Administration approval by the end of 2022.

The results of the study were well received. “I think it’s an exciting new approach for managing patients with chronic constipation. It was a large sample size, and the treatment seems to be well tolerated. It may offer a promising option for patients who have not responded to many other medications,” said Adil E. Bharucha, MD, who comoderated the session where the research was presented.

However, he pointed out that the presentation did not indicate how many of the patients had previously tried other therapies. “We’d like to see the full paper, which will provide a better understanding of the role of this treatment in practice down the road,” said Dr. Bharucha, professor of medicine in the division of gastroenterology and hepatology and director of the office of clinical trials at Mayo Clinic, Rochester, Minn.

The capsule may not work for everyone, said Dr. Bharucha. He suspects that many refractory patients have an issue with pelvic floor muscles, which may restrict stool evacuation. “You wouldn’t expect those people to respond optimally to a laxative and I suspect perhaps not to a capsule, either. I think defecatory disorders are substantially underdiagnosed in patients who don’t respond to laxatives,” said Dr. Bharucha.

Asked why the capsule might benefit patients who don’t improve with laxatives, Dr. Bharucha responded: “I think we need more studies to understand how the capsule works.”

Sex hormones linked to breast cancer in men

Article Type

Fri, 12/16/2022 - 10:07

Male breast cancer is linked to infertility, according to a new case-control study from the Institute of Cancer Research in London. The report follows other studies that generally failed to identify a statistically significant association, but the resources of Great Britain’s National Health Service made it possible to achieve greater power than previous efforts.

“It’s a very difficult disease to study because it’s about 100 times rarer than female breast cancer. To do the equivalent study, you either have to make your study 100 times bigger, or think laterally and approach it a different way. (That’s) why we did a case control study where you identify the cases and find controls, rather than wait for men to develop breast cancer,” said Michael Edwin Jones, PhD, the lead author of the study, which was published online in Breast Cancer Research.

The new study found that men who self-reported infertility had a doubled risk of breast cancer, while there was no difference if the fertility was linked to their female partner. Sex hormones are known to play a key role in female breast cancer, and they have a suspected role in male breast cancer as well, though it’s hard to pin down because there is no concentrated source of exposure like hormone therapy or activity from the ovary to cause spiked levels. “It’s more subtle in men, but there’s a reason to think it’s important,” Dr. Jones said.

Although the results hint at a possible role of sex hormones, the research can’t confirm that. Blood draws were taken from participants, but many were conducted after treatment had begun, leading to inconsistent results. Dr. Jones called for more research into biological mechanisms that might explain the increased risk, and suggested that such efforts could lead to a better understanding of breast cancer overall, since the disease in men is not effected by factors like pregnancy and menopause.

Historically, few clinical trials for breast cancer drugs included men, and this has resulted in few approved treatments. However, the impact of breast cancer on men is increasingly being recognized, and most such trials now accept male patients. The Food and Drug Administration has even produced a guidance document for inclusion of men in development of breast cancer drugs, which states that men should be excluded only if there is a clear scientific rationale. When there are too few male participants to draw direct conclusions, it may be possible to extrapolate findings in women to men for FDA approval, provided the mechanism of action suggests that there should be no difference in efficacy.

The Breast Cancer Now study included 1,998 cases and 1,597 controls, who were asked about infertility and whether they had children. Men with male-origin infertility had a higher risk of breast cancer (odds ratio, 2.03; 95% confidence interval [CI], 1.18-3.49), but not men who reported female-origin infertility (OR, 0.86; 95% CI, 0.51-1.45). There was also a heightened risk among men who had not fathered children versus those who had (OR, 1.50; 95% CI, 1.21-1.86).

The association was statistically significant for invasive tumors (OR, 1.96; P = .02), but only a trend was observed for in situ breast cancer (OR, 1.72; P = .39). A possible explanation is that diagnosis of in situ breast cancer is less common than invasive cancer in men, which could have led to the study being underpowered. “Unfortunately, there were too few in-situ breast cancers to allow us to say anything definitive,” said Dr. Jones.

Dr. Jones has no relevant financial disclosures. The study was funded by Breast Cancer Now.

PI-based DAAs appear safe in decompensated patients

Article Type

Wed, 05/25/2022 - 10:58

 

– An analysis of a large, international cohort suggests that treatment with protease-inhibitor (PI)–based direct-acting antivirals (DAAs) may be safe for patients with hepatitis C virus (HCV) with cirrhosis and early-stage liver decompensation.

The study relied on data from the REAL-C registry, including 935 patients treated with oral DAAs at 27 centers in the U.S., Europe, and Asia Pacific countries. The researchers compared efficacy and tolerability outcomes from PI-based and non PI-based DAA regimens in patients deemed to have decompensated HCV cirrhosis.

The findings were encouraging. “It is something important because currently we are short of treatments for decompensated HCV patients. If the tolerability is similar, we perhaps should not withhold [PI] treatment for these patients that sometimes need them the most,” said Yu Jun Wong, MD, who presented the study at the annual Digestive Disease Week® (DDW). Dr. Wong is a second-year consultant at Changchi General Hospital in Singapore.

“I think it was a very interesting study and something that needed to be done. It was encouraging that patients who did have some level of decompensated cirrhosis did not worsen compared to those who were on a non PI-based therapy,” said Meena Bansal, MD, who comoderated the session where the research was presented.

However, the study was limited by some uncertainty around the definition of decompensation among the study participants. During the Q&A session, audience members questioned whether patients categorized as decompensated were truly decompensated at the time of treatment initiation. Dr. Bansal noted, for example, that a patient might experience a variceal bleed in the context of heavy alcohol consumption, and therefore be considered decompensated, but might stop drinking afterward with a reduction in portal hypertension and recovery of liver function. “So it would be important to know if they were still decompensated at the time they initiated therapy. If that was the case, then these results are more promising,” said Dr. Bansal.

Despite these limitations, the study is good news. “If you do not have access to non-PI based therapy, you might feel a little bit more secure starting a PI-based therapy, particularly the second generation PI-based therapies, if they’re at least on the earlier side of that decompensation scale. But it’s still unclear in true decompensated Child’s B or C whether or not PI-based therapy would have the same results,” said Dr. Bansal.

Dr. Wong acknowledged the limitation that the study doesn’t apply to more severely decompensated patients. “Whether it remains safe in patients with higher Child-Pugh scores is hard to extrapolate at this point of time. We still need to look further into the data,” said Dr. Wong.

Still, the results offer hope to physicians and patients who might find themselves in difficult circumstances. “If you’re resource limited, and you don’t even have access to transplant, these findings suggest that early decompensated patients may benefit from PI-based therapy. If I say to the patient, there’s a chance this could make you worse, but there’s a chance this could make you better, [this is an option] as long as the patient is aware of the possible outcomes,” said Dr. Bansal.

The study included patients with a history of ascites, variceal bleeding, jaundice, or hepatic encephalopathy 6 months before treatment with DAA, or baseline measures of Child-Turcotte-Pugh (CTP) score ≥7 or Model of End-Stage Liver Disease (MELD) score >10. The analysis included data between 2014 and 2021.

The mean age was 64, and 59.6% of participants were male. Overall, 70.8% had genotype 1, and 32% were treatment experienced. In total, 45.2% were treated with PI-based DAAs.

The PI cohort was older (64.6 versus 62.7; P = .01), and more likely to have genotype 1 (87.2% versus 56.3%; P < .001) and chronic renal disease (64.0% vs. 53.9%; P = .001).

The two groups had similar rates of sustained virologic response at 12 and 24 weeks, as well as similar rates of significant improvement or significant worsening, suggesting similar tolerability. There was a lower frequency of liver decompensation in the PI group at 12 weeks (4.4% vs. 7.9%; P = .04) and a trend at 24 weeks (8.8% versus 12.6%; P = .08).

Another limitation of the study is the potential for bias due to its retrospective nature.

Dr. Wong has been an invited speaker for AbbVie and Gilead. Dr. Bansal has no relevant financial disclosures.

The study relied on data from the REAL-C registry, including 935 patients treated with oral DAAs at 27 centers in the U.S., Europe, and Asia Pacific countries. The researchers compared efficacy and tolerability outcomes from PI-based and non PI-based DAA regimens in patients deemed to have decompensated HCV cirrhosis.

The findings were encouraging. “It is something important because currently we are short of treatments for decompensated HCV patients. If the tolerability is similar, we perhaps should not withhold [PI] treatment for these patients that sometimes need them the most,” said Yu Jun Wong, MD, who presented the study at the annual Digestive Disease Week® (DDW). Dr. Wong is a second-year consultant at Changchi General Hospital in Singapore.

“I think it was a very interesting study and something that needed to be done. It was encouraging that patients who did have some level of decompensated cirrhosis did not worsen compared to those who were on a non PI-based therapy,” said Meena Bansal, MD, who comoderated the session where the research was presented.

However, the study was limited by some uncertainty around the definition of decompensation among the study participants. During the Q&A session, audience members questioned whether patients categorized as decompensated were truly decompensated at the time of treatment initiation. Dr. Bansal noted, for example, that a patient might experience a variceal bleed in the context of heavy alcohol consumption, and therefore be considered decompensated, but might stop drinking afterward with a reduction in portal hypertension and recovery of liver function. “So it would be important to know if they were still decompensated at the time they initiated therapy. If that was the case, then these results are more promising,” said Dr. Bansal.

Despite these limitations, the study is good news. “If you do not have access to non-PI based therapy, you might feel a little bit more secure starting a PI-based therapy, particularly the second generation PI-based therapies, if they’re at least on the earlier side of that decompensation scale. But it’s still unclear in true decompensated Child’s B or C whether or not PI-based therapy would have the same results,” said Dr. Bansal.

Dr. Wong acknowledged the limitation that the study doesn’t apply to more severely decompensated patients. “Whether it remains safe in patients with higher Child-Pugh scores is hard to extrapolate at this point of time. We still need to look further into the data,” said Dr. Wong.

Still, the results offer hope to physicians and patients who might find themselves in difficult circumstances. “If you’re resource limited, and you don’t even have access to transplant, these findings suggest that early decompensated patients may benefit from PI-based therapy. If I say to the patient, there’s a chance this could make you worse, but there’s a chance this could make you better, [this is an option] as long as the patient is aware of the possible outcomes,” said Dr. Bansal.

The study included patients with a history of ascites, variceal bleeding, jaundice, or hepatic encephalopathy 6 months before treatment with DAA, or baseline measures of Child-Turcotte-Pugh (CTP) score ≥7 or Model of End-Stage Liver Disease (MELD) score >10. The analysis included data between 2014 and 2021.

The mean age was 64, and 59.6% of participants were male. Overall, 70.8% had genotype 1, and 32% were treatment experienced. In total, 45.2% were treated with PI-based DAAs.

The PI cohort was older (64.6 versus 62.7; P = .01), and more likely to have genotype 1 (87.2% versus 56.3%; P < .001) and chronic renal disease (64.0% vs. 53.9%; P = .001).

The two groups had similar rates of sustained virologic response at 12 and 24 weeks, as well as similar rates of significant improvement or significant worsening, suggesting similar tolerability. There was a lower frequency of liver decompensation in the PI group at 12 weeks (4.4% vs. 7.9%; P = .04) and a trend at 24 weeks (8.8% versus 12.6%; P = .08).

Another limitation of the study is the potential for bias due to its retrospective nature.

Dr. Wong has been an invited speaker for AbbVie and Gilead. Dr. Bansal has no relevant financial disclosures.

Bacterial cocktail, spores counter recurrent C. diff

 

– A novel combination of eight human commensal bacteria has shown efficacy in preventing recurrent Clostridioides difficile infections in high-risk populations. The cocktail of bacterial strains (VE303), produced under tightly-controlled conditions, is delivered in powdered form over a period of 14 days.

The approach, sponsored by Vedanta Biosciences, is one of several efforts to use carefully defined microbial populations instead of fecal microbiota transplantation (FMT) to treat or prevent C. diff infections.

The key issue is that not all of the bacteria found in FMTs are needed to provide a therapeutic effect, according to Thomas Louie, MD, professor of medicine at the University of Calgary (Alta.). “You don’t need all the bugs. You don’t need raw [stool]. You can take only the good parts,” said Dr. Louie, who presented the results of the phase 2 study at the annual Digestive Disease Week® (DDW). In fact, FMT carries the risk of infection of pathogenic bacteria.

The strains found in VE303 were consistently identified in patients’ microbiota following successful FMTs, though they were absent before the transplant. Animal and human studies then showed that the microbes could repopulate microbiota.

Among 78 patients included in the efficacy analysis of the study, after 8 weeks, 13.8% of the VE303 group experienced a recurrent C. diff infection, versus 45.5% of the placebo group, amounting to more than an 80% reduction in risk (odds ratio, 0.192; P = .0077). Adverse events were mild and similar across both groups, with no treatment-related serious adverse events reported.

The same session included a post hoc analysis of a phase 3 study sponsored by Seres Therapeutics, which showed that the company’s oral product SER-109, composed of purified Firmicutes spores, reduced the risk of recurrent C. diff infection after 8 weeks compared to placebo (12.4% versus 39.8%; P < .001).

The new analysis examined short-, medium-, and branch-chained fatty acids in patient stools. After just 1 week of treatment, there was an increase in the short-chain fatty acid butyrate and medium-chain fatty acids valerate and hexanoate. They continued to be higher in weeks 2 and 8 in the treatment arm. The results suggest that increased fatty acid production might boost clinical outcomes, according to Kevin Litcofsky of Seres, who presented the results.

Both approaches have potential, according to Melinda Engevik, PhD, who comoderated the session where the study was presented. “I think that they’re both interesting ideas. The spores [from Seres], I think, are going to be better at passing through the stomach and a little bit more resistant, but then they have to germinate and engraft, whereas if you give the lyophilized bacteria [from Vedanta], you might lose some more, but they’re already primed and ready to go. So I think they’re both very different approaches, but the data from both seem to support that they worked and probably in different ways,” said Dr. Engevik, assistant professor at the Medical University of South Carolina, Charleston.

“Patients that have recurrent [C. diff], they are desperate to be able to break the cycle of recurrence. I think that they’ve shown a lot of safety with this, which is an issue for FMT. Both of the talks seemed like there is a path moving forward to help those patients. I was encouraged,” said Dr. Engevik.

Comoderator Anoop Kumar, PhD, assistant professor of gastroenterology and hepatology at University of Illinois, Chicago, agreed and noted the advantage of such treatments over FMT during the COVID-19 pandemic, which has disrupted FMT delivery.

Previous studies have looked at probiotics, but results so far have been mixed, said Dr. Engevik. She suspects these two approaches, containing more bacterial strains, are likely to have better success. “I think you really have to have a complex gut microbiota community, at least minimally complex, to be able to get the effects. I think it’s the wave of the future,” she said.

Dr. Engevik also suggested that the benefits might not stop at C. diff. She highlighted research in other gastrointestinal diseases such as inflammatory bowel disease, and even efforts underway to enhance responses to checkpoint inhibitors in the treatment of cancer. “Gut microbes are master regulators, so they have these wide-reaching effects. I think that a lot of human health will be started to be targeted by looking at the gut microbiota,” she said.

Dr. Louie also highlighted the potential for more applications. “C. diff is low-hanging fruit. I think these bugs will have some usefulness for [irritable bowel syndrome]. I’ve transplanted some patients with IBS and it seemed to work. I haven’t had time to design and do an IBS trial, but the future is these bugs.”

Dr. Louie also participated in the Seres study. He has been on the advisory board for Vedanta, Seres, Finch Therapeutics, and Artugen Therapeutics. Dr. Engevik and Dr. Kumar have no relevant financial disclosures.

Steroid use associated with higher relapse risk in some UC

Article Type

Mon, 05/23/2022 - 09:31

Patients who have histologically active ulcerative colitis (UC) with a Mayo endoscopic subscore (MES) of 1 and a history of steroid use may be at increased risk for clinical relapse, according to a new single-center, retrospective analysis.

In recent years, treat-to-target approaches in UC have incorporated clinician and patient-reported outcomes, along with endoscopic remission, defined as MES 1 or less. However, additional studies showed a higher risk of relapse with MES 1, and the STRIDE-II (Selecting Therapeutic Targets in Inflammatory Bowel Disease) guidelines released in 2021 suggest that only MES 0 indicates endoscopic healing.

Nevertheless, there is concern that striving to achieve MES 0 could lead to overtreatment, since MES values are somewhat subjective, and patients with MES 1 sometimes report few or no symptoms. This led to the current study by Gyeol Seong, MD, and colleagues, published in Inflammatory Bowel Diseases.

Dr. Miguel Regueiro

Commenting on the study, Miguel Regueiro, MD, chair for the Digestive Disease and Surgery Institute and a professor of medicine at the Cleveland Clinic said “the question has always been, if the patient is in endoscopic remission and clinically feels well, how important is it to have histologically normal mucosa?”

In their retrospective study, Dr. Seong and colleagues analyzed data from 492 patients. The median age was 48, and 51.6% were male. The median duration of disease was 78 months. During a median follow-up of 549 days, 18.7% experienced a relapse, defined as “change or escalation of medication, hospitalization due to the aggravation of UC, or total colectomy.” Of these patients, 39.4% had used steroids and 51.4% had a MES score of 0 at the index endoscopy, and 70.5% had histologic improvement, as defined by a Geboes score of less than 3.1.

A Geboes score of 3.1 or higher and a history of steroid use was associated with an increased cumulative incidence of clinical relapse, compared with a Geboes score lower than 3.1 and no steroid use (P = .001). In a multivariate analysis, histologic activity alone was not a predictor of relapse. Among patients with an MES score of 1, a history of steroid use predicted risk of relapse (adjusted hazard ratio, 2.102; P = .006).

Although Dr. Regueiro said the new findings would not change his current practice, he does incorporate histopathology in clinical decision-making. In cases where a patient is in endoscopic remission but has histologic activity, he will consider adjusting the current medication rather than changing to a different therapeutic. “I wouldn’t recommend that we switch patients off one therapy to another just because of histologic activity.”

That’s because patients often improve dramatically after effective therapy. Dr. Regueiro said: “The one concern is whether the next medicine works as well as what the patient is already on? I’m also worried that we burn through our biologics too quickly. We go from one to another and another, sometimes I think we just need to optimize the one they’re on.”

The study does have the potential to influence surveillance for dysplasia, according to Dr. Regueiro, noting that a recent retrospective analysis showed an increased risk of dysplasia in UC with persistent histologic activity. “This suggests the need for a colonoscopy in a patient who has had ulcerative colitis for a number of years, even if there’s improvement but, on biopsy, there’s evidence of inflammation.”

According to Dr. Regueiro, such patients might benefit from a fecal calprotectin measurement in 3-6 months to monitor for colonic inflammation. Increased levels might be a sign that the patient is skipping medication doses, although other factors, like respiratory infections, can also explain the results. If the patient’s medication adherence is good, another therapy can be added or the dose increased, and the next endoscopy can be pushed up.

A key limitation to the study by Dr. Seong and colleagues is that it was based in South Korea. “Would this be the same in different countries and different populations? That is still a question,” said Dr. Regueiro.

Dr. Regueiro has received unrestricted educational grants from Abbvie, Janssen, UCB, Pfizer, Takeda, Celgene, Genentech, Gilead, Bristol-Myers Squibb, and Lilly. He has been on advisory boards or consulted for numerous companies. He also has relationships with the following CME companies: CME Outfitters, Imedex, GI Health Foundation, Cornerstones, Remedy, MJH Life Sciences, Medscape, MDEducation, WebMD, and HMPGlobal.

Patients who have histologically active ulcerative colitis (UC) with a Mayo endoscopic subscore (MES) of 1 and a history of steroid use may be at increased risk for clinical relapse, according to a new single-center, retrospective analysis.

In recent years, treat-to-target approaches in UC have incorporated clinician and patient-reported outcomes, along with endoscopic remission, defined as MES 1 or less. However, additional studies showed a higher risk of relapse with MES 1, and the STRIDE-II (Selecting Therapeutic Targets in Inflammatory Bowel Disease) guidelines released in 2021 suggest that only MES 0 indicates endoscopic healing.

Nevertheless, there is concern that striving to achieve MES 0 could lead to overtreatment, since MES values are somewhat subjective, and patients with MES 1 sometimes report few or no symptoms. This led to the current study by Gyeol Seong, MD, and colleagues, published in Inflammatory Bowel Diseases.

Dr. Miguel Regueiro

Commenting on the study, Miguel Regueiro, MD, chair for the Digestive Disease and Surgery Institute and a professor of medicine at the Cleveland Clinic said “the question has always been, if the patient is in endoscopic remission and clinically feels well, how important is it to have histologically normal mucosa?”

In their retrospective study, Dr. Seong and colleagues analyzed data from 492 patients. The median age was 48, and 51.6% were male. The median duration of disease was 78 months. During a median follow-up of 549 days, 18.7% experienced a relapse, defined as “change or escalation of medication, hospitalization due to the aggravation of UC, or total colectomy.” Of these patients, 39.4% had used steroids and 51.4% had a MES score of 0 at the index endoscopy, and 70.5% had histologic improvement, as defined by a Geboes score of less than 3.1.

A Geboes score of 3.1 or higher and a history of steroid use was associated with an increased cumulative incidence of clinical relapse, compared with a Geboes score lower than 3.1 and no steroid use (P = .001). In a multivariate analysis, histologic activity alone was not a predictor of relapse. Among patients with an MES score of 1, a history of steroid use predicted risk of relapse (adjusted hazard ratio, 2.102; P = .006).

Although Dr. Regueiro said the new findings would not change his current practice, he does incorporate histopathology in clinical decision-making. In cases where a patient is in endoscopic remission but has histologic activity, he will consider adjusting the current medication rather than changing to a different therapeutic. “I wouldn’t recommend that we switch patients off one therapy to another just because of histologic activity.”

That’s because patients often improve dramatically after effective therapy. Dr. Regueiro said: “The one concern is whether the next medicine works as well as what the patient is already on? I’m also worried that we burn through our biologics too quickly. We go from one to another and another, sometimes I think we just need to optimize the one they’re on.”

The study does have the potential to influence surveillance for dysplasia, according to Dr. Regueiro, noting that a recent retrospective analysis showed an increased risk of dysplasia in UC with persistent histologic activity. “This suggests the need for a colonoscopy in a patient who has had ulcerative colitis for a number of years, even if there’s improvement but, on biopsy, there’s evidence of inflammation.”

According to Dr. Regueiro, such patients might benefit from a fecal calprotectin measurement in 3-6 months to monitor for colonic inflammation. Increased levels might be a sign that the patient is skipping medication doses, although other factors, like respiratory infections, can also explain the results. If the patient’s medication adherence is good, another therapy can be added or the dose increased, and the next endoscopy can be pushed up.

A key limitation to the study by Dr. Seong and colleagues is that it was based in South Korea. “Would this be the same in different countries and different populations? That is still a question,” said Dr. Regueiro.
