SAN FRANCISCO – Influenza season is upon us, and Helen Chu, MD, MPH, is here at ID Week 2018 to talk vaccines, especially for pregnant women.

They are at greater risk for more severe illness, and influenza can lead to adverse outcomes in infants. The good news is that recent studies have shown that flu vaccines are safe and effective in pregnant women.

The bad news is that many women are hesitant to be vaccinated out of concerns over safety, in a trend that reflects broader societal worries over vaccination, said Dr. Chu, of the University of Washington, Seattle. In a video interview at an annual scientific meeting on infectious diseases, Dr. Chu advised steps to ensure that pregnant women are aware of the safety and efficacy of flu vaccines, and the benefits to the infant who acquires immunity through the mother. It’s also a good idea to have vaccine on hand to be able to offer it immediately during an office visit.

The Diagnosis: Terra Firma-Forme Dermatosis

Terra firma-forme dermatosis (TFFD), also known as Duncan dirty dermatosis, is an idiopathic benign cutaneous condition that is easily misdiagnosed or mismanaged. In 1987, Duncan et al1 first described the condition in children who had mothers that lamented over dirty skin spots that could not be washed off. The term terra firma translates in Latin to solid ground, which describes the characteristic dirtlike appearance of these lesions.

Terra firma-forme dermatosis most commonly affects children and young adults, though it can present in patients of any age without any known predisposing risk factors.^1-4 The lesions have a predilection for the face, neck, shoulders, trunk, and ankles. Terra firma-forme dermatosis has no association with bathing and hygiene habits, and most patients describe unsuccessful removal of the lesions, even after vigorous scrubbing with soaps and detergents at home. The lesions are asymptomatic, and many patients present to dermatology for cosmetic concerns.^1-8

The etiology of TFFD is not well understood and is considered a retention hyperkeratosis. Duncan et al¹ postulated that TFFD is the result of partial or improper maturation of keratinocytes leading to keratinocyte and melanin retention. Hematoxylin and eosin stains demonstrate lamellar hyperkeratosis of the stratum corneum without parakeratosis as well as keratin pearls scattered throughout. Mild acanthosis and papillomatosis also have been reported.^1,5-7 Fontana-Masson stain shows excess melanin in these lesions, extending from the basal layer to the stratum corneum. Fungal and bacterial stains as well as cultures often have no notable findings.^1,7 Similarly, histopathologic examination of our patient's biopsy with hematoxylin and eosin stain revealed hyperorthokeratosis with scattered naked vellus hair shafts and incidental yeast forms (Figure 1).

The differential diagnosis for TFFD may include pityriasis versicolor, confluent and reticulated papillomatosis, acanthosis nigricans, ichthyosis, malignant melanoma, and seborrheic keratosis. All of these diagnoses can be ruled out by the easy removal of the lesions with isopropyl alcohol 70%, which was performed on our patient by scrubbing the lesions with soaked gauze (Figure 2). Indeed, removal with isopropyl alcohol 70% is both the therapeutic and diagnostic procedure for TFFD.^1-8 Of note, dermatitis neglecta is histologically and clinically identical to TFFD, albeit with a history of uncleanly habits or exposure to dirty environments.

The diagnosis of TFFD often is discovered incidentally as physicians wipe the area with alcohol to prepare for biopsy.¹ Occasionally, vigorous scrubbing is needed to completely remove the lesions, and without this effort the lesions may be easily mistaken for another cutaneous process.³ Failure to consider TFFD as a diagnosis has led to unnecessary endocrine workups and invasive biopsies.⁴ Therefore, physicians should have early clinical suspicion of TFFD and be aware of the bedside diagnostic procedure using isopropyl alcohol.

Older patients with refractory angioimmunoblastic T cell lymphoma (AITL) appear to respond well to treatment with 5-azacytidine, regardless of mutations.

Francois Lemonnier, MD, of Henri Mondor University Hospitals in Créteil, France, and his colleagues, reported on a retrospective series of 12 AITL patients who received 5-azacytidine for concomitant myeloid neoplasm or as compassionate therapy for relapsed or refractory AITL. The findings were published in Blood.

Patients were given 5-azacytidine subcutaneously at a dose of 75 mg/m² daily for 7 consecutive days. The treatment was given every 28 days until progression or unacceptable toxicity for a median of 5.5 cycles. Along with 5-azacytidine, half of the patients received rituximab due to the presence of EBV replication or EBV B-blasts in the lymph node biopsy.

The patients were assessed via CT scan and responses were evaluated by investigators following the Cheson criteria.

This was a heavily pretreated patient population. The median age was 70 years and 11 of the patients had relapsed or refractory disease and had received a median of two lines of therapy. There was only one treatment-naive patient in the series.

Treatment with 5-azacytidine produced an overall response rate of 75%, with six patients achieving a complete response and three patients achieving a partial response. The median progression-free survival was 15 months and median overall survival was 21 months at a median follow-up of 27 months.

The researchers noted that some elderly patients with poor performance status achieved a sustained response after treatment with an acceptable tolerance.

Treatment was well tolerated overall. There were no treatment-related deaths and no patients developed neutropenia. Three patients required transfusion and another had grade 3 diarrhea.

The researchers also performed molecular studies using targeted deep sequencing. They detected TET2 mutations in all 12 patients, with seven patients having two mutations. Four patients had DNMT3A mutations, five patients had RHOA mutations, and four patients had p.G17V substitution. One patient had an IDH2^R172 mutation.

Since all patients had a TET2 mutation, the researchers were unable to assess its impact on treatment response. However, they saw no association between the number of TET2 mutations and treatment response, or mutations in DNMT3A, IDH2, and RHOA and treatment response.

The study was funded by a grant from the Leukemia & Lymphoma Society. Three of the coauthors received honoraria from Celgene.

Fibromyalgia patients with no documented suicide attempt spent far more hours in face-to-face meetings with providers than did those who made a suicide attempt over a 20-year period at a single academic medical center. The results, based on a machine-learning analysis of electronic health records, shed more light on the heavy burden of suicidality among patients with rheumatologic illnesses.

“People who didn’t have suicide attempts were present at the doctor 50 hours in a year, compared to less than an hour in a year for those who did attempt suicide. It’s a staggering difference,” said study author Lindsey McKernan, PhD, of the department of psychiatry and behavioral sciences at Vanderbilt University, Nashville, Tenn. What’s more, patients who did not have suicidal thoughts averaged about 6 office hours per year, compared with less than 2 hours for those with suicidal ideation (Arthritis Care Res. 2018 Sep 7. doi: 10.1002/acr.23748).

Fibromyalgia patients are at about ten times the risk of suicide as the general population, and rates of depression and anxiety are higher in patients with rheumatoid arthritis, ankylosing spondylitis, and psoriatic disease as well.

Still, mental health issues often go unaddressed. “Many times rheumatologists focus on the patient’s joints and their rheumatologic illness, and they don’t focus on their mental health, and as a result depression in a suicidal patient is, I think, more often missed in a rheumatologic practice than it should be,” said Rakesh Jain, MD, of the department of psychiatry at Texas Tech University, Odessa.

But that gap isn’t for lack of awareness, says Barton Wise, MD, of the departments of orthopedic surgery and internal medicine at the University of California, Davis. “In general, people recognize that depression is a major problem in their patients,” he said. He was the lead author of a study that found that rheumatologists often lack the time, confidence, and connections to properly address a patient’s mental health needs (J Clin Rheumatol. 2016 Sep;22[6]:307-11).

Together, the two studies underscore the pressing need for better mental health care among rheumatology patients. Such issues often take a back seat to a rheumatologist’s primary concern about joint and overall health, but studies have shown that mental health issues are tied to worse rheumatologic disease outcomes. “Addressing comorbid depression will just make the rheumatological outcome be better. So why not do it?” Dr. Jain said.

Screening is a key consideration, according to Dr. Jain, who recommends the Patient Health Questionnaire-9. But even when a problem arises, rheumatologists may lack the confidence to tackle mental health issues. This can be addressed through various resources, such as courses at professional meetings, but another challenge awaits. Rheumatologists may also be unsure of who should be responsible for handling mental health concerns. Even though the rheumatologist may see the patient more often than his or her other providers, “you often feel that you can’t manage everything,” Dr. Wise said.

One way to address that is to establish relationships with mental health providers who can receive referrals for patients who require it. In academic medical centers or other large institutions, relationships can be formalized, so that a patient could see a psychiatrist on the same day as the rheumatologist visit. He even suggests group sessions for patients with similar comorbidities, such as depression related to fibromyalgia or lupus.
 

Special challenges

Rheumatologic conditions are well documented to have heightened rates of suicide and mental health issues, and this may be related to some of the additional challenges such patients face. Many have chronic pain, which in itself is a risk factor for suicide.

Fibromyalgia can be particularly difficult because patients struggle to communicate about their condition with their clinician and even with loved ones. “Patients report feeling stigmatized and often struggle to communicate about what’s happening in their bodies. The pain can change location and intensity, and it doesn’t show up on medical tests,” Dr. McKernan said.

Another burden is that rheumatologic patients typically have high levels of inflammation, a characteristic that has been linked to lower responses to some antidepressants, according to Dr. Jain.

Antidepressants should still be considered for these patients, but they should be combined with other treatments or management techniques, he says. He emphasizes the importance of a low-inflammatory diet, exercise, and other lifestyle factors. He has also created the free Wild 5 Wellness program, which seeks to broadly improve wellness in patients with chronic pain and mental health challenges.

Physician response

The results of the study on fibromyalgia patients suggests another avenue toward improving mental health. The researchers examined data on 8,879 patients with fibromyalgia, using data collected between 1998 and 2017. There were 34 suicide attempts and 96 cases of suicidal ideation. A machine-learning algorithm spat out some factors associated with heightened suicide risk, such as fatigue, dizziness, and weakness, as well as obesity and drug dependence.

But it also generated some associations that weren’t obviously related, such as receiving a flu shot or taking vitamin supplements. “There were a lot of things associated with routine medical care in the patients who didn’t have thoughts about suicide and didn’t attempt suicide. So we looked at how much time people spent with their doctor. I think we might have found an important signal that requires further investigation in bigger samples, and also in other populations. If we can look at people who are at risk [of suicide] but who aren’t engaged with their doctors, that gives us a potential avenue to do something about it, where we can get them connected with a provider, or reconnected if they’ve fallen off, or give them a call to see how they’re doing,” Dr. McKernan said.

In fact, the research suggests that such an effort alone might be enough to reduce suicidality, since patient-provider contact appears to be so important.

“I know in the past that physicians have expressed feeling frustrated – like they don’t have some sort of [mental health] intervention to provide patients who have fibromyalgia. This might show that continuing to see the patient, to stay engaged, may have intrinsic benefit that serves almost like an intervention in itself,” Dr. McKernan said.

Dr. McKernan, Dr. Jain, and Dr. Wise had no financial conflicts of interest.

Fibromyalgia can be particularly difficult because patients struggle to communicate about their condition with their clinician and even with loved ones. “Patients report feeling stigmatized and often struggle to communicate about what’s happening in their bodies. The pain can change location and intensity, and it doesn’t show up on medical tests,” Dr. McKernan said.

Another burden is that rheumatologic patients typically have high levels of inflammation, a characteristic that has been linked to lower responses to some antidepressants, according to Dr. Jain.

Antidepressants should still be considered for these patients, but they should be combined with other treatments or management techniques, he says. He emphasizes the importance of a low-inflammatory diet, exercise, and other lifestyle factors. He has also created the free Wild 5 Wellness program, which seeks to broadly improve wellness in patients with chronic pain and mental health challenges.

Physician response

The results of the study on fibromyalgia patients suggests another avenue toward improving mental health. The researchers examined data on 8,879 patients with fibromyalgia, using data collected between 1998 and 2017. There were 34 suicide attempts and 96 cases of suicidal ideation. A machine-learning algorithm spat out some factors associated with heightened suicide risk, such as fatigue, dizziness, and weakness, as well as obesity and drug dependence.

But it also generated some associations that weren’t obviously related, such as receiving a flu shot or taking vitamin supplements. “There were a lot of things associated with routine medical care in the patients who didn’t have thoughts about suicide and didn’t attempt suicide. So we looked at how much time people spent with their doctor. I think we might have found an important signal that requires further investigation in bigger samples, and also in other populations. If we can look at people who are at risk [of suicide] but who aren’t engaged with their doctors, that gives us a potential avenue to do something about it, where we can get them connected with a provider, or reconnected if they’ve fallen off, or give them a call to see how they’re doing,” Dr. McKernan said.

In fact, the research suggests that such an effort alone might be enough to reduce suicidality, since patient-provider contact appears to be so important.

“I know in the past that physicians have expressed feeling frustrated – like they don’t have some sort of [mental health] intervention to provide patients who have fibromyalgia. This might show that continuing to see the patient, to stay engaged, may have intrinsic benefit that serves almost like an intervention in itself,” Dr. McKernan said.

Dr. McKernan, Dr. Jain, and Dr. Wise had no financial conflicts of interest.

Clinical question: Can a procalcitonin (PCT)–guided strategy safely reduce antibiotic exposure in patients admitted to the ICU with severe acute exacerbations of chronic obstructive pulmonary disease (COPD) with or without pneumonia?

Background: Studies have demonstrated PCT-based strategies can safely reduce antibiotic use in patients without severe lower respiratory tract infections, community-acquired pneumonia, or acute exacerbations of COPD. The data on safety of PCT-based strategies in critically ill patients is limited.

Study design: Prospective, multicenter, randomized, controlled trial.

Setting: ICUs of 11 hospitals in France, including 7 tertiary care hospitals.

Synopsis: In this study 302 patients admitted to the ICU with severe exacerbations of COPD with or without pneumonia were randomly assigned to groups with antibiotic therapy guided by a PCT protocol or standard guidelines. Overall, the study failed to demonstrate noninferiority of a PCT-based strategy to reduce exposure to antibiotics. Specifically, the adjusted difference in mortality was 6.6% higher (90% confidence interval, 0.3%-13.5%) in the intervention group with no significant reduction in antibiotic exposure.

One limitation of this study was that it was an open trial in which clinicians were aware that their management was being observed.

Bottom line: A PCT-based algorithm was not effective in safely reducing antibiotic exposure in patients with acute exacerbations of COPD admitted to the ICU.

Aberrations in oncogenic pathways and immune modulation influence treatment response in patients with metastatic leiomyosarcoma or liposarcoma, based on an analysis of whole-exome sequencing of tumor samples from patients in a completed phase 3 randomized trial comparing trabectedin and dacarbazine.

In that trial, trabectedin benefit was mostly seen in patients with leiomyosarcoma, as well as in patients with myxoid/round cell sarcomas, and less so in those with dedifferentiated and pleomorphic liposarcomas.

Gurpreet Kapoor, PhD, of LabConnect, Seattle, and colleagues examined aberrations in oncogenic pathways (DNA damage response, PI3K, MDM2-p53) and in immune modulation and then correlated the genomic aberrations with prospective data on clinical outcomes in the trial.

For the study, presented at the annual meeting of the American Society of Clinical Oncology in Chicago, archival tumor samples were collected from 456 of the 518 patients; 180 had uterine leiomyosarcomas, 149 had nonuterine leiomyosarcomas, 66 had dedifferentiated liposarcomas, 46 had myxoid liposarcomas, and 15 had pleomorphic liposarcomas.

Peripheral blood samples from a subset of 346 patients were also analyzed as matched normal to filter noise from nonpathogenic variants in the whole-exome sequencing.

Consistent with sarcoma data from The Cancer Genome Atlas, frequent homozygous gene deletions with relatively low mutational load were noted in these leiomyosarcoma and liposarcoma samples. TP53 and RB1 alterations were more frequent in leiomyosarcomas than in liposarcomas and were not associated with clinical outcomes. Analyses of 103 DNA damage-response genes found somatic alterations exceeded 20% across subtypes and correlated with improved progression-free survival in only uterine leiomyosarcomas (hazard ratio, 0.63; P = .03).

Genomic alterations in PI3K pathway genes were noted in 30% of myxoid liposarcomas and were associated with a worse rate of progression-free survival (HR, 3.0; P = .045).

A trend towards better overall survival was noted in dedifferentiated liposarcoma patients with MDM2 amplification as compared with normal MDM2 copy number.

Certain subtype-specific genomic aberrations in immune modulation pathways were associated with worse clinical outcomes in patients with uterine leiomyosarcoma or dedifferentiated liposarcoma. Alterations in immune suppressors were associated with improved clinical outcomes in nonuterine leiomyosarcomas and alterations in lipid metabolism were associated with improved clinical outcomes in dedifferentiated liposarcomas.

The invited discussant for the study, Mark Andrew Dickson, MD, of Memorial Sloan Kettering Cancer Center, New York, noted that “the real take-home here is that the TMBs (tumor mutation burdens) are relatively low across all of the L-type sarcomas.

“The pattern and prevalence of genomic aberrations that we’re seeing in this cohort of patients prospectively analyzed on a clinical trial are consistent with prior reports. ... including CDK4 and MDM2 in dedifferentiated liposarcoma, PI3-kinase in some myxoid/round cells, p53 in leiomyosarcoma and liposarcoma, and so on.”

Generally, tumor mutation burden is low in L-type sarcomas, and there are some intriguing associations with benefit to therapies, such as PI3-kinase pathway and potential resistance to trabectedin and high tumor mutation burden and potential sensitivity to trabectedin, that need to be explored and validated in another larger cohort, he said.

“I also am increasingly coming to terms with the fact that the tumors like leiomyosarcoma, which have low tumor mutation burden, and which so far have proven fairly immune to immunotherapy, based on all of the negative PD-1 data that we’ve seen, and that also have recurrent, relatively unactionable mutations, like p53 and Rb, remain very difficult to treat,” Dr. Dickson concluded.

Final analysis of the phase 3 DUO trial has shown monotherapy with oral duvelisib results in a statistically significant improvement in progression-free survival (PFS) and overall response rate (ORR) compared to monotherapy with ofatumumab for patients with relapsed or refractory chronic lymphocytic leukemia/small lympchocytic lymphoma (CLL/SLL).

PFS for all patients as assessed by Independent Review Committee (IRC) was a median 13.3 months with duvelisib compared to 9.9 months with ofatumumab (P<0.0001).

ORR was significantly higher with duvelisib, 74% compared to 45%, P<0.0001, regardless of deletion 17p status.

Duvelisib (Copiktra™) was recently approved by the U.S. Food and Drug Administration for CLL/SLL based in part on this head-to-head trial.

The investigators reported the results in Blood.

"The way we treat patients with CLL is changing rapidly as we move from standard chemotherapy-based approaches to more targeted therapies," said principal investigator Ian W. Flinn, MD, PhD, of Sarah Cannon Research Institute in Nashville.

"Based on these data, duvelisib may offer a new treatment option for patients who otherwise may have limited options."

Duvelisib is an oral, dual inhibitor of phosphoinositide 3-kinase (PI3K)-δ and -γ, which means it blocks the survival and proliferation of malignant B cells and also disrupts the recruitment and differentiation of T cells and macrophages within the tumor microenvironment.

Ofatumumab is a humanized anti-CD20 antibody with single-agent efficacy in refractory CLL. It is approved by the FDA as a treatment option in CLL.

Study design

Investigators randomized 319 relapsed or refractory CLL/SLL patients, 160 to the duvelisib arm and 159 to the ofatumumab arm.

Patients in the duvelisib arm self-administered 25 mg capsules twice daily continuously in 28-day cycles. They could take duvelisib for up to 18 cycles, until disease progression or unacceptable toxicity.

Ofatumumab-treated patients received infusions as approved in the product labeling for monotherapy in relapsed CLL. Dosing of ofatumumab could not exceed 12 doses in 7 cycles.

Prophylaxis for Pneumocystis jirovecci was required for all patients on both treatment arms.

Patients were allowed to crossover to a separate extension study to receive the opposite therapy if they had progressive disease.

They were followed for a median of 22.4 months.

Patient characteristics

According to the investigators, patient characteristics were well balanced between the arms.

The majority (60%) were male and the median age in both arms was 69. Most had an ECOG performance status of 0 or 1; 7% in the duvelisib arm and 10% in the ofatumumab arm had a performance status of 2.

Other patient characteristics in the duvelisib and ofatumumab arms, respectively, were:

• Time from initial diagnosis: 7.5 years, 6.7 years
• CLL/SLL, %: 97/5, 99/2
• Bulky disease: 46%, 45%
• Baseline lymphocyte counts: 38x109/L, 35x109/L
• Deletion 17p and/or TP53 mutation: 31%, 33%
• Median number of prior therapies: 2 in each arm
• Previous alkylating agent: 93%, 95%
• Previous monoclonal antibody: 78%, 83%
• Prior purine analog: 60%, 71%

Of the total patients enrolled, 158 patients in the duvelisib arm and 155 in the ofatumumab arm received treatment, for a median exposure of 50 weeks and 23 weeks, respectively.

Efficacy

In addition to the significantly improved overall PFS and ORR with duvelisib, further analysis revealed that PFS also improved for all predefined subgroups.

High-risk patients with deletion 17p/TP53 mutations also experienced a significant improvement in PFS with duvelisib of 12.7 months compared to 9.0 months with ofatumumab by IRC (P=0.0002).

The estimated probability of being progression-free for these patients at 6 and 12 moths was 73% and 55% with duvelisib and 63% and 30% with ofatumumab.

The investigators pointed out that duvelisib treatment was particularly effective in eliciting a lymph node response—85.0% compared to 15.7% with ofatumumab as assessed by IRC (P<0.0001).

Median overall survival was not reached in either arm. The 12-month probability of survival was 86% for both treatments.

Safety

Median treatment exposure was almost twice as long in the duvelisib arm because ofatumumab treatment was not allowed to exceed 12 doses as specified in the prescribing information.

The investigators explained this resulted in a longer adverse event (AE) reporting period for duvelisib.

One hundred twenty-four duvelisib-treated patients discontinued treatment, most commonly due to AEs (35%), disease progression (22%), subject withdrawal (8%), and death (8%).

All ofatumumab-treated patients discontinued treatment by the time of data cutoff, and 67% had completed treatment as per protocol. Others discontinued due to disease progression (20%), subject withdrawal (5%), and AEs (4%).

Eight (5%) duvelisib patients crossed over to ofatumumab therapy at the time of disease progression, and 89 (57%) ofatumumab-treated patients crossed over to duvelisib.

Nearly all patients in both arms experienced an AE.

The most common hematologic malignancies with duvelisib and ofatumumab, respectively, occurring in 10% or more patients were neutropenia (33%, 21%), anemia (23%, 10%), and thrombocytopenia (15%, 6%).

The most common nonhematologic AES with duvelisib were diarrhea (51%), pyrexia (29%), nausea (23%), and cough (21%).

With ofatumumab, the most common nonhematologic AES were infusion-related reaction (19%), cough (14%), and diarrhea, rash, and fatigue (12% each).

Grade 3 or greater AEs occurred in 87% of duvelisib-treated patients and 48% in the ofatumumab arm.

The most common grade 3 or greater events with duvelisib were neutropenia (30%), diarrhea (15%), pneumonia (14%), and anemia (13%).

With ofatumumab, only neutropenia (17%) of grade 3 or higher occurred in 10% or more patients.

Severe immune-related toxicities with duvelisib included colitis (12%) and pneumonitis, alanine transaminase (ALT) or aspartate transaminase (AST) increase (3% each). The events were managed with dose interruptions and steroid therapy for pneumonitis or colitis. All reported events resolved, and none was fatal.

Infectious AEs occurred more frequently with duvelisib, 69% compared to 43% in the ofatumumab arm. Pneumonia (18%) and upper respiratory tract infection (16%) were the most common events.

Three patients in the duvelisib arm and 1 in the ofatumumab arm contracted Pneumocystis jirovecii.

The most frequently reported serious AE was pneumonia (duvelisib 15%; ofatumumab 3%).

Nineteen fatal AEs occurred in patients on the duvelisib arm, 4 of which were related to the study drug: staphylococcal pneumonia (n = 2), sepsis (n=1), and general health deterioration (n = 1).

Seven fatal AEs occurred in patients on the ofatumumab arm, although none was attributed to ofatumumab.

The most common nonhematologic AES with duvelisib were diarrhea (51%), pyrexia (29%), nausea (23%), and cough (21%).

With ofatumumab, the most common nonhematologic AES were infusion-related reaction (19%), cough (14%), and diarrhea, rash, and fatigue (12% each).

Grade 3 or greater AEs occurred in 87% of duvelisib-treated patients and 48% in the ofatumumab arm.

The most common grade 3 or greater events with duvelisib were neutropenia (30%), diarrhea (15%), pneumonia (14%), and anemia (13%).

With ofatumumab, only neutropenia (17%) of grade 3 or higher occurred in 10% or more patients.

Severe immune-related toxicities with duvelisib included colitis (12%) and pneumonitis, alanine transaminase (ALT) or aspartate transaminase (AST) increase (3% each). The events were managed with dose interruptions and steroid therapy for pneumonitis or colitis. All reported events resolved, and none was fatal.

Infectious AEs occurred more frequently with duvelisib, 69% compared to 43% in the ofatumumab arm. Pneumonia (18%) and upper respiratory tract infection (16%) were the most common events.

Three patients in the duvelisib arm and 1 in the ofatumumab arm contracted Pneumocystis jirovecii.

The most frequently reported serious AE was pneumonia (duvelisib 15%; ofatumumab 3%).

Nineteen fatal AEs occurred in patients on the duvelisib arm, 4 of which were related to the study drug: staphylococcal pneumonia (n = 2), sepsis (n=1), and general health deterioration (n = 1).

Seven fatal AEs occurred in patients on the ofatumumab arm, although none was attributed to ofatumumab.

Final analysis of the phase 3 DUO trial has shown monotherapy with oral duvelisib results in a statistically significant improvement in progression-free survival (PFS) and overall response rate (ORR) compared to monotherapy with ofatumumab for patients with relapsed or refractory chronic lymphocytic leukemia/small lympchocytic lymphoma (CLL/SLL).

PFS for all patients as assessed by Independent Review Committee (IRC) was a median 13.3 months with duvelisib compared to 9.9 months with ofatumumab (P<0.0001).

ORR was significantly higher with duvelisib, 74% compared to 45%, P<0.0001, regardless of deletion 17p status.

Duvelisib (Copiktra™) was recently approved by the U.S. Food and Drug Administration for CLL/SLL based in part on this head-to-head trial.

The investigators reported the results in Blood.

"The way we treat patients with CLL is changing rapidly as we move from standard chemotherapy-based approaches to more targeted therapies," said principal investigator Ian W. Flinn, MD, PhD, of Sarah Cannon Research Institute in Nashville.

"Based on these data, duvelisib may offer a new treatment option for patients who otherwise may have limited options."

Duvelisib is an oral, dual inhibitor of phosphoinositide 3-kinase (PI3K)-δ and -γ, which means it blocks the survival and proliferation of malignant B cells and also disrupts the recruitment and differentiation of T cells and macrophages within the tumor microenvironment.

Ofatumumab is a humanized anti-CD20 antibody with single-agent efficacy in refractory CLL. It is approved by the FDA as a treatment option in CLL.

Study design

Investigators randomized 319 relapsed or refractory CLL/SLL patients, 160 to the duvelisib arm and 159 to the ofatumumab arm.

Patients in the duvelisib arm self-administered 25 mg capsules twice daily continuously in 28-day cycles. They could take duvelisib for up to 18 cycles, until disease progression or unacceptable toxicity.

Ofatumumab-treated patients received infusions as approved in the product labeling for monotherapy in relapsed CLL. Dosing of ofatumumab could not exceed 12 doses in 7 cycles.

Prophylaxis for Pneumocystis jirovecci was required for all patients on both treatment arms.

Patients were allowed to crossover to a separate extension study to receive the opposite therapy if they had progressive disease.

They were followed for a median of 22.4 months.

Patient characteristics

According to the investigators, patient characteristics were well balanced between the arms.

The majority (60%) were male and the median age in both arms was 69. Most had an ECOG performance status of 0 or 1; 7% in the duvelisib arm and 10% in the ofatumumab arm had a performance status of 2.

Other patient characteristics in the duvelisib and ofatumumab arms, respectively, were:

• Time from initial diagnosis: 7.5 years, 6.7 years
• CLL/SLL, %: 97/5, 99/2
• Bulky disease: 46%, 45%
• Baseline lymphocyte counts: 38x109/L, 35x109/L
• Deletion 17p and/or TP53 mutation: 31%, 33%
• Median number of prior therapies: 2 in each arm
• Previous alkylating agent: 93%, 95%
• Previous monoclonal antibody: 78%, 83%
• Prior purine analog: 60%, 71%

Of the total patients enrolled, 158 patients in the duvelisib arm and 155 in the ofatumumab arm received treatment, for a median exposure of 50 weeks and 23 weeks, respectively.

Efficacy

In addition to the significantly improved overall PFS and ORR with duvelisib, further analysis revealed that PFS also improved for all predefined subgroups.

High-risk patients with deletion 17p/TP53 mutations also experienced a significant improvement in PFS with duvelisib of 12.7 months compared to 9.0 months with ofatumumab by IRC (P=0.0002).

The estimated probability of being progression-free for these patients at 6 and 12 moths was 73% and 55% with duvelisib and 63% and 30% with ofatumumab.

The investigators pointed out that duvelisib treatment was particularly effective in eliciting a lymph node response—85.0% compared to 15.7% with ofatumumab as assessed by IRC (P<0.0001).

Median overall survival was not reached in either arm. The 12-month probability of survival was 86% for both treatments.

Safety

Median treatment exposure was almost twice as long in the duvelisib arm because ofatumumab treatment was not allowed to exceed 12 doses as specified in the prescribing information.

The investigators explained this resulted in a longer adverse event (AE) reporting period for duvelisib.

One hundred twenty-four duvelisib-treated patients discontinued treatment, most commonly due to AEs (35%), disease progression (22%), subject withdrawal (8%), and death (8%).

All ofatumumab-treated patients discontinued treatment by the time of data cutoff, and 67% had completed treatment as per protocol. Others discontinued due to disease progression (20%), subject withdrawal (5%), and AEs (4%).

Eight (5%) duvelisib patients crossed over to ofatumumab therapy at the time of disease progression, and 89 (57%) ofatumumab-treated patients crossed over to duvelisib.

Nearly all patients in both arms experienced an AE.

The most common hematologic malignancies with duvelisib and ofatumumab, respectively, occurring in 10% or more patients were neutropenia (33%, 21%), anemia (23%, 10%), and thrombocytopenia (15%, 6%).

The most common nonhematologic AES with duvelisib were diarrhea (51%), pyrexia (29%), nausea (23%), and cough (21%).

With ofatumumab, the most common nonhematologic AES were infusion-related reaction (19%), cough (14%), and diarrhea, rash, and fatigue (12% each).

Grade 3 or greater AEs occurred in 87% of duvelisib-treated patients and 48% in the ofatumumab arm.

The most common grade 3 or greater events with duvelisib were neutropenia (30%), diarrhea (15%), pneumonia (14%), and anemia (13%).

With ofatumumab, only neutropenia (17%) of grade 3 or higher occurred in 10% or more patients.

Severe immune-related toxicities with duvelisib included colitis (12%) and pneumonitis, alanine transaminase (ALT) or aspartate transaminase (AST) increase (3% each). The events were managed with dose interruptions and steroid therapy for pneumonitis or colitis. All reported events resolved, and none was fatal.

The U.S. Food and Drug Administration (FDA) approved emicizumab-kxwh (Hemlibra) for prophylaxis to prevent or reduce the frequency of bleeding episodes in adult and pediatric patients, including newborns, with hemophilia A with or without factor VIII (FVIII) inhibitors.

Emicizumab is a humanized bispecific factor IXa- and factor X-directed antibody for patients with congenital FVIII deficiency.

It was first approved in 2017 for hemophilia A patients with FVIII inhibitors.

The current approval expands the indication to include patients without FVIII inhibitors and provides new dosing regimens.

The FDA based the current approval on the HAVEN 3 and HAVEN 4 trials.

HAVEN 3 (NCT02847637)

This multicenter trial randomized 89 patients with severe hemophilia A without FVIII inhibitors to receive emicizumab prophylaxis at one of 3 dose levels: 1.5 mg/kg once weekly (ARM A), 3 mg/kg once every two weeks (Arm B), or no prophylaxis (Arm C). Patients had previously received on-demand treatment with FVIII.

Before the start of the trial, investigators stratified patients by 24-week bleed rate—fewer than 9 bleeds and 9 or more bleeds.

Patients were treated with emicizumab for a minimum of 24 weeks.

Patients in Arm A experienced a 96% reduction in annualized bleed rate (ABR) compared to patients with no prophylaxis (ABR ratio=0.04; P<0.0001).

Patients in Arm B had a 97% reduction in ABR compared to patients with no prophylaxis (ABR ratio=0.03; P<0.0001).

The trial met all bleed-related secondary endpoints, such as all bleeds, treated spontaneous bleeds, treated joint bleeds, and treated target joint bleeds.

HAVEN 4 (NCT03020160)

This was a single-arm multicenter trial in 48 adult and adolescent males with hemophilia A with or without FVIII inhibitors. The patients had previously received on-demand or prophylactic treatment with FVIII or bypassing agents.

The study was conducted in two parts: a run-in of 7 patients to determine the pharmacokinetics after a single 6 mg/kg dose in four weeks. This was followed by the same dose once every four weeks for at least 24 weeks.

The second part was an expansion cohort of 41 patients who received emicizumab at 3 mg/kg once weekly for the first four weeks followed by 6 mg/kg once every four weeks for at least 24 weeks.

The ABR for treated bleeds was 2.4 (95% CI: 1.38, 4.28) and the median ABR was 0.0 (interquartile range: 0.00, 2.08).

The recommended loading dose is 3 mg/kg once weekly for the first four weeks for all prophylactic regimens.

Safety

The prescribing information for emicizumab includes a warning about thrombotic microangiopathy and thromboembolism.

These events were reported on average when a cumulative amount of >100 U/kg/24 hours of activated prothrombin complex concentrate (aPCC) was administered for 24 hours or more to patients receiving emicizumab prophylaxis.

According to the warning box, patients should be monitored for these events if aPCC is administered. If symptoms occur, aPCC should be discontinued and emicizumab dosing suspended.

The most common adverse reactions reported for emicizumab with an incidence ≥10% were injection site reactions (22%), headache (15%), and arthralgia (15%).

Emicizumab is manufactured by Genentech, Inc., a member of the Roche Group.

Additional data on emicizumab can be found in an earlier Roche media release.

There is little justification for the use of vitamin D supplementation for the prevention of fractures or falls or for increasing bone density, according to the authors of a meta-analysis that found no benefits from supplementation.

copyright istock/Thinkstock

A systematic review and meta-analysis, published in the Oct. 4 edition of Lancet Diabetes & Endocrinology, examined 81 randomized controlled trials – involving 53,537 participants – of the effects of vitamin D supplementation on fractures, falls, or bone mineral density.

In the pooled analyses, researchers found that vitamin D supplementation did not reduce total fracture, hip fracture, or falls, even in trials in which participants took doses greater than 800 IU/day. Their results were similar when researchers compared high doses and low doses in their trials.

Similarly, vitamin D supplementation was not associated with any clinically relevant improvements in bone mineral density at any site; lumbar spine, total hip, femoral neck, forearm, or total body.

Even a post hoc analysis of randomized, controlled trials that compared daily high doses with daily low doses, as well as trials that compared intermittent high doses with intermittent low doses found no significant interactions for any outcome.

The paper also explored whether baseline vitamin D levels might influence outcomes. Eighteen trials in the analysis reported the results of subgroup analyses using baseline serum 25-hydroxyvitamin D (25[OH]D); three found no effects of vitamin D supplements in different subgroups of baseline, five studies found no effects of subgroups or interaction with baseline serum 25[OH]D, and one found mixed effects with respect to falls.

The outcomes for bone mineral density, as related to baseline serum 25[OH]D, were slightly more mixed. One trial found a positive effect of vitamin D supplements a bone mineral density for different subgroups of baseline serum, five trials reported mixed effects, and eight trials found no effects.

“The strengths of the current analyses are that they are comprehensive, include all available data from a large number of new trials, and concomitantly assess the major clinical and surrogate endpoints for musculoskeletal health,” wrote Mark J. Bolland, MD, of the department of medicine at the University of Auckland (New Zealand), and his coauthors. “Therefore, there is little justification for the use of vitamin D supplements to maintain or improve musculoskeletal health, and clinical guidelines should reflect these findings.”

They also conducted trial sequential analyses, which is a type of cumulative meta-analysis. For each outcome, they set a relative risk reduction threshold, then progressively reduced that threshold until the optimum sample size for that threshold exceeded the actual sample size.

“The trial sequential analyses are important because they provide estimates about the reliability of current evidence and the likelihood of future trials to change current conclusions,” the authors wrote.

Using this approach, they once again found clear evidence that vitamin D supplementation did not reduce fractures or falls for any measure of relative risk reduction. For hip fracture, the trial sequential analysis even found some uncertainty as to whether vitamin D supplementation might increase the risk of hip fractures.

Given the results of the trial sequential analyses, the authors argued that further similar trials were unlikely to alter their conclusion.

“If a large future trial has markedly different results to the current trials, adding its results will substantially increase the heterogeneity of the trial results, which in turn will reduce the weighting the new large trial receives in the pooled analyses,” they wrote. “Thus, adding a positive result from a large randomized, controlled trial will have only a small effect on the pooled result and is unlikely to alter the conclusions of these meta-analyses.”

They also noted that some of the studies had methodological limitations, and smaller studies of shorter duration tended to have “inflated” effect sizes, such that “the results of small, short-duration studies should be interpreted very cautiously, since they might not be replicated in larger, longer studies.”

The study was funded by the Health Research Council of New Zealand. Two authors declared grants from the Health Research Council during the study, one author is a shareholder in a company that provides bone mineral density measurements, and one reported grants from the Scottish Government Health and Social Care Directorates during the study.
