Triple therapy ups response in refractory mantle cell lymphoma
A combination of ibrutinib, lenalidomide, and rituximab produced an overall response rate of 76% at 17.8 months median follow-up among 50 adults with relapsed or refractory mantle cell lymphoma, according to an open-label, single-arm, phase 2 trial.
There were complete responses in 28 patients (56%) and partial responses in 10 (20%). Median progression-free survival was 16 months and median overall survival was 22 months. Similar proportions of patients, with and without TP53 mutations, had overall and complete responses, suggesting that triple therapy might be particularly useful in patients with high-risk genetic features.
“Our results provide preliminary evidence that the triplet combination of ibrutinib, lenalidomide, and rituximab is an active regimen in patients with relapsed or refractory mantle cell lymphoma, and should be evaluated in a prospective randomized controlled trial,” wrote Mats Jerkeman, MD, of Lund University, Sweden, and colleagues. The report was published in The Lancet Haematology.
“Addition of lenalidomide to ibrutinib and rituximab might increase the proportion of patients who have complete remission ... Previous studies reported complete responses in 44% of patients on ibrutinib and rituximab, in 36% of patients on rituximab and lenalidomide, and in 19% of patients on ibrutinib alone,” they wrote.
Treatment was divided into an induction phase of 12 cycles of 28 days with all three drugs and a maintenance phase with ibrutinib and rituximab only, given until disease progression or unacceptable toxicity. All the patients had previously been treated with at least one rituximab-containing regimen.
Janssen and Celgene funded the work. Dr. Jerkeman reported ties to Janssen and Celgene, as well as AbbVie and Gilead.

Rituximab Still Proves Safe Long Term
Rituximab, a B-cell–depleting agent, has been found safe and effective in clinical trials of patients with multiple sclerosis and patients with rheumatoid arthritis, among others. However, progressive multifocal leukoencephalopathy (PML) and malignancies have been reported in patients with lymphoma, rheumatoid arthritis, and lupus who also received multiple immunosuppressive therapies, say researchers from Wayne State University in Michigan and University of Chicago in Illinois. In studies with ocrelizumab, which also depletes B-cells, adverse effects (AEs) have included infections, such as, herpes virus-associated infection, and neoplasms.
Although most research has found rituximab and ocrelizumab safe and effective, there is a “paucity of literature” on the safety of continuous B-cell depletion over a long period, the researchers say. They conducted a retrospective study involving 29 patients with immune-mediated neurologic disorders who received continuous cycles of rituximab infusions every 6 to 9 months for up to 7 years. Although small, the study was longer than the trials with ocrelizumab in multiple sclerosis . The mean duration of treatment was 51 months; with a mean of 9 treatment cycles.
The researchers found a low incidence of adverse events and prolonged rituximab-induced B-cell depletion did not lead to any life-threatening AEs, including malignancy. Overall, 32 AEs were reported. Four were serious; 3 were noted after 9 cycles (48 months), and 1 after 11 cycles (60 months). There were no cases of PML or malignancies. Repeated rituximab infusions were well tolerated The rate of AEs remained low over the 7-year observation period.

CLL drug in limited supply outside U.S.
Ofatumumab (Arzerra), a monoclonal antibody treatment for chronic lymphocytic leukemia, will soon be available outside the United States through compassionate use programs only. The drug will continue to be widely available in the United States.
Novartis announced in January that it would begin limiting the availability of the drug outside of the United States and would work with regulatory authorities to set up compassionate use programs for patients who are currently being treated with the drug. Patients who use these programs will receive the drug for free.
The decision was driven by the surge in CLL drugs that have become available over the last 5 years, according to Novartis.
The decision to pull the drug from international markets will not affect its use in ongoing clinical trials, particularly two phase 3 studies in relapsing multiple sclerosis and indolent non-Hodgkin lymphoma.

Continue to opt for HDT/ASCT for multiple myeloma
High-dose therapy with melphalan followed by autologous stem cell transplant (HDT/ASCT) is still the best option for multiple myeloma even after almost 2 decades with newer and highly effective induction agents, according to a recent systematic review and two meta-analyses.
Given the “unprecedented efficacy” of “modern induction therapy with immunomodulatory drugs and proteasome inhibitors (also called ‘novel agents’),” investigators “have sought to reevaluate the role of HDT/ASCT,” wrote Binod Dhakal, MD, of the Medical College of Wisconsin, and his colleagues. The report is in JAMA Oncology.
To solve the issue, they analyzed five randomized controlled trials conducted since 2000 and concluded that HDT/ASCT is still the preferred treatment approach.
Despite a lack of demonstrable overall survival benefit, there is a significant progression-free survival (PFS) benefit, low treatment-related mortality, and potential high minimal residual disease-negative rates conferred by HDT/ASCT in newly-diagnosed multiple myeloma, the researchers noted.
The combined odds for complete response were 1.27 (95% confidence interval, 0.97-1.65, P = .07) with HDT/ASCT, compared with standard-dose therapy (SDT). The combined hazard ratio (HR) for PFS was 0.55 (95% CI, 0.41-0.7, P less than .001) and 0.76 for overall survival (95% CI, 0.42-1.36, P = .20) in favor of HDT.
PFS was best with tandem HDT/ASCT (HR, 0.49, 95% CI, 0.37-0.65) followed by single HDT/ASCT with bortezomib, lenalidomide, and dexamethasone consolidation (HR, 0.53, 95% CI, 0.37-0.76) and single HDT/ASCT alone (HR, 0.68, 95% CI, 0.53-0.87), compared with SDT. However, none of the HDT/ASCT approaches had a significant impact on overall survival.
Meanwhile, treatment-related mortality with HDT/ASCT was minimal, at less than 1%.
“The achievement of high [minimal residual disease] rates with HDT/ASCT may render this approach the ideal platform for testing novel approaches (e.g., immunotherapy) aiming at disease eradication and cures,” the researchers wrote.
The researchers reported relationships with a number of companies, including Takeda, Celgene, and Amgen, that make novel induction agents.

Higher Risk of Secondary Cancers for Patients With Mycosis Fungoides
Adult patients with mycosis fungoides (MF) have a higher risk of secondary malignancies, according to a 20-year population-based cohort study. The researchers, from Bezmialem Vakif University in Istanbul, Turkey, say their findings support earlier research about a higher risk of, for instance, Hodgkin lymphoma, chronic leukemia, and lung cancer.
Between 1998 and 2015, the researchers documented 143 cases of cutaneous T-cell lymphoma (CTCL). The majority of patients had early-stage disease.
The researchers also documented 13 cases (9%) of secondary malignancy diagnosed at least 3 months after the diagnosis of CTCL. The cancers included bladder cancer, nasopharynx cancer, renal cell carcinoma, lung cancer, and superficial spreading malignant melanoma.
Older age, stage IV disease, lymphomatoid papulosis, and having CTCL for > 10 years raised the chances of developing secondary solid tumors. In 60% of patients, the secondary malignancies occurred during the first year of diagnosis.
Research has suggested that antilymphoma drugs, particularly alkylating agents, may lead to leukemia, the researchers note. In this study, 6 patients with secondary cancers were getting systemic treatment with interferon or acitretin; 7 were getting no systemic treatment.
The researchers add that MF and hematologic malignancies may share genetic origin, carcinogens, or viruses that affect lymphocyte precursors. They also note that the first neoplasm may produce cytokines that induce development of the secondary neoplasm. The researchers cite research that found MF is a T helper cell 2–mediated disease associated with human leukocyte antigen 2 alleles. Viruses such as Epstein-Barr and herpes simplex also have been implicated.
“Extensive evaluation” for secondary malignancies in adult patients with MF is wise, the researchers advise, particularly if the patient has lymphomatoid papulosis.

Late-breaking abstracts highlight treatment advances in CLL, myeloma, and more
.
In a preplanned interim analysis of data from 389 patients in the randomized phase III Murano trial, venetoclax and rituximab therapy proved “superior to the standard of care and well tolerated, and a major advance in the management of [relapsed/refractory] CLL,” ASH President Kenneth C. Anderson, MD said during a premeeting preview session for the media.
In Murano, venetoclax plus rituximab bettered bendamustine plus rituximab in progression-free survival, overall survival, overall and complete response rates, and number of patients achieving minimal residual disease (MRD) negativity, said Dr. Anderson, who is also director of the Lebow Institute for Myeloma Therapeutics and Jerome Lipper Myeloma Center at Dana-Farber Cancer Institute, Boston.
The results were consistent in all risk subsets, including patients who had high-risk disease by virtue of chromosome 17p deletion, according Dr. Anderson.
In another late-breaking randomized phase III study, known as ALCYONE, adding the CD38-targeting monoclonal antibody daratumumab to standard therapy with bortezomib, melphalan, and prednisone (VMP) resulted in a “doubling” of progression-free survival in patients who had newly diagnosed multiple myeloma and were ineligible for transplantation, he reported.
In the trial of more than 700 patients, daratumumab plus VMP as initial treatment for nontransplant patients was well tolerated and improved outcomes, including overall response rate and the percent of patients who achieved MRD negative status.
“As we saw in CLL, so it’s true in this abstract in myeloma: this is a very major advance,” Dr. Anderson said.
Also during the preview session, ASH Secretary Robert A. Brodsky, MD, discussed the randomized, phase III HERCULES study results, which showed that patients with acquired thrombotic thrombocytopenic purpura (TTP) may benefit when caplacizumab is added to standard therapy. Caplacizumab targets the A1 domain of von Willebrand factor, which inhibits interaction between ultra-large von Willebrand factor and platelets.
In the trial, 145 patients were randomized to receive either plasma exchange alone or plasma exchange and caplacizumab.
Preliminary results suggest “this was a very positive trial” with a primary endpoint of time to platelet response that “greatly favored the caplacizumab arm,” said Dr. Brodsky, professor of medicine and oncology and director of the division of hematology at Johns Hopkins University, Baltimore. “Even the secondary composite endpoint of death, recurrence, and/or major thromboembolic events was much improved with caplacizumab, so this is a very positive trial and potentially a game-changing drug for the management of TTP, which can be very challenging.”
Dr. Brodsky also discussed the Hokusai VTE-Cancer Study, a randomized, open-label, blinded outcome assessment trial that showed the oral factor Xa inhibitor edoxaban was noninferior to subcutaneous dalteparin for the prevention of cancer-associated venous thromboembolism.
With more than 1,000 patients enrolled in 114 centers, the Hokusai VTE-Cancer Study had a primary outcome of the composite of the first recurrent VTE or major bleeding event during follow-up. The primary outcome occurred in 12.8% of patients in the edoxaban group, compared with 13.5% of patients in the dalteparin group (P = .0056 for noninferiority), according to the preliminary published results.
The key question addressed by the trial is whether a newer oral anticoagulant, edoxaban, can substitute for the older, subcutaneously administered low-molecular-weight heparin, dalteparin. The results “confirmed that a newer oral anticoagulant is at least as good and as safe as the low molecular weight heparin,” allowing patients the convenience of an oral therapy, Dr. Brodsky noted.

In a preplanned interim analysis of data from 389 patients in the randomized phase III Murano trial, venetoclax and rituximab therapy proved “superior to the standard of care and well tolerated, and a major advance in the management of [relapsed/refractory] CLL,” ASH President Kenneth C. Anderson, MD said during a premeeting preview session for the media.
In Murano, venetoclax plus rituximab bettered bendamustine plus rituximab in progression-free survival, overall survival, overall and complete response rates, and number of patients achieving minimal residual disease (MRD) negativity, said Dr. Anderson, who is also director of the Lebow Institute for Myeloma Therapeutics and Jerome Lipper Myeloma Center at Dana-Farber Cancer Institute, Boston.
The results were consistent in all risk subsets, including patients who had high-risk disease by virtue of chromosome 17p deletion, according Dr. Anderson.
In another late-breaking randomized phase III study, known as ALCYONE, adding the CD38-targeting monoclonal antibody daratumumab to standard therapy with bortezomib, melphalan, and prednisone (VMP) resulted in a “doubling” of progression-free survival in patients who had newly diagnosed multiple myeloma and were ineligible for transplantation, he reported.
In the trial of more than 700 patients, daratumumab plus VMP as initial treatment for nontransplant patients was well tolerated and improved outcomes, including overall response rate and the percent of patients who achieved MRD negative status.
“As we saw in CLL, so it’s true in this abstract in myeloma: this is a very major advance,” Dr. Anderson said.
Also during the preview session, ASH Secretary Robert A. Brodsky, MD, discussed the randomized, phase III HERCULES study results, which showed that patients with acquired thrombotic thrombocytopenic purpura (TTP) may benefit when caplacizumab is added to standard therapy. Caplacizumab targets the A1 domain of von Willebrand factor, which inhibits interaction between ultra-large von Willebrand factor and platelets.
In the trial, 145 patients were randomized to receive either plasma exchange alone or plasma exchange and caplacizumab.
Preliminary results suggest “this was a very positive trial” with a primary endpoint of time to platelet response that “greatly favored the caplacizumab arm,” said Dr. Brodsky, professor of medicine and oncology and director of the division of hematology at Johns Hopkins University, Baltimore. “Even the secondary composite endpoint of death, recurrence, and/or major thromboembolic events was much improved with caplacizumab, so this is a very positive trial and potentially a game-changing drug for the management of TTP, which can be very challenging.”
Dr. Brodsky also discussed the Hokusai VTE-Cancer Study, a randomized, open-label, blinded outcome assessment trial that showed the oral factor Xa inhibitor edoxaban was noninferior to subcutaneous dalteparin for the prevention of cancer-associated venous thromboembolism.
With more than 1,000 patients enrolled in 114 centers, the Hokusai VTE-Cancer Study had a primary outcome of the composite of the first recurrent VTE or major bleeding event during follow-up. The primary outcome occurred in 12.8% of patients in the edoxaban group, compared with 13.5% of patients in the dalteparin group (P = .0056 for noninferiority), according to the preliminary published results.
The key question addressed by the trial is whether a newer oral anticoagulant, edoxaban, can substitute for the older, subcutaneously administered low-molecular-weight heparin, dalteparin. The results “confirmed that a newer oral anticoagulant is at least as good and as safe as the low molecular weight heparin,” allowing patients the convenience of an oral therapy, Dr. Brodsky noted.

Obesity-Related Cancer Is on the Rise
Overweight and obesity are associated with an increased risk of 13 types of cancer—and those cancers account for about 40% of all cancers diagnosed in 2014, according to the CDC.
The 13 cancers are meningioma, adenocarcinoma of the esophagus, multiple myeloma, kidney, uterine, ovarian, thyroid, breast, liver, gallbladder, upper stomach, pancreas, and colorectal. About 630,000 people were diagnosed with 1 of those cancers in 2014; 2 in 3 cancers were in adults aged 50 to 74 years. In 2013-2014, about 2 of every 3 American adults were overweight or obese.

Overall, the rate of new cancer cases has been on the decline since the 1990s, the report says, but increases in overweight- and obesity-related cancers “are likely slowing this progress.” Obesity-related cancers (not including colorectal cancer, which declined by 23%) increased by 7% between 2005 and 2014, while the rates of nonobesity–related cancers declined 13%.
Health care providers can help, the CDC says, by counseling patients on healthy weight and its role in cancer prevention, referring obese patients to intensive management programs and connecting patients and their families to community services that give them easier access to healthful food. The National Comprehensive Cancer Control Program (https://www.cdc.gov/cancer/ncccp/index.htm) funds cancer coalitions across the U.S., which include strategies to prevent and control overweight and obesity.

“When people ask me if there’s a cure for cancer, I say, ‘Yes, good health is the best prescription for preventing chronic diseases, including cancer,” said Lisa Richardson, MD, director of CDC’s Division of Cancer Prevention and Control. That means, she says, giving people the information they need to make healthy choices where they live, work, learn, and play.

Eye Hemorrhage Signals Myeloid Leukemia
A 40-year-old man suddenly began to lose vision in his left eye. The retinal exam was normal for the right eye. But the left showed isolated subinternal limited membrane hemorrhage at the fovea along with a white-centered hemorrhage above the fovea.
The patient had no history of trauma or Valsalva retinopathy. His blood pressure was normal as was his blood glucose. However, when bloodwork showed a high total count, increased platelet count, and the peripheral smear indicated myeloid hyperplasia, clinicians at LV Prasad Eye Institute in Hyderabad, India, diagnosed the patient with underlying chronic myeloid leukemia (CML).
A physical examination revealed a palpable spleenomegaly—underscoring the fact, the clinicians note, that when an ophthalmologic finding suggests a systemic disease, a general physical examination will reveal more clinical clues. The patient was referred to an oncologist and started on imatinib for CML.
White-centered or pale-centered hemorrhages are believed to represent an accumulation of leukemic cells or platelet fibrin aggregates, the clinicians say. Blood dyscrasias, such as anemias, leukemia, multiple myeloma, and other platelet disorders may present with similar features. Such hemorrhages are known to resolve spontaneously when the patient is treated for the underlying condition, and the hematologic status improves, the clinicians say. This patient’s hemorrhage gradually resolved over the next month, and his visual acuity improved to 20/20.
Ocular manifestations as a presenting sign of leukemia, especially chronic, are rare, the clinicians say. They note that retinal hemorrhages are one of the “most striking findings” in leukemia, and because they can be directly observed, they provide a “subtle but important clue toward an otherwise asymptomatic disease.” If diagnosed early and treated promptly, patients with CML have a good survival rate.

Rare type of MCL mimics Castleman disease
A rare type of mantle cell lymphoma (MCL) has features that are similar to those of Castleman disease, according to a recent report based on three patient cases.
Lymph node biopsies for these patients initially indicated histologic features consistent with those of plasma cell (PC)-type Castleman disease, reported Takuro Igawa, MD, PhD, of Okayama (Japan) University Graduate School of Medicine, Dentistry, and Pharmaceutical Sciences, and his coauthors. Further work-up, including flow cytometric analysis and cyclin D1 immunostaining, showed features consistent with those of MCL.
“This rare type of MCL can mimic Castleman disease in the clinical setting and upon histological examination,” Dr. Igawa and his colleagues wrote (Pathol Res Pract. 2017 Sep 18. pii: S0344-0338[17]30684-2. doi: 10.1016/j.prp.2017.09.015). “These confusing characteristics can make the diagnosis challenging, and careful flow cytometric analysis is recommended when a histopathological diagnosis is made.”
The patients in the study, all male, were 51, 74, and 81 years of age. Each presented with systemic lymphadenopathy, along with abnormal laboratory findings that according to the investigators are not usually associated with B-cell lymphomas such as MCL, including anemia, polyclonal IgG hypergammaglobulinemia, and elevated levels of C-reactive protein.
In lymph node biopsy specimens, the MCL component was “masked by histological features of PC-type Castleman disease” such as interfollicular plasmacytosis and atrophic germinal centers, the researchers wrote.
However, further pathologic investigations revealed features that were “essential to distinguish these 3 cases of MCL from PC-type Castleman disease,” they added.
In particular, an abnormal B-cell population was found using flow cytometric analysis, while subsequent cyclin D1 immunostaining in all three cases showed abnormal B-cells primarily in the mantle zone that were positive for CD20 and CD5, both typically expressed by MCL, along with SOX11, which is an “excellent diagnostic marker for MCL, including atypical MCL,” the investigators wrote.
These case reports also provide some evidence that interleukin-6 (IL-6), which is thought to be a driver of Castleman disease, might also be implicated in the pathogenesis of this rare MCL variant. the researchers found that all three cases had positive IL-6 staining in the interfollicular areas.
If further studies confirm the role of IL-6 in this rare setting, “specific treatments other than chemotherapy could potentially be used for patients with MCL with features of Castleman disease, such as an anti-IL-6 receptor antibody (tocilizumab), which is already used for patients with Castleman disease,” they said.

FDA Approves Treatment for Chronic GVHD
A treatment for cancer is finding a new purpose in treating another life-threatening condition. The FDA expanded approval of Ibrutinib for treatment of adults with chronic graft versus host disease (cGVHD) after ≥ 1 treatments have failed. Ibrutinib was previously approved for certain indications in treating chronic lymphocytic leukemia, Waldenström macroglobulinemia, and marginal zone lymphoma.
An estimated 30% to 70% of patients who receive hematopoietic stem cell transplantation for blood or bone marrow cancer develop cGVHD.
Ibrutinib , a kinase inhibitor, was tested in a single-arm trial of 42 patients with cGVHD. Most had mouth ulcers and skin rashes; > 50% had ≥ 2 organs affected. Their symptoms had persisted despite standard treatment with corticosteroids. In the study, cGVHD symptoms improved in 67%. For nearly half (48%), the improvements lasted for 5 months or longer.
Common adverse effects include fatigue, bruising, diarrhea, and thrombocytopenia. Serious adverse effects include severe bleeding, infections, and cytopenia.
