CLINICAL NEWS On Location Conference Coverage UPDATES IN MALIGNANT HEMATOLOGY SH Clinical News was on site at this year’s American Society of Clinical Oncology Annual Meeting in Chicago to bring you the latest advances in malignant hematology presented at the meeting, including updates from late-phase clinical trials in leukemia, lymphoma, and myeloma. Here we share some of the practice-changing data, including anti-CD38 antibodies for myeloma, brentuximab vedotin combinations for Hodgkin lymphoma, and treatment strategies for high-risk acute promyelocytic leukemia. We asked some of our hematology experts what caught their eye at this year’s meeting. Here’s what they had to say: Attendees listen to a presentation given by a panel of experts at the ASCO Annual Meeting. Morie A. Gertz, MD Jeremy S. Abramson, MD, MMSc Alan K. Burnett, MD Wendy Stock, MD Mayo Clinic, Rochester, MN “Some of the newly developed drugs – antibodies such as daratumumab, an anti-CD38 monoclonal antibody – show high-level activity in very heavily pretreated patients with multiple myeloma and represent a truly new class of drugs when other therapies fail. We saw new uses for the histone deacetylase inhibitor panobinostat: When used with bortezomib, it improved progression-free survival, and now it has been shown to improve progression-free survival and induce more complete or near responses in patients who are refractory to proteasome inhibitors and immunomodulatory drugs. Moreover, panobinostat, in combination with carfilzomib and lenalidomide, was shown to be a well-tolerated combination.” Massachusetts General Hospital Cancer Center, Boston, MA “The HELIOS trial compared bendamustine/rituximab with bendamustine/rituximab/ibrutinib in patients with relapsed chronic lymphocytic leukemia. The investigators found an increased complete remission rate and a remarkably improved progression-free survival favoring the incorporation of ibrutinib compared with bendamustine/rituximab alone. There is still a big unanswered question in that trial: Since single-agent ibrutinib works great in the relapse setting, what would ibrutinib alone have done in this randomized trial? Also, how much is the bendamustine/ rituximab actually adding? It certainly adds toxicity. Those questions need to be answered in another clinical trial.” CTI BioPharma, Seattle, WA “FLT3 mutations are a significant issue and a significant target in acute myeloid leukemia. It does not prevent patients from reaching remission, but it increases the risk of relapse. Even if they receive transplants, the patients don’t do brilliantly. So, for a long time, there have been a number of FLT3 inhibitors tested. Some have been effective in producing a transient response – mostly by clearing the peripheral blood, but not the bone marrow.” The University of Chicago Medicine, Chicago, IL “There were some very interesting and hopeful abstracts of early-stage trials
