LYMPHOMAS

When John P. Leonard, MD, spoke at the American Society of Hematology inaugural meeting on Hematologic Malignancies about mantle cell lymphoma (MCL), he balanced his enthusiasm about the emerging benefits that tumor profiling brings to this disease with an acknowledgement that many important questions about mantle cell lymphoma remain unanswered.

The therapeutic palette for Hodgkin Lymphoma is growing, along with improvements in survival and cure rates.

The antibody-drug conjugate (ADC) brentuximab vedotin (Adcetris) was recently approved by the FDA as a consolidation therapy following autologous stem cell transplantation (ASCT) in patients who have Hodgkin lymphoma and are at risk of relapse or progression.

The development of novel targeted drugs, such as brentuximab vedotin (Adcentris), against discrete cell surface proteins, such as CD30, has awakened a new way of thinking about targeted cancer biology

Infusions of CTL019, a CAR-modified T-cell therapy against CD19, achieved durable responses and showed an acceptable safety profile in heavily pretreated patients with CD19-positive DLBCL, MCL, and FL.

Treatment with the PD-1 inhibitor nivolumab demonstrated durable objective response rates in patients with classical Hodgkin lymphoma, diffuse large B-cell lymphoma, and follicular lymphoma.

Catherine M. Diefenbach, MD, assistant professor, Department of Medicine, NYU Langone Medical Center, discusses the efficacy of two doses of polatuzumab vedotin (POV) in patients with relapsed/refractory (RR) follicular lymphoma (FL).

The 1.8-mg/kg dose of polatuzumab vedotin is as effective as the 2.4-mg/kg dose on the endpoint of progression-free survival in patients with relapsed/refractory non-Hodgkin lymphoma while improving tolerability, according to a pooled analysis of phase I and phase II clinical studies.

Treatment with obinutuzumab in combination with bendamustine nearly doubled progression-free survival compared with bendamustine alone in patients with rituximab-refractory indolent non-Hodgkin lymphoma.
