A dizzying array of new chimeric antigen receptor (CAR) T-cell therapies targeting the B-cell maturation antigen (BCMA) designed specifically for the treatment of multiple myeloma was presented at the 2018 American Society of Hematology (ASH) annual meeting. BCMA-targeted CAR T-cell therapies are designed to improve T-cell persistence, depth of response, and tolerability. Response rates reported at ASH 2018 range from 70% to 100%, depending on the patient population and the use of previous regimens.

San Diego, CA—A chimeric antigen receptor (CAR) T-cell therapy that targets CD19 and CD22 molecules has demonstrated safety and efficacy, in patients with relapsed or refractory B-cell precursor acute lymphoblastic lymphoma (ALL), with response rates consistent with CAR T-cell therapies that target CD19 alone.

San Diego, CA—Patients with relapsed, refractory, or high-risk hematologic malignancies obtained durable benefits with the combined checkpoint inhibition with nivolumab (Opdivo) and ipi­limumab (Yervoy) as consolidation therapy after stem-cell transplant, according to results of a small prospective study presented at ASH 2018.

San Diego, CA—A 2-year duration of combination immunotherapy with ven­etoclax (Venclexta) and rituximab (Ri­tuxan) improved survival compared with standard-of-care chemoimmunotherapy combination with bendamustine (Ben­deka) plus rituximab in patients with relapsed or refractory chronic lymphocytic leukemia (CLL), according to follow-up data from the MURANO clinical trial presented at ASH 2018. Early results were first presented at ASH 2017.

San Diego, CA—Although chimeric antigen receptor (CAR) T-cell therapy has achieved remarkable long-lasting remissions in B-cell malignancies, in approximately 60% of the cases, the initial response wanes over time because of “immune exhaustion.”

San Diego, CA—Longer-term follow-up of 2 large pivotal clinical trials in B-cell malignancies has demonstrated continuing remissions after chimeric antigen ­receptor (CAR) T-cell therapy: the ELIANA study in pediatric patients and young adults with relapsed or refractory B-acute lymphoblastic leukemia (B-ALL) and the JULIET study in adult patients with diffuse large B-cell lymphoma (DLBCL). Both updates were presented at a press conference at ASH 2018.

San Diego, CA—Zanubrutinib, a highly specific and irreversible next-generation Bruton’s tyrosine kinase (BTK) inhibitor, exhibited excellent activity in a single-arm, open-label multicenter phase 2 clinical trial of patients with relapsed or refractory mantle-cell lymphoma (MCL). Early study results were reported at ASH 2018.

San Diego, CA—The BCL2 Gly101Val mutation is the first genomic alteration to be identified as responsible for resistance to venetoclax (Venclexta), a potent and effective medication indicated for the treatment of chronic lymphocytic leukemia (CLL). The BCL2 Gly101Val mutation is unique to CLL and so far has not been described in other cancers.
