A median 19-month follow-up of the JULIET trial—a single-arm, open-label, multicenter, global, pivotal phase 2 trial of the chimeric antigen receptor-T cell therapy tisagenlecleucel directed against CD19-expressing B cells—has found a 40% complete response and a manageable safety profile in adult patients with relapsed/refractory (R/R) diffuse large B-cell lymphoma (DLBCL).

Two-year maintenance therapy with ixazomib led to a 39% improvement in progression-free survival compared with placebo in patients with newly diagnosed multiple myeloma who achieved a partial response to induction treatment with a proteasome inhibitor and/or an immunomodulatory agent following autologous stem cell transplant.

Concurrent treatment with ibrutinib and the CD19-targeted chimeric antigen receptor T-cell therapy JCAR014 was well tolerated and led to an overall response rate of 83% in patients with relapsed or refractory chronic lymphocytic leukemia.

Although CAR T-cell therapies have proved successful in certain hematologic malignancies, efforts to employ similar strategies in solid tumors have been challenging. Investigators are working on different forms of adoptive cell therapy in solid tumors and early signs are promising.
