Lymphoma

Jeremy S. Abramson, et al.:
CR rates in relapsed/refractory (R/R) aggressive B-NHL treated with the CD19-directed CAR T-cell product JCAR017 (TRANSCEND NHL 001)
The autors of the study conclude that treatment with JCAR017 results in high CR rate in patients with heavily pretreated R/R DLBCL. Relapses can occur despite persistence of JCAR017, suggesting tumor immune evasion mechanisms may contribute to relapse. Observed toxicities are manageable and occurred at rates lower than those reported for other CD19-directed CAR T cell products.
 
David Jacob Andorsky, et al.:
Phase IIIb randomized study of lenalidomide plus rituximab (R2) followed by maintenance in relapsed/refractory NHL: Analysis of patients with double-refractory or early relapsed follicular lymphoma (FL)
The autors of the study conclude that R2 followed by maintenance showed favorable activity and tolerable safety profiles in FL patients who are double-refractory or had early relapse ( < 2 years) after initial diagnosis. Enrollment in MAGNIFY is ongoing.
 

Multiple Myeloma

Frank (Xiaohu) Fan, et al.:
Durable remissions with BCMA-specific chimeric antigen receptor (CAR)-modified T cells in patients with refractory/relapsed multiple myeloma
The autors of the study conclude that a 100% objective response rate (ORR) to LCAR-B38M CAR-T cells was observed in refractory/relapsed myeloma patients. 18 out of 19 (95%) patients reached CR or near CR status without a single event of relapse in a median follow-up of 6 months. The majority (14) of the patients experienced mild or manageable CRS, and the rest (5) were even free of diagnosable CRS. Based on the encouraging safety and efficacy outcomes, we believe that our LCAR-B38M CAR-T cell therapy is an innovative and highly effective treatment for multiple myeloma.
 
Graham H. Jackson, et al.:
Lenalidomide induction and maintenance therapy for transplant eligible myeloma patients: Results of the Myeloma XI study
The autors of the study conclude that CRD was associated with deeper responses than CTD, and with a PFS and OS benefit. The best outcomes were associated with Len induction plus Len maintenance. Our findings support continuing Len therapy through induction until disease progression.
 
Sundar Jagannath, et al.:
Impact of post-autologous stem cell transplant (ASCT) maintenance therapy on outcomes in patients (Pts) with newly diagnosed multiple myeloma (NDMM) using the large prospective community-based Connect MM registry
The autors of the study conclude that in ASCT-eligible NDMM pts, PFS and OS improved with LEN MT vs No MT and appeared to be independent of induction regimen. Preliminary analysis of 2nd PFS suggests no impact on the efficacy of 2nd line therapy. These data from a largely community-based setting confirm results from randomized phase III trials.
 
Philip L. McCarthy, et al.:
CALGB/ECOG 100104 (Alliance) study: Lenalidomide (LEN) vs placebo (PBO) maintenance (maint) after stem cell transplant (SCT) for patients (pts) with multiple myeloma—Overall survival (OS) and progression-free survival (PFS) adjusted for treatment (tx) crossover (XO)
The autors of the study conclude that adjusting for the potential diluting effects of XO reduced median OS and PFS with PBO, and improved the Tx effect in the ITT analyses for OS and PFS for LEN vs PBO maint after SCT. The statistical significance of the ITT analyses was maintained throughout.
 
Brigitte Pegourie, et al.:
Evaluation of an oral direct anti-Xa anticoagulant, apixaban, for the prevention of venous thromboembolism in patients with myeloma treated with IMiD* compounds: A pilot study (MYELAXAT)
The autors of the study conclude that referring to the incidence of thromboembolic events in Carrier’s meta-analysis, and to hemorrhagic events in medical patients recieving apixaban in primary VTE prophylaxis, apixaban used in a preventive scheme seems to be efficient and safe in preventing VTE in myeloma patients treated with IMiD* compounds.

AML

Eytan M. Stein, et al.:
Enasidenib in mutant-IDH2 relapsed or refractory acute myeloid leukemia (R/R AML): Results of a phase I dose-escalation and expansion study
The autors of the study conclude that Enasidenib was well tolerated, induced CRs, and was associated with OS of >9 mos in pts who had failed prior AML therapies. Differentiation of myeloblasts, not cytotoxicity, appears to drive the clinical efficacy of enasidenib.
