Matching-adjusted Indirect Comparisons of the Efficacy and Safety of Acalabrutinib Versus Other Targeted Therapies in Relapsed/Refractory Mantle Cell Lymphoma.

The objective of this analysis was to compare the efficacy and safety of acalabrutinib versus other targeted therapies employed for the treatment of relapsed/refractory MCL by using matching-adjusted indirect comparisons. METHODS: Individual data from 124 patients treated with acalabrutinib in the Phase II ACE-LY-004 trial were adjusted to match average baseline characteristics of populations from studies using alternative targeted treatment regimens for relapsed/refractory MCL (for monotherapy: ibrutinib, bortezomib, lenalidomide, and temsirolimus; for combination therapies: ibrutinib + rituximab, bendamustine + rituximab, and lenalidomide + rituximab). Patient populations were matched on age, sex, race, Eastern Cooperative Oncology Group performance status, Simplified MCL International Prognostic Index score, tumor bulk, lactate dehydrogenase concentration, extranodal disease, bone marrow involvement, and number of previous treatment regimens. Outcomes assessed included overall response rate (ORR), complete response (CR) rate, overall survival (OS), progression-free survival (PFS), and adverse events. FINDINGS: After matching, acalabrutinib was associated with significant increases in ORR and CR rate (estimated treatment difference [95% CI]) versus ibrutinib (ORR, 9.3% [0.3-18.3]; CR, 14.9% [5.4-24.3]), bortezomib (ORR, 50.6% [40.2-61.0]; CR, 18.8% [9.1-28.5]), lenalidomide (ORR, 38.1% [27.1-49.1]; CR, 43.5% [34.8-52.3]), and temsirolimus (ORR, 40.7% [...
