Abstract

INTRODUCTION: Pomalidomide (Pom) has demonstrated synergistic antiproliferative activity in combination regimens as a result of its distinct anticancer, antiangiogenic, and immunomodulatory effects. This review aimed to compare outcome measures of different Pom regimens for relapsed/refractory multiple myeloma.

METHODS: A comprehensive literature search identified a total of 1374 studies. Thirty-five studies assessing 4623 subjects met the inclusion criteria: phase 2/3 trial, ≥ 2 prior lines of therapy, and clearly documented efficacy outcomes like overall response rate (ORR), overall survival, and progression-free survival. Statistical analyses for meta-analysis was performed by CMA version 3 and Cochrane Q statistics (P < .05 considered significant, I

RESULTS: Pooled analysis showed ORR 47.1% across all Pom-based (2- and 3-drug) regimens. Stratified analysis for efficacy outcomes (pooled ORR [%] and mean progression-free survival [months]) are reported. With doublet regimen, Pom with low-dose dexamethasone (LoDex) was the most common regimen (35.7%, 6.1 months), and overall survival was 14.37 months. With triplet regimens, pooled ORR was 61.9% (I

CONCLUSION: Three-drug Pom regimens yielded double the response rates compared to Pom + LoDex (pooled ORR, 61.9% vs. 35.7%), with bortezomib + Pom + LoDex and carfilzomib-Pom + LoDex demonstrating better outcomes than other regimens.
