Pembrolizumab plus pomalidomide and dexamethasone for relapsed or refractory multiple myeloma (KEYNOTE-183): subgroup analysis in Japanese patients.
Trial report in International journal of hematology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
The global, randomized, open-label KEYNOTE-183 phase 3 study was closed early after an interim analysis showed unfavorable risk-benefit when pembrolizumab was added to pomalidomide and dexamethasone in patients with relapsed or refractory multiple myeloma (MM). This subgroup analysis reported outcomes in 27 Japanese patients randomly assigned to receive pembrolizumab plus pomalidomide and dexamethasone (n = 15) or pomalidomide and dexamethasone alone (n = 12). Co-primary endpoints were progression-free survival (PFS) and overall survival (OS). After a median (range) follow-up of 9.6 (1.4-15.3) months in Japanese patients, median PFS [6.5 vs 2.8 months; hazard ratio (HR) 0.16 (95% CI 0.03-0.83)] and OS [not reached vs 14.8 months; HR 0.46 (95% CI 0.05-4.20)] seemed to favor the pembrolizumab plus pomalidomide and dexamethasone arm. Objective response rate was numerically higher in this group (47%) than in the pomalidomide and dexamethasone group (25%). The safety profile was consistent with that of the overall study population. No deaths were attributed to a study drug by the investigators. Although adding pembrolizumab to pomalidomide and dexamethasone did not show unfavorable risk-benefit in the Japanese subgroup of KEYNOTE-183, the analysis is limited by short follow-up and small sample size, which affects the generalizability of the results.
