aCytogenetic risk information was missing for 18% of patients in the SARCLISA + Pd arm and 26% of patients in the Pd arm. Of the patients who had high-risk chromosomal abnormalities at study entry, del(17p), t(4;14), and t(14;16) were present in 12%, 8%, and 2% of patients, respectively. High-risk cytogenetic status was defined by the presence of ≥1 of del(17p), t(4;14), or t(14;16), and was considered positive if present in ≥30% of plasma cells for t(4;14) and t(14;16), and in ≥50% of plasma cells for del(17p). Gain(1q21) was considered positive if ≥3 copies of 1q21 were present in ≥30% of analyzed cells.1,3,4
Study limitations
Prespecified subgroup analysis; subgroups were not powered to show differences between treatment arms.
PFS and ORR in the intent-to-treat population4
mPFS: 11.53 months with SARCLISA + Pd (n=154) vs 6.47 months with Pd alone (n=153), HR=0.596 (95% CI: 0.44, 0.81; P=0.0010)
ORR: SARCLISA + Pd, 60.4% (95% CI: 0.52, 0.68); Pd, 35.3% (95% CI: 0.28, 0.43)
ASCT=autologous stem cell transplant; mPFS=median progression-free survival; ORR=overall response rate; PFS=progression-free survival; PI=proteasome inhibitor; R-ISS=Revised International Staging System.
