A forest plot composed of dots within bracketed lines represents the hazard ratio and confidence intervals, respectively, of the
PFS results for each patient subgroup and whether the data favor SARCLISA + Pd or Pd alone. These data are also represented in the
HR (95% CI) column. 73/154 89/153 0.60 (0.44, 0.81)

aCytogenetic risk information was missing for 18% of patients in the SARCLISA + Pd arm and 26% of patients in the Pd arm.1

bOf 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.3

Study limitations
Prespecified subgroup analysis; subgroups were not powered to show differences between treatment arms.

ASCT=autologous stem cell transplant; IMiD=immunomodulatory drug; Pd=pomalidomide and dexamethasone; PFS=progression-free survival; PI=proteasome inhibitor; R-ISS=Revised International Staging System.

PFS and rate of ≥VGPR with SARCLISA + Pd in patients with renal impairment*

PFS in patients with renal impairment4

A Kaplan-Meier curve compares the median progression-free survival (mPFS) of patients with renal impairment receiving
                                                    SARCLISA + Pd (mPFS 9.5 months) vs Pd alone (mPFS 3.7 months); HR=0.50 (95% CI: 0.30, 0.85).

≥VGPR in patients with renal impairment4

Two bar charts compare the VGPR and CR outcomes for both treatment arms. ≥VGPR: 33% with SARCLISA + Pd vs 4% with
                                                Pd alone; CR: 5.5% with SARCLISA + Pd vs 2% with Pd alone.

Study limitations
Prespecified subgroup analysis; subgroups were not powered to show differences between treatment arms.

*eGFR <60 mL/min/1.73 m2.3
CR=complete response; eGFR=estimated glomerular filtration rate; mPFS=median progression-free survival; VGPR=very good partial response.
