Trial Design

The first phase 3 trial evaluating a CD38-directed monoclonal antibody + Pd vs Pd alone

A multicenter, open-label, randomized, phase 3 study in patients with relapsed refractory multiple myeloma1

Patients with relapsed refractory multiple myeloma who received at least 2 prior therapies, including lenalidomide and a PI

Randomized 1:1 (N=307)

SARCLISA + Pd
(n=154)

Pd
(n=153)

  • SARCLISA 10 mg/kg was administered as an IV infusion weekly in the first cycle and every 2 weeks thereafter
  • Treatment administered in 28-day cycles until disease progression or unacceptable toxicity

Primary endpoint: PFS

Key secondary endpoints: ORR, OS

  • Pomalidomide 4 mg was taken orally once daily from day 1 to day 21 of each 28-day cycle. Low-dose dexamethasone (orally or IV) 40 mg (20 mg for patients ≥75 years of age) was given on days 1, 8, 15, and 22 for each 28-day cycle1
