Who can take part

AI summary

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults whose multiple myeloma has come back or stopped responding to treatment, after at least 2 earlier lines of treatment. Substudies have different rules about earlier anti-CD38 or BCMA treatment.

Age
18 years or older
Sex
All sexes can join
Disease stage
Relapsed or refractory multiple myeloma with measurable disease (M protein in blood or urine, or abnormal serum free light chains). ECOG performance status 0-1.
Earlier treatment
At least 2 prior lines of treatment, including PIs and IMiDs. Substudies 01 and 06: no anti-CD38 treatment, or a gap of at least 12 months since the last dose. Substudies 02 and 03: no anti-CD38 treatment, or not refractory to it and a gap of at least 6 months. Substudies 04 and 05: earlier anti-CD38 treatment (at least 2 cycles). Anti-BCMA treatment too if available.
