Summary

This study tests two drugs, mezigdomide and elranatamab, together in people with multiple myeloma that has come back or stopped responding to prior treatments. The goal is to find the safest dose and see if the combination can shrink tumors. About 62 adults will take part in this early-stage trial.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
mezigdomide and elranatamab (with dexamethasone)
What this could lead to
If successful, this combination could offer a new treatment option for people with multiple myeloma that has returned or stopped responding to other therapies.
What could go wrong
This is an early-phase trial with only 62 participants, so results may not apply to everyone. The drugs may cause serious side effects or fail to control the cancer.
