Summary
This early-stage trial tests a new oral drug called cemsidomide (CFT7455) in about 224 adults with non-Hodgkin's lymphoma or multiple myeloma that has returned or not responded to prior therapies.

What this could lead to
If it works, this could offer a new treatment option for people with blood cancers that have stopped responding to other therapies.
What could go wrong
This is a very early (Phase 1/2) trial, so the drug may not work or may have serious side effects. It is only for people who have already tried other treatments.
