New hope for Hard-to-Treat myeloma: QLS32015 enters phase 3 trial
NCT ID NCT07138209
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests a new drug called QLS32015 against two standard treatment combinations (pomalidomide with dexamethasone or selinexor with dexamethasone) in 228 people with multiple myeloma that has relapsed or is refractory. The main goal is to see if QLS32015 can delay cancer progression better than the current options. Participants are randomly assigned to receive either the new drug or one of the standard regimens.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- QLS32015
- What this could lead to
- If successful, QLS32015 could offer a new treatment option for people with multiple myeloma that has returned or not responded to prior therapy.
- What could go wrong
- This is an early-stage Phase 3 trial, so results are not yet known. The new drug may not be more effective or safer than existing treatments, and side effects are possible.
