New Two-Drug combo targets Hard-to-Treat myeloma in early trial
NCT ID NCT06215118
First seen Jun 27, 2026 · Last updated Sep 16, 2026 · Updated 2 times
Summary
This early-stage study is testing whether a combination of two drugs—elranatamab (given as a shot) and iberdomide (taken as a pill)—is safe and tolerable for people with multiple myeloma that has returned or stopped responding to prior treatments. The trial will enroll about 87 participants and has two parts: first to check safety, then to find the right dose. It is not a cure, but if successful, it could provide a new way to control this blood cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- elranatamab (a drug that helps the immune system attack cancer cells) and iberdomide (a pill that targets cancer cells)
- What this could lead to
- If this combination proves safe and effective, it 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 a very early (Phase 1) study with only 87 participants, so it is primarily testing safety and dosing. The combination may not work well or could cause serious side effects. It is not a cure and will likely require ongoing treatment.
