Promising myeloma combo trial halted after just 4 patients
NCT ID NCT06163898
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This very early study tested two drugs, alnuctamab and mezigdomide, together in people with multiple myeloma that had come back or stopped responding to treatment. The goal was to find a safe dose and see if the combination could shrink tumors. However, the trial was stopped early after enrolling only 4 participants, so we have very little information about how well it worked or what side effects occurred.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- alnuctamab and mezigdomide (with dexamethasone)
- What this could lead to
- If it had succeeded, this combination could have offered a new treatment option for people with multiple myeloma that stopped responding to other therapies.
- What could go wrong
- The trial was terminated early with only 4 participants, so we have very little data. It is too early to know if the combination is safe or effective.
