Can a simple antibody infusion shield myeloma patients from infections?
NCT ID NCT06976476
First seen Jun 27, 2026 · Last updated Sep 16, 2026 · Updated 4 times
Summary
This study tests whether IgPro20 (HIZENTRA), a concentrated antibody solution given under the skin, can prevent infections in people with multiple myeloma who have low antibody levels due to bispecific antibody therapy. About 100 participants will either receive IgPro20 plus standard care or standard care alone. The goal is to see if infection rates drop over six months.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- IgPro20 (HIZENTRA), a subcutaneous immunoglobulin
- What this could lead to
- If it works, this could provide a way to reduce serious infections in multiple myeloma patients receiving bispecific antibody therapy, improving their quality of life and treatment tolerance.
- What could go wrong
- This is a phase 2 trial with only 100 participants, so results may not apply to all patients. The treatment is preventive, not curative, and carries risks like allergic reactions or infusion site issues.
