Akshat Jain: NEJM Group Study Demonstrates Platelet Responses in ITP Treated with Mezagitamab
Akshat Jain, Hematology Pediatric Workforce Task Force at American Society of Hematology, shared a post on LinkedIn about a recent article by David J. Kuter et al. published in NEJM, adding:
“Exciting new data in ITP treatment : a phase 2 NEJM Group study found that mezagitamab, a CD38-targeting antibody, produced rapid and sustained platelet responses, with the highest dose showing a platelet response in 91% of patients by week 16 and a safety profile similar to placebo.
Why this matters: ITP remains an area of major unmet need, and this therapy may represent a true shift from symptom control toward disease modification by targeting the immune cells driving platelet destruction.
If confirmed in phase 3, mezagitamab could meaningfully change the treatment landscape for patients who do not respond well to current options.
600 mg dose achieving a platelet response in 91% of patients by week 16 and a tolerability profile comparable to placebo.
This is especially important in ITP, where many patients still have limited durable responses to existing therapies.
By targeting CD38-expressing immune cells, mezagitamab may offer a more disease-modifying approach rather than just temporary platelet support.”
