Immune Thrombocytopenia clinical trials at University of California Health

This is a randomized, double-blind study of rilzabrutinib in participants with persistent or chronic ITP, with an average platelet count of <30,000/μL (and no single platelet count >35,000/μL) on two counts at least 5 days apart in the 14 days before treatment begins. Participants will receive rilzabrutinib or placebo 400mg twice daily. For each participant, the study will last up to 60 weeks from the start of the Screening Period to the End of Study (EOS) visit. This includes Screening (up to 4 weeks) through a 12 to 24-week Blinded Treatment Period followed by a 28-week Open-Label Period. Followed by a 4-week post dose follow-up. For adult participants, the maximum duration of the long-term extension (LTE) period will be 12 months from the date of the last adult participant to enter the LTE. For pediatric participants, the maximum duration of the LTE period will be 12 months from the date of the last pediatric participant to enter the LTE.
