Study Summary

This was a 2 part (Part A and B) adaptive, open-label, dose-finding study of PRN1008 in patients with ITP who are refractory or relapsed with no available and approved therapeutic options, with a platelet count \<30,000/μL on two counts no sooner than 7 days apart in the 15 days before treatment begins. The dose-finding portion of the study was completed. Part B treatment dose was 400 mg twice daily.

Primary Outcome

The percentage of participants who achieved 2 or more consecutive platelet counts, separated by at least 5 days, of \>=50,000/ microliter (μL) and an increase of platelet count of \>=20,000/μL from baseline, by starting dose level and overall, without use of rescue medication in the 4 weeks prior to the latest elevated platelet count. 95% confidence interval (CI) was based on the Clopper-Pearson method. The average of the 2 screening results and the Cycle 1 Day 1 result were used as the baseline
