Clinical Trial Summary

This is a Phase 3 single arm study to investigate efficacy and safety of P1101's rapid titration for adult Japanese patients with PV.


Clinical Trial Description

Eligible patients will be treated with P1101, starting at 250 μg. A starting dose of P1101 is 250 mcg, an intermediate dose is 350 mcg, and a target dose is 500 mcg. As such, subjects will not be exposed to below optimal doses within the first 4 weeks. The maximum recommended single dose is 500 μg injected every two weeks. A primary efficacy endpoint is the rate of phlebotomy-free complete hematologic response (CHR) at Week 24, where CHR is defined as the proportion of patients who have achieved a CHR and have not required phlebotomy in the previous 12 weeks. A responder for the primary endpoint is defined as meeting all of the following criteria at Week 24: Hct (<45%), WBC (≤10 x 10^9/L), and PLT (≤400 x 10^9/L). ;
