Efficacy and Safety of P1101 in Polycythemia Vera Patients for Whom the Standard of Treatment is Difficult to Apply

Polycythemia Vera (PV) Clinical Trial

Official title: Phase 2 Single Arm Study of Efficacy and Safety of P1101 for Polycythemia Vera (PV) Patients for Whom the Current Standard of Treatment is Difficult to Apply

Status Completed

Clinical Trial Summary

This is a Phase 2 single arm study to investigate efficacy and safety of P1101 for adult Japanese patients with PV.

Clinical Trial Description

Eligible patients will be treated with P1101, starting at 100 μg (or 50 μg in patients under another cytoreductive therapy). The dose should be gradually increased by 50 μg every two weeks (in parallel, other cytoreductive therapy should be decreased gradually, as appropriate) until stabilization of the hematological parameters is achieved (hematocrit <45%, platelets <400 x 10^9/L and leukocytes <10 x 10^9/L). The maximum recommended single dose is 500 μg injected every two weeks.

At week 36 (month 9) and week 52 (month 12), the primary study endpoint, phlebotomy-free CHR, will be analyzed. After completion of the 52-week study duration, provision and administration of P1101, collection of the long-term follow up information (blood parameters, molecular and cytogenetic data, safety parameters and as also the optional bone marrow data) will be continued until the drug becomes commercially available for all study subjects.. ;
