Официальное название

A Phase Ib, Multicenter, Randomized, Open-Label, Dose Escalation Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Immunogenicity of 9MW3011 in Patients With Polycythemia Vera

Обзор

The goal of this clinical trial is to assess the safety, tolerability, pharmacokinetics, pharmacodynamics and immunogenicity of 9MW3011 in Chinese patients with Polycythemia Vera（PV）.

Подробное описание

The multiple dose fo the starting dose cohorts will comprise 3 dose cohorts of 8 PV subjects each.In each cohort, subjects will receive 9MW3011 via intravenous infusion.A decision on whether to proceed with case expansion and dose escalation will be based on the safety and PK-PD data.
