Overview
Brief Summary
This is a phase Ib, randomized, double-blind, placebo-controlled, multiple ascending dose study . The objectives of the study are to evaluate the safety , tolerability, pharmacokinetics(PK), pharmacodynamics(PD), and immunogenicity of 9MW3011 in patients with non-transfusion-dependent β- thalassemia .
Detailed Description
A total of 40 subjects diagnosed with non-transfusion-dependent β-thalassemia will be enrolled in this study and assigned into four dosage cohorts. In each cohort, subjects will be randomized in a 4:1 ratio to receive 9MW3011 or placebo via intravenous infusion.

Eligibility Criteria
Inclusion Criteria
- •Male and female subjects aged 18 to 65 years (inclusive)
- •Subject must have a documented genetic diagnosis of β-thalassemia or hemoglobin E/ β-thalassemia
- •Subjects must meet the criteria for non-transfusion-dependent thalassemia
- •Subjects must have a baseline hemoglobin level between 70-100 g/L(inclusive), based on 2 consecutive measurements taken at least 1 week apart within 4 weeks before randomization
- •Subjects must have evidence of iron overload during screening
- •Subject must have performance status: Eastern Cooperative Oncology Group (ECOG) performance score of 0 to 1
- •Subjects must fully understand the study procedures and methods, voluntarily participate in the trial, and sign an informed consent form
Exclusion Criteria
