Clinical Trial Summary

The purpose of this study is to evaluate the safety, tolerability, efficacy, pharmacokinetics and pharmacodynamics of osivelotor.


Clinical Trial Description

This is a three-part, multicenter, Phase 2/3 study of orally administered osivelotor in participants with sickle cell disease (SCD). Part A will evaluate the safety, tolerability, and efficacy of osivelotor in adult participants with SCD to determine an optimal dose. Part B will evaluate the efficacy of osivelotor versus placebo in adult and adolescent participants with SCD for 48 weeks. Part C will evaluate the pharmacokinetics (PK) and safety of single and multiple doses (MD) of open-label single arm osivelotor administered to pediatric participants. ;
