Hundreds of clinical trials are rolled out around the world monthly, and many of them are designed to specifically uncover and manage the medical needs of people with sickle cell disease and trait. We keep an updated list of these global studies here, so you don’t have to go searching for them. There might be active study recruitment and enrollment happening at a site near you. Explore the list below to see the different types of studies, and use the navigation options on the left to get as specific as you would like.
This first in human study is designed to evaluate the safety, tolerability, pharmacokinetics (PK), and food effect of GBT021601, a hemoglobin S (HbS) polymerization inhibitor, in healthy participants.

Phase 1
The trial of IV arginine therapy in children with Vaso-occlusive painful episodes (VOE) in sickle cell disease (SCD) is designed to further knowledge on efficacy and safety of the therapy.
This clinical trial studies the effect of pre-transplant immunosuppression (PTIS) and donor stem cell transplant in treating patients with severe blood diseases (hemoglobinopathies).
The purpose of this study is to assess the antibody response to COVID-19 vaccination in a cohort of patients with sickle cell disease (SCD) and to assess vaccine and SCD related complications around the time of vaccination.
The purpose of this study is to evaluate the efficacy, safety and tolerability of treatment with EDIT-301 in adult subjects with severe sickle cell disease (SCD).

Phase 4
This is a non-randomized, open-label, multi-site, single-dose, Phase 3 study in approximately 35 adults and pediatric subjects ≥2 and ≤50 years of age with sickle cell disease (SCD).
This Phase 1 first-in-human, first-in-patient, single ascending dose and multiple dose study will be a randomized, double-blind, placebo-controlled investigation of the safety, tolerability, and pharmacokinetics of PF-07209326 in healthy participants and participants with sickle cell disease.
This clinical trial is a Phase 2/3 study that will evaluate the efficacy and safety of etavopivat and test how well etavopivat works compared to placebo to improve the amount of hemoglobin in the blood and to reduce the number of vaso-occlusive crises (times when the blood vessels become blocked and cause pain).

Phase 2/Phase 3
The purpose of the study is to assess the safety and tolerability of AG-946 in healthy volunteers after oral administration of single ascending doses (SAD) and multiple ascending doses (MAD) of AG-946 over 14 or up to 28 days of dosing, and to identify a range of doses that are safe and pharmacologically active in participants with sickle cell disease.
