What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to test the long-term safety and tolerance of pociredir, a treatment for people with sickle cell disease (SCD). Participants will take pociredir daily for up to four years to assess their ability to handle the treatment over time. This trial targets individuals who previously experienced benefits from pociredir in an earlier study. Those treated with pociredir before and found it beneficial may be suitable candidates for this trial. As a Phase 2 trial, the research focuses on measuring the treatment's effectiveness in an initial, smaller group of people.

Will I have to stop taking my current medications?

You may need to stop taking hydroxyurea, but you can continue crizanlizumab and L-glutamine if you've been on a stable dose for at least 6 months. The protocol doesn't specify about other medications, but you should avoid certain drugs that affect liver enzymes.

Is there any evidence suggesting that pociredir is likely to be safe for humans?

Previous studies have shown that pociredir is safe for people with severe sickle cell disease (SCD). Many patients tolerated the treatment well, and serious side effects were rare. Research indicates that pociredir is generally well-tolerated at various doses, including 12 mg. Some studies have even demonstrated promising efficacy, enhancing its positive safety record. Additionally, the FDA has granted pociredir Fast Track and Orphan Drug Designation for treating SCD, supporting its safety and potential benefits. Overall, the evidence suggests that pociredir is a generally safe option for those considering the treatment.12345

Why do researchers think this study treatment might be promising for sickle cell disease?

Unlike the standard treatments for sickle cell disease, which often include hydroxyurea and blood transfusions, Pociredir is unique because it is an oral medication taken once daily. Researchers are excited about Pociredir because it offers a new mechanism of action, potentially targeting the underlying causes of sickle cell disease more directly. This could mean fewer side effects and more effective management of the condition, offering hope for improved quality of life for patients.

What evidence suggests that pociredir might be an effective treatment for sickle cell disease?

Research has shown that pociredir, the investigational treatment in this trial, can increase fetal hemoglobin (HbF) levels in people with sickle cell disease (SCD). One study found that everyone taking a 20 mg dose experienced an HbF increase of at least 6.5%. More than half of the participants reached HbF levels of 20% or higher, which correlates with fewer symptoms of sickle cell disease. Higher HbF levels can help prevent the formation of sickle-shaped cells, reducing pain and other complications. Previous studies have also found pociredir to be safe and well-tolerated. Overall, early findings suggest that pociredir could significantly improve the health of those with SCD.16789

Are You a Good Fit for This Trial?

This trial is for people with sickle cell disease or thalassemia who are at least 18 years old and have already completed a previous study (6058-SCD-101) showing benefit from pociredir. Participants must be able to follow study procedures.
