Recruiting at 4 sites Phase 2 Sickle Cell Disease

Sickle Cell Disease study: Senicapoc

Official title Efficacy and Safety of SIL-8301 for Control of Hemolysis in a Uniform Sickle Cell Disease Endotype

ClinicalTrials.gov ID: NCT07282210

What this study is testing

What is Senicapoc?

An investigational oral tablet being studied as a potential chronic treatment for sickle cell disease. It is designed to block the Gardos potassium channel in red blood cells, which may reduce cell dehydration and hemolysis.

Also referred to as SIL-8301.

Plain-language explanation of the investigational treatment. It is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
The study will compare senicapoc to a placebo to see if it improves hemolysis in sickle cell disease patients who still have low hemoglobin despite hydroxyurea.
Who it's for
Adults or children with sickle cell disease, fewer than 2 painful crises per year, a hemolytic complication, hemoglobin 9 g/dL or less, and already taking hydroxyurea.
What's involved
Participants will take a daily pill of senicapoc or a matching placebo while continuing their hydroxyurea treatment for up to 24 weeks.
Time commitment
The trial lasts about 24 weeks and includes regular study visits during that time.
  • Phase 2: a mid-size study of how well it works
  • Time commitment: about 2 years
  • You might receive a placebo (an inactive treatment) instead of the study drug.
