Summary

This trial will study sickle cell anemia patients with early stages of kidney disease to see if they are at high risk for the disease progressing.

Who is the study for?
Adults over 18 with Sickle Cell Anemia (SCA) who are at high risk of worsening kidney disease, specifically those with early-stage sickle cell nephropathy and stable medication doses. Participants must not be pregnant or breastfeeding, have no severe infections or recent blood transfusions, and agree to use effective contraception.
What is being tested?
The trial is testing Voxelotor in patients with SCA at an early stage of chronic kidney disease but high risk for progression. It's a forward-looking study where all participants receive the same treatment without a comparison group.
What are the potential side effects?
While specific side effects for this trial aren't listed, Voxelotor may commonly cause headache, diarrhea, abdominal pain, nausea, fatigue, rash and fever. Side effects can vary from person to person.
