What this trial studies

This study aims to evaluate the safety and effectiveness of baricitinib in reducing albumin levels in the urine of African American/Blacks suffering from APOL1-associated focal segmental glomerulosclerosis (FSGS) and non-diabetic chronic kidney disease due to hypertension. Participants will be adults aged 18-70 with specific high-risk APOL1 genotypes and diagnosed kidney conditions. The study will involve a comparison between the drug and a placebo to assess its impact on kidney function and disease progression.

Who should consider this trial

Good fit: Ideal candidates are African American/Blacks aged 18-70 with high-risk APOL1 genotypes and diagnosed FSGS or hypertension-related chronic kidney disease.

Not a fit: Patients with diabetes, HIV, sickle cell disease, or those with certain severe health conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve kidney health and reduce complications for patients with APOL1-associated kidney diseases.

How similar studies have performed: Other studies have shown promise in targeting APOL1-related kidney diseases, but this specific approach using baricitinib is relatively novel.
