Kidney health may change how body handles experimental drug ESK-001
NCT ID NCT06962774
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This completed phase 1 study looked at how different levels of kidney function affect the way the body processes a single dose of ESK-001, an experimental drug. Sixteen participants with healthy kidneys or mild, moderate, or severe kidney impairment each took one oral dose. Researchers measured drug levels in the blood and monitored for side effects to understand how the kidneys impact the drug's breakdown and removal.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- ESK-001
- What this could lead to
- If successful, this study will help determine the right dose of ESK-001 for people with kidney problems, making future treatments safer and more effective.
- What could go wrong
- This is a very early, small study (16 people) focused on drug levels, not on treating any disease. It only looks at a single dose, so long-term effects or benefits are unknown.

Key Inclusion Criteria for All Participants: * Body mass index between 18.0 and 40.0 kg/m2 Key Inclusion Criteria for Participants with Renal Impairment: * Diagnosis of chronic, stable renal function in the 6 months prior to dosing, as determined by the investigator, based on medical history or eGFR, and not requiring dialysis Key Exclusion Criteria for All Participants: * History of stomach or intestinal surgery or resection that would potentially alter absorption and/or excretion of orally administered drugs (uncomplicated appendectomy, cholecystectomy, and hernia repair are allowed).
