First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study looks at how the drug calderasib (MK-1084) behaves in people with moderate or severe kidney problems compared to healthy volunteers. Researchers will measure drug levels in the blood after a single dose to see if kidney function changes how the body processes it. The study also checks for side effects. 34 adults took part, and the results will help guide future dosing for patients with kidney impairment.

Active substance

calderasib (MK-1084) oral tablet

What this could lead to

If successful, this study could help doctors determine the right dose of calderasib for people with kidney problems, making the drug safer and more effective for them.

What could go wrong

This is a very early (Phase 1) study with only 34 participants, so results may not apply to everyone. It only looks at a single dose, not long-term use, and kidney impairment may affect the drug differently than expected.
