A Phase 2b Dose Finding Study of RMC-035 in Participants Undergoing Open-chest Cardiac Surgery

Phase 2
Recruiting
Conditions
Kidney Injury Following Open-Chest Cardiac Surgery
Interventions
Drug: Placebo
Registration Number
NCT06475274
Lead Sponsor
Guard Therapeutics AB
Brief Summary

The goal of this clinical trial is to identify the optimal dose of RMC-035 for protection of long-term renal function in adult patients undergoing cardiac surgery who are at high risk of kidney injury. It will also learn about the safety of RMC-035. The main question it aims to answer is:

* Does RMC-035 protect the function of kidneys after surgery?

* Is RMC-035 safe?

Researchers will compare RMC-035 in high dose, RMC-035 in low dose and placebo to see if

* Kidney function better for participants treated with any of the RMC-035 doses?

* What medical problems do participants have when receiving RMC-035?

Participants will

* Receive 3 doses of RMC-035 or placebo: at the beginning of surgery, end of surgery and 24h after surgery

* Have extra checkups and tests during their hospital stay

* Visit the clinic at two extra occasions at 60 days and 90 days after surgery for checkups and tests
