What this research studies

The team will produce clinical-grade Nourexal (Cyclocreatine Phosphate), complete manufacturing controls, and file an IND with the FDA. After regulatory clearance they plan a Phase I safety trial in healthy adult volunteers to study tolerability and basic drug behavior. In animal studies (rats and dogs) Nourexal boosted heart energy, reduced cell injury and inflammation, and allowed much longer cold storage with good recovery after transplant. If the drug proves safe in people, future trials could test giving Nourexal to donors or during heart storage to increase the number of usable donor hearts.

Who could benefit from this research

Good fit: Ideal participants for the planned Phase I trial are healthy adults without major medical problems who can attend clinic visits and follow safety monitoring.

Not a fit: People currently awaiting a transplant will not receive direct benefit from this Phase I safety trial, and those with unstable heart disease are unlikely to qualify.

Why it matters

Potential benefit: If successful, Nourexal could let donated hearts be transported and preserved for much longer, increasing the number of hearts available for transplant.

How similar studies have performed: Similar bioenergetic approaches showed strong protection in animal models, but human testing of Nourexal is novel.
