CeleCor Therapeutics Advances Revolutionary Heart Attack Treatment with Successful Phase 3 Trial

CeleCor Therapeutics has taken a significant step forward in the treatment of severe heart attacks with the successful completion of its pivotal CeleBrate phase 3 trial. The company's investigational antiplatelet therapy, zalunfiban, has shown promising results in reducing the risk of larger heart attacks and associated complications when administered at the first point of medical contact.

Zalunfiban: A Game-Changer for STEMI Heart Attack Treatment

Zalunfiban, designed to block the glycoprotein IIb/IIIa receptor, is administered as a subcutaneous injection by first responders and emergency departments. The drug's rapid onset of action, reaching maximal effect within 15 minutes, addresses a critical gap in current heart attack care.

Dr. Arnoud WJ van 't Hof, the principal trial investigator, stated that zalunfiban has the potential to "transform how we treat STEMI heart attacks." This is particularly significant for patients in rural areas or those without immediate access to hospitals equipped for percutaneous coronary intervention (PCI).

CeleBrate Trial Results: Efficacy and Safety

The CeleBrate study, presented at the American Heart Association's annual scientific sessions and published in The New England Journal of Medicine Evidence, demonstrated impressive outcomes:

• 21% reduction in the risk of larger heart attacks or those leading to death, stroke, heart failure, or other risks compared to placebo
• Higher levels of blood flow to the heart when administered at the first point of medical contact
• No significant increase in major bleeding, addressing a key safety concern

Dr. Barry S. Coller, vice president for medical affairs at Rockefeller University and co-founder of CeleCor, explained that zalunfiban's short duration of action – wearing off in about two hours – is strategically timed to coincide with hospital interventions.

Addressing a Critical Need in Cardiovascular Care

With approximately 750,000 people in the U.S. experiencing STEMI heart attacks annually, zalunfiban addresses a pressing medical need. Current statistics reveal that 83% of U.S. STEMI patients transferred to PCI centers from other hospitals do not receive timely treatment, resulting in a three- to fourfold higher death rate.

CeleCor Therapeutics, founded in 2017 with the sole purpose of improving STEMI heart attack treatment, is now poised to file for FDA approval in early 2026. This development marks a potential paradigm shift in emergency cardiac care, offering hope for improved outcomes in the critical minutes following a severe heart attack.
