About Vapendavir

Vapendavir is an investigational oral medicine in development by Altesa BioSciences. Vapendavir demonstrated efficacy in patients with COPD by improving symptoms, reducing duration of illness and viral load, and maintaining small airway function after rhinovirus challenge. Vapendavir is now in late-stage clinical development and, if approved, has the potential to prevent the most common cause of COPD exacerbations, improve quality of life, and generate significant reductions in healthcare costs.

About the CARDINAL Study

The CARDINAL clinical trial is a Phase 2b multinational, randomized, placebo-controlled study in COPD patients experiencing rhinovirus infections that will enroll 900 people with COPD across the US and UK Participants will be closely monitored over time and, upon confirmed rhinovirus infection, will be randomized to receive one of two doses of vapendavir or placebo. The trial’s primary objective is to assess improvement in respiratory symptoms using established patient-reported outcomes, with additional endpoints evaluating time to symptom resolution, quality of life, healthcare resource utilization, and lung function.
