« Return

San Diego, CA, USA – June 14, 2022 – HUYABIO International today announced that the first three patients had been dosed in an ongoing Phase 2 study of HUYABIO’s novel drug for pharmacological cardioversion of atrial fibrillation (AF).

Dr. Mireille Gillings, President, CEO & Executive Chair, said, “We are excited to proceed with dosing AF patients in our Phase 2 trial of HBI-3000. AF is a growing global problem and HUYABIO’s drug is well-positioned to provide a new pharmacological treatment for patients, many of whom would otherwise get electrically cardioverted which can be both stressful and painful.”

The study is evaluating pharmacological cardioversion of acute AF. Cardioversion aims to restore a normal heart rate and rhythm in AF patients and is often done by high energy electrical shock.  The Phase 2 trial HBI-3000-402 is a two-stage, serial cohort dose escalation and expansion study of a single intravenous infusion of HBI-3000 in patients with AF between 2 and 72 hours.

Denis Roy, MD, Montreal Heart Institute and Chief Investigator of the trial, said, “Demonstrating efficacy of HBI-3000 in this trial is an important step towards development of a new therapeutic option to AF patients.”

AF is a serious condition that affects more than 3.5 million patients in the US and 30 million worldwide. There is a significant need for safer and more effective pharmacological interventions to treat AF, as the current standard of care treatments have poor safety and efficacy profiles and the alternative, electrical cardioversion, requires fasting and sedation and can be anxiety provoking for patients.
