XYRA Secures FDA Consensus on Budiodarone Approval Path for Atrial Fibrillation Treatment

XYRA LLC, a biopharmaceutical firm focused on developing treatments for cardiac rhythm disorders, has announced a significant agreement with the FDA regarding the approval process for its drug budiodarone. This medication is intended for the long-term management of atrial fibrillation (AF), a common cardiac arrhythmia affecting millions worldwide.

The FDA has recognized that patients with non-permanent AF, particularly those with long episodes of atrial fibrillation lasting over 5.5 hours, are at an increased risk of stroke and heart failure. To address this, the FDA and XYRA have agreed on two pivotal studies necessary for the drug's approval. The first study is an open-label, long-term dosing study that will use FDA-approved wearable AF monitoring devices to adjust dosages and ensure the safety and effectiveness of budiodarone. The second study is a six-month, double-blind, randomized controlled trial comparing different doses of budiodarone to a placebo in patients with symptomatic non-permanent AF.

Budiodarone stands out as a potentially superior mixed ion channel blocker with a shorter half-life than its predecessor, amiodarone, and without evidence of accumulation in studies. It is designed to control AF symptoms, eliminate long episodes of atrial fibrillation, reduce the overall burden of AF, and maintain a normal heart rhythm.

The FDA's decision to forego a large, long-term cardiovascular outcomes study for budiodarone reflects the drug's improved design and the absence of EKG changes at therapeutic doses. If budiodarone continues to show safety and efficacy in the pivotal AF studies and a short-term study involving ventricular tachycardia patients with an implantable cardiac defibrillator, it may receive approval under International Conference on Harmonization guidelines.

Peter Milner, MD, FACC, and managing member of XYRA, expressed gratitude to the FDA for the guidance received and emphasized the importance of integrating wearable AF monitoring devices into the drug's development to ensure patients receive the lowest effective dose.

Atrial fibrillation is a prevalent condition linked to various health risks, and its management has evolved to focus on restoring and maintaining a normal heart rhythm. XYRA aims to revolutionize AF management by making it comparable to the treatment of other common cardiac conditions through effective drug titration guided by accessible monitoring tools.
