About ADGM
Adagio Medical Holdings, Inc. is a medical device company. The Company is focused on developing and commercializing products for the treatment of cardiac arrhythmias with catheter-based ultra-low temperature ablation (ULTA) technology, formerly known as ultra-low temperature cryoablation (ULTC) technology. Its initial focus is on the treatment of ventricular tachycardia (VT), which is a rapid, abnormal heart rhythm, or arrhythmia, that originates in the heart’s lower chambers, or ventricles, potentially leading to impaired blood flow and, if sustained, it can be fatal. Its ULTA products are purpose-built to treat patients with VT and are designed to address the unique anatomy of the ventricle and the specific needs of the VT patient. Its catheters and consoles are designed to create titratable, large, durable, deep lesions within the ventricle through a stable, endocardial or inside the heart approach with no required irrigation.

Adagio Submits PMA Application for vCLAS System
- Clinical Trial Success: The FULCRUM-VT trial enrolled 209 patients across 20 leading centers, achieving a 97.4% acute clinical success rate, demonstrating the system's effectiveness in treating drug-refractory ventricular tachycardia, which is expected to significantly enhance treatment options for patients.
- Significant Market Potential: The PMA application for the vCLAS system marks the first-ever submission of a purpose-built device in the ventricular ablation market, projected to reach $5.8 billion, positioning Adagio to capture market share and address unmet medical needs with this innovative technology.
- Safety and Efficacy: Trial results indicated that 84.3% of patients experienced freedom from ICD shocks within six months, with only 2.4% major adverse events, highlighting the vCLAS system's superior safety and efficacy, which could redefine treatment standards in cardiology.
- Strategic Implications: Adagio's CEO emphasized that this technology is not just a new approach to VT ablation but a fundamentally better solution aimed at providing uncompromised treatment for all eligible VT patients, signaling the company's leadership position in cardiac care.
