How does the C2 CryoBalloon® work?

Cryoablation gets rid of unhealthy, diseased or damaged tissue by freezing it away. For this procedure, the doctor puts a balloon into the esophagus through an endoscope—a medical tube with a camera at its end that goes into the mouth and down towards the stomach—allowing the doctor to reach and see the esophagus.

Once inside the esophagus, the doctor will fill the balloon with air until it touches the sides of the esophagus. Next, the doctor sprays cold nitrous oxide (N2O) into the balloon to freeze the unhealthy cells. The nitrous oxide stays in the balloon, but the unhealthy cells just outside the balloon will freeze and die.

Are there current clinical trials for the C2 CryoBalloon®?

C2 Therapeutics is currently enrolling patients to participate in the Coldplay 3 Clinical Trial. Coldplay 3 is further evaluating the effectiveness of the C2 CryoBalloon® Focal Ablation System in patients with Barrett’s esophagus who have not yet received treatment. Previous studies have shown that treatment using the C2 CryoBalloon® has minimal complications and is well-tolerated by patients. 1-6
