A former ExThera Medical executive has admitted to covering up the deaths of two cancer patients who were treated with a blood-filtering device from the FDA and the department. The Seraph 100 Microbind Affinity Blood Filter device is adulterated by the FDA under section 501(f)(1)(B) of the Act. The company used the device in the Oscar Study to remove circulating tumor cells in patients with metastatic pancreatic ductal adenocarcinoma under IDE G230144. In December 2024, Dr. Chawla said in the podcast that the device was used in patients with long COVID under compassionate use, where brain fog and fatigue improved. He also claimed that the device has been used in more than 2,500 patients, is as safe as dialysis and suitable for outpatients with cancer, long COVID or chronic viremia. The FDA has alerted ExThera to ensure that distributors outside the US do not make false claims about approval of the device.[1]
