SUPLEXA, a personalized cancer treatment, trains patients' immune cells to fight cancer. Developed by Alloplex Biotherapeutics, it involves a simple blood draw, ex vivo cell training, and reinfusion. The first-in-human trial showed no serious adverse events and significant clinical benefits in advanced colorectal and renal cell carcinoma patients. The FDA has encouraged Alloplex to proceed with Phase 2 trials, combining SUPLEXA with immune checkpoint inhibitors.
