FDA clears IND application for Ph 1 study of GTB-5550 TriKE for Solid Tumors Expressing B7-H3
“FDA clearance of our third TriKE® IND, GTB-5550, represents a defining moment for GT Biopharma as we bring another NK cell engager into the clinic”, said Michael Breen, Executive Chairman and Chief Executive Officer of GT Biopharma. “We expect to commence enrollment of the Phase 1 basket trial in mid-2026. While the phase I trial is open to patients with common solid tumors that express B7-H3, in the dose-escalation component we will prioritize enrollment for advanced prostate, ovarian, and pancreatic cancer patients who have failed standard therapies. Based on the encouraging trends we have seen from our ongoing Phase 1 trial with GTB-3650 in AML patients, we are even more enthusiastic about the potential benefits of GTB-5550 treatment in patients with solid tumors known to express B7-H3.”
