A Third Cancer Drug Just Entered the Clinic at an Under-$20-Million Company
GT Biopharma announced its third cancer drug, GTB-5550, entered Phase 1 clinical trials on May 14, 2026, marking the company's first expansion into solid tumors. Despite having three drugs in human trials—unusual for a micro-cap—the company trades at a significant valuation discount compared to peers, with only ~$9 million in cash and a runway into late 2026. The gap between its scientific promise and market valuation presents both opportunity and substantial risk, with near-term catalysts including clinical data updates and financing announcements expected in H2 2026.
