GT Biopharma Announces Potential New Indication for GTB-5550, a B7-H3-Targeted Natural Killer (NK) Cell Engager, for Multiple Myeloma
GT Biopharma announced that the FDA cleared a new investigational new drug (IND) application for GTB-5550, a B7-H3-targeted natural killer (NK) cell engager, for use in multiple myeloma under an investigator sponsored trial protocol. The company also noted its Phase 1 basket trial in solid tumor patients is actively enrolling, and its unaudited cash balance of about $11 million is expected to fund operations into Q3 2027.
Why it matters — This expands GTB-5550's potential into a new indication, multiple myeloma, adding to the GTBP pipeline and extending its cash runway into Q3 2027.
