GT Biopharma, Inc.

GT Biopharma, Inc. was founded in 1997 and is headquartered in San Francisco, California. The company operates as a clinical-stage biotechnology firm, with CEO Anthony Cataldo leading from 2011 onward. Its wealth origin is not publicly disclosed. The firm's strategy centers on immuno-oncology, specifically NK cell-directed therapies. Their lead candidate targets CD16 activation to treat hematologic malignancies. GT Biopharma partners with the National Cancer Institute and other academic institutions for research (per SEC filings, 2023). GT Biopharma has not disclosed team size or AUM. The firm maintains no known adjacent vehicles. As of 2025, it continues to advance its pipeline through Phase 1/2 trials, with no revenue from approved products. The structural differentiator is its public-company status: GT Biopharma trades on the NASDAQ under ticker GTBP. This allows capital access via equity markets, distinct from private biotechs.
