About ProTriTAC™
Harpoon designed the ProTriTAC™ platform to expand the universe of addressable targets and indications for T cell engagers. IND enabling studies are underway for the first ProTriTAC™ clinical candidate, HPN601. ProTriTAC™ applies a prodrug concept to create a therapeutic T cell engager that remains inactive until it reaches the tumor. Upon entering a tumor, tumor-associated proteases cleave off the blocking domain of the ProTriTAC™, thereby enabling engagement of T cells to subsequently kill tumor cells. This activation process also diminishes the half-life of the resulting T cell engager. If active molecules leave the tumor tissue, they are rapidly eliminated from the body, further limiting potential side effects in normal tissues.
About Harpoon Therapeutics
Harpoon Therapeutics is a clinical-stage immunotherapy company developing a novel class of T cell engagers that harness the power of the body’s immune system to treat patients suffering from cancer and other diseases. T cell engagers are engineered proteins that direct a patient’s own T cells to kill target cells that express specific proteins, or antigens, carried by the target cells. Using its proprietary Tri-specific T cell Activating Construct (TriTAC®) platform, Harpoon is developing a pipeline of novel TriTACs initially focused on the treatment of solid tumors and hematologic malignancies. HPN424 targets PSMA and is in a Phase 1/2a trial for metastatic castration-resistant prostate cancer. HPN536 targets mesothelin and is in a Phase 1/2a trial for cancers expressing mesothelin including ovarian and pancreatic cancers. HPN217 targets BCMA and is in a Phase 1/2 trial for relapsed, refractory multiple myeloma. HPN328 targets DLL3 and Harpoon plans to initiate a Phase1/2 trial in the second half of 2020.
