About the Phase 1/2a Clinical Trial for HPN424
This Phase 1/2a trial is a multicenter, open-label study designed to evaluate the safety, tolerability, pharmacokinetics and activity of HPN424 in patients with mCRPC who are progressing. The trial is titled, “Study of HPN424 in Patients with Advanced Prostate Cancer.” For additional information about the trial, please visit www.clinicaltrials.gov using the identifier NCT03577028.
The initial phase of the trial is a dose escalation phase, with the goal of determining a recommended dose for the expansion phase of the trial. HPN424 is being administered to patients once weekly by intravenous infusion. The primary outcome measures are an assessment of safety and tolerability, pharmacokinetics, and determination of a dose for the expansion phase of the trial. Secondary endpoints include overall response rate, progression free and overall survival, and duration of response. The expansion portion of the trial will further evaluate the safety and activity of HPN424 in patients with mCRPC.
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, initially focused on ovarian and pancreatic cancers. HPN217 targets BCMA and is in a Phase 1/2 trial for relapsed, refractory multiple myeloma. HPN328 targets DLL3 and is in a Phase 1/2 trial for small cell lung cancer and other DLL3-associated tumors. Harpoon has also developed a proprietary ProTriTAC™ platform, which applies a prodrug concept to its TriTAC platform to create a therapeutic T cell engager that remains inactive until it reaches the tumor.
