HPN-328 is under clinical development by Harpoon Therapeutics and currently in Phase II for Pancreatic Cancer. According to GlobalData, Phase II drugs for Pancreatic Cancer have a 26% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how HPN-328’s drug-specific PTSR and Likelihood of Approval (LoA) scores compare to the indication benchmarks. Buy the report here.
GlobalData tracks drug-specific phase transition and likelihood of approval scores, in addition to indication benchmarks based off 18 years of historical drug development data. Attributes of the drug, company and its clinical trials play a fundamental role in drug-specific PTSR and likelihood of approval.
HPN-328 overview
HPN-328 is under development for the treatment of small-cell lung cancer, neuroendocrine prostate cancer and other neuroendocrine neoplasm like colorectal cancer, pancreatic cancer, thymic carcinoma, bladder cancer. The drug candidate is a single polypeptide comprising a single-chain variable fragment (scFv) targeting cancer surface antigen DLL3 and two single-domain antibodies that binds to the CD3 epsilon subunit of the TCR and to human serum albumin. It is a tri-specific antibody and T cell engager. It is developed based on tri-specific T-cell activating construct (TriTAC) technology. It is administered through intravenous route.
Harpoon Therapeutics overview
Harpoon Therapeutics (Harpoon) is a clinical-stage immuno-oncology 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. The company’s pipeline products include Hpn424, a T cell-engaging bispecific antibody used for the treatment of prostate cancer; HPN536 against ovarian cancer; HPN217 targeting Multiple Myeloma; HPN328 indicated for small cell lung cancer; and HPN601, is a protease-activated EpCAM targeting T cell engager for the treatment of solid tumors. It utilizes Tri-specific T cell activating construct (TriTAC) platform, for developing a pipeline of novel T cell engagers designed for targeted penetration and destruction of solid tumors and hematologic malignancies. Harpoon is headquartered in South San Francisco, California, the US.

GlobalData, the leading provider of industry intelligence, provided the underlying data, research, and analysis used to produce this article.
GlobalData’s Likelihood of Approval analytics tool dynamically assesses and predicts how likely a drug will move to the next stage in its clinical pathway (PTSR), as well as how likely the drug will be approved (LoA). This is based on a proprietary algorithm built from the drugs’ sales forecast, regulatory milestones, cost forecasts, WACC rate and other proprietary data sources found on GlobalData’s Pharmaceutical Intelligence Center.
