HB-300 is under clinical development by Hookipa Pharma and currently in Phase II for Metastatic Castration-Resistant Prostate Cancer (mCRPC). According to GlobalData, Phase II drugs for Metastatic Castration-Resistant Prostate Cancer (mCRPC) have a 34% phase transition success rate (PTSR) indication benchmark for progressing into Phase III. GlobalData’s report assesses how HB-300’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.

HB-300 overview

HB-300 is under development for the treatment of metastatic, hormone-resistant prostate cancer. The vaccine candidate constitutes recombinant viral vector expressing self-antigen. It is administered through intravenous route. The therapeutic candidate development is based on the TheraT technology platform. It combines the two arena virus vector technologies and boosts the immune response against the tumor-associated antigen. The drug candidate acts by targeting prostatic acid phosphatase (PAPA), prostate-specific antigen (PSA) and prostate-specific membrane antigen (PSMA).

Hookipa Pharma overview

Hookipa Pharma (Hookipa) is a clinical-stage biopharmaceutical company that develops novel class of immunotherapeutics against infectious diseases and cancers. Its pipeline products include HB-101, a prophylactic cytomegalovirus vaccine candidate; HB-202 and HB-201, immuno-oncology product candidates for the treatment of human papillomavirus-positive cancers; and HB-301, targeting prostate cancer. Hookipa’s proprietary arenavirus-based technologies, VaxWave, a replication-deficient viral vector, and TheraT, a replication-attenuated viral vector, are designed to induce antigen specific cytotoxic T cells and pathogen-neutralizing antibodies for prophylactic and therapeutic purposes activating body’s immune response. The company collaborates with Gilead Sciences Inc for the development of immunotherapies to treat HIV and Hepatitis B. It operates a research and preclinical development center in Vienna, Austria. Hookipa is headquartered in New York City, New York, 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.
