San Francisco – Tokai Pharmaceuticals is a case study in how not to do drug development.

A company, founded in 2004, with a novel prostate cancer drug has taken 10 years to make it to phase II drug development while competitors such as Medivation and Johnson & Johnson have brought similar new drugs to market in multiple prostate cancer indications.

armor-logoAt ASCO GU this week (Abstract 71), Tokai reported part 1 of their phase 2 ARMOR2 trial with reformulated galeterone (TOK-001) in men with prostate cancer at various stages of the disease in a poster.  Part 2 of the study will enrol 136 patients with a once daily dose of 2550 mg.

Subscribers to Premium Content can read below an analysis of some of the challenges that Tokai Pharmaceuticals faces, which raise the question of whether galeterone will in fact make it to market?

Galeterone (Tokai Pharmaceuticals) is a new prostate cancer drug in development that has an interesting triple mechanism of action in that like abiraterone (Zytiga) it acts as a CYP17 lyase inhibitor, but it also acts as an androgen receptor (AR) inhibitor and is an AR degrading drug that decreases AR levels.

How effective it is compared to AR antagonists on the market such as enzalutamide (Medivation) or second-generation AR antagonists in development such as ARN-509 (Aragon Pharmaceuticals) or ODM-201 (Orion Pharma) is one of the many unanswered questions with this drug.
