Bristol-Myers Squibb, Bavarian Nordic ink agreement for PROSTVAC
Bristol-Myers Squibb has signed an exclusive option to license and commercialize PROSTVAC, Bavarian Nordic's investigational phase III prostate-specific antigen (PSA)-targeting cancer immunotherapy in development for the treatment of asymptomatic or minimally symptomatic metastatic castration-resistant prostate cancer (mCRPC).
Bavarian Nordic will receive an upfront payment of $60 million. Bristol-Myers Squibb can exercise the option in its sole discretion within a designated time after data is available from the ongoing phase III trial. Bavarian Nordic would be entitled to a payment of $80 million upon exercise of the option plus additional incremental payments starting at $50 million, but with a potential to exceed $230 million should the median overall survival benefit of PROSTVAC exceed the efficacy seen in phase II results. Furthermore, Bavarian Nordic could receive regulatory milestone payments of $110 million, up to $495 million in sales milestones as well as tiered double-digit royalties on future sales of PROSTVAC. The parties also have agreed to enter into a supply contract, under which Bavarian Nordic will undertake the future commercial manufacturing of PROSTVAC.
An investigator sponsored phase II study currently is in the planning stages to investigate the combination of Bristol-Myers Squibb's YERVOY (ipilimumab) and PROSTVAC. The companies also have entered into an agreement by which they may conduct one or more exploratory combination studies of PROSTVAC and agents from Bristol-Myers Squibb's immuno-oncology portfolio.
"While additional treatment options have become available, metastatic castration-resistant prostate cancer remains largely incurable," said Michael Giordano, head of development, oncology, Bristol-Myers Squibb. "Our agreement with Bavarian Nordic reflects our commitment to following the emerging science in immuno-oncology and supports our strategy to transform the treatment of cancer across multiple tumor types, lines of therapy and stages of disease."
Bristol-Myers Squibb has an ongoing phase III program for YERVOY in prostate cancer, and scientific rationale exists to evaluate PROSTVAC in combination with YERVOY, and other agents from Bristol-Myers Squibb's immuno-oncology portfolio.
