Bavarian Nordic Provides Update on Anticipated Timing of PROSPECT Study

COPENHAGEN, Denmark, June 16, 2017 - Bavarian Nordic A/S (OMX: BAVA, OTC: BVNRY) today provided updated guidance for the current anticipated timing of interim and final results from its ongoing PROSPECT study, a placebo-controlled Phase 3 study designed to investigate the efficacy of PROSTVAC to prolong the survival of men with metastatic castration-resistant prostate cancer (mCRPC).

As previously communicated, Bavarian Nordic still expects the PROSPECT study to read out final data in the second half of 2017. The company now further updates this timeline to indicate the final data is expected in the fourth quarter of the year. Prior to the final data analysis, however, a third interim analysis is planned. The results of the third interim analysis will be reviewed by an independent Data Monitoring Committee (DMC) and the DMC now plans to convene for this analysis in September 2017. The Company will provide an update following this interim analysis.

About the PROSPECT study
The PROSPECT study is a global randomized, double-blind, placebo-controlled study in patients with asymptomatic or minimally symptomatic mCRPC. The trial is being conducted under a Special Protocol Assessment agreement with the FDA. The primary objective of the study is to determine whether the overall survival of patients receiving PROSTVAC (with or without the addition of granulocyte macrophage colony-stimulating factor; GM-CSF), is superior to that of patients receiving placebo. The final analysis of the study will occur at 534 events (deaths) in each comparison of the two treatment arms versus placebo. Three pre-specified interim analyses of data have been integrated into the statistical plan to evaluate whether the trial should continue as planned, or potentially be stopped early for efficacy or futility. Two of these interim analyses have already occurred, with the conclusion that the study continue without modification. 

The study completed recruitment in January of 2015 with a final enrolment of 1,297 men.  Based on the dosing schedule of PROSTVAC, all men would have completed their course of therapy no later than June 2015.

About PROSTVAC
PROSTVAC (rilimogene galvacirepvec/rilimogene glafolivec) is a prostate specific antigen (PSA)-targeted immunotherapy candidate designed to enhance or stimulate the body's immune response, specifically T cells that will home to and kill prostate cancer cells, altering the course of the disease and improving overall survival (OS) of patients with prostate cancer. A robust data package has been established that includes 19 ongoing or completed clinical studies, comprising more than 2,000 patients of which more than 1,100 patients have been actively treated with PROSTVAC, which has been generally well-tolerated. A randomized, placebo-controlled Phase 2 trial demonstrated the potential of PROSTVAC to extend the median overall survival by 9.9 months in patients with advanced prostate cancer.

PROSTVAC is being developed in collaboration with the National Cancer Institute under a Cooperative Research and Development Agreement.
