Bavarian Nordic Receives Special Protocol Assessment Agreement From the FDA for Phase 3 Trial of PROSTVAC(R)KVISTGAARD, Denmark, Dec. 8, 2010 -- (Healthcare Sales & Marketing Network) -- Bavarian Nordic A/S (Copenhagen:BAVA ) announced today that the company has received a letter of concurrence from the U.S. Food and Drug Administration (FDA) on a Special Protocol Assessment (SPA) for a Phase 3 study required for product registration for its product candidate, PROSTVAC(R), for the treatment of patients with asymptomatic or minimally symptomatic metastatic castration-resistant prostate cancer. This agreement reached with the FDA on this SPA means that the Phase 3 study can proceed as designed and, if successful, could form the primary clinical basis of product approval under a Biologics Licence Application.
"We are very pleased with the agreement on the Special Protocol Assessment with FDA. It not only represents a significant milestone in the development of PROSTVAC(R), but also marks the key step in the regulatory process before the initiation of the Phase 3 study, anticipated to start enrolment late summer 2011, upon release of clinical trial material. We believe that PROSTVAC(R) will provide important benefits in survival and quality of life, compared to existing treatments in advanced prostate cancer," commented Anders Hedegaard, President & CEO of Bavarian Nordic.
A conference call is held today, Wednesday, December 8 at 4 p. m. CET with the participation of Anders Hedegaard, President and CEO, and Reiner Laus, Division President Cancer Vaccines. Dial-in numbers for the conference call are: Denmark: +45 3271 4611, UK: +44 (0)20 7162 0077, US: +1 334 323 6203.
About the Phase 3 program
The Phase 3 program will include a single global, strongly powered, randomized, double-blind, placebo-controlled study that is expected to enrol about 1,200 patients in three study arms. Patients in the two active study arms will receive either PROSTVAC(R) alone or PROSTVAC with adjuvant doses of GM-CSF (which was included in Phase 2). Patients who have metastatic disease and have failed hormone therapy, but who have not yet received other treatment options such as chemotherapy, will be eligible to enrol in the study. The primary endpoint is overall survival (OS). For the study outcome to be positive, either one or both of the treatment arms must be superior to placebo. The phase 3 trial is sized so that each comparison requires 534 deaths with sensitivity for estimated death hazard ratios of 0.82 or less.
About Special Protocol Assessments
The Special Protocol Assessment (SPA) process is a procedure by which the FDA provides official evaluation and written guidance on the design and size of proposed protocols that are intended to form the basis for a Biologics License Application or New Drug Application (BLA, NDA). Final marketing approval depends on the results of efficacy, the adverse event profile and an evaluation of the benefit/risk of treatment demonstrated in the Phase 3 trial.
PROSTVAC(R) is an "off-the-shelf" therapeutic vaccine moving into late stage clinical development that has the potential to extend the lives of people with advanced prostate cancer. Administered subcutaneously, it induces a specific, targeted immune response that attacks prostate cancer cells. Conventional chemotherapy currently used to treat prostate cancer has shown limited improvement in OS and is often associated with serious side effects. In contrast, PROSTVAC(R) has the potential to extend survival with minimal toxicity.
In a large, prospective randomized, double-blind, placebo-controlled Phase 2 study of 125 patients with metastatic prostate cancer, patients in the PROSTVAC(R) group had a significantly longer median overall survival by 8.5 months compared to the control group (p=0.006). The hazard ratio estimate for overall survival from the study is 0.56 (95% CI 0.37-0.85).
PROSTVAC(R) is being developed in collaboration with the National Cancer Institute under a Cooperative Research and Development Agreement with Bavarian Nordic's U.S.-based subsidiary, BN ImmunoTherapeutics. In 13 completed clinical trials to date, PROSTVAC(R) and related PSA containing poxviral vaccines have been investigated in more than 570 patients.
In April 2010, PROSTVAC(R) was granted Fast Track designation by the FDA for the treatment of men with asymptomatic or minimally symptomatic metastatic castration-resistant prostate cancer (mCRPC).
