Pegloticase BLA Update
Savient Provides Update on Pegloticase BLA
EAST BRUNSWICK, N.J., Feb. 12 /PRNewswire-FirstCall/ -- Savient Pharmaceuticals, Inc. today announced that the Company filed amendments to strengthen and clarify the data included in the previously submitted pegloticase Biologics License Application (BLA), which was granted priority review. The amendments focus on topics identified by the BLA Oversight Committee (the "Committee") of the Board of Directors as a result of its review of the BLA filing and also address review-related questions from the Food and Drug Administration (FDA).
Since its formation on November 19, 2008, the Committee, Chaired by Board Member Dr. Lee S. Simon, M.D., a former Director of the Analgesic, Anti-Inflammatory, Ophthalmologic Drug Products Division of the FDA and a Board Certified Rheumatologist with 25 years of clinical practice experience, has assumed oversight of all Company activities related to the FDA's BLA review process. The Committee has conducted a comprehensive review of the BLA filing with the assistance of external experts. In late January 2009, the Board of Directors also formally retained Dr. Simon as a consultant to assume day-to-day supervision of the BLA and Advisory Panel preparation.
"We believe the steps we have taken further clarify the favorable risk to benefit profile of pegloticase. Securing FDA approval remains our number one priority and we believe making these amendments is an important step toward achieving that goal. We look forward to continuing to work with the FDA as we move through the regulatory process. The Committee, our retained external experts, along with the management team, continue to believe in the relative benefit to risk profile of the safety and efficacy of this exciting product candidate when used in treating patients who suffer from treatment failure gout," said Paul Hamelin, President.
"I believe the recent amendments significantly enhance the overall application and better position the BLA to undergo a satisfactory FDA review. This is an exciting new therapy that, if approved, has the potential to have a meaningful impact on the patients who need it," said Dr. Simon. "Through our multi-faceted review, which included new analyses and further interpretation of data from a number of external experts, we have gained a greater understanding of the relative safety and efficacy of pegloticase and further clarification on the most appropriate uses for this product. Significantly, the data also confirms that a death imbalance of pegloticase does not exist."
In late November 2008, the Company engaged an experienced independent panel of clinical experts, headed by Dr. William B. White, Professor of Medicine, Calhoun Cardiology Center, School of Medicine, to perform a formal blinded and unblinded post-hoc adjudication of all cardiovascular events included in reports of Serious Adverse Events, Infusion Reactions and Severe Infusion Reactions from the Phase 3 pegloticase trials. The primary event evaluation was predicated on the Anti-Platelet Trialist Collaborative (APTC) assessment criteria. This is a standardized approach that the FDA has widely accepted as a method of evaluating cardiovascular risk. APTC cardiovascular events include deaths, nonfatal myocardial infarction or nonfatal stroke. Dr. White and his panel concluded that:
In addition to the work of Dr. White and his team, a separate external panel of experts performed an additional analysis by reviewing "all cause" mortality in the Phase 3 trials and Open Label Extension study. It is important to note that in the Phase 3 trials, there was a 2:2:1 randomization used, meaning that 4 times as many patients were on drug than placebo. However, in the Open Label Extension study virtually all patients were on drug with only 2 going on observation. The panel determined the following:
Upon review of these amendments, the FDA determined that the additional information contained in these submissions constituted a major amendment to the pegloticase BLA, which allowed the FDA under the Prescription Drug User Fee Act (PDUFA) regulations to extend the review period. In order to allow the agency time to consider these amendments, the FDA has notified the Company that the pegloticase BLA priority review PDUFA action date has been extended by three months to July 30, 2009. Given the extended action date, the FDA has also notified the Company that the Advisory Committee meeting previously scheduled for March 5, 2009 will be rescheduled. Savient will provide additional details regarding the rescheduling of the Advisory Committee meeting when a specific date and time have been determined.
"While we are eager to move the process forward as quickly as possible, the change in schedule does not impact our planning related to commercialization. The Company has always had a commercialization launch plan that parallels the FDA review process and that will be adjusted to meet the new PDUFA date," said Hamelin.
Krystexxa as a tradename was found to be acceptable by both the FDA and The European Medicines Agency (EMEA).
The Company will host a conference call and webcast today, Thursday, February 12, 2009, 2009 at 7:00 PM ET to discuss the status of the BLA and the amendments filed with the FDA. A question and answer period will follow the Company's prepared remarks. Both the live and archived web cast can be accessed from the Investor Relations page of Savient's website at http://www.savient.com.
A digital recording of the web cast will be available within two hours following the conclusion of the call and will be available for 14 days. To access the recording, use the Dial-In Number and the Conference ID listed below.
