FDA Gives Permission to Use Very Sensitive Molecular Evidence of Cancer in BiovaxID Pivotal Phase 3 Clinical TrialBiovest Intends to Use Blood Test to File Application for Accelerated Approval
Analysis of Combined Clinical Plus Molecular Remission May Provide Early Demonstration of Efficacy for Novel Anti-Cancer Immunotherapy
WORCESTER, Mass.--(HSMN NewsFeed)--May 16, 2006--Biovest International, Inc. (OTCBB: BVTI ) has been notified by the United States Food and Drug Administration (FDA) that its proposal to utilize molecular remissions data as a new secondary endpoint in its ongoing clinical trial is acceptable to the agency. Biovest is conducting a pivotal Phase 3 trial evaluating BiovaxID(TM), the Company's personalized, targeted anti-cancer immunotherapy for treatment of follicular non-Hodgkin's lymphoma at over 20 major medical centers throughout the U.S. Biovest previously reported positive Phase 2 results for BiovaxID - more than 9 years after treatment 95% of BiovaxID treated patients are still alive. Approximately 70 % of evaluable patients showed no evidence of tumor cells when measured using highly precise molecular remissions data. Biovest had asked the FDA to review a request to collect data on molecular remissions, combined with physical examination and CT scan evidence of gross tumor remission as part of a revised secondary endpoint for its ongoing trial. Biovest had also proposed that the data be analyzed as part of annual Data Safety Monitoring Board (DSMB) reviews of its clinical trial. Biovest believes that recent advancements in molecular analysis, which enable the detection of small numbers of cancer cells in the blood, can be used to provide a sensitive and early indication of tumor remission. Biovest believes this could lead to a faster demonstration of statistically significant benefit of BiovaxID and to earlier FDA approval of BiovaxID. If the data demonstrate a statistically significant benefit of BiovaxID on combined molecular and clinical tumor-free survival, Biovest will request that the FDA grant approval to BiovaxID. Such approval would allow the Company to commence commercial marketing of BiovaxID while it completes its ongoing Phase 3 study.
Non-Hodgkin's lymphoma (NHL) is a cancer of the lymphatic system involving a type of white blood cell called a lymphocyte. Because of a characteristic chromosomal abnormality in the cancer cells in NHL, as few as 1 malignant lymphocyte in 100,000 normal cells can be detected in the blood using a sensitive molecular test method known as polymerase chain reaction (PCR). The absence of detectable cancer cells in the blood, based on this sensitive test, is referred to as molecular remission. The preponderance of published clinical studies using a variety of therapeutic regimens has demonstrated a strong relationship between molecular remission and the length of tumor-free survival.
Dr. Steve Arikian, Biovest Chairman and CEO commented:
"The FDA's encouragement to move forward with this revised end point and data analysis could allow Biovest to shorten the time it takes to show a difference between treatment and control arms in the ongoing pivotal Phase 3 study. This may allow us to apply for approval of BiovaxID significantly earlier than might otherwise be possible."
Dr. Arikian continued:
"In its Phase 2 trial, BiovaxID successfully induced molecular remission in approximately 70% of the evaluable treated patients - meaning that cancer cells could not be detected in the patient's blood using the most sensitive molecular screening techniques available. Using this same approach in our Phase 3 trial may put us in a position to have an approved indication for BiovaxID substantially earlier than would be possible using traditional clinical endpoints. This means that a potentially life-saving cancer therapy could become available to patients much sooner than would otherwise be the case."
