Bionovo Develops a High Throughput LC-MS/MS Tandem Quantification of Multiple Bioactive Compounds
EMERYVILLE, Calif., May 25 /PRNewswire-FirstCall/ -- Bionovo, Inc. (Nasdaq: BNVI) today announced that it has developed a novel analytical 2-dimensional liquid chromatography mass spectrometry-based (LC/LC-MS/MS) multiplexing platform that allows for the rapid, specific, sensitive automated quantification of the active pharmaceutical compounds of Menerba, the company's most advanced drug candidate. The novel quantification was initially developed for Menerba, which is botanically derived, and has shown positive Phase 2 results for the treatment of hot flashes associated with menopause. The assay was validated in multiple matrices ranging from Menerba extracts for production quality control to plasma in pharmacokinetic and safety trials.
"The development of botanical drugs is far more challenging than a single molecule drug, since these are complex mixtures containing a number of bioactive compounds," said Dr. Yan Ling Zhang, Bionovo's Director of Analytical Chemistry. "Our assay is capable of sensitively and specifically quantifying 10 active Menerba compounds in one short analytical run, and allows us to prove the exquisite precision and consistency of our manufacturing process. This is a tremendous advantage over conventional assays that usually measure a single compound."
"The availability of this robust high-throughput assay is a key to the development of Menerba," said Dr. Isaac Cohen, Bionovo's Chairman and Chief Executive Officer. "Having the tool to quantify multiple actives at femtomolar range solves important questions for manufacturing controls, dose assessment and safety measures. This analytical platform technology is critical to the study of Menerba."
The poster outlining the new technology is entitled, "Scientific Quantification of 10 Bioactive Polyphenolic Compounds in Menerba by a High Throughput LC-MS/MS Method," and will be presented today, Tuesday, May 25, 2010, at the American Society for Mass Spectrometry's 58th ASMS Conference in Salt Lake City.
Menerba is an oral botanical drug candidate designed for the safe, effective treatment of vasomotor symptoms (hot flashes) associated with menopause. Menerba is an estrogen receptor beta (ER-b) selective drug, developed as an alternative to the products currently on the market, which have been shown to increase the risk for breast and uterine cancers. It has been shown that the increased risk of breast and uterine cancers is associated with activation of estrogen receptor alpha and that activation of estrogen receptor beta blocks the growth promoting effects on breast cancer cells. Bionovo recognized the opportunity to commercialize a product that would be as effective as hormone therapy, without the health risks. Menerba has completed a Phase 2 trial with positive results for efficacy and has been evaluated by an independent Data and Safety Monitoring Board and passed through a standard two-round examination for safety.
