Publication Highlights Major Potential Safety Advantages of Company's Lead Drug Candidate
EMERYVILLE, Calif., Dec 06, 2006 /PRNewswire-FirstCall via COMTEX/ -- Bionovo, Inc.'s ( BNVI ) paper describing the mechanism of action of MF101, the company's lead drug candidate for menopausal symptoms, has been published in Endocrinology, a journal published by The Endocrine Society. The paper titled "Selective activation of estrogen receptor beta transcriptional pathways by an herbal extract" details how MF101 is selective to the estrogen receptor beta (ER-b) and does not affect estrogen receptor alpha (ER-a). This is a significant milestone toward the development of safe and effective drugs for menopause since it has been shown that the increased risk of breast and uterine cancers is associated with ER-a activation and that ER-b blocks the growth promoting effects on breast cancer cells.
"The results of our studies have demonstrated that MF101's ER-b selective estrogens may be a safer alternative to alleviate symptoms of menopause than traditional estrogens," said Dale Leitman, M.D., Ph.D., Center for Reproductive Endocrinology, University of California, San Francisco and member of Bionovo's Scientific Advisory Board. "Our findings suggest that targeting the ER-b will not only preserve the anti-inflammatory action potentially responsible for combating hot flashes and osteoporosis but will also be devoid of the proliferative effects of estrogens used in hormone therapy that are responsible for causing cancer."
The current study demonstrated that ER-b selectivity by MF101 is not due to differential binding since MF101 binds equally to ER-a and ER-b, but instead, showed that MF101 produces a different conformation in ER-a from ER-b resulting in selective ER-b regulation. The study also demonstrated that MF101 did not activate the genes that mediate the increased risk of breast and uterine cancers caused by estrogens. This effect of MF101 was confirmed in a mouse breast cancer model.
"Today, people are more familiar with the issues associated with menopause than ever before, because the life expectancy of women has risen dramatically over the past several decades. The results of the Women's Health Initiative (WHI) trial have shown that traditional hormone therapy increases the risks for breast cancer, strokes, heart disease, dementia and blood clots and the data have left women with few safe options to alleviate their symptoms," said Mary Tagliaferri, M.D., co-founder and Chief Medical Officer, Bionovo. "The mechanism of action of MF101 suggests that it may provide women with relief from menopausal symptoms, such as hot flashes and night sweats, while not compromising their overall health. Prior to the results of the WHI, the hormone therapy market was approximately $6.5 billion. With the baby boomers now transitioning into menopause, we expect the market size of those women looking for a safe and effective solution to grow dramatically."
MF101 is currently in Phase 2 clinical testing at six clinical sites throughout the country. The Principal Investigator for the Phase 2 trial is Dr. Deborah Grady, University of California, San Francisco. The Company anticipates that results from the Phase 2 trial will be available in the second quarter of 2007.
