BioNovo, Inc. (BNVI) Announces Findings of Bezielle(TM) Anticancer Properties and Active Principles

2/7/2012 10:43:58 AM

EMERYVILLE, Calif., Feb. 7, 2012 /PRNewswire/ -- Bionovo, Inc. (NASDAQ: BNVI), a pharmaceutical company focused on the discovery and development of safe and effective treatments for women's health and cancer, today announced the publication of two studies that characterize the anticancer properties of its drug Bezielle, and that identify the active principles of the drug. The two papers are published in the Journal of the Public Library of Science One.


"There are various strategies to exploit the differences between normal cells and cancer cells that may allow the selective killing of tumor cells," said Dr. Emma Shtivelman, Director of Cancer Biology at Bionovo. "Bezielle takes advantage of a crucial inherent difference in how cancer cells produce energy for survival and rapid replication. Treatment with Bezielle inhibits cancer cells capacity to produce energy, and induces selective cancer cell death. The distinguishing feature of Bezielle is its ability to shut down both major cellular energy-producing pathways in cancer cells. The analysis of the active chemical components of Bezielle reveals important interactions of this drug with the metabolic pathways."

Bezielle has been evaluated in two early stage clinical trials in women with advanced and metastatic breast cancer, and has shown promising efficacy and excellent safety. Bionovo scientists have shown previously that Bezielle is highly selective toward cancer cells and has little cytotoxic activity towards normal cells. The new studies show that the selectivity of Bezielle is based on the inherent differences in the metabolic properties of cancer versus normal cells. Cell energy producing pathways are utilized and regulated differently in tumor cells that are frequently dependent on glycolysis for survival (known as the Warburg effect). They are efficiently targeted by Bezielle to induce energetic collapse and cell death. The normal cells are spared by Bezielle due to their reliance on mitochondrial energy production. In addition to the mechanistic analysis of Bezielle, the new studies provide a chemical analysis of the active compounds within Bezielle that are responsible for the anti-cancer activity of this drug.

"The two current publications continue to show the promise that Bezielle can provide to cancer patients. We hope to be able to initiate the Phase 2 clinical trials, lead by MD Anderson Cancer Center in Houston, Texas, in the near future," said Dr. Isaac Cohen, Chairman and CEO of Bionovo. "Cancer patients should have an oral, non-toxic drug with a unique mechanism of action as an option for cancer treatment."

Bezielle (BZL101)

Bezielle is an oral drug designed for the treatment of advanced breast cancer with a novel mechanism of action. Bezielle targets diseased cells while leaving normal cells healthy and intact. Normal cells depend primarily on the citric acid cycle (>85%) and very little on glycolysis (<7%) for energy production. Cancer cells depend largely on glycolysis (>85%) for energy production. Bezielle stops the production cycle of energy in cancer cells by inhibiting glycolysis. This leads to DNA damage and cell death in cancer cells while normal cells remain unharmed.

There are currently no effective therapeutic cures for advanced breast cancer and treatment is primarily aimed at palliation of symptoms as well as improving overall survival. Over 200,000 women in the United States are diagnosed with breast cancer each year and breast cancer is the second leading cause of cancer death in women. Although survival after breast cancer treatment is improving, there are still over 40,000 deaths per year due to the disease in the Unites States alone.
