New chemo drug gentler on fertility, tougher on cancer
Date:3/22/2013

n humans, but O'Halloran thinks the arsenic trioxide nanobins can be used against breast cancer and other solid tumors. In his previously published preclinical research, nanobins were effective in reducing tumor growth in triple-negative breast cancer, which often doesn't respond well to traditional chemotherapy and has a poor survival rate.

Quick Test For Fertility Toxicity

Woodruff was able to show early effects of the drug on fertility by using an in vitro follicle culture and a quick, simple new test she developed. She compared the fertotoxicity of the nanobin and free drug and found the nanobin was much less toxic to female fertility than the free drug in the experimental model.

"The system can be adapted very easily for any cancer drug under development to get an early peek under the tent,"said Woodruff, also the Thomas J. Watkins Memorial Professor of Obstetrics and Gynecology at Feinberg. "As this new drug goes forward in development, we can say this is a good drug for young female cancer patients who are concerned about fertility."

The information gained from the toxicity test will help inform the treatment decisions of oncologists and their young female cancer patients to improve their chances of creating a future family.

"They may prescribe less toxic drug regimens or refer them to specialists in fertility preservation," Woodruff said.
