Mary Crowley Advances New Targeted Investigational Therapy For Ewing Sarcoma

Targeted Clinical Trial for Ewing Sarcoma Now Open

DALLAS, December 5, 2016– Mary Crowley Cancer Research has opened a new Phase I clinical trial for advanced Type I Ewing sarcoma, a rare bone cancer affecting children, adolescents, and young adults. The first patient has received the investigational therapy and is currently undergoing a response evaluation. Patients with rapidly recurrent Ewing sarcoma have less than a 10% chance of surviving more than five years, and yet no new treatments have been developed in decades. The Principal Investigator for the clinical trial is Dr. Maurizio Ghisoli located at Medical City Hospital Dallas.

The investigational agent, pbi-shRNA EWS/FLI1 Lipoplex, is the only agent currently under investigation in the U.S. that targets the EWS/FLI1 translocation, or Driver Gene, specific to Ewing sarcoma. Developed by Dallas biotech company, Strike Bio, Inc.; this agent utilizes a platform RNA interference technology that if proven, could be applied to multiple other cancers with elusive targets. Mary Crowley is already underway to expand this technology for more sarcoma subtypes.

Mary Crowley has dedicated research efforts to impact Ewing’s, offering patients access to three clinical trials for patients with the rare disease. In 2009, Mary Crowley began exploring adult RNAi anti-cancer technology and its potential application for children fighting Ewing’s. The resulting immunotherapy is now in Phase II testing
at multiple sites across the U.S. including Mary Crowley.

“Since 2012, we have enrolled more than 24 children with advanced Ewing sarcoma, on innovative molecular and immunotherapy trials. I am excited to offer these patients access to cutting edge clinical trials,” said Maurizio, Ghisoli, M.D.

Laura Rutledge of the Rutledge foundation said, “Until our own daughter was diagnosed with Ewing sarcoma at the age of 15, I had no idea of the lack of funding for new cancer therapies, especially for rare cancers, like our daughter’s. Because of the grass-roots support of families who have been affected by cancer and donors who believe in our mission, the Rutledge Foundation has been able to lead the way in supporting Mary Crowley’s development of targeted and immune-based cancer therapies.”

Despite a serious need for new treatment approaches, new cancer therapies for children generally lag years behind those for adults due to the smaller pediatric cancer population and fewer funding sources. Private philanthropy has proven crucial to development of novel approaches in pediatric cancers. Families impacted by Ewing sarcoma have united with private foundations and Mary Crowley to pursue innovative treatments.
