ducted at four sites in the U.S., including the University of Colorado Cancer Center (Aurora, CO), The University of Texas M.D. Anderson Cancer Center (Houston, TX), Cancer Institute of New Jersey (New Brunswick, NJ) and The Institute for Drug Development (San Antonio, TX). R1507 has also been investigated in 26 patients on a three week schedule in the Phase I study. This treatment schedule was also generally well tolerated with a side effect profile similar to the weekly schedule.

"This drug attacks the IGF pathway and may provide a new class of drugs to treat a variety of cancers, including breast, prostate, colon, melanoma, myeloma and a variety of sarcomas, which could greatly add to the way that we currently treat these patients," says Stephen Leong, M.D., assistant professor of Medical Oncology at the University of Colorado Cancer Center and lead author of the abstract.

Razelle Kurzrock, MD, investigator at the M.D. Anderson Cancer Center and the senior author of the abstract, noted that some of the responses were very impressive. For instance, one 28 year-old Ewing's sarcoma patient with large tumors unresponsive to many other treatments showed dramatic tumor shrinkage within six weeks, without side effects. "This is one of the best responses I've seen in over 20 years of oncology experience," stated Dr. Kurzrock.

Based on these initial results with R1507, Roche plans to conduct additional trials and work with a global consortium of sarcoma experts, including the Sarcoma Alliance for Research through Collaboration (SARC). "We are very excited about our collaboration with SARC, which represents a new approach to sarcoma clinical trials, and we look forward to combining our expertise with that our colleagues at SARC to expedite new sarcoma treatments," added Dhingra.

"We are excited to be partnering with Roche on the development of a new treatment against an important target, which could result in a potential breakthrough treatment for s
