"We are gratified that we have found an excellent partner for the development of XL119," said George A. Scangos, Ph.D., president and chief executive officer of Exelixis. "Helsinn is a high-quality company with experience in cancer drug development, as demonstrated by their successful development and licensing of Aloxi® to MGI Pharma. By combining our resources with those of an excellent European partner, we hope to make XL119 available to patients in need around the world. This agreement will free up substantial financial and product development resources, allowing Exelixis to focus on the Phase I and II trials for our internally developed pipeline. At the same time, we have structured this deal with rights to reacquire the commercial rights to XL119 for North America, which is our primary market. I believe that this is an excellent transaction and represents a win for both companies," said Dr. Scangos.
"Exelixis has a very strong scientific foundation and we are pleased to be in a partnership with such a company," said Enrico Braglia, Managing Director of Helsinn. "Through the development of XL119, we aim to create a new standard of care for patients with biliary tract cancers, a rare and aggressive form of cancer with a high medical need and very limited survival. While some existing therapies have been used off-label to treat this type of tumor, there is currently no drug therapy that has been approved by regulatory authorities for this indication. We believe that XL119 will offer a meaningful therapeutic benefit over currently used therapies and will become the therapy of reference for biliary tract cancer patients worldwide."
XL119 is currently in a multi-national Phase III clinical trial at approximately 50 centers in North America and Europe. The primary endpoint of the 600-patient trial is increased survival of patients with bile duct tumors treated with XL119 compared with the chemotherapy agents 5-fluorouracil (FU) and leucovorin. The trial is currently recruiting and enrolling patients as anticipated and is on track to be completed as planned. XL119 was granted the Orphan Drug designation in the USA on March 1, 2004.
