2002 JAN 23 - (NewsRx.com & NewsRx.net) -- The Ludwig Institute for Cancer Research has initiated the first European Phase I trial for Therion Biologics' two-component vaccine targeting the tumor antigen NY-ESO-1.
In this study, the Ludwig Institute will evaluate the safety and potential activity of Therion's pox virus-based vaccine for enhancing the body's own immune response against cancer. This initial clinical study will include patients with a wide variety of ESO-expressing tumors, including breast and bladder cancer, melanoma and sarcoma.
"The Ludwig Institute's efforts are dedicated to turning leading-edge science into novel treatments for a variety of cancers," said Lloyd J. Old, chief executive officer at the Ludwig Institute. "As the first product from our joint research efforts with Therion enters the clinic, we recognize and look forward to other milestones in this collaboration."
The Phase I dose-ranging trial will assess the safety and immunologic profile of recombinant vaccinia-NY-ESO-1 (rV-NY-ESO-1) and recombinant fowlpox-NY-ESO-1 (rF-NY-ESO-1) in approximately 60 patients with NY-ESO-1 expressing tumors and undetectable NY-ESO-1 specific serum antibodies. The study is designed to evaluate the utility of the "prime-boost" approach to cancer therapeutics, which works by priming the immune system with one species of poxvirus and boosting with another to increase immune response over time. In addition, researchers ...
