"This agreement further strengthens our broad and deep oncology pipeline by adding a novel mechanism to treat solid tumors," said David Epstein, President and CEO of Novartis Oncology. "As a potentially first-in-class tumor vascular disrupting agent, AS1404 represents an opportunity to provide physicians and patients with an innovative new treatment option." Novartis reached this agreement following the presentation in November 2006 of positive Phase II results involving patients with non-small cell lung cancer that showed AS1404 extended median survival by five months when used in combination with a standard chemotherapy regimen of paclitaxel and carboplatin over chemotherapy alone. Recently reported results of a confirmatory Phase II trial in non-small cell lung cancer showed a response rate of 50% in AS1404 patients, while another 43% showed disease stabilization. AS1404, given as a 20-minute infusion immediately following chemotherapy, is the first compound in this new class of compounds called vascular disrupting agents (VDAs) to report positive data from a randomized Phase II clinical trial. These compounds selectively disrupt established blood vessels in solid tumors, which rely on a network to survive and grow. VDA compounds exert an effect different to angiogenesis inhibitors, which inhibit the formation of new tumor blood vessels. The need for new lung cancer treatments is urgent since it is one of the most common cancers worldwide with low survival rates. About 1.2 million deaths worldwide are linked to lung cancer each year. Non-small cell lung cancer represents about 80% of all lung cancer cases. The squamous form is one of three NSCLC types and represents 25% to 40% of cases. Initial data from other Phase II trials in ovarian and prostate cancers have shown increased response rates through the addition of AS1404 to standard chemotherapy. The potential benefits of this compound in these cancers, as well as other solid tumors, will be further explored during the development program. The addition of AS1404 to the Novartis pipeline brings to seven the number of compounds planned to enter late-stage development by the end of 2008. In addition to AS1404, other compounds include RAD001 (multiple tumors), SOM230 (Cushing's disease/refractory carcinoid tumors, acromegaly), LBH589 (chronic myeloid leukemia/cutaneous T-cell lymphoma), Tasigna (chronic myeloid leukemia), EPO906 (ovarian), and PKC 412 (acute myelogenous leukemia). AS1404 was discovered by Professors Bruce Baguley and William Denny and their teams at the Auckland Cancer Society Research Centre, University of Auckland, New Zealand. Antisoma acquired the rights to this compound from Cancer Research Ventures Limited (now Cancer Research Technology) in 2001. Financial terms of the agreement Novartis will gain the worldwide commercialization rights for AS1404 and will assume the management and costs of Phase III development. An upfront cash payment of USD 75 million will be made to Antisoma, which can receive additional payments of USD 380 million contingent upon the achievement of development milestones and approvals in four oncology indications worldwide and one non-oncology indication. Further potential milestones of up to USD 325 million are contingent on the performance of any future net sales. Antisoma will also receive sales royalties and has a co-commercialization option in the United States. An agreement has also been reached that provides Novartis an option to acquire a potential back-up compound to AS1404 that is currently in early-stage development. If this option is exercised, and if this back-up compound achieves development milestones and regulatory approval, Antisoma could receive up to an additional USD 110 million.
