Threshold Pharmaceuticals, Inc

today announced that a global agreement was signed with Merck KGaA, Darmstadt, Germany, to co-develop and commercialize TH-302, Threshold's small molecule hypoxia-targeted drug. TH-302 is currently being investigated in a global Phase 3 clinical trial in patients with soft tissue sarcoma, a randomized Phase 2 trial in patients with advanced pancreatic cancer from which top-line results are expected in February, as well as additional clinical studies in other solid tumors and hematological malignancies. Under the terms of the agreement, Merck will receive co-development rights, exclusive global commercialization rights and will provide Threshold an option to co-commercialize the therapeutic in the United States. In exchange, Threshold will receive an upfront payment of $25 million and could receive up to $35 million in additional development milestones during 2012. Threshold is also eligible to receive a $20 million milestone payment based on positive results from its randomized Phase 2 trial in pancreatic cancer. Total potential milestone payments are $525 million, comprised of $280 million in regulatory and development milestones and $245 million in sales-based milestones. In the United States, Threshold will have primary responsibility for development of TH-302 in the soft tissue sarcoma indication. Threshold and Merck KGaA will jointly develop TH-302 in all other cancer indications being pursued. Merck KGaA will pay 70% of worldwide development costs for TH-302.
