Under the terms of the agreement, Tetraphase will receive an initial upfront payment of $7.0 million and may receive clinical and regulatory milestones of up to $16.5 million as well as annual sales milestones of up to $20.0 million.
Everest will be solely responsible for the development and commercialization of eravacycline in the Territories.
Tetraphase and Everest will establish a joint steering committee to review and oversee all of Everest’s development and commercialization plans. Tetraphase will also be eligible to receive double digit tiered royalties on net sales of eravacycline in the Territories.
Tetraphase president and CEO Guy Macdonald said: “Our agreement with Everest marks an important step in our plans to bring eravacycline to market on a global level.
“With positive Phase 3 data evaluating IV eravacycline in cIAI, our NDA under review by the FDA in the U.S. and our Marketing Authorization Application also under review in Europe, both for cIAI, we are expanding our commercialization strategy to China and other Asian territories and countries.
“With new regulations in place in China to accelerate development and approval, along with high levels of multidrug-resistant infections there, we believe there is a significant opportunity for eravacycline to become an important new treatment in China and other territories.
“We are excited to have Everest as a partner and expect their development and commercialization expertise, as well as strategy for leveraging changes in the regulatory environment, will be invaluable in maximizing the value of eravacycline in the Chinese market.
“We look forward to working with Everest to bring eravacycline to patients and addressing a critical unmet need in a region where viable treatment options are scarce.”
