“Entasis remains committed to building a pipeline of life-saving treatments for patients affected by drug-resistant bacterial infections around the world. We are thrilled to partner with Zai Lab on the further development and potential commercialization of ETX2514SUL in the Asia-Pacific region, most notably in Greater China, where the rate of A. baumannii infections rank among the highest in the world," said Manos Perros, Chief Executive Officer of Entasis. "With their experienced leadership team, focus on innovation and established expertise and network within the infectious diseases arena, Zai Lab is the ideal partner to help bring ETX2514SUL to the numerous patients in the region who need a new effective treatment option. The collaboration will offset costs and enable enrollment of patients from China into our global Phase 3 clinical trial, further supporting our plans to rapidly progress ETX2514SUL to market.”
“Infectious diseases are a key focus area for Zai Lab due to the serious problem of multidrug-resistant infections both in China and globally. We are excited to collaborate with Entasis, a company that has extensive expertise and know-how in developing anti-infective products that address multidrug-resistant infections, and we look forward to working together to accelerate the global development of this potential life-saving therapy. We expect ETX2514SUL will be a positive addition to Zai Lab ’s anti-infective portfolio, and we remain committed to developing a drug to combat multidrug-resistance, which currently poses a serious global threat to our society,” stated Samantha Du, Ph.D., Chairman and Chief Executive Officer of Zai Lab. “This collaboration reinforces the strength of the Zai Lab team both in China and globally, and we believe will help us further progress on our mission to establish Zai Lab as an innovative, fully integrated, global pharmaceutical company.”
Under the terms of the agreement, Entasis has granted Zai Lab an exclusive license to develop and commercialize ETX2514SUL in specified countries in the Asia-Pacific region, including Japan. Entasis and Zai Lab will cooperate in conducting a pivotal Phase 3 trial in China, with Zai Lab taking the lead by conducting the screening, enrollment and treatment of patients, and coordinating development, registration and commercialization of ETX2514SUL in the territory. In addition, Entasis and Zai Lab have an option to collaborate on the development and commercialization of ETX2514 in combination with other active ingredients. A joint steering committee will be formed between the companies to oversee development, regulatory and commercialization activities in the Asia-Pacific territory. In addition to financial support for the portion of the Phase 3 trial conducted in China, Entasis will receive a $5 million upfront payment and is eligible to receive up to an aggregate of $7.6 million in near-term development milestones and up to an aggregate of $91.0 million in additional development, regulatory and sales milestone payments related to ETX2514SUL and other combinations, plus royalties.
About Acinetobacter baumannii Infections
A. baumannii is a Gram-negative bacterium causing severe infections associated with high mortality and has emerged as a cause of numerous global outbreaks, displaying ever-increasing rates of antibiotic resistance, which greatly limits treatment options. Consequently, the World Health Organization (WHO) has placed carbapenem-resistant A. baumannii at the top of its list of “Critical” priority pathogens for new antibiotics. The U.S. Centers for Disease Control (CDC) also recognizes A. baumannii as a serious public health threat and estimates that 63% of A. baumannii are multidrug-resistant.
In China, A. baumannii accounts for approximately 11% of total Gram-negative infections. Based on a national surveillance of over 1,300 hospitals in China, there are over 200,000 A. baumannii infections per year, although the actual incidence is estimated to be much larger. The resistance of A. baumannii to the carbapenem class of antibiotics has increased significantly, estimated at 60% in 2016, with some provinces as high as 70-80%. In other Asia-Pacific countries, such as Japan and Korea, it has also become an increasingly significant challenge for physicians. Due to the high rates of multidrug-resistant infections, the Chinese government has identified the goal of developing one to two innovative anti-infective drugs by 2020.
ETX2514 is a novel broad-spectrum intravenous inhibitor of class A, C and D beta-lactamases. ETX2514 restores the in vitro activity of multiple β-lactams against Gram-negative, multidrug-resistant pathogens. Entasis is initially developing ETX2514SUL, a fixed-dose combination of ETX2514 and sulbactam, for the treatment of a variety of serious multidrug-resistant infections caused by A. baumannii. Sulbactam is a generic β-lactam that has intrinsic activity against A. baumannii but suffers from widespread β-lactamase-mediated resistance. In preclinical studies, ETX2514 restored sulbactam antibacterial activity against A. baumannii. ETX2514 has completed single- and multi-ascending dose Phase 1 trials. The U.S. Food and Drug Administration has granted Qualified Infectious Disease Product (QIDP) designation and Fast Track designation to ETX2514SUL for the treatment of hospital-acquired and ventilator-acquired bacterial pneumonia and bloodstream infections due to A. baumannii.
Entasis is a clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of novel antibacterial products to treat serious infections caused by multidrug-resistant Gram-negative bacteria. Entasis’ targeted-design platform has produced a pipeline of product candidates, including ETX2514SUL (targeting A. baumannii infections), ETX0282CPDP (targeting Enterobacteriaceae infections), and zoliflodacin (targeting Neisseria gonorrhoeae). Entasis is also using its platform to develop a novel class of antibiotics, non-β-lactam inhibitors of the penicillin-binding proteins (NBPs) (targeting Gram-negative infections).
