Entasis Therapeutics and Zai Lab Complete Patient Enrollment in the ATTACK Phase 3 Registrational Clinical Trial of Sulbactam-Durlobactam
– First clinical trial to specifically study confirmed carbapenem-resistant Acinetobacter infections–
WALTHAM, Mass. and SHANGHAI, China and SAN FRANCISCO, July 27, 2021 (GLOBE NEWSWIRE) -- Entasis Therapeutics Holdings Inc. (NASDAQ:ETTX), a clinical-stage biopharmaceutical company focused on the discovery and development of novel antibacterial products, and Zai Lab Limited (NASDAQ:ZLAB; HKEX: 9688), an innovative commercial-stage biopharmaceutical company, announced today that patient enrollment in the ATTACK Phase 3 registrational clinical trial of sulbactam-durlobactam (SUL-DUR) is now complete, with top-line data readout anticipated early in the fourth quarter of 2021.
David Altarac, M.D., Chief Medical Officer at Entasis, commented, “Completion of ATTACK enrollment is a significant milestone for our companies, and we thank the patients and their families, healthcare professionals and our partner, Zai Lab, for the collective efforts that enabled us to reach full enrollment during these challenging times. To our knowledge, ATTACK is the largest antibiotic-resistant, pathogen-specific registrational trial to be conducted globally and the first to focus specifically on carbapenem-resistant Acinetobacter infections. We look forward to announcing top-line data in the coming months.”
Harald Reinhart, M.D., Chief Medical Officer for Autoimmune and Infectious Diseases at Zai Lab, stated, “Infections caused by carbapenem-resistant Acinetobacter spp. (CRAB) are extremely difficult to manage and associated with high mortality, as safe and effective antibiotics against such strains are often no longer available. In many countries, including China, this problematic pathogen is frequently isolated from patients in the ICU setting. We believe that SUL-DUR is uniquely suited to address this high unmet medical need and are proud that Chinese clinical centers contributed significantly to the ATTACK trial.”
ATTACK is a Phase 3 registrational trial that will evaluate the safety and efficacy of SUL-DUR in patients with confirmed carbapenem-resistant Acinetobacter infections. Part A of the trial, which evaluates the efficacy of SUL-DUR compared to colistin on a background of imipenem in patients with pneumonia and/or bloodstream infections, with 28-day all-cause mortality as the primary efficacy endpoint, has now enrolled over 120 patients, sufficient to complete the trial. Approximately one-quarter of the patients in Part A, the primary efficacy arm of the trial, were enrolled in China. Part B of the trial, which enrlled over 25 patients, is a non-randomized cohort of patients with confirmed Acinetobacter infections that are treated with SUL-DUR but are not eligible for Part A due to factors that could include colistin resistance, colistin intolerance or Acinetobacter infection in another body site unresponsive to colistin therapy.
