Pfizer Inc. announced that it has completed the acquisition of the development and commercialization rights to AstraZeneca’s late-stage small molecule anti-infective business, primarily outside the United States. The agreement includes the commercialization and development rights to the newly approved EU drug Zavicefta (ceftazidime-avibactam), the marketed agents Merrem/Meronem (meropenem) and Zinforo (ceftaroline fosamil), and the clinical development assets aztreonam-avibactam (ATM-AVI) and CXL. Zavicefta specifically addresses certain multi-drug resistant Gram-negative infections, including those resistant to carbapenem antibiotics, one of the most significant unmet medical needs in bacterial infections treated with hospital anti-infectives.
