AbbVie gets USFDA nod for Emblaveo for treatment of adults with complicated intra abdominal infections with limited or no treatment option

AMR is considered an urgent global public health threat and could lead to over 39 million deaths worldwide by 2050. An estimated 1.14 million deaths globally were attributed to bacterial AMR in 2021 alone. If AMR remains unaddressed, minor infections and routine surgical procedures could become life-threatening or fatal. The FDA has prioritized the research and development of new medicines to treat AMR and help prevent the spread of infection.

"As bacteria evolve, industry, government, and clinical experts must work together to ensure that the infectious disease community has the tools to advance public health," said Roopal Thakkar, M.D., executive vice president, research & development, chief scientific officer, AbbVie. "We're proud to offer this important novel treatment option to urgently address the significant threat of antimicrobial resistance."

EMBLAVEO is a medication that combines two components: aztreonam, a monobactam antibiotic, and avibactam, a β-lactamase inhibitor that protects aztreonam from serine β-lactamase hydrolysis and restores its activity against bacteria that co-produce Metallo-β-lactamases (MBLs) and serine β-lactamases. MBLs are a type of enzyme produced by certain bacteria that can become resistant to antibiotics and are on the rise globally. The approval of EMBLAVEO was supported by prior findings regarding the efficacy and safety of aztreonam for the treatment of cIAI. It was also supported by clinical trial results from the Phase 3 REVISIT study, which evaluated the efficacy, safety, and tolerability of EMBLAVEO for the treatment of serious infections due to Gram-negative bacteria, including MBL-producing multidrug-resistant pathogens, for which there are limited or no treatment options.

In 2019, the FDA granted Qualified Infectious Disease Product (QIDP) Designation and Fast Track Designation for EMBLAVEO. The QIDP Designation provides certain incentives for the development of new antibiotics, including priority review and eligibility for the FDA's Fast Track Designation, and a five-year regulatory exclusivity extension. The Fast Track Designation is designed to facilitate the development of and accelerate the review of drugs to treat serious conditions that do not have sufficient treatment options.

EMBLAVEO will be available for commercial use in the U.S. in Q3 2025.
