Key Developments:

In June 2024, Orchid Pharma, known for its innovative drug development, partnered with Cipla, a pharmaceutical company, to launch Cefepime-Enmetazobactam in India. The antibiotic is approved for treating complicated urinary tract infections (cUTI), hospital-acquired pneumonia (HAP), and ventilator-associated pneumonia (VAP). This collaboration leverages Orchid Pharma’s drug innovation and Cipla’s vast distribution network, aiming for widespread access.
On April 3, 2024, the U.S. Food and Drug Administration (FDA) approved Zevtera (ceftobiprole medocaril sodium) for treating adults with Staphylococcus aureus bloodstream infections (SAB), including right-sided infective endocarditis; acute bacterial skin and skin structure infections (ABSSSI); and community-acquired bacterial pneumonia (CABP) in patients aged three months to under 18 years
In June 2023, Pfizer, a pharmaceutical company, announced successful Phase 3 results for its investigational antibiotic combination aztreonam-avibactam (ATM-AVI). The studies, REVISIT and ASSEMBLE, demonstrated that ATM-AVI is effective and well-tolerated in treating Gram-negative bacterial infections, including those caused by multidrug-resistant pathogens like metallo-β-lactamase (MBL) producers.

Top Strategies Followed by Global Antibacterial Drugs Market Players

Established Players: Leading pharmaceutical companies are significantly increasing their research and development (R&D) expenditures to innovate high-performance antibacterial products.
- For instance, in 2023, Merck & Co. invested US$ 30.5 billion in R&D, representing 50.8% of its total revenue, with a substantial portion dedicated to partnerships and acquisitions aimed at enhancing their antibacterial portfolio.
Mid-Level Players: Companies, such as Merck & Co., Sanofi, and Novartis, focus on delivering affordable treatment options.
