A team led by Paul Hergenrother at the University of Illinois, Urbana Champaign (UIUC) has developed a novel antibiotic named lolamicin that was specific for gram-negative bacteria but did not harm the gut microbiome composition in mouse models.
The U.K.’s world-first subscription model for antimicrobials is to be expanded following a successful pilot scheme in which companies are being paid a fixed annual fee for their drugs, regardless of the volume dispensed.
A team from the University of Southern Denmark has reported the discovery of a novel triaromatic pleuromutilin antibiotic candidate for the treatment of gram-positive bacterial infections. Hit evaluation and optimization of previously reported drug-like pleuromutilin conjugates with broad antibacterial activity led to the identification of compound [I] as the most potent and easily synthesizable antibiotic lead.
In a long and winding regulatory road that began with two complete response letters 15 years ago, Allschwil, Switzerland-based Basilea Pharmaceutica Ltd. finally gained U.S. FDA approval of its intravenous cephalosporin antibiotic, Zevtera (ceftobiprole medocaril sodium), to treat Staphylococcus aureus bacteremia, acute bacterial skin and skin structure infections (ABSSSI) and community-acquired bacterial pneumonia.
The EMA’s Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending approval of Pfizer Inc.’s Emblaveo (aztreonam-avibactam), an antibiotic combination that would offer a new option to patients with serious bacterial infections caused by multidrug-resistant gram-negative bacteria.

If approved, Emblaveo would be among the first beta-lactam/beta-lactamase inhibitor combos cleared for use in Europe.
With a regulatory filing expected later this year for gepotidacin based on positive data in uncomplicated urinary tract infections, GSK plc reported that the potentially first-in-class oral antibiotic hit its endpoints in a phase III trial in uncomplicated urogenital gonorrhea, the sexually transmitted disease facing a rise in incidence rate and increased antibiotic resistance.
The good news is that the U.S. FDA’s complete response letter (CRL) for Venatorx Pharmaceuticals Inc.’s intravenous antibiotic combination, cefepime-taniborbactam, in complicated urinary tract infections (cUTIs) requested no additional clinical testing. The bad news is the inevitable delay for a drug Venatorx and partner Melinta Therapeutics Inc. are aiming to position as a much-needed option for the fight against drug-resistant gram-negative infections.
Making them an antibiotic of last resort, the U.K.’s Medicines and Healthcare Products Regulatory Agency introduced new restrictions on the use of fluoroquinolones due to the risk of potentially long-term or irreversible side effects.
Researchers have identified a new class of antibiotics that works by blocking the transportation of lipopolysaccharide (LPS) to the outer membrane of the gram-negative bacterium Acinetobacter baumannii. The most advanced member of the class, zosurabalpin (RG-6006, Roche AG), was effective against multiple A. baumannii strains, including carbapenem-resistant and multidrug-resistant strains.
