April 4, 2024
By Karen Carey
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.

EMA’s CHMP backs new antibiotic, oral PNH drug in March meeting

March 26, 2024
By Jennifer Boggs
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.

GSK’s oral antibiotic hits endpoints in gonorrhea study

Feb. 26, 2024
By Jennifer Boggs
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.

FDA issues CRL for Venatorx’s antibiotic combo in UTIs

Feb. 23, 2024
By Jennifer Boggs
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.

UK further restricts use of fluoroquinolones

Jan. 24, 2024
By Mari Serebrov
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.

Old-fashioned screening approach yields new antibiotic class

Jan. 4, 2024
By Anette Breindl
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.

Explainable AI finds new class of antibiotics

Dec. 20, 2023
By Anette Breindl
Researchers have used explainable artificial intelligence (explainable AI) to find structurally new antibiotics with minimal toxicity. They reported their findings online in Nature on Dec. 20, 2023. In animal testing, compounds identified via the method showed that they had activity against drug-resistant gram-positive bacteria including methicillin-resistant Staphylococcus aureus (MRSA), one of the most serious bacterial public health threats.

New DAPG derivatives acting on bacterial cell membranes hold promise to treat MRSA infections

Dec. 13, 2023
The emergence of Staphylococcus aureus strains resistant to almost all approved antibiotics in the clinic poses an urgent public health concern. Thus, new antibiotics exploiting alternative antibacterial mechanisms or molecular structures are critically needed to address the long-term threat of multidrug-resistant S. aureus, particularly methicillin-resistant S. aureus (MRSA).

Cage fight could make for resistance-resistant antibiotic

Aug. 23, 2023
By Nuala Moran
A newly discovered antibiotic has been shown to block the synthesis of bacterial cell walls via immutable targets, raising the prospect of a class of drugs that will not lose effect through the development of antimicrobial resistance. Clovibactin, isolated from soil bacteria, targets the cell wall precursor molecules lipid II, lipid III and undecaprenyl phosphate (C55PP), all of which have a pyrophosphate group in common.
