BV100 (300 mg)

BioVersys SAS · Phase 3 active Small molecule ✓ Verified May 2026

BV100 (300 mg) is a Benzoxaborole antibiotic Small molecule drug developed by BioVersys SAS. It is currently in Phase 3 development for Serious bacterial infections caused by resistant gram-negative organisms (Phase 3 development). Also known as: Rifabutin for Infusion.

BV100 is a benzoxaborole antibiotic that inhibits bacterial leucyl-tRNA synthetase, disrupting protein synthesis in susceptible pathogens.

BV100 is a small molecule (modality) with the synonym MG-S-2525, used in clinical trials for various bacterial infections, including Ventilator Associated Pneumonia, Ventilator Associated Bacterial Pneumonia, Hospital Acquired Bacterial Pneumonia, Blood Stream Infection, and Meningitis. It has been studied in combination with other antibiotics, such as polymyxin B and ceftazidime/avibactam, in clinical trials.

Likelihood of approval
60.3% vs 58.3% industry baseline
If approved by FDA: likely 2028–2030
Steps remaining: NDA/BLA submission
Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Anti-infectives pathway favourability +2.0pp
    Microbiological endpoints + non-inferiority designs raise approval rates above baseline.
Predicted approval windows by jurisdiction (conditional on FDA approval)
Regulator Country Likely year Lag vs FDA
FDA US 2028–2030
EMA EU 2029–2031 +0.7 yr
MHRA GB 2029–2031 +0.7 yr
Health Canada CA 2029–2032 +0.9 yr

Mechanism of action

Benzoxaboroles are a novel class of boron-containing compounds that bind to the editing site of leucyl-tRNA synthetase, preventing the aminoacylation of tRNA and thus blocking bacterial protein synthesis. This mechanism is distinct from conventional antibiotics and may provide activity against drug-resistant organisms. BV100 is being developed for serious bacterial infections, particularly those caused by resistant gram-negative pathogens.
