Optimised dose rifampicin

Radboud University Medical Center · Phase 3 active Small molecule Under review Quality 0/100

Optimised dose rifampicin is a Antibiotic (rifamycin) Small molecule drug developed by Radboud University Medical Center. It is currently in Phase 3 development for Tuberculosis (optimised dosing regimen).

Optimised dose rifampicin inhibits bacterial RNA polymerase to suppress mycobacterial protein synthesis and growth.

Rifampicin is a small molecule that inhibits bacterial DNA-directed RNA polymerase, classified as an inhibitor. It is being studied in clinical trials, including the Pragmatic Optimized Rifampicin Trial (PORT), for its safety and tolerability in treating conditions such as tuberculosis and pulmonary tuberculosis.

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)

Mechanism of action

Rifampicin is a well-established antibiotic that binds to bacterial RNA polymerase, blocking transcription and translation in mycobacteria. The optimised dosing regimen aims to improve pharmacokinetic exposure and efficacy while maintaining tolerability in tuberculosis treatment. This approach seeks to enhance bacterial killing and potentially shorten treatment duration.
