RBT-1

Renibus Therapeutics, Inc. · Phase 3 active Small molecule Under review

RBT-1 is a ACE inhibitor Small molecule drug developed by Renibus Therapeutics, Inc.. It is currently in Phase 3 development for Hypertension.

RBT-1 is a small molecule that targets the renin-angiotensin system to treat hypertension.

RBT-1 is a treatment being studied in a Phase 1b clinical trial for conditions such as Acute Kidney Injury, Post-Operative Complications in Cardiac Surgery, and Chronic Kidney Disease. The trial is being conducted by Renibus Therapeutics, Inc. to assess the safety and efficacy of RBT-1 in healthy volunteers and subjects with Chronic Kidney Disease Stage 3b-4.

Likelihood of approval
56.3% 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).
  • Cardiovascular Phase 3 risk -2.0pp
    Modern cardiovascular outcome trials are large + long; many fail to beat aggressive standard-of-care.
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

Mechanism of action

RBT-1 works by inhibiting the angiotensin-converting enzyme (ACE), which is a key component of the renin-angiotensin system. This leads to decreased levels of angiotensin II, a potent vasoconstrictor, resulting in vasodilation and reduced blood pressure.
