Warfarin Sodium Tablets

Guangdong Raynovent Biotech Co., Ltd · Phase 3 active Small molecule ✓ Verified May 2026

Warfarin Sodium Tablets is a Vitamin K antagonist (coumarin anticoagulant) Small molecule drug developed by Guangdong Raynovent Biotech Co., Ltd. It is currently in Phase 3 development for Atrial fibrillation for stroke prevention, Venous thromboembolism (deep vein thrombosis and pulmonary embolism) treatment and prevention, Mechanical heart valve thromboprophylaxis. Also known as: Casopitant (GW679769) oral tablets.

Warfarin inhibits vitamin K-dependent clotting factors (II, VII, IX, X) by blocking the vitamin K epoxide reductase enzyme, thereby reducing thrombin generation and preventing blood clot formation.

Warfarin Sodium Tablets are used to treat conditions such as Atrial Fibrillation, Thromboembolism, and Aortic Valve Diseases. Warfarin Sodium Tablets are a type of Vitamin K antagonist, which is an intervention studied in clinical trials for anticoagulation therapy.

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

Mechanism of action

Warfarin is a coumarin anticoagulant that acts as a competitive inhibitor of vitamin K epoxide reductase, preventing the recycling of vitamin K and the gamma-carboxylation of clotting factors II, VII, IX, and X. This results in the production of inactive clotting factors and a prolonged prothrombin time (PT/INR). The anticoagulant effect develops over 36-72 hours as existing clotting factors are cleared from circulation.
