A Single Ascending Dose Study to Assess the Safety, Tolerability, Pharmacokinetics and Pharmacodynamics of CITY-FXI in Healthy Adults, Adults With FV Leiden or Prothrombin G20210A Mutation, and Adults With a History of Provoked Venous Thromboembolism
A Phase 1, Randomised, Double-Blind, Placebo-Controlled Single Ascending Dose Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Pharmacodynamics of CITY-FXI, a FXI Targeting siRNA, Administered Subcutaneously in Healthy Adults, Adults With Factor V Leiden or Prothrombin G20210A Mutation, and Adults With a History of Provoked Venous Thromboembolism
This is a first-in-human (FIH), single-center, randomized, double-blind, placebo-controlled, single ascending and multiple dose study evaluating the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of CITY-FXI in healthy adults, adults with Factor V Leiden (FVL) or prothrombin G20210A mutation, and adults with a history of provoked venous thromboembolism (VTE).
