A Study to Assess the Independent Effects of 4-Factor Prothrombin Complex Concentrate and Tranexamic Acid on Bleeding/Pharmacodynamics in Healthy Participants
brief summary
The purpose of this study is to assess the independent effects of both a 4-Factor prothrombin complex concentrate (PCC) - (Kcentra) and Tranexamic acid (TXA) on the bleeding parameters (bleeding duration and blood volume) following a punch biopsy, in addition to assessing their effects on the anticoagulant/pharmacodynamic (prothrombin time and endogenous thrombin potential) changes induced by rivaroxaban at steady state, to better understand their potential role in bleeding reversal.
detailed description
This is a 2 part, single center study to be conducted in healthy men and women. Part 1 (open-label) consists of Screening Phase (within 28 days before admission into the study center on Day -1), followed by a 3 day treatment period and a follow-up visit on Day 8. A single oral 20 milligram (mg) dose of rivaroxaban will be administered on Day 1. Pharmacokinetic (PK), pharmacodynamics (PD), and punch biopsy parameters will be assessed. Part 2 (double-blind) consists of Screening Phase (within 28 days before admission into the study center on Day -1), followed by a 8 day treatment period (Day -1 to Day 7) and a follow-up visit on Day 11. Rivaroxaban (20 mg every 12 hrs) will be administered on Days 1 through 3 and single 20 mg dose will be given on the morning of Day 4. A single dose of either 4-factor PCC, TXA or saline (Placebo) will be administered in a randomized, blinded fashion on Day 4. PK, PD, Exploratory Bio-markers and punch biopsy parameters will be assessed. Participants' safety will be monitored throughout the study.
