Link to the current ClinicalTrials.gov record.

Condition(s) targeted: Healthy

Intervention: warfarin sodium (Drug); mipomersen sodium; warfarin sodium (Drug)

Phase: Phase 1

Status: Completed

Sponsored by: Genzyme, a Sanofi Company

Official(s) and/or principal investigator(s):
Medical Monitor, Study Director, Affiliation: Genzyme, a Sanofi Company

Summary

The purpose of this study is to assess how blood clotting and thinning time is effected when a single dose of warfarin is given alone and when a single dose of warfarin is given with mipomersen; to assess the blood levels of a single dose of warfarin, a single dose of mipomersen, and a single dose of warfarin when given with mipomersen; and to assess the safety of mipomersen when given with or without warfarin.

Clinical Details

Official title: A Drug-Drug Interaction Study to Assess the Effects of Multiple Doses of Mipomersen (200 mg SC) on Single-Dose Warfarin (25 mg) Pharmacodynamics and Pharmacokinetics in Healthy Adult Subjects

Study design: Allocation: Non-Randomized, Endpoint Classification: Pharmacokinetics/Dynamics Study, Intervention Model: Crossover Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Area under the effect curve (AUC), for INR (international normalized ratio), PT (prothrombin time), and aPTT (activated partial thromboplastin time)

Maximal Value (MAX) for INR, PT and aPTT

Time of maximal effect (Tmax) for INR, PT, and aPTT

Secondary outcome:

Warfarin Plasma Pharmacokinetic parameters (AUC 0-t, AUC 0-inf, Maximum Concentration (Cmax))

Mipomersen Plasma Pharmacokinetic parameters (AUC0-t, AUC0-inf, Cmax)

Incidence of treatment-emergent Adverse Events

Detailed description: This will be a Phase 1, open-label, single-sequence, 2-period, crossover study to determine the effect of multiple doses of mipomersen (200 mg SC given every other day for a total of 4 doses) on the PD and PK of warfarin and to evaluate the PK of mipomersen when administered

alone and in combination with warfarin. Subjects will be admitted to the clinic on Day - 1

until discharge from the clinic on Day 18 and return for outpatient visits on Days 19, 20, and 78. All subjects will receive a single 25-mg oral dose of warfarin given alone on Day 1 (designated the reference treatment). All subjects will then receive 200-mg SC doses of mipomersen given every other day on Days 8, 10, 12, and 14 (total of 800 mg mipomersen) with a single 25-mg oral dose of warfarin also given on Day 14 (combination designated the test treatment).

abuse or drug addiction.
