Primary Outcome Measures:
  • Measure the absorption of serum Civamide through pharmacokinetics assessments [ Time Frame: 4 days ]

Estimated Enrollment: 12
Study Start Date: November 2008
Study Completion Date: July 2009
Primary Completion Date: June 2009 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: Cohort 1
Civamide liquid filled softgel capsule 5 mg
Drug: Civamide
5 mg liquid filled softgel capsules
Other Name: oral civamide
Active Comparator: Cohort 2
Civamide liquid filled soft gel capsules 2 x 5 mg
Drug: Civamide
5 mg x 2 liquid softgel capsules
Other Name: oral civamide

Detailed Description:

This is an open-label, non-randomized pharmacokinetic study of two dosage strengths of oral Civamide. The study consists of a Screening Period (Days -21 to Day -2), an Admittance Period, A 4 Day in-house Treatment Period(Days 1-4))and a follow-up Visit on Day 7.

Pharmacokinetics will be assessed at specified timepoints relative to dosing on Day 1 during the in-house stay. Subjects will be discharged from the research unit following the 72 hr blood draw.

Subjects will return to the research unit on Day 7 for a follow-up safety assessment.
