Bioequivalence Study of TNX-102 SL 2.8 mg Sublingual Tablets From Two Manufacturers.

A SINGLE-DOSE, RANDOMIZED, OPEN-LABEL, TWO-WAY CROSSOVER BIOEQUIVALENCE STUDY OF TNX-102 SL (CYCLOBENZAPRINE HCL SUBLINGUAL TABLETS) 2.8 mg FROM TWO MANUFACTURERS IN HEALTHY SUBJECTS UNDER FASTING CONDITIONS

This study is an open-label, 2-way crossover, single-dose study that is being performed to establish the bioequivalence of TNX-102 SL 2.8 mg tablets from two manufacturers: manufacturer of the Phase 2/3 drug product and manufacturer of the Phase 3 and commercial drug product. This bioequivalence study will confirm (1) the drug product manufactured from these two manufacturers are therapeutically equivalent and (2) the efficacy and safety data obtained in clinical studies using TNX-102 SL from these two manufacturers are comparable.

Study Overview

• Status: Completed
• Conditions: Healthy Adults
• Intervention / Treatment: Drug: Treatment A; Drug: Treatment B

Detailed Description

This will be a single centre, bioequivalence, open-label, randomized, single-dose, 2-period, 2 sequence, crossover study under fasting conditions.

Potential subjects will be screened by medical and psychiatric history, and laboratory and physical examinations 2 to 30 days prior to drug administration. All eligible subjects will be admitted to the study unit on Day -1, the day prior to dose administration. Baseline values will be considered the last value obtained before dosing for each assessment. On Day 1, the morning after admission, after all pre-dose assessments have been completed and subjects who remain eligible have agreed to continue, subjects will be randomly assigned to study medication and will receive the assigned test drug. Subjects will be required to fast for at least 10 hours prior to dosing until at least 4 hours post-dose.

For each period, subjects will be confined to the study site from at least 10 hours before dosing until after the 24-hour post-dose blood draw. Subjects will come back for all subsequent blood draws. Subjects will be reassessed for eligibility prior to each dosing period.
