Brief summary

The trial is designed to assess the safety and tolerability of TNX-102 2.4 mg and to compare the bio-availability of TNX-102 2.4 mg and cyclobenzaprine 5 mg tablets under fasting or fed conditions.

Detailed description

Single-center, randomized, open-label, single-dose, three-way-crossover trial is designed to assess the safety and tolerability of TNX-102 2.4 mg (a dose based on the results of a previous Phase 2a, proof-of-concept study - VPI-CY-0001.1) and to compare the rate and extent of absorption of TNX-102 2.4 mg and cyclobenzaprine 5 mg tablets under fasting or fed conditions.

Interventions

DRUGTreatment A

TNX-102 2.4 mg - 1 gelcap once under fasting conditions.

DRUGTreatment B

Cyclobenzaprine 5 mg, 1 tablet once under fasting conditions

DRUGTreatment C

TNX-102 2.4 mg, 1 gelcap once given under fed conditions.
