Summary:

      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.
