Bioequivalence of TTYP01 Tablets in Healthy Adult Subjects

This is a Phase 1, Randomized, Open-Label, Three-Treatment, Three-Period Crossover Study to Assess Bioequivalence and Safety of TTYP01 Tablets to Radicava® Injection, and Radicava ORS® in Healthy Adult Subjects Under Fasting Conditions.

The Primary objective is To characterize the bioequivalence of TTYP01 tablets (Test) and Radicava® injection (Reference 1) or Radicava ORS® (Reference 2) in healthy adult subjects under fasted conditions.

The secondary objective is To determine the safety and tolerability of TTYP01 tablets (Test), Radicava Injection (Reference 1), and Radicava ORS (Reference 2) in healthy adult subjects under fasted conditions.

In this open-label, randomized, 3-formulation, 3-period, crossover study, 30 healthy adult subjects will receive 1 single oral dose of 90 mg TTYP01 (3 tablets of the test drugs, test formulation T), or 1 injection of 60 mg Radicava (reference drug R1, intravenous infusion of 60 mg administered over 60 minutes), or 1 single oral dose of 105 mg/5 mL Radicava ORS (reference drug R2) after an overnight fast in each period according to the randomization sequence. Subjects will be randomized to 1 of 6 parallel sequences (5 subjects per sequence), with a washout period of at least 96 hours between the periods.

The approximate study period is 6 weeks, including screening and follow-up.
