A Study of TTYP01 in Healthy Adult Subjects

A Phase I, Single Center, Randomized, Single-Ascending Dose, Pharmacokinetic and Safety Study (Part A), Bioavailability Comparison Study (Part B) and Food Effect Study (Part C) in Healthy Adult Subjects.

This is integrated Phase 1, Single centre, Randomized study will be conducted in 3 parts, each with a specific primary objective:

Part A: To characterise the safety and tolerability of TTYP01 in healthy adult subjects; Part B: To evaluate the bioavailability of TTYP01 tablets in healthy adult subjects; Part C: To characterise the food effect of TTYP01 tablets in healthy adult subjects under the fasted or fed condition.

The secondary objectives of the study are to evaluate the pharmacokinetic (PK) profiles of TTYP01 tablets in healthy adult subjects, and the effects of gender on the PK of TTYP01 tablets in healthy adults. In Part A of the study, a total of 32 healthy adult subjects will be enrolled over four consecutive cohorts (8 per cohort), with participants receiving a single dose of TTYP01 at one of four levels (60, 120, 10 or 240 mg), to assess the PK and safety of TTYP01. In Part B, 16 healthy adults will be randomized into 2 groups, and the comparison of the PK of edaravone (TTYP01 and intravenous (IV) edaravone) will be evaluated using a randomized, open-label, four-period crossover design under fasted conditions. In the first crossover period, subjects will receive a single fixed dose of TTYP01 followed by the alternate IV dose after completion of the washout phase, and in the second crossover period, subjects will receive a higher fixed dose of TTYP01 followed by the alternate IV dose after completion of the washout phase. In Part C, 18 healthy subjects will be enrolled to evaluate the effect of food on the PK of TTYP01 using a randomized, open-label, two-period cross-over design. Participants will be randomized into two groups and administered a fixed dose of TTYP01 on Day 1 (Period 1) under the fed conditions and the second dosing day (Period 2) under the fasted conditions, while the other group being administered a fixed dose of TTYP01 on Day 1 (Period 1) under the fasted conditions and the second dosing day (Period 2) under the fed conditions.
