What to Expect as a Participant

You will actively receive the study intervention — which may be a drug, biologic, device, or procedure.

Phase 1 is the earliest stage of human testing — safety and dosage are the primary focus. Visits are frequent and medical supervision is intensive. You will be among the first people to receive this treatment.

This trial targets 36 participants in total. It began in 2025-01-04 with a primary completion date of 2025-05-04.

Brief Summary

Y-4 is a new fixed-dose combination drug product containing two active ingredients of pregabalin and riluzole. The primary objective is to evaluate the safety and tolerability of Y-4 tablets in Chinese healthy adult subjects after single- and multiple-dose. The secondary objective is to characterize the pharmacokinetics (PK) of pregabalin and riluzole in Chinese healthy adult subjects after single- and multiple-dose of Y-4 tablets.

Eligibility Criteria

Inclusion Criteria: 1. Healthy adult male and female subjects, 18-45 years of age (including both ends). 2. Body weight ≥ 50 kg for male and ≥ 45 kg for female, body mass index (BMI) within the range of 19 - 28 kg/m2 (including both ends). 3. During the screening period, serum creatinine is within the normal range, or the standard creatinine clearance (CLcr) estimated by Cockcroft-Gault formula is ≥ 80 mL/min (for female subject, according to the calculation result × 0.85）. 4. Subjects who are able to understand and give their signed informed consent before any trial related procedures are performed. Exclusion Criteria: 1. Subjects who are known to be allergic to pregabalin, riluzole or any excipients of Y-4 tablets (microcrystalline cellulose, Copovidone, croscarmellose sodium, colloidal silicon dioxide, magnesium stearate and Opadry amb Ⅱ), have allergic diseases or allergic constitution; 2. Subjects who have special requirements for diet and cannot follow the unified diet; 3.
