Detailed Description

This study is divided into three parts: PART-1, PART-2, and PART-3. It is planned that PART-2 will prioritize enrollment (all dose groups can be enrolled simultaneously), while PART-1 and PART-3 can also be enrolled concurrently. The doses for PART-1 and PART-3 may be adjusted based on the results of PART-2.

PART-1 (FE + Single-Dose PK Comparison):

A Single-Center, Randomized, Open-Label, Three-Period, Three-Sequence, Three-Way Crossover Study to Evaluate the Pharmacokinetic Characteristics and Food Effect of BM2216 Extended-Release Tablets After Single Oral Administration Under Fasting and High-Fat Meal Conditions in Healthy Adult Subjects, and to Compare the Pharmacokinetic Characteristics with Multiple-Dose Melogabalin Besilate Tablets, Relative Bioavailability, and Safety. This study plans to enroll 18 subjects, who will be randomly assigned to three dosing sequence groups in a 1:1:1 ratio.

PART-2 (Single-Dose Proportionality):

A single-center, open-label, parallel design will be used to evaluate the pharmacokinetic characteristics, dose proportionality, and safety of BM2216 extended-release tablets after a single dose in healthy adult subjects. This study plans to enroll 32 subjects, with four dose groups of BM2216 extended-release tablets (5.5 mg, 11 mg, 16.5 mg, and 33 mg), with 8 subjects in each group.

PART-3 (Multiple-Dose PK Comparison):

This study adopts a single-center, randomized, open-label, two-period, two-sequence, two-crossover design to evaluate the pharmacokinetic characteristics of BM2216 extended-release tablets after multiple oral doses in healthy adult subjects, as well as the pharmacokinetic comparison with multiple doses of mirogabalin besylate tablets, relative bioavailability, and safety. The study plans to enroll 16 subjects, who will be randomly assigned to two dosing sequence groups in a 1:1 ratio.
