Brief summary
This Phase 1 open-label study enrolls 24 healthy Chinese adults to investigate the pharmacokinetics, safety and tolerability of oral IPG1094 tablets. The trial includes two parts. Part A (12 participants) uses a crossover design to explore the impact of food on a single 200 mg dose of IPG1094; participants will receive the drug under fasting and post-meal conditions on separate days, with intensive blood sampling for PK analysis. Part B (12 participants) evaluates multiple-dose PK, where participants take 200 mg IPG1094 twice daily for 10 days to observe drug exposure and accumulation. All participants will undergo comprehensive safety checks such as lab tests, ECG and adverse event monitoring during screening, treatment and post-dosing follow-up. No placebo or blinding is applied in this study.
Interventions
Part A:Oral administration with 240 mL water; fasted: ≥10h overnight fast, no water 1h before/after dosing; fed: take drug within 30 mins of finishing standardized high-fat breakfast. Single dose 200 mg per cycle, two cycles separated by 5-day washout. Part B:Oral 200 mg twice daily, morning \& evening, continuous 10 days; each dose taken with 240 mL water, restricted water intake 1h pre/post dose; steady-state PK sampling for accumulation assessment.

| Part A:Time to maximum concentration (Tmax) | Full PK sampling profiles on Day 1 and Day 6 | The time elapsed from IPG1094 administration to the occurrence of Cmax under fasting and high-fat fed states, summarized by median values per treatment sequence. |
| Part A:Plasma maximum concentration (Cmax) | Full PK sampling profiles on Day 1 and Day 6 | The maximum observed plasma concentration of IPG1094 after a single 200 mg oral dose under fasting and high-fat fed conditions, calculated via non-compartmental analysis (NCA). |
| Part A:Terminal elimination half-life (t1/2) | Serial blood samples collected up to 96 hours post-dose on Day 1 and Day 6 | Description: Terminal elimination half-life of IPG1094 following single-dose administration in fasting and high-fat fed regimens, derived from the terminal log-linear elimination phase of concentration-time curves. |
| Part B:Steady-state maximum plasma concentration (Css,max) | Full PK sampling profiles on Day 10 | The maximum observed steady-state plasma concentration of IPG1094 after continuous twice-daily 200 mg dosing for 10 days, calculated via non-compartmental analysis (NCA). |
| Part B:Time to steady-state maximum concentration (Tss,max) | Full PK sampling profiles on Day 10 | The time elapsed after the Day 10 morning dose to reach steady-state peak concentration (Css,max), presented as descriptive statistics. |
| Part B:Steady-state terminal elimination half-life (t1/2) | Serial blood samples collected up to 72 hours post-dose on Day 10 | Terminal elimination half-life of IPG1094 at steady state after repeated twice-daily dosing, calculated from the log-linear terminal elimination phase of Day 10 concentration-time curve. |
