KMY Tablets: KMY Tablets is an investigational drug product. This study evaluates its safety, tolerability, and pharmacokinetics in healthy subjects.
Placebo: A placebo tablet matching the appearance of the active KMY Tablets. It contains no active pharmaceutical ingredient.
Study summary
This is a Phase Ia, randomized, double-blind, placebo-controlled study conducted in healthy subjects. The study plans to enroll a total of 120 participants, with both males and females included in all parts.
The trial consists of three distinct parts:
Part A (Single-Ascending Dose, SAD): A total of 72 subjects will be enrolled to evaluate the safety, tolerability, and pharmacokinetics of single oral doses of KMY Tablets.
Part B (Multiple-Ascending Dose, MAD): A total of 36 subjects will be enrolled to evaluate the safety, tolerability, and pharmacokinetics of multiple oral doses of KMY Tablets.
Part C (Food-Effect): A total of 12 subjects will be enrolled to assess the impact of a high-fat, high-calorie meal on the pharmacokinetic profile of KMY Tablets.
The primary objectives are to evaluate the safety and tolerability of single and multiple doses of KMY Tablets and to assess the food effect on its pharmacokinetics. The secondary objectives include characterizing the single- and multiple-dose pharmacokinetics, investigating the drug's metabolism and excretion, and evaluating the safety and tolerability in the fed state. Exploratory pharmacodynamic parameters may also be investigated.

2. History or presence of severe chronic diseases of the cardiovascular, hepatic, renal, respiratory, hematological, endocrine, immune, psychiatric, or neurological systems within the past year, which in the investigator's judgment may compromise participant safety or study integrity.
3. Abnormal and clinically significant findings in vital signs, physical examination, laboratory tests (hematology, blood chemistry, urinalysis, coagulation), or 12-lead ECG at screening, as judged by the investigator.
4. Use of any medications (including prescription, over-the-counter, or herbal medicines) or health supplements within a specified period (e.g., 2 weeks) prior to screening.
5. Participation in another clinical trial (drug or medical device) or use of any other investigational drug within a specified period (e.g., 3 months) prior to screening.
6. History of drug abuse or positive urine drug screen.
7. Donation or loss of ≥400 mL of blood, or receipt of blood products, within a specified period (e.g., 6 months) prior to screening.
8. History of alcohol abuse, inability to abstain from alcohol during the study, or positive alcohol breath test.
9. Smoking more than a specified number of cigarettes per day (e.g., 5) within a specified period prior to screening, or inability to cease use of tobacco products during the study.
10. Intolerance to venipuncture or history of needle or blood phobia.
11. Any other condition that, in the investigator's opinion, may pose a risk to the participant or interfere with the evaluation of study results.
Additional Exclusion Criteria for Female Participants:
12. Pregnant or lactating women, or women with a positive pregnancy test.
13. Unwilling to use effective contraception during the study and for a specified period thereafter.
Primary outcome measure(s)
Safety and Tolerability: Incidence of Treatment-Emergent Adverse Events (TEAEs) — From first dose of study drug up to 7 days after the last dose (assessed up to approximately 4 weeks). The number and percentage of participants with all-cause adverse events (AEs), including serious adverse events (SAEs) and AEs leading to study drug discontinuation. Severity will be graded according to NCI CTCAE v5.0.
(Note: Specify the exact grading scale you use, e.g., NCI CTCAE v5.0)
Food Effect: Maximum Observed Plasma Concentration (Cmax) of KMY Tablets — Pre-dose, and at multiple timepoints up to 72 hours post-dose in each study period (Period 1 and Period 2). The maximum observed plasma concentration (Cmax) of KMY Tablets following a single oral dose under fed (high-fat, high-calorie meal) conditions compared to fasting conditions.
