ClinConnect Summary

This clinical trial is studying a new medicine called HS-10542 to see if it is safe and well-tolerated in healthy adults. The study will also look at how the body processes the medicine and whether food affects this process. This is an early-stage trial, which means it focuses mainly on safety rather than treating any illness.

People between the ages of 18 and 64 who are generally healthy may be eligible to join. Participants need to have a body weight and body mass index (BMI) within a certain healthy range, and they must pass a series of health checks like blood tests, heart monitoring, and imaging scans to ensure no serious health issues are present. Women must agree to use effective birth control during and after the study, and men who can father children must also use birth control. Participants should be able to communicate clearly, understand the study, and agree to follow its requirements.

If you take part, you can expect to receive either the study medicine or a placebo (a harmless “dummy” pill), but neither you nor the study staff will know which one you get until the trial is over. The study involves taking different doses to understand how the medicine behaves in the body, and you may be asked to fast or eat specific meals to see how food affects the medicine. There will be several medical tests and blood draws throughout the study to monitor your health and how your body responds. The trial is looking for volunteers who do not have any major health problems, do not use certain medications or substances, and can commit to the study schedule and rules.

Eligibility criteria

• • Inclusion Criteria：
• • 1. Male or female between 18 and 64 years of age (critical values inclusive) when signing the informed consent form.
• • 2. Body mass index (BMI = weight/height2) ≥ 19 kg/m2 and ≤ 28 kg/m2 at screening, and body weight ≥ 50 kg for men and ≥ 45 kg for women.
• • 3. Physical examination, laboratory tests, 12-lead ECG, abdominal B-ultrasound and anteroposterior and lateral chest X-ray (or CT) examination showed no abnormality, or slight abnormality but with no clinical significance as judged by the investigator, or slight abnormality but with controllable risk as judged by the investigator, and communication with the sponsor 's medical and pharmacological personnel is required when necessary;
• 4. Female participants are required to agree to practice highly effective contraception from 2 weeks before screening until 60 days after the last dose:
• • 5. Male participants of childbearing potential are required to agree to practice highly effective contraception from the date of signing the informed consent until 120 days after the last dose; male participants of non-childbearing potential (e.g, having undergone effective sterilization) are required to agree to use additional highly effective contraception in the event of uncertainty about the presence of sperm.
• • 6. Participants should be able to complete vaccinations against Neisseria meningitidis (types A, C, Y, and W-135) and streptococcus pneumoniae at least 2 weeks prior to the first dose, and if participants have previously received the above vaccines, antibody titers or vaccine manufacturer information should be provided, and booster vaccinations should be completed as needed according to local practice guidelines in the opinion of the investigator to obtain adequate protection during the trial.
• • 7. The participants are able to communicate clearly with the investigator, understand and comply with the requirements of this trial, have a comprehensive understanding of the study content, process and possible adverse reactions, and sign the informed consent forms voluntarily.
• Exclusion Criteria:
• • 1. Consumed any caffeinated, tea, alcohol, xanthine-rich foods or beverages within 24 hours before administration.
• • 2. Consumed foods known to alter hepatic enzyme activity (eg, pitaya, grapefruit, Seville oranges, etc) and their juice drinks within 1 week before administration.
• 3. Abnormal vital signs, physical examination, laboratory tests, 12-lead ECG, chest anteroposterior X-ray/CT examination, abdominal ultrasonography, etc. at the time of screening are clinically significant and, as assessed by the investigator, may increase the risk for the participant or affect the interpretation of the study results, which include but are not limited to:
• • 1. Abnormal liver function: alanine aminotransferase (ALT) or aspartate aminotransferase (AST) or total bilirubin (TBiL) ≥ 1.5 times ULN.
• • 2. Abnormal renal function: eGFR \< 60 mL/min/1.73 m2 at screening or abnormal renal function as judged by the investigator, calculated using the estimation formula of Chronic Kidney Disease Epidemiology Collaboration 2021 (CKD-EPI): eGFR (mL/min/1.73 m2) .
• • 3. Abnormal ECG: The absolute value of QTcF (QT interval corrected by Fridericia 's formula \[QT/RR0.33\]) \> 450 msec for males and \> 470 msec for females; or other clinically significant abnormalities as judged by the investigator.
• • 4. Positive hepatitis B virus surface antigen (HBsAg), or negative HBsAg but positive hepatitis B core antibody (HBcAb), or positive HCV Ab, or positive result of any test for HIV antibody or Treponema pallidum-specific antibody at screening and is assessed by the investigator as inappropriate to participate in this trial.
• • 5. participants with inactive, active or latent tuberculosis infection (indicated by tuberculosis on chest X-ray or CT, or positive T-SPOT.TB result) at screening who are assessed as inappropriate for participation in this trial by the investigator.

Washout periods for systemic medications or food are detailed in Section 6.7.
• • 8. Those who have been vaccinated with vaccines other than those specified in this protocol within 1 month before screening or are scheduled to be vaccinated within 1 month after the end of the administration.
