Experimental HIV immune therapy takes first step in healthy volunteers

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: 1. Voluntary participation in the study, ability to understand and comply with the protocol requirements, and provision of written informed consent. 2. Physical examination, vital signs, 12-lead electrocardiogram, and laboratory tests (hematology, urinalysis, serum chemistry, infectious disease screening, coagulation) are normal or have no clinically significant abnormality. 3. Male or female, age 18 to 55 years inclusive. 4. Body weight: male ≥50.0 kg, female ≥45.0 kg. Body mass index (BMI) between 18.0 and 26.0 kg/m² inclusive. BMI = weight (kg) / height (m)². 5. No clinically significant history of cardiovascular, hepatic, renal, gastrointestinal, neurological, or hematological disease. 6. No plans for pregnancy within 6 months, and agreement to use effective contraception with their partner from screening until 3 months after the study completion. No donation of sperm or eggs during this period. Exclusion Criteria: 1. Any history of allergic disease, or food or drug allergy, that in the investigator's opinion makes the subject unsuitable for inclusion. 2. Lactating women; women of childbearing potential with menstrual disorders within 90 days before dosing; women of childbearing potential who had unprotected intercourse with a male partner within 28 days before dosing. 3. Participation in any clinical trial of an investigational drug within 90 days before dosing, or still within the safety washout period of a previous trial on the day of dosing. 4. Non-physiological blood loss of ≥200 mL (including trauma, blood draw, blood donation) within 60 days before dosing, or plan to donate blood during the study or within 30 days after dosing. 5. Any major illness considered clinically significant by the investigator within 90 days before dosing. 6. Major surgery within 60 days before dosing, or any surgery within 28 days before dosing. 7. Fever or infectious illness within 28 days before dosing. 8. Use of any medication (including prescription, non-prescription, herbal, or dietary supplements) within 14 days before dosing. 9. Vaccination within 1 month before dosing, or plan to receive vaccination during the study period. 10. History or dependence of alcohol or drug abuse, or drug use, or a positive urine drug screen at screening. Alcohol abuse defined as average weekly intake \>21 standard alcohol units. One standard unit contains 14 g of alcohol (e.g., 360 mL of 5% beer, 45 mL of 40% spirits, or 120 mL of 12% wine). 11. Daily smoking of more than 5 cigarettes within 3 months before screening, or unable to refrain from smoking during the study. 12. Vital signs at screening meeting any of the following: systolic blood pressure \<90 mmHg or \>140 mmHg; diastolic blood pressure \<50 mmHg or \>90 mmHg; pulse rate \<50 beats/min or \>100 beats/min. 13. Positive test for hepatitis B surface antigen (HBsAg), hepatitis C virus antibody (HCV Ab), human immunodeficiency virus antibody (HIV Ab), or syphilis antibody. 14. Clinically evident gastrointestinal, hepatic, or renal abnormality that, in the investigator's opinion, may affect drug transport, absorption, distribution, metabolism, or excretion. 15. Any other condition that, in the investigator's judgment, might affect the study results or interfere with the subject's participation throughout the study, including but not limited to other medical history (e.g., psychiatric disorder), abnormalities in vital signs, physical examination, electrocardiogram, or clinical laboratory tests.
