Efficacy and Safety of the ACC017-Based Antiretroviral Regimen in Treatment-Experienced Adults With HIV-1 Harboring Non-Nucleoside Reverse Transcriptase Inhibitor Resistance Mutations

Participants will be excluded from this trial if they meet any of the following criteria:

1. The investigator judges that the participant has poor treatment compliance or protocol adherence, or any other condition that makes them unsuitable for participation, or that participation may not maximize the participant's health interests;

2. At screening, female participants are pregnant or breastfeeding, or male/female participants engaging in heterosexual activity plan to conceive (including sperm/egg donation) from 1 month before signing informed consent until 1 month after the last dose of the study drug, or are unable/unwilling to use effective contraception (including one or more non-pharmacological contraceptive methods or abstinence from heterosexual activity);

3. At screening or within 4 weeks before screening, participants are in the acute phase of HIV-1 infection or have concurrent opportunistic infections or other serious AIDS-defining conditions;

4. At screening or within 8 weeks before screening, resistance testing shows documented INSTI major resistance mutations, including but not limited to N155H and Q148H (as interpreted by the Stanford HIVdb database, including "low-level resistance \[L\]," "intermediate resistance \[I\]," and "high-level resistance \[H\]");

5. At screening, the investigator determines the presence of uncontrolled clinically significant diseases (including cardiovascular, respiratory, digestive, endocrine/metabolic, neuropsychiatric, hematologic, or immune system disorders), such as resting systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg, NYHA Class III or IV heart failure, etc.;

6. At screening, ALT \>5× upper limit of normal (ULN), or ALT \>3×ULN with total bilirubin (TBIL) \>1.5×ULN or direct bilirubin (DBIL) \>ULN, or other laboratory abnormalities graded ≥3 per CTCAE v5.0;

7. At screening, creatinine clearance \<50 mL/min (calculated by Cockcroft-Gault formula);

8. At screening, concurrent active hepatitis B virus (HBV) and/or hepatitis C virus (HCV) infection; or active syphilis infection requiring or having completed syphilis treatment \<7 days prior (as judged by the investigator);

9. Before screening, underwent major gastrointestinal surgery (except uncomplicated appendectomy or cholecystectomy), or the investigator judges that elective surgery may be required during the trial;

10. Screening for the past 5 years, having suffered from malignant tumors (including cervical carcinoma in situ treated with cervical conization, or surgically cured basal cell carcinoma, squamous cell carcinoma, and/or carcinoma in situ \[excluding Bowen's disease\]);

11. Known history of allergy to the investigational drug, chemically similar drugs, or excipients; or a history of allergic diseases requiring medication control (such as asthma, urticaria, atopic dermatitis \[eczema\], etc.) prior to screening.

12. Within 5 years prior to screening, have a history of substance, alcohol, or other substance use disorders (excessive, inappropriate, or addictive use of substances, alcohol, or other substances for non-medical reasons, resulting in social, psychological, and physiological impairments).

13. Use of any prohibited medication as specified in the protocol within 14 days before the first dose of the investigational drug;

14. Before screening, intolerance to venipuncture, history of needle or blood phobia, or blood donation (including component donation) or significant blood loss (≥400 mL) or transfusion within 3 months before screening, or planned donation during the trial;

15. Within 3 months prior to screening, have participated in any interventional clinical trials, including but not limited to drugs, vaccines, or medical devices (referring to subjects who have signed the informed consent form and received the investigational drug/device or placebo).
