1)The ability to understand and sign a written informed consent form,
which must be obtained prior to initiation of study procedures.
2) Age = 18 years
3)Antiretroviral treatment naïve (= 10 days of prior therapy with any antiretroviral agent following a diagnosis of HIV-1 infection) except the
use for PrEP (pre-exposure prophylaxis) or PEP (post-exposure prophylaxis), up to one month prior to screening.
4)Plasma HIV-1 RNA levels ? 500 copies/mL at screening.
5)Adequate renal function: Estimated glomerular filtration rate = 50 mL/min (= 0.83 mL/sec) according to the Cockcroft-Gault formula.
6)Hepatic transaminases (AST and ALT) ?5 x upper limit of normal (ULN).
7)Total bilirubin ?1.5 mg/dL (?26 umol/L), or normal direct bilirubin.
8) Adequate hematologic function (absolute neutrophil count = 750/mm3 (= 0.75 GI/L), platelets = 50,000/mm3 (= 50 GI/L);
hemoglobin = 8.5 g/dL (= 85 g/L).
9) Serum amylase = 5 × ULN (subjects with serum amylase > 5 × ULN will remain eligible if serum lipase is = 5 × ULN)
10) Females of childbearing potential must agree to utilize protocol recommended highly effective contraceptive methods or be non-sexually
active from screening, throughout the duration of the study period, and for 30 days following the last dose of study drug.
11) Male subjects who engage in heterosexual intercourse must agree to use protocol specified method(s) of contraception throughout the
study period and for 90 days following the last dose of study drug.
12) Life expectancy = 1 year
13) Negative screening test for HLA-B*5701 allele from a local
laboratory.
Are the trial subjects under 18? no
Number of subjects for this age range:
F.1.2 Adults (18-64 years) yes

F.1.3.1 Number of subjects for this age range
1)An opportunistic illness indicative of stage 3 HIV diagnosed within the 30 days prior to screening.
2) Subjects experiencing decompensated cirrhosis (e.g, ascites, encephalopathy, or variceal bleeding).
3) Have been treated with immunosuppressant therapies or chemotherapeutic agents within 3 months of study screening, or
expected to receive these agents or systemic steroids during the study (e.g, corticosteroids, immunoglobulins, and other immune- or cytokinebased
therapies).
4) A history of or ongoing malignancy (including untreated carcinoma in-situ) other than cutaneous Kaposi's sarcoma (KS), basal cell
carcinoma, or resected, non-invasive cutaneous squamous carcinoma.
5)Any anticipated to require systemic therapy during the study.
6) Active, serious infections (other than HIV-1 infection) requiring parenteral antibiotic or antifungal therapy within 30 days prior to Day 1.
7)Participation in any other clinical trial, including observational studies, without prior approval from the sponsor is prohibited while
participating in this trial.
8)Any other clinical condition or prior therapy that, in the opinion of the Investigator, would make the subject unsuitable for the study or
unable to comply with the dosing requirements.
9)Any known allergies to the excipients of D/C/F/TAF FDC or ABC/DTG/3TC FDC tablets.
10) Females who are pregnant (as confirmed by positive serum pregnancy test at screening).
11) Females who are breastfeeding.
12) Subjects receiving ongoing therapy with any significant interaction with the study drugs, including drugs not to be used with FTC, TAF, D, C
DTG, ABC and 3TC.
13) Chronic Hepatitis B Virus (HBV) infection.
14) Active tuberculosis infection.
