HIV-1-infection
Conditions
Brief summary
This is an open-label, single arm, single-centre prospective study to evaluate the feasibility, efficacy and safety of a once daily fixed dose combination regimen, Biktarvy, as a rapid treatment strategy in newly HIV diagnosed patients that come for the first time to the Hospital Clínic HIV Unit Patients with confirmed HIV-1 diagnosis who wish to start ARV treatment immediately will receive bictegravir 50 mg + emtricitabine 200 mg + tenofovir alafenamide 25 mg within the first week since the HIV-1 confirmation during 48 weeks.

Inclusion criteria
1. Age ≥ 18 years old. 2. Having confirmed HIV-1 positive test. 3. Patients not previously treated with antiretroviral treatment (post-exposure prophylaxis will be allowed if not done in the previous 6 months). 4. Clinically stable patients, in the opinion of the investigator, at the time of inclusion. 5. Women of child-bearing potential\* must have a negative pregnancy test in urine before the inclusion in the study and agree to use highly effective contraceptive methods during the study. Highly effective contraceptive methods will include: hormonal contraceptive methods intrauterine device, bilateral tubal occlusion, vasectomized partner or sexual abstinence. 6. Written informed consent.
Exclusion criteria
1. Pregnant or breastfeeding women at the time of the study inclusion or anticipating pregnancy during the follow-up period. 2. Suspicion of an active opportunistic infection that defers initiating antiretroviral treatment \> 7 days since HIV confirmation. 3. Known hypersensitivity or intolerance of any of the components of Biktarvy®. 4. Patients on treatment with any prohibited medication (see section 5.2: Concomitant, nonpermitted and permitted medication). 5. Any condition which, in the opinion of the principal investigator, may interfere with adequate understanding, cooperation or compliance with the study.

| Measure | Time frame | Description |
|---|---|---|
| Proportion of patients non-eligible to receive any of the antiretroviral regimens within the first week since the HIV confirmation) at week 4 | week 4 | Patients will be considered non-eligible if they meet one or more of the following creiteria at week 4: * Presence of HLA-B\* 5701 or lack of HLA test * Presence of HIV genotypic resistance mutations to at least one class of ARV drug that decrease efficacy of antiretroviral treatment * CD4 count \< 200 cells/mm3 * Viral load \> 100.000 copies/mL * Comorbidities such as: Osteopenia measured by DXA (T score less than 1), medical history of cardiovascular risk measured by Framingham risk score \> 10% at 10 years, Kidney function (eGFR \<50mL/min), * Concomitant medication that can cause potential interactions with ARV (evaluating the risk of drug-drug interactions for drugs no totally safe (green colour) using the Liverpool website for DDI) * Hepatitis B (HBV) coinfection or lack of serology |
