Inclusion Criteria: * HIV-1 infected, 18 years or older * On stable \& suppressive triple cART containing ABA/3TC or TAF/FTC plus dolutegravir or bictegravir for at least 6 months * No evidence of resistance to TDF, 3TC, or DOR * No laboratory abnormalities, medical/psychiatric conditions or alcohol/drug use considered a barrier to participation by investigators * Women who are of childbearing potential and sexually active need to use the hormonal contraceptive methods, associated with inhibition of ovulation, listed in the protocol: * Implant * Depot injection * Intra-uterine device or system * Oral hormonal contraception A woman is considered of childbearing potential (WOCBP), i.e. fertile, following menarche and until becoming post-menopausal unless permanently sterile. Permanent sterilisation methods include hysterectomy, bilateral salpingectomy and bilateral oophorectomy. A postmenopausal state is defined as no menses for 12 months without an alternative medical cause. A high follicle stimulating hormone (FSH) level in the postmenopausal range may be used to confirm a postmenopausal state in women not using hormonal contraception or hormonal replacement therapy. However in the absence of 12 months of amenorrhea, a single FSH measurement is insufficient. * Men who are sexually active and have partners who are women of childbearing potential must be using an adequate method of contraception to avoid pregnancy (male condom or sterilisation confirmed prior to the subject's entry into the study) Exclusion Criteria: * History of virological failure on an NNRTI in absence of a post-failure genotypic resistance test proving absence of resistance to DOR * Concomitant medication contra-indicated with TDF, FTC or DOR * Haemoglobin \<9 g/dL * Platelets \<80,000/mm3 * Creatinine clearance \<50 mL/min * AST or ALT ≥5N * Acute Hepatitis A infection. * Concomitant DAA for anti-HCV therapy * Known acute or chronic viral hepatitis B or C. o Individuals with positive anti-HCV results, but with HCV RNA not detected may be included on the trial. * Pregnant or breastfeeding women, or individuals actively trying to conceive * History of osteoporosis or bone fractures/loss * Hypersensitivity to the active substance or to any of the excipients in tenofovir disoproxil fumarate, lamivudine and/or doravirine formulations * Patients with rare hereditary problems of galactose intolerance, total lactase deficiency or glucose-galactose malabsorption.
