Doravirine for Persons With Excessive Weight Gain on Integrase Inhibitors and Tenofovir Alafenamide
a study on HIV/AIDS
The primary purpose of this study is to see if people with HIV who had a significant weight gain after starting INSTI (integrase strand transfer inhibitor)+TAF/FTC (tenofovir alafenamide/emtricitabine) (TAF/3TC (lamivudine)) regimen could either slow their rate of weight gain or lose weight within about 1 year if they switch to a regimen containing doravirine (DOR; a newer, non-nucleoside reverse transcriptase inhibitor medication). The study will also try to see if participants changing from TAF/FTC (or TAF/3TC) to TDF/FTC (or TDF/3TC) will experience less additional weight gain or a reduction in overall body weight at 48 weeks compared to persons continued on an INSTI + TAF/FTC (or TAF/3TC) combination. INSTINs assessed in A5391 include bictegravir (BIC), dolutegravir (DTG), or raltegravir (RAL). Additionally, the study will see whether a change in ART can affect things like waist circumference, metabolic and cardiovascular health, fat and lean mass body composition, bone health, and maintenance of virologic suppression. Finally, the study will look at the safety and tolerability of DOR plus either TAF/FTC (or TAF/3TC) versus TDF/FTC (or TDF/3TC).

Open to people ages 18 years and up
- Ability and willingness of participant or legal guardian/representative to provide informed consent.
HIV-1, documented by any licensed rapid HIV test or HIV enzyme or chemiluminescence immunoassay (E/CIA) test kit at any time prior to study entry and confirmed by a licensed Western blot or a second antibody test by a method other than the initial rapid HIV and/or E/CIA, or by HIV-1 antigen, or plasma HIV-1 RNA viral load. If a rapid HIV test or any FDA-approved HIV-1 E/CIA test kit is not available, two HIV-1 RNA values ≥2000 copies/mL at least 24 hours apart may be performed by any US laboratory that has a Clinical Laboratory Improvement Amendments (CLIA) certification or its equivalent, or by any non-US laboratory that is DAIDS Good Clinical Laboratory Practice (GCLP) compliant and, if performing HIV-1 RNA testing, is Virology Quality Assurance (VQA)-certified.
NOTE: The term "licensed" refers to a US FDA-approved kit, or for sites located in countries other than the United States, a kit that has been certified or licensed by an oversight body within that country and validated internally. World Health Organization (WHO) and CDC (Centers for Disease Control and Prevention) guidelines mandate that confirmation of the initial test result must use a test that is different from the one used for the initial assessment. A reactive initial rapid test should be confirmed by either another type of rapid assay or an E/CIA that is based on a different antigen preparation and/or different test principle (e.g., indirect versus competitive), or a Western blot or a plasma HIV-1 RNA viral load.
Currently, on a BIC (bictegravir), DTG (dolutegravir), or RAL (raltegravir) +TAF/FTC (or TAF/3TC) regimen with ≥48 weeks INSTI+TAF/FTC (or TAF/3TC) dosing prior to study entry.
NOTE A: Participants who did not start TAF at the same time as they started an INSTI will be eligible if they started TAF/FTC (or TAF/3TC) ≥48 weeks prior to study entry. NOTE B: Participants who underwent within-INSTI class substitutions (including from EVG (elvitegravir) to BIC, DTG, or RAL) will be eligible if substitution occurred ≥24 weeks prior to study entry. NOTE C: Participants are permitted ART adherence gaps of ≤7 days (i.e., missed doses), with a maximum of 3 gaps in the 48 weeks prior to study entry.
- Ability to acquire NRTIs (TAF/FTC or TAF/3TC, and TDF/FTC or TDF/3TC) and INSTI through usual care for the duration of the study.
- A BMI ≥27.5 kg/m2 at screening.
- An unintentional >10% weight gain in the 1-3 years after initiating or switching to INSTI-based ART and with ≥48 weeks of TAF/FTC (or TAF/3TC) preceding enrollment, as ascertained from clinical records, with no other medically apparent reason to readily explain the weight gain (including, but not limited to, concomitant medication use [e.g., corticosteroids], Cushing's disease, recent prolonged hospitalization, etc.), in the opinion of the site investigator.
- No known plans to change or to initiate medications known to be associated with significant weight changes during study period.
- Agree to adhere to assigned ART during the study period
- At least one HIV-1 RNA level <50 copies/mL (or below the lower limit of HIV-1 RNA detection available at the site if the lower limit of detection is >50) performed in the 48 weeks prior (≤48 weeks) to study screening, and at least one HIV-1 RNA level <50 copies/mL ≥48 weeks prior to study screening, using an FDA-approved assay performed by any US laboratory that has a CLIA certification or its equivalent, or at any network-approved non-US laboratory that is VQA certified. HIV-1 RNA values prior to the screening visit will be assessed for eligibility by the site and assay dates and values do not need to be entered on an eCRF.
- Screening HIV-1 RNA <50 copies/mL (or below the lower limit of HIV-1 RNA detection available if the lower limit of detection is >50) performed within 45 days prior to study entry by any US laboratory that possesses a CLIA certification or its equivalent, or at any network-approved non-US laboratory that is VQA certified.
For participants capable of becoming pregnant, negative serum or urine pregnancy test within 45 days prior to study entry by any US clinic or laboratory that has a CLIA certification or its equivalent, or is using a point of care (POC)/ CLIA-waived test, or at any network-approved non-US laboratory or clinic that operates in accordance with GCLP and participates in appropriate external quality assurance programs.
NOTE: Participants capable of becoming pregnant are defined as individuals who were assigned a female sex at birth and of reproductive potential; (i.e., have reached menarche and who have not been post-menopausal for at least 24 consecutive months, and have not undergone surgical sterilization such as hysterectomy, bilateral oophorectomy, tubal ligation, or salpingectomy). This includes transgender men who could become pregnant if menstruation were not suppressed. Participant-reported history is acceptable documentation of menopause.
- Participants engaging in sexual activity and capable of becoming pregnant must agree to use contraception while on study drug (approximately 48 weeks) and for 8 weeks after the end of the study. At least one of the following contraceptive methods must be used:
- Intrauterine device (IUD)
- Hormone-based contraceptive
Partner sterilization (i.e., vasectomy) and is the sole partner for the participant.
NOTE: Participant report of partner sterilization is acceptable.
Transgender participants who are currently taking hormones must be on a stable hormone dose for >12 weeks prior to study entry. Transgender participants should not have active plans to change their hormone regimen or dose during the study period.
NOTE: As some transgender participants may also use hormones purchased outside of the medical system (e.g., street hormones), the medication history should include questions about the use of these agents.
- The following laboratory values obtained within 45 days prior to study entry by any US laboratory that has a CLIA certification or its equivalent, or at any network-approved non-US laboratory that operates in accordance with GCLP and participates in appropriate external quality assurance programs:
- Absolute neutrophil count (ANC) >750 cells/mm3
- Hemoglobin >10 g/dL for males and >9 g/dL for females (based on sex at birth)
- Calculated creatinine clearance ≥50 mL/min as estimated by the CKD-EPI equation (a calculator is available at: https://qxmd.com/calculate/calculator_251/egfr-using-ckd-epi)
- Aspartate aminotransferase (AST) (SGOT) <3x ULN
- Alanine aminotransferase (ALT) (SGPT) <3x ULN
