AI summary: who the study is looking for

From the trial's eligibility criteria. Machine-read from the registry text on this page, so it can be wrong. The registry text below and the trial team decide who can take part.

The trial is looking for adults living with HIV-1 whose virus is well controlled on Biktarvy. It compares a once-weekly pill regimen with daily Biktarvy.

Age
18 years or older
Sex
All sexes can join.
Disease stage
HIV-1 with virus level under control: plasma HIV-1 RNA below 50 copies/mL for at least 24 weeks before and at screening.
Earlier treatment
Must have taken Biktarvy for at least 24 weeks before screening. Cannot have used lenacapavir, GS-1720 or GS-4182 before. Cannot have used long-acting injectable HIV drugs, antibodies against HIV-1, or injectable cabotegravir or rilpivirine.
Biomarker or test result
No known resistance to integrase inhibitors. CD4 count at least 200 cells/mm3. No detectable hepatitis C virus RNA.

Main reasons for not taking part

  • Active or hidden hepatitis B infection
  • Active hepatitis C or active tuberculosis
  • Past treatment failure on an integrase inhibitor regimen

An Operationally Seamless Phase 2/3, Randomized, Active -Controlled Study Evaluating the Safety and Efficacy of an Oral Weekly Regimen of GS-1720 in Combination With GS-4182 Versus Biktarvy in Virologically Suppressed People With HIV-1

Phase 2: To evaluate the efficacy of switching to oral weekly GS-1720 in combination with GS-4182 versus continuing bictegravir/emtricitabine/tenofovir alafenamide (BVY; coformulated, Biktarvy®) in virologically suppressed PWH at Week 24 Phase 3: To evaluate the efficacy of switching to oral weekly GS-1720/GS-4182 fixed-dose combination (FDC) tablet regimen versus continuing BVY in virologically suppressed PWH at Week 48

Inclusion: Participants must meet all of the following inclusion criteria to be eligible for participation in this study: Participants 18 years of age or older and able to understand and give written informed consent; Participants assigned male at birth and participants assigned female at birth and of childbearing potential who engage in heterosexual intercourse must agree to use protocol-specified methods of contraception; Documented plasma HIV-1 RNA < 50 copies/mL for ≥ 24 weeks before and at screening; Receiving BVY for ≥ 24 weeks prior to screening.

Exclusion: Participants who meet any of the following exclusion criteria are not eligible to be enrolled in this study: Prior use of, or exposure to LEN, GS-1720, or GS-4182; Have been treated within 6 months of study screening or expected to receive during the study immunosuppressant therapies or chemotherapeutic agents (eg, chronic [at least 4 weeks] systemic steroids, immunoglobulins, and other immune- or cytokine-based therapies); Participation in any other clinical study, including observational studies, without prior approval from the Sponsor is prohibited while participating in this study; Participants with plans to breastfeed during the study period and within 60 days following the last dose of study drug; Serious illness requiring hospitalizations within 30 days prior to screening and during the screening period or active malignancy requiring acute systemic treatment; Requirement for ongoing therapy with or prior use of any prohibited medications; Any other clinical condition or prior therapy that, in the opinion of the investigator, would make the participant unsuitable for the study or unable to comply with the dosing requirements, including medical history of psychotic disorder and/or use of antipsychotic medications prescribed for psychosis; Prior use of any Long Acting (LA) parenteral antiretrovirals (ARVs) such as monoclonal antibodies (mAbs) or broadly neutralizing antibodies (bNAbs) targeting HIV-1, injectable cabotegravir (including oral cabotegravir lead-in), or injectable rilpivirine; Active hepatitis C virus (HCV) defined as detectable HCV RNA. Note: Participants with prior/inactive HCV infection (defined as undetectable HCV RNA) may enroll; Known hypersensitivity to the study drug, its metabolites, or formulation excipient; History of virologic failure while on an integrase strand-transfer inhibitor (INSTI)-based regimen; Active tuberculosis infection; Active or occult hepatitis B virus (HBV) infection as defined below (regardless of other HBV serologic results).
