ABC/DTG/3TC FDC

ViiV Healthcare · Phase 3 active Small molecule ✓ Verified May 2026

ABC/DTG/3TC FDC is a Antiretroviral combination therapy (NRTI + INSTI) Small molecule drug developed by ViiV Healthcare. It is currently in Phase 3 development for HIV-1 infection in treatment-naive and treatment-experienced adults.

A fixed-dose combination of three antiretroviral agents that inhibits HIV reverse transcriptase and integrase to suppress viral replication.

The ABC/DTG/3TC FDC is a fixed-dose combination of small molecule antiretroviral medications used to treat HIV-1 infection. It is a tablet formulation that can be used as a switch from an ongoing cART regimen, as studied in clinical trials such as NCT02105987.

Likelihood of approval
60.3% vs 58.3% industry baseline
If approved by FDA: likely 2028–2030

Confidence: High
Why this estimate
  • Baseline phase 3 → approval rate +58.3pp
    Industry-wide phase 3 drugs reach approval ~58.3% of the time (BIO/Informa 2023 industry benchmark across all therapeutic areas).
  • Anti-infectives pathway favourability +2.0pp
    Microbiological endpoints + non-inferiority designs raise approval rates above baseline.
Predicted approval windows by jurisdiction (conditional on FDA approval)

Mechanism of action

ABC (abacavir) is a nucleoside reverse transcriptase inhibitor (NRTI), DTG (dolutegravir) is an integrase strand transfer inhibitor (INSTI), and 3TC (lamivudine) is an NRTI. Together, they target two critical steps of HIV replication: reverse transcription of viral RNA and integration of viral DNA into the host genome, providing complementary mechanisms to suppress HIV-1 replication.
