Efficacy of 2-monthly VOCABRIA + REKAMBYS has been investigated in multiple clinical trials, including SOLAR, CARES and ATLAS-2M*[13]

Discover SOLAR:

A head-to-head switch study comparing 2-monthly VOCABRIA + REKAMBYS with regular daily oral therapy with BIC/FTC/TAF.[1]

  • View key outcomes from SOLAR

    Non-inferior efficacy, with less frequent dosing vs regular daily oral therapy.

    For people living with HIV, confidence in treatment efficacy is important.[7,8]

    Data from the SOLAR trial confirmed that 2-monthly VOCABRIA + REKAMBYS was non-inferior to regular daily oral therapy with BIC/FTC/TAF.[1]

    The SOLAR primary endpoint was met: 2-monthly VOCABRIA + REKAMBYS was non-inferior to BIC/FTC/TAF at Month 12 (mITT-E: 1% [n=5/447] with plasma HIV-1 RNA ≥50 copies/mL vs 0.4% [n=1/223], respectively; adjusted difference = 0.7% [95% CI: -0.7%, 2.0%]; 4% non-inferiority margin).[1]

    *12% non-inferiority margin.[1]

Discover CARES:

A 96-week phase IIIb study comparing VOCABRIA + REKAMBYS with regular daily oral therapy in sub-Saharan Africa.[2]

  • View key outcomes from CARES

    Sustained efficacy, in diverse populations.

    Advancing HIV care means offering an effective treatment option that meets specific needs of people living with HIV.[7,8] The CARES clinical trial explored the efficacy of 2-monthly VOCABRIA + REKAMBYS in a population comprising a majority of Black, female and NNRTI-treatment experienced people living with HIV in Uganda, Kenya and South Africa.[2]

    The CARES primary endpoint was met: 2-monthly VOCABRIA + REKAMBYS was non-inferior to daily oral therapy at Week 48 (ITT-E: 96% [n=246/255] with plasma HIV-1 RNA <50 copies/mL vs 97% [n=250/257], respectively; adjusted difference = -0.8% [95% CI: -3.7%, 2.3%]; -10% non-inferiority margin).[9]

    *Participants in the daily oral therapy arm received once daily TDF + 3TC or FTC + DTG, NVP or EFV.[2]
†-10% non-inferiority margin.[2]

Discover ATLAS-2M*:

A large, phase IIIb, open-label, non-inferiority study investigating the efficacy, safety, and durability of VOCABRIA + REKAMBYS over 3 years.[3]

  • View key outcomes from ATLAS-2M

    Demonstrated durability, backed by 3-year data.

    For those navigating long-term HIV management, reliable, sustained efficacy is important.[8,10]

    87% of participants remained on and were virologically suppressed with 2-monthly VOCABRIA + REKAMBYS after 3 years in ATLAS-2M**[3]

    The ATLAS-2M primary endpoint was met: 2-monthly VOCABRIA + REKAMBYS was virologically (plasma HIV-1 RNA ≥50 copies/mL) non-inferior to monthly VOCABRIA + REKAMBYS at Week 48 (1.7% vs 1.0%, respectively).[3]

    *QM CABOTEGRAVIR + RILPIVIRINE is not available in the UK.

    **At the Week 152 data cutoff, 87% (n=452/522) of participants remained in the 2-monthly VOCABRIA + REKAMBYS arm; 13% (n=70/522) of participants discontinued the study of which 12% (n=65/522) were due to treatment withdrawal. The most common reason for treatment withdrawal in the 2-monthly arm was AEs (4% [n=23/522]).[3]

Effectiveness of VOCABRIA + REKAMBYS was investigated in multiple studies of real-world cohorts, including: OPERA, COMBINE-2 C2C and RELATIVITY[46]

Discover OPERA:

A real-world cohort study assessing the effectiveness of VOCABRIA + REKAMBYS, across the US.[4]

  • View key outcomes from OPERA cohort

    High effectiveness, large US cohort.

    This large observational study demonstrates high effectiveness consistent with clinical trials, in the diverse, routine settings of the US.[4]

Discover COMBINE-2 C2C:

A real-world utilisation and effectiveness study of VOCABRIA + REKAMBYS.[5]

  • View key outcomes from COMBINE-2 C2C cohort

    High effectiveness, in a pan-European study.

    Extending the real-world evidence base, the COMBINE-2 C2C study demonstrated consistent effectiveness at Month 6, Month 12 and Month 24, within the diverse patient populations and clinical practices in Europe.[5]

Discover RELATIVITY:

A real-world cohort study of the effectiveness of VOCABRIA + REKAMBYS across diverse Spanish population.[6]

  • View key outcomes from RELATIVITY cohort

    Consistent effectiveness demonstrated over 13 months.

    The RELATIVITY study demonstrated that VOCABRIA + REKAMBYS was effective across a diverse real-world population of people living with HIV in Spain, showing effectiveness for a wide range of individuals with varying characteristics and lived experiences.[6]

    RELATIVITY primary endpoint was treatment effectiveness, defined as the proportion of patients discontinuing LAI therapy for any reason, including loss of virological suppression (HIV-RNA >50 copies/mL) during follow-up, regardless of formal failure criteria.
