Although there are currently effective treatment options for HBV, treatment-resistant variants and the need for lifelong therapy pose a significant challenge. Therefore, the development of new treatment options is crucial to improve out-comes and quality of life. Herein, this study reports preclinical evidence showing that the anti-HBV agent, E-CFCP, has potent activity against wild-type and treatment-resistant variants. In addition, once-weekly oral dosing may be possible,which is preferable to the current daily dosing regimens.

    Efficacy and safety of long-acting (LA) cabotegravir (CAB) and rilpivirine (RPV) dosed intramuscularly every 4 or 8 weeks has been demonstrated in three Phase 3 trials. Here, factors associated with virologic failure at Week 48 were evaluated post hoc.

      Phase 3 clinical studies showed non-inferiority of long-acting intramuscular cabotegravir and rilpivirine dosed every 4 weeks to oral antiretroviral therapy. Important phase 2 results of every 8 weeks dosing, and supportive modelling, underpin further evaluation of every 8 weeks dosing in this trial, which has the potential to offer greater convenience. Our objective was to compare the week 48 antiviral efficacy of cabotegravir plus rilpivirine long-acting dosed every 8 weeks with that of every 4 weeks dosing.

          This study assessed whether switching to monthly injections of long-acting cabotegravir plus rilpivirine would be noninferior to continuing oral therapy in patients with HIV type 1 (HIV-1) who had viral suppression in response to oral induction therapy.

                Safe and efficacious medicines are available for the prevention and treatment of major diseases, but their effectiveness can be compromised by poor treatment completion. Lack of adherence can worsen clinical outcomes, leading to increased mortality, persistent transmission and increased drug resistance in the case of antimicrobials and antivirals. Analyses of treatment and prevention of HIV, malaria, and TB within public health programs show wide disparities in rates of completion, especially among specific populations and regions.
