Real-World Experience with Coformulated Ledipasvir and Sofosbuvir for HIV-Positive Patients with HCV Genotype 2 Infection: A Multicenter, Retrospective Study

Introduction: While coformulated ledipasvir (90?mg)/sofosbuvir (400?mg) (LDV/SOF) is approved for the treatment of hepatitis C virus (HCV) genotype 2 (GT2) infection in Taiwan, Japan, and New Zealand, data regarding its use for HIV (Human Immunodeficiency Virus)-positive patients infected with HCV GT2 are sparse. We aimed to assess the effectiveness and tolerability of LDV/SOF for HIV-positive patients with HCV GT2 coinfection. Methods: From January 2019 to July 2020, consecutive HIV-positive Taiwanese patients infected with HCV GT2 who received LDV/SOF were retrospectively included for analysis. The effectiveness was determined by sustained virologic response 12?weeks off-therapy (SVR12). Results: Of the 114 patients (mean age, 38.6?years) initiating LDV/SOF during the study period, 0.9% had liver cirrhosis and 4.4% were HCV treatment-experienced. All patients had estimated glomerular filtration rate (eGFR)?>?30?ml/min/1.73?m2 and were receiving antiretroviral therapy with 98.2% having CD4 counts???200 cells/mm3 and 93.9% plasma HIV RNA load?<?50 copies/ml. Antiretrovirals prescribed included tenofovir alafenamide/emtricitabine in 42.1%, tenofovir disoproxil fumarate (TDF)/emtricitabine 18.4%, other nucleoside reverse transcriptase inhibitors (NRTIs) 39.5%, non-NRTIs 12.3%, protease inhibitors 13.2%, and integrase inhibitors 74.6%. All patients had undetectable plasma HCV RNA load at the end of treatment, and 96.5% achieved SVR12 in intention-to-treat analysis. The on-treatment eGFR decline was more pronounced in those receiving TDF-containing antiretroviral therapy (mean change, ??8.33?ml/min/1.73?m2), which was reversible after discontinuation of LDV/SOF. None of the patients interrupted LDV/SOF during the 12-week treatment course. Conclusion: Similar to the response observed among HIV-negative patients, LDV/SOF is effective for HIV-positive patients coinfected with HCV GT2. ? 2021, The Author(s).
