Preferences and Feasibility of Long-Acting Technologies for the Treatment of Hepatitis C Virus: A Survey of Patients in Diverse Low- and Middle-Income Countries.

Despite available curative treatments, global rates of hepatitis C virus (HCV) infection persist with significant burden in low- and middle-income countries (LMICs). Long-acting (LA) antiviral products are in development. This study explored the challenges and opportunities in LA-HCV treatment across three LMICs: Egypt, Ethiopia and India. The survey focused on understanding barriers and facilitators to treatment, with emphasis on LA treatment preferences. Four-hundred respondents completed a survey including demographics, HCV treatment history and preferences for injections, implants and microarray patches (MAPs) compared to pills. Overall, 78% of respondents were willing to receive injections, 43% were willing to receive implants and 55% were willing to receive MAPs. Marked heterogeneity in acceptability of non-oral treatments was observed. Among respondents who had not previously received HCV treatment, 94%, 43%, and 75% were willing to receive injections, implants, or MAPs, respectively. In contrast, among those already cured by oral HCV treatment, 61%, 40% and 43% were willing to receive injections, implants or MAPs. Other characteristics associated with willingness to receive an injection included urban residence, younger age, male sex, higher education level and taking pills for any reason (all results p < 0.001). The most common concern for all LA modalities was lack of effectiveness. Prior experience with injection or implant increased willingness to receive any LA modality (p < 0.001). Coupled with a point-of-care HCV diagnostic test, availability of and willingness to receive HCV treatment delivered by a LA formulation could simplify and expand treatment access in LMICs and contribute towards global HCV elimination goals.
