Abstract

Adherence challenges with oral pre-exposure prophylaxis have stimulated interest in alternate modes of administration including long-acting injections. We conducted 30 in-depth interviews with 26 male trial participants and 4 clinical providers in a Phase IIa study (ÉCLAIR) evaluating the use of long-acting cabotegravir (CAB-LA) injections in New York and San Francisco. Interviews exploring attitudes and experiences with CAB-LA were audiotaped, transcribed, and analyzed using thematic content analysis. Despite a high frequency of some level of side effects, almost all participants reported being interested in continuing with CAB-LA, versus a daily oral, due to its convenience and the perceived advantage of not worrying about adhering to pills. Providers reinforced the importance of CAB-LA as a prevention option and the need for guidelines to assist patient decision-making. Further research is needed on the acceptability of CAB-LA among men and women at higher risk for HIV in different settings.

Resumen

Los retos de adherencia con la profilaxis oral previa a la exposición (PrEP, por sus siglas en inglés) han estimulado el interés en modos alternos de administración incluyendo inyecciones de acción prolongada. Realizamos 30 entrevistas en profundidad con 26 participantes masculinos del ensayo y 4 proveedores clínicos en un estudio de Fase IIa (ÉCLAIR) que evaluó el uso de inyecciones de acción prolongada de cabotegravir (CAB-LA) en Nueva York y San Francisco. Las entrevistas que exploran actitudes y experiencias con CAB-LA fueron grabadas, transcritas y analizadas usando análisis de contenido temático. A pesar de una alta frecuencia de algún nivel de efectos secundarios, casi todos los participantes informaron estar interesados en continuar con CAB-LA, frente a una pastilla diaria, debido a su conveniencia y la ventaja percibida de no preocuparse por adherirse a las pastillas. Los proveedores reforzaron la importancia de CAB-LA como una opción de prevención y la necesidad de directrices para ayudar a los pacientes en la toma de decisiones. Se necesita más investigación sobre la aceptabilidad de CAB-LA entre hombres y mujeres con mayor riesgo de VIH en diferentes contextos.
