Introduction The equity-focused Implementing Long-Acting Novel Antiretrovirals study evaluated feasibility, acceptability, appropriateness of delivering on-label 2-monthly cabotegravir and rilpivirine (CAB + RPV) injections for human immunodeficiency virus (HIV)-1 therapy in clinics and community settings. Methods The study, which mandated inclusive recruitment, was conducted May-December 2022 at 6 UK sites. Injections were delivered in clinic (month [M] 1-6) and in clinic or community setting according to patient choice (M6-12). Surveys were completed at baseline, M4, and M12 using validated measures for feasibility (FIM), acceptability (AIM), and appropriateness (IAM). Primary endpoint: proportion of participants agreeing that the injection and community setting were feasible (FIM ≥4) at M12. Fourteen participants completed interviews at baseline and M12. Results Community settings offered by sites included: home visits (n = 3), HIV support organizations (n = 2), and community clinic (n = 1). Of 114 participants, 54% were female, 70% racially minoritized, and 40% aged ≥50 years. A total of 27/114 chose to receive injections in community settings. FIM/AIM/IAM scores at M12 were high for the injection (79.0-87.4%) and lower for the community setting (44.2-47.4%) overall. Subgroup analyses indicated differences in scores by gender and ethnicity. Among those who attended the community, FIM/AIM/IAM scores for the community setting at M12 were high (73.1-80.8%). Concerns about stigma, inconvenience, and losing access to trusted clinicians negatively influenced perceptions of receiving injections at community settings, amongst other factors. Conclusions CAB + RPV injections were considered highly feasible, acceptable, and appropriate; however, few chose community delivery. Those that chose community delivery found it highly acceptable and feasible. Further exploration of CAB + RPV delivery in alternative community sites not offered (eg, primary care, pharmacies) is warranted.
