Efficacy and Freedom: Patient Experiences with the Transition from Daily Oral to Long-Acting Injectable Antiretroviral Therapy to Treat HIV in the Context of Phase 3 Trials

Engagement in Care, Awareness, and Interest in Long-Acting Injectable Anti-Retroviral Therapy

Long Acting Injectable (LAI) therapy to treat HIV is an alternative to daily oral medications. The success of early roll-out of LAI to eligible patients requires a better understanding of patients' awareness and interest in this novel therapy. We administered an electronic survey to patients attending an urban HIV clinic in the US South. Eligible participants were 18 + years old with a most recent HIV-1 viral load < 200 copies/ml, without any evidence of genotypic resistance to LAI components or chronic hepatitis B. Survey recipients were asked about current treatment, engagement in care, and knowledge of LAI. Between January-April 2023, 480 patients were screened; 319 were eligible, and 155 (49%) completed the survey. The majority (119, 77%) were aware of, and 87 (56%) were interested in LAI. In regression analysis, only age was associated with interest in LAI (OR 0.95, 95% CI 0.92,0.99). Among proposed benefits of injectables, ease of travel without pills, lack of daily pill-taking, and fewer medication interactions were most appealing. Among proposed concerns with injectables, higher cost and insurance coverage of the new medicine were most worrisome. A large majority of people with HIV (PWH) are aware of the newest treatment available, and just over half of our sample expressed interest in LAI. Older age was associated with lower interest in LAI. LAI is appealing for its convenience, privacy, and avoidance of drug interactions, while the increased costs associated with LAI need to be addressed.

Implementing long-acting injectable antiretroviral treatments in Senegal: issues, challenges and conditions for introducing them. Qualitative study with healthcare providers and patients

Long-acting injectable antiretroviral therapy (LAI-ART) can offer people living with HIV (PLWH) a promising alternative to daily oral therapy. This article highlights the issues, challenges and conditions related to introducing LAI-ART into the social lives of PLWH and HIV-care practices in Senegal. Semi-structured interviews were conducted with 42 PLWH in two hospital care units in Dakar and with 13 healthcare providers and 6 peer educators. Interviews were transcribed, thematically coded and analysed using a cross-sectional approach. We found three key issues. First, simplifying living with HIV: PLWH respondents perceive LAI-ART as an opportunity to ease the burden associated with taking tablets. This enthusiasm may however be qualified by an ambivalent relationship with injections and is subject to certain conditions. Second, certain constraints linked to the medicalisation of care are to be anticipated, including the obligation to go to the hospital every two months for injections. These findings foreshadow the new management work for medical follow-up expected to fall on PLWH and caregivers. Third, the challenges of introducing LAI-ART in Senegal are to ensure adequate organisation of care and supply and sustainability of the program. These results clarify how to implement programs to introduce LAI-ART into real life in the West African context.

Patient Education and Decision Support for Long-Acting Injectable HIV Antiretroviral Therapy: Protocol for Tool Development and Pilot Testing with Ryan White HIV/AIDS Program Medical Case Management Programs in New York

BACKGROUND

Long-acting injectable (LAI) HIV antiretroviral therapy (ART) presents a major opportunity to facilitate and sustain HIV viral suppression, thus improving health and survival among people living with HIV and reducing the risk of onward transmission. However, realizing the public health potential of LAI ART requires reaching patients who face barriers to daily oral ART adherence and thus can clinically benefit from alternative treatment modalities. Ryan White HIV/AIDS Program Part A medical case management (MCM) programs provide an array of services to address barriers to HIV care and treatment among economically and socially marginalized people living with HIV. These programs have demonstrated effectiveness in improving engagement along the continuum of care, but findings of limited program impact on durable viral suppression highlight the need to further innovate and hone strategies to support long-term ART adherence.

OBJECTIVE

This study aims to adapt and expand Ryan White MCM service strategies to integrate LAI ART regimen options, with the larger goal of improving health outcomes in the populations that could most benefit from alternatives to daily oral ART regimens.

METHODS

In 3 phases of work involving patient and provider participants, this study uses role-specific focus groups to elicit perceptions of LAI versus daily oral ART; discrete choice experiment (DCE) surveys to quantify preferences for different ART delivery options and related supports; and a nonrandomized trial to assess the implementation and utility of newly developed tools at 6 partnering Ryan White HIV/AIDS Program Part A MCM programs based in urban, suburban, and semirural areas of New York. Findings from the focus groups and DCEs, as well as feedback from advisory board meetings, informed the design and selection of the tools: a patient-facing, 2-page fact sheet, including frequently asked questions and a side-by-side comparison of LAI with daily oral ART; a patient-facing informational video available on YouTube (Google Inc); and a patient-provider decision aid. Implementation outcomes, measured through provider interviews, surveys, and service reporting, will guide further specification of strategies to integrate LAI ART options into MCM program workflows.

RESULTS

The study was funded in late April 2021 and received approval from the institutional review board in May 2021 under protocol 20-096. Focus groups were conducted in late 2021 (n=21), DCEs ran from June 2022 to January 2023 (n=378), and tools for piloting were developed by May 2023. The trial (May 2023 through January 2024) has enrolled >200 patients.

CONCLUSIONS

This study is designed to provide evidence regarding the acceptability, feasibility, appropriateness, and utility of a package of patient-oriented tools for comparing and deciding between LAI ART and daily oral ART options. Study strengths include formative work to guide tool development, a mixed methods approach, and the testing of tools in real-world safety-net service settings.

"This Is Actually a Really Unique Moment in Time": Navigating Long-Acting HIV Treatment and HIV Cure Research with Analytical Treatment Interruptions-A Qualitative Interview Study in the United States

Advancements in long-acting (LA) HIV treatment and cure research with analytical treatment interruptions (ATIs) have generated important scientific and implementation questions. There is an urgent need to examine challenges navigating the evolving HIV treatment and cure research landscape. From August to October 2022, we conducted 26 semistructured interviews with biomedical researchers and community members representing a predominantly woman demographic to explore the complexity of navigating the rapidly evolving HIV therapeutic and HIV cure research landscape. We purposively sampled individuals recruited from the AIDS Clinical Trials Group and the Martin Delaney Collaboratories for HIV Cure Research. Audio files were transcribed verbatim and analyzed through a thematic approach, using an inductive and iterative process. Among 26 participants, 10 were biomedical researchers and 16 community members, including 11 were people with HIV. Three main themes emerged: (1) We are at a pivotal moment in the evolving landscape of HIV therapeutics and LA HIV treatment and HIV cure research should not be siloed but considered together; (2) There are challenges with engagement in HIV cure research and in switching between oral daily antiretroviral treatment and LA formulations and, mainly, the prolonged pharmacokinetic tail of these compounds matched with limited patient education about their impacts; and (3) There are unique opportunities as a result of this evolving therapeutic landscape, including the key role of decision support for people with HIV, centering around patient autonomy, and the need to learn from the lived experiences of people with HIV who choose LA treatment and/or participation in HIV cure research. Despite a bias toward the woman gender, our study identifies key considerations for navigating concurrent LA HIV treatment and HIV cure research with ATIs from both community members and biomedical researchers' perspectives. Achieving optimal HIV control remains a formidable challenge, necessitating robust interdisciplinary collaborations and engagement with key stakeholders.

Preference for long-acting injectable for ART and PrEP among people with and without HIV: a cross-sectional study in Argentina

Background

Little is known about the preferences for antiretroviral therapy (ART) administration methods, such as oral daily pills or long-acting injectable (LAI) options, as well as preferences for pre-exposure prophylaxis (PrEP) administration methods among people without HIV in Latin America.

Objectives

This study aimed to assess the preferences for ART administration methods among people with HIV and PrEP methods among those without HIV, as well as to examine the correlations and reasons for these preferences.

Design

We conducted a cross-sectional web-based questionnaire between April and July 2021, using social media accounts of a HIV non-governmental organization. The questionnaire was open to all adults living in Argentina, irrespective of their sexual orientation or gender identity.

Methods

The questionnaire included questions on substance use, depression, chronic treatment, previous experiences with injectable medication, and HIV status. Those with HIV answered questions about ART adherence and their preferences for ART methods, while those without HIV were asked about condom use, awareness of PrEP, and their preferences for PrEP methods.

Results

Out of 1676 respondents, 804 had HIV, and 872 did not. Among those with HIV, 91.5% expressed a high preference for LAI-ART, with significantly higher preferences among participants with higher educational levels, cisgender gay, bisexual, and queer men, younger individuals, and those with prior injectable medication experience. Among those without HIV, 68% preferred LAI-PrEP, and this preference was positively associated with previous positive experiences with injectable medication.

Conclusion

The strong preference for LAI-ART suggests the potential for improved adherence and well-being among people with HIV. Additionally, the preference for LAI-PrEP among those without HIV emphasizes the importance of considering this option for HIV prevention strategies. This study highlights the need to offer diverse methods for ART and prevention to accommodate different preferences and improve health care outcomes in Latin America.

Psychometric Validation of the Perception of Injection (PIN) Questionnaire Using Data From Two Phase III, Open-Label, Active-Controlled, Non-Inferiority Studies in People Living With HIV

INTRODUCTION

Currently, there are no patient-reported outcome tools specifically validated for use in people living with human immunodeficiency virus (PLHIV) to measure treatment injection acceptance and experience. The Perception of Injection (PIN) questionnaire was modified with consent from the Vaccinees' Perception of Injection (VAPI), a validated instrument developed by Sanofi Pasteur. The objective of developing the PIN was to provide information on participant experience with injectable therapies, including acceptance of pain, injection-site reactions, and tolerability following injections in PLHIV.

METHODS

This post hoc analysis used data from participants who received the long-acting intramuscular cabotegravir plus rilpivirine combination treatment every 4 weeks, as part of the ATLAS (NCT02951052) and FLAIR (NCT02938520) studies, to evaluate the psychometric properties of the PIN questionnaire.

RESULTS

These findings support the reliability, validity, and responsiveness to change for the PIN questionnaire in PLHIV.

CONCLUSION

As a clinical trial endpoint, the PIN questionnaire could provide valuable evidence around the acceptance and experience of injections in PLHIV which could have implications for treatment adherence in this population.

"What Is the Benefit?": Perceptions and Preferences for Long-Acting Injectable Antiretroviral Therapy Among People Living With HIV

Long-acting injectable antiretroviral therapy (LA-ART) expands treatment options for people living with HIV (PLWH). This qualitative study characterizes LA-ART awareness, perceptions, and preferences among PLWH engaged in HIV care. From 2019 through 2021, we conducted semistructured in-depth interviews with 71 PLWH sampled from three clinics in three U.S. settings (North Carolina, Washington, DC, Massachusetts). Transcripts were analyzed using narrative and thematic techniques. Participant mean age was 46 years (range 24-72); most were cisgender men (55%) and virally suppressed (73%). Most participants had not heard of LA-ART and reacted with a mix of excitement and cautiousness. Potential LA-ART benefits included easier adherence, privacy, and effectiveness; concerns included effectiveness, side effects, costs, and increased clinic visits. Participants appreciated that LA-ART could support achieving and sustaining viral suppression. To inform their decision, participants wanted more information and convenient access and administration. Findings indicated that a shared decision-making approach and economic and logistical support for PLWH could facilitate LA-ART uptake.

Acceptability, Feasibility, and Appropriateness of Implementation of Long-acting Injectable Antiretrovirals: A National Survey of Ryan White Clinics in the United States

Background

The approval of long-acting injectable cabotegravir/rilpivirine (LAI CAB/RPV) heightened the urgency of ensuring effective implementation. Our study assesses readiness and barriers to implement LAI CAB/RPV across Ryan White-funded clinics in the United States.

Methods

We conducted a cross-sectional survey between December 2020 and January 2021 using validated 4-item measures: acceptability of intervention measure (AIM), intervention appropriateness measure (IAM), and feasibility of intervention measure (FIM). Associations between measures and clinic characteristics were evaluated via Spearman rank correlations. A 5-point Likert scale ranked potential barriers of implementation responses. Open-ended questions were analyzed through a thematic approach.

Results

Of 270 clinics, 44 (16%) completed the survey: 38% federally qualified health centers, 36% academic, 20% community-based organizations, 14% hospital outpatient, and 9% nonprofit. Means (SD; range) were as follows: AIM, 17.6 (2.4; 12-20); IAM, 17.6 (2.4; 13-20); and FIM, 16.8 (2.9; 7-20). Twenty percent were not at all ready to implement LAI CAB/RPV, and 52% were slightly or somewhat ready. There was a significant association between AIM and the proportion of Medicaid patients (AIM, rho = 0.312, P = .050). Community-based organizations scored the highest readiness measures (mean [SD]: AIM, 19.50 [1.41]; IAM, 19.25 [1.49]; FIM, 19.13 [1.36]) as compared with other clinics. Implementation barriers were cost and patients' nonadherence to visits.

Conclusions

There is variability of readiness yet high levels of perceived acceptability and appropriateness of implementing LAI CAB/RPV among Ryan White clinics, necessitating tailored interventions for successful implementation. A special focus on addressing the barriers of adherence and the cost of implementation is needed.

Factors Associated with Preferences for Long-Acting Injectable Antiretroviral Therapy Among Adolescents and Young People Living with HIV in South Africa

Long-acting injectable anti-retroviral therapy (LAART) may overcome barriers to long-term adherence and improve the survival of adolescents and young people living with HIV (AYLHIV). Research on the acceptability of LAART for this age-group is limited. We asked 953 AYLHIV about their preferred (theoretical) ART mode of delivery (pill, injectable, or other) in 2017-2018, before LAART was available or known to AYLHIV in South Africa. One in eight (12%) AYLHIV preferred LAART over single or multiple pill regimens. In multivariate analyses, six factors were associated with LAART preference: medication stock-outs (aOR = 2.56, 95% CI 1.40-4.68, p = 0.002), experiencing side-effects (aOR = 1.84, 95% CI 1.15-2.97, p = 0.012), pill-burden (aOR = 1.88, 95% CI 1.20-2.94, p = 0.006), past-year treatment changes (aOR = 1.63, 95% CI 1.06-2.51, p = 0.025), any HIV stigma (aOR = 2.22, 95% CI 1.39-3.53, p ≤ 0.001) and recent ART initiation (aOR = 2.02, 95% CI 1.09-3.74, p = 0.025). In marginal effects modelling, 66% of adolescents who experienced all factors were likely to prefer LAART, highlighting the potential high acceptability of LAART among adolescents and young people living with HIV struggling to adhere and have good HIV treatment outcomes. Adolescent boys who reported high ART pill burden were more likely to prefer LAART than their female peers in moderation analyses, suggesting that LAART may be particularly important to improve treatment outcomes among male AYLHIV as they become older. Adding LAART to existing treatment options for AYLHIV, particularly higher risk groups, would support AYLHIV to attain and sustain viral suppression-the third 95, and reduce their risk of AIDS-related mortality.

Exploring the dynamics of the quality of HIV care experienced by female sex workers living in the Dominican Republic

Despite increased attention and efforts to improve HIV care among female sex workers (FSWs), they continue to have suboptimal HIV outcomes. Exploring the socio-structural dynamics related to the quality of HIV care received by FSWs is critical to further strengthen interventions to improve their HIV care continuum outcomes. In this study, we conducted two rounds of qualitative in-depth interviews with 20 FSWs living with HIV in the Dominican Republic to explore how healthcare experiences contributed to their quality of HIV care. Data was analyzed using a thematic analytic approach exploring diverse structural and relational aspects of the quality of HIV care affecting FSWs as they navigate the clinic environment. Results indicated that quality of HIV care was influenced by both structural and relational factors within clinics. At the structural level, insufficient stock of antiretroviral therapy and the financial burden created by HIV care related costs hindered FSWs' satisfaction with their current HIV care and presented a barrier in FSWs' ability to access HIV care services. Quality of care was also closely linked to relational aspects of the HIV care environment, including FSWs' relationship and communication with their clinical providers, as FSWs often expressed their satisfaction with HIV care experiences based on these interpersonal factors. Lastly, personal agency emerged as an important factor contributing to the quality of HIV care, specifically as FSWs' treatment literacy resulted in greater advocacy and demands for quality care. Programmatic efforts should be directed to improving the quality of HIV care experiences of FSWs in the clinic environment. These include addressing resource shortages, promoting positive and effective patient-provider relationships, and facilitating HIV treatment education opportunities for FSWs.

Injectable Long-Acting Cabotegravir-Rilpivirine Therapy for People Living With HIV/AIDS: Addressing Implementation Barriers From the Start

ABSTRACT

Injectable cabotegravir and rilpivirine (CAB/RPV), administered bimonthly by a medical provider, is convenient and improves privacy and medication management. One year after approval, myriad implementation barriers threaten the access and sustainability of this life-saving innovation: (1) eligibility issues (viral suppression, drug resistance, and failed oral regimens); (2) injection requires medical provider and transportation to facility; (3) strict medication adherence; (4) life challenges-mental health, homelessness, joblessness; and (5) lack of insurance and high cost. Universal implementation of CAB/RPV calls for social, human, and health organizations to partner and provide HIV continuum of care and prevention services to facilitate CAB/RPV access and maintenance and for transparent health insurance billing practices to abate uncertainty concerning CAB/RPV's classification as a pharmaceutical or medical benefit and related cost implications.

Relugolix: Five Reasons Why the US Food and Drug Administration Should Have Exercised Restraint

We highlight concerns regarding the approval of relugolix for patients with prostate cancer. These include the unsuitable comparator arm and primary endpoint in the HERO trial, as well as potential selection bias and the poor representativeness of the trial population. Dosing adherence to a daily tablet may also be an issue in comparison to injections at 3-mo intervals. Rigorous postmarketing trials of relugolix assessing clinically meaningful endpoints for these patients are needed.

Long-Acting Injectable Therapy for People with HIV: Looking Ahead with Lessons from Psychiatry and Addiction Medicine

Long-acting injectable antiretroviral medications are new to HIV treatment. People with HIV may benefit from a treatment option that better aligns with their preferences, but could also face new challenges and barriers. Authors from the fields of HIV, substance use treatment, and mental health collaborated on this commentary on the issues surrounding equitable implementation and uptake of LAI ART by drawing lessons from all three fields. We employ a socio-ecological framework beginning at the policy level and moving through the community, organizational, interpersonal, and patient levels. We look at extant literature on the topic as well as draw from the direct experience of our clinician-authors.

Patient preferences and health state utilities associated with the treatment process of antiretroviral therapy for people living with HIV

PURPOSE

People living with HIV (PLHIV) have reported challenges associated with daily oral antiretroviral therapy (ART), including missed doses, negative psychological impact, and difficulty remaining discreet while at home or traveling. Recently approved long-acting injectable (LAI) ART may help eliminate these concerns. The purpose of this study was to examine patient preferences and estimate health state utilities associated with oral and LAI treatment for ART.

METHODS

Four health state vignettes were developed based on published literature, clinician interviews, and a pilot study. All vignettes included the same description of HIV, but differed in treatment regimens: (A) single daily oral tablet, (B) two daily oral tablets, (C) injections once monthly, and (D) injections every two months. PLHIV in the UK reported their preferences and valued the health states in time trade-off utility interviews.

RESULTS

The sample included 201 PLHIV (83.1% male; mean age = 44.9y). The health states frequently selected as most preferable were D (n = 119; 59.2%) and A (n = 75; 37.3%). Utility differences among health states were relatively small, which is typical for treatment process utilities (mean utilities: A, 0.908; B, 0.905; C, 0.900; D, 0.910). Statistically significant differences in utility were found for one vs. two tablets and injections every month vs. every two months (p < 0.001). Participants' quotations highlight the wide range of reasons for treatment process preferences.

CONCLUSIONS

Current results indicate that many PLHIV would prefer LAI ART. The reported utilities may be useful in economic modeling comparing oral vs. LAI ART.

‘We want it all’: ART preferences assessed by D esirability of O utcome R anking

OBJECTIVES

Understanding how people living with HIV (PLWH) view antiretroviral therapy (ART) prescribing choices is fundamental to patient-centred care. We used the Desirability of Outcome Ranking (DOOR) approach to explore patient ART preferences.

METHODS

Seventy-four PLWH entered the study, 20 into the 'pilot study', and 54 in the 'comparative study'. Participants ranked five different hypothetical patient stories by desirability. Each story comprised five narrative lines, each line addressing one treatment characteristic drawn from one of five pre-selected domains (treatment failure, treatment difficulty, adverse effects, long-term complications, life events). Narrative lines could be favourable or adverse. In the pilot study the number of adverse domains varied from one to five. Comparative study stories were fixed at two adverse versus three favourable domains, to test the relative ranking of different domains.

RESULTS

The pilot study identified a relationship between the number of adverse domains and rank (R²  = 0.54; p < 0.0001, Friedman test), however pairwise differences in ranking were not significant beyond three adverse domains. In the comparative study, all domains were ranked equally across the cohort (p = 0.88; Friedman test). In pre-defined demographic subgroup analyses, women ranked the 'treatment failure' domain significantly less desirable than men (p = 0.0014, Mann-Whitney test).

CONCLUSIONS

People living with HIV appear to care equally about all aspects of ART. The observation that male and female PLWH have different treatment priorities merits further investigation in larger studies. Interindividual differences highlight the importance of individualized shared decision-making and treatment personalization. DOOR may have a role as a pre-treatment assessment tool as well as a research technique.

Cabotegravir: The first long-acting injectable for HIV pre-exposure prophylaxis

DISCLAIMER

In an effort to expedite the publication of articles, AJHP is posting manuscripts online as soon as possible after acceptance. Accepted manuscripts have been peer-reviewed and copyedited, but are posted online before technical formatting and author proofing. These manuscripts are not the final version of record and will be replaced with the final article (formatted per AJHP style and proofed by the authors) at a later time.

PURPOSE

The purpose of this article is to review the pharmacology, efficacy, and safety of the integrase inhibitor cabotegravir for HIV pre-exposure prophylaxis, including data from clinical trials.

SUMMARY

A narrative review was performed by searching PubMed/MEDLINE databases to identify relevant articles published between March 2014 and December 2021 using the keyword terms cabotegravir and Apretude and the search strings "long-acting injectable AND human immunodeficiency virus" and "pre-exposure prophylaxis AND human immunodeficiency virus." All relevant English-language articles evaluating the pharmacology, efficacy, or safety of cabotegravir in humans for HIV pre-exposure prophylaxis were included. Additional data were obtained from prescribing information, references of identified articles, and abstracts from scientific meetings. Cabotegravir has been approved by the Food and Drug Administration and is considered both safe and effective for HIV pre-exposure prophylaxis. It is the first long-acting injectable medication approved for this indication. Phase 3 clinical trials have demonstrated the noninferiority of cabotegravir to currently recommended oral once-daily dosing regimens. Injection-site reactions were common in clinical trials of cabotegravir and occurred in up to 81% of trial participants. Costs associated with the long-acting injectable formulation must also be considered.

CONCLUSION

Cabotegravir is a novel bimonthly, injectable option for pre-exposure HIV prophylaxis for high-risk adolescents and adults weighing at least 35 kg.

Monthly injectable cabotegravir/rilpivirine to manage HIV infection in adults

ABSTRACT

The FDA recently approved a unique treatment regimen for management of HIV-1 infection in adults. A one-time per month injection of cabotegravir/rilpivirine can replace a current, stable antiretroviral regimen in those with virologic suppression, without history of treatment failure, or known or suspected resistance with cabotegravir or rilpivirine. A one-month oral trial should be initiated before switching to the extended-release injectable formulation. Cabotegravir/rilpivirine showed continued virologic suppression without clinically relevant changes in CD4+ cell counts. Clinicians should understand this new HIV regimen, its indications and suitability for select patients, administration and dosing, interactions, and most reported adverse events.

Long-Acting Injectable ART and PrEP Among Women in Six Cities Across the United States: A Qualitative Analysis of Who Would Benefit the Most

Long-acting injectable (LAI) modalities have been developed for ART and PrEP. Women face unique barriers to LAI use yet little research has examined women's perceptions of potential LAI HIV therapy candidates. We conducted 89 in-depth interviews at six Women's Interagency HIV Study (WIHS) sites with women living with HIV (n = 59) and HIV-negative women (n = 30) from 2017 to 2018. Interviews were recorded, transcribed, and analyzed using thematic content analysis. Participants identified specific sub-populations who could most benefit from LAI over daily pills: (1) young people; (2) women with childcare responsibilities; (3) people with adherence-related psychological distress; (4) individuals with multiple sex partners; and (5) people facing structural insecurities such as homelessness. Women are underserved by current HIV care options and their perspectives are imperative to ensure a successful scale-up of LAI PrEP and LAI ART that prioritizes equitable access and benefit for all individuals.

Promise, perils and cautious optimism: the next frontier in long-acting modalities for the treatment and prevention of HIV

PURPOSE OF REVIEW

This paper provides a critical review of recent therapeutic advances in long-acting (LA) modalities for human immunodeficiency virus (HIV) treatment and prevention.

RECENT FINDINGS

LA injectable antiretroviral therapy (ART) has been approved in the United States, Canada and Europe; the United States also has approved LA injectable preexposure prophylaxis (PrEP) and the World Health Organization has recommended the vaginal PrEP ring. Current LA PrEP modalities in clinical trials include injections, films, rings, and implants; LA ART modalities in trials include subcutaneous injections and long-term oral pills. Although LA modalities hold incredible promise, global availability is inhibited by long-standing multilevel perils including declining multilateral funding, patent protections and lack of political will. Once available, access and uptake are limited by factors such as insurance coverage, clinic access, labor markets, stigma, and structural racism and sexism. These must be addressed to facilitate equitable access for all.

SUMMARY

There have been tremendous recent advances in the efficacy of LA ART and PrEP modalities, providing renewed hope that 'ending the HIV epidemic' is within reach. However, pervasive socio-structural inequities limit the promise of LA modalities, highlighting the need for cautious optimism in light of the embedded inequities in the trajectory of research, development, and population-level implementation.

Perspectives on preparing for long-acting injectable treatment for HIV among consumer, clinical and nonclinical stakeholders: A qualitative study exploring the anticipated challenges and opportunities for implementation in Los Angeles County

Long-acting injectable (LAI) antiretroviral therapy (ART) is a novel HIV treatment option for people with HIV. The first LAI ART regimen for HIV treatment received regulatory approval in the United States in January 2021. In February 2020, we collected qualitative data from 18 consumers and 23 clinical and non-clinical stakeholders to catalog anticipated individual-consumer, healthcare system, and structural levels barriers and facilitators to LAI ART implementation in Los Angeles County, California. Thematic analysis was guided by the CFIR implementation science model. CFIR constructs of intervention characteristics, individual characteristics, outer and inner setting, intervention characteristics, and implementation process emerged in analysis. Under intervention characteristics, anticipated facilitators included the relative advantage of LAI ART over pills for adherence and reduced treatment management burden and related anxiety; anticipated barriers included non-adherence to injection appointments, concerns of developing HIV resistance, discomfort with injection and cost. Anticipated facilitators based on individual characteristics included overall acceptability based on knowledge and positive beliefs about LAI ART. Participant noted several characteristics of the outer setting that could negatively impact implementation, such as medical mistrust, external policies, and LAI ART eligibility (i.e., to be virally suppressed prior to initiation). Participants were optimistic about the potential to decrease stigma but expressed that provider willingness for adoption could be hindered by challenges in organizational inner setting related to payment authorizations, increased staffing needs, medication procurement and storage, and provider and healthcare system readiness. Results from this pre-implementation study may inform rollout and scale-up of LAI ART in Los Angeles County.

Multi-level considerations for optimal implementation of long-acting injectable antiretroviral therapy to treat people living with HIV: perspectives of health care providers participating in phase 3 trials

Background

Long-acting injectable antiretroviral therapy (LA ART) has been shown to be non-inferior to daily oral ART, with high patient satisfaction and preference to oral standard of care in research to date, and has recently been approved for use in the United States and Europe. This study examined the perspectives of health care providers participating in LA ART clinical trials on potential barriers and solutions to LA ART roll-out into real world settings.

Methods

This analysis draws on two data sources: (1) open-ended questions embedded in a structured online survey of 329 health care providers participating in the ATLAS-2 M trial across 13 countries; and (2) in-depth interviews with 14 providers participating in FLAIR/ ATLAS/ATLAS-2 M trials in the United States and Spain. Both assessments explored provider views and clinic dynamics related to the introduction of LA ART and were analyzed using thematic content analysis. The Consolidated Framework for Implementation Research (CFIR) was drawn on as the conceptual framework underpinning development of a model depicting study findings.

Results

Barriers and proposed solutions to LA ART implementation were identified at the individual, clinic and health system levels. Provider perceptions of patient level barriers included challenges with adhering to frequent injection appointments and injection tolerability. Proposed solutions included patient education, having designated staff for clinic visit retention, and clinic flexibility with appointment scheduling. The main provider concern was identifying appropriate candidates for LA ART; proposed solutions focused on patient provider communication and decision making. Clinic level barriers included the need for additional skilled individuals to administer injections, shifts in workflow as demand increases and the logistics of cold-chain storage. Proposed solutions included staff hiring and training, strategic planning around workflow and logistics, and the possibility of offering injections in other settings, including the home. Health system level barriers included cost and approvals from national regulatory bodies. Potential solutions included governments subsidizing treatment, ensuring cost is competitive with oral ART, and offering co-pay assistance.

Conclusions

Results suggest the importance of multi-level support systems to optimize patient-provider communication and treatment decision-making; clinic staffing, workflow, logistics protocols and infrastructure; and cost-related factors within a given health system.

The LAIs Are Coming! Implementation Science Considerations for Long-Acting Injectable Antiretroviral Therapy in the United States: A Scoping Review

Long-acting injectable antiretroviral therapy (LAI-ART) is one of the latest advancements in HIV control with the potential to overcome oral ART barriers to adherence. The objective of this article is to anticipate and examine implementation considerations for LAI-ART using components of the PRISM model, a Practical, Robust Implementation and Sustainability Model for integrating research findings into practice. We conducted a scoping review from January to August 2020 of the growing literature on LAI-ART implementation and other fields using LAI therapies. Key considerations regarding LAI-ART were parsed from the searches and entered into the PRISM implementation science framework. The PRISM framework posed multiple questions for consideration in the development of an optimal implementation strategy for LAI-ART in the United States. These questions revealed the necessity for more data, including acceptability of LAI-ART among many different subgroups of people living with HIV (PLWH), cost effectiveness, patient satisfaction, and patient-reported outcomes, as well as more detailed information related to the external environment for optimal LAI-ART implementation. Ethical considerations of LAI-ART will also need to be considered. The anticipation of, and excitement for, LAI-ART represent the hope for a new direction for HIV treatment that reduces adherence barriers and improves prognoses for PLWH. We have a unique window of opportunity to anticipate implementation considerations for LAI-ART, so this new therapy can be used to its fullest potential. Outstanding questions remain, however, that need to be addressed to help achieve HIV suppression goals in diverse populations.

The Promise of Improved Adherence With Long-Acting Antiretroviral Therapy: What Are the Data?

As with other chronic conditions, adherence to daily medications remains a challenge for many individuals living with HIV due to structural, behavioral, and social barriers. Unfortunately, high levels of adherence to antiretroviral therapy are required to maintain virologic suppression. Alternative approaches are being explored to decrease the burden of daily pill administration, including long-acting injectable, oral, and implantable products. Phase 3 data support the efficacy of nanoformulated injectable cabotegravir and rilpivirine for HIV treatment in patients with undetectable viremia, but we have yet to learn how this strategy may benefit those with medication adherence challenges. Despite this, the affected community and HIV providers are very interested in exploring the role of long-acting therapies to address some types of barriers to medication adherence. This review summarizes available information about the potential for long-acting therapy to improve adherence for some patients and outlines associated opportunities and challenges with the implementation of long-acting therapy for the treatment and prevention of HIV.

Reasons People Living with HIV Might Prefer Oral Daily Antiretroviral Therapy, Long-Acting Formulations, or Future HIV Remission Options

A growing body of research is beginning to elucidate reasons people living with HIV (PLWHIV) might prefer oral daily antiretroviral treatment (ART) compared with emerging long-acting ART (LA-ART) or HIV remission strategies under investigation. Our objective is to provide qualitative insights into the reasons why PLWHIV might prefer one of these HIV control therapies over others. From May to August 2018, we implemented a semistructured cross-sectional survey of PLWHIV in the United States to better understand patient preferences around various HIV treatment and remission options. Using free text, respondents were asked to explain why they preferred one HIV control option over the other two. We analyzed responses to the open-ended survey questions on reasons for preferring oral daily ART versus LA-ART versus HIV remission strategies using conventional content analysis. The results showed that PLWHIV preferred oral daily ART because of its familiarity and known safety and efficacy profile, whereas those who preferred LA-ART would value the convenience it offers. Finally, HIV remission strategies would be preferred to avoid taking ART altogether. The qualitative results provide insights into reasons why PLWHIV in the United States might prefer oral daily ART versus novel therapies. More importantly, they provide information to better align HIV virological control strategies with end-user perspectives. To make informed choices around evolving HIV therapeutics, PLWHIV and HIV care providers would benefit from decision tools to better assess options and trade-offs. More research is needed on how best to effectively support PLWHIV and HIV care providers in shared decision-making.

"A dream come true": Perspectives on long-acting injectable antiretroviral therapy among female sex workers living with HIV from the Dominican Republic and Tanzania

BACKGROUND

Long-acting injectable antiretroviral therapy (LA ART) was found to be non-inferior to daily oral ART in Phase 3 clinical trials. LA ART may offer an important alternative for people living with HIV with challenges adhering to daily oral ART or preferences for non-pill-based regimens.

METHODS

Using a mixed methods approach integrating survey, in-depth interview and biological data from female sex workers (FSW) living with HIV in Tanzania (N = 208) and the Dominican Republic (DR) (N = 201), we assessed factors associated with the potential likelihood of LA ART use if it were available. We conducted multivariate logistic regression and thematic content analysis.

RESULTS

Likelihood of LA ART use was high with 84.92% of FSW from the DR and 92.27% of FSW from Tanzania reporting they would be "likely" or "very likely" to use LA ART if available (p = 0.02). In Tanzania better HIV-related patient-provider communication (AOR 4.58; 95% CI 1.90-11.05) and quality of HIV clinical care (AOR 3.68; 95% CI 1.05-12.86) were positively associated with the high likelihood of LA ART use. In the DR, easier clinic access was associated with a higher likelihood of LA ART use (AOR 3.04; 95% CI 1.41-6.56), as was greater monthly income from sex work (AOR 2.37; 95% CI 1.27-4.41). In both settings, years on ART was significantly associated with a strong likelihood of LA ART use (TZ: AOR 1.16 per year; 95% CI 1.00-1.34/DR: AOR 1.07 per year; 95% CI 1.00-1.14). Qualitative findings underscored enthusiasm for LA ART and reinforced its potential to address sex work-specific barriers to daily oral ART adherence including work-related schedules and substance use.

CONCLUSIONS

We found a high likelihood of LA ART use if available among FSW in two diverse settings and documented barriers to future uptake. Community-driven approaches which include tailored health education and improved patient-provider communication and quality of care, as well as strategies to facilitate appointment adherence are needed to optimize LA ART use among FSW.
