Abstract
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.

Abstract
Background: Long-acting injectable (LAI) antiretroviral therapy (ART) may offer persons living with HIV (PLWH) an attractive alternative to pill-based treatment options, yet acceptability data remain scant, especially in sub-Saharan Africa. Methods: We conducted 6 focus group discussions with PLWH, including key stake holder groups, and analyzed data with content analysis. Results: Initial reactions to the idea of LAI-ART were often positive. The primary advantages voiced were potential to facilitate improved adherence and alleviate the burden of daily pill-taking while avoiding inadvertent disclosure and HIV stigma. Potential side effects were a particular concern of the women. Most participants preferred clinic-based administration over self-injections at home due to concerns about safety, privacy, and potential need for refrigeration. Conclusions: LAI-ART may be acceptable in Kenya, provided injections are infrequent and delivered in a clinic setting. However, HIV stigma, fear of potential side effects, and limited clinical capacity would need to be addressed.

Abstract
Medications for antiretroviral therapy (ART) and preexposure prophylaxis (PrEP) are currently daily pill regimens, which pose barriers to long-term adherence. Long-acting injectable (LAI) modalities have been developed for ART and PrEP, but minimal LAI-focused research has occurred among women. Thus, little is known about how women's history of injection for medical or nonmedical purposes may influence their interest in LAI. We conducted 89 in-depth interviews at 6 sites (New York, NY; Chicago, IL; San Francisco, CA; Atlanta, GA; Chapel Hill, NC; Washington, DC) of the Women's Interagency HIV study. Interviews occurred with women living with HIV (n = 59) and HIV-negative women (n = 30) from November 2017 to October 2018. Interviews were recorded, transcribed, and analyzed using thematic content analysis. Women's prior experiences with injections occurred primarily through substance use, physical comorbidities, birth control, or flu vaccines. Four primary categories of women emerged; those who (1) received episodic injections and had few LAI-related concerns; (2) required frequent injections and would refuse additional injections; (3) had a history of injection drug use, of whom some feared LAI might trigger a recurrence, while others had few LAI-related concerns; and (4) were currently injecting drugs and had few LAI-related concerns. Most women with a history of injectable medication would prefer LAI, but those with other frequent injections and history of injection drug use might not. Future research needs to address injection-related concerns, and develop patient-centered approaches to help providers best identify which women could benefit from LAI use.

Abstract
Addressing women's low uptake of HIV pre-exposure prophylaxis (PrEP) requires improved understanding of their product preferences. Such preferences should be contextualized according to other aspects of their reproductive health, including their contraception practices. We investigated women's preferences across 10 PrEP modalities currently available or under study and examined associations between PrEP modality preferences and contraception practices. Heterosexually active women recently engaged in care at Connecticut Planned Parenthood centers (n = 563) completed an online survey. Participants were presented with images and descriptions of 10 PrEP modalities and asked to indicate their preference and specify their reasoning in an open-response format. Participants also reported prior and current use of 16 contraception modalities along with relationship, sexual health, and sociodemographic characteristics. The sample included women ages 18-45 (45.3% 25 or younger) who were predominantly non-Hispanic black (35.7%) or white (33.7%). All PrEP modalities presented were preferred by at least some women, with daily pills (24.9%), injections (24.3%), and invisible implants (14.9%) preferred most commonly. Across all modalities, associated reasoning often centered around ease of use and comfort. Coincidence with contraception modality was the third-most common reason underlying women's preferences. Women currently using the analogous contraception modality versus never having used it had higher odds of preferring PrEP daily pills [adjusted odds ratio (AOR) = 2.03], injections (AOR = 8.45), invisible implants (AOR = 11.63), and vaginal rings (AOR = 8.66). Diversification of available PrEP modalities and prioritization of those coinciding with popular contraception practices-especially daily pills, injections, and implants-could optimize PrEP acceptability, encourage PrEP uptake, and ultimately reduce HIV incidence among women.

Abstract
To better understand acceptability of long-acting injectable antiretroviral treatment (LAI-ART) regimens for HIV management, we conducted seven semi-structured focus group discussions with experienced HIV care providers and persons living with HIV (PLWH) and five individual interviews with parents of children living with HIV in the western United States. Although providers were wary about a potential negative impact on consistent engagement in care, they predicted that patients, especially those with adherence challenges, would be enthusiastic about LAI options. Many PLWH, especially young adults, welcomed the option of an LAI-ART regimen; however, others feared injections and expressed concerns about possible side effects, dosing more frequent than every 2 weeks, additional costs, and lower efficacy. Parents' interest varied according to their child's age and sensitivity to injections. In summary, potential users considered LAI-ART generally acceptable yet voiced possible concerns as well, especially if their current pill-based regimen was effective in achieving viral suppression.

Abstract
Oral pre-exposure prophylaxis for the prevention of HIV-1 transmission (HIV PrEP) has been widely successful as demonstrated by a number of clinical trials. However, studies have also demonstrated the need for patients to tightly adhere to oral dosing regimens in order to maintain protective plasma and tissue concentrations. This is especially true for women, who experience less forgiveness from dose skipping than men in clinical trials of HIV PrEP. There is increasing interest in long-acting (LA), user-independent forms of HIV PrEP that could overcome this adherence challenge. These technologies have taken multiple forms including LA injectables and implantables. Phase III efficacy trials are ongoing for a LA injectable candidate for HIV PrEP. This review will focus on the design considerations for both LA injectable and implantable platforms for HIV PrEP. Additionally, we have summarized the existing LA technologies currently in clinical and pre-clinical studies for HIV PrEP as well as other technologies that have been applied to HIV PrEP and contraceptives. Our discussion will focus on the potential application of these technologies in low resource areas, and their use in global women's health.

Abstract
This study aimed to identify patients' physical and psychosocial experiences of an investigational long-acting injectable PrEP product to aid in the development of patient and provider education materials. Twenty-eight participants of a Phase 2 safety, tolerability, and acceptability study of long-acting integrase inhibitor cabotegravir (CAB-LA) were interviewed on their physical and psychosocial experiences of the injections. Five themes emerged through a framework analysis on these interview transcripts: (1) injection-related pain is highly variable across individuals; (2) pain is more impactful after the injections than during; (3) patient anxiety is critical, but does not determine the experience of injections and decreases over time; (4) intimacy and awkwardness of gluteal injections impacts patients' experiences; (5) patient education and care strategies can mitigate the above factors. These findings can inform further sociobehavioral research within Phase 3 efficacy trials of CAB-LA, as well as patient education and provider guidance for future injectable PrEP products.

Abstract
Pre-exposure prophylaxis (PrEP) provides a radically different HIV prevention option for women. Not only is PrEP the first discrete, woman-controlled method that is taken in advance of exposure, but it is both safe and highly effective, offering over 90% protection if taken daily. While multiple modalities of PrEP are in development ranging from vaginal rings to injectables and implants, only PrEP with oral tenofovir/emtricitabine is currently FDA-approved. Family planning clinics provide key access points for many women to learn about and obtain PrEP. By incorporating PrEP services into family planning care, family planning providers have the opportunity to meet women's expectations, ensure women are aware of and offered comprehensive HIV prevention options, and reverse emerging disparities in PrEP access. Despite real and perceived barriers to integrating PrEP into family planning care, providing PrEP services, ranging from education to onsite provision, is not only possible but an important component of providing high-quality sexual and reproductive healthcare to women. Lessons learned from early adopters will help guide those in family planning settings initiating or enhancing PrEP services.

Intramuscular injection of NMDTG (118 ± 8 mg/ml, 25.5 mg of DTG equivalents/kg of body weight) to three rhesus macaques led to plasma DTG levels of 86 ± 12 and 28 ± 1 ng/ml on days 35 and 91, respectively. The NMDTG platform showed no significant adverse events. Further modification may further extend the drug's apparent half-life for human use.

Abstract
There are ~900,000 new HIV infections among women every year, representing nearly half of all new HIV infections globally. In the US, nearly one-fifth of all new HIV infections occur among women, and women from racial and ethnic minority communities experience disproportionately high rates of new HIV infections. Thus, there is a need to develop and implement effective HIV prevention strategies for women in the US and internationally, with a specific need to advance strategies in minority communities. Previous studies have demonstrated that oral HIV pre-exposure prophylaxis (PrEP), the use of antiretroviral medications by HIV-uninfected persons to prevent HIV acquisition, can reduce HIV incidence among women who are adherent to PrEP. However, to date, awareness and uptake of PrEP among women have been very limited, suggesting a need for innovative strategies to increase the knowledge of and access to PrEP among women in diverse settings. This narrative review summarizes the efficacy and safety data of PrEP in women, discusses considerations related to medication adherence for women who use PrEP, and highlights behavioral, social, and structural barriers to maximize the effectiveness of PrEP in women. It also reviews novel modalities for PrEP in women which are being developed and tested, including topical formulations and long-acting injectable agents that may offer advantages as compared to oral PrEP and proposes a community-oriented, social networking framework to increase awareness of PrEP among women. If women are provided with access to PrEP and support to overcome social and structural barriers to adhere to PrEP, this prevention strategy holds great promise to impact the HIV epidemic among women in the US and globally.

Abstract
Background Preexposure prophylaxis (PrEP) is available as a daily pill for preventing infection with the human immunodeficiency virus (HIV). Innovative methods of administering PrEP systemically or topically are being discussed and developed. Objective The objective of our study was to assess attitudes toward different experimental modalities of PrEP administration. Methods From April to July 2015, we recruited 1106 HIV-negative men who have sex with men through online social media advertisements and surveyed them about their likelihood of using different PrEP modalities. Participants responded to 5-point Likert-scale items indicating how likely they were to use each of the following PrEP modalities: a daily oral pill, on-demand pills, periodic injection, penile gel (either before or after intercourse), rectal gel (before/after), and rectal suppository (before/after). We used Wilcoxon signed rank tests to determine whether the stated likelihood of using any modality differed from daily oral PrEP. Related items were combined to assess differences in likelihood of use based on tissue or time of administration. Participants also ranked their interest in using each modality, and we used the modified Borda count method to determine consensual rankings. Results Most participants indicated they would be somewhat likely or very likely to use PrEP as an on-demand pill (685/1105, 61.99%), daily oral pill (528/1036, 50.97%), injection (575/1091, 52.70%), or penile gel (438/755, 58.01% before intercourse; 408/751, 54.33% after). The stated likelihoods of using on-demand pills (median score 4) and of using a penile gel before intercourse (median 4) were both higher than that of using a daily oral pill (median 4, P<.001 and P=.001, respectively). Compared with a daily oral pill, participants reported a significantly lower likelihood of using any of the 4 rectal modalities (Wilcoxon signed rank test, all P<.001). On 10-point Likert scales created by combining application methods, the reported likelihood of using a penile gel (median 7) was higher than that of using a rectal gel (median 6, P<.001), which was higher than the likelihood of using a rectal suppository (median 6, P<.001). The modified Borda count ranked on-demand pills as the most preferred modality. There was no difference in likelihood of use of PrEP (gel or suppository) before or after intercourse. Conclusions Participants typically prefer systemic PrEP and are less likely to use a modality that is administered rectally. Although most of these modalities are seen as favorable or neutral, attitudes may change as information about efficacy and application becomes available. Further data on modality preference across risk groups will better inform PrEP development.
