We searched for completed and ongoing studies published before May 2024 in PubMed, Embase, Cochrane Library, CINAHL, and clinicaltrial.gov.  Overall, 11 studies assessing adherence benchmarks focusing on (n = 5) or involving (n = 6) cisgender women were included. Women-specific median steady-state TFV-DP concentration for daily dosing ranged from 17 to 51 fmol/10⁶ in PBMC and 1389 to 1685 fmol/punch in DBS in non-pregnant women; 50 to 71 fmol/10⁶ in PBMC and 583 to 965 fmol/punch in DBS in pregnant women; and 618 to 1406 fmol/punch in DBS in postpartum women. DBS TFV-DP levels were 14-43% lower in pregnancy versus postpartum or non-pregnant periods, but PBMC TFV-DP levels appear to be comparable. Clinical and modeling studies demonstrate effective HIV protection for women taking at least four doses/week of oral TDF-based PrEP, and emerging evidence suggests that systemic drug levels are more likely to be predictive of efficacy than local tissue levels at the site of exposure. The preponderance of emerging evidence points to comparable efficacy and similar adherence requirement for women as men among those with detectable drug levels, although there was an indication that the highest achievable efficacy may be reached at a lower adherence level in men than women. In this review, we found evidence that women-specific TFV-DP adherence benchmarks in DBS and PBMC are within range of US-based historical thresholds derived from healthy men and women. Emerging evidence suggests that imperfect but adequate adherence to oral FTC/TDF PrEP with at least four doses/week provides sufficient HIV protection in cisgender women as it does in MSM, but more data are still needed to refine intrinsic achievable efficacy estimates for cisgender women.</p>","PeriodicalId":10930,"journal":{"name":"Current HIV/AIDS Reports","volume":null,"pages":null},"PeriodicalIF":3.7,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141906176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through the introduction of additional PrEP methods, including vaginal rings and long-acting injectable formulations, health systems globally are on the cusp of offering PrEP methods that vary by route of administration, efficacy, and frequency of use. With PrEP choice, it will be important to explore PrEP use patterns to better understand how the ability to choose and switch products affects coverage and continuation.

Key evidence gaps include understanding product switching in the context of full versus constrained choice, switching in the context of temporary need, and developing interventions that promote product switching for those who could benefit. Providing choice and allowing people to start, stop, and switch products according to their needs and desires is a core component of a rights-based approach to HIV prevention. More research is needed to better understand what drives use patterns, including switching, and how to leverage choice to improve coverage. Standard definitions -some of which have been proposed in this review-are needed to inform comparable measurement.
