Event-driven or intermittent dosing of PrEP in populations beyond cisgender men who have sex with men would offer a promising alternative by fitting prevention into the diverse lifestyles of affected populations and thereby advancing health equity. Evidence from PrEP clinical trials, pharmacokinetic studies, modelling studies, and real-world observational research suggests that event-driven PrEP could be a flexible and inclusive option, yet optimal dosing has not been established across sex and gender spectrums. To advance PrEP equity through inclusivity, studies on event-driven PrEP should include people across the gender spectrum. Real-world demonstration studies and simulation studies of optimal dosing strategies are needed. While awaiting further evidence, clinical providers can offer shared decision making and counselling on available data to include event-driven dosing as an option, especially when daily oral, locally acting, or injectable PrEP are not acceptable or preferred methods. Wider access to diverse PrEP options for all populations fosters a more inclusive and effective global HIV prevention strategy.</p>","PeriodicalId":48725,"journal":{"name":"Lancet Hiv","volume":" ","pages":"e143-e153"},"PeriodicalIF":12.8,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142957281","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Participants were eligible if they were assigned female sex at birth, aged 18-25 years, not living with HIV, sexually active, newly initiating PrEP, had regular access to a mobile telephone, and could read. Using sequentially numbered, sealed, opaque envelopes containing group allocation, a staff member assigned enrolled participants (1:1) to receive one of two adherence-support interventions: once per week two-way SMS communication or participation in a WhatsApp peer-support group. Participants assigned to WhatsApp were put into groups with approximately 25 participants, during which they were prompted by staff facilitators to discuss any challenges with PrEP use or other events happening in their lives. The allocation sequence was generated by the data manager using random numbers with variable block sizes between 10 and 14. Only trial investigators were masked to participant intervention assignments; participants, people giving interventions, people assessing outcomes, and people analysing data were not masked to group assignment. All enrolled participants were offered PrEP (ie, co-formulated, once per day oral emtricitabine 200 mg and tenofovir disoproxil fumarate 300 mg). The primary outcome was high PrEP adherence at month 9, defined as concentration of tenofovir diphosphate on dried blood sample of 700 fmol per punch or more. At month 3, participants with low PrEP adherence were randomly assigned to a secondary, intensified intervention of issue-focused counselling once per month or drug-level feedback counselling based on PrEP drug concentrations at months 3 and 6. The protocol was registered at ClinicalTrials.gov (NCT04038060) and the trial is complete.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Findings: &lt;/strong&gt;Participants were enrolled and followed up between May 16, 2019, and Jan 25, 2022.

The possibilities for cell and gene therapy-based products for an HIV cure are rapidly expanding. In a multi-stakeholder consensus process of clinical experts and civil society, including representatives from low-income and middle-income countries, participants generally agreed on the optimal targets, whereas consensus on the minimal targets was not reached on every parameter. There was less agreement on the minimal targets for ex-vivo than in-vivo therapies given the complexity of ex-vivo interventions. The TPP is planned to be updated at regular intervals.

We aimed to characterise how well atherosclerotic cardiovascular disease (ASCVD) risk scores used in clinical guidelines perform among people with HIV globally.METHODSIn this prospective cohort study leveraging REPRIEVE data, we included participants aged 40-75 years, with low-to-moderate traditional cardiovascular risk, not taking statin therapy. REPRIEVE participants were enrolled from sites in 12 countries across Global Burden of Disease Study (GBD) regions. We assessed the performance of the pooled cohort equations (PCE) risk score for ASCVD and the data-collection on adverse effects of anti-HIV drugs (D:A:D) risk score. We calculated C statistics, observed-to-expected (OE) event ratios, and Greenwood-Nam-D'Agostino goodness-of-fit (GND) statistics, overall and in subgroups by race, sex, and GBD regions (clustering low-income and middle-income countries and high-income countries). We did a recalibration for PCE risk score among people with HIV in high-income countries. REPRIEVE was registered with ClinicalTrials.gov, NCT02344290.FINDINGSWe included 3893 participants, recruited between March 26, 2015, and July 31, 2019. The median age was 50 years (IQR 45-55), with 2684 (69%) male and 1209 (31%) female participants. 1643 (42%) were Black or African American, 1346 (35%) participants were White, 566 (15%) were Asian, and 338 (9%) were recorded as other race. Overall, discrimination of the PCE risk score was moderate (C statistic 0·72 [95% CI 0·68-0·76]) and calibration was good (OE event ratio 1·11; GND p=0·87). However, calibration suggested overprediction of risk in low-income and middle-income countries and corresponding underprediction in high-income countries. When restricted to high-income countries, we found underprediction (OE event ratio &gt;1·0) among women (2·39) and Black or African American participants (1·64). Findings were similar for the D:A:D risk score (C statistic 0·71 [0·65-0·77]; OE event ratio 0·89; p=0·68). Improved calibration of the PCE risk score in high-income countries was achieved by multiplying the original score by 2·8 in Black or African American women, 2·6 in women who were not Black or African American, and 1·25 in Black or African American men.INTERPRETATIONAmong the global cohort of people with HIV in REPRIEVE, the PCE risk score underpredicted cardiovascular events in women and Black or African American men in high-income countries and overpredicted cardiovascular events in low-income and middle-income countries. Underprediction in subgroups should be considered when using the PCE risk score to guide statin prescribing for cardiovascular prevention among people with HIV in high-income countries. Additional research is needed to develop risk scores accurate in predicting ASCVD among people with HIV in low-income and middle-income countries.FUNDINGUS National Institutes of Health, Kowa Pharmaceuticals Am","PeriodicalId":48725,"journal":{"name":"Lancet Hiv","volume":"10 1","pages":""},"PeriodicalIF":16.1,"publicationDate":"2025-01-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142991815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to evaluate the efficacy of dolutegravir plus lamivudine in the absence of information on baseline resistance testing in treatment-naive people with HIV.METHODSWe did an open-label, non-inferiority, single-centre, phase 4, randomised controlled study (D2ARLING), designed to assess the efficacy and safety of dolutegravir plus lamivudine in treatment-naive people with HIV with no available baseline resistance testing. We included participants aged 18 years or older with HIV-1 diagnosis who were naive to antiretroviral therapy and had no baseline genotypic resistance testing result available. We randomly assigned (1:1) participants to receive dolutegravir 50 mg plus lamivudine 300 mg or a three-drug regimen including dolutegravir 50 mg plus tenofovir disoproxil fumarate 300 mg and either emtricitabine 200 mg or lamivudine 300 mg. Randomisation was stratified by baseline HIV-1 RNA (≤100 000 vs &gt;100 000 copies per mL) and CD4 cell count (&lt;200 vs ≥200 cells per μL). Per protocol, we performed genotypic drug-resistance testing on day 1 and it remained double-masked throughout the study, simulating a scenario of inaccessibility of baseline resistance testing. The primary endpoint was the proportion of participants with plasma HIV-1 RNA less than 50 copies per mL at week 48 (intention-to-treat exposed analysis via the Snapshot algorithm) with prespecified non-inferiority margin of 10%. This trial is registered with ClinicalTrials.gov (NCT04549467).FINDINGSBetween Nov 17, 2020, and Aug 31, 2022, 214 participants were randomly assigned to and treated with dolutegravir plus lamivudine (n=106) or dolutegravir plus tenofovir disoproxil fumarate and either emtricitabine or lamivudine (n=108). Median age of participants was 31 years (IQR 26-39) and 49 (23%) were female. At baseline, 66 (31%) of participants had an HIV-1 RNA viral load of more than 100 000 copies per mL, and 44 (21%) had a CD4 T-cell count of less than 200 cells per μL. At week 48, 97 (92%) of 106 participants in the dolutegravir plus lamivudine group and 96 (89%) of 108 participants in the dolutegravir plus tenofovir disoproxil fumarate with either emtricitabine or lamivudine group had HIV-1 RNA of less than 50 copies per mL (difference 2·62%; 95% CI -5·3 to 10·6), showing non-inferiority of dolutegravir plus lamivudine to the three-drug regimen. None of the participants in the dolutegravir plus lamivudine group and two in the control group had protocol-defined virological failure, and none developed treatment-emergent resistance mutations to any of the study drugs.
