SER Familia: A Family-Based Intervention Addressing Syndemic Conditions Among Latino Immigrant Families
This study aims to prevent syndemic health conditions by decreasing acculturative stress and promoting resilience via SER Familia (Salud, Estrés y Resilencia en Familias/ Health, Stress, and Resilience in Families), a family-based intervention. SER Familia is a six-session intervention co-developed and delivered by community health workers (CHWs) that uses strategies to reduce acculturative stress, promote resilience, improve parent-child and family level health, while simultaneously helping families maintain strong social networks and better navigate community resources to address social determinants of health (SDOH). More specifically, investigators aim to: 1) Examine the efficacy of SER Familia to prevent or reduce the syndemic comprised of substance abuse, IPV, HIV risk, depression, and anxiety among Parents and Youth; and 2) Identify how individual, family, and community mechanisms of change related to acculturative stress and resilience mediates the effect of SER Familia.

Pharmacokinetic Study of Long-acting Antiretrovirals and Contraceptives in HIV
This study is being done to understand how long-acting injectable cabotegravir (CAB-LA) used for HIV pre-exposure prophylaxis (PrEP) and hormonal contraceptive methods affect each other when used at the same time. Women who are already using CAB-LA or not using PrEP will choose to join one of several groups based on whether they use injectable contraceptive (IM DMPA), an etonogestrel implant, or no hormonal contraceptive. Participants will have study visits every 4 to 12 weeks for up to 12 or 24 weeks after starting a contraceptive method to collect blood samples and measure levels of CAB-LA and hormone concentrations. The study will compare these levels to see if taking CAB-LA changes hormone concentrations or if using hormonal contraception changes CAB-LA drug levels. Safety, side effects, satisfaction, and continuation of CAB-LA PrEP and contraceptive methods will also be evaluated.

Evaluation of Multiple Interventions to Improve HIV Treatment Outcomes Among People Who Inject Drugs in India
The goal of this study is to improve HIV care outcomes for people who inject drugs (PWID) in India. The study will implement a two-phase trial to evaluate whether HIV treatment outcomes (HIV viral suppression) in HIV infected PWID can be improved with three different interventions: i) by offering a faster treatment start time (same-day antiretroviral therapy \[ART\] initiation vs. standard), ii) by provided community-based HIV care in PWID-focused centers (vs. centralized government-based HIV care) and, iii) providing an enhanced adherence support to participants who experience treatment failure at six months (vs. routine adherence support). The investigators hypothesize that faster access to ART and HIV treatment in PWID-focused community sites will lead to higher levels of initiation and retention to ART compared with standard care; and use of enhanced navigation and psychosocial support to patients who experience treatment failure at six months will lead to improved viral suppression compared with routine adherence support.

Dasatinib for HIV-1 Reservoir Reduction
This study will test if the medicine dasatinib can lower the hidden amount of HIV in the body, called the HIV "reservoir." It will also check if dasatinib is safe and easy to take for people living with HIV who have a suppressed viral load while on antiretroviral therapy (ART). Adults 18 years or older who have been on ART for at least 48 months and have had a suppressed HIV-1 viral load for at least 36 months may be able to join. People will be randomly assigned to take dasatinib 100 mg by mouth once a day or a look-alike substance with no drug, called a placebo, for 12 weeks. Neither participants nor researchers will know who gets which (double-blind). The study team will do regular health checks and blood tests to track safety, tolerability, the HIV reservoir, and changes in immune cells. The study lasts 36 weeks total: 12 weeks of treatment and 24 weeks of follow-up, with clinic visits and possible phone calls. Fourteen people will take part; eight will get dasatinib and six will get placebo. Dasatinib may lower the HIV reservoir, but this is not guaranteed. All medicines can cause side effects, called adverse events (AE). The study team will watch closely and provide medical support. Joining is your choice, and you can leave at any time. If you leave, the team will talk with you about next steps for your care.

Doxi-Rio: Study on the Use of Doxycycline to Prevent Sexually Transmitted Infections in Rio de Janeiro
The goal of this clinical trial is to learn if doxycycline post-exposure prophylaxis (doxy-PEP) can help prevent bacterial sexually transmitted infections (STIs) among sexual and gender minorities in Rio de Janeiro, Brazil, including men who have sex with men, transgender women, and travestis who are living with HIV or using HIV pre-exposure prophylaxis (PrEP). Bacterial STIs such as syphilis, gonorrhea, and chlamydia remain common in these populations, even with existing prevention strategies. This study aims to answer the following questions: whether doxy-PEP can reduce the number of new STIs, whether it is safe and well tolerated, whether participants use it as recommended, and whether its use may contribute to antibiotic resistance or changes in the body's natural bacteria. Doxy-PEP involves taking a dose of doxycycline, an antibiotic, shortly after sexual activity to reduce the risk of acquiring STIs. Participants will first receive information and counseling about doxy-PEP, including its possible benefits and risks, and will then choose whether or not to use this prevention strategy. Those who choose to use doxy-PEP will take doxycycline after sex as instructed and will be followed for up to 48 weeks, with clinic visits approximately every three months. During these visits, participants will be tested for STIs, monitored for side effects, and asked about medication use, sexual health, and overall well-being. Researchers will collect information on new STI diagnoses, safety, and how consistently participants use doxy-PEP. The study will also explore participants' experiences and perceptions of this strategy. The results of this study will help determine whether doxy-PEP is a practical and acceptable approach for STI prevention in Brazil and may inform future public health strategies.

Cardiovascular Responses to Exercise in People Living With HIV/AIDS: Effects of Exercise Training
Patients living with HIV (PLWHIV) have compromised muscle metaboreflex, which can cause exercise intolerance. This randomized controlled clinical trial will verify the effects of regular exercise on autonomic and hemodynamic responses to muscle ergoreflex activation in these patients. PLWHIV without regular physical exercise will be randomly assigned into an exercise training or a control group. The exercise training group will undergo regular physical exercise during 12 weeks (60-min session performed 3 times/wk with moderate intensity), while the control group will keep inactive. Another group consisted of inactive HIV-uninfected group will be included. The primary endpoints will be blood pressure and autonomic markers in response to the Stroop Color-Word Test and the activation of muscle ergoreflex, by means of the post-exercise circulatory arrest (PECA), which will be performed with and without the topical application of a capsaicin-based analgesic balm. Secondary endpoints will include heart rate, peripheral vascular resistance, stroke volume, cardiac output, blood lactate concentration, anthropometrics, and handgrip strength. The active and inactive PLWHIV groups will be evaluated before and after the exercise training, while the healthy group only at baseline.

Study to Evaluate the Efficacy, Safety, and Tolerability of Long-acting Intramuscular Cabotegravir and Rilpivirine for Maintenance of Virologic Suppression Following Switch From an Integrase Inhibitor in HIV-1 Infected Therapy Naive Participants
The First Long-Acting Injectable Regimen (FLAIR) study is being conducted to establish if human immunodeficiency virus type-1 (HIV-1) infected adult participants whose virus is virologically suppressed on an integrase inhibitor single tablet regimen (INI STR) will remain suppressed after switching to a two-drug intramuscular (IM) long-acting (LA) regimen of cabotegravir (CAB) and rilpivirine (RPV). In this study, the INI STR will be limited to abacavir/dolutegravir/lamivudine (ABC/DTG/3TC). FLAIR is a Phase 3, multi-phase, randomized, open label, active-controlled, multicenter, parallel-group, non-inferiority study in HIV-1, anti-retroviral therapy (ART)-naïve adult participants. This study is designed to demonstrate the non-inferior antiviral activity of switching to a two drug CAB LA 400 mg + RPV LA 600 mg regimen every 4 weeks (Q4W: monthly) compared to remaining on ABC/DTG/3TC over 48 weeks (4 weeks oral CAB + RPV, 44 weeks LA therapy). Participants who are HLA-B\*5701 positive at Screening may enroll into the study and receive DTG plus a non-abacavir containing dual nucleoside reverse transcriptase inhibitor (NRTI) regimen. Eligible participants will enroll into the Induction Phase of the study and receive ABC/DTG/3TC for 20 weeks (Week \[-20\] to Day 1). Participants who have an HIV 1 ribose nucleic acid (RNA) \<50 copies per milliliter (c/mL) at Week (-4) will be randomized (1:1) into the Maintenance Phase at Day 1 to either continue ABC/DTG/3TC or to discontinue ABC/DTG/3TC and begin oral therapy with CAB 30 mg + RPV 25 mg once daily for approximately 4 Weeks, followed by monthly CAB LA + RPV LA injections from visit Week 4b until study completion or withdrawal. Participants who successfully complete Week 100 (without meeting study defined withdrawal criteria and who remain virologically suppressed through Week 96: HIV-1 RNA \<50 c/mL) will be given the option to switch to the LA arm in the Extension Phase (using an optional oral lead-in with CAB + RPV) or be withdrawn from the study. Participants will continue to receive injections every 4 weeks during the Extension Phase until CAB LA and RPV LA are either locally approved and commercially available, the participant no longer derives clinical benefit, the participant meets a protocol-defined reason for discontinuation, or until development of either CAB LA or RPV LA is terminated.
