Researchers are evaluating new medicines to prevent Human Immunodeficiency Virus Type 1 (HIV-1) infection, focusing on women assigned female at birth who are cisgender. This Phase 3 clinical trial aims to determine whether taking the drug MK-8527 once a month is more effective than the usual daily pre-exposure prophylaxis (PrEP) medication in preventing HIV-1 infection. The study also seeks to understand the safety and tolerability of MK-8527 in this population. Participants will be randomly assigned to receive one of several oral tablets: MK-8527 once monthly, a standard daily PrEP medication called Emtricitabine/tenofovir disoproxil (FTC/TDF), or placebo tablets matched to each drug. This double-blind study compares these groups to assess both the effectiveness and side effects of MK-8527 over time. During the study, participants will be monitored for up to about two years to track new HIV-1 infections, any adverse events they experience, and whether they stop taking the study medication due to side effects. Researchers will regularly evaluate participants' health, safety, and adherence to the treatment plan throughout this period.

Researchers are conducting a global observational study to better understand acute infections in adults who are hospitalized. This study aims to gather important information on risk factors, clinical signs, disease mechanisms, and management strategies for various infectious diseases, including respiratory infections, infections outside the respiratory tract, established infectious diseases, and emerging infections. The data collected will help guide the selection of treatments and the design of future clinical trials. Participants in this study will not receive any intervention as it is purely observational. The study involves collecting data and biological samples from participants across multiple sites worldwide. It focuses on adults admitted to the hospital, or emergency department with expected admission, due to suspected or confirmed acute infections with symptom onset within the past 30 days. The study is designed to build a comprehensive understanding of acute infectious diseases shortly after their emergence. Participants will be monitored during their hospital stay, with researchers collecting clinical data and biospecimens to characterize the infection. The study measures various outcomes including mortality at day 28, days to recovery, time to sustained recovery, clinical improvement by day 7, organ support-free days, and organ failure scores at day 28. This continuous monitoring will help to establish early knowledge about infectious diseases and inform future trials and management approaches.

Researchers are evaluating the long-term use of a long-acting injectable drug called cabotegravir (CAB LA) for HIV pre-exposure prophylaxis (PrEP) in people at risk of acquiring HIV. This study focuses on participants who have completed or are currently enrolled in previous related studies HPTN 083 and HPTN 084 and their sub-studies. The goal is to monitor new HIV infections, serious adverse events, injection site reactions, and other adverse events that might cause withdrawal over an extended period. Participants will receive CAB LA by gluteal intramuscular injection at a dose of 600 mg every 8 weeks. This treatment continues from the parent studies, and participants will be followed for up to approximately 3 years. The study includes ongoing treatment with CAB LA and regular assessments to evaluate safety and effectiveness as part of this long-term follow-up. During the study, participants will undergo regular HIV testing, safety monitoring, and evaluation of injection site reactions and adverse events. Researchers will track the number of new HIV infections and detailed characteristics of these infections from the start of the study through the follow-up period. This includes monitoring serious and grade 3 or 4 injection site reactions, as well as other adverse events that may lead to withdrawal from the study. Participants will be observed closely to ensure continued safety throughout the study duration.

Researchers are evaluating the safety and effectiveness of a single infusion of anti-COVID-19 hyperimmune intravenous immunoglobulin (hIVIG) compared to a placebo in adults recently diagnosed with SARS-CoV-2 infection who do not need hospitalization. This Phase 3, double-blind, randomized trial aims to assess participants' clinical status seven days after treatment using a five-category scale ranging from no symptoms to critical illness or death. The study also examines outcomes in two groups: those receiving other approved antiviral treatments and those who are not. Participants receive either a single 3.5-gram infusion of hIVIG or a 35-milliliter infusion of saline placebo, with equal chance of assignment to each group. The randomization is stratified by study site and whether participants are receiving standard antiviral care. The infusion occurs once, and participants are monitored thereafter to compare the effects of hIVIG plus standard care versus placebo plus standard care. During the study, participants provide written consent and agree to follow study procedures through 28 days. Researchers assess clinical status seven days after infusion and track safety and disease progression. The study excludes those with prior immune therapies or certain medical conditions and requires participants to avoid other COVID-19 treatment trials through Day 7 unless hospitalized or experiencing significant disease worsening. Clinical assessments and monitoring continue to ensure participant safety and capture outcomes related to COVID-19 illness severity.
