Researchers are evaluating the use of XYOSTED as a testosterone replacement therapy in adolescent males aged 12 to under 18 years with primary or secondary hypogonadism, a condition where the body produces little or no testosterone. This Phase 34 open-label study aims to assess how well XYOSTED supports the continuation or start of puberty, along with its safety and the testosterone levels it maintains. Participants will receive XYOSTED injections at doses tailored to their weight and targeted pubertal stage. Dose adjustments will be made based on testosterone levels measured at specific intervals after dosing, with evaluations approximately every three months to reach the desired hormone levels. After completing the 52-week initial study period, participants may enter a 24-month extension to further monitor long-term safety and treatment effects. Throughout the study and extension, participants will undergo clinical examinations including pubertal staging, blood tests for testosterone and other labs, bone density scans, body composition assessments, and X-rays to monitor bone age. Researchers will track changes in puberty progression, bone health, body measurements, and hormone levels. Participants will attend regular clinic visits every six months during the extension phase to continue safety and pharmacokinetic evaluations.

Researchers are evaluating the safety and effects of a medicine called Ritlecitinib for adults with moderate to severe hidradenitis suppurativa HS, a condition that causes long-lasting painful red lumps on the skin. The study focuses on participants who have not responded well to or cannot tolerate antibiotics for HS. This Phase 2, randomized, double-blind, placebo-controlled study aims to understand how Ritlecitinib compares to placebo in treating this condition. Participants will be randomly assigned to take either Ritlecitinib or a matching placebo by mouth once daily at home. The study includes a loading dose of Ritlecitinib for the first 8 weeks, followed by a maintenance dose for the next 8 weeks, totaling 16 weeks of treatment. The placebo group will follow the same schedule with a pill that looks like the study medicine but contains no active drug. Throughout the study, participants will have about 10 clinic visits over approximately 24 weeks, including screening, Day 1, and follow-ups every 1, 2, or 4 weeks until Week 16. At these visits, health status will be reviewed through physical exams, blood and urine tests, vital signs, chest X-rays, ECGs, hearing tests, and questionnaires. Participants will also record daily medication intake and HS symptoms using a mobile eDiary. Researchers will measure skin response and safety outcomes to assess the effects of the study medicine compared to placebo.

Researchers are evaluating new medicines to prevent HIV-1 Human Immunodeficiency Virus Type 1 infection. This Phase 3 clinical study aims to determine if taking the drug MK-8527 once a month can prevent HIV-1 infection as well as or better than the standard daily pre-exposure prophylaxis PrEP. The study also assesses the safety and tolerance of MK-8527 in participants. Participants are randomly assigned to one of two groups. One group receives 11 mg of MK-8527 once monthly along with a daily placebo pill matching FTCTDF. The other group receives a daily dose of FTC245 mg TDF and a monthly placebo matching MK-8527. This treatment period lasts for approximately two years, followed by an additional 28-day period where all participants receive open-label FTCTDF daily. During the study, participants will undergo regular monitoring to check for HIV-1 infection and any adverse events. Researchers will track the number of participants who acquire HIV-1, experience side effects, or stop treatment due to side effects over the two-year period. Safety and adherence assessments will be conducted to evaluate the study treatments. The total participation time includes the two-year treatment phase plus the 28-day follow-up with open-label FTCTDF.

Researchers are evaluating molnupiravir, an oral medicine designed to stop the COVID-19 virus from multiplying, to see if it can prevent severe illness from COVID-19 in people at high risk of disease progression. The study focuses on adults with confirmed COVID-19 infection who are at increased risk due to age, medical conditions, or other factors. This is a Phase 3 randomized, placebo-controlled, double-blind clinical trial led by Merck Sharp & Dohme LLC. Participants will be randomly assigned to receive either molnupiravir or a matching placebo. Those in the molnupiravir group will take 800 mg orally every 12 hours for 5 days, totaling 10 doses. The same dosing schedule applies to the placebo group. Some participants may also receive remdesivir as part of standard care if clinically appropriate. During the study, participants will be monitored for up to 29 days to assess outcomes such as hospitalization, death, or medically attended visits related to COVID-19. Safety will be evaluated by tracking adverse events and discontinuation due to side effects. Researchers will also measure symptom relief, viral RNA levels, and other health indicators. The study is expected to continue until January 2031.

Researchers are evaluating the long-term safety, tolerability, and lasting effects of ALKS 2680 tablets in adults with Narcolepsy Type 1, Narcolepsy Type 2, or Idiopathic Hypersomnia. This study is an open-label extension designed to continue monitoring participants who completed earlier ALKS 2680 parent studies, focusing on treatment durability and adverse events over an extended period. Participants receive ALKS 2680 oral tablets in doses ranging from 4 mg to 18 mg once daily. The study includes groups with Narcolepsy Type 1, Narcolepsy Type 2, and Idiopathic Hypersomnia. Treatment effects and safety are observed for up to 100 weeks, with dosing adjusted as needed. The study follows a non-randomized, open-label design without blinding. During the study, participants undergo regular assessments including monitoring of treatment-emergent adverse events, measurement of sleep latency using the Maintenance of Wakefulness Test, and evaluation of daytime sleepiness via the Epworth Sleepiness Scale. The total participation duration extends up to approximately 100 weeks, with safety, tolerability, and treatment effects closely tracked throughout this period.

Researchers are evaluating whether retatrutide and tirzepatide can prevent major adverse liver outcomes in adults with metabolic dysfunction-associated steatotic liver disease MASLD who are at high risk based on non-invasive tests. This Phase 3 randomized controlled trial aims to assess these treatments compared to placebo in about 4,500 adults over approximately 224 weeks. The study is sponsored by Eli Lilly and Company and focuses on liver disease progression and related health measures. Participants will be randomly assigned to receive retatrutide, tirzepatide, or placebo, all administered by subcutaneous injection. The trial includes two placebo groups corresponding to each experimental drug. After completing the main study, eligible participants may join a 2-year extension where all will receive either retatrutide or tirzepatide regardless of their initial assignment. During the study, participants may attend around 25 to 30 clinic visits for health monitoring, study procedures, and assessments of liver function and disease status. Researchers will measure the time to major adverse liver outcomes, changes in liver fibrosis scores, liver stiffness, liver fat content, liver enzyme levels, body weight, and cardiovascular events. Monitoring will continue from baseline through study completion, with detailed evaluations at multiple timepoints including week 104.

This trial investigates MZE829 capsules in adults with proteinuric chronic kidney disease who also carry the APOL1 high risk genotype, specifically G1G1, G2G2, or G1G2 variants. The study aims to evaluate the safety, tolerability, and impact on albuminuria, a marker of kidney damage, in this population. It is an open-label Phase 2 trial, meaning all participants receive the study drug and results will help determine its effects and safety profile. Participants receive MZE829 capsules orally in a single-group design. The study includes two cohorts one with chronic kidney disease alongside diabetes, and another with chronic kidney disease without diabetes. The treatment and monitoring occur over a 12-week period, during which the study team assesses drug safety and effects on albuminuria levels. During the trial, participants will be monitored for adverse events and tolerability from baseline through week 12. Researchers will also measure changes in urine albumin-to-creatinine ratio UACR to evaluate kidney function. Blood samples will be taken to assess plasma drug concentrations. The total participation time is approximately 12 weeks, focusing on safety and biological effects of MZE829.

This research aims to evaluate the effects of different doses of vosoritide and compare the therapeutic dose of vosoritide to human growth hormone hGH in children diagnosed with idiopathic short stature ISS. The study is a Phase 2, randomized, controlled trial that seeks to understand how these treatments influence growth in affected children. Participants will first undergo a minimum 6-month observation period to assess their baseline growth. Then, those assigned to the vosoritide and placebo groups will receive randomized treatment for at least 6 months, with placebo limited to a maximum of 6 months. After this, open-label vosoritide treatment will continue until participants reach near-final adult height or at least 16 years for females and 18 years for males, whichever is later. Participants randomized to the hGH group will receive open-label hGH treatment for a minimum of 4 years. Study treatments involve daily injections. Throughout the study, participants will attend regular visits for clinical and imaging assessments, including evaluations of hips and lower extremities. Researchers will monitor safety concerns such as hypotension, fractures, and slipped capital femoral epiphysis, with oversight from an independent Data Monitoring Committee. The main outcomes measured include changes in annualized growth velocity at 6 months and height changes over 4 years. Follow-up assessments will continue as needed, including safety monitoring, until study completion, which could last up to 15 years.
