Researchers are investigating the effects of XYOSTED as a testosterone replacement therapy in adolescent males aged 12 to under 18 years who have primary or secondary hypogonadism. This Phase 3/4, open-label, multicenter study aims to evaluate how well XYOSTED supports puberty continuation or induction, as well as its dosage, safety, and testosterone level outcomes. Participants have a confirmed deficiency or absence of endogenous testosterone and will be assessed for pubertal development and hormone levels before starting treatment. Participants will receive XYOSTED injections with dosages tailored to their weight and targeted Tanner Stage of puberty. Dose adjustments will be made regularly based on serum total testosterone levels measured at specific intervals after dosing, with evaluations approximately every three months to reach desired testosterone levels. After completing the 52-week primary study, participants may join a 24-month long-term safety extension with clinic visits every six months for ongoing clinical, laboratory, and pharmacokinetic assessments. During the study, participants will undergo thorough clinical examinations including pubertal staging, multiple testosterone measurements, and monitoring for safety and pharmacokinetics throughout treatment and extension periods. Researchers will track changes in testosterone levels from enrollment through week 53 and monitor overall safety. The study includes detailed follow-up and dose management to support pubertal development and assess long-term effects of XYOSTED therapy in this population.

Researchers are assessing the safety and effects of Ritlecitinib, a study medicine, for treating hidradenitis suppurativa (HS), a condition causing long-lasting, painful red skin lumps. This phase 2 study focuses on adults with moderate to severe HS who have not responded well to or cannot tolerate antibiotics. The goal is to compare experiences and outcomes between those receiving Ritlecitinib and those receiving a placebo. Participants will be randomly assigned to take either Ritlecitinib or a placebo pill once daily at home. The treatment involves an initial loading dose of Ritlecitinib for 8 weeks, followed by an 8-week maintenance dose, totaling 16 weeks of treatment. The placebo group will receive a matching pill with no active medicine. Over approximately 24 weeks, including screening and follow-up, participants will attend around 10 clinic visits for health evaluations, including physical exams, blood and urine tests, vital signs, chest X-rays, ECGs, hearing tests, and questionnaires. They will also track their medication intake and HS symptoms daily using an electronic diary on a mobile phone. The study will measure how many patients achieve at least a 50% improvement in HS symptoms by week 16 to evaluate treatment response and safety.

Researchers are looking for new medicines to prevent HIV-1 (Human Immunodeficiency Virus Type 1) infection. The goals of this study are to learn: * If taking MK-8527 once a month works to prevent HIV-1 infection as well as or better than a standard (usual) pre-exposure prophylaxis (PrEP) taken once a day * About the safety of MK-8527 and if people tolerate it

Researchers are evaluating molnupiravir, a study medicine designed to stop the COVID-19 virus from multiplying, to see if it can prevent severe illness from COVID-19 more effectively than a placebo. This Phase 3 randomized, placebo-controlled, double-blind study focuses on non-hospitalized adults at high risk of severe disease progression due to COVID-19. The study addresses the need for alternative treatments for people who cannot take certain COVID-19 medications due to availability or potential drug interactions. Participants will receive either molnupiravir or a placebo, both given orally as two 400 mg film-coated tablets every 12 hours for 5 days, totaling 10 doses. Some participants may also receive remdesivir as part of standard care if clinically appropriate and available. The study compares the effects of molnupiravir with placebo in preventing severe illness outcomes. Throughout the study, participants will be monitored for outcomes such as hospitalization, death, or medically attended visits related to COVID-19 up to 29 days. Safety is assessed by tracking adverse events for up to about 5 months and discontinuation of study treatment due to adverse events for about 5 days. The study involves laboratory tests, symptom assessments, and safety evaluations to understand molnupiravir's impact on disease progression and participant health.

Researchers are evaluating the long-term safety, tolerability, and lasting effects of ALKS 2680 tablets in adults aged 18 to 70 years with Narcolepsy Type 1, Narcolepsy Type 2, or Idiopathic Hypersomnia. This study continues from earlier trials and aims to monitor how well the treatment works and how safe it is over an extended period. Participants receive daily oral doses of ALKS 2680 tablets in varying strengths ranging from 4 mg to 18 mg. The study is an open-label, long-term extension, meaning all participants know they are receiving ALKS 2680 as they continue treatment after completing a prior parent study. The dose is administered once daily, and the study focuses on ongoing monitoring rather than comparing to a placebo. During the study, participants are regularly assessed for any treatment-emergent adverse events up to 100 weeks. Safety evaluations include clinical assessments, laboratory tests, and monitoring for any new health issues. Researchers track the ability to tolerate the medication and the durability of its effect on symptoms. This long-term follow-up helps ensure comprehensive understanding of the treatment's impact over time.

Researchers are evaluating whether the drugs retatrutide and tirzepatide can prevent major adverse liver outcomes (MALO) in adults with metabolic dysfunction-associated steatotic liver disease (MASLD) who are at high risk. This Phase 3 trial enrolls about 4,500 adults with MASLD identified by non-invasive tests indicating an increased likelihood of developing serious liver problems. The study aims to understand how these treatments might affect liver health over time compared to a placebo. Participants will be randomly assigned to receive either retatrutide, tirzepatide, or a placebo, all given by subcutaneous injection. The study will last approximately 224 weeks, during which participants may attend 25 to 30 clinic visits for monitoring and assessment. After the main study, eligible participants can join an optional 2-year extension where all will receive either retatrutide or tirzepatide regardless of their original group. Throughout the trial, participants’ liver function and disease progression will be closely monitored through various health assessments. Researchers will track the time to the first major adverse liver event as the main outcome. Safety and health status will be evaluated regularly during clinic visits, ensuring thorough observation over the long study period.

This research aims to evaluate the safety, tolerability, and impact on albuminuria of the drug MZE829 in adults who have proteinuric chronic kidney disease and carry the APOL1 high-risk genotype. This Phase 2 open-label study focuses on participants with specific genetic markers associated with kidney disease to better understand treatment effects. Participants will receive MZE829 in the form of oral capsules. The study involves monitoring the participants over a 12-week period to assess the drug's safety and how well patients tolerate it. Researchers will also measure changes in albuminuria, which reflects kidney function. During the study, participants will be closely monitored for any adverse events from the first day through week 12. Safety assessments and laboratory tests will be performed to track the drug’s effects. The main goal is to determine how safe and tolerable MZE829 is, along with its impact on kidney disease markers over the treatment duration.

Researchers are investigating the effects of multiple doses of vosoritide and comparing its therapeutic dose to human growth hormone (hGH) in children with idiopathic short stature (ISS). This Phase 2 study aims to understand how these treatments influence growth in this population. After an initial observation period of at least 6 months to measure baseline growth, participants are randomly assigned to receive either vosoritide, placebo, or hGH (the latter only in the United States). Those in the vosoritide and placebo groups undergo up to 6 months of randomized treatment, followed by open-label vosoritide until they reach near-final adult height or at least age 16 for females or 18 for males. Participants assigned to hGH receive open-label treatment for a minimum of 4 years. Throughout the study, safety is carefully monitored with clinical and imaging assessments focused on hips and lower extremities, as well as watching for hypotension, fractures, and slipped capital femoral epiphysis. An independent Data Monitoring Committee reviews safety data regularly. Study visits include a treatment completion visit about 4 weeks after the last dose, and follow-up assessments may continue annually through the end of the study. Key outcome measures include changes in annualized growth velocity at 6 months and changes in height and height Z-score after 4 years.

Researchers are evaluating the safety and effectiveness of two combined treatments, KarXT and KarX-EC, for adults aged 55 to 90 who experience agitation related to Alzheimer's Disease. This Phase 3, randomized, double-blind, placebo-controlled study aims to better understand how these treatments may help reduce agitation symptoms in this population while monitoring safety. Participants will receive either the active drugs Xanomeline/Trospium Chloride Capsule and Xanomeline Enteric Capsule or a placebo, taken at specified doses on designated days. The study is carefully designed to compare these treatments against placebo to evaluate their impact on agitation symptoms associated with Alzheimer's Disease. During the study, participants will be assessed using the Cohen-Mansfield Agitation Inventory-International Psychogeriatric Association (CMAI-IPA) total score to measure changes from baseline at Week 14. Caregivers will be involved to help monitor compliance and report participant status throughout the study. Safety and efficacy will be closely monitored during this 14-week period to gather detailed information about treatment outcomes.

Researchers are investigating the effectiveness, safety, and tolerability of combining baxdrostat with dapagliflozin compared to dapagliflozin alone in people with chronic kidney disease (CKD) and high blood pressure. This Phase III, international, multicenter, double-blind, placebo-controlled study aims to see if this combination reduces risks such as significant kidney function decline, kidney failure, heart failure events, or cardiovascular death. The study includes a 4-week run-in period where participants not previously treated with SGLT2 inhibitors receive dapagliflozin alone. After this, participants are randomly assigned to receive either baxdrostat plus dapagliflozin or placebo plus dapagliflozin in a double-blinded manner. Study visits occur frequently initially (at 2, 4, 8, 16, 34, and 52 weeks after randomization) and then approximately every 4 months. If participants stop the blinded treatment early, they continue dapagliflozin alone unless specific criteria require its discontinuation. Participants will undergo regular assessments including blood pressure monitoring and laboratory tests related to kidney function and cardiovascular health. The primary outcome measures the reduction in risk of major kidney and heart events over up to 37 months. Even if participants stop the study treatment, they will continue follow-up visits and data collection to ensure comprehensive safety and efficacy evaluation throughout the study duration.
