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 effects of an investigational medicine called PGN-EDODM1 to understand how safe and tolerable multiple doses are for adults with myotonic dystrophy type 1 DM1. This phase 2 study compares PGN-EDODM1 to a placebo to assess its safety and tolerability in people with this condition. Participants will be randomly assigned to receive either PGN-EDODM1 or a placebo. The treatment is given by intravenous infusion once every 4 weeks for a total of 12 weeks. Those in the PGN-EDODM1 group will receive ascending doses, while the placebo group will receive saline infusions on the same schedule. During the study, participants will be monitored for safety by tracking adverse events from the start through Day 112. Researchers will measure drug levels in the blood, changes in muscle tissue, myotonia severity, hand grip strength, and mobility using specific tests. The total participation lasts through about 16 weeks, including treatment and follow-up assessments.

Researchers are evaluating the safety, tolerability, pharmacokinetics PK, pharmacodynamics PD, and efficacy of NS101, an anti-FAM19A5 antibody, in both healthy volunteers and patients with sudden sensorineural hearing loss SSNHL. This exploratory Phase 1b2a study aims to determine if multiple doses of NS101 are safe and tolerable and whether the treatment can help restore hearing in SSNHL patients who have not sufficiently improved after standard steroid therapy. The study includes a placebo control and uses a double-blind design to ensure unbiased results. Participants receive NS101 or placebo via intravenous infusion at doses of 15 mgkg or 30 mgkg administered every two weeks. Healthy volunteers receive treatment for 6 weeks, whereas SSNHL patients receive treatment for 12 weeks. The study has four groups two dose levels for healthy volunteers with active and placebo arms, and two groups for SSNHL patients receiving either NS101 or placebo. Treatments are given systematically, and participants are randomly assigned to the groups. Throughout the study, participants undergo frequent safety assessments to monitor changes from baseline at multiple time points, including days and weeks after treatment begins. Pharmacokinetic and immunological tests are also performed to track how the drug behaves in the body and its effects. Researchers measure hearing improvement and monitor tolerability closely. The study is expected to continue until January 2027, with participants involved in regular visits and evaluations during and after treatment.

Researchers are evaluating a new medication called VH4524184 for treating adults with HIV-1 who have never received treatment before. This Phase 2b study compares two doses of VH4524184, each taken with the medications emtricitabine and tenofovir alafenamide FTCTAF, against a standard HIV treatment combining dolutegravir and lamivudine DTG3TC. The goal is to collect long-term data on the antiviral activity of VH4524184 and to understand the best dosing for future studies. Participants are assigned to one of several groups one group receives a low dose of VH4524184 plus FTCTAF daily for 12 months, another group receives a high dose of VH4524184 plus FTCTAF daily for 12 months, and a third group takes DTG and 3TC daily for 24 months. After 12 months, those on VH4524184 may continue with a selected dose combined with FTCTAF daily until month 24. All medications are taken orally. During the study, participants attend scheduled visits for assessments including blood tests to measure HIV-1 RNA levels, CD4 T-cell counts, and drug concentrations. Researchers monitor the percentage of participants achieving viral suppression at 12 months and maintain it through 24 months. Safety is closely observed through tracking adverse events until roughly month 36. The total participation time may span up to 36 months to evaluate the long-term effects and safety of the treatments.

Researchers are evaluating Dostarlimab compared to a placebo in adults with locally advanced unresected Head and Neck Squamous Cell Carcinoma HNSCC. This phase 3 trial aims to assess the safety and effectiveness of Dostarlimab as a sequential therapy following chemoradiation treatment in participants with this type of cancer. Participants are randomly assigned to receive either Dostarlimab or a placebo, both given as intravenous infusions. The study is double-blind, meaning neither the participants nor the researchers know which treatment is being given. The treatments follow completion of chemoradiation with cisplatin and radiotherapy intended to cure the cancer. During the study, participants will be monitored for up to approximately 5 years. Researchers will evaluate event-free survival and overall survival, with safety assessments including treatment-emergent adverse events and laboratory tests. Blood samples will be taken to measure drug levels and immune responses. This long-term follow-up will help understand the effects and safety of Dostarlimab after chemoradiation therapy.

Researchers are studying the effectiveness and safety of lebrikizumab in people aged 12 and older who have chronic rhinosinusitis with nasal polyps and are treated with intranasal corticosteroids. This Phase 3 trial compares different dosing schedules of lebrikizumab with a placebo to find out how well it reduces symptoms such as nasal congestion and polyp size over about 18 months. Participants receive lebrikizumab or placebo as subcutaneous injections while continuing their regular intranasal corticosteroid therapy. Adolescents aged 12 to under 18 weighing at least 40 kg will receive open-label lebrikizumab every 2 or 4 weeks. The study includes two experimental lebrikizumab groups with different dosing intervals and a placebo group, all alongside background intranasal corticosteroids. During the study, participants will have regular assessments including symptom severity scores, nasal polyp size measured by endoscopy, sinus imaging, lung function tests, and questionnaires about nasal symptoms and quality of life. Researchers will monitor changes from baseline to week 24 primarily for nasal congestion and polyp scores. Safety and long-term effects will also be observed throughout the study duration of about 18 months.

Researchers are evaluating the efficacy and safety of opevesostat combined with daily corticosteroids compared to alternative treatments abiraterone acetate or enzalutamide in participants with metastatic castration-resistant prostate cancer mCRPC who have previously been treated with one next-generation hormonal agent NHA. The study aims to determine if opevesostat offers better control of disease progression assessed by radiographic progression-free survival, including participants with and without androgen receptor ligand binding domain mutations. Overall survival has also been included as a secondary outcome measure. Participants are randomly assigned to one of two groups. One group receives opevesostat 5 mg orally twice daily, plus dexamethasone 1.5 mg and fludrocortisone acetate 0.1 mg orally once daily, continuing until disease progression. Hydrocortisone is available as a rescue medication if needed. The other group receives either abiraterone 1000 mg once daily with prednisone 5 mg twice daily or enzalutamide 160 mg once daily, also until disease progression. This open-label, phase 3 study compares these two treatment approaches in a parallel design. During the study, participants undergo regular assessments including imaging scans to measure disease progression, safety monitoring, and evaluations of overall survival and quality of life. Researchers track radiographic progression-free survival for up to 52 months and secondary outcomes such as overall survival, time to new treatments, pain progression, and prostate-specific antigen PSA responses for up to approximately 82 months. Participants are closely monitored for adverse events and treatment tolerability throughout the study duration, which spans several years.

Researchers are evaluating REGN5093 for treating advanced Non-Small Cell Lung Cancer NSCLC with MET alteration. The study aims to determine the safety, tolerability, and effectiveness of REGN5093. The trial includes two phases Phase 1 focuses on finding a safe dose of REGN5093, and Phase 2 uses that dose to assess how well REGN5093 shrinks tumors and affects cancer progression. Participants will receive REGN5093 through intravenous infusion. The study starts with dose escalation cohorts in Phase 1, followed by an expansion phase in Phase 2. The treatment is given as a monotherapy, and dosing schedules are designed to find an appropriate and safe dose and then evaluate its impact on the disease. During the study, participants will be closely monitored for side effects, blood levels of REGN5093, and tumor response using RECIST 1.1 criteria. Researchers will record safety data, including treatment-emergent adverse events and serious adverse events, over an average of 12 years. Outcomes like objective response rate, duration of response, disease control rate, progression-free survival, and overall survival will be measured to understand the long-term effects and safety of REGN5093.

Safety is closely tracked with various assessments until about week 42.

This research aims to evaluate the effectiveness and safety of plixorafenib in participants with cancers that have specific BRAF gene alterations. These include locally advanced or metastatic solid tumors, primary central nervous system tumors, and rare BRAF V600E-mutated solid tumors such as anaplastic thyroid, ovarian, and cholangiocarcinoma cancers. The study focuses on participants with BRAF V600E mutations or BRAF fusions and seeks to understand treatment effects across various cancer types. Participants receive plixorafenib orally in continuous 3-week cycles. Dosing may be increased as tolerated and continues until disease progression, unacceptable side effects, or withdrawal for other reasons. The study includes different subprotocols tailored to tumor type and BRAF alteration, such as unresectable solid tumors with BRAF fusions, recurrent primary CNS tumors with BRAF V600E mutations, rare non-CNS solid tumors with BRAF V600E mutations, and other advanced solid tumors with BRAF V600E mutations. Participants will undergo scans before starting treatment to assess tumor changes, and regular monitoring will continue during treatment. Researchers will evaluate tumor response, progression-free survival, overall survival, treatment safety, and drug levels in the blood over up to approximately four years. The study tracks side effects and collects detailed pharmacokinetic data to understand how the drug is processed. Participants remain in the study until disease progression or other withdrawal criteria are met, with ongoing safety and efficacy assessments.
