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 disitamab vedotin alone or combined with pembrolizumab to treat urothelial cancer that expresses HER2. This study focuses on participants with locally advanced or metastatic urothelial cancer that cannot be removed by surgery. It aims to assess how well the drug works and to monitor the side effects experienced by participants. Participants receive disitamab vedotin intravenously every 2 weeks, either alone or with pembrolizumab given by intravenous infusion on Day 1 of each 6-week cycle. The study includes multiple cohorts receiving different combinations or monotherapy treatments. The treatment period and monitoring last approximately 2 years, with ongoing assessments of drug effects and safety. During the study, participants undergo regular evaluations including imaging scans to measure tumor response, laboratory tests, electrocardiograms to monitor heart function, and assessments of side effects. Researchers measure treatment response using established cancer evaluation criteria and track survival and disease control over about 3 years. Participants are closely monitored for adverse effects and blood levels of the drugs to understand how the treatments behave in the body.

Researchers are comparing the rates of surgical and minimally invasive interventions, as well as any harms, in Medicare beneficiaries treated with the MILD procedure versus those treated with interspinous process decompression IPD for lumbar spinal stenosis with neurogenic claudication. This observational study uses Medicare claims data to follow patients for 24 months after their initial procedure starting from January 1, 2017. The purpose is to evaluate outcomes between these two types of procedures without requiring prior patient enrollment or consent. The study includes two groups patients who received MILD, which is a percutaneous image-guided lumbar decompression performed under fluoroscopic guidance through a dorsal approach to the spine, and patients who received IPD, a different device-based decompression procedure. Data on reoperations and complications will be collected for both groups over a 24-month follow-up period using Medicare claims. Enrollment continues until the sponsor decides to stop. Participants involvement is passive as the study uses existing Medicare claims data. Researchers will monitor rates of harms related to the initial procedure and subsequent surgical or minimally invasive interventions over two years. No direct patient visits or interventions are conducted, and the study is exempt from institutional review board oversight. The total study duration extends to December 2026, covering cases treated since early 2017.

This research aims to evaluate the use and safety of Motiva Implants in people undergoing breast implant procedures. The study focuses on collecting and assessing safety and effectiveness data about these implants after they have been approved and are in general use. It includes participants who have primary breast augmentation, revision breast augmentation, or other aesthetic surgeries, with a focus on female patients aged 22 and older. Participants will receive Motiva Implants as part of their breast surgery or undergo other aesthetic procedures. The study is prospective and non-randomized, with data collected at baseline before surgery, during the operation, and annually for up to 10 years after surgery. Participants who have revision surgery or other aesthetic procedures without implants are also included as control groups to compare outcomes. During the study, participants will have various assessments including medical imaging such as CT, ultrasound, or MRI if medically advised. Researchers will monitor for connective tissue disease signs and symptoms, reproductive complications, cancer diagnoses, local complications, and patient satisfaction over 10 years. The impact of RFID on imaging will also be assessed. Participants will be followed for up to 10 years, providing long-term data on the safety and performance of Motiva Implants.

Researchers are evaluating the long-term safety and tolerability of ianalumab in adolescents and adults with moderate-to-severe systemic lupus erythematosus SLE who have previously completed treatment in one of two core SIRIUS-SLE studies. This Phase 3 extension study compares monthly or quarterly subcutaneous ianalumab to monthly placebo in participants who are positive for anti-nuclear antibodies ANA. The study aims to understand how ianalumab performs over an extended period in this patient group. Participants receive ianalumab either monthly or quarterly via subcutaneous injection, or a monthly placebo injection, throughout the extension study. Only those who completed the initial 60-week treatment period of the core studies without discontinuation are eligible. The study involves random assignment to one of the three groups and follows a quadruple-blind design to ensure unbiased results. During the trial, participants are monitored for treatment-emergent adverse events and serious adverse events up to approximately 91 months. Researchers also assess lupus disease activity, damage progression, corticosteroid use, and flare rates. Safety and tolerability are closely observed through regular evaluations, with the study lasting until April 2032, allowing for comprehensive long-term data collection.

Researchers are investigating whether combining the investigational drug mevrometostat PF-06821497 with enzalutamide works better than enzalutamide alone for men with metastatic castration-sensitive prostate cancer mCSPC who have not previously received androgen receptor pathway inhibitors ARPI or chemotherapy in this setting. This Phase 3, global, multicenter, randomized, double-blind, placebo-controlled study aims to compare these treatments to understand if the combination improves outcomes for participants. Participants will be randomly assigned to one of two groups one group will receive mevrometostat 875 mg twice daily plus enzalutamide 160 mg once daily, while the other group will receive a placebo plus enzalutamide 160 mg once daily. The study includes several phases Screening, Randomization, Treatment, Safety Follow-up, and Long-Term Follow-up. Prior short-term androgen-deprivation therapy ADT of up to 3 months is allowed if there is no disease progression before starting the study. During the study, participants will have regular assessments including radiographic scans to monitor disease progression, laboratory tests, patient-reported questionnaires on pain and quality of life, and blood samples to evaluate tumor DNA and drug levels. The main measure is radiographic progression-free survival tracked for up to about 4 years. Safety outcomes and overall survival will also be monitored for several years. The total participation may last up to nearly 9 years, including long-term follow-up to understand treatment effects and safety over time.

Researchers are studying a treatment called MANP modified atrial natriuretic peptide for people with difficult to control or resistant hypertension. This Phase 2 study compares the safety and effects of daily MANP injections to a placebo in reducing daytime systolic blood pressure over 42 days. Participants are adults aged 18 to 80 who are already taking three or more blood pressure medications. Participants will be randomly assigned to receive either MANP or a placebo injection once daily for 42 days. The MANP is given as a subcutaneous injection. The study is double-blind, meaning neither participants nor researchers know who receives the active treatment or placebo until the study ends. A subset of participants with slightly reduced kidney function may also be included, but not exceeding 10% of total enrollment. During the study, participants will have their blood pressure monitored closely using 24-hour ambulatory blood pressure devices and clinic measurements. Safety will be assessed through reports of side effects and serious adverse events up to 4 weeks after treatment ends. Blood samples will be taken for pharmacokinetic and antibody testing. The total study duration includes about 42 days of treatment plus 4 weeks of safety follow-up.
