NCT05085366
The main purpose of this study is to evaluate the efficacy of mRNA 1647 vaccine in CMV-seronegative female participants and to evaluate the safety and reactogenicity of mRNA-1647 vaccine in all participants. The purpose of the Phase 3 extension substudy is to extend the observation period of the main study and to assess the longer-term immunogenicity, efficacy, and safety of the mRNA-1647 vaccine against primary CMV infection in healthy females who were CMV-seronegative at Baseline of the mRNA-1647-P301 main study (including participants who remain CMV-seronegative upon entry into the extension substudy and participants who seroconverted during the main study). The extension substudy will also evaluate the immune persistence and safety of mRNA-1647 in a subset of female participants who were CMV-seropositive at Baseline of the main study. No interventional vaccine will be administered in the extension substudy.

This is a study to evaluate the pharmacokinetic (PK) and safety of sonelokimab in adolescent patients with HS.
NCT04949256
The purpose of this study is to assess the efficacy and safety of pembrolizumab plus lenvatinib plus chemotherapy compared with pembrolizumab plus chemotherapy as first-line intervention in participants with metastatic esophageal carcinoma. The primary hypotheses are that pembrolizumab plus lenvatinib plus chemotherapy is superior to pembrolizumab plus chemotherapy with respect to overall survival (OS) per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR). As of Amendment 09, Study MK-7902-014 will begin close out activities. Any participant who discontinues study intervention for any reason will be discontinued from the study without further follow-up. Second Course and treatment beyond disease progression will no longer be offered. No safety concerns contributed to the termination of this study.

NCT02987257
The North American Therapeutics in Epidermal Necrolysis Syndrome (NATIENS) study is a multicenter double-blind randomized controlled assessment of two arms - one of systemic immunomodulatory therapy (etanercept) and one of supportive care deemed to be the current standard of care. We will leverage the opportunity of this controlled design to collect multiples samples with an aim to discover new genetic and biological markers for prevention and early diagnosis and define cellular and molecular mechanisms to facilitate discovery of promising treatment strategies. This study has been preceded by a planning phase to ensure testing and development of harmonized supportive care infrastructure and operating procedures across sites.
NCT07281027
The goal of this clinical trial is to find out whether two existing medications-anakinra and tocilizumab-can effectively treat a rare and life-threatening brain condition called NORSE (New-Onset Refractory Status Epilepticus). NORSE causes continuous seizures in previously healthy children and adults and does not respond to standard treatments. It often leads to long-term disability or death. Doctors currently use anakinra and tocilizumab as second-line treatments when first-line therapies fail, but there is no clear evidence showing which drug works better or when it should be given. This study aims to answer those questions. The study will enroll patients across 33 hospitals in the United States, Canada, Europe, and Asia. It includes two groups: 1. Randomized Cohort Patients will be randomly assigned to receive either anakinra or tocilizumab within the first 7 days of their illness. Only patients whose doctors were already planning to use one of these medications as part of standard care will be eligible for randomization. Researchers will monitor their recovery and compare outcomes between the two treatments. 2. Observational Cohort Patients who cannot be randomized-usually because they were diagnosed too late-will still be followed to study how the timing of treatment affects recovery. Participants will: * Receive one of the two medications (depending on their group assignment). * Take part in follow-up assessments over the course of one year, including medical evaluations and surveys. Some participants may be followed annually beyond one year. * Optionally participate in a 60-minute interview to share their or their caregiver's experience with NORSE.
NCT05731271
The goal of this clinical trial is to test the safety of TST003 in patients with cancer. The main question\[s\] it aims to answer are: * What is the recommended dose patients can safely receive? * How long does this drug remain in the body after administration? * What are the side effects of this drug? * Does your cancer respond to TST003? * Participants on this study will get TST003 intravenously (through a needle into your vein), once every 3 weeks. * You may need to come to the study site 2-4 times to have tests to see if you are eligible to be in the study before you begin to receive the study drug. * After you start the study drug, you will need to return to the site several times after each dose so the physician can take vital signs, draw blood samples, and evaluate you for safety and wellbeing. * Participants will continue taking the drug as long as they are receiving clinical benefit. * At the end of your study participation, additional testing is required.
NCT06433635
This is a sequential multiple assignment randomized trial for adults (ages \> 18) with a bipolar disorder type 1 and type 2 diagnosis currently experiencing a depressive episode. It is a randomized pragmatic trial that will compare four commonly prescribed treatments for bipolar depression, which includes three FDA-approved medications (Cariprazine, Quetiapine and Lurasidone) and one antipsychotic/antidepressant combination (Aripiprazole/Escitalopram).
NCT06919016
This is a phase 1, first-in-human (FIH) trial for two vaccines, DV700P-RNA and DV701B1.1-RNA. This means it is the first time these study products are being tested in people. The purpose of this study is to see if the study products are safe, if people are able to take them without becoming too uncomfortable, and how a person's immune system responds to them (a person's immune system protects them from infections and disease). Forty-five volunteers without HIV and in overall good health, aged 18 to 55 years, will be enrolled and be in this study for about 16 months (about 12 visits), Study procedures will include blood draws, injections, and the collection of white blood cells and cells from their lymph nodes.
