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.
NCT07011667
This study will look at how well CagriSema helps people living with obesity to lose weight and maintain the weight loss long-term. The study has 2 parts: The first part is called 'the main study' and the second part is called 'the extension study'. In the main study participants will either get CagriSema (a study medicine) or placebo (a dummy medicine that looks like CagriSema but has no active ingredient). Which treatment participants get is decided by chance. Participants are two times more likely to get CagriSema than placebo. If participants get CagriSema in the main study, participants will continue on CagriSema in the extension study. Which dose of CagriSema participants will continue on is decided by chance. If participants get placebo in the main study, participants will get CagriSema in the extension study. Participants will take one injection of study medicine once a week. The study will last for about 3 years and 3 months.
NCT04909203
This study is a 16-week intent-to-treat randomized controlled trial (RCT) with 120 suicidal juvenile justice (JJ)-involved transition-age (TA) youth (age 15-21 years) and a primary caregiver (dyads). Dyads will be randomly assigned to iKinnect2.0 (n=60 dyads) or Life360 (control app) plus an electronic suicide resources brochure (n=60 dyads). This design will test iKinnect2.0's new features for suicide prevention against TA youth awareness of and access to high-quality suicide prevention resources, while simultaneously testing features relating to conduct problems and parent management against parents knowing the TA youth's whereabouts in real-time and controlling for dyad member engagement in technology (Life360). Participants will be assessed at baseline, 4, 8 and 16 weeks. Primary youth-reported outcomes relating to suicide risk include: Suicidal behaviors (ideation, planning, attempts), non-suicidal self-injurious behaviors, self-efficacy in coping with distress, and use of imminent distress coping strategies (behavioral skills, use of crisis stabilization plan). Youth will also report on their criminal behavior. Primary caregiver-reported outcome variables relating to youth suicide include: Self-efficacy in applying family-based suicide-prevention strategies and reported use of those strategies; caregivers will also report on their own functioning (efficacy/confidence in parenting skills, life stress), TA youth functioning (internalizing and externalizing symptoms), parental management behaviors (expectation clarity, parental monitoring, discipline effectiveness/consistency, use of rewards), and parent-youth relationship quality (communication, conflict, support). App satisfaction and use of technology outcomes (i.e., degree of app usage, features used) will be examined and reported descriptively.

NCT05852938
Safety and Efficacy of BION-1301 in Adults with IgA Nephropathy
NCT04706507
This is a phase 3 study designed to evaluate whether the administration of ganciclovir increases ventilator-free days in immunocompetent patients with sepsis associated acute respiratory failure. Our hypothesis is that IV ganciclovir administered early in critical illness will effectively suppress CMV reactivation in CMV seropositive adults with sepsis-associated acute respiratory failure thereby leading to improved clinical outcomes
NCT06518057
This phase II clinical trial studies how well craniospinal irradiation (CSI) with hippocampal avoidance, using proton therapy or volumetric modulated arc therapy (VMAT), works in treating patients with breast cancer or non-small cell lung cancer (NSCLC) that has spread from the original (primary) tumor to the cerebrospinal fluid (CSF) and meninges (thin layers of tissue that cover and protect the brain and spinal cord) (leptomeningeal metastases). Radiation therapy is an effective treatment in relieving localized symptoms caused by leptomeningeal metastases. However, the type of radiation therapy typically used does not prevent the spread of leptomeningeal disease. CSI (radiation therapy directed at the brain and spinal cord to kill tumor cells) may be able to target all of the areas of possible leptomeningeal tumor spread. CSI may however result in significant neurological side effects due to radiation damage to a part of the brain called the hippocampus. Hippocampal avoidance (HA) reduces the amount of radiation to the hippocampus. Proton or VMAT CSI with HA may be an effective treatment while reducing neurological side effects for patients with leptomeningeal metastases from breast cancer and NSCLC.
NCT03615326
The study will compare the efficacy and safety of pembrolizumab plus trastuzumab in combination with standard of care (SOC) chemotherapy versus trastuzumab in combination with SOC chemotherapy in participants with HER2-positive gastric cancer. The primary hypotheses of the study are that pembrolizumab plus trastuzumab in combination with chemotherapy is superior to trastuzumab plus chemotherapy in terms of 1) progression free survival (PFS) per Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1) as assessed by blinded independent central review (BICR), and 2) overall survival (OS).
NCT06188689
Calcium Release Deficiency Syndrome (CRDS) is a novel inherited arrhythmia syndrome secondary to RyR2 loss-of-function that confers a risk of sudden cardiac death. Diagnosis of CRDS presently requires cellular-based in vitro confirmation that an RyR2 variant causes loss-of-function. We hypothesize that CRDS can be diagnosed clinically through evaluation of the repolarization response to brief tachycardia, mediated by cardiac pacing, and a subsequent pause.
NCT06144840
To investigate the efficacy of MT-7117 on time to onset and severity of first prodromal symptoms (burning, tingling, itching, or stinging) associated with sunlight exposure in adults and adolescents with EPP or XLP.
NCT05478252
The study compares two semaglutide medicines and looks at how well they control blood sugar levels, in participants with type 2 diabetes (T2D). Participants will either get the currently available semaglutide or the semaglutide which is produced through a new manufacturing process. Participants need to take one injection of semaglutide once a week, on the same day of every week. Participants will have a total of 11 clinic visits and the study will last for about 35 weeks (approximately 8 months).

NCT06754462
This Phase 2b, multicenter, double-blind, placebo-controlled, randomized withdrawal study is designed to assess the efficacy and safety of IMVT-1402 in adult participants with active, difficult-to-treat, anti-citrullinated protein autoantibody (ACPA) positive rheumatoid arthritis (RA).
NCT05981092
The purpose of this study is to learn about the natural progression of DCM (dilated cardiomyopathy) caused by BAG3 gene mutations. DCM is a condition as the heart muscle is weakened and the heart becomes enlarged. This makes it hard for the heart to pump enough blood for the body. The study is seeking up to about 35 participants who have: * BAG3 mutation (change in the gene) that causes or is likely to cause dilated cardiomyopathy * NYHA (New York Heart Association) Class I-IV at screening (Stage B-D) * Left Ventricular Ejection Fraction less than or equal to 50% (meaning reduced heart function) All participants in this study will receive their usual treatment. The investigators will observe the natural progression of people who have BAG3 DCM. This will help the investigators better understand the disease and aid in future research. Participants will take part in this study for three years. During this time, participants will visit the site at least 8 times (about every 3 months for the first year and annually during year 2 and three). Participants will undergo study procedures and give information about their health. These procedures will include a physical exam, cardiac magnetic resonance imaging, echocardiography, ECG monitoring, activity monitoring, cardiopulmonary exercise testing, and blood tests. Participants will answer questions about health and quality of life. The study team will also call participants about 1 time over the phone.
