This is a 2-part (phase 2b/3) prospective, interventional, multicenter, randomized, double-blind, placebo-controlled study. Part 1 (phase 2b) is a dose-finding study for CSL300 vs placebo. Part 2 (phase 3) aims to assess the efficacy of CSL300 on cardiovascular (CV) outcomes and safety in subjects with systemic inflammation and either atherosclerotic cardiovascular disease (ASCVD) or diabetes with end stage kidney disease (ESKD) undergoing maintenance dialysis.

At the University of Iowa, the investigators led a multicenter randomized clinical trial comparing standard prophylactic dose to intermediate dose enoxaparin in hospitalized patients with COVID-19 (NCT04360824). As part of an exploratory biomarker component of this trial, blood samples were collected from hospitalized COVID-19 patients at enrollment and weekly for up to 30 days of hospitalization. The pilot results, as well as reports from other groups, demonstrate increased potential for thrombin generation in the plasma of COVID-19 patients. In particular, in the COVID-19 patient cohort enhanced thrombin generation potential persisted for at least 30 days of hospitalization. The investigators now propose to explore the mechanistic roles of activation of blood cells (such as platelets and neutrophils) and products of cellular activation as mediators of enhanced thrombin generation in patients with COVID-19. The study design will be a longitudinal cohort study, which will allow for the determination of the time course of enhanced thrombin generation potential in relation to clinical outcomes and changes in markers of cellular activation in serial samples obtained from COVID-19 patients for up to 3 years after infection with SARS-CoV-2. This study may provide clues to why a subset of COVID-19 patients present with late thrombotic complications even after apparent recovery from SARS-CoV-2 infection. An ongoing question in the field relates to the comparative prothrombotic effects of acute COVID-19 versus incidental SARS-CoV-2 infection versus acute infection with influenza viruses. Therefore, we will include three categories of hospitalized patients in this study: (1) acute COVID-19, (2) incidental COVID-19, and (3) acute influenza A or B. This project has a strong scientific rationale with direct clinical implications, especially given the emergence of SARS-CoV-2 variants such as delta and omicron that may prolong the pandemic and/or cause surges of COVID-19 in the coming months.

This clinical trial is designed to test whether a single image-guided intracerebral administration of inhibitory nerve cells, called interneurons (NRTX-1001), into subjects with drug-resistant unilateral mesial temporal lobe epilepsy (MTLE), with or without mesial temporal sclerosis (MTS), is safe (frequency of adverse events) and effective (seizure frequency). NRTX-1001 comprises human interneurons that secrete a neurotransmitter, gamma-aminobutyric acid (GABA). Read Less

This phase II trial studies the effect of capecitabine and temozolomide after surgery in treating patients with high-risk well-differentiated pancreatic neuroendocrine tumors. Chemotherapy drugs, such as capecitabine and temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving capecitabine and temozolomide after surgery could prevent or delay the return of cancer in patients with high-risk well-differentiated pancreatic neuroendocrine tumors. Read Less

This study will evaluate the efficacy, safety, and pharmacokinetics of the PDS with Ranibizumab in participants with DME when treated every 24 weeks (Q24W) compared with intravitreal ranibizumab 0.5 mg every 4 weeks (Q4W). The substudy will evaluate safety of re-implanting the updated PDS with ranibizumab and the refill-exchange procedures following re-implantation in participants with DME who were previously enrolled in the main Study, GR40550. Up to 100 participants from the main study will be enrolled and followed for a maximum of 72 weeks post-re-implantation in the substudy. Read Less

This randomized research trial studies how well serum tumor marker directed disease monitoring works in monitoring patients with hormone receptor positive Her2 negative breast cancer that has spread to other places in the body. Using markers to prompt when scans should be ordered may be as good as the usual approach to monitoring disease. Read Less

This study is a Phase 3, randomized, modified double-blind study which aims to measure whether the investigational pneumococcal conjugate vaccine PCV21 is safe and can help the body to develop germ-fighting agents called "antibodies" (immunogenicity) when it is given after 1 dose, 2 doses, or 3 doses of a licensed 20-valent pneumococcal vaccine compared to when 20-valent pneumococcal vaccine is given as a complete series in infants aged from approximately 2 months (42 to 89 days). The study duration per participant will be up to approximately 19 months. The study vaccines (either PCV21 or 20vPCV) will be administered at approximately 2, 4, 6 and 12 to 15 months of age (MoA). Routine pediatric vaccines will be given as per local recommendations. There will be 6 study visits: Visit (V)01, V02 separated from V01 by 60 days, V03 separated from V02 by 60 days, V04 separated from V03 by 30 days, V05 at 12 months of age until 15 months of age, V06 separated from V05 by 30 days.

The purpose of this study is to assess the safety and efficacy of divarasib compared to locally approved KRAS G12C inhibitors (sotorasib or adagrasib) in participants with KRAS G12C-positive (KRAS G12C +) advanced or metastatic non-small cell lung cancer (NSCLC). Read Less

This is a multi-site clinical study enrolling 2000 newly diagnosed patients with breast, colorectal, melanoma, non-Hodgkin lymphoma, or non-small cell lung cancer, who are planning to receive one or more systemic cancer directed therapies with chemotherapy and/or (immune checkpoint inhibitors) ICIs.

Study CL3-95031-007 (CHONQUER) is a Phase 3, international, multicenter, double-blind, randomized, placebo-controlled study of orally administered ivosidenib. Participants are required to have a histopathological diagnosis consistent with isocitrate dehydrogenase-1 (IDH1) gene-mutated, locally advanced or metastatic conventional chondrosarcoma Grades 1, 2, or 3 and not eligible for curative resection. IDH1 mutant status will be determined during pre-screening/screening phase. Participant must have radiographic progression/recurrence of disease according to Response Evaluation Criteria in Solid Tumors (RECIST v1.1) and have received 0 to 1 prior systemic treatment regimen in the advanced/metastatic setting for conventional chondrosarcoma. The primary endpoint is progression-free survival (PFS) in Grades 1 and 2 participants. Key secondary endpoints are PFS in all randomized participants, overall survival (OS) in Grades 1 and 2 participants, and OS in all randomized participants. Participants who meet enrollment criteria will be randomized 1:1 to receive oral ivosidenib 500mg once daily, or a matching placebo once daily. Read Less

This is parallel, Phase 4 study which consists of a 24 week (0.5 years) randomized, double blind, placebo controlled, 2-arm treatment period followed by an open label segment of 104 weeks (2 years) for a total of 128 weeks (2.5 years) to evaluate the effect of dupilumab treatment on esophageal function, and remodeling in adults with eosinophilic esophagitis. Duration of study period (per participant) * Screening period: Up to 12 weeks before Week 0 * Randomized double-blind period: 24 weeks * Open label period: 104 weeks * Post Investigational Medicinal Product (IMP) intervention follow-up period: up to 12 weeks or until the participants switch to commercialized dupilumab, whatever comes first. There will be ten (10) site visits, and five (5) direct-to-participant IMP delivery visits (except if prohibited by local regulatory authorities or if participant is not willing. In this case, IMP will be dispensed at the study site). Read Less
