NCT07192458
This will be a follow-up study to the "Comparison of High Dose vs. Standard Dose Influenza Vaccine in Lung Allograft Recipient" study (DMID Protocol Number 22-0014) at Vanderbilt University Medical Center. Lung transplantation is a life-saving therapy for patients with advanced lung disease, and is also associated with an improvement in quality of life. However, due to the need for life-long immunosuppression to prevent acute cellular rejection and chronic lung allograft dysfunction ("chronic rejection"), lung transplant recipients are at risk for developing major infections. In fact, one-year survival is 85%, with infection being the leading cause of death within the first year post-transplant. We will conduct a follow-up phase II, randomized, double-blind trial to assess the impact of subsequent administration of two doses of HD-IIV compared to two doses of SD-IIV among lung recipients during the early post-transplant period. Demonstration of improved immunogenicity from two doses of HD-IIV over consecutive influenza seasons would provide potential broad benefit in reducing influenza disease and its associated complications in lung transplant recipients. Moreover, studying vaccine immunogenicity and safety in the same participants over consecutive years can provide insight into the influence of immunosuppression levels and allograft aging on vaccine-mediated immune modulation. This proposed study design will contribute significantly to influenza vaccination guidance and policy for the highly vulnerable lung transplant population. This proposed study is designed to address several key knowledge gaps in vaccine-mediated protection of lung transplant recipients against influenza: * Is there increased immunogenicity with administration of one or two doses of HD-IIV or SD-IIV in the subsequent season compared to two doses of HD-IIV or SD-IIV in the first season? * What is the durability of the humoral and cellular immune response between influenza seasons and does two doses of HD-IIV or SD-IIV sustain higher HAI titers compared to two doses of HD-IIV or SD-IIV in the first season? * What is the impact of maintenance immunosuppression levels on influenza vaccine immunogenicity within the same participant? * Will the optimal immunogenic vaccination strategy be associated with an acceptable long-term safety profile over successive influenza seasons, including injection-site and systemic reactions, allosensitization, and organ rejection?

NCT05284747
The primary objective of this study is to evaluate the effectiveness of early treatment with evolocumab plus routine lipid management vs routine lipid management alone when administered in the acute setting to reduce myocardial infarction, ischemic stroke, arterial revascularization, and all-cause death in subjects hospitalized for an acute myocardial infarction (non-ST-segment elevation myocardial infarction \[NSTEMI\] and ST-segment elevation myocardial infarction \[STEMI\]).
NCT00637689
The purpose of this study is to see if recent guidelines proposed by the National Institutes of Health for the diagnosis, staging, and response assessment of people with chronic GVHD can improve our understanding of this complication. We will accomplish our goals by studying a large number of people with chronic GVHD over several years using information collected from health care providers, patients, laboratory studies and diagnostic tests. Several transplant centers in the United States are collaborating on this project.
NCT04095065
The overall objective of the proposed research is to reduce the incidence of sexually transmitted infections (STIs) among college students. The investigators propose to accomplish this by using the innovative, engineering-inspired multiphase optimization strategy (MOST) to develop a highly effective, appealing, economical, and readily scalable internet-delivered behavioral intervention targeting the intersection of alcohol use and sexual risk behavior. The rate of STIs on college campuses is alarming: one in four college students is diagnosed with an STI at least once during their college experience. Sexual activity when drinking alcohol is highly prevalent among college students. Alcohol use is known to contribute to the sexual risk behaviors that are most responsible for the transmission of STIs, namely unprotected sex, contact with numerous partners, and "hook-ups" (casual sexual encounters). Few interventions have been developed that explicitly target the intersection of alcohol use and sexual risk behaviors, and none have been optimized. In order to reduce the incidence of STI transmission among this and other high-risk groups, a new approach is needed. MOST is a comprehensive methodological framework that brings the power of engineering principles to bear on optimization of behavioral interventions. MOST enables researchers to experimentally test the individual components in an intervention to determine their effectiveness, indicating which components need to be revised and re-tested. Given the high rates of alcohol use and sex among college students, the college setting provides an ideal opportunity for intervening on alcohol use and sexual risk behaviors. The proposed study will include a diverse population of college students on 4 campuses which will increase the generalizability of the findings. The specific aims are to (1) develop and pilot test an initial set of online intervention components targeting the link between alcohol use and sexual risk behaviors, (2) use the MOST approach to build an optimized preventive intervention, and (3) evaluate the effectiveness of the newly optimized preventive intervention using a fully powered randomized controlled trial (RCT). This work will result in a new, more potent behavioral intervention that will reduce the incidence of STIs among college students in the US, and will lay the groundwork for a new generation of highly effective STI prevention interventions aimed at other subpopulations at risk.
NCT03438747
The aim of this trial is to evaluate if P-15L bone graft (investigational device) is not inferior in effectiveness and safety to local autologous bone (and allograft where necessary) as an extender (control device) when applied in instrumented transforaminal lumbar interbody fusion (TLIF) in subjects with degenerative disc disease (DDD). In addition to the general overall objective, a sub-group analysis will be performed on the high-risk subject population (tobacco use, obesity, diabetes), as previous studies have shown negative effects of smoking, obesity and diabetes on fusion and bone healing, increased peri/postoperative complications, and lower patient-reported outcome scores.

NCT03776812
This is a Phase 2, open-label, randomized, 3-arm study to evaluate progression-free survival (PFS) in patients with recurrent platinum-resistant ovarian, fallopian tube, or primary peritoneal cancer treated with intermittent or continuous regimens of relacorilant in combination with nab-paclitaxel compared with patients treated with nab-paclitaxel alone.
NCT01193088
This project includes two projects. One is looking for new genes that cause Charcot Marie Tooth disease (CMT). The other is looking for genes that do not cause CMT, but may modify the symptoms a person has.
NCT01193075
This is an observational longitudinal study to determine the natural history and genotype-phenotype correlations of disease causing mutations in Charcot Marie Tooth disease (CMT) type 1B (CMT1B), 2A (CMT2A), 4A (CMT4A), and 4C (CMT4C). The investigators will also be determine the capability of the newly developed CMT Pediatric Scale (CMT Peds scale) and the Minimal Dataset to measure impairment and perform longitudinal measurements in patients with multiple forms of CMT over a five year window
NCT06730100
This phase II trial studies how well CBX-12 works in treating patients with microsatellite stable colorectal cancer that has spread to other parts of the body (metastatic) and is no longer responding to chemotherapy treatment (chemotherapy-refractory). The usual approach to treating colorectal cancer includes treatment with surgery, radiation, or Food and Drug Administration (FDA)-approved drugs such as trifluridine-tipiracil, bevacizumab, regorafenib, or fruquintinib. However, most metastatic colorectal patients progress through all approved treatments and eventually succumb to their disease. CBX-12 is a drug that contains a peptide (a substance that contains many amino acids \[molecules that join together to form proteins\]) called pHLIP, linked to an anticancer substance called exatecan. Upon administration, pHLIP gets inserted into the cellular membrane of tumor cells, delivering exatecan to kill them. Giving CBX-12 may work better than the usual approach in treating patients with metastatic chemotherapy-refractory microsatellite stable colorectal cancer.

NCT06728553
The goal of this clinical trial is to learn if drug MTX101 works to treat acute migraine attacks in adults. It will also learn about the safety of the drug MTX101. The main questions it aims to answer are: Does the drug MTX101 lower headache pain for participants and the need to use a rescue medication? What side effects, if any, do participants have when taking the drug MTX101? Researchers will compare the drug MTX101 to a placebo (a look-alike substance that contains no drug) to see if the drug MTX101 works to treat acute migraine attacks. Participants will: Take the drug MTX101 or a placebo to treat 1 migraine attack with each treatment. Visit the clinic twice and have one phone call over a 4 week period for checkups and tests. Keep a diary of their symptoms and the number of times they use a rescue medication.
NCT02400190
This study will collect rates of local/regional recurrence in select patients who do not receive radiation treatment after lumpectomy surgery. These women must be postmenopausal; have hormone receptor-positive, Her2-negative tumors; have Oncotype-DX RS less than or equal to 18; and plan to receive endocrine therapy. In this way, this study seeks to collect prospective data supporting the idea that this is a population at sufficiently low risk of local/regional recurrence that omission of adjuvant radiation might be a reasonable option.
