Nashville, TN Paid Clinical Trials

This is an open-label, multicenter, two-arm Phase II clinical trial that will evaluate the impact of 2nd line chemotherapy (i.e. capecitabine) on survival in patients with non-Luminal A hormone receptor-positive (HR+) metastatic breast cancer (MBC) Read Less

This clinical trial studies side effects and best treatment time of cryodevitalization in treating patients with early stage (stage I or stage II) lung cancer. Cryodevitalization is a type of cryosurgery that uses a flexible probe (cryoprobe) to kill tumor cells by freezing them. It is delivered at the time of standard diagnostic robotic bronchoscopy. Using cryodevitalization may be safe, tolerable and/or effective in treating patients with early stage lung cancer. Read Less

The study is a randomized, double-blind, placebo-controlled, multicenter study of standard treatment with nab-paclitaxel and gemcitabine with or without SBP-101 in subjects previously untreated for metastatic pancreatic ductal adenocarcinoma (PDA), including subjects who have received prior neoadjuvant or adjuvant treatment.

Lung allograft recipients have a higher burden of influenza disease and greater associated morbidity and mortality compared with healthy controls. Induction and early maintenance immunosuppression is thought to impair immunogenicity to standard dose inactivated influenza vaccine. This early post-transplant period is when immunity is most desirable, since influenza disease during this time frame is associated with adverse consequences. Thus, strategies to reduce severe influenza disease in this highly susceptible population are critical. No trials in lung transplant recipients have evaluated two doses of HD-IIV within the same influenza season as a strategy to improve immunogenicity and durability of influenza prevention. Furthermore, no influenza vaccine trials have focused on enrollment of subjects at early post-transplant timepoints. Very few studies have been performed in solely lung allograft recipients. Immunosuppression intensity is highest in lung patients, thereby limiting comparisons to recipients of heart, liver, and kidney transplants. Therefore, studies to assess both HD-IIV and two-dose strategies in the same influenza season in post-lung transplant recipients are greatly needed. The central hypothesis of our proposal is that lung allograft recipients who are 1-35 months post-transplant and receiving two doses of HD-quadrivalent inactivated influenza vaccine (QIV) will have higher HAI geometric mean titers (GMT) to influenza antigens compared to those receiving two doses of SD-QIV. To test this hypothesis and address the above critical knowledge gaps, we propose to conduct a phase II, multi-center, randomized, double-blind, controlled immunogenicity and safety trial comparing the administration of two doses of HD-QIV to two doses of SD-QIV in lung allograft recipients 1-35 months post-transplant. The results of this clinical trial will address significant knowledge gaps regarding influenza vaccine strategies (e.g., one vs. two doses and HD-QIV vs. SD-QIV) and immune responses in lung transplant recipients and will guide vaccine recommendations during the post-transplant period.

This is an Investigator initiated retrospective and prospective single cohort study. The study will utilize an international registry and develop a specimen biobank to provide an improved understanding of the natural history of hyposplasminogenemia, to elucidate the heterogeneity of phenotypic expression, identify markers to predict disease course, and inform improved therapeutic modalities Read Less

This is a research study in women to compare the outcomes of two procedures that restore blood flow to the arteries of the heart. In one procedure the blockages are ballooned and then stented with a small wire mesh tube through a small incision in the wrist or the groin. The other procedure is an open-heart operation in which healthy blood vessels from inside the chest, leg, and/or forearm are used to "bypass" the blockages (like a detour). Outcomes will be measured by comparing survival and improvement in quality-of-life. Read Less

Pseudohypoparathyroidism is a genetic disorder with limited treatment options, characterized by early-onset obesity, short stature and resistance to multiple hormones. This phase 2 clinical trial and open-label extension study will test the efficacy of theophylline, a phosphodiesterase inhibitor, in pseudohypoparathyroidism. We hypothesize that theophylline will cause weight loss, slow the rate of growth plate closure and decrease hormone resistance in children. Read Less

Supine hypertension is a common problem that affects at least 50% of patients with primary autonomic failure. Supine hypertension can be severe and complicates the treatment of orthostatic hypotension. The purpose of this study is to assess whether continuous positive airway pressure (CPAP) decreases blood pressure in autonomic failure patients with supine hypertension. Read Less

The automated inflatable abdominal binder is an investigational device for the treatment of orthostatic hypotension (low blood pressure on standing) in patients with autonomic failure. The purpose of this study is to determine safety and effectiveness of the automated abdominal binder in improving orthostatic tolerance in these patients. Read Less

Many persons with autonomic failure often have high blood pressure when lying down (supine hypertension). This study is exploring the impact of decreased venous return to the heart (achieved by raising the head of the bed) to lessen supine blood pressure. If decreased venous return to the heart is effective at lowering supine blood pressure, these approaches may be utilized to treat supine hypertension non-pharmacologically. Raising the head of the bed decreases the amount of blood returning to the heart due to the effects of gravity. In this case, the decreased blood return to the heart may decrease blood pressure.

Metabolic surgery is an emerging option to treat obesity-related metabolic diseases (e.g., type 2 diabetes) and prevent cardiovascular disease (CVD). Metabolic surgery can profoundly alter the gut microbiota; meanwhile, gut microbiota may affect surgical outcomes. Longitudinal studies that examined pre- to post-surgery changes in gut microbiota and its relation to cardiometabolic health after surgery are limited. Furthermore, few studies have included African Americans, a population with high rates of cardiometabolic diseases. The investigators aim to fill these research gaps by establishing a longitudinal, observational study of metabolic surgery patients and applying multi-omics to identify stool, blood, and/or tissue microbial features related to post-surgery cardiometabolic outcomes. In the current study, the investigators plan to enroll up to 300 patients who undergo metabolic surgery at Vanderbilt University Medical Center and follow them for up to 10 years after surgery. Fasting blood and stool samples will be collected at pre-surgery and 3-month, 1-year, 2-year, and 3-year post-surgery clinical visits. Tissue samples (e.g., biopsies of the liver and adipose and remnants of the stomach) will be collected during operation. Meanwhile, participants will complete a REDCap survey at baseline and 1-year, 2-year, and 3-year post-surgery. Participants' electronic medical records will be used to obtain additional information and facilitate long-term follow-up. The investigators will evaluate pre- to post-surgery changes in the fecal microbiome and fecal and blood levels of metabolites and proteins and the associations of microbiome, metabolites, and proteins with cardiometabolic improvements after surgery. This study will advance our understanding of the role of gut microbiota in metabolic surgery, which may translate into novel approaches to identify and treat obese patients for better cardiometabolic health.
