There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Absolute voice rest is commonly prescribed after vocal fold surgery, also known as phonomicrosurgery, for benign vocal fold lesions. This is thought to decrease scarring of vocal folds, which could result in increasing tissue stiffness and limitations in optimal vocal outcome. Unfortunately there is no standardized protocol as to how long patients should rest their voice after phonomicrosurgery. To date, there are no studies in the literature directly comparing the impact of short-term and long-term voice rest on vocal fold healing and voice outcome after phonomicrosurgery.
This phase II trial studies how well midostaurin and decitabine work in treating older patients with newly diagnosed acute myeloid leukemia and FLT3 mutations. Midostaurin and decitabine may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
The investigators propose a randomized non-blinded comparison of dorsal vs. ventral approach for buccal mucosa graft urethroplasty in the bulbar urethra. Buccal mucosa graft is a common method of repairing the strictured urethra. Current evidence suggests the two approaches for placement of the graft are equally successful at correcting the stricture and the two approaches have similar risks of complications. The investigators propose to randomly assign appropriately selected patients to either a dorsally- or ventrally-placed graft. No additional procedures beyond normal care protocol will be required of the patients. Success will be assessed via objective and subjective methods; complications will be tallied in a standardized fashion. Outcomes will be measured at two years.
Elevated blood cholesterol, and particularly LDL cholesterol, is a risk factor for heart disease. Tocotrienols are naturally-occurring compounds in foods that may have beneficial effects on blood cholesterol. Tocotrienols are members of the vitamin E family, and are found in barley, oats, rye, coconut oil and rice bran oil, but the richest source of tocotrienols is palm oil. Certain of these tocotrienols have been shown to be effective in lowering LDL (or 'bad') cholesterol, with no adverse effects on the HDL (or 'good') cholesterol. The purpose of this study is to determine the effects of a palm-oil derived tocotrienol supplement on blood cholesterol, and particularly LDL cholesterol, in individuals who are taking statins, and have either elevated or normal cholesterol levels. Study subjects will consume a palm-oil derived supplement of tocotrienol for 3 months to determine its effects on LDL cholesterol.
The aim of this study is to define a new treatment technique for T1a larynx cancer that maintains excellent local control with less extensive radiation fields. It is thought that this will lead to patients having fewer changes to their voice and a higher quality of life after treatment when compared to the current standard treatment.
This is a multicenter, open-label trial to evaluate the safety and efficacy of inhaled treprostinil in subjects with pre-capillary pulmonary hypertension (PH) associated with interstitial lung disease (ILD) including combined pulmonary fibrosis and emphysema (CPFE). The study will include about 266 patients who completed all required assessments in the RIN-PH-201 study at approximately 100 clinical trial centers. The study will continue Your participation in this study is voluntary and will last until you discontinue from the study or the study ends. The study will continue until each subject reaches the Week 108 visit or until inhaled treprostinil become commercially available for patients with PH associated with ILD including CPFE (whichever is sooner).
This is an open label phase I clinical trial of hydroxychloroquine (HCQ) ,when it is combined with the usual medications for acute myeloid leukemia, mitoxantrone and etoposide. The purpose of this study is to find the safest and most effective dose of hydroxychloroquine with these medications. The investigators will be testing to see if it can increase the effectiveness of mitoxantrone and etoposide.
In a 6 week pilot study, 20 individuals with habitual sleep restriction will all be asked to extend their nightly sleep by 1 hour, and will then be randomized 1:1 to nightly controlled-release oral melatonin (2mg) or placebo. The investigators will assess whether sleep extension and nightly melatonin supplementation in the community is a feasible intervention with a beneficial effect on the following chronic kidney disease (CKD) risk factors: systemic and renal specific renin-aldosterone-angiotensin system (RAAS) activation (systemic plasma renin activity, plasma angiotensin II levels, 24-hour urine aldosterone excretion, and renal plasma flow response to captopril); nocturnal blood pressure measured by 24-hour ambulatory blood pressure monitor; central blood pressure measured by pulse wave analysis; and glucose metabolism measured by Minimal Model assessment of insulin resistance and β-cell response to a mixed meal protocol.
The goal of this study is to determine whether timolol eye drops are effective in alleviating acute migraine headaches. Subjects will be randomized to receive either timolol eye drops or placebo (tears) to use as a migraine abortive medication.
The study is planned to be conducted in 2 parts. The first part (open label, multi-center, non-controlled) of the study will estimate a dose that would provide a mycophenolic acid (MPA) exposure in pediatric participant that is comparable to that achieved in adult liver transplant participants receiving the approved dose of mycophenolate mofetil (MMF, CellCept). The second part (open-label, multi-center, single-arm Phase IV study) of the study will provide the pharmacokinetics, efficacy and safety profile of the proposed dose in the immediate post-transplant period. This study will be conducted at two centers based in the United States of America. Twelve pediatric transplant participants receiving a first liver allograft from a cadaveric or living donor will be enrolled in this study. Stable pediatric liver transplant participants who are at least 6 months post-transplant and who were already receiving stable dose of MMF in combination with cyclosporine will be enrolled into the study. Participants should have received stable MMF dose according to center practice for at least seven days in order to get steady state pharmacokinetics (PK). Participants also should have received stable concomitant doses of cyclosporine (for at least 2 days) and corticosteroids per center practice. Participants will be aged between 9 months and 12 years, with at least 6 participants greater than or equal to (>/=) 9 months and less than (<) 36 months, of whom at least 2 will be <24 months.
