NCT00076102
Background: Neurofibromatosis Type 1 (NF1) is an autosomal dominant, progressive genetic disorder characterized by diverse clinical manifestations. Patients with NF1 have an increased risk of developing tumors of the central and peripheral nervous system including plexiform neurofibromas, which are benign nerve sheath tumors that may cause severe morbidity and possible mortality. The histopathology of these tumors suggests that events connected with formation of fibroblasts might constitute a point of molecular vulnerability. Gene profile analysis demonstrates overexpression of fibroblast growth factor, epidermal growth factor, and platelet-derived growth factor in plexiform neurofibromas in patients with NF1. Pirfenidone is a novel antifibrotic agent that inhibits these and other growth factors. Clinical experience in adults has demonstrated that pirfenidone is effective in a variety of fibrosing conditions and pirfenidone is presently under study in a phase II trial for adults with progressive plexiform neurofibromas. A phase I trial of pirfenidone in children and young adults with NF1 and plexiform neurofibromas was completed, and has established the phase II dose (the dose resulting in a mean drug exposure \[AUC\] not more than 1 standard deviation below the mean drug exposure \[AUC\] in adults who received pirfenidone at the dose level demonstrating activity in fibrosing conditions). Pirfenidone has been well tolerated. Objectives: To determine whether pirfenidone increases the time to disease progression based on volumetric measurements in children and young adults with NF1 and growing plexiform neurofibromas. To define the objective response rate to pirfenidone in NF1-related plexiform neurofibromas. To describe and define the toxicities of pirfenidone. Eligibility: Individuals (greater than or equal to 3 years to less than or equal to 21 years of age) with a clinical diagnosis of NF1 and inoperable, measurable, and progressive plexiform neurofibromas that have the potential to cause substantial morbidity. Design: The phase II dose will be used in a single stage, single arm phase II trial The natural history of the growth of plexiform neurofibromas is unknown. For this reason, time to disease progression on the placebo arm of an ongoing National Cancer Institute (NCI) Pediatric Oncology Branch (POB) placebo-controlled, double-blind, cross-over phase II trial of the farnesyltransferase inhibitor R115777 for children and young adults with NF1 and progressive plexiform neurofibromas.

NCT01537393
The purpose of this study is to determine if the 3-year graft failure rate following endothelial keratoplasty performed with donor corneas with a preservation time of 8 to 14 days is non-inferior to the failure rate when donor corneas with a preservation time of 7 or fewer days are used.
NCT02526524
The purpose of the study is to compare the glycemic effects of delayed-release metformin (Met DR) to placebo in subjects with type 2 diabetes mellitus (T2DM) over 16 weeks. The study is designed to evaluate several doses of Met DR (600 to 1500 mg once daily in the morning \[qAM\]) compared to placebo. A single-blind reference treatment of 2000 mg metformin immediate-release (Met IR) per day administered as equal divided doses (1000 mg Met IR BID) will also be included.
NCT01992250
This study examines the use of cryoablation as an alternative to surgery in the treatment of early stage invasive breast cancer. The hypothesis is that cryoablation will complete ablation and destroy the tumor in a selected population of women who may otherwise be adequately treated with surgery.
NCT02136108
The OPEN study has two aims: The first is to identify what helps to keep patients involved with a Medicaid chronic pain management program and to identify features of an ideal text-message-based program for people enrolled in the program. The second aim is to develop the text-message-based program (OPENtext), then find out how useful this intervention is compared to a patient navigator intervention (OPENnav) for increasing patient engagement, improving patient's motivation to manage their chronic pain, and improving patient confidence in self-managing their chronic pain condition.
NCT01727297
This study is to determine, through continuous monitoring with the Reveal implantable cardiac monitor (ICM), the incidence of atrial fibrillation (AF) in patients suspected to be at high risk for having AF and to understand how physicians manage these patients after AF has been detected. This study will also seek to identify what patient characteristics are most predictive of developing AF.
NCT01469377
An outpatient study to evaluate the safety and efficacy of cariprazine as adjunct to antidepressant therapy (ADT) in participants with major depressive disorder (MDD) who have an inadequate response to ADT alone. This clinical study compared cariprazine + ADT with placebo + ADT in outpatients with a diagnosis of MDD and an inadequate response to ADT. The study consisted of approximately 2 weeks of screening and washout followed by 8 weeks of double-blind treatment followed by a 1 week safety follow-up.
NCT00094523
This study was designed to evaluate and compare safety, tolerability of subjects who successfully suppress HIV-1 on their first PI regimen to those who switch to fosamprenavir. This is a 48-week study, where subjects who were assigned to be in their original PI-group have the option of switching to fosamprenavir on week 24. Prior to being assigned their treatment group, subjects had to be suppressed for at least three months. All subjects also take a background regimen of two nucleoside/nucleotide reverse transcriptase inhibitors.
NCT01676701
The purpose of this study is to evaluate the serum concentration of tabalumab after the administration using either prefilled syringe or auto-injector after the initial loading dose and after 12 weeks of treatment. Treatment period is followed by 40 weeks optional safety extension.
NCT00512109
The investigators' study has 4 primary objectives. Among patients undergoing noncardiac surgery the investigators will determine: (1) the incidence of major perioperative vascular events; (2) the optimal clinical model to predict major perioperative vascular events; (3) the proportion of patients with perioperative myocardial infarctions that may go undetected without perioperative troponin monitoring; and (4) the relationship between postoperative troponin measurements and the 1 year risk of vascular death.
NCT01481740
Previous research regarding the use of phenylephrine has excluded obese subjects (BMI \>35). This subgroup of patients represents a large portion of the obstetric patient population locally and nationally. It is unclear whether previous research should be extrapolated to the obese patient population. This study is being done to compare the incidence of hypotension, intraoperative nausea and vomiting, and neonatal acidosis between obese patients who receive a prophylactic phenylephrine infusion versus those who receive phenylephrine boluses for the treatment of established hypotension. This study will help us determine whether using a phenylephrine infusion or a phenylephrine bolus is the best way to prevent/treat spinal induced hypotension during cesarean deliveries in obese patients.
