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.
NCT02928445
This 6-month extension study will provide further information regarding the long-term safety and tolerability of intepirdine (RVT-101) in subjects with Dementia with Lewy bodies (DLB) who have participated in the double-blind, placebo-controlled, lead-in study RVT-101-2001.
NCT01586234
The primary goal of this study is to determine if excimer laser smoothing of the cornea before Descemet's stripping automated endothelial keratoplasty (DSAEK)improves postoperative Best Spectacle Corrected Visual Acuity (BSCVA).
NCT01510392
The primary goal of the trial is to show that optical coherence tomography (OCT) technology can be used to effectively screen for diseases of the eye including glaucoma, macular diseases and keratoconus. Glaucoma is a disease that causes permanent vision loss and is usually accompanied by increased eye pressure. Macular diseases affect sharp, central vision. Keratoconus is a disease that affects the cornea (clear surface covering the colored part of the eye).
NCT01342224
This study will add an immunotherapy component to chemotherapy and radiation treatment in patients who have pancreatic cancer. The objective of this study is to see if the combined treatment is safe and feasible, and if a larger study is warranted.
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.

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.

NCT02121418
This clinical trial studies decitabine and cytarabine in treating older patients with newly diagnosed acute myeloid leukemia, myelodysplastic syndrome that is likely to come back or spread to other places in the body, or myeloproliferative neoplasm. Drugs used in chemotherapy, such as decitabine and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Giving decitabine and cytarabine may work better than standard therapies in treating cancers of the bone marrow and blood cells, such as acute myeloid leukemia, myelodysplastic syndrome, or myeloproliferative neoplasm.
NCT01049412
Comparison of blood glucose levels in patients with Type 1 diabetes when they take a new basal insulin analog and when they take insulin glargine
NCT01283139
To evaluate the efficacy and safety of sifalimumab compared to placebo in subjects with moderately to severely active Systemic Lupus Erythematosus (SLE).
NCT01393405
There are fewer therapeutic options for patients with active ulcerative colitis (UC) compared to patients with active Crohn's disease (CD) and the investigators are facing a persistent unmet need for additional effective and affordable therapies for patients with UC. Methotrexate (MTX) 25 mg once weekly administered subcutaneously (sq) or intramuscularly (im) is an efficient therapy to induce and maintain steroid free remission in patients with CD. To evaluate the efficacy of a similar approach in patients with active ulcerative colitis the investigators conduct a double-blind, placebo controlled, randomized, multicenter, parallel group trial to investigate the safety and efficacy of 25 mg MTX applied subcutaneously once weekly in patients with active UC, who either failed 5-ASA therapy, or are steroid dependent or are intolerant or not responding to azathioprine/6-mercaptopurine therapy or have no response/ lost response to infliximab prior to the study inclusion. The study is designed as a drug withdrawal trial and includes two periods, the Induction Period (week 0-16) and the Maintenance Period (week 17-48). In the open label Induction Period every patient will receive a steroid taper, MTX 25 mg sq once weekly + daily folic acid 1 mg tablets for the induction of clinical response or remission. Patients responding to the open label MTX therapy and being off steroids between week 12-16 will be randomized at week 16 1:1 to Placebo sq once weekly + daily folic acid 1 mg tablets + 2.4 g mesalamine or to MTX 25 mg sq once weekly + daily folic acid 1 mg tablets+ 2.4 g mesalamine. The Specific Aims of the trial are: i) To evaluate the safety and tolerability of 25 mg MTX applied sq once weekly over a time period of 48 weeks; ii) To evaluate the relapse-free survival of MTX maintenance therapy compared to placebo over a time period of 32 weeks; iii) To evaluate the efficacy of MTX over a time period of 16 weeks to induce steroid free remission; iiii) To establish a DNA, plasma and serum library to enable the evaluation of clinical and pharmacogenomic models to predict the response to MTX therapy in patients with UC. With 25-30 participating centers actively enrolling, the investigators anticipate to complete enrollment for this study in a time period of 3 years. Completion of this trial will define the therapeutic value of MTX in UC, potentially changing the current therapeutic strategy in UC.
