NCT02858076
Although vitreous hemorrhage (VH) from proliferative diabetic retinopathy (PDR) can cause acute and dramatic vision loss for patients with diabetes, there is no current, evidence-based clinical guidance as to what treatment method is most likely to provide the best visual outcomes once intervention is desired. Intravitreous anti-vascular endothelial growth factor (anti-VEGF) therapy alone or vitrectomy combined with intraoperative PRP each provide the opportunity to stabilize or regress retinal neovascularization. However, clinical trials are lacking to elucidate the relative time frame of visual recovery or final visual outcome in prompt vitrectomy compared with initial anti-VEGF treatment. The Diabetic Retinopathy Clinical Research Network Protocol N demonstrated short-term trends consistent with a possible beneficial effect of anti-VEGF treatment in eyes with VH from PDR, including greater visual acuity improvement and reduced rates of recurrent VH as compared with saline injection. It is possible that a study with a longer duration of follow-up with structured anti-VEGF retreatment would demonstrate even greater effectiveness of anti-VEGF for VH to avoid vitrectomy and its attendant adverse events while also improving visual acuity. On the other hand, advances in surgical techniques leading to faster operative times, quicker patient recovery, and reduced complication rates may make prompt vitrectomy a more attractive alternative since it results in the immediate ability to clear hemorrhage and to perform PRP if desired, often as part of one procedure. This proposed study will evaluate the safety and efficacy of two treatment approaches for eyes with VH from PDR: prompt vitrectomy + PRP and intravitreous aflibercept injections.
NCT00704730
The purpose of this research study is to evaluate the progression-free survival (PFS) with XL184 as compared with placebo (an inactive substance) in subjects with unresectable, locally advanced, or metastatic medullary thyroid cancer (MTC). Subjects will be randomized to receive XL184 or placebo in a 2:1 ratio. XL184 is an investigational drug that inhibits VEGFR2, MET and RET, kinases implicated in tumor formation, growth and migration. The Clinical Steering Committee for this study, comprised of study doctors who specialize in medullary thyroid cancer, has provided guidance regarding the design of the study. The committee includes: Douglas Ball, MD, Barry Nelkin, PhD, Martin Schlumberger, MD and Steven Sherman, MD.
NCT01838551

NCT02787213
Prospective multicenter observational study to further develop and validate a preterm birth risk predictor, using a preterm cutoff at 37 0/7 weeks gestation and at 35 0/7 weeks gestation. A single maternal peripheral blood sample will be collected for analysis. Data related to potential risk factors for preterm birth will be obtained through maternal interview and review of medical records. Subjects will be followed through the delivery process to assess the course of pregnancy, labor, and to document any related maternal complications. Neonatal outcomes will be gathered from the medical record for up to 28 days of life or discharge, whichever occurs first.
NCT01857193
Dose Escalation part of the study: To estimate the MTD(s) and/ or RP2D of LEE011 in combination with everolimus + exemestane, and LEE011 in combination with exemestane, and to characterize the safety and tolerability of the combinations of everolimus + exemestane + LEE011 and LEE011 + exemestane in patients with ER+ HER2- advanced breast cancer Dose Expansion part of the study: To characterize the safety and tolerability of the triplet combination of LEE011 + everolimus + exemestane in patients naïve or refractory to CDK4/6 inhibitor based therapy, and the safety and tolerability of the doublet combination of LEE011 + exemestane in patients refractory to CDK4/6 inhibitor based therapy (except patients treated with prior LEE011 are not allowed in Group 3).
NCT01441882
This phase II trial studies how well dasatinib works in treating patients with chronic lymphocytic leukemia (CLL). Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
NCT02019888
The accurate assessment of auditory status is critical for planning treatment for Veterans with hearing loss to include medical and audiological management. Current physiologic tests of auditory function in the standard clinical audiological test battery for Veterans have limited sensitivity in detecting some middle-ear disorders, and do not include a direct test of cochlear function. Recent studies have shown promise for new wide-bandwidth (WB) tests of absorbance for improved sensitivity in the assessment of middle-ear function including acoustic reflex testing. The addition of WB tests of cochlear function included in the WB test battery provides an opportunity to improve audiological diagnosis of a range of hearing disorders in Veterans. The automation provided by the WB test battery could provide additional benefits in reducing the duration of the evaluation, leaving more time for evaluation of test findings and counseling. Results from this study may lead to the improvement of audiological care for Veterans with hearing loss.
NCT01201356
The purpose of this study was to collect long-term safety and tolerability, long-term efficacy, and health outcome data in all patients currently ongoing in the fingolimod multiple sclerosis clinical development program. This study combined all currently ongoing Phase II and III fingolimod extension studies as well as ongoing and newly planned studies into one single long-term extension protocol that provided patients with continuous treatment until fingolimod was registered, commercially available, and reimbursed in the respective countries.

NCT03380429
GlaxoSmithKline (GSK) in collaboration with Propeller Health has developed a sensor, which can clip on to the ELLIPTA® dry powder inhaler (DPI) and monitor the time and date that the ELLIPTA DPI cover is fully opened and closed. Additionally, a sensor will be attached to the rescue medication metered dose inhaler (MDI). The data from both sensors will be fed back to the subject via an application (app) on smart phone and will be reviewed by the subject's health care professional (HCP) via an online dashboard. The sensors, app, dashboard and systems to provide data comprise the CIS. This study will be the first to evaluate the effect of CIS on adherence to maintenance therapy in subjects with uncontrolled asthma. This is an open-label, randomized, parallel group study in asthmatic subjects currently on a fixed dose inhaled corticosteroid (ICS)/long-acting beta 2 agonist (LABA) maintenance therapy. Eligible subjects will receive RELVAR®/BREO® maintenance therapy via ELLIPTA DPI and salbutamol rescue medication via MDI with sensors attached to both inhalers during the run-in period, which may last for up to 3 months. Eligible subjects will then be randomized into five treatment arms depending on whether the data, from RELVAR/BREO ELLIPTA or RELVAR/BREO ELLIPTA and salbutamol MDI, is fed back to the subject or subject and HCP, or not at all. The treatment period for the study is approximately 6 months and there will be a follow-up period one week post last visit. The total duration of a subject in the study will be approximately 9 months. RELVAR, BREO and ELLIPTA are registered trademarks of GlaxoSmithKline group of companies.
