NCT02136914
This is a multi-center, randomized, double-blind, placebo-controlled, 2-arm, parallel group study to evaluate the efficacy and safety of ADS-5102 extended release (ER) capsules, an investigational formulation of amantadine, dosed once nightly at bedtime for the treatment of levodopa induced dyskinesia (LID) in subjects with Parkinson's disease (PD). The novel pharmacokinetic profile of ADS-5102 is expected to achieve i) maximal concentrations in the early morning through mid-day, when LID can be troublesome, and ii) lower concentrations in the evening, potentially reducing the negative impact of amantadine on sleep. This pharmacokinetic profile could enable higher doses to be tolerated with a once-nightly ER formulation than can be tolerated with an immediate-release formulation. The once-nightly dosing regimen may also provide enhanced convenience and compliance. In a previous clinical study, ADS-5102 met its primary endpoint; LID was significantly reduced as measured by the change in UDysRS score over 8 weeks vs. placebo.
NCT01313637
This is a phase III multicenter, randomized, double-blind, placebo-controlled, parallel-group study to evaluate the efficacy and safety of GSK573719/GW642444 Inhalation Powder, GSK573719 Inhalation Powder, GW642444 Inhalation Powder and Placebo when administered once-daily via a Novel Dry Powder Inhaler over a 24-week treatment period in subjects with COPD. Subjects who meet eligibility criteria at Screening (Visit 1) will complete a 7 to14 day run-in period followed by a randomization visit (Visit 2) then a 24-week treatment period. There will be a total of 9 clinic study visits. A follow-up phone contact for adverse event assessment will be conducted approximately one week after the last study visit (Visit 9 or Early Withdrawal). The total duration of subject participation in the study will be approximately 27 weeks. A subset of subjects at selected sites will also perform 24-hour serial spirometry and Holter monitoring during the study and provide serial blood samples for pharmacokinetic analysis. Sparse pharmacokinetic sampling for population pharmacokinetic analyses will be obtained from non-subset subjects. The primary measure of efficacy is clinic visit trough (pre-bronchodilator and pre-dose) FEV1 on Treatment Day 169. Safety will be assessed by adverse events, 12-lead ECGs, vital signs, clinical laboratory tests, and 24 hour Holter monitoring (subset only).
NCT03387345
The purpose of this research was to investigate 5 different formulations of whole grain barley and refined white rice against a control of white bread on post-prandial glycemic response, as well as self-reported hunger/satiety in a randomized cross-over trial.
NCT02152605
This study is a 12-week, multicenter, randomized, double blind, parallel group, placebo-controlled study. The purpose of this study is to replicate the therapeutic benefit of UMEC/VI 62.5/25 microgram (mcg) on health-related quality of life as reflected by St. George's Respiratory Questionnaire (SGRQ) scores and symptoms as reflected by rescue medication use observed in the 6 month placebo controlled study (DB2113373). Lung function will be assessed as it provides an objective measure to support the subjective patient reported outcomes of SGRQ and rescue medication use. The study is intended to provide additional evidence to support the use of UMEC/VI for the maintenance treatment of COPD Approximately 496 subjects will be randomized from approximately 62 centers in order to ensure 422 subjects complete 12 weeks of treatment. Eligible subjects will be randomized to UMEC/VI 62.5/25mcg or placebo in a 1:1 ratio. All treatments will be administered once-daily in the morning via a Dry Powder Inhaler (DPI). There will be a total of 5 clinic visits. The total duration of study participation will be approximately 15 weeks. All subjects will be provided with albuterol/salbutamol to use as needed for the relief of COPD symptoms throughout the run-in and double-blind treatment periods.
NCT00360971
RATIONALE: Growth factors, such as palifermin, may lessen the severity of mucositis, or mouth sores, in patients receiving radiation therapy and chemotherapy for head and neck cancer. It is not yet known whether palifermin is more effective than a placebo in lessening mucositis in patients receiving radiation therapy and chemotherapy for head and neck cancer. PURPOSE: This randomized phase III trial is studying palifermin to see how well it works compared to a placebo in lessening oral mucositis in patients undergoing radiation therapy and chemotherapy for locally advanced head and neck cancer.
NCT00836992
RATIONALE: Gathering information about patients' quality of life during radiation therapy for cancer may help doctors plan the best treatment. PURPOSE: This randomized clinical trial is studying quality of life in patients undergoing radiation therapy for primary lung cancer, head and neck cancer, or gastrointestinal cancer.
NCT01777334
The purpose of this 24 week study is to evaluate the spirometric lung function effect (trough FEV1) of Umeclidinium/Vilanterol 62.5/25 once daily compared to Tiotropium 18 mcg once daily along with safety assessments in subjects with COPD.
NCT00259909
The aim of the study is to develop a new patient-reported outcome (PRO) questionnaire measuring the impact of an acute exacerbation on daily lives of patients with chronic obstructive pulmonary disease (COPD). This questionnaire will aim to detect an acute exacerbation and resolution of exacerbation from the patient's perspective. At a later stage of development, this questionnaire will be able to measure the effect of anti bacterials in the treatment of acute exacerbations of COPD (AECOPD). This study will evaluate the factor structure, validity, reliability, and responsiveness of the GSK questionnaire in subjects who experience acute exacerbations of their COPD.
NCT00323284
The purpose of this study is to evaluate the safety and efficacy of the iStent trabecular micro-bypass stent in reducing intraocular pressure (IOP) in subjects with open-angle glaucoma or ocular hypertension and co-existing cataract.
NCT00789958
RATIONALE: Drugs used in chemotherapy, such as capecitabine and gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Radiation therapy uses high-energy x-rays to kill tumor cells. Specialized radiation therapy that delivers a high dose of radiation directly to the tumor may kill more tumor cells and cause less damage to normal tissue. Giving more than one drug (combination chemotherapy) together with radiation therapy may kill more tumor cells. PURPOSE: This phase II trial is studying how well giving capecitabine together with gemcitabine followed by capecitabine and radiation therapy works in treating patients with cholangiocarcinoma of the gallbladder or bile duct.
NCT02487498
The purpose of this study is to demonstrate that the efficacy of the combination product QVA149 is similar to the efficacy of the combination product umeclidinium/vilanterol on a pre-specified endpoint of FEV1 AUC0-24h while maintaining an acceptable safety profile.
NCT01301456
The primary objective of this study is to evaluate the safety and tolerability of PF-04856883 (CVX-096) in adult female subjects with Type 2 diabetes mellitus on high dose of metformin.
NCT02164539
The purpose of this study is to evaluate the dose-response of 4 doses of umeclidinium bromide in combination with fluticasone furoate compared with fluticasone furoate monotherapy in chronic obstructive pulmonary disease participants with an asthmatic component. The fluticasone furoate/umeclidinium bromide treatments will also be compared to the once-daily inhaled corticosteroid/long-acting beta agonist combination fluticasone furoate/vilanterol.
NCT01323621
The purpose of this study is to evaluate the 24-hour spirometry effect (FEV1) of FF/VI 100/25mcg once daily compared with Fluticasone Propionate/Salmeterol 250/50mcg twice daily over a 12-week treatment period in subjects with COPD.
NCT02105974
This is a Phase IIIa, multicenter, randomized, stratified (reversibility status), double-blind, parallel-group study to evaluate the efficacy and safety of FF/VI 100/25 micrograms (mcg) once daily (QD) compared with VI 25 mcg QD, administered in the morning via the ELLIPTA™ inhaler. The primary objective of this study is to evaluate the contribution on lung function (as measured by trough forced expiratory volume in one second \[FEV1\]) of FF 100 mcg to the FF/VI 100/25 mcg QD combination by comparison of the latter with VI 25 mcg QD and the safety of FF/VI 100/25 mcg over a 12-week treatment period in subjects with COPD. ELLIPTA™ is a registered trademark of GlaxoSmithKline.
NCT01061671
To determine the effect of daily administration of 40 mgms simvastatin taken for at least 12 months (range 12-36 months) on the frequency of exacerbations of chronic obstructive lung disease (COPD) in patients with moderate to severe COPD who are prone to exacerbations and do not have other indications for statin treatment.
NCT00253630
This phase II trial is studying how well vorinostat works in treating patients with relapsed or refractory indolent non-Hodgkin's lymphoma. Drugs used in chemotherapy, such as vorinostat, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Vorinostat may also stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
