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.
NCT01124422
The objective of this study is to demonstrate that, when added to tiotropium (TIO), fluticasone propionate/salmeterol combination (FSC) DISKUS 250/50 significantly increases exercise endurance time (EET) in the endurance shuttle walk test (ESWT), compared to TIO alone. Male and female subjects at least 40 years of age with a diagnosis of Chronic Obstructive Pulmonary Disease (COPD) are eligible. Subjects will be screened and consented at or during a 6-week (wk) period prior to visit (V)1. The 4-wk run-in period begins immediately after V1, when subjects receive open-label TIO plus as-needed relief inhaler (identical formulations called albuterol in the US and salbutamol in Canada). At V2, subjects will perform an incremental shuttle walk test (ISWT) to establish their maximal walk response. The first ESWT will occur at V3. Subjects must demonstrate an EET of ≤20 min that is reproducible (EET from V3 and V4 varying by ≤2 min). Eligible subjects are then randomized at V5 to either FSC 250/50mcg DISKUS twice daily plus open label TIO 18 mcg daily, or placebo DISKUS twice daily plus open label TIO 18 mcg daily for the 4-wk treatment period. The last study visit is V6. The primary efficacy measure is the difference between the EET at V6 (wk-8) vs. V4 (wk-3; the last ESWT done before randomized study drug is given). Secondary efficacy measures include V6 vs. V4 comparisons in exercise dyspnea scale (EDS), exercise inspiratory capacity (EIC) and cardio-respiratory measurements (CRM), and V6 vs. V5 comparisons in dyspnea related to activities of daily living (baseline dyspnea index and transition dyspnea index interviewer-administered \[BDI-TDI\]) and quality of life (Chronic Respiratory Disease Questionnaire Self-administered Standardized \[CRQ-SAS\]). The safety measure will be an assessment of adverse events. We will also attempt to validate prospectively the minimal clinically-important difference (MCID) for a change in the EET through correlation with dyspnea and quality of life results.
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.
NCT01156142
RATIONALE: Doxepin hydrochloride may be an effective treatment for oral mucositis pain in patients undergoing radiation therapy with or without chemotherapy. PURPOSE: This randomized phase III trial is studying doxepin hydrochloride to see how well it works compared to placebo in treating oral mucositis pain in patients with head and neck cancer undergoing radiation therapy with or without chemotherapy.
NCT02546700
Phase II, randomized, double-blind, placebo-controlled, parallel-group clinical trial of lebrikizumab in participants with COPD and a history of exacerbations who are treated with inhaled corticosteroid (ICS) and at least one long-acting bronchodilator inhaler medication. This study will be conducted to assess the safety, efficacy, and patient-reported outcome (PRO) measures.
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.
NCT02042443
This randomized phase II trial studies how well trametinib or combination chemotherapy works in treating patients with refractory or advanced biliary or gallbladder cancer or that cannot be removed by surgery. Trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as fluorouracil, leucovorin calcium, and capecitabine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving trametinib is more effective than combination chemotherapy in treating patients with biliary or gallbladder cancer.
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.
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.
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.
