31 Clinical Trials for Various Conditions
This study is designed to test the hypothesis that on an equivalent calorie basis, oat based breakfast cereals do not provide the same satiety benefit. The study will also demonstrate the satiety comparison of the cereals related to product density.
The goal of this placebo-controlled, 3-way crossover study is to determine the acute (24-h) bioavailability and pharmacokinetics of the major phytochemicals found whole barley and oats, as well as their effects on selected measures of antioxidation, inflammation, insulin sensitivity/glucose regulation, and vascular remodeling following challenge by an oral glucose tolerance test (OGTT).
The objectives of this study are the following: 1) to determine the effect of daily consumption of whole grain barley for six week on risk factors of cardiovascular disease compared to a diet low in whole grains, and 2) to compare the effects of daily consumption of whole grain barley to those of whole grain oats for six weeks to determine if the response to these two grains is different.
The objectives of this study are the following: 1) to determine the acute effect of whole grain barley on risk factors of cardiovascular disease compared to a diet low in whole grain, and 2) to compare the effects of whole grain barley to those of whole grain oats to determine if the response to these two grains is similar.
This is a placebo-controlled, crossover study investigating the pharmacokinetic bioavailability of avenanthramides from avenanthramide-enriched oats and their in vivo metabolites in a cohort of healthy, older adults.
This is a Phase 2, randomized, double-blind, placebo-controlled, adaptive, multicenter study to evaluate the efficacy, safety, tolerability, Pharmacodynamics (PD), and Pharmacokinetics (PK) of OATD-01 in the treatment of subjects with active pulmonary sarcoidosis.
This clinical trial evaluates whether an adaptive text-message intervention is useful in helping survivors of colorectal cancers (CRC) eat more whole grain foods and less refined grain foods. Most CRC survivors don't achieve the recommended intakes of whole grains or fiber, even though there is strong evidence that a high-fiber diet rich in whole grains lowers the risk of death from CRC. Dietary interventions are a promising approach for reducing death from CRC, and text message interventions specifically are a promising tool for reaching diverse populations. This trial evaluates a text-message based dietary intervention that continuously adapts message content to be specifically tailored for the participant for increasing whole grain consumption.
The goal of this study is to compare coconut oil and sunflower seed oil derived isosorbide disesters and colloidal oatmeal, and observe their effect on pediatric atopic dermatitis among males and females aged 2-17.

The purpose of this study is to evaluate the effect of single dose intravenous rifampin on the single-dose PK of orally administered TAK-906.
This study will test the safety and efficacy of three topical agents containing oat kernel flour to determine how well they relieve skin dryness and itching related to cancer therapies. Participants will receive a body wash, a body cream, and an anti-itch balm to use at home for 4-6 weeks.
N-acyl-phosphatidylethanolamine (NAPEs) and their active metabolites, N-acyl-ethanolamides (NAEs) are lipid satiety factors that are normally biosynthesized in the intestinal tract in response to food intake. Reduced levels of NAPEs and NAEs have been found in obese individuals, and increasing plasma NAPE and NAEs levels may be beneficial to obese individuals trying to lose weight or to keep off weight gain after losing weight. We have found that oatmeal has large amounts of NAPEs, and based on previous mouse studies, we hypothesize that a single dose of dietary oatmeal is sufficient to double plasma NAE from baseline, possibly inducing satiety and increasing basal metabolic rate. To test this hypothesis, we will feed volunteers a single weight-based serving of oatmeal while monitoring its effects on serum glucose, NAPE and NAE levels as well as on subjective satiety.
This study is to determine if two breakfasts of equivalent calories, an oat based breakfast cereal or a ready-to-eat cereal, provide the same satiety benefits. The study will also determine if the two calorically equivalent oat-based breakfast cereals give different caloric intakes at a lunch meal that participants will eat to their satisfaction.
To test the hypothesis that two 40 gm serving of Oat-based breakfast cereals compared to an equicaloric amount of a ready-to-eat Oat-based breakfast cereal will give greater satiety over the 4 hour period following breakfast.
The objective of this randomized, double-blinded, placebo-controlled, parallel trial is to determine whether consuming avenanthramide-enriched oats daily for 8 weeks on can improve biomarkers of inflammation in older, obese adults.
The purpose of this study is to test the effects of study drug (GSK1605786) on the blood levels of multiple commonly used drugs that are given to measure how your liver breaks down the study drug. These commonly-used drugs are midazolam, pioglitazone, omeprazole, and rosuvastatin which will determine the effect of GSK1605786 on how the body breaks down (metabolizes) these commonly-used drugs. Blood samples for pharmacokinetic analysis of GSK1605786, and two metabolites, \[GSK2635622 (CCX062) and GSK2656694 (CCX304)\] and four probe substrates will be collected over a 24-hour period after administration. Safety will be assessed by the measurement of vital signs, cardiac monitoring, collection of adverse event assessments and laboratory tests.
The purpose of this study is to determine whether opening an occluded infarcted artery 3-28 days after an acute myocardial infarction in high-risk asymptomatic patients reduces the composite endpoint of mortality, recurrent myocardial infarction, and hospitalization for class IV congestive heart failure over an average 2.9-year follow-up with extended follow up for an average of six years. Long term follow-up of patients were completed in March 2010. Final collection of all regulatory documentation was completed June 2011.

The Effects of Successful OSA TreatmENT on Memory and AD BIomarkers in Older AduLts (ESSENTIAL) study is a 5-year, multicenter randomized open-label trial that will screen 400 cognitively normal older adults recruited from well-established sleep clinics at 4 academic medical centers, with newly diagnosed moderate-severe OSA. An expected 200 OSA patients will be then randomized to one of two groups: i) a 3-month OSA treatment by any combination of PAP, OAT, and positional therapy that results in an "effective" AHI4%\< 10/hour and AHI3A\<20/hour (see below); ii) a waitlist control group to receive treatment at the conclusion of the 3-month intervention period. Both groups will continue follow-up for 24 months on stable therapy to determine if sustained improvements in sleep are associated with improvement in cognitive function and AD biomarkers.
Central Asia (CA) represents the most rapidly growing HIV epidemic region worldwide, concentrated in people who inject drugs (PWID) and their sexual partners, and scaling up opioid agonist therapies (OAT) in this region is the most cost-effective strategy to prevent new HIV infections, and more effective when combined with antiretroviral therapy (ART). The investigators propose to use the Network for the Improvement of Addiction Treatment (NIATx) implementation strategy to scale-up OAT in three diverse Central Asian countries (Kazakhstan, Kyrgyzstan, Tajikistan) and guided by the Exploration-Planning-Implementation-Sustainment (EPIS) framework. Understanding the trajectories of implementation and scale-up in this context may emerge through creating communities of practice, especially when cohesion and competence evolves, and may guide other healthcare delivery challenges in the region (e.g., HIV, TB); as well as build important regional expertise and understanding implementation trajectories should help support OAT program sustainability.
The main objective of this study is to test the ability of an allograft plug to provide a successful repair of an osteochondral defect left at the harvest site during OATS procedure.
The process of drug elimination that occurs within the kidneys is complex, and involves filtration, secretion and absorptive mechanisms. Many drugs, metabolites and toxins, including organic anions and cations, rely on renal mechanisms for elimination from the body. Failure to recognize the contribution of renal mechanisms involved in drug elimination during the drug development process can result in drug interactions or toxicity in clinical trials. This is increasingly important due to the use of OAT1 inhibitors such as probenecid that are being used in adjuvant treatment regimens. Thus, in order to more fully understand the effects renal disease, drugs and nephrotoxins on the renal transport pathways of tubular secretion in humans, novel approaches that incorporate both in vitro (experimental) as well as clinical observations (clinical trial), also called in-vitro/in-vivo correlations (IVIVC) need to be developed. These methods can then be used to identify and evaluate specific kidney "probe" drugs that undergo extensive tubular secretion. Such approaches are needed to characterize drug clearance by tubular mechanisms and to identify potentially significant drug-drug interactions prior to exposure to patients in Phase 2 and 3 clinical trials. This investigator-initiated pilot project aims to determine the pharmacokinetics of selected FDA-approved compounds (PAH, iothalamate) for use in IVIVC model development. The proposed research is innovative, because it involves a translational approach to development of an IVIVC model applied to renal drug clearance. It is our expectation that the resultant approach will further our understanding of pharmacogenomics, inter-subject variability and renal drug clearance. This approach will generate important new information regarding in vitro drug-drug interactions in light of many new and potent OAT1 blocking agents being introduced for the treatment of human diseases. In future studies, we hope to fully characterize the effects of diseases such as diabetes, hypertension, and nephropathy on renal drug transport mechanisms using IVIVC models. We expect that results from this NIH-funded study will provide needed preliminary data to design future pharmacogenomic and drug interaction studies in humans.
This is a prospective, non-randomized, phase I study design evaluating the in vivo activities and expression of OCT1 and BCRP in mammary gland of lactating women at three time points postpartum.
A Phase II Multicenter, Open-Label, Single Arm Study to Determine the Efficacy, Safety and Tolerability of AZD2811 and Durvalumab Combination as Maintenance Therapy After Induction with Platinum-Based Chemotherapy Combined with Durvalumab, for the First-Line Treatment of Patients with Extensive Stage Small-Cell Lung Cancer.
Researchers in this study want to learn how the study drug BAY1817080 interacts with another drug called rosuvastatin (brand name: Crestor) and affects the way the body absorbs, distributes and excretes rosuvastatin in healthy adult male and female participants (drug-drug interaction study). The study drug BAY1817080 is a new drug under development with a goal to suppress pain and chronic cough. It works by binding to and blocking proteins related to pain in the body. Rosuvastatin is an approved and marketed drug to lower high levels of "bad" cholesterol (a waxy, fat-like substance found in blood). Both drugs interact with the same proteins (molecules) in the human body, and as a result, the study drug may affect the way rosuvastatin is taken up and used by the body when applied together. Participants in this study will be asked to visit the clinic 3 times over a period of 3 to 4 weeks. Each participant will receive rosuvastatin tablets twice with at least 11 days in between and the study drug tablets twice daily for 14 days. Blood samples will be taken from the participants to measure the blood levels of rosuvastatin.
This is a phase III, randomized, open-label, multicenter, global study to determine the efficacy and safety of combining durvalumab ± tremelimumab with platinum based chemotherapy (EP) followed by durvalumab ± tremelimumab maintenance therapy versus EP alone as first-line treatment in patients with extensive-stage small-cell lung cancer
This study will determine whether using a genetic test (for the SLCO1B1 gene) can help patients and providers choose the right type and dose of cholesterol-lowering statin medications to lower the risk of cardiovascular disease, while minimizing the muscle pain side effects that sometimes occur with statins.
Background: - Prostate cancer is the most common cancer type among men. Some prostate cancers respond to hormonal therapy. However, some cell characteristics of other prostate cancers cause it not to respond as well to these therapies. Researchers want to see if gadoxetate, a contrast agent used to help identify damaged liver tissue, can help tell these types of prostate cancer apart. It may be able to identify if a man has a type of prostate cancer for which hormone therapy may not work as well. Objectives: - To see if gadoxetate can help identify different types of prostate cancers during imaging studies. Eligibility: - Men at least 18 years of age who have prostate cancer. Participants will be having surgery to either remove the prostate or take tumor tissue samples. Design: * Participants will be screened with a physical exam and medical history. Blood samples will be collected. * Participants will have a magnetic resonance imaging (MRI) scan of the lower torso. They will receive gadoxetate during the MRI scan. * Participants who have surgery will have a sample of their tumor cells collected. Those who have a biopsy will provide cells from this biopsy for study. * Treatment will not be provided as part of this study.
This multi-center study is designed to evaluate the ability of intended lay users (patients on oral anticoagulation therapy, OAT, or their caregivers) to 1) operate the INRatio Prothrombin Time (PT) Monitoring System utilizing the INRatio test strip newly designed for low sample volume and heparin insensitivity, and 2) obtain accurate results for the quantitative determination of International Normalized Ratio (INR) when self-testing using fingerstick capillary blood. Patients will be trained by their healthcare provider using the instructions for use and product labeling provided. The accuracy of the patient INR results will be assessed by comparison to the INR results obtained by the site's trained healthcare professional using the same INRatio system (from a separate fingerstick collected from the same patient at the point-of-care), and with the INR results obtained on venous plasma obtained from the same patient and analyzed at a central laboratory with the Sysmex CA-560 System INR reference method.
This is a multi-center study designed to evaluate the heparin insensitivity of the INRatio Prothrombin Time (PT) Monitoring System, utilizing an INRatio test strip additionally modified for low sample volume. The INRatio test strip is used for the quantitative determination of PT and International Normalized Ratio (INR) results in fingerstick blood from subjects on oral anticoagulation therapy (OAT) with warfarin. This study is designed to evaluate the accuracy of the modified INRatio test strip during heparin-warfarin bridge therapy with unfractionated heparin (UH) or low molecular weight heparin (LMWH), such as enoxaparin or dalteparin. These INR results will be compared to the INR results obtained on plasma from the same subjects as analyzed at a central laboratory with the heparin-insensitive reference method: the Sysmex CA-560 System. The levels of UH or LMWH in the plasma samples will be assessed using activated partial thromboplastin time (aPTT) and anti-factor-Xa assays respectively.
