NCT ID: NCT03950856 Completed - Clinical trials for Pneumococcal Infections

Lot-to-Lot Consistency of V114 in Healthy Adults (V114-020)

PNEU-TRUE
Start date: June 12, 2019
Phase: Phase 3
Study type: Interventional

The primary objectives are to evaluate the safety and tolerability of V114 and to compare the serotype-specific opsonophagocytic activity (OPA) geometric mean titers (GMTs) across 3 different lots of V114. The primary hypothesis is that all 3 lots of V114 are equivalent as measured by the serotype-specific OPA GMTs for 15 serotypes in V114 at 30 days postvaccination.

NCT ID: NCT03950245 Completed - Bariatric Surgery Clinical Trials

Incretin Hormone Antagonism After Bariatric Surgery

INCA-BAR
Start date: July 1, 2019
Phase: N/A
Study type: Interventional

Using the glucagon-like peptide-1 (GLP-1) antagonist exendin(9-39) and the glucose-dependent insulinotropic peptide (GIP) antagonist GIP(3-30), the purpose of this study is to clarify the importance of endogenous GLP-1 and GIP for postprandial glucose metabolism after RYGB and SG in subjects with normal glucose tolerance. We hypothesize that GLP-1 is more important after RYGB, and GIP is more important after SG, for postprandial glucose tolerance and beta-cell function. A group of un-operated subjects with normal glucose tolerance will serve as controls.

NCT ID: NCT03949075 Completed - Exercise Clinical Trials

Impact of Angiotensin Converting Enzyme Activity on Exercise Training Sensitivity

Start date: May 15, 2019
Phase: N/A
Study type: Interventional

The phenotype based on the insertion/deletion (I/D) polymorphism of the human angiotensin converting enzyme (ACE) gene has been associated with individual training response. Briefly, intervention studies have demonstrated an 11-fold greater training-induced improvement in muscular endurance for ACE I/I homozygotes compared to ACE D/D homozygotes. Importantly, the ACE I/D polymorphism causes large inter-individual differences in serum ACE activity. Because the ACE D/D genotype is characterized by high plasma ACE activity and potentially blunted endurance exercise training response, it appears likely that ACE inhibitors (ACEi) have the potential to improve the outcome of exercise training for ACE D/D homozygotes. Thus, in the present study the investigators apply a randomized double-blind placebo-controlled longitudinal design to investigate whether pharmacological inhibition of ACE activity can amplify the exercise training response in healthy humans carrying either the ACE D/D or ACE I/I genotype. The study hypothesis is that inhibition of ACE activity in healthy humans with the ACE D/D genotype will amplify the health beneficial effects of exercise training while this is not the case in ACE I/I homozygotes.

NCT ID: NCT03946956 Completed - Vascular Diseases Clinical Trials

Fighting Social Inequality in Cardiovascular Health I

FISICH-I
Start date: August 1, 2017
Phase: N/A
Study type: Interventional

This study attempts to reduce social inequality in cardiovascular health by performing an interventional screening trial on how best to decrease cardiovascular disease (CVD) among people with low social status

NCT ID: NCT03945370 Completed - McArdle Disease Clinical Trials

Oral Ketone Body Supplementation in Patients With McArdle Disease

GSDV
Start date: May 6, 2019
Phase: N/A
Study type: Interventional

McArdle disease, glycogen storage disease type V, is a rare metabolic disease. Affected individuals are unable to utilize sugar stored as glycogen in muscle. Investigators hypothesize that ketones can be an alternative fuel substrate for skeletal muscle when muscle glycogenolysis is blocked as in McArdle disease. In this study investigators will investigate the immediate effects of an oral supplementation of exogenous ketone bodies (poly-hydroxybuturate) on exercise capacity in patients with metabolic myopathies, compared with a placebo drink.

NCT ID: NCT03945188 Completed - Ulcerative Colitis Clinical Trials

Etrasimod Versus Placebo for the Treatment of Moderately to Severely Active Ulcerative Colitis

ELEVATE UC 52
Start date: June 13, 2019
Phase: Phase 3
Study type: Interventional

The purpose of this study is to determine whether oral etrasimod is a safe and effective treatment for moderately to severely active ulcerative colitis.

NCT ID: NCT03940456 Completed - Low Back Pain Clinical Trials

Prognostic Factors of Importance on Who Develops Chronic Low Back Pain

Start date: May 8, 2019
Phase:
Study type: Observational

The incidence of low back pain (LBP) is increasing and prognostic factors for developing LBP are unclear. Based on questionnaires, different prognostic factors are being explored over time.

NCT ID: NCT03939767 Completed - Clinical trials for Wet Age-related Macular Degeneration

Assessment of Proactive Treatments in Patients With Wet Age-related Macular Degeneration (wAMD) Which Have Never Undergone Treatment of This Particular Disease

XTEND
Start date: May 12, 2019
Phase:
Study type: Observational

In this observational study researchers want to learn more about changes in visual acuity (clarity of vision) with proactive flexible treatments over time in patients suffering from wet age-related macular degeneration (wAMD) after decision to treat with Aflibercept (Eylea) was made. Wet AMD is an eye disease that progressively destroys the macula, the central portion of the retina, impairing central vision.

NCT ID: NCT03939234 Completed - Clinical trials for Chronic Lymphocytic Leukemia

Peptide Vaccination With PD-L1 and PD-L2 Peptides in Untreated Chronic Lymphatic Leukemia.

Start date: April 26, 2019
Phase: Phase 2
Study type: Interventional

This study is investigating the efficacy of PD-L1 and PD-L2 peptides in untreated CLL patients with unmutated IGHV gene status.

NCT ID: NCT03935841 Completed - Healthy Clinical Trials

Metabolic Differences of an Oral and Intravenous Dose of 3-hydroxybutyrate (3-OHB).

Start date: June 7, 2019
Phase: N/A
Study type: Interventional

An open-labeled intervention study testing healthy, lean, and male volunteers on two separate occasions: 1. blood sampling after consuming 36 gram 3-Hydroxybutyrate (3-OHB) salt. 2. blood sampling while given a variable rate of 3-OHB salt intravenously to replicate the concentrations seen during oral consumption. The primary outcome is differences in insulin concentrations (incremental AUC) 180 minutes after 3-OHB consumed orally vs. intravenously. Secondary outcomes includes iAUC for other gastrointestinal hormones and substrates (Glucagon, GLP-1, GIP, glucose, and 3-OHB) Gastric emptying will be evaluated using 1500 mg Paracetamol consumption before each intervention day. Urine will be analyzed for ketone concentrations/excretion rates.
