NCT ID: NCT03961997 Not yet recruiting - Healthy Volunteers Clinical Trials

Effect of Multiple Doses of Modafinil on the Pharmacokinetics of Single Dose Lorlatinib in Healthy Participants

Start date: June 11, 2019
Phase: Phase 1
Study type: Interventional

The primary purpose of the study is to characterize the safety profile of lorlatinib in the presence of a moderate CYP3A4/5 inducer, modafinil. In another drug-drug interaction study for lorlatinib coadministered with a strong CYP3A4/5 inducer, rifampin, all participants experienced increases in liver enzymes after receiving the combination of a single dose lorlatinib (100 mg) with rifampin (600 mg daily (QD)) after multiple doses of rifampin. The AST and ALT continued to increase over the next 24-48 hours, but recovered below the upper limit of normal for all participants upon discontinuation of rifampin. We hypothesize the combination of lorlatinib with the moderate CYP3A inducer modafinil will not have a safety findings related to liver enzyme elevation similar to what occurred in the study with rifampin and lorlatinib.

NCT ID: NCT03958084 Recruiting - Healthy Clinical Trials

Effect of Therapeutic Techniques on Leg Stretching in Healthy Subjects

Start date: April 20, 2019
Phase: N/A
Study type: Interventional

There are physiotherapy techniques, known as lumbar mobilization, proprioceptive neuromuscular facilitation, massage therapy, windsheets and foam roller that present good results in stretching the legs. This study aims to evaluate which of these techniques has a better result in leg stretching. It is believed that massage therapy and lumbar mobilization will provide better results.

NCT ID: NCT03800342 Completed - Fatigue Clinical Trials

Recovery, Fatigability, and Proteomic Response to Aerobic Exercise Training in Healthy Individuals

Start date: January 22, 2019
Phase: N/A
Study type: Interventional

The purpose of this protocol is to investigate the role of expired non-metabolic carbon dioxide in the relationship between fatigability and recovery and the response to aerobic exercise training in healthy individuals. Both fatigability and recovery are profoundly influenced by mitochondrial energetics which can be inhibited by ionic by-product accumulation during exercise. Buffering mechanisms of these fatigue-inducing ions releases non-metabolic carbon dioxide (CO2) that can be measured as expired CO2 (VCO2) during cardiopulmonary exercise testing (CPET), however the role of non-metabolic VCO2 in the relationship between fatigability and recovery has yet to be investigated. Furthermore, this study aims to identify the how the patterns of proteins in healthy individuals respond to aerobic exercise training (e.g. stationary cycling) over approximately one month. The underlying mechanisms of recovery after physical activity, including mechanisms or biological pathways that could be highlighted by analysis of proteins in urine, could add to scientific knowledge regarding physical activity tolerance and potential exercise interventions. This knowledge could eventually assist with designing precise and personalized exercise interventions to improve physical activity performance. The investigators hypothesize that 1) non-metabolic CO2 will be at least moderately associated with the inverse relationship between fatigability and recovery; and 2) highly active adults, compared to sedentary individuals, will exhibit differential proteomic patterns in response to an initial acute bout and subsequent repeated bouts of aerobic exercise.

NCT ID: NCT03728114 Not yet recruiting - Adult Clinical Trials

Effects of RIC on Cognitive Function and Blood Oxygen Levels in Unacclimatized Adult at High Altitude

Start date: November 2018
Phase: N/A
Study type: Interventional

Several studies have shown cognitive impairment such as memory, perception and learning skill during ascent to high altitudes. However, few studies have directly investigated the effect of high altitudes exposure on attention—a high-level cognitive function. Remote ischemic conditioning (RIC) is a noninvasive and easy‐to‐use neuroprotective strategy, It has been proven to be an effective strategy for neuroprotection in ischemic stroke and chronic cerebral ischemia patients.

NCT ID: NCT03713931 Recruiting - COPD Clinical Trials

PUMA Implementation 2

Start date: November 14, 2018
Study type: Observational [Patient Registry]

COPD is underdiagnosed and spirometry is not widely available in primary care settings. This study explore the value of PUMA´s questionnaire in a case finding strategy to detect patients to perform spirometry in a real world scenario of primary care health venues.

NCT ID: NCT03698799 Recruiting - Clinical trials for Perioperative/Postoperative Complications

Adherence to LPV in SICU and Associated Clinical Outcomes

Start date: April 9, 2018
Study type: Observational

Lung Protective Ventilation strategy (LPV) with low tidal volume and adequate positive end-expiratory pressure is recommended for not only patients with acute respiratory distress syndrome (ARDS) but also those without ARDS too. From previous studies, adherence to LPV strategy reported is only 40% and data is limited in surgical patients. The investigators aim to describe ventilation management and find out the adherence rate to LPV strategy applied to surgical patients admitted to the surgical intensive care unit (SICU) and their associated outcomes.

NCT ID: NCT03645616 Completed - Low Back Pain Clinical Trials

Reliability of Function Tests for People With Back Pain.

Start date: June 1, 2018
Phase: N/A
Study type: Interventional

Back pain is often accompanied by changes in function. The performance of individuals with their backs on their wills may become more functional. It is believed that the test will present good to excellent reliability in individuals with chronic back pain. From this, it can be used in the clinic to verify the functional capacity of these individuals.

NCT ID: NCT03632226 Active, not recruiting - Pharmacokinetics Clinical Trials

Evaluation of a Novel PET Radioligand to Image OGA

Start date: May 2, 2016
Study type: Observational

Background: O-GlcNAcase (OGA) is a brain enzyme. It may play a role in brain disorders like Alzheimer s disease. Researchers want to see if a new drug can be used with positron emission tomography (PET) scans to show OGA better. Researchers want to learn more about how it acts in healthy people. Objectives: To test if the new drug [18F]OGA-1 can measure its receptor. To determine whether the same results occur when scanning a person twice. Eligibility: Healthy adults age 18 and older who are already enrolled in a separate protocol. Design: Some participants will have 1 whole-body PET scan during one 4-hour visit to the clinic. Some will have 2-3 brain scans (PET and MRI) over 2-3 days. For the PET scan, a needle will guide a thin plastic tube (IV catheter) into an arm vein. A small amount of radioactive chemical will be injected through the catheter. The needle will be removed. Only the catheter will be left in the vein. Another IV catheter may be placed to draw blood. Blood pressure, heart rate, and breathing rate will be measured. Participants will have an electrocardiogram. Participants will lie on a bed that slides in and out of the donut-shaped scanner. The scan will last 2-3 hours. For brain PET scan, participants will wear a plastic mask to keep their head still. For magnetic resonance imaging (MRI) scan, participants will lie on a table. The table slides in and out of the MRI scanner. This is a metal cylinder in a strong magnetic field. Participants will be in the scanner up to 1 hour.
