Filter by:The aim is to evaluate the electrocardiogram quality signal of the Cardioskin device and compare it with a Holter signal. For that, volunteers subjects will wear the Cardioskin and Holter, non-simultaneously, for about 24 hours. This study is open, and will be carried out according to a cross plan. The trial will include approximately 36-40 subjects between 18 and 70 years old.
Tolvaptan is a new drug that specifically antagonizes the V2-receptor of antidiuretic hormone (ADH) and leads to water diuresis: During acute administration of tolvaptan, the main fear is to induce a too fast increase in plasma sodium concentration and in turn brain damageHowever, the tolvaptan-induced increase in plasma sodium concentration is expected to stimulate thirst, preventing major negative water balance. The investigators hypothesize that tolvaptan-induced increase in plasma osmolality (and sodium concentration) is dependent of thirst adaptation that is influenced by physiological factors, namely age and sex. To address the effect of a single oral administration of tolvaptan at a dosage used during hyponatremia (15 mg) under free water access in healthy volunteers. Primary outcome will be the maximal change in serum sodium concentration within the 6 hours following tolvaptan administration.
This study will investigate the absorption, distribution, metabolism and excretion (ADME) of 14C PF-06651600 and characterize plasma, fecal and urinary radioactivity and identify any metabolites, if possible, of 14C PF-06651600 in humans.
The purpose of this study is to characterize the effect of itraconazole (Part 1) and rifampin (Part 2) on the single-dose pharmacokinetics (PK) of TAK-788 and its active metabolites (AP32960 and AP32914) in healthy adult participants.
Asthma is caused by or worsened by different things in different people. It is because of these differences that not all people with asthma respond the same to all treatments and medicines. If the investigators can better identify the changes in the airways or breathing pipes in patients with asthma, the investigators may be able to help patients make better choices about the medicines or treatments that are most likely to work best for each patient. This research study is about one specific factor that is known to affect asthma in some patients. It involves an increase in the activity of an enzyme that is in people's airways. An enzyme is something that helps a chemical reaction to occur. The enzyme the investigators are studying in this research study is called GSNOR (S-nitrosoglutathione reductase) , and when the activity of this enzyme is increased, the result is that there is less GSNO (S-nitrosoglutathione) . GSNO is a chemical that protects people's airways. The initials stand for S-nitrosoglutathione, (pronounced s-nahy-troh-soh-gloo-tuh-thahy-ohn), and it is naturally produced by the body. It has an important role in regulating respiratory function (breathing) and preventing inflammation (swelling) in the respiratory tract (throat, airways, and lungs). The amount of GSNO found in the body is controlled by the enzyme GSNOR (S-nitrosoglutathione reductase). GSNOR breaks down GSNO. Too much GSNOR leads to low levels of GSNO, and that can cause inflammation (swelling) and loss of airway function in some asthma patients. The only way to measure GSNOR levels currently is with a bronchoscopy procedure where a scope is inserted into the patient's airways, often under sedation. This research study is being done to test the accuracy of another type of test that can be done in the doctor's office, rather than in a procedure area. This non-invasive diagnostic test, called a GSNO Challenge test, may be able to identify which asthma patients have increased activity of the airway enzyme GSNOR. The investigators are also studying the phenotypes (observable traits) in asthma patients with increased levels of GSNOR. If this research study is successful, in the future (after this research study is done). The investigators may be able to offer a cost-effective and non-invasive way to identify patients who have higher GSNOR activity levels and offer personalized treatments. The GSNO Challenge test includes giving an investigational drug to breathe in (inhale). The investigational drug is GSNO. "Investigational" means the drug is not approved by any regulatory agencies including the Food and Drug Administration (FDA), and is still being tested for safety and effectiveness. The research is registered with the FDA, but again the GSNO treatment in this study (administered during the GSNO challenge testing) is not an approved treatment or diagnostic test for asthma.
This is a Phase 1, first-in-human study involving single and multiple oral doses of TS-161 in healthy male and female participants. The safety, tolerability, pharmacokinetics and pharmacodynamics of TS-161 will be evaluated. The study includes 3 parts; Part A (single ascending dose: Cohorts 1 to 5) , Part B (single dose, cerebrospinal fluid [CSF] collection: Cohort 6), and Part C (multiple ascending dose: Cohorts 7 to 9). Participants will be assigned to one of the 9 Cohorts.
This is a 6-part first-in-human study in up to approximately 184 participants. Parts 1 to 5 is in health volunteers and part 6 is in subjects with atopic dermatitis. The purpose of this first-in-human study is to assess the safety and tolerability and pharmacokinetics (PK) of single and multiple doses of LOU064 both as once and twice daily oral administration in healthy volunteers and those with atopic diathesis or atopic dermatitis. This study will also explore the effect of food intake and different drug substance particle sizes on the in vivo disposition of LOU064 in healthy volunteers to guide dosing and formulation development for future clinical trials. The study is registered on CT.Gov with the initiation of part 6 in patients (FPFV in April 2019).
The purpose of this study is to evaluate bioavailability of lanadelumab (SHP643) following a single, 2 milliliter (mL) subcutaneous (SC) dose of 300 milligrams (mg) delivered by prefilled syringe (PFS) or auto injector (AI) in healthy adult participants.
This is a Phase 1, randomized, open label, 2 way crossover drug drug interaction (DDI) study which will evaluate the impact of PF 06835919 on midazolam pharmacokinetics in healthy participants. Participants will be randomized to 1 of 2 treatment sequences as described below. A total of approximately 10 healthy male and/or female participants will be enrolled in this study so that approximately 5 participants will be enrolled into each treatment sequence. In this crossover study, 2 treatments are being assessed.
Background: Inflammation can play a role in diseases like heart disease and rheumatoid arthritis. PET scans can help detect inflammation. Two new drugs may create better PET images. Objective: To see if the drugs [11C]ER176 and [11C]MC1 can help image inflammation. Eligibility: People ages 18 and older with rheumatoid arthritis or idiopathic inflammatory myopathy (IIM). Healthy volunteers enrolled in protocol 01-M-0254 or 17-M-0181 are also needed. Design: Healthy participants will be screened under protocol 01-M-0254 or 17-M-0181. Participants with arthritis or IIM will have a screening visit. This will include: Medical history Physical exam Blood and urine tests Possible CT or X-ray: A machine will take pictures of the body. Healthy participants will have 1 or 2 visits. They may have urine tests. They may take the drug celecoxib by mouth. They will have a PET scan. A small amount of one or both study drugs will be injected through a catheter: A needle will guide a thin plastic tube into an arm vein. Another catheter will draw blood. They will like on a bed that slides into a machine. Their vital signs and heart activity will be measured. Participants with arthritis will have up to 2 visits after screening. They may take celecoxib and have PET scans. Participants with IIM will have up to 3 visits after screening. At 1 or 2 visits, they will take celecoxib and have PET scans. They will have 1 visit where they have an MRI: They will lie on a table that slides into a machine. The machine takes pictures of the body.
