Filter by:Parts A and B: The primary objective of this study is to evaluate the safety and tolerability of single and multiple ascending oral doses of BIIB113 in healthy participants. The secondary objectives of this study are to evaluate the single and multiple oral dose pharmacokinetic (PK) profile of BIIB113 in healthy participants and to evaluate the effect of food on the single oral dose of BIIB113 in healthy participants of Part A cohort 3. Part C: The primary objectives of this study are to evaluate the safety and tolerability of single and multiple ascending oral doses of BIIB113 in healthy participants and to determine target occupancy (TO) as measured by O-GlcNAcase-Positron Emission Tomography (OGA-PET) of single and multiple oral doses of BIIB113 in healthy participants.
This will be an open-label, randomized, 2-treatment, 2-period, crossover single-dose study in approximately 134 healthy adult participants. Participants will be randomized into 2 sequences of treatment as described in the following table of Intervention Groups and Duration.
This is a four-arm, randomized, crossover, placebo and active controlled study to evaluate of the effect of therapeutic and supratherapeutic doses of CTP-543 on the QT/QTc intervals in healthy volunteers
Background: This first-in-human study will investigate the safety and tolerability of single and multiple doses of nebulised SoftOx Inhalation Solution (SIS) delivered via a jet nebuliser to healthy subjects. Objectives: The objective of the current study is to assess the safety and tolerability of single and multiple ascending doses of nebulised SIS in healthy subjects. Eligibility: Subjects are eligible to participate in this study if they are healthy, between 18 and 55 years of age, and have a Body Mass Index (BMI) of ≥ 18.5 and ≤ 29.9 kg/m2. Subjects are not eligible to participate in this study if they have recently participated in another clinical trial or have donated blood, have a medical condition or a history of drug hypersensitivity, are using concomitant medication, or have a positive drugs of abuse test. Design: A randomised, double-blind, and placebo-controlled trial. Subjects will be enrolled into one of three single dose groups or into one of four multiple dose groups. The two first multiple dose groups will be dosed once daily (OD) for five days. The two last multiple dose groups will be dosed twice daily (BID) for four days plus a morning dose on Day 5, or four times daily (QID) for four days plus a morning dose on Day 5, respectively. The investigational medicinal product (SIS or placebo; IMP) will be delivered via a jet nebuliser and inhaled through a mask over a period of up to 15 minutes. Each treatment group will comprise eight subjects who will be randomised to receive SIS or placebo in a 3:1 ratio. A Safety Monitoring Committee (SMC) will review the safety and tolerability data from all preceding groups and decide whether the planned next dose regimen is acceptable prior to initiating the dosing in a new dose group. The dose to be administered in the multiple dose groups will depend on the results obtained in the single dose groups and will be decided by the SMC. The dose tested in the first multiple dose group will be the second highest well-tolerated single dose or lower.
This is a first-in-human study to evaluate the safety and tolerability of single ascending doses of IW-3300. The study drug will be administered rectally as a low-volume (20 mL) enema. Study participants will be randomized in a 3:1 ratio to receive a single dose of IW-3300 or placebo. Up to 5 different doses of IW-3300 will be studied. Safety reviews will be conducted before proceeding to each higher dose.
This is a Phase 1, multi-center, randomized, double-blinded, placebo-controlled study to assess the safety, tolerability, and pharmacokinetics (PK) of IGM-6268 administered intranasally and intraorally in healthy volunteers and in outpatients with mild-moderate COVID-19. IGM-6268 or placebo will be administered by intranasal + intraoral spray using a Teleflex Mucosal Atomization Device Nasal™ Intranasal Mucosal Atomization Device once, or once or twice each day for 5 days.
In the course of the clinical study, the pharmacokinetics, pharmacodynamics, safety and tolerability of Dimolegin (DD217) 10 mg enteric-coated tablets after single administration to healthy volunteers at increasing doses were studied. 24 volunteers participated in the study. The randomization procedure was carried out for 24 volunteers selected at screening. In Group 1 6 volunteers were randomized , in Group 2 6 volunteers were randomized, and in Group 3 12 volunteers were enrolled. Group 1 volunteers took the study drug at a dose of 20 mg once, group 2 volunteers took the study drug at a dose of 40 mg once, and group 3 volunteers took the study drug at a dose of 60 mg once.
This is a study of participants that will receive intravenous (IV) infusions of oxytocin (naturally occurring hormone that is made by the brain). In this study healthy participants will be recruited for the study. There will be 3 study related visits: 1) screening and informed consent 2) study medication infusions and thermal heat testing 3) study medication infusions and thermal heat testing. During study visits 2 and 3 an IV catheter will be placed and a dose of oxytocin or placebo (inactive solution) will be given over a 10 minute period; 1 hour after the first infusion, a second 10 minute infusion of oxytocin will be administered. Investigators will perform some tests to evaluate how oxytocin changes perceptions of the skin. Investigators will study a painful perception by placing a probe on the skin of the side of lower leg and heating it up to 113-117 degrees Fahrenheit (F) (45-47 degrees Celsius (C)) for 5 minutes. Each participant will score any pain that is experienced on a 0 to 10 scale for each minute during the heating period. Most people find that pain rises during the 5 minutes, but remains mild; usually less than 5 on the 0 to 10 pain scale. The temperature of the 5 minute heating will be determined according to the participants pain rating during the screening visit. The primary objective of the study is to determine the dose response of IV oxytocin for analgesia (pain relief) to experimental heat pain.
In this study biomarkers in the blood after exposure to heparin in the fasted state or after a high-fat meal will be investigated. Heparin will be administered as an intravenous (iv) injection (injection directly in a blood vessel). In this study, the effects of administration of heparin will be compared with the effects of administration of normal saline which will also be administered as an iv injection.
