Filter by:This is a first-in-human, phase 1, single centre, placebo-controlled, double-blind, single ascending dose study of LEVI-04 in heathy volunteers and osteoarthritis patients (with pain attributed to osteoarthritis of the knee)
Background: Little is known about the time it takes for nerve signals to go from one area of the brain to another. Using advanced methods for brain research, researchers want to look at the time it takes to send messages between different brain areas. They also want to develop new tests. Objectives: To develop tests to measure the sizes of nerve fibers in the peripheral nerve system and in the brain. Also to find out the different speeds that information travels in nerve fibers. Eligibility: Healthy, right-handed people ages 18-70 Design: Participants will be screened with medical history and a physical exam. Participants will have up to 7 visits depending on the tests they choose. Visits last about 2-4 hours and may involve the following tests: - Physical exam - Urine tests - Magnetic resonance imaging (MRI). Participants lie on a table that slides into a scanner. They will be in the scanner for up to 1 hour. For some scans, sensors are placed on the skin. They will get earplugs for loud noises. - Small, sticky pads on the skin will electrically stimulate nerves in the forearm. - Transcranial magnetic stimulation (TMS). A wire coil will be held to the scalp. A brief electrical current passes through the coil to affect brain activity. - Electroencephalography. TMS will be given to the brain. Small electrodes on the scalp measure brain activity. Participants may do small tasks. - Electrodes on the scalp will send an electrical current to the brain. - A cone with magnetic detectors will be lowered onto the head to record brain activity. Participants will perform various tasks.
This study will be a single center, open-label, 2-period, fixed-sequence, Phase 1 drug-drug interaction study in healthy subjects. The primary purpose of this study is to evaluate the effect of itraconazole on the PK of ipatasertib and its primary metabolite (G-037720).
The primary objective of this study is to evaluate the safety and tolerability of single ascending doses of subcutaneous (SC) injections of RO7049665 in healthy volunteers. In addition, pharmacokinetics (PK) of RO7049665, the effects of single doses of RO7049665 on regulatory T-cells as well as the single dose immunogenicity of RO7049665 will be evaluated. This trial plans to evaluate approximately seven single dose-levels of RO7049665 or matching-placebo during dose-escalation in approximately 40 participants.
to evaluate the effect of the PPI (rabeprazole) on the PK of a potential commercial tablet formulation of palbociclib
The purpose of this study is to evaluate the safety, tolerability, and pharmacokinetics of single ascending doses of PF-06852231 after first-time administration to healthy adult subjects. The safety, tolerability, and pharmacokinetics of an active metabolite (PF-06892787) will also be evaluated in this study.
This is an open-label, single centre exploratory study to analyse brain exposure of AZD1390 in healthy volunteer males.
The purpose of this study is to evaluate the pharmacokinetics and bioequivalence of Ritonavir tablet 100 mg versus NORVIR 100 mg tablet in healthy Chinese adult participants under fasting condition.
This is a single-dose, randomized, two-period cross-over study with 72 healthy male and female volunteers. The investigational products will be given (after fasting overnight) at separate visits separated by 7 ± 3 days. Blood for pharmacokinetic analyses will be drawn pre-dose and at 5, 10, 15, 20, 25, 30, 40, 60, 75, 90, 105 minutes, as well as 2, 2.25, 3, 4, 5, 6, 8, and 12 hours after drug administration. Subjects will also be monitored to capture any adverse events that may occur. Bioequivalence will be assessed based on the single-dose pharmacokinetics of paracetamol, guaifenesin and phenylephrine, respectively
Despite the increasing popularity of mindfulness meditation and hypnosis in healthcare and in the general community the underlying neurobiological mechanisms are unclear. The change in the relationship between the self and the conscious experience that they bring about may be crucial. This study aims to identify the neural correlates of self-consciousness in meta-awareness and absorption - using functional Magnetic Resonance Imaging (fMRI) in healthy participants combined with detailed first-person experiential accounts and behavioural tasks. This study will provide important clues about the widely reported effects of mindfulness meditation and hypnosis and shed light on the neural correlates of the conscious experience of self.
