Filter by:The safety, tolerability, and pharmacokinetics(PK)/pharmacodynamics (PD) of DA-3031 (PEG-G-CSF) following a single dose delivered by subcutaneous (SC) injection were investigated in healthy volunteers. PK/PD of filgrastim (Dong-A) following repeated dose delivered by SC injection were investigated in healthy volunteers. PK/PD from a single dose of DA-3031 and repeated dose of filgrastim (Dong-A) were compared.
This is a study to investigate the process by which ABT-126 is absorbed, distributed, metabolized and eliminated by the body of a healthy volunteer.
The purpose of this study is to determine whether rebreathing for a short time (a bit like breathing into a paper bag) will stimulate faster breathing and thus make the giving of Oxygen more effective. The hypothesis is that the investigators method (rebreathing) will be faster than the current method of administering Oxygen.
The major aim of this study is to investigate and compare the drug amount delivered to the body after sequential application of 2 rotigotine transdermal patches from 2 different manufacturing sites.
In this study the investigators will determine whether there is any effect of GSK1014802 on ambulatory blood pressure. This will be a randomized, double-blind, placebo-controlled, repeat dose, 2 period cross-over study conducted in healthy male and female subjects. Approximately 60 subjects will be randomised to receive GSK1014802 400 mg bid and placebo for 36 days with at least 1 week between treatment sessions. A follow-up will occur 7-14 days after the last dose.
The purpose of this study is to determine genetic factors that affect responses to niacin therapy and endotoxemia in healthy volunteers.
The bioavailability of the oral disintegrating tablet formulations given without water will be similar to an equivalent dose of the standard oral tablet given with water.
Recent reports showed that the opioid buprenorphine is a very potent sodium channel blocker. Buprenorphine not only exerts a strong antinociception, but also a long lasting antihyperalgesic effect. This antihyperalgesic effect is not observed for other clinically employed opioids but is common for local anaesthetics. The principal aim of the study is to compare the speed of onset and the time of recovery of motor blockage achieved by lidocaine and buprenorphine, respectively. The investigators hypothesize that the blocking capacity of buprenorphine is equal to the one of lidocaine.
The study will investigate how a new formulation of the study drug is absorbed, metabolised and distributed through the body, as well as its safety and tolerability in higher doses when given as single and multiple doses and as a single dose in the presence and absence of naproxen.
Background: - Direct current (DC) brain polarization is a technique in which very weak electricity is applied to the head. Doctors have used DC polarization for many years on patients and healthy people with no known serious side effects. Earlier, researchers found that DC polarization can temporarily improve the ability of healthy people to think of certain words. - A disadvantage of existing methods of DC polarization is that they use large electrodes and the current spreads over a large area of the brain. This makes it difficult to target particular brain areas. High-density DC polarization uses several small electrodes to focus the current in a small area of the brain. This study will test high-density DC polarization for the first time in humans. Objectives: - To see how well high-density direct current polarization works in the brain. - To test a new method of performing direct current brain polarization. Eligibility: - Healthy, right-handed adults, ages 18 and older, who have no history of neurological or psychiatric illnesses. Design: - After an initial screening visit with clinical examination, participants may be assigned to one or both experiments of the study. - Experiment 1: Participants will have electrodes placed on the left side of their heads, and will be asked to say aloud as many words as they can think of that begin with certain letters. After the high-density DC polarization current is turned on and run for 10 minutes, participants will say words beginning with a different set of letters and perform reaction time and thinking speed tests. Some participants will receive real polarization and others will not, although all participants will be told that they are receiving the polarization. - Experiment 2: Participants will have DC brain polarization performed with transcranial magnetic stimulation (TMS), which uses magnetic pulses to activate nerve cells in the brain. We will use TMS to help us understand how far the effect of DC polarization spreads in the brain. After attaching electrodes to a point on the scalp above the ear, researchers will give about 50 TMS pulses to five different places near this area. These pulses will produce some painless muscle twitches in the hand or arm. The TMS pulses will be followed by the DC brain polarization, and then by another set of TMS pulses to see if there are any differences in muscle response.
