Filter by:Suicide attempts are a serious concern worldwide. Currently, existing drugs take about three weeks to show effect on suicidal thoughts and drives. Recent evidence suggests that intravenous Ketamine exerts a rapid effect in suicidal patients, even after a single injection. We aim to examine whether oral Ketamine is a safe and effective treatment in suicidal patients. Following a suicide attempt, patients will be randomized into a group that will be given Ketamine for 21 days and one that will receive placebo, and assessed using questionnaires and brain scans. We expect early improvements in suicide scales in the Ketamine group. As a secondary goal, this study will use IV ketamine in order to access the extent to which the experience of the embodied self mediate different levels of "embodied emotion". A better understanding of these relations will assist in unveiling the cognitive mechanism underlying the therapeutic effect of ketamine
The purpose of this study is to investigate the safety and tolerability of IX-01 after multiple doses, and to determine how the body handles IX-01.
The purpose of this study is to evaluate the absorption, the metabolic pathways (a series of metabolic reactions) and the excretion of JNJ26489112 in healthy male adult participants after administration of a single oral dose of 1000 mg of 14C-JNJ26489112.
The main purpose of this study is to evaluate the safety and how well the body will handle a single dose of increasing strength of study drug LY3050258. Each participant will receive LY3050258 or placebo once, in each of 2 dosing periods. At least 7 days will pass between doses. This study will last approximately 45 days for each participant. Screening is required within 28 days before the start of the study.
FRI could give the opportunity to investigate the possible effect of a lateral posture on airway diameter and airflow distributions. This physiological study in healthy subjects may help to identify the role of positioning as an aid in airway clearance techniques for patients with respiratory diseases.
The purpose of this study is to assess the potential effects of rifampin on the pharmacokinetics (how the drug concentrations change over time) of PCI-32765 in healthy participants.
This study will evaluate the effect of deodorant and antiperspirant use and the presence of underarm hair on the absorption of testosterone. Each participant in this study will receive 6 single doses of 30 milligrams (mg) testosterone applied as a solution to each underarm. There is a minimum one day washout period between each dose. This study will last approximately 24 days not including screening. Screening is required within 30 days prior to the start of the study.
The purpose of the study is to evaluate the effect of steady-state (constant concentration of medication in the blood) rilpivirine on pharmacokinetics (how a single dose of metformin is absorbed in the body, distributed within the body, and removed from the body) of a single dose of metformin, over time, in healthy adult participants.
The purpose of this study is to evaluate effects of steady-state concentrations (constant concentration of medication in the blood) of TMC435 on the single dose pharmacokinetics (what the body does to the medication) of atorvastatin, the active metabolites ortho- and parahydroxylated atorvastatin, simvastatin and the active metabolite simvastatin acid. Plasma hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitory activity after a single dose of atorvastatin or simvastatin, either alone or in combination with TMC435 will be also evaluated.
This study involves 2 parts, Part A and Part B. The purpose of Part A is to evaluate the safety and side effects of LY2940680 in healthy participants. Part A will involve two groups of participants, each taking up to two single doses of LY2940680 at different dose levels. There is a minimum 14 day washout period between each of the participant's doses. The purpose of Part B is to study how much of the study drug, in capsule or tablet form, gets into the bloodstream and how long the body takes to get rid of it. In addition, the effect of food and a proton pump inhibitor (PPI) on LY2940680 will be studied. Part B will involve one group of participants who will take four single doses of 100 milligrams (mg) LY2940680. There is a minimum 7 day washout period between doses. Participants may only enroll in one part. Screening is required within 28 days prior to the start of the study.
