Ketamine Treatment Options in United Kingdom

A Phase 1, Single-centre, Double-blind, Placebo controlled Crossover Study to Assess the pharmacoMRI Effects of AUT00206 in Healthy Male Participants Read Less

The primary objective of this study is: • To determine the effects of ketamine, which blocks the ion-channel gated by the NMDA receptor, on performance of cognitive tasks and the extent to which these effects can be reversed by the dopamine receptor antagonist, risperidone. The secondary objectives of this study are: * To establish whether patients with schizophrenia are able to reliably complete the biomarker test battery and to assess whether their responses are similar to healthy volunteers treated with ketamine. * To establish a multi-site recruitment and assessment capacity based on shared Standard Operating Procedures across three study centres.

The main aim of this research is to ascertain whether Ketamine would be a more effective anaesthetic for Electroconvulsive Therapy (ECT) than the standard anaesthetic. In doing so the investigators aim to examine the effect of ketamine on ratings of depressive symptoms, the number of required ECT treatments, and the effect of this anaesthetic on memory. Read Less

The purpose of this study is to determine the effect of a single dose infusion of AZD 6765 compared with placebo and ketamine on the blood oxygen level dependent signal using fMRI (functional Magnetic Resonance Imaging) in depressed subjects. Read Less

This study will be comprised of 2 parts, Part A and Part B, both in healthy male participants. Part A of the study will investigate the safety of intravenous (IV) ketamine administration after single oral doses of LY2979165 (capsules) or LY2140023 (tablets). Part A will be completed before starting Part B. Part B of this study will investigate whether different dose levels of LY2979165 or LY2140023, when administered before ketamine, result in changes to the images on a brain scan seen with ketamine alone. Brain imaging is currently used for a number of reasons including understanding where in the brain medicines have their effects. Ketamine is an anesthetic used in this study to activate particular regions of the brain. The single oral doses of LY2979165 to be used in both parts of the study are 20 and 60 mg with matching dummy drug (placebo) for each dose. The doses for LY2140023 are 10, 40, and 160 mg with matching placebo for each dose. Screening is required within 28 days prior to the start of the study and follow up 7-14 days after the last dose of study drug. The study will last up to 8-weeks for an individual participant.

A cough lasting more than 2 months is known as a chronic cough, affecting 12-23% of the adult non-smoking population. Chronic cough has many associated complications including incontinence, muscular chest pains, blackouts and depression. Current treatment is often ineffective in these patients. To develop new medications the investigators need to understand more about the mechanisms that can lead to excessive coughing. This study plans to compare a group of 12 healthy volunteers and 12 patients with a chronic cough. The investigators hypothesise that that chronic cough patients have a more sensitive cough reflex as a result central nervous system hyper-excitability (central sensitisation). The investigators will measure cough reflex sensitivity before and after administration of ketamine, a medication that blocks an important receptor in the central nervous system. Read Less

RATIONALE: Ketamine hydrochloride may lessen neuropathic pain in patients with cancer. It is not yet known whether ketamine hydrochloride given together with the best pain management is more effective than a placebo given together with the best pain management in treating neuropathic pain in patients with cancer. PURPOSE: This randomized phase III trial is studying ketamine hydrochloride given together with the best pain management to see how well it works compared with giving a placebo together with the best pain management in treating cancer patients with neuropathic pain.
