Trial overview

Official title: A 4-part parallel group, randomized, study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamic effects of repeat doses of GSK1018921 in healthy volunteers and stable patients with schizophrenia and to evaluate its effects on pharmacokinetics of midazolam.
Trial description: The purpose of this study is to understand safety and tolerability of the drug GSK1018921 after 14 days of dosing in healthy volunteers and then in patient volunteers.
Primary purpose:
Treatment

Double (Participant, Investigator)
Allocation:
Randomized
Primary outcomes:

Part A: Safety and tolerability endpoints consisting of: adverse events; 12-lead ECG; vital signs, clinical laboratory evaluations and PK parameters.

Timeframe: 14 days twice daily dosing.

Part B: Midazolam PK following single and repeat doses of GSK1018921.

Timeframe: 14 days twice daily dosing.

Part C: Plasma & CSF glycine concentrations following single doses og GSK1018921.

Timeframe: After single dosing.

Part D: Safety and tolerability endpoints consisting of: adverse events; 12-lead ECG; vital signs, clinical laboratory evaluations and movement scales Simpson Angus Scale, AIMS and Barnes akathisia Scale.

Timeframe: 28 days

Secondary outcomes:

Part A: Effects of GSK1018921 on VAS

Timeframe: 14 days.

Part B: None

Timeframe: 0

Part C: GSK1018921 plasma exposure-CSF glycine relationship
