Cohort 1EXPERIMENTALSubjects in Cohort 1 will be randomized to one of the following sequences: ABDFH, BADFH, BDAFH, BDFAH and BDFHA in a 1:1:1:1:1 ratio where A = Placebo, B= GSK618334 dose 1 (2.5 mg), D = GSK618334 dose 3, F = GSK618334 dose 5, H = GSK618334 dose 7. On day 1, subjects will be administered a starting dose of 2.5 milligrams (mg) GSK618334. The planned doses of GSK618334 to be administered in Cohort 1 are 2.5, 25, 100 and 400mg. In each dosing period 2 subjects will receive placebo and 8 subjects will receive GSK618334. Subjects within a cohort will have a washout period of at least two weeks from last dose before receiving another dose.

In each dosing period 2 subjects will receive placebo and 8 subjects will receive GSK618334. Subjects within a cohort will have a washout period of at least two weeks from last dose before receiving another dose.

Frequently asked questions about GSK618334

What is GSK618334 used for?

GSK618334 is being studied for substance dependence, a psychiatric condition. It is a small molecule developed by GSK plc and has been tested in Phase 1 clinical trials conducted in the United Kingdom. All three of its recorded trials enrolled healthy volunteers rather than patients in treatment.

Who makes GSK618334?

GSK618334 is developed by GSK plc, which trades under the ticker GSK. The company sponsored all three Phase 1 trials of the compound, which were run in the United Kingdom. GSK618334 is also referred to as GSK618334 Low Dose.

What phase is GSK618334 in?

GSK618334 is in Phase 1 clinical development. All three of its registered trials are Phase 1 studies, and all three are listed as completed. There are no active trials of GSK618334 at this time, and the compound is investigational rather than approved.

What clinical trials is GSK618334 in?

GSK618334 has been studied in three completed Phase 1 trials: NCT01036061, a repeat dose study with 46 participants; NCT00814957, an open label PET study using 11C-PHNO as ligand with 12 healthy male subjects; and NCT00513279, a single dose safety and blood level study with 20 male participants. All were run in the United Kingdom.

Is GSK618334 the same as GSK618334 Low Dose?

Yes, GSK618334 Low Dose is an alternative name for GSK618334. Both names refer to the same small molecule developed by GSK plc for substance dependence. Searches using either name point to the same Phase 1 program, which includes three completed trials in the United Kingdom.

How many people were enrolled in GSK618334 trials?

The three completed Phase 1 trials of GSK618334 enrolled a total of 78 participants. NCT01036061 enrolled 46, NCT00513279 enrolled 20, and NCT00814957 enrolled 12. The studies were randomized, double blind, and controlled, and they enrolled healthy volunteers rather than patients.
