A Study of GW856553X For the Treatment of Depression
2017年7月14日 更新者：GlaxoSmithKline
A Randomized, Double Blind, Placebo Controlled Study to Explore the Antidepressant Properties of P38a Kinase Inhibitor GW856553X 15mg Compared to PBO in Subjects With Major Depressive Disorder Exhibiting Symptoms of Loss of Energy and Interest and Psychomotor Retardation, for a Six Week Treatment Period
GW856553 is a novel compound, currently in development for the treatment of Major Depressive Disorder (MDD), and other indications.
GW856553 inhibits a protein which is responsible for the production of some pro-inflammatory molecules, called cytokines.
Increased blood levels of these molecules were seen in populations of MDD patients and this was more apparent in subjects with severe symptoms, psychomotor retardation and loss of energy.
Aim of the present study is to assess whether GW856553, by inactivating this protein, is able to suppress the production of the cytokines, and ultimately relieving depression symptoms.
In this study GW856553 or placebo is given to MDD patients 7.5md twice daily for 6 weeks.

Four different VAS (0-100 millimeter, minimum-maximum) for Sleepiness and Fatigue/Tiredness was scored before cytokine sampling at pre-dose, 2 h and 4 h post-dose.
VAS score for Sleepiness and Fatigue/Tiredness consist of following: item 1: alert (0=alert, 100=drowsy); item 2: sleepy (0=sleepy, 100=awake); item 3: strong (0=strong, 100=feeble); item 4: most tired ever felt (0=most tired ever felt, 100=less tired ever felt).
Fatigue/Tiredness was based on score of item 3 and 4 and sleepiness on score of item 1 and 2. All item scores do not move in same direction.
Score for item 1 and 3 ranged from 0-100, where 0=absence of symptom and higher score=greater severity of symptom.
Score for item 2 and 4 ranged from 0-100, where 0=most severe symptom and higher score=less severe symptom.
Randomization value defined as assessment done on Day 1 (Week 0, pre-dose).
Change from Randomization was calculated by subtracting Randomization value from individual post-Randomization (Week 0-6) values.

Maximum plasma concentration (Cmax) of GW856553X and GSK198602
時間枠：Pre-dose and 4 h post-dose at Week 2 and Week 6
|
Plasma concentration of GW856553X and of the metabolite GSK198602 was assessed during the treatment period.
Blood samples were collected at 8:00 h (before dosing) and 12:00-13:00 h (about 4 h after dosing) at Weeks 2 and 6 of the treatment period.
The first occurrence of the maximum observed plasma concentration was planned to be determined directly from the raw concentration-time data.
The data for this outcome measure was not derived due to early termination.

Median time to Cmax (tmax) and the terminal phase half-life (t1/2)
時間枠：Pre-dose and 4 h post-dose at Week 2 and Week 6
|
Plasma concentration of GW856553X and of the metabolite GSK198602 was assessed during the treatment period.
Blood samples were collected at 8:00 h (before dosing) and 12:00-13:00 h (about 4 h after dosing) at Weeks 2 and 6 of the treatment period.
The time at which Cmax observed was planned to be determined directly from the raw concentration-time data.
The apparent t1/2 was planned to be obtained as the ratio of ln2/λz, where λz is the terminal phase rate constant estimated by linear regression analysis of the log transformed concentration-time data.
The data for this outcome measure was not derived due to early termination.

The area under the plasma concentration-time curve (AUC)
時間枠：Pre-dose and 4 h post-dose at Week 2 and Week 6
|
Blood samples were collected at 8:00 h (before dosing) and 12:00-13:00 h (about 4 h after dosing) at Weeks 2 and 6 of the treatment period.
The AUC was planned to be assessed from time zero (pre-dose) extrapolated to infinite time (AUC0-infinity) and from time zero (pre-dose) to last time of quantifiable concentration within a participant across all treatments (AUC0-t).
AUC0-t was planned to be determined using the linear trapezoidal rule for increasing concentrations and the logarithmic trapezoidal rule for decreasing concentrations.
The AUC0-infinity was planned to be calculated, where data permitted, as the sum of AUC0-t and Ct/z, where Ct is the observed plasma concentration obtained from the log-linear regression analysis of the last quantifiable time-point and z is the terminal phase rate constant.
The data for this outcome measure was not derived due to early termination.
