Outcomes

Primary Outcomes

Number of Participants With Objective Response Rate (ORR), of GSK1363089, Per- Response Evaluation Criteria in Solid Tumors (RECIST) Criteria Version 1.0

ORR is defined as the percentage of participants achieving best overall response of confirmed complete response (CR) or partial response (PR). Tumor response for participants with measurable lesions was assessed routinely (after 8 weeks of treatment and approximately every 8 weeks thereafter) using RECIST (version 1.0) criteria. The CR for target lesions was defined as disappearance of all target lesions (TLs) and the non-target lesions (NTLs). PR defined as at least 30% decrease in sum of the longest diameter (LD) of TLs, taking as reference baseline sum LD. The safety population included all participants who passed the screening criteria, enrolled in the study, and received at least 1 dose of study drug. Progressive disease will be used as PD.

Time frame: At every 8 Weeks upto 31 months

Number of Participants With Adverse Event (AE) and Serious Adverse Event (SAE)

An AE is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product whether or not it is considered drug related. This would include any side effect, injury, toxicity, sensitivity reaction, abnormal or worsening of a laboratory value, concurrent illness or sudden death. Pre-existing conditions that worsen during a study will be reported as AEs. SAE is an AE that results in death, is life-threatening, requires inpatient hospitalization or extends a current hospital stay, results in an ongoing or significant incapacity or interferes substantially with normal life functions, or causes a congenital anomaly or birth defect. Medical events that do not result in death, are not life-threatening, or do not require hospitalization may be considered SAEs if they put the participant in danger or require medical or surgical intervention to prevent one of the results listed above.

Time frame: Up to 31 months

Change From Baseline in Vital Signs-Systolic and Diastolic Blood Pressure

Participants systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured in mm of mercury (mmHg). These were collected after the participant sat quietly for at least five minutes. The change from baseline was calculated by subtracting the baseline values from the individual post-randomization values. The data for minimum (min) and maximum (max) post-baseline has been reported. Baseline is defined as the last non-missing record on or before first dose.

Time frame: Baseline (pre-dose, Day 1) and before 30-day follow- up (up to 2 years)

Change From Baseline in Vital Signs-Pulse Rate

The pulse rate or heart rate (HR) for the participant's, were collected after the participant sat quietly for at least five minutes. Baseline evaluations were performed within 72 hours before the first dose. If performed within 24 hours of the first dose, baseline evaluations may serve as the pre-dose Day 1 visit evaluations. The change from baseline was calculated by subtracting the baseline values from the individual post-randomization values. Baseline was defined as pre-dose, Day 1. The HR was measured in beats per minute (bpm). The min and max values have been reported.

Time frame: Baseline (pre-dose, Day 1) and before 30-day follow- up (up to 2 years)

Change From Baseline in Temperature

The body temperature for the participants was assessed. These were collected after the participant sat quietly for at least five minutes. The change from baseline was calculated by subtracting the baseline values from the individual post-randomization values. Baseline is defined as the last non-missing record on or before first dose.

Time frame: Baseline (pre-dose, Day 1) and before 30-day follow- up (up to 2 years)

Change From Baseline in Respiratory Rate (RR)

The RR for the participant's, were collected after the participant sat quietly for at least five minutes. Baseline evaluations should be performed within 72 hours before the first dose. If performed within 24 hours of the first dose, baseline evaluations may serve as the pre-dose Day 1 visit evaluations. The change from Baseline was calculated by subtracting the Baseline values from the individual post-randomization values. Baseline was defined as pre-dose, Day 1 . The RR was measured in breaths per minute. Min and max post-baseline values are reported.

Secondary Outcomes

Median Progression Free Survival (PFS) of GSK1363089

Duration of PFS in months is defined as (Date of Disease Progression/Death - Date of First Dose + 1)/30.44. For participants who did not reach an event (disease progression or death) at the time of data cut-off, duration of PFS is censored at date of last available tumor assessment that is not 'Unable to Evaluate'. For participants who did not have any post-baseline tumor assessments, PFS was censored at Day 1. For any participants who received subsequent anti-cancer therapy, PFS will be right censored at the date of last adequate tumor assessment on or prior to the date of anti-cancer therapy initiation. For any participants who died or progressed after an extended lost-to-follow-up time (greater than 17 weeks), PFS was censored at the date of last adequate assessment prior to extended lost-to follow-up.

Time frame: At every 8 Weeks upto 31 months

Duration of Stable Disease of GSK1363089

Duration of stable disease, was defined as the time between the date of first dose and death or disease progression, in participants whose best overall response was not progressive disease

Time frame: At every 8 Weeks upto 31 months

Disease Stabilization Rate of GSK 1363089

It is defined as the number of participants achieving best overall response of confirmed CR or PR or stable disease (SD). It was assessed using RECIST criteria 1.0. The CR for target lesions was defined as disappearance of all TLs and the NTLs. PR is at least 30% decrease in sum of the LD of TLs, taking as reference baseline sum LD. SD was defined as neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as a reference, the smallest sum LD since the treatment started.

Time frame: At every 8 Weeks upto 31 months

Median Duration of Overall Survival (OS)of GSK1363089

Duration of OS is defined as (Date of Death \[due to any cause\]) minus Date of first dose. For the participants who were alive at the time of data cut-off, duration of overall survival was censored at the date of last contact. The upper value of the full range was censored observation.

Time frame: At every 8 Weeks upto 31 months
