Eltrombopag olamine

AEs are coded using the standard Medical Dictionary for Regulatory Activities (MedDRA) and were graded by the investigator according to National Cancer Institute (NCI) Common Terminology Criteria for AEs (CTCAE), version 4.0. AE is any untoward medical occurrence temporally associated with the use of a medicinal product (MP), whether or not considered related to the MP. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease (new or exacerbated) temporally associated with the use of a MP. For marketed MPs, this also includes failure to produce expected benefits, abuse, or misuse. SAE event is any untoward medical occurrence that, at any dose: results in death, is life-threatening, requires hospitalization or prolongation of existing hospitalization, results in disability/incapacity, or, is a congenital anomaly/birth defect.

Hematology parameters with a related NCI CTCAE (version 4.0) toxicity grading were summarized by toxicity grade at each scheduled assessment, the maximum toxicity grade reached by a participant post-Baseline was summarized. Hematology parameters included hemoglobin (increased), hemoglobin (anemia), lymphocytes (increased), lymphocytes (decreased), total absolute neutrophil count (ANC), platelets (PLT) and white blood cells (WBC). The Baseline value is defined as the value reported immediately prior to the administration of the first dose of chemotherapy in Cycle 1. Post-Baseline is defined as any time after the first dose of chemotherapy in Cycle 1 up to and including all follow-up visits. Only those participant available at the indicated time points were analyzed (represented by n=X,X,X,X in the category titles).

Clinical chemistry laboratory parameters with a related NCI CTCAE (version 4.0) toxicity grading were summarized by toxicity grade at each scheduled assessment. Clinical chemistry laboratory parameters included albumin (Alb), urea/blood urea nitrogen (BUN), creatinine, aspartate amino transferase (AST), alanine amino transferase (ALT), alkaline phosphatase (ALP), total bilirubin (TB), direct bilirubin (DB) and international normalized ratio/Prothrombin time (PT). The Baseline value is defined as the value reported immediately prior to the administration of the first dose of chemotherapy in Cycle 1. Post-Baseline is defined as any time after the first dose of chemotherapy in Cycle 1 up to and including all follow-up visits. Only those participants available at the indicated time points were analyzed (represented by n=X,X,X,X in the category titles).

The number of participants with at least 1 change from Baseline in creatinine, with an increase \>=26.5 UMOL/L are reported. Creatinine clearance is estimated using the Cockcroft-Gault formula which is a method to approximate kidney function. The Baseline value is defined as the value reported immediately prior to the administration of the first dose of chemotherapy in Cycle 1.

ECOG-Zubrod scores for the performance status are defined as follows: Score 0: Fully active, 1: restricted in physically strenuous activity but ambulatory and able to carry out work of a light or sedentary nature, 2: ambulatory and capable of all self-care but unable to carry out any work activities, 3: capable of only limited self-care, 4: completely disabled, 5: dead. The data is presented for the participants with the ECOG performance score at the indicated time points during the study.

A single safety 12-lead ECG was performed using a standard 12-lead ECG machine at screening and post-dose on C2D4. Three further ECGs were carried out at C2D8, C5D8 and C6D15. Change in ECG findings were categorized as 'Clinically significant change: favorable', 'No change or insignificant change' or 'Clinically significant change (CSC): unfavorable' as determined by the investigator. The Baseline value is defined as the value reported immediately prior to the administration of the first dose of chemotherapy in Cycle 1. Any time post-Baseline is defined by counting the participants under the worst result experienced post-Baseline. The best to worst order is 'Clinically significant change: favorable', 'No change or insignificant change', and then 'Clinically significant change (CSC): unfavorable. Only those participants available at the indicated time points were analyzed (represented by n=X,X,X,X in the category titles).

Scheduled pre-chemotherapy platelet count is defined within each cycle as the platelet count assessment on which the decision to give or delay chemotherapy was made. This was averaged for each participant across Cycles 1 to 6 and a natural log transformation was applied to the average. The log-transformed values were compared between eltrombopag and placebo groups using an analysis of covariance (ANCOVA) model adjusting for cycle duration (21-day vs. 28-day), Baseline loge(platelet count) and part of study (part 1 or 2 of phase II). Only those participants available at indicated time points were analyzed (represented by n=X,X).
