Interventions

Primary outcome

1. Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)-Parts 1 and 2

   Time frame: Median of 6.143 weeks of drug exposure

   An AE is any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. An SAE 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; is a congenital anomaly/birth defect; important medical events that may require medical or surgical intervention to prevent one of the outcomes mentioned; events of possible study treatment-induced liver injury with hyperbilirubinemia; and left ventricular ejection fraction (LVEF) meeting stopping criteria. AEs were collected in All Treated Population which comprised of all participants who received at least one dose of GSK2849330. Treatment groups with same dose and administration frequency were combined as pre-specified in reporting and analysis plan.

2. Number of Participants With Dose-limiting Toxicities (DLTs)-Parts 1 and 2

   Time frame: Up to 28 days

   An event was considered a DLT if it occured within the first 4 weeks (28 days) of treatment, and met one of the following criteria unless it could be established that the event was unrelated to treatment: Grade 3 or greater non-hematologic toxicity; Grade 4 neutropenia lasting >5 days; Febrile neutropenia, of any grade or duration; Grade 4 thrombocytopenia, or Grade 3 thrombocytopenia associated with bleeding; Alanine aminotransferase (ALT) >3 times upper limit of normal (ULN) with bilirubin >2 times ULN; Any Grade 2 or greater toxicity that in the judgment of the investigator and GlaxoSmithKline (GSK) Medical Monitor, would be considered dose-limiting; Grade 3 or greater decrease in LVEF. Treatment groups with same dose and administration frequency were combined as pre-specified in reporting and analysis plan.

3. Number of Participants With Grade Change From Baseline in Clinical Chemistry Data-Parts 1 and 2

   Time frame: Baseline and median of 6.143 weeks of drug exposure

   Blood samples were collected for the analysis of following clinical chemistry parameters: albumin, alkaline phosphatase (ALP), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (Total bil), calcium, creatinine, gamma glutamyl transferase (GGT), glucose, potassium, magnesium, sodium, phosphorus, uric acid. Laboratory parameters were graded according to National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 4.0. Grade 1: mild; Grade 2: moderate; Grade 3: severe or medically significant; Grade 4: life-threatening consequences; Grade 5: death related to AE. Baseline is the most recent, non-missing value from a central laboratory prior to or on the first study treatment dose date. Change from Baseline was calculated as visit value minus Baseline value. Data for worst-case post Baseline is presented. Treatment groups with same dose and administration frequency were combined as pre-specified in reporting and analysis plan.

4. Number of Participants With Change From Baseline in Clinical Chemistry Data With Respect to Normal Range-Parts 1 and 2

   Time frame: Baseline and median of 6.143 weeks of drug exposure

   Blood samples were collected for the analysis of following clinical chemistry parameters: direct bilirubin (D.Bil.), cancer antigen (CA)-125, CA-15.3, CA19-9, chloride, carbon dioxide (CO2)/bicarbonate (HCO3), luteinizing hormone (LH), total protein and urea or blood urea nitrogen (BUN). Baseline was defined as the most recent, non-missing value from a central laboratory prior to or on the first study treatment dose date. Change from Baseline was calculated as visit value minus Baseline value. A laboratory value that is outside the reference range was considered either high abnormal (value above the upper limit of the reference range) or low abnormal (value below the lower limit of the reference range). Number of participants with change from Baseline in clinical chemistry data at worst-case post Baseline is presented. Treatment groups with same dose and administration frequency were combined as pre-specified in reporting and analysis plan.

5. Number of Participants With Grade Change From Baseline in Hematology Data-Parts 1 and 2

   Time frame: Baseline and median of 6.143 weeks of drug exposure

   Blood samples were collected for the analysis of following hematology parameters: hemoglobin, lymphocytes, total neutrophils, platelet count, and white blood cell (WBC). The laboratory parameters were graded according to NCI-CTCAE version 4.0. Grade 1: mild; Grade 2: moderate; Grade 3: severe or medically significant; Grade 4: life-threatening consequences; Grade 5: death related to AE. Baseline was defined as the most recent, non-missing value from a central laboratory prior to or on the first study treatment dose date. Change from Baseline was calculated as visit value minus Baseline value. Number of participants with any grade increase, increase to Grade 3 and increase to Grade 4 in hematology data at worst-case post Baseline is presented. Treatment groups with same dose and administration frequency were combined as pre-specified in reporting and analysis plan.

6. Number of Participants With Change From Baseline in Hematology Data With Respect to Normal Range-Parts 1 and 2

   Time frame: Baseline and median of 6.143 weeks of drug exposure

   Blood samples were collected for the analysis of following hematology parameters: basophils, eosinophils, hematocrit, mean corpuscle hemoglobin concentration (MCHC), mean corpuscle hemoglobin (MCH), mean corpuscle volume (MCV), monocytes, red blood cell count (RBC) and reticulocytes. A laboratory value that was outside the reference range was considered either high abnormal (value above the upper limit of the reference range) or low abnormal (value below the lower limit of the reference range). Baseline was defined as the most recent, non-missing value from a central laboratory prior to or on the first study treatment dose date. Change from Baseline was calculated as value at visit minus Baseline value. Number of participants with change from Baseline in hematology data at worst-case post Baseline is presented. Treatment groups with same dose and administration frequency were combined as pre-specified in reporting and analysis plan.

7. Number of Participants With Change From Baseline in Urinalysis Data With Respect to Normal Range-Parts 1 and 2

   Time frame: Baseline and median of 6.143 weeks of drug exposure

   Urine samples were collected for the analysis of urine potential of hydrogen (pH) and urine specific gravity. A laboratory value that was outside the reference range was considered either high abnormal (value above the upper limit of the reference range) or low abnormal (value below the lower limit of the reference range). Baseline was defined as the most recent, non-missing value from a central laboratory prior to or on the first study treatment dose date. Change from Baseline was calculated as visit value minus Baseline value. The data for worst-case post Baseline is presented. Treatment groups with same dose and administration frequency were combined as pre-specified in reporting and analysis plan.

8. Number of Participants With Change From Baseline in Vital Signs-Parts 1 and 2

   Time frame: Baseline and median of 6.143 weeks of drug exposure

   Vital sign measurements included systolic blood pressure (SBP), diastolic blood pressure (DBP), temperature (Temp) and heart rate (HR). Vital signs were graded according to NCI-CTCAE version 4.0. The following criteria was used to flag vital signs of potential clinical importance: change from Baseline in HR (decrease to <60 beats per minute and increase to >100 beats per minute); increase in SBP from Baseline (>=120 to <140 millimeters of mercury [mmHg] Grade 1; >=140 to <160 mmHg [Grade 2]; >=160 [Grade 3]); increase in DBP from Baseline (>=80 to <90 [Grade 1]; >=90 to <100 [Grade 2]; >=100 mmHg [Grade 3]) and change in temperature from Baseline (increase to >=38 or decrease to <=35 degree Centigrade). Baseline was defined as the most recent, non-missing value prior to or on the first study treatment dose date. Change from Baseline was calculated as visit value minus Baseline value. The data for worst-case post Baseline is presented.

9. Number of Participants With Abnormal Electrocardiogram (ECG) Findings-Parts 1 and 2

   Time frame: Median of 6.143 weeks of drug exposure

   A 12-lead ECG was measured using an automated ECG machine after at least 5 minutes of rest for the participant in a semi-recumbent or supine position. Number of participants with abnormal ECG findings at any time post-Baseline is presented. Treatment groups with same dose and administration frequency were combined as pre-specified in reporting and analysis plan.
