Assessment method [1]
0
0
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.

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.

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.

Overall Response Rate (ORR)-Parts 1 and 2

ORR was determined by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST v 1.1). ORR was calculated as the number of participants with best overall response of complete response (CR) and partial response (PR). CR=Disappearance of all target lesions. Any pathological lymph nodes must be <10 millimeter (mm) in the short axis and PR=At least a 30% decrease in the sum of the diameters of target lesions, taking as a reference, the Baseline sum of the diameters (e.g., percent change from Baseline). An estimate to the true response rate for the number of participants analyzed is given. The 95% confidence interval was the exact confidence interval based on binomial proportion for ORR. Treatment groups with same dose and administration frequency were combined as pre-specified in reporting and analysis plan.

Serum samples were collected for the determination of anti-GSK2849330 antibodies using a validated immunoelectrochemiluminescent (ECL) assay. The assay involved screening, confirmation and titration steps (tiered-testing approach). If serum samples contained anti-GSK2849330 antibodies, they were further analyzed for the specificity of antibodies by a confirmation assay. Confirmed positive samples were titrated to obtain the titers of antibodies. The number of participants who tested positive for anti-GSK2849330 antibody in confirmatory testing on Day 1 and 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.

Summary
Brief summary
Human Epidermal Growth Factor Receptor 3 (HER3) expression is seen across a wide variety of
solid malignancies and is associated with poor prognosis. Up-regulation of HER3 expression
and activity is also associated with resistance to multiple pathway inhibitors. GSK2849330, a
monoclonal antibody targeting HER3, is a new agent for subjects whose tumors express HER3.
This study is a phase I, first time in human, open-label, dose escalation study. The purpose
of this study is to investigate the safety, pharmacokinetics (PK), and pharmacodynamics (PD)
of GSK2849330 in subjects with advanced HER3-positive solid tumors. The study will be
conducted in two parts. Part 1 (Dose-Escalation Phase) will include dose escalation and PK/PD
cohorts to evaluate safety, PK, and PD to guide selection of dose regimen(s) for Part 2. In
Part 2 (Expansion Cohorts), up to 3 cohorts will be enrolled at the dose regimen(s) selected
based on Part 1 data, to evaluate safety in a larger cohort of subjects at the recommended
dose regimen and also to evaluate preliminary evidence of clinical benefit.
