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.
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.
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.
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.
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.
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.
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.
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.
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.

GSK2849330 is an investigational small molecule being studied for the treatment of cancer, specifically advanced solid tumors that are positive for HER3 (human epidermal growth factor receptor 3). It has been evaluated in Phase 1 clinical trials in patients with HER3-positive solid tumors and other neoplasms.
GSK2849330 is being developed by GSK plc, which trades under the ticker GSK. The company sponsored both Phase 1 trials of the drug.
GSK2849330 is in Phase 1 clinical development. Both of its trials were Phase 1 studies, and both have been completed. It is an investigational agent and has not been approved by the FDA.
GSK2849330 has been studied in two completed Phase 1 trials: NCT02345174, an immuno-positron emission tomography study in HER3-positive solid tumors conducted in the Netherlands, and NCT01966445, a dose escalation study in advanced HER3-positive solid tumors conducted in the United States, Australia, and the Netherlands.
Across the two completed Phase 1 trials, a total of 35 patients were enrolled. NCT01966445 enrolled 29 patients, and NCT02345174 enrolled 6 patients. Both studies required participants to be at least 18 years old and included both sexes.
