Intravenous gemcitabine infused over 30 minutes weekly for 7 weeks followed by one week of rest from treatment. Subsequent cycles will consist of 1000 mg/m2 intravenous infusion over 30 minutes on days 1, 8, and 15 followed by 1 week of rest from treatment for each 28-day treatment period.

administered orally starting on day 1 followed by a continuous daily dosing of 2.0 mg

CR is defined as the disappearance of all target and non-target lesions. Any pathological lymph nodes must be <10 mm in the short axis. PR is defined as 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). CR and PR were evaluated by the Investigator using standard criteria (RECIST version 1.1). Confirmation of response was not required.

Duration of response is defined, for the subset of participants with a CR or PR, as the time from the first documented evidence of CR or PR until the first documented disease progression or death due to any cause. CR is defined as the disappearance of all target and non-target lesions. Any pathological lymph nodes must be <10 mm in the short axis. PR is defined as 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). PD is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as a reference, the smallest sum of diameters recorded since the treatment started (e.g., percent change from nadir, where nadir is defined as the smallest sum of diameters recorded since treatment start).

An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered to be related to the medicinal product. An SAE is defined as 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 results in a congenital anomaly/birth defect, or is an event of possible drug-induced liver injury. Per protocol other events were considered SAEs like symptomatic left ventricular ejection fraction (LVEF) decreases or cases of central serous retinopathy (CSR) or retinal vein occlusion (RVO). AE and SAE data were collected from the start of the first dose of study treatment and continued until 28 days following discontinuation of the study treatment or death. Refer to the general AE/SAE module for a complete list of AEs and SAEs.

A grading (severity) scale is provided for each laboratory toxicity. Grade refers to the severity of the toxicity. The Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 displays Grades 1 through 5 based on the general guideline: Grade 1, mild toxicity; Grade 2, moderate toxicity; Grade 3, severe toxicity; Grade 4, life-threatening or disabling toxicity; Grade 5, death related to toxicity.

A grading (severity) scale is provided for each laboratory toxicity. Grade refers to the severity of the toxicity. The CTCAE version 3.0 displays Grades 1 through 5, with unique clinical descriptions of the severity for each toxicity based on the general guideline: Grade 1, mild toxicity; Grade 2, moderate toxicity; Grade 3, severe toxicity; Grade 4, life-threatening or disabling toxicity; Grade 5, death related to toxicity.

Participants received placebo orally once daily in combination with 1000 mg/m^2 of gemcitabine given as IV infusion over 30 min. In the first cycle, gemcitabine was infused weekly for 7 weeks followed by a week of rest from treatment and then subsequent cycles on Day 1, 8, and 15 followed by 1 week of rest from treatment for each 28-day treatment cycle until PD, unacceptable toxicity, or permanent discontinuation from study treatment for any reason.

In the first cycle, gemcitabine was infused weekly for 7 weeks followed by a week of rest from treatment and then subsequent cycles on Day 1, 8, and 15 followed by 1 week of rest from treatment for each 28-day treatment cycle until PD, unacceptable toxicity, or permanent discontinuation from study treatment for any reason.

PFS is defined as the time from randomization until the earliest date of radiological PD or death due to any cause. PD was based on radiographic or photographic evidence, and assessments were made by the investigator according to Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1. PD is defined as at least a 20% increase in the sum of the diameters of target lesions, taking as a reference, the smallest sum of diameters recorded since the treatment started (e.g., percent change from nadir, where nadir is defined as the smallest sum of diameters recorded since treatment start). In addition, the sum must have an absolute increase from nadir of 5 millimeters (mm). PD was also based on unequivocal progression of existing non-target lesions. If the participant received subsequent anti-cancer therapy prior to the date of documented progression or death, or did not have a documented date of progression or death, PFS was censored at the last adequate assessment.

ITT Population

CR is defined as the disappearance of all target and non-target lesions. Any pathological lymph nodes must be <10 mm in the short axis. PR is defined as 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). CR and PR were evaluated by the Investigator using standard criteria (RECIST version 1.1). Confirmation of response was not required.

Measurable Disease (MD) Population: all randomized participants regardless of whether or not treatment was administered who had measurable disease at baseline

MD Population. Duration of response was assessed for only those participants with a CR or PR.

An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant, temporally associated with the use of a medicinal product, whether or not considered to be related to the medicinal product. An SAE is defined as 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 results in a congenital anomaly/birth defect, or is an event of possible drug-induced liver injury. Per protocol other events were considered SAEs like symptomatic left ventricular ejection fraction (LVEF) decreases or cases of central serous retinopathy (CSR) or retinal vein occlusion (RVO).

Safety Population: all participants who were randomized and took at least one dose of study medication. This population was based on the actual treatment received, if it differed from that to which the participant was randomized.

The Common Terminology Criteria for Adverse Events (CTCAE) version 4.0 displays Grades 1 through 5 based on the general guideline: Grade 1, mild toxicity; Grade 2, moderate toxicity; Grade 3, severe toxicity; Grade 4, life-threatening or disabling toxicity; Grade 5, death related to toxicity.

Safety Population. Only those par. with laboratory values for worst-case on therapy were analyzed. The same par. were not necessarily analyzed for each laboratory parameter; thus, the number of par. analyzed reflects all par. in the Safety Population. The number of par. analyzed for a particular parameter is included in the parameter title.
