Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Maximum Tolerated Dose (MTD) of TAK-117	MTD is highest dose level of TAK-117 at which no more than 1 out of 6 participants had a dose limiting toxicity (DLT) during first cycle. DLT was any 1 of following events occurring within first 21 days of Cycle 1 of TAK-117 administration, Grade 2: fasting hyperglycemia for >14 days. Grade 3: nausea and/or vomiting/diarrhea for >7 days; rash for >7 days; thrombocytopenia with bleeding; fasting hyperglycemia for >24 hours(hr). Grade >=3:nonhematologic toxicity considered clinically significant by investigator. Grade 4:neutropenia (absolute neutrophil count <=0.5*10^9per liter[/L]) for >7 days in absence of growth factor support; neutropenia of any duration accompanied with fever >=38.5 degree Celsius and/or systemic infection. Grade >=4:hematologic toxicity. Inability to administer at least 75% of planned doses of TAK-117 within Cycle 1 due to its related toxicity;Any clinically significant occurrence that investigators and sponsor agreed would place participants at undue safety risk.	Baseline up to Cycle 1 Day 21
Number of Participants Reporting One or More Treatment-emergent Adverse Events (TEAEs), Serious Adverse Events (SAEs), Death, Adverse Events (AEs) Leading to Discontinuation of Study Drug, and DLTs in Cycle 1		Baseline up to Cycle 27 Day 45
Number of Participants With Highest Level of TEAEs Severity	Severity of AEs was evaluated based on National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE), version 4.0 as follow: Grade 1 (mild); Grade 2 (moderate); Grade 3 (severe); Grade 4 (life-threatening); Grade 5 (fatal).	Baseline up to Cycle 27 Day 45
Number of Participants With Clinically Meaningful Changes in Laboratory Values		Baseline up to Cycle 27 Day 45
Number of Participants With Clinically Meaningful Changes in Vital Signs		Baseline up to Cycle 27 day 45
Number of Participants With Clinically Meaningful Changes in Electrocardiogram (ECG)		Baseline up to Cycle 27 Day 45

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Overall Response Rate (ORR)	The estimate of the ORR is calculated as crude percentage of participants who's best overall response is complete response (CR) or partial response (PR). Objective response (CR and PR) as determined by the participants best tumor response was assessed using response evaluation criteria in solid tumors (RECIST) version 1.1. As per RECIST version 1.1, CR was defined as complete disappearance of all target lesions and non-target disease, with the exception of nodal disease. All nodes, both target and non-target, must decrease to normal (short axis <10 millimeter [mm]). No new lesions. PR was defined as >=30% decrease under baseline of the sum of diameters of all target lesions. The short axis was used in the sum for target nodes, while the longest diameter was used in the sum for all other target lesions. No unequivocal progression of non-target disease. No new lesions. Stable disease was defined as not qualifying for CR, PR, and progressive disease (PD).	Cycle 1 Day 8 up to Cycle 27 Day 1 or disease progression or death
Duration of Objective Response	Duration of response was to be calculated for participants who achieved CR or PR. Duration of objective response was defined as the number of days from the start date of PR or CR (whichever response was achieved first) to the first date that PD or disease progression was objectively documented. The duration of objective response was to be right-censored for participants who achieved CR or PR and met 1 of the following conditions: Non-protocol anticancer treatment started before documentation of PD; Documented PD after more than 1 missed disease assessment visit; Alive and did not have documentation of PD before a data analysis cutoff date.	Cycle 1 Day 8 up to Cycle 27 Day 1 or disease progression or death
Clinical Benefit Rate (CBR)	Clinical benefit rate was defined as the participants who achieved stable disease (SD) for at least 15 weeks, CR, or PR. The estimate of the CBR was calculated as crude percentage of participants whose best ORR was CR, PR or SD for at least 90 days.	Cycle 1 Day 8 up to Cycle 27 Day 1 or disease progression or death
