Grade 3 fever (in the absence of neutropenia) defined as more than (\>) 40.0 degree Celcius (\> 104.0 degree Fahrenheit) that resolved to normal or baseline within 24 hours of treatment and was not considered a serious adverse event (SAE); or 2. Grade 3 rigors/chills that responded to optimal therapy. 2. Any treatment-related Grade 3 or higher hematologic toxicity.

PRIMARY outcome

Timeframe: From Day 1 to Day 21 of first cycle

Population: The evaluable population for dose determination included all participants who were in Phase 1b, received at least 1 full cycle of MEDI-575 and completed the safety follow-up through the DLT evaluation period or participants who experienced any DLT.

A DLT was defined as: 1. Any treatment-related Grade 3 or higher non-hematologic toxicity that occurred during the DLT assessment period with the following exceptions: 1. Grade 3 fever (in the absence of neutropenia) defined as more than (\>) 40.0 degree Celcius (\> 104.0 degree Fahrenheit) that resolved to normal or baseline within 24 hours of treatment and was not considered a serious adverse event (SAE); or 2. Grade 3 rigors/chills that responded to optimal therapy. 2. Any treatment-related Grade 3 or higher hematologic toxicity.

0 Participants

PRIMARY outcome

Timeframe: From randomization until the end of study (14 months from last participant enrolled or sponsor stopped the study), assessed at every 6 weeks until disease progression and every 3 months until the end of the study (approximately 3 years)

Population: The Intent-to-Treat (ITT) North America/EU population included all North America/EU participants who were randomized into Phase 2 portion of the study. The PFS was analyzed for only those participants who had disease progression.

Progression-free survival defined as the time from randomization (randomization referred to the date of treatment assignment) to disease progression (defined according to Response Evaluation Criteria for Solid Tumors \[RECIST\] version 1.1 guidelines) or death due to any cause, whichever occurs first. Participants without progression or death at the time of analysis were censored at their last date of tumor evaluation. PFS was assessed only in North America/European Union (EU) participants. Progression-free survival was evaluated using Kaplan-Meier method.

SECONDARY outcome

Timeframe: From initiation of treatment until the end of study (14 months from last participant enrolled or sponsor stopped the study), assessed at every 6 weeks until disease progression and every 3 months until the end of the study (approximately 3 years)

Population: The ITT North America/European Union (EU) population included all North America/EU participants who were randomized into Phase 2 portion of the study. The ITT Japanese population included all Japanese participants who were randomized into the Phase 2 portion of the study.

Best overall response of a participant was defined as the best tumor response \[Complete Response (CR), Partial Response (PR), Stable Disease (SD), or Progressive Disease (PD)\] observed during the trial period assessed according to the Response Evaluation Criteria for Solid Tumors (RECIST) version 1.1 criteria. The participant's best overall response assignment depended on the findings of both target and non-target disease and also on the appearance of new lesions. CR was defined as disappearance of tumor lesions, PR was defined as a decrease of at least 30 percent (%) in the sum of diameters of target lesion, SD was defined as steady state of disease, and PD was defined as an increase of at least 20% in the sum of diameters of target lesions.

The 95% confidence interval was not determined as only 1 participant was analyzed.

SECONDARY outcome

Timeframe: From initiation of treatment until the end of study (14 months from last participant enrolled or sponsor stopped the study), assessed at every 6 weeks until disease progression and every 3 months until the end of the study (approximately 3 years)

Population: The ITT North America/EU population included all North America/EU participants who were randomized into Phase 2 portion of the study. The ITT Japanese population included all Japanese participants who were randomized into the Phase 2 portion of the study. Participants who achieved OR were analyzed for this outcome measure.

The DR defined as the duration from the first documentation of OR to the first documented disease progression. Participants without progression at the time of analysis were censored at their last date of tumor evaluation. The DR was evaluated using Kaplan-Meier method.

Population: The ITT North America/EU population included all North America/EU participants who were randomized into Phase 2 portion of the study. The ITT Japanese population included all Japanese participants who were randomized into the Phase 2 portion of the study. The TTP was analyzed for only those participants who had disease progression.

The TTP was measured from randomization until the documentation of disease progression. Disease progression defined according to RECIST version 1.1 guidelines. Participants without progression at the time of analysis were censored at their last date of tumor evaluation. The TTP was evaluated using Kaplan-Meier method.

SECONDARY outcome

Timeframe: Baseline (Screening [Days -28 to -1])

Population: Evaluable populations for PDGFRα expression included all randomized participants who had formalin-fixed paraffin-embedded samples available at baseline and had positive-staining for tumor cells.

The immunohistochemical expression of PDGFRα in tumor cells in archived formalin-fixed paraffin-embedded tissue samples collected at baseline are reported. The transmembrane receptor tyrosine kinase PDGFRα plays an important role in human carcinogenesis, both as a direct target on tumor cells and also as a mediator of stromal support for cancer cell growth. The data of positive-staining tumor cells are reported in 3 categories: intensity (1+ \[weak expression, staining in \<5 % of tumor cells\]; 2+ \[moderate expression, staining in \>= 5 % of tumor cells\]; and 3+ \[strong expression, staining in \>5 % of the tumor cells\]), localization (membranous, cytoplasmic, or nuclear), and frequency (rare, occasional, or frequent).
