Participants received 25 milligrams (mg) of LY3039478, administered orally three times per week (TIW) in a 28-day cycle, until disease progression, development of unacceptable toxicity, or any other discontinuation criteria were met.

Participants received 50 mg of LY3039478, administered orally TIW in a 28-day cycle, until disease progression, development of unacceptable toxicity, or any other discontinuation criteria were met.

Administered orally

DLT was defined as an adverse event (AE) that occurred during Cycle 1 (first 28 days) related to the study drug and met one of the following criteria per the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) v4.0. These criteria included: CTCAE Grade greater than or equal to (≥) 3 non-hematological toxicity, with exceptions for nausea, vomiting, or constipation, and asymptomatic electrolyte disturbances that can be controlled with standard treatment; Grade 4 hematological toxicity of greater than (>) 5 days duration; Grade ≥ 3 anemia requiring transfusion; any febrile neutropenia; neutropenia needing granulocyte-colony stimulating factors (GCSFs); Grade 3 thrombocytopenia with bleeding or requiring platelet transfusion; Grade 4 thrombocytopenia.

• The ORR was defined as the percentage of participants achieving either a CR or PR. Tumor response was assessed based on histology: Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) was used for solid tumors, and Response Assessment in Neuro-Oncology criteria were used for glioblastoma.
• CR was defined as the disappearance of all target lesions, with any pathological lymph nodes (whether target or non-target) showing a reduction in the short axis to <10 mm. Additionally, tumor marker results were required to have normalized. PR was defined as a decrease of at least 30% in the sum of the diameters of target lesions, using baseline diameters as the reference.

All participants with evaluable DLT data in Cycle 1 (the first 28 days) had received greater than or equal to (≥) 75% of the assigned dose during Cycle 1 or had experienced a DLT during Cycle 1.
