A Study to Evaluate Safety, Efficacy, and Pharmacokinetics in Participants With Advanced Solid Tumors

Inclusion Criteria

• •Histologically or cytologically confirmed diagnosis of metastatic or locally advanced solid tumors for which no standard therapy exists or standard therapy has failed because of disease progression or unacceptable toxicities. Also includes patients who cannot be treated with standard therapy because of underlying/existing medical condition.
• •Cohort 1 (colorectal cancer): a) CRC (including microsatellite instability-high \[MSI-H\] and microsatellite-stable \[MSS\]) regardless of RAS mutation. b) Disease progression within 3 months after last administration of approved standard therapies. c) Prior cytotoxic chemotherapy for metastatic disease include all the following agents: fluoropyrimidine, oxaliplatin, and irinotecan
• •Adjuvant chemotherapy-based treatments count as prior therapy, as long as relapse had occurred within 6 months of completion of such therapies, prior anti-epidermal growth factor receptor (EGFR) therapy (cetuximab, panitumumab), anti-angiogenic therapy (bevacizumab, aflibercept, ramucirumab), regorafenib, and TAS-102 are allowed. d) No more than 5 prior therapies for metastatic disease. For participants who had disease recurrence within 6 months of completing adjuvant chemotherapy, the adjuvant regimen can be considered as 1 chemotherapy regimen for metastatic disease
• •Cohort 2 (NSCLC): a) NSCLC without known EGFR, anaplastic lymphoma kinase (ALK), and ROS1 genomic tumor aberrations. b) No standard therapy exists or standard therapy has failed. c) No more than 3 prior therapies for metastatic disease
• •Phase 2: At least 1 measurable lesion per RECIST version 1.1
• •Eastern Cooperative Oncology Group (ECOG) performance score of 0 to 2
• •Adequate organ and bone marrow function (Hemoglobin \>9.0 g/dL, Absolute neutrophil count ≥1,500/μL, Absolute lymphocyte count ≥600 and ≤2,500/μL, Platelet count ≥100,000/μL, Total bilirubin ≤1.5 × upper limit of normal, Alanine aminotransferase and aspartate aminotransferase ≤2.5 × ULN, Serum creatinine ≤1.5 × ULN or creatinine clearance \>30 mL/min, Prothrombin time and activated partial thromboplastin time ≤1.5 × ULN)
• •Life expectancy of at least 12 weeks
• •Voluntarily provided a written consent to participate in the study
• •Women of childbearing potential (WOCBP) must have a negative serum pregnancy test within the 7 days before study drug administration
• •WOCBP and sexually active fertile male patients with partners who are WOCBP must agree to use 2 highly effective methods of contraception throughout the course of the study and for 12 weeks after the last dose of study drug.
