A Study to Evaluate the Safety, Tolerability, Pharmacokinetics and Preliminary Anti-Tumor Activity of the Oral Anaplastic Lymphoma Kinase (ALK)/Epidermal Growth Factor Receptor (EGFR) Inhibitor Brigatinib (AP26113)

Inclusion Criteria

General Eligibility Criteria

• All participants must have tumor tissue available for analysis. If sufficient tissue is not available, participants must undergo a biopsy to obtain adequate samples. For participants in expansion cohorts 2, 3 and 5, for whom failure of prior therapy is specified (crizotinib for cohorts 2 and 5, one epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI) for cohort 3), tumor tissue must be available following failure of the prior therapy.
• Must have measurable disease by Response Evaluation Criteria in Solid Tumors (RECIST).
• Male or female participants ≥ 18 years old.
• Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1.
• Minimum life expectancy of 3 months or more.
• Adequate renal and hepatic function.
• Adequate bone marrow function.
• Normal QT interval on screening electrocardiogram (ECG) evaluation.
• For females of childbearing potential, a negative pregnancy test must be documented prior to enrollment.
• Female participants who are of childbearing potential and fertile male participants must agree to use an effective form of contraception with their sexual partners throughout study participation.
• Signed and dated informed consent indicating that the participant has been informed of all pertinent aspects of the study.
• Willingness and ability to comply with scheduled visits and study procedures.

Cohort-specific Eligibility Criteria

PART 1: Dose Escalation Phase:

• Histologically confirmed advanced malignancies. All histologies except leukemia;
• Refractory to available therapies or for whom no standard or available curative treatments exist;
• Tumor tissue available for analysis.

PART 2: Expansion cohorts (5 additional cohorts):

• Expansion cohort 1: Non-small cell lung cancer (NSCLC) participants whose tumors exhibit anaplastic lymphoma kinase (ALK) rearrangements and who have not been treated with previous ALK inhibitors.

i. Histologically or cytologically confirmed NSCLC; ii. Tumor tissue available for analysis (see General Eligibility Criterion 1; iii. History of ALK rearrangement by fluorescence in situ hybridization (FISH); iv. No prior ALK inhibitor therapy; 2. Expansion cohort 2: NSCLC participants whose tumors exhibit ALK rearrangements and who are resistant to crizotinib: i. Histologically or cytologically confirmed NSCLC; ii. Tumor tissue available for analysis (see General Eligibility Criterion 1); iii. History of ALK rearrangement by FISH; iv. Resistant to crizotinib (and have not received any other prior ALK inhibitor therapy); 3. Expansion cohort 3: NSCLC participants whose tumors exhibit an epidermal growth factor receptor EGFR-T790M mutation and who are resistant to 1 prior EGFR TKI: i. Histologically or cytologically confirmed NSCLC ii. Previous treatment with only 1 EGFR TKI for which the last administration was within 30 days of the initiation of brigatinib; iii. Documented evidence of an EGFR-T790M mutation following disease progression on the most recent EGFR TKI therapy; iv. No intervening systemic therapy between cessation of the EGFR TKI and initiating brigatinib; v. Tumor tissue available for analysis (see General Eligibility Criterion 1). 4. Expansion cohort 4: Participants with any cancers with abnormalities in ALK or other brigatinib targets. Examples include, but are not limited to, anaplastic large cell lymphoma (ALCL), diffuse large-cell lymphoma (DLCL), inflammatory myofibroblastic tumors (IMT), and other cancers with ALK abnormalities, or tumors with ROS1 fusions: i. Histologically confirmed lymphomas and other cancers, with the exception of leukemias; ii. Tumor tissue available for analysis (see General Eligibility Criterion 1). 5. Expansion Cohort 5: NSCLC participants whose tumors exhibit ALK rearrangements and who have active, measurable brain metastases: i. Histologically or cytologically confirmed NSCLC: ii. Tumor tissue available for analysis (see General Eligibility
