Inclusion Criteria: * Trial participant voluntarily participates in this study and provides signed written informed consent form (ICF). * Histologically or cytologically confirmed advanced malignancy (locally advanced unresectable or metastatic). * Trial participant is aged ≥ 18 years at the time of signing the ICF. * For trial participants previously treated with an ALK-TKI: subjects are eligible for enrollment if they have a report of ALK-positive result from local laboratory testing \[fluorescence in-situ hybridization (FISH), immunohistochemistry (IHC) (Ventana assay), reverse-transcription polymerase chain reaction (RT-PCR), next-generation sequencing (NGS), and other assays\] using tumor tissue or blood sample obtained within 1 year prior to informed-consent signature. In the absence of such positive report, subjects must provide either non-irradiated archival tissue (collected within 1 year) or fresh biopsy tissue, or fresh blood sample (fresh biopsy tissue and fresh blood are preferred). ALK positivity (ALK fusion and/or other meaningful mutations) must be confirmed by NGS testing performed at the central laboratory for eligibility. For trial participants with no prior ALK-TKI treatment: subjects are eligible for enrollment if they have a prior report of ALK-positive result from local laboratory testing of tumor tissue or blood sample. In the absence of such positive report, subjects must provide either non-irradiated archival tissue or fresh biopsy tissue, or fresh blood sample (fresh biopsy tissue and fresh blood are preferred). ALK positivity must be confirmed by NGS testing performed at the central laboratory for eligibility. Note: Requirements for tumor tissue and blood sample testing are detailed in the \*Central Laboratory Operations Manual. * Phase Ia will enroll trial participants with ALK-positive advanced malignancies who are pretreated. Pretreated is defined as disease progression or intolerance following standard systemic anti-tumor therapy for advanced disease (recommended by clinical oncology practice standards including Chinese Society of Clinical Oncology (CSCO) guidelines and expert consensus); intolerance is defined as recurrence of Grade ≥3 adverse events despite adequate symptomatic treatment with well-documented evidences (corresponding laboratory findings or original medical records from that episode). Phase Ib will enroll two cohorts: Cohort 1: ALK-positive advanced NSCLC previously treated with any second- and/or third-generation ALK-TKI (including investigational agents not yet marketed); Cohort 2: Other pretreated ALK-positive advanced malignancies. Phase Ⅱ will enroll five cohorts: Cohort 1: ALK-positive advanced NSCLC previously treated with any second-generation ALK-TKI (including investigational agents not yet marketed); Cohort 2: ALK-positive advanced NSCLC previously treated with any third-generation ALK-TKI (including investigational agents not yet marketed); Cohort 3: ALK-positive advanced NSCLC previously treated with both second- and third-generation ALK-TKIs (including investigational agents not yet marketed); Cohort 4: ALK-positive advanced NSCLC without prior exposure to any ALK-TKI (including investigational agents not yet marketed); Cohort 5: Other ALK-positive advanced malignancies. * At least one measurable extracranial target lesion per RECIST Version 1.1 (for solid tumors) or other standard tumor response assessment criteria (e.g., the Lugano criteria for trial participants with lymphoma).
