Brief summary: This is a phase I/II, open-label and multi-center study of SY-3505, a third-generation ALK TKI, in patients with advanced ALK-positive non-small cell lung cancer (ALK-positive NSCLC).

Detailed description: The study consists of two parts:

Part 1: Dose-escalation and dose-expansion in patients with advanced ALK-positive NSCLC, including 9 SY-3505 dose levels.

Dose-escalation study phase is designed to determine the dose-limiting toxicity (DLT) according to a 3+3 design and recommended phase II dose (RP2D) and to characterize the safety, tolerability, and pharmacokinetics (PK) profile of SY-3505. Other dose regimens may be explored based on the analysis of emerging PK and safety data. At this study phase, SY-3505 administered orally once daily (QD) in 28-day treatment cycles to adult patients with ALK-positive NSCLC. Dose-expansion study is designed to evaluate the antitumor activity (ORR, DCR and DoR) of SY-3505 at selected doses in ALK-positive NSCLC patients who have received at least 1 prior ALK TKI therapy.

Part 2: Phase 2 study to evaluate the efficacy of SY-3505.

This phase is designed to determine the antitumor activity (ORR, DCR, DoR, PFS and OS), safety, and PK of SY-3505 at RP2D in ALK-positive NSCLC patients who have received alectinib only or ≥2 prior ALK TKIs.

Eligibility criteria: Inclusion Criteria:

1. Male or female, age ≥ 18 years at the time of screening.
2. Must have an Eastern Cooperative Oncology Group (ECOG) performance status ≤ 1.
3. Estimated Life expectancy ≥ 12 weeks.
4. Must have either at least one measurable lesion with no prior local treatment or measurable lesions with definite progression (Bone metastases alone were not accepted) after local treatment per Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1.
5. Dose-escalation phase: patients must have histological or cytological confirmed ALK-positive advanced NSCLC. Dose-expansion phase: patients must have histological or cytological confirmed ALK-positive advanced NSCLC and progressed after at least one prior line of ALK TKI therapy. Phase II: patients must have histological or cytological confirmed ALK-positive advanced NSCLC and progressed after only alectinib or ≥2 prior ALK TKIs treatment. The pathological report requires either positivity for ALK gene expression determined by fluorescence in-situ hybridization (FISH) assay, immunohistochemistry (IHC), reverse transcription-polymerase chain reaction (RT-PCR), next-generation sequencing (NGS) or other identified methods from previous reports and provide tissue for ALK retest if possible or providing tissue for ALK test if no previous report is available.
6. Patients without brain metastasis or with asymptomatic brain metastases (no need for intervention or stable more than 4 weeks after treated).
7. Adequate organ function within 10 days prior to the study of treatment as defined in the below:

   Hepatic function

   Total serum bilirubin (TBIL) ≤ 1.5 times upper limit of normal (ULN); Aspartate transaminase (AST), alanine transaminase (ALT) and γ- glutamyltransferase (GGT) ≤ 2.5 times ULN if no demonstrable liver metastases, or otherwise ≤ 5 times ULN.

   Bone marrow function

   Absolute neutrophil count (ANC) ≥ 1.5 x 10⁹/L; Platelets (PLT) count ≥ 100 x 10⁹/L; Hemoglobin (Hb) ≥ 90 g/L.

   Renal function

   Creatinine clearance ≥ 60 mL/min.

   Pancreatic function

   Serum total amylase ≤1.5 times ULN; Serum lipase ≤ 1.5 times ULN.

   Blood glucose

   Fasting Blood Glucose (FBG) ≤ 200 mg/dL (11.1 mmol/L).

   Serum lipid

   Serum cholesterol ≤ 500 mg/dL (12.92 mmol/L).

   Cardiac function

   Left ventricular ejection fraction (LVEF) ≥ 50%.
8. Any toxicity of previous antineoplastic treatments was restored to ≤ 1 (except hair loss).
9. Female patients with reproductive potential must have a negative serum pregnancy test, male and female patients of childbearing potential must be willing to completely abstain or agree to use an appropriate method of contraception during the entire study duration and for at least 3 months after the last dose of study medication.
10. Willingness and ability to give informed consent and follow protocol procedures, and comply with follow-up visit requirements.
