This is a Phase I/II, open-label, preliminary study of safety, tolerability, pharmacokinetics, and efficacy. The study comprises three parts: a Dose Escalation cohort, a Dose Expansion cohort, and an Efficacy Expansion cohort.

Dose Escalation cohort aims to evaluate the safety, tolerability, pharmacokinetic (PK) characteristics, and preliminary efficacy of WJ22096 Tablets in patients with advanced solid tumors for whom standard therapies have failed, are not tolerated, or for whom no standard therapy exists.

Dose Expansion cohort Based on an evaluation of preliminary data, the Sponsor and the Safety Monitoring Committee (SMC) will select 1-2 dose levels to further evaluate preliminary efficacy, safety, tolerability, and PK characteristics, and to confirm the Recommended Phase 2 Dose (RP2D). Each dose cohort will enroll approximately 9-12 subjects with advanced solid tumors (for whom standard therapies have failed, are not tolerated, or for whom no standard therapy exists), predominantly comprising patients with Non-Small Cell Lung Cancer (NSCLC), Colorectal Cancer (CRC), and Pancreatic Cancer.

Efficacy Expansion cohort aims to evaluate the efficacy, safety, tolerability, and PK characteristics at the selected dose in patients with specific tumor types, such as NSCLC, CRC, and Pancreatic Cancer. The dosing regimen will be the RP2D determined during the Dose Escalation and Dose Expansion cohorts. It is initially planned to expand 2-3 cohorts using Simon's two-stage minimax design, with approximately 20-40 subjects planned for enrollment in each cohort. (The specific tumor types for expansion, sample size, and number of cohorts will be adjusted by the Principal Investigator (PI) and the Sponsor based on results from the preceding stages of the trial).
