• \. Male or female aged 18 years or older.
• \. Has histologically and/or cytologically confirmed unresectable and/or metastatic advanced solid tumor.
• \. Dose Expansion Phase (Phase Ib): Patients with advanced solid tumors who have failed standard treatment, currently have no standard treatment available, or are intolerant to standard treatment, including but not limited to lung cancer, pancreatic cancer, esophageal cancer, liver cancer, breast cancer (triple-negative breast cancer or HER2 low/ultra-low expression breast cancer), ovarian cancer, cervical cancer, and other tumor types.
• Dose Expansion Phase (Phase II): Including but not limited to the following 4 cohorts: ① Lung Cancer Cohort (small cell lung cancer, non-squamous non-small cell lung cancer, squamous cell lung cancer): Failed at least one line of standard treatment; ② Breast Cancer Cohort (triple-negative breast cancer or HER2 low/ultra-low expression breast cancer): Failed at least one line of standard treatment; ③ Ovarian Cancer, Cervical Cancer, Pancreatic Cancer, and Liver Cancer Cohort: Failed at least one line of standard treatment; ④ Esophageal Cancer Cohort: Failed at least one line of standard treatment. There is documentation confirming radiologically confirmed disease progression after the last anti-tumor treatment. If a specific tumor type shows clear anti-tumor activity signals (e.g., meeting the preset efficacy threshold) during the Phase Ib study, the sponsor may initiate an additional dose expansion cohort for the effective tumor type during or after the Phase II study, to further verify its efficacy and safety.
• According to RECIST Version 1.1, there is at least one measurable tumor lesion. (Tumor lesions located in previously irradiated areas or other locally treated sites are generally not considered measurable, unless there is clear evidence of progression of the lesion.)
• Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
• \. Expected survival time of ≥ 3 months.
