• Dose expansion phase:
• Part 1
• Patients (HCC, renal cell carcinoma, endometrial cancer, gastric adenocarcinoma or gastroesophageal junction adenocarcinoma, colorectal adenocarcinoma, cervical cancer, NSCLC) should have PD or intolerable toxicity after 1 standard treatment, or cannot receive standard treatment (such as economic limitations or patient's wishes, etc.). Among them, requirements of standard treatment are defined as follows:

• Patients with renal cell carcinoma who have received 1 standard systemic antitumor therapy (sunitinib, sorafenib, pazopanib, axitinib, cabozantinib, bevacizumab plus IFN-α, temsirolimus);
• Patients with endometrial cancer who have received ≤2 line of platinum-based double drug systemic antitumor therapy (excluding hormonal therapy) and had PD or Grade ≥3 SAE, or had recurrence or PD after completion of at least 4 cycles of platinum-based double drug chemotherapy. Patients with recurrence or metastasis during or within 12 months after completion of neoadjuvant/adjuvant chemotherapy with platinum-based regimen are considered to have received first-line treatment (4 cycles are required for neoadjuvant/adjuvant chemotherapy, and if less than 4 cycles, it is also eligible to have PD or Grade ≥3 SAE during the treatment);
• Patients with cervical cancers who have recurrent or metastasized squamous cell carcinoma, adenocarcinoma, or adeno-squamous carcinoma after at least one line of platinum-based chemotherapy (patients are considered to have received first-line treatment if they have recurrent or metastasized during or within 6 months after platinum-based neoadjuvant or adjuvant chemotherapy);

Other non-squamous NSCLC patients can be included if they have a prior test report demonstrating no driver gene mutation/rearrangement (EGFR, ALK, ROS1); if there is no prior corresponding gene report, archived or fresh tissue needs to be collected for testing at the study site, or at the central laboratory arranged by sponsor.
