This is a Phase II study being done at several hospitals without using a placebo. It will look at how safe and tolerable the drug WGI-0301 is when given together with nivolumab, how the body processes and responds to WGI-0301, and whether this combination shows early signs of working in people with advanced liver cancer or advanced kidney cancer.

Inclusion Criteria:

• 1) Age 18-75 (inclusive) on the day of singing informed consent, male or female.

  2) Voluntarily agree to provide signed informed consent and are willing and able to comply with all aspects of the protocol 3) Subjects in each disease cohorts will need to fulfill the following criteria:

  • HCC Cohort:

  1. Histologically or cytologically confirmed diagnosis of HCC, or clinical diagnosis of HCC as per American Association for the Study of Liver Diseases (AASLD) criteria

  2. 4. Barcelona Clinic Liver Cancer (BCLC) Stage C, or BCLC Stage B that is not suitable for any curative surgeries or locoregional therapy

  3. Child-Pugh Liver Function Class A or Class B (score ≤ 7)

  4. Documented first-line standard treatment failure (disease progression or intolerance)；

     • nccRCC Cohort：Histologically or cytologically confirmed diagnosis of nccRCC，that is locally advanced or with distant metastasis, and have not received any prior systemic antitumor therapy. If disease progression occurs within 6 months after the last dose of adjuvant therapy, it is considered a failure of first-line treatment and thus does not meet the criteria.

     • ccRCC Cohort：Histologically or cytologically confirmed ccRCC, with locally advanced unresectable disease or distant metastasis, and disease progression or intolerance after prior first-line therapy. Patients who have received adjuvant or neoadjuvant therapy may also be screened if they meet the above criteria.

       4) Eligible for treatment with Nivolumab as determined by investigators according to the Package Insert and clinical judgment.

       5) Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) of 0 or 1 within 7 days prior to the first dose of study intervention 6) Life expectancy in the judgement of the Investigator > 12 weeks. 7) Patients must have at least one measurable lesion according to RECIST 1.1 as determined by the investigator, and that has not been the target of local or regional therapy such as radiotherapy; a new area of tumor progression within or adjacent to a previously treated lesion, if clearly measurable by a radiologist, is acceptable.

       8) Any adverse events (AEs) related to prior anti-tumor therapy must have resolved to ≤ Grade 1 (CTCAE v6.0). However, patients may still be screened if the investigator determines that the toxicity is well-controlled and does not affect the patient's safety or compliance with the study drug, and this has been confirmed with the sponsor.

       9) Collection of an archived tissue sample will be requested (where available) or agree to undergo tumor tissue biopsy for biomarker testing; however, a subject will not be precluded from participating in the study if tissue sample is not available for collection or is otherwise insufficient for analysis.

       10) Patients must have adequate organ function as defined below:

     • For patients with no liver metastasis or lesion: AST and ALT ≤2.0× ULN, and total bilirubin ≤1.5×ULN; For patients with liver metastasis or lesion: AST and ALT ≤3.0× ULN, and total bilirubin ≤2×ULN; For patients with Gilbert Syndrome: Total bilirubin ≤3×ULN

     • Serum albumin≥30g/L

     • Creatinine Clearance (CrCL) ≥50 mL/min (Cockcroft-Gault formula: Ccr=(140-Age)×body weight (Kg)/72×Scr（mg/dl）{×0.85 for female subject}

Subjects with chronic HBV infection must have HBV DNA < 500 IU/ mL, and should be managed according to treatment guidelines. Those on antiviral therapy at screening should have been treated for >2 weeks before the first dose

     • HCV-HCC: • HCV-HCC: Resolved HCV infection (as evidenced by detectable HCV RNA or antibody), or stable HCV infection (such as normal LFTs or being asymptomatic). Patients with positive HCV RNA requiring direct antiviral agent treatment, or those with HBV and HCV co-infection are excluded 12) Women of child-bearing potential (WOCBP) must have a negative serum pregnancy within 3 days prior to receiving the first dose of study medication and must use accepted highly effective methods of contraception from the time of signing the informed consent through 6 months after the last dose of study drug.
