Who can join

Age: 18 and older. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Diagnosis of HCC confirmed by histology or according to the American Association for the Study of Liver Disease (AASLD) criteria
• a. Availability of tumor tissue samples prior to the first day of study treatment is required for all patients.
• HCC that is amenable to R0 resection with curative intent as determined by treating surgical/medical oncologists in consultation with the principal investigator. Subject must be a suitable candidate for surgery based on evaluations by the treating surgeon/oncologist.
• Measurable disease according to RECIST 1.1
• No prior anti-PD (Programmed death)-1/L1 therapies for any indication
• Age ≥18
• Eastern Cooperative Oncology Group (ECOG) Performance Status 0-1
• Child Pugh A
• Adequate organ and marrow function as defined below:
• ANC (absolute neutrophil count) ≥ 1.5 x 109/L (does not apply to patients with benign ethnic neutropenia)
• Platelets ≥ 75 x 109/L without transfusion
• Hemoglobin ≥ 9 g/dL without transfusion within 2 weeks of screening
• ALT (Alanine Aminotransferase) ≤ 3 2 x ULN (Upper Limit of Normal)
• Bilirubin ≤ 3 x ULN
• Creatinine clearance ≥ 50 mL/min calculated by the Cockcroft-Gault formula using actual body weight
• All etiologies of chronic liver disease including but not limited to Hepatis C Virus (HCV) or Hepatis B Virus (HBV) infection. HCV and HBV infection status does not preclude eligibility as long as patients meet all other eligibility criteria but must be known prior to starting treatment. Patients with HBV must be on anti-viral therapy prior to the first day of investigational drug treatment. Patients with HCV may include active or resolved infection.
• All men, as well as women of child-bearing potential must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 3 months following the last dose of ateganosine or 4 months following the last dose of cadonilimab. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
• A female of child-bearing potential is any woman (regardless of sexual orientation, marital status, having undergone a tubal ligation, or remaining celibate by choice) who meets the following criteria:
• Has not undergone a hysterectomy or bilateral oophorectomy; or
• Has not been naturally postmenopausal for at least 12 consecutive months (i.e., has had menses at any time in the preceding 12 consecutive months).
• Ability to understand and the willingness to sign a written informed consent.
• Willing and able to comply with the requirements and restrictions in this protocol.

You may not qualify if…

• Presence of extrahepatic extension of disease
• Prior locoregional therapy to target lesions is not allowed. History of curative locoregional therapy is allowed provided the following are met: 1) previously treated tumor is not viable without evidence of residual disease for at least 12 months, and 2) patient has not received local therapy in the past 12 months.
• Known fibrolamellar HCC or combined HCC-cholangiocarcinoma histology
• History of hepatic encephalopathy
• Severe ascites requiring paracentesis in the past 3 months
• Subjects may not be receiving any other investigational agents for the treatment of the cancer under study
• Prior significant bleeding event in the past 3 months that may pose a surgical risk
• History of trauma or major surgery within 28 days prior to the first dose of study drug administration. (Tumor biopsy or placement of central venous access catheter (eg, port or similar) is not considered a major surgical procedure)
• Underlying medical conditions that, in the investigator's opinion, will make the administration of study drugs hazardous, including but not limited to:
• Autoimmune interstitial lung disease (lymphangitic spread of cancer is not disqualifying or stable/chronic lung disease that is not likely to be autoimmune in nature and progressive),
• Active viral, bacterial, or fungal infections requiring parenteral treatment within 14 days of the initiation of study drugs,
• Clinically significant cardiovascular disease,
• A condition that may obscure the interpretation of toxicity determination or AEs,
• History of prior bone marrow and/or solid-organ transplantation
• Hypersensitivity to IV contrast; not suitable for pre-medication
• Any active autoimmune disease or a documented history of autoimmune disease or syndrome that required systemic treatment in the past year (ie, with use of disease-modifying agents, corticosteroids, or immunosuppressive drugs), with the following exceptions:
• Autoimmune diseases with only dermatologic involvement such as eczema, vitiligo, lichen chronicus, or resolved childhood asthma/atopy which involves less than 10% of the body surface area and symptoms are well controlled on topical treatments without recent exacerbations requiring other therapies
• Replacement therapy (eg, thyroxine, insulin, or physiologic corticosteroid replacement therapy for thyroid, adrenal or pituitary insufficiency) is not considered a form of systemic treatment
• Participants with asthma who require intermittent use of bronchodilators, inhaled corticosteroids, or local corticosteroid injections will not be excluded from this study
• Subjects with a condition requiring systemic treatment with either corticosteroids (> 10 mg/day prednisone equivalent) or other immunosuppressive medications within 14 days of study administration. Inhaled or topical steroids and adrenal replacement doses ≤10 mg/day prednisone equivalents are permitted in the absence of autoimmune disease.
• Prior malignancy that required systemic treatment within the previous 2 years except for locally curable cancers that have been apparently cured, such as basal or squamous cell skin cancer, superficial bladder cancer, or carcinoma in situ of the cervix, breast, or prostate cancer. Patients with a cancer history with a low risk of recurrence or progression may be enrolled as determined by the principal investigator.
• Prisoners or subjects who are involuntarily incarcerated
• Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after contraception and until the termination of gestation, confirmed by a positive hCG (Human chorionic gonadotropin) laboratory test
• Has known psychiatric or substance abuse disorders that would interfere with cooperation with the requirements of the trial
• Evidence of bleeding diathesis or significant coagulopathy
