Clinical Trial Summary

HX008 is a humanized monoclonal antibody targeting PD-1 on the T cell surface, restores T cell activity, thus enhancing immune response, and has the potential to treat various types of tumors. In this study, the tolerance and safety of HX008 in patients with advanced solid tumors will be evaluated.

Eligibility

Inclusion Criteria:

• Provide written informed consent voluntarily. Understand this protocol and be willing and able to adhere to the study visit schedule;
• Male and Female aged =18 are eligible;
• Patients with locally advanced or metastatic solid tumors confirmed by histology or cytology, progressed after the failure of standard treatment, or could not accept/have no standard treatment;
• The patients with ECOG score of 0 or 1;
• The expected survival time is at least 3 months;
• Subjects should have measurable lesions (at least one extracranial lesion) According to RECIST v1.1;
• If the subjects received anti-tumor treatment, they need to meet the following conditions: The interval between whole-body radiotherapy and the first administration in this study was more than 3 weeks, and the interval between local radiotherapy or radiotherapy for bone metastasis and the first administration was more than 2 weeks. No radiopharmaceuticals were taken within 8 weeks before the first administration. The interval between previous chemotherapy or targeted therapy and the first administration of this trial was = 4 weeks or the interval was = 5 half-lives (whichever occurs first); The interval between immunotherapy or biotherapy (tumor vaccine, cytokine, or growth factor controlling cancer) and the first administration of this study was more than 6 weeks;

examination standards:

1. Blood routine: absolute neutrophil count (ANC)=1.5×10^9/L; white blood cell count (WBC)=3×10^9/L; platelet count (PLT)=100×10^9/ L; hemoglobin (HGB)=90 g/L;

2. Renal function: Serum creatinine (Scr) =1.5×ULN;

3. Liver function: TBIL=1.5×ULN; Patients without liver metastases require alanine aminotransferase (ALT) and aspartate aminotransferase (AST) =2.5× ULN. Patients with liver metastases require ALT and AST=5×ULN;

4. The coagulation function is adequate, which is defined as the international normalized ratio (INR) = 2×ULN; or activated partial thromboplastin time (APTT)= 1.5×ULN;

• Reproductive men and women of childbearing age are willing to take effective contraceptive measures from signing the informed consent form to 3 months after the last administration of the trial drug.

Exclusion Criteria:

• Prior malignancy active within the previous 5 years except for locally curable cancers that have been apparently cured, such as carcinoma in situ of the cervix or basal cell skin cancer;
• With adverse reactions of previous treatment that have not recovered to CTCAE V5.0 grade = 1, except for the residual hair loss effect;
• Prior treatment with anti-PD-1/PD-L1/CTLA-4 antibody;
• With active or history of autoimmune diseases that may recur (e.g., systemic lupus erythematosus, rheumatoid arthritis, inflammatory bowel disease, autoimmune thyroid disease, multiple sclerosis, vasculitis, glomerulitis, etc.), or patients with high risk (e.g., organ transplantation requiring immunosuppressive therapy). While those with the following diseases were allowed to be enrolled: a) Stable patients with type I diabetes after a fixed dose of insulin; b) Autoimmune hypothyroidism requiring hormone replacement therapy only; c) Skin diseases requiring no systemic treatment (e.g. eczema, skin rash covering less than 10% of the body surface, psoriasis without ophthalmic symptoms, etc.);
