Investigators
Eligibility Criteria
Inclusion Criteria
- •Age ≥18 years, male or female
- •Patient with histologically or cytologically confirmed advanced malignant solid tumors who have failed standard of care, or has no standard-of-care therapy or are not suitable for standard of care at the present stage;
- •Eastern Cooperative Oncology Group (ECOG) performance status 0 to 1；
- •Life expectancy greater than 3 months;
- •Patient must have at least one measurable tumor lesion as defined by RECIST v1.1; the lesion concerned must not be a bone metastasis if only one target lesion is present;
- •Has adequate organ functions;
- •If the subject is a patient with hepatocellular carcinoma, Child-Pugh classification must be A.
- •A qualified patient (male or female) of childbearing potential must agree to use reliable contraceptive methods (hormonal, or barrier method or abstinence) for the course of the study and through at least 6 months after the last dose; a female patient of childbearing potential must have negative blood pregnancy test within 7 days prior to enrollment;
- •The subject must give his/her informed consent to this study prior to the trial, and voluntarily sign a written informed consent form.
Exclusion Criteria
- •Histopathological confirmed head and neck cancer or squamous-cell lung cancer, or bleeding tendency in the tumor lesion judged by the investigator;
- •Has received antitumor therapy like radiotherapy, chemotherapy, targeted therapy, endocrinal therapy or immunotherapy, or other clinical study drug therapy within 4 months prior to the initial drug administration;
- •Has received a surgical operation on major viscera or experienced apparent trauma within 4 weeks from the initial drug administration, or experienced subcutaneous venous access device implantation within 7 days;
- •The adverse reactions which occurred in the previous antitumor treatment were not recovered to ≤ grade 1 based on CTCAE 4.03 assessment (except for hair loss);
- •Evidences of metastatic lesion in the patient's central nervous system;
- •Previously experienced ≥ grade 3 immune-related adverse event during immunotherapy;
- •Active, or history of autoimmune disease which may relapse (for example, systemic lupus erythematosus, rheumatoid arthritis, vasculitis, etc.);
- •Currently having or have had interstitial lung disease;
- •Uncontrollable active infection(s);
- •History of immunodeficiency, including HIV antibody positive;
Arms & Interventions
HLX04+HLX10
HLX10, at three dose levels (1, 3, 10 mg/kg), to be intravenously injected once every two weeks; HLX04, at a fixed dose of 5 mg/kg, intravenously injected once every two weeks; Study drugs given in combination for up to 2 years or until the disease gets worse, whichever comes first.
Intervention: HLX04
HLX04+HLX10
HLX10, at three dose levels (1, 3, 10 mg/kg), to be intravenously injected once every two weeks; HLX04, at a fixed dose of 5 mg/kg, intravenously injected once every two weeks; Study drugs given in combination for up to 2 years or until the disease gets worse, whichever comes first.
Intervention: HLX10
Outcomes
Primary Outcomes
Dose Limiting Toxicity (DLT) of HLX04 plus HLX10 in patients with advanced solid tumors
Time Frame: 28 days
DLT is defined as the occurrence of the following adverse events (unless judged by the investigator to be definitely unrelated to HLX04 or HLX10) within Cycle 1 (i.e., from Cycle 1 Day 1 to Cycle 1 Day 28)
Maximum Tolerated Dose (MTD) of HLX04 plus HLX10 in patients with advanced solid tumors
Time Frame: 28 days
The MTD is the dose with toxicity rate (estimated by isotonic regression) most approximate to the target one (30%).
Secondary Outcomes
- Overall Survival (OS) of HLX04 plus HLX10 in patients with advanced solid tumors(Day 1 of treatment up to 2 years)
- Immunogenicity(Day 1 of treatment up to 2 years)
- Disease Control Rate (DCR) of HLX04 plus HLX10 in patients with advanced solid tumors(Day 1 of treatment up to 2 years)
- Objective Response Rate (ORR) of HLX04 plus HLX10 in patients with advanced solid tumors(Day 1 of treatment up to 2 years)
- PK parameters of the HLX04 plus HLX10 therapy in patients with advanced solid tumors(Day 1 of treatment up to 2 years)
- Progression-Free Survival (PFS) of HLX04 plus HLX10 in patients with advanced solid tumors(Day 1 of treatment up to 2 years)
- Duration of Response (DOR) of HLX04 plus HLX10 in patients with advanced solid tumors(Day 1 of treatment up to 2 years)
