Trial Title: Study of the Safety, Pharmacokinetics, and Antitumor Activity of AK104 in Subjects With Advanced Solid Tumors

Study Design Characteristics:
- Allocation: None
- Intervention Model: SINGLE_GROUP
- Observational Model: None
- Primary Purpose: TREATMENT
- Time Perspective: None
- Masking: NONE
- Phase: PHASE1
- Number of Arms: 1.0

Eligibility Criteria:
Inclusion Criteria:~* Written and signed informed consent and any locally required authorization obtained from the subject/legal representative.~* In dose-escalation cohorts (Phase 1a), histologically or cytologically documented advanced or metastatic solid tumor that is refractory/relapsed to standard therapies, or for which no effective standard therapy is available, or the subject refuses standard therapy.~* In the dose-expansion cohorts (Phase 1b), histologically or cytologically confirmed selected advanced solid tumors (to be determined). Subjects must have received no more than three prior lines of systemic therapy for advanced or metastatic disease.~* Subject must have at least one measurable lesion according to RECIST Version1.1.~* Eastern Cooperative Oncology Group (ECOG) Performance Score of 0 or 1.~* Available archived tumor tissue sample to allow for correlative biomarker studies. In the setting where archival material is unavailable or unsuitable for use, the subject must consent and undergo fresh tumor biopsy.~* Adequate organ function.~Exclusion Criteria:~* History of severe hypersensitivity reactions to other mAbs.~* Prior exposure to any anti-PD-1, anti-PD-L1, anti-CTL4 antibody or any other antibody or drug targeting T-cell costimulation or checkpoint pathways such as ICOS, or agonists such as CD40, CD137, GITR, OX40 etc.~* Receipt of any immunotherapy, any conventional or investigational systemic anticancer therapy within 4 weeks prior to the first dose of AK104; in the case of mAbs, 6 weeks prior to the first dose of AK104.~* Any concurrent chemotherapy, immunotherapy, biologic or hormonal therapy for cancer treatment. Concurrent use of hormones for non-cancer-related conditions is acceptable.~* Subjects with a condition requiring systemic treatment with either corticosteroid (\> 10 mg daily prednisone equivalents) or other immunosuppressive medications within 14 days of study drug administration.~* Active or prior documented autoimmune disease within the past 2 years.~* Active or prior documented inflammatory bowel disease (eg, Crohn's disease, ulcerative colitis).~* History of primary immunodeficiency.~* History of organ transplant or hematopoietic stem cell that requires use of immunosuppressives.~* Known allergy or reaction to any component of the AK104 formulation.~* History of interstitial lung disease or non-infectious pneumonitis except for those induced by radiation therapies.~* Any condition that, in the opinion of the investigator, would interfere with evaluation of the investigational product or interpretation of subject safety or study results.~* Known history of tuberculosis.~* Known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS).~* Any positive test for hepatitis B or hepatitis C virus indicating acute or chronic infection except for subjects with HCC.~* An active infection requiring systemic therapy with the exception of anti-viral therapy for hepatitis as specified by the protocol.~* Receipt of live or attenuated vaccination within 30 days prior to the first dose of AK104.
