Eligibility
Key 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.

Key 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.

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.

Summary
Brief summary
This study is to characterize the safety, tolerability, pharmacokinetics (PK),
immunogenicity, pharmacodynamics (PD) and anti-tumor activity of AK104 as a single agent in
adult subjects with advanced solid tumor malignancies. The study consists of a dose
escalation phase (Phase 1a) to determine the maximum tolerated dose (MTD), or recommended
Phase 2 dose (RP2D) for AK104 as a single agent, and a dose expansion phase (Phase 1b) which
will characterize treatment of AK104 as a single agent at the MTD or RP2D.
