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.
* 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.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
* History of severe hypersensitivity reactions to other mAbs.
* For dose-escalation phase (Phase 1a), prior exposure to any anti-PD-1, anti-PD-L1, anti-CTL4 antibody. For dose-expansion phase (Phase 1b), 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 AK105.
* Prior treatment with systemic immune modulating agents (other than agents specified above) that was within 28 days prior to enrollment, or within 90 days prior to enrollment if there was an immune related adverse event, or associated with toxicity that resulted in discontinuation of the immune modulating agent.
* 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 AK105 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).
* Known active hepatitis B or C infections, or any positive test at screening for hepatitis B or C virus indicating acute or chronic infection except for subjects with HCC. Subjects with past or resolved HBV infection are eligible. Subjects positive for HCV antibody are eligible only if qualitative HCV RNA tests is negative.
* An active infection requiring systemic therapy with the exception of antiviral therapy for hepatitis as specified by the protocol.
* Receipt of live or attenuated vaccination within 30 days prior to the first dose of AK105.
* Active or prior documented esophageal or gastric variceal bleeding
* Clinically apparent ascites on physical examination. Ascites that requires active ongoing paracentesis (within 6 weeks prior to the first scheduled dose) to control symptoms. Note: ascites detectable on imaging studies only are allowed.
* Portal vein invasion at the main portal (Vp4), inferior vena cava, or cardiac involvement of HCC based on imaging.
* Clinically diagnosed hepatic encephalopathy characterized by asterixis.
