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. If unavailable or unsuitable, the subject must consent and undergo fresh tumor biopsy.
* Adequate organ function.
* Subjects with central nervous system (CNS) metastases must have been treated, be asymptomatic.
* Females of childbearing potential and non-sterilized males who are sexually active must use an effective method of contraception from screening until 120 days after final dose of investigational product or women of non child bearing potential.
* Life expectancy =12 weeks.
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.
* Prior malignancy active within the previous 3 years except for the tumor for which a subject is enrolled in the study, and locally curable cancers that have been apparently cured, (e.g. basal cell skin cancer, or carcinoma in situ of the cervix or breast).
* For subjects enrolled in the dose escalation phase, having received prior anti-PD-1, anti-PD-L1, anti-CTLA-4 or any other immunotherapy or immune-oncology (IO) agent within 28 days of commencing treatment with AK112 or experienced a toxicity that led to permanent discontinuation of prior immunotherapy. All AEs while receiving prior immunotherapy have not completely resolved or resolved to Grade 1 prior to screening, required the use of additional immunosuppression other than corticosteroids
* Receiving any immunotherapy, conventional or investigational systemic anticancer therapy within 4 weeks prior to the first dose
* Any concurrent chemotherapy, immunotherapy, biologic or hormonal therapy for cancer treatment (hormones use for non-cancer related conditions is acceptable).
* Subjects with clinically significant cardiovascular disease
* Subjects with a condition requiring systemic treatment with either corticosteroid (> 10 mg daily ) or other immunosuppressive medications within 2 weeks of study drug administration.
* Current or recent use of aspirin (> 325 mg/day) or treatment with dipyramidole, ticlopidine, clopidogrel, and cilostazol.
* Current unstable of full-dose oral or parenteral anticoagulants or thrombolytic agents for > 2 weeks prior to the first dose of AK112
* Active or prior documented autoimmune disease within the past 2 years or conditions not expected to recur in the absence of an external trigger)
* Active or prior documented inflammatory bowel disease
* History of primary immunodeficiency.
* History of organ transplant.
* Known allergy or reaction to any component of the AK112 formulation.
* History of interstitial lung disease or non-infectious pneumonitis except for those induced by radiation therapies.
* Unresolved toxicities from prior anticancer therapy, defined as having not resolved to NCI CTCAE v5.0 Grade 0 or 1
* Major surgical procedure within 30 days prior to the first dose of AK112 or still recovering from prior surgery.
* Known history of HIV.
* Known active hepatitis B or C infections. Note: Subjects with HCC and positive HBsAg result are eligible if the subjects were treated with antiviral therapy and HBV viral load less than 500 IU/mL prior to first dose of AK112.
* An active infection requiring systemic therapy
* Received live attenuated vaccination within 30 days prior to the first dose of AK112.
