Eligibility Criteria

Inclusion Criteria

• Able to understand and willing to sign the Informed Consent Form(ICF).
• Male or female ≥ 18years.
• Subjects with histologically or cytologically confirmed advanced-stage or metastatic tumor must have received, or be intolerant to all available approved or standard therapies known to confirmed clinical benefit, or for whom standard therapy does not exist.
• Must have adequate organ function, prior to start of 609A, including the following:

1. Bone marrow reserve: absolute neutrophil count (ANC) ≥ 1.0 ×109/L; platelet count≥ 100 × 109/L; hemoglobin ≥ 9 g/dL or ≥ 5.6 mmol/L;

2. Hepatic: total bilirubin ≤ 1.5 times the upper limit of normal (ULN), aspartate transaminase (AST) and/or alanine aminotransferase (ALT) ≤ 3 × ULN (≤5 × ULN if with liverinvolvement)

3. Renal: serum creatinine ≤1.5 times the ULN or estimated creatinineclearance

≥50mL/min (Cockroft and Gault formula [http://www.mdcalc.com/creatinine-clearance-cockcroft-gault-equation/]).

4. Coagulation tests INR≤ 2 (Exception: INR 2 to ≤ 3 is acceptable for subjects onWarfarin anticoagulation), activated partial thromboplastin time (aPTT) ≤ 1.5 × ULN

• Regarding prior anti-tumortherapy:

1. Subjects who have received any anticancer drugs approved or investigational, including chemotherapy, immune therapy, hormonal therapy (Exceptions: hormone-replacement therapy, testosterone or oral contraceptives), biologic therapy, must have stopped treatment at least 3 weeks, or five half-lives, whichever is shorter, before first dose of 609A.

2. Generalized radiation therapy must have stopped 3 weeks before first dose of 609A, or local radiotherapy or radiation therapy for bone metastases must have stopped 2 weeks before first dose of 609A. No therapeutic radiopharmaceuticals are taken within 8 weeks before first dose of 609A.

3. Subjects who have received prior immunotherapies targeting T cell stimulation such as (e.g. anti-PD-1, anti- PD-L1 or anti-CTLA-4) must have stopped treatment for at least 4 weeks before first dose of 609A.

• Female patient with fertility or male patient whose partner has fertility should use one or more contraceptive methods for contraception from the screening period to five half-lives after the last treatment. These measures include, but are not limited to, oral or implantable injections of hormonal contraceptives; intrauterine birth control ring or placement of intrauterine system (IUS) hormone-releasing intrauterine device; or use of barrier methods such as condoms or septum and spermicide products. Women of childbearing potential must have a negative pregnancy test ≤ 72 hours prior to the first dose of study drug.

Postmenopausal women must have been amenorrhoeic for at least 12 months to be considered of non-childbearing potential.

• According to RECIST1.1, the subject should have an assessable lesion (target lesion or non- target lesion)
• According to RECIST1.1, the subject should have an assessable lesion (target lesion or non- target lesion) ECOG score 0, 1 or 2 point.

Exclusion Criteria

• Subjects who meet any of the following criteria cannot be enrolled: Life expectancy < 3 months.
• Any remaining AEs > grade 1 from prior anti-tumor treatment as per CTCAE v5. 0, with exception of the residual hair loss;
• Any remaining AEs > grade 1 from prior anti-tumor treatment as per CTCAE v5. 0, with exception of the residual hair loss; Any involvement of CNS excluded except: Based on screening brain magnetic resonance imaging (MRI), patients must have one of the following:

1. No evidence of brain metastases or has to be clinically stable for at least 4 weeks

2. Untreated brain metastases not needing immediate localtherapy

• Pregnant or nursing females
• Subjects who have had major surgery within the 21-days from the screening;
• Subjects with history of interstitial lung disease or idiopathic pulmonary fibrosis or unresolved active or chronic inflammatory pulmonary disease are excluded. Subjects with a history of radiation pneumonitis which has resolved areeligible.
• HIV infection.
• Active hepatitis B or C. HBV carriers without active disease (HBV DNA titer< 1000 cps/mL or 200 IU/mL) or cured Hepatitis C (negative HCV RNA test) may been rolled.
• History of primary immunodeficiency, stem cell or organ transplant, or previous clinical diagnosis of tuberculosisdisease.
• History of life-threatening hypersensitivity or known to be allergic to protein drugs or recombinant proteins or excipients in 609A drug formulation.
• Acute or chronic uncontrolled renal disease, pancreatitis or liver disease (per investigator assessment).
• Subjects with any type of primary immunodeficiencies will be excluded from thestudy.
• Subjects with condition requiring systemic treatment with either corticosteroids (>15 mg/day prednisone or equivalent) or other immunosuppressive medications within 14 days before the planned first dose of study drug. Inhaled or topical steroids, and adrenal replacement steroid doses ≤ 10 mg daily prednisone equivalent are permitted in the absence of activeautoimmune disease. Ophthalmologic, nasal and intra-articular injections of steroids areacceptable.
• Subjects who experienced immunotherapy-related adverse events (irAE) grade ≥ 3, or who had to discontinue prior anti-PD-1, anti-PD-L1, or CTL4 treatment due to irAEs of any grade.
• Severe or uncontrolled cardiac disease requiring treatment, congestive heart failure NYHA III or IV, unstable angina pectoris even if medically controlled, history of myocardial infarction during the last 6 months, ECG QTcF (Fridericia)≥450 msec for male or QTcF (Fridericia)≥470 msec for female, serious arrhythmias requiring medication (with exception of atrial fibrillation or paroxysmal supraventricular tachycardia).
• Hypertension (defined as sustained systolic blood pressure> 160 mm Hg and / or post- diastolic blood pressure with antihypertensive drugs> 100 mmHg;
• Any other serious underlying medical (e.g. uncontrolled diabetes mellitus, active uncontrolled infection, active gastric ulcer, uncontrolled seizures, cerebrovascular incidents, gastrointestinal bleeding, severe signs and symptoms of clotting disorders), psychiatric, psychological, familial or geographical condition that, in the judgment of the investigator, may interfere with the planned staging, treatment and follow-up, affect subject compliance or place the subject at high risk from treatment-related complications.
• Has received a live and attenuated vaccine within 28 days prior to the first dose of study drug.
• Patients who had received treatment with any herbal or alternative therapies or Chinese prepared medicine within 7 days prior to the first dose of the studydrug.
• Subjects with active autoimmune diseases or history of autoimmune diseases should be excluded; these include but are not limited to subjects with a history of immune related neurologic disease, multiple sclerosis, autoimmune (demyelinating) neuropathy, Guillain- Barre syndrome, myasthenia gravis, systemic lupus erythematosus (SLE), connective tissue diseases, scleroderma, inflammatory bowel disease including Crohn's disease and ulcerative colitis, hepatitis, toxic epidermal necrolysis (TEN), Stevens-Johnson syndrome, or antiphospholipidsyndrome.
