    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.

  • 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.
