(If sufficient wash-out time has not occurred due to the schedule or PK properties of an agent, a longer wash-out period may be required.)
  6. Mean QT interval corrected for heart rate (QTc) 470 ms calculated from 3 electrocardiograms (ECGs) using Frediricia's Correction
  7. Current or prior use of immunosuppressive medication within 28 days before the first dose of durvalumab, with the exceptions of intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid
  8. Any history of hypersensitivity to durvalumab or tremelimumab, FOLFOX or their excipients
  9. Any unresolved toxicity (CTCAE grade >1) from previous anti-cancer therapy. Subjects with irreversible toxicity that is not reasonably expected to be exacerbated by the investigational product may be included (e.g., hearing loss, peripherally neuropathy)
  10. Any prior Grade 3 immune-related adverse event (irAE) while receiving any previous immunotherapy agent, or any unresolved irAE >Grade 1
  11. Active or prior documented autoimmune disease within the past 2 years NOTE: Subjects with vitiligo, Grave's disease, or psoriasis not requiring systemic treatment (within the past 2 years) are not excluded

  17. Sever concurrent disease, or co-morbidity that in the judgment of the investigator, would make the patient inappropriate for enrolment
