15. Known intolerance, hypersensitivity, or contraindication to any components of MDK-703 or checkpoint inhibitors for applicable cohorts.
16. History of other malignancy within 5 years prior to first dose, except for patients who are disease-free for >2 years after treatment with curative intent or who have carcinoma in situ which has been excised.
17. Any serious medical condition (including pre-existing autoimmune disease or inflammatory disorder), laboratory abnormality, psychiatric condition, or any other significant or unstable concurrent medical illness that in the opinion of the Investigator would preclude protocol therapy or would make the subject inappropriate for the study.
