• \. Prior use of the following drugs or therapies before the first dose:
• Having received chemotherapy, immunotherapy or other anti-tumor therapy or other investigational drug within 21 days prior to the first dose, or having received oral fluorouracil, small-molecule targeted drugs or Chinese herbal products for antitumor indications within 14 days prior to the first dose;
• Major surgery, radiation therapy (with the exception of palliative radiation to a localized bone or brain lesion, which may be completed up to 14 days prior), or any other minor surgical procedure, excluding placement of vascular access devices, within 28 days prior to the first dose; and any biopsy or other minor procedure within 7 days prior to the first dose.
• In the combination therapy phase, patients who have received systemic treatment with corticosteroids (more than 10 mg/day prednisone or equivalent) or other immunosuppressants within 2 weeks prior to the first dose are allowed to use inhaled or topical steroids or systemic prednisone ≤10 mg/day and equivalent drug product;
