A Clinical Study to Evaluate the Safety and Tolerability of AWT020 in Patients With Advanced Malignancies

received chemotherapy, immunotherapy and other anti-tumor therapy or other investigational drugs within 21 days before the first dose, or received oral fluorouracil, small molecule targeted drugs or Chinese medicines with anti-tumor indications within 14 days before the first dose;

Major surgery or radiotherapy within 28 days before the first dose (palliative radiotherapy for local bone/brain lesions allowed within 14 days before the first dose), coarse needle puncture biopsy or other minor surgery within 7 days before the start of study therapy, excluding placement of vascular infusion devices;

In combination therapy, patients who have been systematically treated with corticosteroids (> 10 mg prednisone per day or equivalent) or other immunosuppressants for more than 1 week within 2 weeks prior to initial administration are allowed to be treated with inhaled or topical steroids or ≤10 mg/ day systemic prednisone and equivalent doses of similar drugs;

There is active central nervous system metastasis. If the patient has received radiotherapy or surgery in the past, imaging examination within 4 weeks before the first medication indicates stable brain metastases without aggravation or new neurological symptoms, hormone therapy has been discontinued 2 weeks before the first medication, and screening is allowed; For meningeal and brainstem metastases, screening is not allowed regardless of treatment.
