3. Major surgery (e.g., intra-thoracic, intra-abdominal or intra-pelvic) within 4 weeks prior (2 weeks for resection of brain metastases) to starting PLB1004 or who have not recovered from side effects of such procedure;
4. Thoracic radiotherapy to lung fields ≤ 4 weeks prior to starting PLB1004. For all other anatomic sites (including radiotherapy to thoracic vertebrae and ribs), radiotherapy ≤ 2 weeks prior to starting PLB1004 or patients who have not recovered from radiotherapy-related toxicities. Palliative radiotherapy for bone lesions ≤ 2 weeks prior to starting PLB1004 is allowed;

Exceptions to this exclusion include the following: completely resected basal cell and squamous cell skin cancers, indolent malignancies that currently do not require treatment, and completely resectedcarcinoma in situ of any type;
9. Past medical history of interstitial lung disease, drug-induced interstitial lung disease, radiation pneumonitis which required steroid treatment, or any evidence of clinically active interstitial lung disease;
