Within 28 days before the first study treatment, subjects received external beam radiotherapy, with the exception of palliative radiotherapy. Within two weeks before the first study treatment, subjects had received traditional Chinese medicine therapies with anti-tumor indications.
Subjects who have experienced Grade 4 myelosuppression following prior anti-tumor therapy, or Grade 3 myelosuppression requiring more than six weeks for recovery, or who have received external radiotherapy targeting extensive bone marrow (> 25%) in the past are ineligible. Within 28 days prior to the first study treatment, subjects must not have received blood transfusion therapy. -
The subjects' prior anti-tumor treatment toxicity had not resolved to CTCAE grade ≤1 (NCI CTCAE v5.0), with the exception of alopecia (all grades permitted) and peripheral neuropathy (requiring recovery to grade ≤2).
