Критерии участия

Критерии включения

• Male or female aged ≥18 years.
• Patients with advanced solid tumors (including but not limited to urothelial carcinoma, breast cancer, non-small cell lung cancer, ovarian cancer, endometrial cancer, and cervical cancer) that have been histologically or cytologically confirmed as having failed/cannot tolerate/have no standard treatment/are currently unsuitable for standard treatment.

• Received any P-glycoprotein (P-gp) inducer/inhibitor, strong CYP3A inhibitor, or breast cancer resistance protein (BCRP) inhibitor within 14 days prior to first administration (see Appendix 3 for the exclusion list).
• Patients who received chemotherapy within 3 weeks or radiotherapy, biotherapy, endocrine therapy, targeted therapy, immunotherapy, or other anti-tumor treatments within 4 weeks prior to first administration of the study drug, excluding the following.
• Patients who received systemic glucocorticoid therapy or any other form of immunosuppressive therapy (equivalent to a prednisone dose >10 mg/day) within 2 weeks prior to the first dose.
• Patients whose adverse reactions to previous antitumor therapy have not recovered to a CTCAE 5.0 grade ≤1 or the level specified in the inclusion/exclusion criteria (excluding toxicities deemed safe by the investigator, such as alopecia, grade 2 peripheral neurotoxicity, and stable hypothyroidism after hormone replacement therapy).
• Patients with primary central nervous system (CNS) malignancies, CNS metastases that have failed local treatment, or carcinomatous meningitis; patients with asymptomatic brain metastases, or stable clinical symptoms such as neurological symptoms and who do not require corticosteroids or other treatments targeting brain metastases for ≥4 weeks may be enrolled.
• Patients with uncontrollable pleural effusion, pericardial effusion, or ascites requiring repeated drainage.
• Patients with known interstitial lung disease (ILD) or non-infectious pneumonia, currently symptomatic or requiring prior systemic glucocorticoid therapy, whose toxicity assessment or management is deemed by the investigator to potentially affect the investigational treatment.
• Patients with a history of organ transplantation or allogeneic bone marrow transplantation, or who received autologous stem cell transplantation within 3 months prior to the first dose.
• Patients who underwent major surgery within 4 weeks prior to the first dose or have not yet recovered from surgery.
