Exclusion criteria
3.2 Exclusion criteria:
An active autoimmune disease that requires systemic treatment (i.e., use of disease-relieving drugs, corticosteroids, or immunosuppressive agents) occurred in the previous 2 years. Replacement therapies (such as thyroxine, insulin, or physiological corticosteroid replacement therapy for adrenal or pituitary insufficiency, etc.) are not considered systemic treatments.
Diagnosed with immunodeficiency or receiving systemic steroid therapy or any other form of immunosuppressive therapy within 7 days before the first administration of the experimental treatment. After consultation with the sponsor, the use of physiological doses of corticosteroids may be approved.
Anti-tumor monoclonal antibody (mAb) received within 4 weeks before the first day of the study, or adverse events caused by the drug received 4 weeks before have not yet recovered (ie ≤ grade 1 or reach baseline level).
Have received chemotherapy, targeted small molecule therapy or radiotherapy within 2 weeks before the first day of the study, or the adverse events caused by the previously received drugs have not yet recovered (ie ≤ grade 1 or reach the baseline level). Note: Subjects with ≤ Grade 2 neuropathy or ≤ Grade 2 hair loss are exceptions to this standard and may be eligible to participate in the study. a. If subjects have undergone major surgery, they must fully recover from the toxicity and/or complications caused by the intervention before starting treatment.
Other malignant tumors are known to be progressing or requiring active treatment. Exclude skin basal cell carcinoma, skin squamous cell carcinoma or cervical carcinoma in situ that have received radical treatment.
Active central nervous system (CNS) metastasis and/or cancerous meningitis are known to exist. Subjects who have received brain metastasis therapy can also participate in this study, provided that their condition is stable (no disease progression confirmed by imaging examination at least 4 weeks before the first administration of the trial treatment, and all neurological symptoms have returned to Baseline level), there is no evidence that new or enlarged brain metastases have occurred, and steroid therapy should be discontinued at least 7 days before the first dose of the trial treatment. This exception does not include cancerous meningitis, which should be excluded regardless of whether the clinical condition is stable. Have a history of pneumonia (non-infectious) requiring steroid treatment or are currently suffering from pneumonia (non-infectious).
Active infections requiring systemic treatment.
It is possible to confuse the test results, prevent the subjects from participating in the research in the whole process of medical history or disease evidence, abnormal treatment or laboratory values, or the researcher believes that participating in the research is not in the subjects' best interests.
It is known that there are mental or drug abuse diseases that may affect compliance with the test requirements.
During pregnancy or lactation, or expected to be during the planned trial period (from the beginning of the screening visit to 120 days after the last dose of the study treatment (applicable to the Pembrolizumab group), or until 180 days after the last dose of the study treatment ( Applicable to paclitaxel group)) conceived female subjects, or male subjects whose spouse becomes pregnant.
Known history of human immunodeficiency virus (HIV) (HIV 1/2 antibody) infection.
Known to have active hepatitis B or C. Active hepatitis B is defined as a known positive result of HBsAg and an HBV viral load exceeding 2000 IU/ml (104 copies/ml). Active hepatitis C is defined as a known hepatitis C antibody positive, and the quantitative result of known hepatitis C RNA is higher than the detection limit of the analytical method. Note: HCV RNA (quantitative) and HBsAg testing will be performed during the screening period; if there are results obtained within 3 months before the screening period, it can also be used.
Live vaccines have been vaccinated within 30 days before the planned start date of the study treatment. a. Note: Seasonal influenza vaccines for injection are generally inactivated influenza vaccines and are allowed to be used; but intranasal influenza vaccines (such as FluMist®) are live attenuated vaccines and are not allowed.
