a clinical study of si-b001 combined with docetaxel in the treatment of non-small cell lung adenocarcinoma and lung squamous cell carcinoma

Conditions: Non-small Cell Lung Adenocarcinoma; Squamous Cell Carcinoma of Lung

Summary: main objectives: to evaluate the benefit of si-b001+ docetaxel on overall survival (os) of bidotaxel. to evaluate the benefit of si-b001+ docetaxel over docetaxel's progression-free survival (pfs) based assessment. secondary objectives: to evaluate the investigator-evaluated progression-free survival (pfs) benefit of si-b001+ docetaxel against docetaxel; to evaluate the difference of objective response rate (orr), disease control rate (dcr) and duration of response (dor) between si-b001+ docetaxel and bidocetaxel. to evaluate the type, frequency and severity of adverse events (teae) and drug-related adverse events (trae) during treatment with si-b001+ docetaxel in comparison with docetaxel. the pharmacokinetic (pk) characteristics of si-b001 will be evaluated. the immunogenicity of si-b001 will be evaluated. subject quality of life.
