PD-L1 and Other Immuno-markers Influenced by Osimertinib Treatment in Advanced NSCLC Patients
- Conditions
- Small Cell Lung Cancer, Polygonal Type
- Registration Number
- NCT03029858
- Lead Sponsor
- Guangdong Association of Clinical Trials
- Brief Summary
The study will investigate whether PD-L1 and other immuno-markers will be influenced by osimertinib treatment in advanced epidermal growth factor receptor (EGFR)T790M positive advanced NSCLC patients. In addition, we will explore whether PD-L1 and other immuno-markers can predict the safety and efficacy of subsequent use of immune checkpoint inhibitors at the time of PD due to osimertinib resistance.

- All
- Target Recruitment
- 155
- The patient enrolled in ASTRIS or patient who are eligible for the ASTRIS study.
- The patient is willing to provide informed consent form to provide specimen before osimertinib treatment and at the time of PD.
- Patients must be able to undergo a fresh tumor biopsy during screening or to provide an available tumor sample taken <2 months prior to screening.
- Fine needle aspirate specimens are not acceptable.
- Specimens from metastatic bone lesions are typically unacceptable unless there is confirmed soft tissue component.
- The tumor specimen submitted to establish eligibility should be of sufficient quantity to allow for PD-L1 IHC and other biomarker analyses (if applicable) and is preferred in formalin-fixed paraffin embedded blocks.
- The patient does not have sufficient tumor tissue specimen available for detection.
- The Patient who is unwilling to use the existing data from medical practice for scientific research.
- The patient who received immunotherapy therapy before.
