Efficacy and Safety of Tislelizumab Combined With Bevacizumab and Albumin Paclitaxel in Lung Adenocarcinoma

Tislelizumab Combined With Bevacizumab and Albumin Paclitaxel in the Treatment of Advanced Lung Adenocarcinoma: a Single-arm, Phase Ⅱ Clinical Trial

The single arm clinical study is to evaluate the efficacy and safety of Tislelizumab combined with Bevacizumab and albumin paclitaxel in the treatment of advanced lung adenocarcinoma. All of the patients were received EGFR-TKI therapy for 1 line and disease progression. The primary endpoint is six months PFS and safety, the seconday endpoint is ORR and one-year OS rate.

Patients who meet the inclusion criteria will receive Tislelizumab combined with Bevacizumab and albumin paclitaxel for 4 cycles. If there is no disease progression, the patient will continue to receive Tislelizumab maintenance therapy, until the disease progresses or death.

Inclusion Criteria:

• lung adenocarcinoma stage Ⅳ(according AJCC 8)
• received EGFR-TKI for 1 line and disease progression
• EGFR T790M negative
• ECOG PS 0-2

Exclusion Criteria:

• histology of mixed NSCLC with squamous cell carcinoma, neuroendocrine carcinoma and small cell carcinoma.
• have received checkpoint inhibitor.
• uncontrolled pleural effusion, pericardial effusion, or ascites after appropriate intervention
