Apatinib Combine With Platinum-Based Doublet Chemotherapy for First-line Treatment of Advanced NSCLC

Apatinib, an oral highly potent tyrosine-kinase inhibitor targeting VEGFR-2, has demonstrated improved survival in previously treated patients with advanced non-small-cell lung cancer(NSCLC). The phase I study is conducted to explore the safety, tolerability, dose-limiting toxicities(DLT), Maximum Tolerable Dose(MTD), and preliminary anti-tumor activity of Apatinib combined with platinum-based doublet chemotherapy(PB-DC) in first-line advanced EGFR wild type non-squamous non-small cell lung cancer. This will use a dose reduction trial design. A cohort of 3\~6 subjects will be enrolled at each dose level, If 0 of 3 or ≤ 1 of 6 subjects experience a DLT, the phase I trial will stop and the current dose will be considered the MTD. If 1 of 6 or more subjects experiences a DLT, dose reduce to the next dose will occur. Following completion of the dose de-escalation trial and determination of MTD, A randomized controlled trial(RCT) including 30 subjects may be enrolled to further evaluate safety, tolerability, and preliminary anti-tumor activity of Apatinib in combination with platinum-based doublet chemotherapy(PB-DC) in the same target population.
