nivolumab plus ramucirumab in patients with recurrent, advanced, metastatic nsclc

Conditions: Non Small Cell Lung Cancer

Summary: the study will enroll patients with prior io therapy (alone or in combination with chemotherapy or in combination with other io agents) regardless of the pd-l1 level, into a non-randomized combination trial, with primary endpoint of disease control rate.

immunotherapeutic treatment with check-point inhibitors has increased survival in patients with advanced non-small cell lung cancer (nsclc) that does not have any mutation to be targeted. however, the concept that tumors evade immune surveillance through a variety of mechanisms, and that activating the immune system can lead to tumor regression in a variety of tumor types has been known for decades. thus, this study combines the effects to blocking 2 different pathways- inhibition of pd-1 pathway and angiogenic pathway via inhibition of vegr signaling to improve survival as blocking each pathway individually has demonstrated a modest increment. there has been no study using nivolumab in combination with a vegfr2 inhibitor, a drug which has both anti-angiogenic and pleotropic immunomodulatory effects and may synergize with the effect of an anti-pd-1 agent, in solid tumors. activating the anti-tumor effects of t cells by utilizing multiple pathways of both nivolumab and ramucirumab is an endeavor which merits investigation. thus, the study investigates the synergistic effect of targeted anti-antitumor activity of immune checkpoint inhibitor nivolumab and immune-suppressive activity of vegf-inhibitor ramicirumab expecting a favorable overall survival in nsclc patients, with the additional benefit of tolerable toxicities.
