Researchers present ongoing HCRN LUN18-335 RAMOSE Study

Xiuning Le, MD, PhD

Hoosier Cancer Research Network investigators presented the ongoing study LUN18-335, RAMOSE: An open-label randomized Phase II study of osimertinib with or without ramucirumab in TKI-naïve EGFR-mutant metastatic non-small cell lung cancer (NSCLC), during the World Conference on Lung Cancer earlier this year.

Led by Xiuning Le, MD, PhD, of the University of Texas MD Anderson Cancer Center, the goal of this multicenter study is to determine the efficacy of the combination of osimertinib and ramucirumab in treatment-naïve EGFR-mutant non-small cell lung cancer. An earlier phase I study demonstrated the safety and feasibility of this combination.

LUN18-335 is a randomized, open-label phase 2 study comparing osimertinib 80mg daily + ramucirumab 10 mg/kg every weeks (O+R) to osimertinib 80mg daily monotherapy (O) for initial treatment of metastatic EGFR-mutant NSCLC. Patients are randomized 2:1 to the O+R versus O groups, with stratification based on type of EGFR mutation and presence of central nervous system metastasis. The trial will enroll a total of 150 patients, allocating 100 to O+R and 50 to O monotherapy. The primary endpoint is progression-free survival.

At the time the abstract was published, 29 patients had been accrued: 17 subjects randomized to the O+R arm and 8 to the O arm. Early analysis from the RAMOSE trial shows no unexpected signals of toxicity with the combination of O+R. Enrollment for the trial is ongoing.
