Subgroup analysis in RAISE: a randomized, double-blind phase III study of irinotecan, folinic acid, and 5-fluorouracil (FOLFIRI) plus ramucirumab or placebo in patients with metastatic colorectal carcinoma progression(aEuro)

Original language description

The RAISE phase III trial demonstrated ramucirumab + FOLFIRI improved survival compared with placebo + FOLFIRI for second-line metastatic colorectal carcinoma patients previously treated with first-line bevacizumab, oxaliplatin, and a fluoropyrimidine. Analyses reported here found similar efficacy and safety in patients regardless of KRAS mutational status, time to first-line progression, and age.The RAISE phase III clinical trial demonstrated that ramucirumab + FOLFIRI improved overall survival (OS) [hazard ratio (HR) = 0.844, P = 0.0219] and progression-free survival (PFS) (HR = 0.793, P &lt; 0.0005) compared with placebo + FOLFIRI for second-line metastatic colorectal carcinoma (mCRC) patients previously treated with first-line bevacizumab, oxaliplatin, and a fluoropyrimidine. Since some patient or disease characteristics could be associated with differential efficacy or safety, prespecified subgroup analyses were undertaken. This report focuses on three of the most relevant ones: KRAS status (wild-type versus mutant), age (&lt; 65 versus &gt;= 65 years), and time to progression (TTP) on first-line therapy (&lt; 6 versus &gt;= 6 months). OS and PFS were evaluated by the Kaplan-Meier analysis, with HR determined by the Cox proportional hazards model. Treatment-by-subgroup interaction was tested to determine whether treatment effect was consistent between subgroup pairs. Patients with both wild-type and mutant KRAS benefited from ramucirumab + FOLFIRI treatment over placebo + FOLFIRI (interaction P = 0.526); although numerically, wild-type KRAS patients benefited more (wild-type KRAS: median OS = 14.4 versus 11.9 months, HR = 0.82, P = 0.049; mutant KRAS: median OS = 12.7 versus 11.3 months, HR = 0.89, P = 0.263). Patients with both longer and shorter first-line TTP benefited from ramucirumab (interaction P = 0.9434), although TTP &lt; 6 months was associated with poorer OS (TTP &gt;= 6 months: median OS = 14.3 versus 12.5 months, HR = 0.86, P = 0.061; TTP &lt; 6 months: median OS = 10.4 versus 8.0 months, HR = 0.86, P = 0.276). The subgroups of patients &gt;= 65 versus &lt; 65 years also derived a similar ramucirumab survival benefit (interaction P = 0.9521) (&gt;= 65 years: median OS = 13.8 versus 11.7 months, HR = 0.85, P = 0.156; &lt; 65 years: median OS = 13.1 versus 11.9 months, HR = 0.86, P = 0.098). The safety profile of ramucirumab + FOLFIRI was similar across subgroups. These analyses revealed similar efficacy and safety among patient subgroups with differing KRAS mutation status, longer or shorter first-line TTP, and age. Ramucirumab is a beneficial addition to second-line FOLFIRI treatment for a wide range of patients with mCRC.
