Abstract Disclosures


Background: In REVEL, adding ramucirumab to docetaxel improved response rates among Pt-treated aNSCLC pts. This observational study evaluated rwTR in aNSCLC pts treated with R+D after Pt & ICI or other (non-ICI) therapies. Methods: Adult aNSCLC pts receiving 2L/3L R+D between 3/1/15 & 6/30/18, after 1L/2L Pt therapy, with ≥ 1 documented rwTR assessment, &≥ 3 months of potential follow-up were selected from the Flatiron Health EHR-derived de-identified database (n = 172). Based on prior ICI exposure, pts were assigned to either the R+D post-ICI or the R+D post non-ICI [other] unmatched cohort. Study endpoints during R+D therapy included real-world (rw) objective response rate [rwORR], rw disease control rate [rwDCR], rw time to first response [rwTTFR], rw duration of response [rwDOR] & rw best response [rwBR]. Results: Overall, median age was 66.0 years and most pts were male (54.7%), white (70.3%), treated in the community (99.4%), had nonsquamous histology (79.7%), were stage IV at diagnosis (70.9%), had a low (≤ 1) Charlson comorbidity index (90.7%) & ECOG ≤ 1 (57.6%). Among tested pts, most were negative for EGFR (93.0%), ALK (94.9%) ROS1 (96.6%), or PD-L1 (75.0%). Baseline characteristics were similar between cohorts. Table shows significant differences in rwBR & rwDCR when stratified by cohort. Conclusions: Pts receiving R+D in the post-ICI setting had improved rwDCR compared to the R+D post-Other group, driven by a greater proportion of rwPR & a higher rate of rwSD as rwBR. The proportion of rwPD as rwBR was lower in R+D post-ICI pts. rwTR rates were generally similar to tumor response outcomes reported in REVEL. Understanding impact on OS is warranted given the increasing use of ICIs in earlier lines of therapy.
