Abstract 2791
Background
ULTIMATE, a phase III trial, showed a significant superiority in terms of progression free survival (PFS) and less toxicity of the combination paclitaxel-bevacizumab versus docetaxel as second or third-line treatment. With the growing role of immunotherapy as first-line setting for advanced non-small cell lung cancer (NSCLC), there is a need to redefine strategies to failure. The use of the paclitaxel-bevacizumab combination could be an option.
Methods
This retrospective study identified patients treated with paclitaxel and bevacizumab according to the ULTIMATE study in 3 centers in France. Main objectives were to describe safety and efficacy of this combination in metastatic non-squamous NSCLC as second-line therapy or beyond, with a particular interest for the sub-group of patients treated just after immune checkpoint inhibitors.
Results
From 1st September 2010 to 1st avril 2018, 76 patients started the paclitaxel-bevacizumab combination : 42 (55%) male, 18 (24%) and 36 (47%) treated in second and third-line respectively, and 22 (29%) in fourth-line or more. Objective response rate (ORR) was 37% (28/76) and disease control rate 74 % (56/76). Median PFS and OS were 5,7 [95%CI: 4,1-6,9] months and 11,2 [95%CI: 8-not reached] months respectively. For patients treated in second and third-line, ORR was respectively 39% and 42%, PFS 4 months [95%CI: 2,5-7,7] and 6 months [95%CI: 4-7], OS 9,4 months [95%CI: 2,7-not reached] and was not reached in third-line at 12 months. Grade 3–4 adverse events included asthenia 5% (4/76), neurotoxicity 3% (2/76), bleeding events 4% (3/76), and hematological toxicity 1% (1/76). Interestingly, in the subgroup of patients treated with immunotherapy just before paclitaxel-bevacizumab (33/76), ORR was 42% (14/33), median PFS was 6,2 [95% CI: 4,6-7,7] months, and median overall survival was not reached at 12 months.
Conclusions
This results exhibited an acceptable toxicity profile and an encouraging efficacy as second-line treatment or beyond for non-squamous NSCLC patients. For patient treated just after immunotherapy the results are very promising.
