Abstract

Background

ULTIMATE, a phase III trial, showed a significant superiority regarding progression free survival (PFS) of the combination paclitaxel-bevacizumab versus docetaxel as second or third line treatment for advanced non-small cell lung cancer (NSCLC). With the increase use of immunotherapy in first-line setting, second line strategies must be redefined. Paclitaxel-bevacizumab combination could be an option.

Methods

The main objectives were to describe safety and efficacy of this combination in metastatic non-squamous NSCLC as second-line therapy or beyond with a special attention paid to the sub-group treated just after immune checkpoint inhibitors. It was a multicentric retrospective study.

Results

This analysis included from 1st September 2010 to 1st april 2018, 76 patients: 42 (55%) male, 18 (24%) and 36 (47%) treated in second and third line respectively, and 22 (29%) in fourth line or more. Overall 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. 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). In the subset of patients treated in third-line or beyond, immediately after immunotherapy (33/76), we note with interest that 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.

Conclusion

This study shows an acceptable toxicity profile associated with encouraging efficacy of the combination paclitaxel-bevacizumab as second-line treatment or beyond for non –squamous NSCLC patients. Moreover, these results seems to be very promising preliminary findings for patients treated just after immunotherapy. AVATAX is ongoing and should collect data from about 200 patients.
