MA07.05 - Immune Checkpoint Inhibitor (ICPi) Re-Challenge: Outcomes Analysis in a French National Cohort of Non-Small-Cell Lung Cancer (NSCLC) Patients (Now Available) (ID 1903)
13:30 - 15:00 | Author(s): Florian Guisier
- Abstract
- Presentation
Background
Anti-PD1/PDL1 deeply changed the NSCLC therapeutic algorithm in the past few years. Unfortunately, a majority of patients experiences disease progression. ICPis re-challenge could be an attractive option but no data supporting this strategy are available. Here we report outcomes of a large cohort of NSCLC patients treated with anti-PD1/PDL1 re-challenge.
Method
We retrospectively collected data about 144 advanced NSCLC patients (diagnosis between 2010 and 2018) from 26 French centers. Patients were re-challenged with ICPis after at least 12 weeks of discontinuation for toxicity, disease progression or clinical decision. Progression Free Survival (PFS) and Overall Survival (OS) were calculated from the start of first or second ICPi to disease progression (PFS1;PFSR) and death or last follow-up (OS1;OS2) respectively.
Result
Median age was 63 year [39 –83], most of patients were male (67%), smokers (87%), adenocarcinomas (62%) and stage IV at diagnosis (66%). Most of patients received the first ICPi round in first or second line (66%) and the second ICPi round in third line or later (79%). In both settings patients received preferentially an anti-PD1 (87%) and no differences were detected regarding brain metastasis or ECOG PS (P = 1.10-1 and P = 1.10-1 respectively). The Best Response during the re-challenge was not associated to that one achieved to the first ICPi (P = 1.10-1). The median PFS1 and PFSR were 13 months [95% CI 10-16.5] and 4.4 months [95% CI 3-6.5] respectively. PFSR was longer in patients discontinued because of clinical decision (6.5 months [95% CI 2.5-11.9]) or toxicity (5.8 months [95%CI 3.5-18]) compared to disease progression (2.9 months [95% CI 2.0-4.4]) (P = 2.10-2) and in those not receiving chemotherapy between the two ICPis (5.8 months [95%CI 4.1-10.5]) compared to those who did (3.0 months [95% CI 2.0-4.4])(P = 2.10-3). Median OS1 was 3.3 years [95% CI 2.9-3.9] without differences according to the discontinuation reason (P =2.10-1). Median OS2 was 1.5 y [95%CI 1.0-2.1] and was longer in patients discontinuing the first ICPi due to toxicity (2.1y [95%CI 1.4-NR]) compared to disease progression (1.0y [95%CI 0.4-1.5]) or clinical decision (1.5y [95%CI 0.4-NR]) (P = 3.10-2). Neither OS1 nor OS2 were affected by treatments received between the two ICPis (P = 3.10-1 and P = 1.10-1 respectively).
Conclusion
ICPis re-challenge might be a useful option mainly in patients discontinuing the first ICPi because of toxicity or clinical decision and in those able to keep a treatment-free period between the two ICPis.

MA14.06 - Nintedanib-Docetaxel in 2nd Line Treatment in No Squamous Non-Small Cell Lung Cancer Patients, Refractory to First Line Treatment (GFPC02-15) (Now Available) (ID 558)
15:45 - 17:15 | Author(s): Florian Guisier
- Abstract
- Presentation
Background
Second line chemotherapy used in advanced Non Small Cell Lung Cancer (NSCLC) have demonstrated a slight survival benefit in patient refractory to a first line platinum based doublet chemotherapy. In exploratory analysis, Nintedanib in combination with docetaxel have shown interesting result in second line setting for refractory NSCLC patients.
Objective: To assess the efficacy in terms of progression-free survival (PFS) of the nintedanib - docetaxel combination in second-line treatment in refractory no squamous NSCLC (NsqNSCL) patients
Method
This prospective, multicentric open-label phase II trial, included patients with advanced Nsq NSCLC (EGFR, ALK wild-type), PS 0-1, progressing during the first four cycles of cisplatin-based induction chemotherapy. Patients received Nintedanib (200 mg X2 /d d2-d20)- Docetaxel (75 mg/m2 d1-d21) combination until progressive disease or unacceptable toxicity.
The primary endpoint was the PFS rate at 12 weeks. Secondary endpoints included median PFS, median overall survival (OS), overall response rate (ORR) and tolerability. Based on a A’Hern’s single-stage phase II design trial (sample size determination is based on exact binomial distribution), the Nintedanib-Docetaxel strategy will be rejected if the primary endpoint was below 22/53 patients at the end of study.
Result
The analysis included 53 evaluable patients managed in 21 centers; last patient included at the end of January 2019. Mean age 58.4 years, male 73 %, adenocarcinoma 97.5%, current/former smokers: 42/50 %, PS 0/1: 25%/75%; weight loss >5% : 19%, stage IV: 100% (38% with brain metastasis, median metastasis 2). All patients received for induction chemotherapy, a platin doublet (22% with bevacizumab), number of cycle 1-2/ 3-4: 57%/ 43%.
Interim analysis reviewed by the independent committee conducted as planned, after the 27 first inclusions concluded that there was no sign of unexpected toxicity (adverse events grade 3-4 :22%, grade 5 :0%) or futility (9 patients meet primary end point on 25 evaluable). The results of the final analysis on the whole population (PFS at 12 weeks (primary end point), median PFS, median OS and toxicity) will be presented at the meeting

P2.14-65 - Efficacy of Dabrafenib Plus Trametinib Combination in Patients with BRAF V600E–Mutant NSCLC in Real World Setting (ID 307)
10:15 - 18:15 | Author(s): Florian Guisier
- Abstract
Background
Dabrafenib plus trametinib (D-T) combination is approved in Europe Union for BRAFV600E–mutant metastatic non-small cell lung cancer(NSCLC) but there is few published data’s on this efficacy and tolerance outside clinical trail results.
Objective: to assess efficacy and tolerance of D-T in real world setting.
Method
Retrospective, multicentric study including BRAF V600E-positive advanced NSCLC receiving D-T outside a clinical trial. Overall survival (OS) and progression free survival (PFS) were analyzed in all population and according lines of D-T treatment (first line treatment or subsequent line treatments).
Result
the analysis included 40 BRAF V600E advanced NSCLC patients managed in 14 centers; at diagnosis: mean age 71 ±9.6 years , female 55 %, adenocarcinoma 95 %, currents/formers smokers 17.5%/50 %, At D-T initiation: PS 0-1/2 or+: 86.8%/13.2% , loss weight> 5%: 24%, symptomatic disease: 92%, stage IV: 95% , mean metastatic site: 2.3 (main metastatic sites: pleura: 46%, bone: 33%, respectively).Mean line of treatment before D-T: 1.5. D-T was a first line treatment in 22.5 %, second line or more 77.5% (25% received one BRAF TKI before). Median time between diagnosis and D-T treatment was 0.7 [95%CI: 0.2-1.3] months in first line setting and 17.3 [95%CI: 10.8-27.2] months.
At the time of analysis 67.5% patients were in treatment with D-T and median follow up since beginning of D-T treatment was 8.7[95%CI: 5-12]months in whole population [7,5, 95%CI: 1-12.3]months for patients treated in first line). D-T dose was modified for 32.5.0% of the patients and definitively discontinued for 12,5 % because of severe adverse events.
Median PFS and OS were not reach and follow up is continued.
The mature results of PFS and OS (whole population and subgroups) will be showed to the WLCC meeting.
