      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

      OA15.02 - Carboplatin-Etoposide Versus Topotecan as Second-Line Treatment for Sensitive Relapsed Small-Cell Lung Cancer: Phase 3 Trial (Now Available) (ID 546)

      14:30 - 16:00  |  Author(s): Jean Bernard Auliac

      Background

      Topotecan is currently the only drug approved in Europe in second line setting for small-cell lung cancer (SCLC). This study investigates whether the doublet carboplatin-Etoposide was superior to topotecan monotherapy as second-line treatment in patients with sensitive relapsed SCLC.

      Method

      this open-label, multicenter, phase 3 trial randomized patients with SCLC that responded to first-line platin etoposide doublet treatment but showed evidence of disease relapse or progression at least 90 days after completion of the first-line treatment. Enrolled patients were randomly assigned (1:1) to receive combination chemotherapy (Six cycles of 3-weeks Carboplatin, AUC 5, day 1 and Etoposide 100 mg/Sqm/d 1-3, intra-venous) or oral Topotecan (2.3 mg/Sqm/d 1-5, every 3 weeks). Primary endpoint was progression free survival (PFS). Secondary endpoints were overall survival (OS), objective response rate (ORR), quality of life and tolerance in the intention-to-treat population, (clinical trialgouv: NCT02738346)

      Result

      178 patients were screened and 164 randomized in 36 centers, with 82 assigned to each treatment group (age: 64.5 ± 7.2 years, men: 72.8%, PS 0/1/>1: 34.7%/56.3%/ 9%. Median PFS was significantly longer in combination chemotherapy group (4.7 months, 95% CI: 3.9-5.5) compare to topotecan group (2.7 months, 95% CI: 2.3-3.2), HR: 0.6, 95% CI 0.4-0.8, p < 0.002. The ORR were significantly more important in the combination chemotherapy than in topotecan arm (ORR 49 % vs 25 %, p < 0,002), but without difference in term of median OS, 7.5 months (95% CI: 5.4-8.7) in combination chemotherapy group versus 7.4 months (95% CI.6.0-9.3) in topotecan arm. Grade 3/4 neutropenia were significantly more common in the topotecan group than in the combination chemotherapy group (35.8% vs 19.7 %, p < 0.001. There is a non-significant trend for more febrile neutropenia in topotecan arm compare to combination arm (13.6 % 6.2 %, p = 0.19, and no difference for grade 3/4 thrombopenia, 35.8 % vs 30.9 %, and anemia, 24.6 % vs 21 %, for topotecan and combination arms, respectively. Two treatment-related deaths occurred in the topotecan arm (febrile neutropenia with sepsis), none in the combination arm. Results of quality of life outcomes will be presented at the meeting.

      Conclusion

      platin - etoposide re-challenge can be considered as a standard second-line chemotherapy for sensitive relapsed SCLC.

      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  |  Presenting Author(s): Jean Bernard Auliac

      • Abstract
      • Slides

      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.
