      Background

      Ceritinib have shown potent efficacy in both ALK and ROS-1 rearranged NSCLC. However, high rate of treatment interruption was suffered due to gastrointestinal or liver toxicity using Ceritinib 750mg fasting in previous study. Recently, ASCEND-8 study reported an improved tolerance and a trend to better efficacy with 450mg with food, but little data is available in Chinese patients. This first-time real-world study aims to assess the safety profile and preliminary efficacy of Ceritinib 450mg with food in Chinese patients.

      Method

      From Oct 2018 to March 2019, 51 ALK or ROS1 positive NSCLC patients received ceritinib were enrolled from 8 centers in Sichuan province. Safety profile and preliminary efficacy were retrospectively analyzed. The follow-up was to 31st March 2019.

      Result

      The baseline characteristics of enrolled patients are listed in Table 1. The median time from diagnosis to Ceritinib treatment is 15.93 months(Range:1.37- 89.97), the median treatment duration is 2.63 months (Range:0.2-5.73)by the time of data cut off.

      50 out of 51 patients were assessable for toxicity. The adverse event (AE) rate is 76%, majority of which are grade 1/2. Only 2 patients reduced to 300mg due to AE and no patient dead or terminated treatment due to Ceritinib related AEs. Details are in the Table 2. By the data cut-off, 15 patients have stopped treatment due to disease progression(33.3%),death (53.3%) or other reasons(13.3%)。Among the 39 patients underwent radiological assessment,the ORR was 41.0% and DCR was 87.2%。

      Conclusion

      Ceritinib 450mg with food demonstrated a good safety profile and efficacy with lower AE incidence rate and better compliance rate compare to ASCEND-8 data for Chinese patients in real-world setting.

      JCSE01.28 - Changes of Brain Structure in Advanced NSCLC Patients Receiving EGFR-TKIs: Dynamic Analysis Based on Series MRI Images (ID 3865)

      07:00 - 11:15  |  Author(s): Yongsheng Wang

      Abstract
      Background
      EGFR-TKI was the standard care for metastatic NSCLC patients harboring positive EGFR mutation, which might inhibit EGF signaling pathway and consequently have effect on differentiation, maturation and rehabilitation of neural cells. For the first time, we evaluated the dynamic changes of white matter lesion (WML) and gray matter volume (GMV) among such patients based on series of MRI images.

      Methods
      We retrospectively identified 778 patients with pathologically diagnosed advanced NSCLC receiving first-generation EGFR-TKIs in our hospital from 2010 to 2017, and 75 patients without brain metastasis and else comorbidity (hypertension, etc.) were analyzed. The modified Scheltens visual scale were performed to evaluate the changes of WML based on the series (baseline, 12 months' point and 24 months' point) of MRI images, and CBM (cluster-based morphometry) method based on SPM12 were adopted to identify GMV loss. The statistical methods were performed using SPSS software 22.0.

      Results
      During the 24-month EGFR-TKI treatment, the patient's WML visual scores showed a progressive worsen. Comparing to the baseline (6.680±3.636), the scores were significantly changed at the 12 months' point (8.650±3.857; Mean scores increasing 1.973, 95% CI 1.595-2.352, p<0.001) and changed more obviously at the 24 months' point (10.110±3.854; Mean scores increasing 3.427, 95% CI 2.979-3.874, p<0.001), respectively. Also, the significant GMV loss were found in subregions of the right occipital lobe (mean decrease 76.714, 95% CI 40.739-112.690), left occipital lobe (mean decrease 93.476, 95% CI 37.483-149.469) and left basal ganglia (mean decrease 37.571, 95% CI 21.576-53.567), respectively (all p<0.005, the cluster level FDR<0.05).

      Conclusion
      Dynamic structural analysis of series brain MRI images showed the significant worsen of the WML and GMV loss in patients with advanced NSCLC receiving EGFR-TKIs chronically. Perspective studies are warranted to verify its impact on the cognitive deficiency and hypomnesis among these patients in future.

      OA04.03 - A Randomized Phase 3 Study of Camrelizumab plus Chemotherapy as 1<sup>st</sup> Line Therapy for Advanced/Metastatic Non-Squamous Non-Small Cell Lung Cancer (Now Available) (ID 1682)

      15:15 - 16:45  |  Author(s): Yongsheng Wang

      Background

      Platinum-based chemotherapy remains 1st line therapy for advanced non-small cell lung cancer (NSCLC) without oncogenic drivers in China. Camrelizumab (SHR-1210, a potent anti‒PD-1 monoclonal antibody) has shown promising activity in multiple malignancies. Here, we report interim analysis results on efficacy and safety of camrelizumab plus carboplatin/pemetrexed as 1st line treatment in Chinese advanced/metastatic non-squamous NSCLC patients with negative oncogenic drivers.

      Method

      In this open-label, randomized, multicenter phase 3 study (SHR-1210-303), patients with advanced/metastatic, non-squamous NSCLC with negative EGFR or ALK were stratified by sex and smoking history (≥ 400/year versus ˂ 400/year) and were randomly assigned (1:1) to receive 4 to 6 cycles of carboplatin (AUC=5) plus pemetrexed (500 mg/m2) with or without camrelizumab (200 mg), followed by pemetrexed with or without camrelizumab as maintenance therapy up to disease progression or intolerable toxicity. Treatment was given every 3 weeks. Crossover to camrelizumab monotherapy was permitted for patients in the chemotherapy arm who had confirmed disease progression. The primary endpoint was PFS per blinded independent central review according to RECIST v1.1. Secondary endpoints included ORR, DCR, DoR and OS. Data of subgroup analysis will be reported. Clinical Trials.gov number: NCT03134872.

      Result

      Between May 12, 2017 and Jun 6, 2018, 419 patients were randomized, among whom 205 received camrelizumab plus chemotherapy and 207 received chemotherapy treatment. After a median follow-up of 11.9 months, median PFS was 11.3 months (95% CI 9.5‒not reached) in camrelizumab plus chemotherapy arm and 8.3 months (95% CI 6.0‒9.7) in chemotherapy arm (HR 0.61 [95% CI 0.46‒0.80], p=0.0002). ORR, DCR, DoR and OS with camrelizumab plus chemotherapy were superior to chemotherapy (Table 1). Grade 3/4 adverse events occurred in 66.8% of patients in camrelizumab plus chemotherapy arm and 51.2% of patients in chemotherapy arm. There were 5 treatment-related deaths in camrelizumab plus chemotherapy arm and 4 in chemotherapy arm.

      Conclusion

      First-line camrelizumab plus chemotherapy shows substantial clinical benefit in patients with advanced/metastatic non-squamous NSCLC with negative EGFR or ALK in terms of PFS, ORR, and OS and acceptable safety profiles. The combination should become novel standard 1st line therapy for this population.

      Dynamic structural analysis of series brain MRI images showed the significant worsen of the WML and GMV loss in patients with advanced NSCLC receiving EGFR-TKIs chronically. Perspective studies are warranted to verify its impact on the cognitive deficiency and hypomnesis among these patients in future.
