EP1.01-62 - The Safety Profile and Preliminary Efficacy of Ceritinib 450mg with Food in Chinese ALK/ROS-1 Positive NSCLC Patients (Now Available) (ID 1881)
08:00 - 18:00 | Author(s): Meijuan Huang
- Abstract
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): Meijuan Huang
- Abstract
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.
