P2.04-025 - Recombinant Human Endostatin and/or Cisplatin in Treatment of Malignant Hydrothorax and Ascites: A Multicenter Randomized Study (ID 5615)
14:30 - 15:45 | Author(s): Y. Cheng
- Abstract
Background:
To evaluate the clinical efficacy and safety of intra-pleural injection of recombinant human endostatin (Endostar) and/or Cisplatin in treatment of malignant hydrothorax and ascites.
Methods:
A total of 317 patients with more than moderate amount of pericardial effusion malignant hydrothorax and ascites were randomly divided into group A (Endostar group, n=105), group B (Cisplatin group, n=104) and group C (Endostar combined Cisplatin, n=108). After puncture and drainage, Endostar, 45 mg per time by intrathoracic injection or 60 mg per time by intraperitoneal injection was performed in Group A. Cisplatin, 40 mg per time by intra-pleural injection on day 1, 4 and 7, was administrated in group B. Group C was administrated with combined therapy of Endostar and Cisplatin.
Results:
A total of 317 patients were included in full analysis set (FAS), and 275 patients were included in per-protocol set (PPS) . There were 298 cases and 273 cases qualified for evaluation on drug efficacy in FAS and PPS respectively. There was a significant difference in ORR among three groups (P＜0.05), and ORR was higher in Group C than that in Groups A and B (P＜0.05 or P＜0.01). Patients without intracavitary treatment history, with hydrothorax, female, without systemic chemotherapy, with initial treatment on effusion, with sufficient drainage, with hemorrhagic effusion and without diagnosis of gastric carcinoma had better outcome in ORR after treatment (P＜0.05 or P＜0.01). In those with hemorrhagic effusion, the ORRs in Groups A and C were significantly higher than that of Group C (P＜0.01). The median TTP was 68.869 d, 44.951 d, 69.030 d in Groups A, B and C, respectively, with a significant difference (P＜0.01), and was shorter in Group B than that in Groups A and C (P＜0.05 or P＜0.01). The proportion of patients with improved QOL and KPS in Group A was higher than that in Groups B and C after third and sixth administration, respectively (P＜0.05 or P＜0.01). The incidence of adverse reactions was lower in Group A than that in Group B (P＜0.01), but no significant difference was shown between Groups B and C (P＞0.05).
Conclusion:
Intra-pleural injection of Endostar is potentially effective in treatment of patients with malignant hydrothorax and ascites, especially those with hemorrhagic effusion. It shows a synergistic effect with Cisplatin in improving the clinical efficacy, TTP and QOL, but without increasing the risk of adverse reactions.

P3.02b-096 - Osimertinib (AZD9291) in Asia-Pacific Patients with T790M Mutation-Positive Advanced NSCLC: Open-Label Phase II Study Results (ID 4282)
14:30 - 15:45 | Author(s): Y. Cheng
- Abstract
Background:
Osimertinib (AZD9291) is an oral, potent, irreversible EGFR-TKI, selective for both EGFR-sensitizing (EGFRm) and T790M resistance mutations. Following positive outcomes from recent Phase I and II trials, osimertinib is now recommended for patients with EGFR T790M mutation-positive advanced non-small cell lung cancer (aNSCLC).
Methods:
AURA17 (NCT02442349) is an open-label, single arm, Phase II study investigating the efficacy and safety of osimertinib in an Asia-Pacific patient population with EGFRm T790M mutation-positive locally advanced or metastatic NSCLC, who had progressed following EGFR-TKI therapy or EGFR-TKI and chemotherapy. T790M-positive status was confirmed via central testing of biopsy samples using the cobas[®] EGFR Mutation Test. Inclusion required measureable disease, performance status (PS) 0/1, and acceptable organ function; asymptomatic brain metastases were allowed. Patients received osimertinib 80 mg once daily until disease progression. The primary endpoint was objective response rate (ORR) according to RECIST 1.1 (by blinded independent central review, BICR). Secondary objectives included disease control rate (DCR), duration of response (DoR), progression-free survival (PFS), overall survival, and safety and tolerability.
Results:
As of 4 March 2016 data cut-off, 171 patients were enrolled, with 166 evaluable for response: median age, 60.0 years; female, 69%; Asian, 98%; never smokers, 78%; PS 0/1, 15%/85%; EGFR Exon 19 and L858R mutations, 64% and 34% patients, respectively; second-/≥third-line, 32%/68%; median treatment exposure, 5.6 months. Confirmed ORR and DCR (95% CI) by BICR were 60% (52, 68) and 88% (82, 92), respectively. DoR and PFS are not calculable as data is immature. Causally-related adverse events (AEs) grade ≥3 were reported in eight (5%) patients. AEs leading to dose interruption or dose reduction occurred in seven (4%) and two (1%) patients, respectively. Six (4%) patients discontinued treatment due to AEs, two (1%) causally-related AEs as assessed by investigator. The most commonly reported AEs (%, [grade ≥3]) were diarrhoea (29%, [0]), rashes and acnes (grouped terms) (20%, [0]), and dry skin (grouped terms) (17%, [1%]). Interstitial lung disease-like events were reported in three (2%) patients.
Conclusion:
AURA17 demonstrated clinical efficacy of osimertinib in Asia-Pacific patients with EGFR T790M mutation-positive aNSCLC, with an ORR of 60% and DCR of 88% that are comparable to global Phase II trials. Osimertinib was well tolerated, with a low frequency of AEs grade ≥3. No new safety signals were seen and the pattern of AEs was consistent with global studies

PL03.05 - BRAIN: A Phase Ⅲ Trial Comparing WBI and Chemotherapy with Icotinib in NSCLC with Brain Metastases Harboring EGFR Mutations (CTONG 1201) (Abstract under Embargo until December 6, 7:00 CET) (ID 4570)
08:35 - 10:25 | Author(s): Y. Cheng
- Abstract
- Presentation
Background:
Non-small cell lung cancer (NSCLC) with brain metastases （M） had a poor prognosis. Whole brain irradiation (WBI) is a standard of care for this critical medical condition. The median survival is only 4-6 months. Small molecule inhibitors of epidermal growth factor receptor (EGFR) including icotinib achieved very successful results in advanced NSCLC with EGFR mutations. There were no prospective randomized clinical trials to explore the efficacy of EGFR tyrosine kinase inhibitors (TKIs) on brain M.
Methods:
Advanced NSCLC with EGFR sensitive mutations and brain M were randomized to WBI plus chemotherapy (chemo) or icotinib. Patients in WBI arm received radiotherapy with 30Gy/3Gy/10 fractions plus concurrent or sequential doublet chemo of 4-6 cycles. Patients in EGFR TKI arm received icotinib 125mg orally tid until disease progression. Icotinib could be continued beyond progression if clinical benefit was observed by the investigator. Crossover to icotinib from WBI could be permitted. Key inclusion criteria were EGFR mutations and radiologically confirmed brain M with at least 3 lesions. The primary endpoint was intracranial progression-free survival (iPFS) by investigator assessments according to RECIST v1.1. The secondary endpoints included objective response rate (ORR), PFS and overall survival (OS). Safety and tolerability were assessed by measuring adverse events （AEs） (CTCAE v4).
Results:
From Dec. 2012 to June 2015, 176 patients from 17 sites were randomized to WBI+Chemo arm (N=91) or icotinib arm (N=85). The baseline clinicopathologic factors were balanced between the two groups. Median age was 58, PS 1 was 87.2%, non-smoker 70.9%, adenocarcinoma 96.8%, symptomatic brain M were 16.5%. Icotinib significantly improved median iPFS compared with WBI+chemo: hazard ratio [HR] 0.56; 95% CI: 0.36-0.90; p=0.014 (10.0 vs 4.8 months). Median PFS was 6.8 vs 3.4 months, (HR 0.44, 95% CI 0.31-0.63, P<0.001). Median OS had no significant difference between the arms (18.0 vs 20.5 months, HR 0.93, 95%CI 0.60-1.44, P=0.734). Intracranial ORR was significantly improved with icotinib than WBI+Chemo (67.1% vs 40.9%; p<0.001); Overall ORR was 55.0% vs 11.1% (P<0.001). Grade ≥3 AEs assessed by the investigators were reported in 8.2% (N=7) of patients treated with icotinib and 26.2% (N=28) treated with WBI+Chemo. Most common causally related AEs in the icotinib arm were increased liver transaminase & rash; in the WBI+Chemo arm were hematologic toxicity.
Conclusion:
Icotinib demonstrated superior iPFS, PFS and ORR over WBI+Chemo in EGFR mutant advanced NSCLC with brain M, and well-tolerated safety profile. Icotinib would be a treatment option for EGFR mutant patients with brain M (NCT01724801).
