General information
Database:DB00078
Objective:To investigate efficacy and safety of sorafenib in patients with advanced lung adenocarcinoma as second or thirdline treatment after failure of epidermal growth factor receptor tyrosine kinase inhibitors (EGFRTKIs) therapy
Authors:Zhou Q, et al
Title:A multicenterphase II study of sorafenib monotherapy in clinically selected patients with advanced lung adenocarcinoma after failure of EGFRTKI therapy (Chinese Thoracic Oncology Group, CTONG 0805).
Journal:Lung Cancer
Year:2014
PMID:24440279
Trial Design
Clinical Trial Id:NCT00922584
Agent:sorafenib
Target:Vascular endothelial growth factor receptor 1
BRaf protooncogene serine/threonineprotein kinase
Protooncogene tyrosineprotein kinase receptor ret
Cancer Type:lung cancer
Cancer Subtype:advanced lung adenocarcinoma
Therapy Type:mono
Therapeutic Combination Type:NA
Therapeutic Combination Content:NA
Study Type:A multicenterphase II study of sorafenib monotherapy (Chinese Thoracic Oncology Group, CTONG 0805)
Key Patients Feature:Patients who were diagnosed with stage IIIB or stage IV lung adenocarcinoma, and benefited from one prior EGFRTKI therapy and then failed
Biomarker:genotype of Bcl2interacting mediator of cell death (BIM) deletion polymorphism and EGFR mutation status
Biomark Analysis:In 30 tumor tissues, 22 EGFR active mutations were found. The DCR had no significant difference between mutationpositive and wildtype patients (31.8% vs. 42.9%, respectively; HR, 0.622; p=0.665).
Control Group Info:single arm
Treatment Info:Patients received oral sorafenib 400mg twice daily continuously until disease progression or intolerable toxicity.
Primary End Point:disease control rate (DCR).
Secondary End Point:safety, progression free survival (PFS) and overall survival (OS).
Patients Number:64
Trial Results
DLT_MTD:Patients received oral sorafenib 400mg twice daily continuously until disease progression or intolerable toxicity.
Objective Response Rate:NA
Disease Control Rate:32.8%, which did not meet the predefined statistical hypothesis of 38.4%
Median Time to Progression:NA
Median PFS A vs. C:3.7 months [95% (confidence interval), 3.53.9 months]
Median OS A vs. C:7.4 months (95% CI, 5.79.2 months)
Adverse Event(agent arm):Handfoot syndrome (HFS) was the predominant toxicity occurring in 71.9% of patients. Fourteen patients (21.9%) had more than and equal to grade 2 dermatologic reactions that resulted sorafenib dose reduction in three patients (4.7%).
Conclusions:Sorafenib monotherapy did not achieve positive result in patients defined in our trial and they need better biomarker to determine the population who can benefit from sorafenib treatment
