Afatinib in Lung Cancer With EGFR Mutation From Circulating Tumor DNA

Study Overview
=================
Brief Summary
-----------------
Treatment efficacy of afatinib will be assessed in patients with lung cancer harboring EGFR mutations which were detected from circulating tumor DNA.

Detailed Description
-----------------
Obtaining Tumor tissue or cytology samples are not always available in some patients with lung cancer. Recently, studies showed that circulating tumor DNA can be used as a suitable substitute for mutation analysis. The sensitivity of EGFR mutation tests using circulating tumor DNA was reported in the range of 65.7% (10) to 75% (11), with high specificity and positive predictive value. In this trial, treatment efficacy of afatinib will be assessed in patients with NSCLC harboring EGFR mutations which were detected from circulating tumor DNA.

Official Title
-----------------
A Phase II, Open-Label, Multicentre Study to Assess the Anti-tumour Activity of Afatinib in Patients With Activating Epidermal Growth Factor Receptor Mutation in Circulating Tumor DNA

Conditions
-----------------
Lung Neoplasms, EGFR Gene Mutation

Intervention / Treatment
-----------------
* Drug: Afatinib

Activating EGFR mutation (G719X, exon 19 deletion, L858R, L861Q) detected from circulating DNA Any one of the following criteria should be met Unavailable or failed pathologic/cytologic diagnosis Wild type or failed EGFR testing based on tumor tissue No more tumor sample available for EGFR test Measurable lesion by RECIST v1.1 Females should be using adequate contraceptive measures, should not be breast feeding and must have a negative pregnancy test prior to start of dosing or evidence of non-child bearing potential. Male patients should be willing to use barrier contraception. Provision of signed and dated, written informed consent prior to any study specific procedures, sampling and analyses Adequate organ function, defined as all of the following: Absolute neutrophil count (ANC) >=1500/mm3 Platelet count >= 75,000 /mm3 Serum creatinine < 1.4 mg/dL AST or ALT < three times the upper limit of normal Exclusion Criteria: Prior exposure to EGFR-TKI. Prior chemotherapy will be permitted. Previous or concomitant malignancies at other sites, except effectively treated non-melanoma skin cancers, carcinoma in situ of the cervix, ductal carcinoma in situ or effectively treated malignancy that has been in remission for more than 3 years and is considered to be cured. Severe or unstable medical conditions such as history or presence of clinically relevant cardiovascular abnormalities such as uncontrolled hypertension, congestive heart failure NYHA classification of ≥ 3, unstable angina or poorly controlled arrhythmia as determined by the investigator. Myocardial infarction within 6 months prior to randomisation.
