About this study
Official title: A Randomized, Controlled Phase III Trial to Evaluate the Efficacy of Elortinib vs Gefitinib in Advanced Non-small-cell Lung Cancer With EGFR Exon 19 or 21 Mutations
This is a randomized controlled trial to compare efficacy and safety between erlotinib and gefitinib in advanced NSCLC harboring EGFR exon 19 or 21 mutations.Eligible patients were randomized to receive erlotinib or gefitinib in any line settings.The primary endpoint was progression-free survival (PFS).
Read the detailed description
Patients with stage IV NSCLC who have EGFR exon 19 or 21 mutations will randomized to received oral erlotinib 150mg or gefitinib 250mg once daily until disease progression or unacceptable toxicity. Method of direct DNA sequencing of tumor tissue is used to analysis EGFR mutation status of exons 18-21. The response will be evaluated by RECIST criteria first month,second month and then repeat every 3 months after the beginning of the treatment weeks.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing erlotinib and gefitinib in people with Thoracic Neoplasms, run by Chinese Society of Lung Cancer at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 1 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
progression-free survival (time frame: two years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01024413, which also lists 16 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Mar 2017.
