About this study

Official title: A Randomized, Open-label, Multi-center, Phase III Clinical Study Comparing SYS6010 With Platinum-based Chemotherapy in the Treatment of EGFR-mutated Locally Advanced or Metastatic Non-small Cell Lung Cancer After Failure of EGFR TKI Treatment

To evaluate the efficacy and safety of SYS6010 versus platinum-based chemotherapy in participants with EGFR-mutated locally advanced or metastatic non-small cell lung cancer (NSCLC)

Read the detailed description

This is a randomized, open-label, multi-center, phase III clinical study, aiming to evaluate the efficacy and safety of SYS6010 versus platinum-based chemotherapy in participants with EGFR-mutated locally advanced or metastatic NSCLC who have failed EGFR TKI therapy.

This study implemented a hierarchical testing strategy to control the overall Type I error at a one-sided alpha level of 0.025. If the null hypothesis for PFS was rejected, the full alpha (0.025) was recycled for OS analysis.

Being tested
SYS6010, Pemetrexed, Cisplatin, Carboplatin

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing SYS6010, Pemetrexed and Cisplatin in people with EGFR-mutated Locally Advanced or Metastatic NSCLC, run by CSPC Megalith Biopharmaceutical Co.,Ltd. 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 10 inclusion and 27 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: looking for participants now, as of the sponsor's last update on 1 Jul 2026. 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?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Clinical Trials Information Group officer (86-0311-69085587, ctr-contact@cspc.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression-free survival (PFS) assessed by independent review committee (IRC) (time frame: Up to approximately 1.5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 Jul 2026.
