About this study

Official title: A Single-Arm, Multicenter, Phase II Clinical Trial of Firmonertinib in Combination With Definitive Radiotherapy for Patients With Stage III Unresectable Pulmonary Adenocarcinoma Harboring Positive EGFR Uncommon Driver Mutations

This is a prospective, single-arm, Phase II clinical study aimed at evaluating the efficacy and safety of 160mg fimonertinib in combination with definitive radiotherapy for patients with EGFR uncommon driver mutation-positive, Stage III unresectable lung adenocarcinoma. The primary endpoint is Progression-Free Survival (PFS), assessed by the investigator according to RECIST 1.1 criteria, defined as the time from the first dose to objective disease progression or death (from any cause). Secondary endpoints include PFS by different mutation types, OS, ORR, DCR, as well as adverse events and their severity.

Read the detailed description

The standard treatment for patients with unresectable Stage III non-small cell lung cancer (NSCLC) is definitive concurrent chemoradiotherapy followed by consolidative immunotherapy with durvalumab. However, the efficacy of this approach remains limited. For EGFR-mutant patients, the benefit of immunotherapy is modest, highlighting the need for alternative strategies. Although the third-generation EGFR-TKI firmonertinib has become a standard first-line therapy for advanced NSCLC harboring common EGFR mutations (exon 19 deletions and L858R), patients with uncommon EGFR mutations (e.g., G719X, S768I, L861Q, and various exon 20 insertion mutations) represent a heterogeneous and understudied population. For most of these uncommon mutations, no approved targeted therapy currently exists in the setting of Stage III unresectable NSCLC.

Firmonertinib is a novel, brain-penetrant third-generation EGFR-TKI that selectively and irreversibly inhibits both EGFR-sensitizing and T790M resistance mutations. It has demonstrated significant efficacy and a manageable safety profile in patients with EGFR T790M-mutant advanced NSCLC, and has also shown promising results in the first-line treatment of common EGFR mutations. Preclinical and clinical evidence suggests that combining EGFR-TKIs with radiotherapy may yield synergistic effects. Radiotherapy induces DNA damage and alters the tumor microenvironment, potentially enhancing both local and systemic efficacy of targeted agents. This combination strategy could be superior to sequential therapy or radiotherapy alone, particularly in molecularly selected populations. This study aims to explore the potential of this targeted-radiotherapy combination as a novel, chemotherapy-sparing, curative-intent treatment paradigm for patients with Stage III, EGFR uncommon mutation-positive lung adenocarcinoma.

This is an exploratory, Phase II, single-arm study. Enrolled patients will receive the study intervention consisting of oral firmonertinib (160 mg once daily) administered continuously until disease progression, unacceptable toxicity, or other treatment discontinuation criteria are met, concurrently with definitive radiotherapy. Radiotherapy will be delivered using intensity-modulated radiotherapy (IMRT) or volumetric modulated arc therapy (VMAT) to a total dose of 60 Gy in 30 fractions over approximately 6 weeks, with strict adherence to standard organ-at-risk dose constraints and institutional quality-assurance protocols. The primary objective is to evaluate progression-free survival (PFS). Secondary objectives include overall survival (OS), objective response rate (ORR), disease control rate (DCR), safety, and exploratory analyses within specific mutation subgroups.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Firmonertinib and Definitive Thoracic Radiotherapy in people with NSCLC (Non-small Cell Lung Carcinoma) and Stage III, run by Hunan Cancer Hospital 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 14 inclusion and 31 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 8 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 Huai Liu (0731-89762321, liuhuai@hnca.org.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Progression-Free Survival (time frame: From enrollment until 30 months after the completion of treatment). 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 8 Jul 2026.
