Study to Evaluate Efficacy and Safety of Firmonertinib Compared With Investigator's Choice of EGFR Inhibitor as First-Line Treatment in Participants Who Have Locally Advanced or Metastatic NSCLC With EGFR P-Loop and Alpha C-Helix Compressing (PACC) Uncommon Mutations
What this study is about
Global, Phase 3, randomly assigned, conducted at multiple hospitals, where both patients and doctors know the treatment given study evaluating the effectiveness and safety of firmonertinib at a dose level of 240 mg QD compared to investigator's choice of osimertinib (80 mg QD) or afatinib (40 mg QD) in participants who have locally advanced or metastatic NSCLC with EGFR PACC mutations, and who have not received any prior therapy for advanced disease. Participants will be randomly assigned in a 1:1 ratio to treatment with firmonertinib or osimertinib or afatinib and will take the assigned dose daily.

Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Key Eligibility Criteria:
- Histologically or cytologically documented, locally advanced or metastatic Non-Small Cell Lung Cancer (NSCLC) not amenable to curative surgery or radiotherapy.
- Documented results of the presence of an Epidermal Growth Factor Receptor (EGFR) PACC mutation in tumor tissue or blood from local testing.
- No prior systemic anticancer therapy regimens received for locally advanced or metastatic Non-Small Cell Lung Cancer (NSCLC) including prior treatment with any Epidermal Growth Factor Receptor (EGFR)-targeting agents (e.g., previous (EGFR) TKIs, monoclonal antibodies, or bispecific antibodies).
- Patients who have received prior neo-adjuvant and/or adjuvant chemotherapy, immunotherapy, or chemo radiotherapy for non-metastatic disease must have experienced a treatment free interval of at least 12 months.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
