First-line Furmonertinib in Advanced NSCLC Patients With EGFR Uncommon Mutation

• Status: Recruiting
• Trial end date: 2025-10-31
• Target enrollment: 0
• Participant gender: All

Summary

Furmonertinib, a newly-designed pan-EGFR-TKI with a trifluoroethoxypyridine-based molecule structure, has shown promising clinical efficacy in EGFR Ex19del/L858R/T790M/Ex20ins mutant advanced NSCLC with an acceptable safety profile without new signals from 80mg to 240mg dose level in phase 1-3 clinical trials. Whether EGFR G719X/S768I/L861Q mutation positive advanced NSCLC patients can benefit from first-line furmonertinib 160mg per day has not been reported. This study aims to investigate the efficacy and safety of furmonertinib 160mg per day in EGFR G719X/S768I/L861Q mutant patients under first-line treatment of advanced NSCLC setting.

• Willing to use contraception (male patients); Voluntary and agree to follow the study treatment protocol as well as follow-up plan, and can accept the oral medicine treatment.

Exclusion Criteria:

• small cell lung carcinoma;

• History of hypersensitivity to active or inactive excipients of investigational product (IP) or drugs with a similar chemical structure or class to investigational product (IP);

• Confirmed EGFR Ex20ins or Ex19del or L858R or T790M mutant;

• Patient who receive prior treatment including: any Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKI); the patients who have received intrapleural perfusion therapy can only be enrolled 28 days or more after the pleural effusion is stable; major surgery within 4 weeks of the first dose of investigational product (IP); radiotherapy treatment to more than 30% of the bone marrow or with a wide field of radiation within 4 weeks of the first dose of IP; CYP3A4 strong inhibitor or strong inducer is used within 7 days prior to the first dose, or need to receive these drugs during the study period; traditional Chinese medicine and traditional Chinese medicine preparations with anti-tumor as indications and with adjuvant treatment of tumor is used within 7 days prior to the first dose, or need to receive these drugs during the study period; patients who are receiving drugs known to prolong QTc interval or may cause torsade de pointe and need to continue to receive these drugs during the study period; the time from the treatment with any other investigational product or its analogue to the first dose does not exceed 5 half-lives of the drug or 14 days, whichever is longer.

• Prior treatment with any systemic anti-cancer therapy for advanced Non-Small Cell Lung Cancer (NSCLC) including chemotherapy, biologic therapy, target therapy, immunotherapy, or any investigational drug, except neoadjuvant or adjuvant therapy before 6 months prior to the first dose IP;

• At the beginning of study treatment, any unresolved toxic reaction to prior treatment is present, which exceeds Grade 1 in accordance with Common Terminology Criteria for Adverse Events (CTCAE) (except for alopecia), and exceeds Grade 2 for prior platinum treatment-related neuropathy;

• Refractory nausea and vomiting, chronic gastrointestinal diseases, inability to swallow the formulated product, or previous significant bowel resection that would preclude adequate absorption of IP;

• Any evidence of severe or uncontrolled systemic diseases, including uncontrolled hypertension, active bleeding diatheses, and active infection, which in the Investigator's opinion makes it undesirable for the patient to participate in the trial;
