Furmonertinib Monotherapy and Combination Therapy in Advanced EGFR Mutant NSCLC With Uncleared ctDNA

• Status: Not yet recruiting
• Trial end date: 2028-02-29
• Target enrollment: 0
• Participant gender: All

Summary

EGFR mutation positive advanced NSCLC patients with uncleared ctDNA have poor prognosis, whether they can benefit from combination therapy has not been reported. This study aims to investigate the efficacy and safety of combination therapy compared with furmonertinib monotherapy in advanced EGFR mutant NSCLC with uncleared circulating tumor cell DNA.

11. Voluntary and agree to follow the study treatment protocol as well as follow-up plan, and can accept the oral medicine treatment;

12. Voluntary and agree to sign the informed consent for genetic research, and provide enough fresh blood samples for central NGS testing.

Exclusion Criteria:

1. squamous cell lung carcinoma;

2. 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);

3. Confirmed EGFR 20 exon insertion mutations at any time after the initial diagnosis;

4. Patient who receive prior treatment including any of the following:

• 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;

5. Prior treatment with any systemic anti-cancer therapy for advanced Non-Small Cell Lung Cancer (NSCLC) not amenable to curative surgery or radiation including chemotherapy, biologic therapy, target therapy, immunotherapy, or any investigational drug, except neoadjuvant or adjuvant therapy before 6 months prior to the first dose;

6. 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.

7. Spinal cord compression; symptomatic and unstable brain metastases, except for those patients who have completed definitive therapy, are not on steroids, and have a stable neurological status for at least 2 weeks after completion of the definitive therapy and steroids.

8. Diagnosed other malignant tumors or had a history of other malignant tumors in last 5 years, except for skin basal cell carcinoma, cervical carcinoma in situ and breast ductal carcinoma in situ which have been effectively controlled;

9. Recent active digestive diseases such as duodenal ulcer, ulcerative colitis, ileitis, intestinal perforation, intestinal fistula, or other conditions that may cause gastrointestinal bleeding or perforation as the researchers may prescribe. Or 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;

10. 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;

11. Past medical history of Interstitial Lung Disease (ILD), drug-induced Interstitial Lung Disease, radiation pneumonitis that required steroid treatment, or any evidence of clinically active Interstitial Lung Disease;

12. Any evidence of known corneal injury;
