Sunvozertinib Plus Anlotinib as 1L Treatment in EGFR-Sensitive Mutations Combined With Co-Mutations Advanced NSCLC

This is a Phase II, open-label, single-arm, single-center clinical study to evaluate the preliminary efficacy of sunvozertinib in combination with anlotinib in patients with locally advanced or metastatic primary non-small cell lung cancer with EGFR-sensitive mutations combined with co-mutations. Approximately 52 NSCLC patients with EGFR-sensitive mutations (19del, L858R and T790M) and co-mutations were enrolled and treated with sunvozertinib (300 mg once daily) in combination with anlotinib (8 mg once daily for 2 weeks, followed by a 1-week interruption) until the patients experienced disease progression, intolerable toxicity, or met the criteria for discontinuation of the trial drug. The primary endpoint was investigator-assessed PFS, and secondary endpoints included ORR, DCR, OS, and safety. The study is expected to commence recruitment in mainland China in about April 2024. It is expected that the trial will end in April 2027.

• History of stroke or intracranial hemorrhage within 6 months prior to the first dose.
• The presence of any severe or poorly controlled systemic disease, including poorly controlled hypertension and active bleeding in the judgment of the investigator.

• Heart-related diseases or abnormalities
• Past history of interstitial lung disease, drug-induced interstitial lung disease, radiation pneumonitis requiring steroid therapy or interstitial lung disease with active clinical symptoms, immune pneumonia caused by immunotherapy.
• Refractory nausea and vomiting, chronic gastrointestinal disease, difficulty swallowing drugs, or inability to adequately absorb sunvozertinib or anlotinib due to previous bowel resection.
• Live vaccine was given 2 weeks before the first medication.
• Women who are breastfeeding or pregnant.
