Sunvozertinib Plus Anlotinib as 1L Treatment in EGFR Mutant Advanced NSCLC-RW

Official title

A Perspective Observation Phase II, Single-Arm Study Evaluating the 1st Line Efficacy and Safety of Sunvozertinib Plus Anlotinib in EGFR-Sensitive Mutations Combined With Co-Mutations Locally Advanced or Metastatic NSCLC

Overview

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 EGFR-sensitive mutations and co-mutations in locally advanced or metastatic treatment-naive non-small cell lung cancer.

Detailed description

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 Dec 2027.

Interventions

• Drug sunvozertinib in combination with Anlotinib
  Sunvozertinib 300 mg once daily (QD) with Anlotinib 8mg once daily （QD in Day 1-14），21 days in one cycle.

Primary outcome measures

• Progression-free survival (PFS) [Time frame: Time from first subject dose to study completion, or up to 36 month]

Secondary outcome measures (4)

• Objective Response Rate (ORR) [Time frame: Time from first dose to last dose, or up to 24 month]
• Overall survival (OS) [Time frame: Time from first subject dose to study completion, or up to 36 month]
• Duration of Response (DoR) [Time frame: Time from first subject dose to study completion, or up to 36 month]
• Adverse events (AEs) according to CTCAE 5.0 [Time frame: From first dose until 28 days after the last dose, up to 24 month]

Eligibility criteria

Inclusion criteria

• Understand the requirements and contents of the clinical trial, and provide a signed and dated informed consent form.
• Age ≥ 18 years.
• Histopathology or cytology confirmed and recorded local progression or metastatic non-small cell lung cancer without systemic treatment.
• EGFR-sensitive mutations confirmed by an accredited local laboratory, including exon 19 deletions, exon 21 L858R point mutations, and T790M mutations, combined with co-mutations, including but not limited to TP53, PIK3CA, catenin beta-1 (CTNB1), and retinoblastoma (RB1).
• ECOG 0 - 1.
• Predicted survival ≥ 12 weeks.
• Adequate bone marrow hematopoiesis and organ function
• Presence of measurable lesions according to RECIST 1.1.
• Subjects with stable brain metastases may be included in the study.

Exclusion criteria

• Prior systemic therapy for locally advanced or metastatic disease.
• Subjects who have received any of the following treatments must be excluded:

• Treatment with molecules such as EGFR, VEGFR antibodies within 4 weeks prior to the first dose of study drug.
• Have received radiation within 14 days prior to the first dose or have not recovered from radiation-related toxicity. Chest and extra-brain palliative radiotherapy, stereotactic radiosurgery, and stereotactic body radiotherapy may be performed 7 days prior to the first dose.
• Ongoing (or inability to discontinue) possibly potent CYP1A2, CYP3A inhibitor (1 week), or inducer (2 weeks) drug therapy or herbal supplements within 1-2 weeks prior to the first dose.
• Presence of spinal cord compression or meningeal metastasis.
• History of other malignant tumors within 2 years.
• Adverse events (except alopecia of any degree) of CTCAE > grade 1 due to prior treatment (e.g., adjuvant chemotherapy, radiotherapy, etc.) prior to the first dose.
• 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.
• Subjects with persistent or active infection, including but not limited to hepatitis B (HBV), hepatitis C (HCV), human immunodeficiency virus (HIV) and COVID-19 infection.
• 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.
• Hypersensitivity to the test drug and the ingredients.
• Other conditions assessed by the investigator to be unsuitable for participation in the study.
