Objectives of Study:

1. Primary Objective:To evaluate the median progression-free survival (mPFS) in patients with EGFR-positive oligometastatic tumors treated with vibecotamab in combination with SBRT of oligometastatic lesions and investigator’s choice of systemic therapy, in order to define the core value of the combination regimen in improving patient prognosis. 2. Secondary Objectives:To evaluate the overall survival (OS), objective response rate (ORR), disease control rate (DCR), and duration of response (DOR) in patients with EGFR-positive oligometastatic tumors treated with vibecotamab plus SBRT of oligometastatic lesions and investigator's choice of systemic therapy; To assess the safety and tolerability of vibecotamab in combination with SBRT of oligometastatic lesions and investigator's choice of systemic therapy. 3. Exploratory Objectives:To explore the correlation between EGFR expression levels and clinical response/survival outcomes, aiming to identify potential populations that derive the most benefit (advantageous benefit populations).
