The goal of this clinical trial is to learn if the combination therapy with SKB264 and anlotinib works to treat EGFR-TKI-resistant, liver-metastatic non-squamous non-small cell lung cancer (NSCLC). It will also learn about the safety of the combination therapy with SKB264 and anlotinib. The main questions it aims to answer are:
Does combination therapy with SKB264 and anlotinib increase response rate and disease control rate, prolong duation of response and progressioin-free survival.
What medical problems do participants have when taking combination therapy with SKB264 and anlotinib? Researchers will compare combination therapy with SKB264 and anlotinib to a historical data (the response rate of other drugs reported in literature) to see if combination therapy with SKB264 and anlotinib works better to treat EGFR-TKI-resistant, liver-metastatic non-squamous non-small cell lung cancer (NSCLC).
Participants will:
1. receive SKB264 4 mg/kg intravenously on a 14-day cycle, and take anti-H1/H2 antihistamines, acetaminophen, and dexamethasone is recommended before infusion for the first 4 infusions to prevent side effects; the regimen may be simplified starting from the 5th infusion.
2. take anlotinib 10 mg orally once daily for 14 consecutive days, followed by a 7-day rest period.
3. Visit the clinic once every week for checkups and tests
