Erbituxx（Cetuximab）是一種嵌合單克隆抗體，能夠結合於上皮生長因子受體（EGFR）上，抑制EGFR介導的信號傳導路徑，從而抑制腫瘤細胞的生長、侵襲和轉移。

Erbituxx (Cetuximab) is a chimeric monoclonal antibody that binds to the epidermal growth factor receptor (EGFR), inhibiting EGFR-mediated signal transduction pathways, thereby inhibiting tumor cell growth, invasion, and metastasis.

Erbituxx的藥物動力學包括以下特點：

• 生物利用度：靜脈輸注後完全生物利用。
• 分布：主要分布於血漿和腫瘤部位。
• 代謝：主要通過蛋白白降解。
• 排泄：主要通過腎臟排泄。

The pharmacokinetics of Erbituxx include the following characteristics:

• Bioavailability: Complete bioavailability after intravenous infusion.
• Distribution: Primarily distributed in plasma and tumor sites.
• Metabolism: Mainly degraded by proteases.
• Excretion: Primarily excreted through the kidneys.

• 已知對Cetuximab有嚴重過敏反應的病人。
• Erbituxx與內含oxaliplatin之化學治療的合併治療禁用於具RAS突變型之轉移性直腸結腸癌病人或其RAS突變狀態未知的轉移性直腸結腸癌病人。

Patients with known severe hypersensitivity reactions to Cetuximab (Grade 3 or 4; National Cancer Institute – Common Terminology Criteria for Adverse Events, CTCAE).

Erbituxx in combination with oxaliplatin-containing chemotherapy is contraindicated in patients with RAS-mutant metastatic colorectal cancer or if RAS mutation status is unknown.

Erbituxx在懷孕期間的安全性尚未確立，應在權衡利弊後謹慎使用，建議懷孕期間避免使用。

The safety of Erbituxx during pregnancy has not been established. It should be used with caution and only if the potential benefits justify the potential risks. Avoid use during pregnancy.

尚不清楚Cetuximab是否會分泌至人乳，應考慮停止哺乳或停止藥物，取決於藥物的重要性。

It is not known whether Cetuximab is excreted in human milk. Consider discontinuing nursing or the drug, taking into account the importance of the drug to the mother.

• 常見副作用包括皮膚反應（如皮疹）、輸注相關反應、呼吸困難。
• 嚴重副作用可能包括過敏反應、間質性肺疾病（ILD）、次發性感染。

Common adverse reactions include skin reactions (e.g., rash), infusion-related reactions, and dyspnea.

Serious adverse reactions may include hypersensitivity reactions, interstitial lung disease (ILD), and secondary infections.
