Safety, Tolerability and Pharmacokinetics of Recombinant Anti-epidermal Growth Factor Receptor(EGFR) Monoclonal Antibody in Patients With Metastatic Colorectal Cancer

A Phase I Dose Escalation Study of the Safety, Tolerability and Pharmacokinetics of SCT200, a Recombinant Full Human Anti-epidermal Growth Factor Receptor(EGFR) Monoclonal Antibody，in Patients With Metastatic Colorectal Cancer Following Fluoropyrimidine, Irinotecan and Oxaliplatine Chemotherapy Regiment

The purpose of this study is to determine whether SCT200 is safe and tolerant in the treatment of metastatic colorectal cancer

Inclusion Criteria:

• aged from 18 to 70 years;

• having histologically confirmed metastatic colorectal cancer;

• having experienced previous treatment failures including fluoropyrimidine, irinotecan and oxaliplatine chemotherapy regiment;

• having determined wild-type KRAS tumor;

• having to have measurable or nonmeasurable disease per Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1;

• Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1; and expected survival of at least ≥3 months;

• adequate hematological, renal and liver functions:

  1. Hematological function: white blood cell count of >4.0×109/L; absolute neutrophil count of >1.5×109/ L; platelet count of >100×109/L; hemoglobin level of >90.0 g/L;
  2. Renal function: serum creatinine level of<1.5×upper limit of normal (ULN);
  3. Liver function: total bilirubin level of<1.5×ULN; aspartate amino transferase (AST) and alanine amino transferase (ALT) levels of <1.5×ULN; or <5 × ULN for patients with liver metastases;

• no other malignancies only if they had following malignancies , which were not required to treat or who had curative resection: cervical carcinoma in situ, the skin basal carcinoma or squamous cell carcinoma, bladder epithelial tumors, or only they had some malignancies requirement only surgical therapy and disease free survival≥5 years;

• chronic use of medication that could interfere with the assessment of drug-related toxicities or immunologic activity (high dose prednisone or high dose non-steroid anti-inflammatory medication);
• had recent major surgery (within 28 days);
• with symptomatically brain metastases (with the exception of clinically brain metastases stable and of no requirement further treatment);
• with active infection requirement systemic antibiotics treatment; or serious cardiovascular disease;or with evidence of active hepatitis B or C infection; or with human immunodeficiency virus infection;
• had acute pulmonary disorder; or interstitial pneumonia; or symptomatically chronic obstructive pulmonary disease (COPD) or with risk factors to COPD;
