Brief Summary

Although treatment for metastatic colorectal cancer has improved significantly over the recent years, it still remains a significant health problem representing the leading cancer by incidence in the United States of America. In the search for new therapies, monoclonal antibodies have been developed to specifically target human colon cancer cells. huA33 is an antibody that reacts with the A33 antigen which is produced by colorectal cancers. Prior studies have shown that administration of the huA33 antibody may delay the growth of tumor cells producing the specific antigen. Oxaliplatin and 5-fluorouracil (5-FU) are cytotoxic agents which are considered as standard treatment in metastatic colorectal cancer. Leucovorin (folinic acid) is a vitamin which enhances the effect of 5-FU. Eligible patients with advanced colorectal cancer will receive huA33 10 mg/m2 by intravenous (IV) infusion weekly for twelve weeks. Starting on Study Day 15 (week 3), 5-FU, leucovorin, and oxaliplatin will be administered every 2 weeks for 10 weeks. Patients will be evaluated weekly for toxicity. Blood samples will be obtained every week for hematology and serum biochemistry analysis and for determination of human anti-human antibodies (HAHA). In patients with measurable disease, tumors will be assessed by the appropriate scan at baseline and at the end of the thirteen week cycle. The primary objective of this study is to assess the safety of huA33 + 5-FU + leucovorin + oxaliplatin. The secondary objective is to measure the immunogenicity of huA33 when given in combination with 5-FU plus leucovorin and oxaliplatin and to document tumor responses.

Outcome Measures

Primary Outcomes (1)

  • Safety as Measured by the Number of Patients With Treatment Emergent Adverse Events (TEAEs), Grade 3 TEAEs, TEAEs Resulting in Death, TEAEs Related to Treatment and Serious TEAEs in Patients With Metastatic Colorectal Cancer.

    Patients were evaluated weekly for toxicity. Blood samples were obtained every week for hematology and serum biochemistry analysis. All adverse events, which occurred after the signing of informed consent were documented in the case report form. Toxicity was evaluated according to the National Cancer Institute CTCAE Scale (Version 3.0). All AEs were coded using the Medical Dictionary for Regulatory Activities (MedDRA) Version 13.1 and classified by MedDRA system organ class (SOC) and preferred term. Treatment emergent adverse events (TEAEs) are any adverse events occurring or worsening after the first administration of study drug.

    up to 26 weeks

Secondary Outcomes (2)

  • Immunogenicity of huA33 as Measured by the Number of Patients With Human Anti-human Antibodies (HAHA) When Given huA33 Together With Oxaliplatin and 5-FU Plus Leucovorin in Patients With Metastatic Colorectal Cancer.

    up to 26 weeks

  • Tumor Response in Patients With Metastatic Colorectal Cancer Receiving huA33, Oxaliplatin and 5-FU Plus Leucovorin.

    up to 26 weeks

Study Arms (1)

huA33 antibody plus chemotherapy

EXPERIMENTAL

huA33 was administered intravenously over a period of 30 minutes once a week at a dose of 10 mg/m2 for 12 weeks. Starting on day 15 and continuing every second week, oxaliplatin, 5-fluorouracil (5-FU) and leucovorin were also administered. Oxaliplatin and leucovorin were given as infusions over 2 hours. Afterwards, patients received a bolus infusion of 5-FU intravenously followed by an infusion of 5-FU over 22 hours. The doses of oxaliplatin were 85mg/m2, leucovorin 200mg/m2, 400mg/m2 of 5-FU as a bolus infusion and 600mg/m2 as a continuous infusion. A complete treatment cycle consisted of 12 weeks. Patients were eligible to receive an additional cycle in the absence of dose-limiting toxicity (DLT), immunogenicity (huA33 human anti-human antibodies {HAHA}) and disease progression.
