Brief Summary:

Colorectal cancer (CRC) is one of the most common human malignant tumors. The incidence and mortality of colorectal cancer in our country are on the rise. Surgery-based, combined with chemotherapy, radiotherapy comprehensive treatment, is the main treatment of colorectal cancer. Surgical resection has been recognized as the primary treatment of colorectal cancer. However, due to the majority of patients already advanced at the time of diagnosis, some difficulties are brought to radical surgery. Therefore, the importance of chemotherapy for colorectal cancer gradually been clinically recognized, But rarely survive more than 18 months." In addition to chemotherapy, there is now a more ideal model of cancer treatment- molecular targeted therapies, including monoclonal antibody drugs such as cetuximab, as well as small molecule tyrosine kinases Inhibitors gefitinib and so on. Molecular targeted drugs make use of the difference in molecular biology between tumor cells and normal cells. Targeting drugs to tumor cells and inhibiting the growth and proliferation of the cells can achieve the therapeutic effect, which has the advantages of high specificity and low adverse reaction. The bio-targeted drug cetuximab is the first drug approved to marketed as an epidermal growth factor receptor (EGFR)-targeting immunoglobulin 1(IgG1)monoclonal antibody. Cetuximab, either monotherapy or combined radiotherapy and chemotherapy, can exert excellent anti-tumor activity in EGFR-positive malignant tumors and can significantly enhance the efficacy of radiotherapy and chemotherapy.

Reference to cetuximab injection, guilin sanjin Co., Ltd. and dragonboat Co., Ltd. jointly developed a recombinant anti-EGFR human mouse chimeric monoclonal antibody (R & D code: CDP1).The primary structure of CDP1 is exactly the same with cetuximab, the higher structure and Physical and chemical properties and cetuximab are highly similar. Pharmacodynamic activity in vivo and in vitro, pharmacokinetic characteristics and toxicological reactions are also similar to cetuximab. CDP1 selected with cetuximab consistent formulations, prescriptions, specifications.

CDP1 was approved by China Food and Drug Administration (No. 2016L06884) in August 2016 for clinical studies. According to the contents of the document and guidelines for biological analogs, the clinical pharmacokinetic and clinical effectiveness comparison tests of CDP1 and the safety and immunogenicity assessment are planned.


Condition or disease Intervention/treatment Phase
Colorectal Cancer Drug: anti-EGFR monoclonal antibody Drug: Cetuximab injection Phase 1

Detailed Description:

OBJECTIVES:

Primary:

To compare the pharmacokinetic characteristics of a single dose between CDP1 and the original drug Erbitux In patients with advanced metastatic colorectal cancer.

Secondary :

  1. To compare the safety and immunogenic characteristics of the single dose between CDP1 and the original drug Erbitux in patients with advanced metastatic colorectal cancer.
  2. To evaluate the pharmacokinetics and safety of CDP1 multiple administrations."

OUTLINE

The study can be divided into 3 parts:

Part 1: Single-dose Phase:

single center, parallel, randomized, single-blind trial. The original drug Erbitux as a control, CDP1 and Erbitux single-dose pharmacokinetics of the initial comparison, and at the same time safety and immunogen preliminary comparison. CDP1 group received a single administration of CDP1 250mg/m2, Erbitux group received Erbitux 250mg/m2 single administration. Two groups of subjects after a single administration into the 4-week observation period, safety observations, pharmacokinetic blood samples and immunogenic blood samples were collected. The tumor was evaluated at the end of the 4 week observation period.If the subjects did not develop the disease, or did not appear the intolerant toxicity during the observation period, they entered the period of multiple drug delivery.

Part 2: Multi-dose Phase:

Single center, single arm, open trial, evaluation of pharmacokinetics and safety with multiple doses of CDP1. Multiple administrations of two groups of subjects were followed by continuous administration of CDP1. Dosing regimen is the first administration of 400mg/m2, followed by 250mg/m2, once a week for 6 weeks.

Part 3: Follow-up Phase:

CDP1, IV, once a week, 250mg/m2, until the patient's death or the withdrawal decision of the patient and/or investigator.
