Brief Summary:
The purpose of this clinical trial is to describe the toxicity biodistribution pharmacokinetics and tumour uptake of a single infusion of ch806 tagged with a trace amount of radioactive 111-Indium 111In-ch806 in patients with advanced tumours expressing the 806 antigen
Detailed Description:
This clinical research study explores the activity of the new experimental antibody ch806 in humans for the first time
Cancers arising from an organ can be cured in some cases with various combinations of surgery chemotherapy and radiotherapy However once some cancers spread to other organs treatment with commonly used methods is unlikely to cure the cancer and so treatment is then designed to control the growth of the cancer and the problems it is causing One newer treatment approach involves targeting a marker antigen called the epidermal growth factor receptor EGFR which is found on the tumour cells surface with a specially constructed monoclonal antibody mAB called ch806
Antibodies are proteins that are found in the blood Antibodies normally protect us from foreign invaders such as bacteria or viruses They help destroy these foreign substances by binding to them and activating white blood cells or blood proteins resulting in their destruction Tumour cells also have antigens which can be targeted by antibodies A receptor expressed in high amounts over-expressed on various cancer cells called the epidermal growth factor EGFR has been identified studied and targeted with a variety of antibodies
One of these antibodies monoclonal antibody 806 mAb806 was originally made from mouse protein Because mAb806 is a mouse antibody if it were given to humans the body would see it as a foreign protein and would be likely to react to it with an unwanted immune response To overcome this the structure of the original mouse antibody called mAb 806 was changed to appear more human-like and the chimeric antibody part mouse part human called ch806 was produced
The study is open to patients whose tumour is shown to express the 806 antigen by a special test Further tests are required to determine eligibility for the study These tests determine general health and include physical examination blood samples for routine tests routine tests to determine the extent of tumour prior to starting treatment with 111In-ch806 eg X-ray CT scan etc
On study 111In-ch806 is given by infusion into a vein over one hour Blood samples to determine the amount of drug in the blood pharmacokinetics are taken a number of times on the day of the 111In-ch806 infusion about every 2nd day for the first week then 2 weeks 3 weeks and 4 weeks after the infusion Blood tests are also used to monitor general health and to see if the immune system recognizes the infused antibody by making another antibody against it Such a response is called anti-ch806 antibody or HACA Gamma camera scans to see where 111In-ch806 goes in the body are done right after the first infusion and 4 more times over the next seven days The scan takes about one hour each time Visits for weekly follow up examinations and blood tests until 30 days after the infusion are combined with further gamma camera scans Tumour is reassessed 30 days after the infusion using the same type of scans as at study entry
Further treatment with a course of 111In-ch806 is not available at this time as this study is to test the safety of a single infusion only
