On the Launch and Measures for Proper Use of the Anti-Cancer Agent Avastin
Avastin® is manufactured by Genentech, Inc. (California, USA) and has become a standard therapy for metastatic colorectal cancer in 88 countries including Europe and US (as of July 2006), and its launch has been awaited in Japan. Avastin® was launched by Genentech in US and by F. Hoffmann-La Roche (Basel, Switzerland) in other countries.
Because of the very limited number of patients
treated by Avastin® in domestic clinical trials, for a certain
time period after launch, its use will be limited to the medical
institutions which have the sufficient experience in cancer
chemotherapy and the ability to provide the effective emergency
treatment to the adverse drug reactions, and which are willing to
cooperate in all-case surveillance.
In preparation for the launch of Avastin®, Chugai is now investigating whether medical institutions which wanted to use it met the above conditions and conducting orientation sessions for those that did for arranging the all-case surveillance.
Following launch, Chugai will make every effort to collect and provide information on the proper use of Avastin® through its medical representatives, and Chugai's website will have a page devoted to Avastin® after its launch, where the following information is posted to provide the latest safety information.
(1) Outline of all-case surveillance
(2) Registration progress of all-case surveillance
(3) Adverse drug reactions in all-case surveillance
The launch of Avastin® in Japan provides a new option in the treatment of colorectal cancer, and securing the safety of patients who receive the drug and promoting its proper use of the top priorities.

About the post marketing surveillance of Avastin® (post
marketing survey of specific use)
The post marketing surveillance covering all patients who received Avastin® is planned to collect the data of 2,500 cases to complete within 18 months, and to be continued until the safety of the product in Japanese population is confirmed. After collecting the data of 2,500 cases, Chugai will review them and make a decision carefully if the surveillance should be terminated considering the necessity of the continuation or change of the methodology and/or contents of the survey. Results of this surveillance shall be reported to the public in future scientific meetings, as well as to the regulatory authorities.
Avastin® is the first treatment that inhibits angiogenesis - the growth of a network of blood vessels that supply nutrients and oxygen to cancerous tissues. It targets a naturally occurring protein called Vascular Endothelial Growth Factor (VEGF), a key mediator of angiogenesis, thus choking off the blood supply that is essential for the growth of the tumor and its spread throughout the body (metastasis).
