Biosimilars – Bowel Matters

Biological Medicine

Biological drugs have been used for many years to treat disease. They are sophisticated and expensive and often, difficult to access because of cost. As their patents expire, similar drugs have come onto the market. These are called Biosimilars. The competition has lowered the cost for the healthcare system and the patient.

For bowel cancer patients, there are biosimilars that are similar to Bevacizumab (Avastin). Avastin is known as the “originator” or “reference drug”. Biosimilars and not identical to the originator. No biological drug can be identical to another batch, even from the same manufacturer, because it contains living organisms. However, Biosimilars are safe and effective and pass the same checks as the originator.

The following Bevacizumab biosimilars are registered in the EU:
