Abstract
Introduction
Cancer vaccines are the newest weapon in the battle against cancer. Vaccines
promise to boost the body' s natural abilities to halt the progression of the
disease. Although standard cancer treatments such as surgery, chemotherapy,
and radiation have improved the clinical outcomes of many patients, these
treatments have limitations and toxicities that can deter their utility. Thus,
there is substantial market opportunity for cancer vaccines.
Get the Answers You Need to Shape Your Strategy
- Cancer vaccination trains the patient' s own immune system to specifi cally
recognize and destroy tumor cells without harming normal cells. What
requirements must a cancer vaccine satisfy to achieve signifi cant clinical
response? Which patients are ideal candidates for cancer vaccination? Are
clinical trial data masking the true effi cacy potential of cancer vaccines?
- Manufacturers of cancer vaccines have faced considerable regulatory and
production challenges, particularly developers of personalized vaccines that
require the use of the patient' s own tissues. What are some of the diffi
culties faced by manufacturers of cancer vaccines? Which key development
questions need to be considered before a developer pursues a particular
vaccination strategy?
- Because of their ability to boost the body' s immune response to the
vaccine, cancer vaccine adjuvants have become critical components of any
cancer vaccine product. Companies in this arena should try to investigate ways
to incorporate adjuvants into their research. What are the key adjuvants now
in development for cancer vaccines, and which agent is showing the greatest
promise?
