Clinical trials is a way to develop new ways to prevent, detect, diagnose, and treat cancer and other diseases.
It is also a way for advanced “terminal” patients to boost their hope and try an alternative approach, often for free and other time, for a fee.
For researchers and clinicians, trials are important to determining the potential benefits and safety of investigational cancer therapies.
In the conventional oncology world, clinical trials are the last step before treatments can be commercialized. They come after the completion of basic lab research and testing. Clinical testing in patients helps to understanding how a particular therapy will perform and what kinds of side effects may occur.
HOW MANY PHASES DO THESE TRIALS USUALLY HAVE ? ANSWER: FOUR
Phase I trials are the first studies to test the safety aspect of a new drug, drug combination, supplement or medical procedure.
Phase II trials evaluate drug or medical intervention effectiveness and usually involve more participants than phase I studies.
Phase III trials are designed to compare a new treatment to one or more standard treatments and are usually randomized, meaning participants are randomly divided into treatment groups and not told until the study is over whether they received a standard treatment or the new treatment.
Phase IV trials are also known as post-marketing studies. These trials provide “real-world” data on the therapy.
