Clinical trials are mainly research studies that involve patients who cannot find an appropriate treatment for their affections, or patients who volunteer to be part of such a program. These trials can focus on new drugs, new therapeutic procedures, or even different combinations of treatments. These trials are very important for the medical field, as they provide important insights as they can help specialists understand the effectiveness of these treatments and techniques. It is important to mention that while for some patients these clinical trials can represent a chance to a longer life, for some they might prove to be ineffective.
