Clinical trials are research studies performed in humans to evaluate the efficacy and safety of an intervention. They are the primary method by which researchers discover if a new treatment (drug, diet, medical device) is safe and effective in humans. DNA vaccines are considered, by definition, advanced therapy medicinal products (ATMPs). ATMPs are...
