Phase I Clinical Trials

Phase I clinical trials are the first stage of testing a new drug or treatment in humans. They focus on assessing the safety, dosage, and side effects. Usually involving a small group of healthy volunteers or sometimes patients, these trials aim to determine how the body absorbs and processes the drug. The goal is to identify a safe dosage range and detect any adverse reactions. Phase I is essential for ensuring that the treatment is safe enough to proceed to later trial phases, where its effectiveness is further evaluated.
