Clinical trials are generally divided into four phases:
Phase I: This phase focuses on assessing the safety and tolerability of the nanomaterial in a small group of healthy volunteers or patients. It helps determine the appropriate dosage. Phase II: This phase evaluates the efficacy of the nanomaterial in a larger group of patients, while continuing to assess its safety. Phase III: This phase involves large-scale testing in diverse populations to confirm efficacy, monitor side effects, and compare the nanomaterial to existing treatments. Phase IV: These are post-marketing studies conducted after the nanomaterial has been approved for use. They aim to gather additional information on long-term safety and efficacy.
