During clinical trials, catalysts are evaluated for their efficacy, safety, and stability. This involves rigorous testing through various phases: 1. [Preclinical Testing](): Initial tests in laboratories and on animal models to assess the catalyst's performance and potential toxicity. 2. [Phase I Trials](): Small-scale trials on healthy volunteers to determine safety and appropriate dosage. 3. [Phase II and III Trials](): Larger trials to assess the drug's efficacy, side effects, and optimal dosage.
