Question

phase i clinical studies study the effect of a drug on patients with the disease.

true

false

Explanation:

Define Phase I clinical trials

Phase I clinical trials primarily evaluate safety, tolerability, pharmacokinetics, and pharmacodynamics in a small group of healthy volunteers (typically 20 to 100), rather than studying the therapeutic effect on patients with the disease.

Identify Phase II clinical trials

Phase II clinical trials are the stage where the drug's efficacy (effect) and safety are first evaluated in a larger group of patients who actually have the disease or condition under study.

Evaluate the statement

The statement claims that "Phase I clinical studies study the effect of a drug on patients with the disease." Since Phase I studies focus on safety in healthy volunteers, and Phase II studies focus on efficacy in patients, the statement is false.

Answer:

• TRUE
• (B) FALSE (Correct answer)
