What is the first stage of a clinical trial?

• A. High dose
• B. Marketing
• C. Low dose to see if the drug is safe
• D. Efficacy testing

Answer: (C)

The first stage of clinical testing is safety and dosing in humans. This is typically Phase I, where a low dose is given to a small group to evaluate safety, tolerability, and how the drug behaves in the body (pharmacokinetics). The aim is to identify any immediate adverse effects and to establish a safe dose range for later studies. Starting with a low dose minimizes risk while researchers learn how the drug is processed and how it affects people. Marketing comes after trials and regulatory approval, while efficacy testing happens in later phases to determine if the drug actually works.
