Answer to Question 1

ANS: D
Phase IV studies may examine potential new indications for approved drugs.

Answer to Question 2

ANS: A
Phase I trials are primarily designed to assess safety. The objectives of phase I are to determine the human dosage range based on response in healthy human subjects and to identify the pharmacokinetics (i.e., absorption, distribution, metabolism/biotransformation, excretion/elimination) of the drug. Progression to the next phase occurs if no serious adverse effects are demonstrated, the drug is eliminated in a reasonable amount of time, and the dose range is below that known to induce pathology in animals.
