    What is Phase 2a and 2b clinical trials?

    Phase II studies are sometimes divided into Phase IIa and Phase IIb. Phase 2a is specifically designed to assess dosing requirements (how much drug should be given), whereas Phase IIb is specifically designed to study efficacy (how well the drug works at the prescribed dose(s)).

    How long do Phase 1 clinical trials last?

    What is phase 1 in a drug study?

    In addition to safety, researchers can answer other questions in a Phase 1 trial related to how much drug is measured in the blood after administration, how the drug works in the body and the side effects associated with increased dosage. Phase 2: In Phase 2 studies, researchers administer the drug to a larger group of patients ...
