Reference: AQA
Testing proceeds in phases: healthy volunteers check safety and side effects, patients test effectiveness and optimum dose, and large-scale trials compare the new drug with existing treatments.
Tests of a new drug in humans that begin with very low doses to reduce the risk of harm because the effects in humans are not yet fully known.
Tests of a new drug in humans, using healthy volunteers and patients, carried out after laboratory and animal testing.
Testing involving healthy volunteers and patients, often comparing the drug with a placebo or existing treatment.
