During the development of a novel antiviral drug designed to maintain global health during a respiratory pandemic, clinical trials must be rigorously monitored. After a candidate drug successfully completes Phase I trials, it transitions to Phase II.
Which statement correctly describes the primary focus and cohort of a Phase II clinical trial?
Testing the safety, tolerability, and pharmacokinetics of the drug on a small cohort (typically 202020 to 808080) of healthy human volunteers.
Testing the drug on animal tissue models and live mammalian subjects to determine initial toxicity and therapeutic index.
Testing the drug on thousands of patients in randomised, double-blind trials to compare its clinical efficacy against existing standard treatments.
Testing the efficacy, safety, and optimal dosage of the drug on a moderate-sized cohort of patients (typically 100100100 to 300300300) who have the target disease.
