During which phase of clinical testing are 100-200 patients usually involved?
Understand the Problem
The question is asking about the specific phase of clinical testing that typically involves 100-200 patients. This relates to the different phases of clinical trials for drugs or treatments and their corresponding patient capacities.
Answer
Phase II
Phase II of clinical testing usually involves 100-200 patients.
Answer for screen readers
Phase II of clinical testing usually involves 100-200 patients.
More Information
Phase II trials focus on assessing the treatment's effectiveness and further evaluating its safety. This is a critical phase where the drug's efficacy is analyzed, often involving a placebo group or comparison group.
Tips
A common mistake is to confuse Phase II with Phase III trials, which involve a larger number of patients, usually several hundred to several thousand.
