How long are phase II clinical trials?
Best Answer: Phase II clinical trials range in length but usually take 6 mos - 3 years depending on the drug and the condition. Phase III usually takes longer as there are many more patients involved. Overall, from the time a drug enters Phase I clinical trials to when it is approved can be 1-10 years. If it is for a really bad condition that doesn't have many therapeutic choices (things like cancers, etc) then the process is shortened a bit due to demand for new drugs.

A long time phase II is only the start of a new drug being tested there are several more before the FDA approves any drug for humans to use
I would say just for II till the doctors get the results they are looking for or the results they don’t want to hear then they will have to move on..
