What is Phase I and Phase II clinical trials?
Phase I trials test if a new treatment is safe and look for the best way to give the treatment. Doctors also look for signs that cancer responds to the new treatment. Phase II trials test if one type of cancer responds to the new treatment.
What is the difference between Phase 1/2 and 3 clinical drug trials?
Treatments that have been shown to work in phase II clinical trials must succeed in one more phase before they’re approved for general use. Phase III clinical trials compare the safety and effectiveness of the new treatment against the current standard treatment.
What is a Phase II clinical trial?

What is Phase 2a and 2b clinical trials?
Phase 2a are the proof of concept studies and Phase 2b are the definite dose-finding studies. Phase II’s main goal is to test effectiveness (how well the drug works) and to further evaluate safety in a larger group of subjects.
What does Phase I II mean?
A study that tests the safety, side effects, and best dose of a new treatment. Phase I/II clinical trials also test how well a certain type of cancer or other disease responds to a new treatment.
Where does Phase 1 and 2 metabolism occur?
