What to expect

For those who have never participated in a clinical trial, we understand that it can feel somewhat intimidating, and may make you wonder if you should participate at all. Clinical trial participation is essential to the development of new, life-changing treatments and medicines. We need volunteers like you to help us in our mission to advance global health. That being said, it’s our duty to ensure that you are as informed as possible about what to expect when participating in paid clinical trials at Altasciences LA
