Frequently Asked Questions
What is a research study? How am I protected?
All pharmaceutical companies conduct clinical trials, or research studies, on investigational medications to determine if the new medications will provide greater benefits compared to medications currently available on the market. These medications have not yet been FDA approved. Before research studies are performed with human participants, pharmaceutical companies conduct extensive pre-clinical animal studies to determine if the investigational medications will be safe and effective in humans. Research participants are highly protected by FDA regulations as well as Good Clinical Practice guidelines. Each research participant reads and signs an informed consent prior to performing any study-related procedures. The informed consent explains the purpose of the study, procedures to be performed, associated risks or benefits of the investigational medication, and any financial compensation for participating in the study.

What is a placebo? What does double-blind mean?
A placebo is a tablet or capsule with no active ingredients and looks like the medication being tested. Double-blind means that neither you nor the research site knows who is receiving the actual study medication or placebo. Double-blinded studies utilize a placebo as a "control group" to determine the safety and effectiveness of the study medication while eliminating any biases or influences the research site may have on the participants.
