Common Questions
Is it safe to join a clinical trial?
All clinical trials at Delta are reviewed and approved by an Independent Review Board (IRB) before beginning. Participant safety is the top priority. Studies follow strict FDA and ICH-GCP guidelines.
Will I receive a placebo?
Some studies use placebos, but you will always be told if this is possible before you consent. If you receive a placebo, you will be informed at the end of the study and may have access to active treatment.
How much compensation will I receive?
Compensation varies by study. Each study listing includes the estimated total compensation. You are paid per completed visit, not as a lump sum, and payment is not conditional on completing the entire study.
Do I need insurance?
No. All study-related care, tests, and medications are provided free of charge. You do not need insurance to participate.
Can I leave the study if I change my mind?
Absolutely. Participation is 100% voluntary. You may withdraw at any time, for any reason, with no penalty or effect on your personal medical care.
How long do studies last?
Study duration varies widely — from a few weeks to over a year. The duration is clearly listed on each study page before you apply.
