In most cases, you can only participate in one clinical trial at a time. This is because:

• Taking part in multiple trials could affect your safety.
• Overlapping treatments or procedures may interfere with research results.
• Ethical guidelines prevent duplicate enrollment without careful coordination.

However, you can:

• Join another trial after completing one, as long as there’s no required waiting period.
• Participate in non-interventional studies (like surveys or registries) while enrolled in a treatment trial, depending on study rules.

What if you are contacted by multiple sites?

You are always free to speak to different research teams, ask questions, and choose the trial that’s right for you.

Key Note: If you’ve already joined a trial through another platform or site, inform the research team or DecenTrialz so we can update your profile and avoid duplicate referrals.
