Being matched to a clinical trial through DecenTrialz does not obligate you to participate. We understand that even when a study appears to align with your profile, you may decide not to move forward, and that decision is entirely yours.

This section outlines your options if you are not interested in a study after matching and explains how DecenTrialz respects and handles that choice.

You Remain in Control at Every Stage

When you are matched to a trial on the DecenTrialz platform:

• You will be presented with study details and basic eligibility information
• You must manually opt in before any of your information is shared with a research site
• If you choose not to proceed, no referral occurs and no data is shared

There is no obligation to respond and no requirement to explain your decision. Simply choosing not to click the “Refer Me” or “Proceed” button ensures your data remains private.

If You Have Already Clicked “Refer” but Changed Your Mind

If you initially opted in but later decide not to continue, you still have full control. You may:

• Decline when contacted by the research site
• Notify the site directly that you are no longer interested
• Email our support team at support@decentrialz.com, and we can assist in informing the site on your behalf

You are allowed to change your mind at any point — even after referral, even after being contacted, and even during the research site’s screening process. You are never obligated to proceed further than you feel comfortable.

Will This Affect Future Trial Matching?

No. Choosing not to proceed with one study does not affect your future use of the DecenTrialz platform. Specifically:

• You will continue to have access to other trial opportunities
• You remain eligible for other studies unless a specific study protocol requires a waiting period (e.g., no trial participation within the past 30 days)
• You can update your responses, health status, or participation preferences at any time by logging into your profile

Common and Valid Reasons for Opting Out

Participants choose not to proceed for many reasons, including:

• The study location is not convenient
• The required procedures or time commitment are not feasible
• They prefer to consult with their physician before continuing
• They are not ready to participate at this time

All reasons are valid. You are never expected to justify your decision.

Key Note: Participation in clinical research is always voluntary. DecenTrialz is committed to a no-pressure, ethics-first approach to trial matching. Declining to participate in a current opportunity does not prevent you from exploring future studies. You are welcome to return at any time to explore options that better align with your needs and preferences.
