This section outlines how to update or modify the essential personal details stored in your DecenTrialz participant profile. These fields are required for matching you to clinical trials that align with eligibility criteria, regulatory standards, and communication protocols. Accurate information in this section is critical to ensuring appropriate trial opportunities are identified and shared with you.

1. First Name and Last Name

You are required to enter your full legal name as it appears on your government-issued identification. This information may be used by research sites during verification procedures and is necessary to complete formal trial enrollment steps if you proceed to a referral stage.

Important: Do not enter nicknames, abbreviations, or pseudonyms in this section. Doing so may result in mismatches or communication delays.

2. Gender

Many clinical trials are designed with gender-specific inclusion or exclusion criteria, particularly in studies involving hormonal, reproductive, or gender-influenced conditions. For this reason, DecenTrialz requests that you indicate your gender identity accurately. The following options are supported within the platform:

• Male
• Female
• Transgender
• Non-binary

Your selected gender will only be used for the purposes of trial matching and will never be shared with any research site or third party without your explicit consent.

Key Note: This field may influence which studies are shown to you. For example, certain trials may include participants of a particular gender as part of the scientific protocol approved by ethics boards.

3. Date of Birth

You must provide your full date of birth in the format (MM/DD/YYYY). This information is essential for:

• Assessing age eligibility for clinical trials, many of which have defined age ranges (e.g., 18–65 years).
• Ensuring regulatory compliance, including age-of-majority requirements for informed consent.
• Enabling personalized recommendations based on age-specific risk factors or study goals.

Key Note: Minors (under age 18) are not permitted to create a profile independently. If the platform supports pediatric trials, a parent or legal guardian must complete the account setup as the authorized representative.

4. Phone Numbers

The platform supports two types of phone number entries:

• Primary Phone Number (Required): This will be the main point of contact for all verbal communications, SMS alerts, or follow-up calls from our support team or research site coordinators (if referred).
• Alternate Phone Number (Optional): This serves as a backup in the event that the primary number is unreachable.

Both numbers must include the correct area or country code. International numbers are accepted, but you may experience varied response times depending on your local telecom infrastructure.

• Tip: Keep your contact information updated to ensure you do not miss time-sensitive updates about pre-screening steps, referral invitations, or consent timelines.

5. Email Address

This is the primary channel through which DecenTrialz will send you:

• Trial match notifications
• Account-related alerts
• Pre-screening status updates
• Communication logs and reminders

You must provide a valid and frequently checked email address. A verification required during registration, and your account setup will remain incomplete until confirmed.

Security Note: DecenTrialz does not share your email address with third parties without your written permission. Emails are stored in compliance with HIPAA, ICH-GCP, and applicable data protection laws (e.g., CCPA, GDPR).

Key Note: All fields within the Basic Information section are mandatory except for the alternate phone number. The accuracy and completeness of this data directly affect the quality and relevance of trial matches. Participants are encouraged to review and update this section regularly, especially after a change in contact details or legal name status.
