5. Patient and Caregiver Terms
5.1 Health Profile
Patients and Caregivers may create a health profile by completing a structured health questionnaire. This profile is used solely for the purpose of matching you with relevant clinical trials. You are responsible for the accuracy of the information you provide.
5.2 Clinical Trial Matching
The Platform uses an algorithmic matching system to compare your health profile against clinical trial eligibility criteria. Match results are provided as a ranked list with relevance scores expressed as a percentage (0-100%). Matching considers factors including condition alignment, eligibility criteria, geographic proximity, and treatment history.
Matching results are informational only. A high match score does not guarantee eligibility for, acceptance into, or suitability for any clinical trial. You should always consult with your physician before making decisions about clinical trial participation.
5.3 Expression of Interest and Contact Requests
You may express interest in a matched trial or respond to contact requests from CROs. Before any personally identifiable information is shared with a CRO, the Platform will:
(a) Present you with a clear explanation of what information will be shared;
(b) Require your explicit, informed consent;
(c) Allow you to accept or decline each contact request individually.
You may withdraw your consent or decline contact requests at any time. Declining a request will not affect your access to the Platform or future matching.
5.4 No Medical Advice
The Platform does not provide medical advice, diagnosis, or treatment. Clinical trial match results should not be interpreted as a recommendation for any particular treatment. Always seek the advice of your physician or other qualified health provider with any questions regarding a medical condition or clinical trial participation.
5.5 Caregiver Authorization
If you register as a Caregiver, the following additional terms apply:
(a) Proof of Authority: You must have valid legal authority to act on behalf of the patient. Horizon may require you to provide documentation evidencing your authority, including but not limited to a power of attorney, guardianship order, court order, or a signed authorization form from the patient. Horizon reserves the right to suspend Caregiver access if satisfactory documentation is not provided upon request.
(b) Scope of Authority: You may only take actions on the Platform that are within the scope of your authority. This includes creating and managing the patient’s health profile, reviewing matched trials, and responding to contact requests on their behalf.
(c) Patient’s Continuing Rights: The patient retains all rights under these Terms and our Privacy Policy, including the right to access their account, correct their information, withdraw consent, and delete their account, regardless of Caregiver involvement. If a conflict arises between a Caregiver’s actions and the patient’s expressed wishes, the patient’s instructions will prevail.
(d) Revocation of Authority: If your authorization to act on behalf of the patient is revoked, expires, or is otherwise terminated, you must notify Horizon immediately at support@horizonnt.ca. Upon such notification, Horizon will suspend your Caregiver access to the patient’s profile. Continued use of the Platform on behalf of a patient after your authority has been revoked constitutes a violation of these Terms.
(e) Liability: You are personally responsible for any actions taken on the Platform on behalf of the patient, including the accuracy of information provided and any consent decisions made.
