Supplement A:

Patient Registry Privacy Supplement

This Supplement applies only to individuals who choose to participate in the Surf patient registry. It supplements, and should be read together with, the main Surf Therapeutics Privacy Policy above.

A. 1

What the Patient Registry Is (and Is Not)

The patient registry is a voluntary research‑outreach program that allows individuals to share information with Surf so that they may be contacted about potential clinical research opportunities.

Participation in the registry:

Does not enroll you in a clinical trial;

Does not determine eligibility for any study;

Does not obligate you to participate in research;

Does not provide medical advice, diagnosis, or treatment; and

Does not create a physician‑patient or healthcare provider relationship.

The registry and its data‑collection activities have been reviewed and approved by an Institutional Review Board (IRB).

A. 2

If you complete the patient registry form, we may collect:

Identifiers and Contact Information

Complying with applicable laws, regulations, IRB requirements, and ethical standards.
