The Appendix Cancer PMP Research Foundation Natural History Study/Patient Registry

The ACPMP Research Foundation Appendix Cancer/PMP Patient Registry

ACPMP's first-ever patient-powered global patient registry/natural history study collects patient and caregiver information and data to fuel clinical trials and drive breakthroughs for appendix cancer and PMP. We've invested the time and resources to make our Registry regulatory grade. Our Registry operates under active, ongoing Institutional Review Board (IRB) oversight by independent ethicists. It is powered by NORD's IAMRARE®, an industry gold standard platform built to be consistent with FDA's best thinking on natural history studies.

The ACPMP Research Foundation Appendix Cancer/PMP Patient Registry is a global, patient-powered natural history study designed to systematically collect longitudinal information from individuals affected by appendix cancer and Pseudomyxoma Peritonei (PMP).

The primary aim of the Registry is to improve understanding of these rare diseases, including their characteristics, clinical course, treatment patterns, and progression over time. Information collected through the Registry will help characterize the population affected by appendix cancer and PMP, support the development of recommendations and standards of care, and provide a resource for researchers studying disease biology, treatment outcomes, and accelerate the discovery of new treatments.

Participants, caregivers, and other authorized representatives provide information through a series of online surveys that include a prompt for patients to upload pathology reports, genomic sequencing, ctDNA reports and other relevant medical documents. Retrospective and prospective data collected include sociodemographic information, medical and diagnostic history, treatments, disease progression, management of care, and quality of life. Participants are asked to return periodically to update their information, allowing changes in disease and patient experience to be evaluated over time.

The Registry also serves as a resource to support future research and clinical trial development. With appropriate review and approval, Registry data may be used by researchers conducting retrospective studies or designing prospective studies of novel treatments. The Registry may also facilitate communication with participants about research opportunities and clinical trials for which they may be eligible.

The Registry is sponsored and managed by the Appendix Cancer Pseudomyxoma Peritonei (ACPMP) Research Foundation and is hosted on the National Organization for Rare Disorders (NORD) IAMRARE® platform. The study is conducted under Institutional Review Board (IRB) oversight and follows established procedures for the collection, management, protection, and appropriate research use of participant data.
