About this study

Official title: 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.

Read the detailed description

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.

Questions about this trial

What is this clinical trial studying?

An observational study of Appendix Cancer and Pseudomyxoma Peritonei, run by Appendix Cancer Pseudomyxoma Peritonei Research Foundation at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 17 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Margaret Najarian ((833) 227-6773 ext. 704, patientregistry@acpmp.org), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Natural history and clinical course of appendix cancer and Pseudomyxoma Peritonei (PMP) (time frame: Up to 5 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 17 Aug 2026.
