IBD (Inflammatory Bowel Disease)Phase 2PIMAFINCT06604260
FAPi-PET Imaging of in Vivo Fibrosis in Inflammatory Bowel Disease Patients
A Phase 2 study testing 68Ga-FAPi-46 in people with IBD (Inflammatory Bowel Disease) and Crohn Disease (CD), run by Dalia Lartey at 1 site in Netherlands.
Trial summary
Our main objective is to evaluate the feasibility of 68Ga-FAPi PET/CT in detecting intestinal fibrosis in patients with IBD. To this end, we will determine 68Ga-FAPi uptake in IBD in relation to cellular FAP expression in intestinal biopsies and resection specimens. Read more about this study

What is being measured
The primary outcome is the main question the study is designed to answer.
Detection of areas with increased 68Ga-FAPi uptake in Crohn's disease patients
Detection of areas with increased 68Ga-FAPi uptake (both visually as semi-quantitatively) in the terminal ileum and colon on baseline PET/CT of active Crohn's disease patients compared to bowel uptake reference values as derived in other Amsterdam UMC 68Ga-FAPi PET imaging studies in patients not suffering from IBD (when signed informed consent is available).
Measured: At baseline up to week 12 of study enrolment
Detection of areas with increased 68Ga-FAPi uptake in ulcerative colitis patients
Detection of areas with increased 68Ga-FAPi uptake (both visually as semi-quantitatively) in the terminal ileum and colon on baseline PET/CT of ulcerative colitis patients compared to bowel uptake reference values as derived in other Amsterdam UMC 68Ga-FAPi PET imaging studies in patients not suffering from IBD (when signed informed consent is available).
Measured: At baseline up to week 12 of study enrolment
Secondary outcomes (3)

Measured: At baseline up to week 12 of study enrolment
Protocol optimisation
To define optimal (single and/or dual) time point(s) post injection for imaging FAP activity in Crohn's disease and ulcerative colitis.
Measured: At baseline up to week 12 of study enrolment
Minimal tracer injection dose
Determine the minimal tracer injection dose required to have comparable disease detection performance on PET as to the full tracer injection dose PET.
Measured: At baseline up to week 12 of study enrolment

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing 68Ga-FAPi-46 in people with IBD (Inflammatory Bowel Disease) and Crohn Disease (CD), run by Dalia Lartey at 1 site in Netherlands.
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 12 inclusion and 4 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: status not confirmed, as of the sponsor's last update on 19 Sep 2024. 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 Netherlands. 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.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Dalia A Lartey, MD (+31205668160, d.a.lartey@amsterdamumc.nl), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Detection of areas with increased 68Ga-FAPi uptake in Crohn's disease patients (time frame: At baseline up to week 12 of study enrolment). The study lists 2 primary outcomes in all. 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 19 Sep 2024; AzTrials last refreshed its copy on 8 Nov 2026.
