Amino-acid PET to track tumor response in IDH‑mutant gliomas (APPEAR)
Official title: Positron Emission Tomography-based Response Assessment in Isocitrate Dehydrogenase (IDH)-Mutant Gliomas - a Bicentric, Prospective, Observational Study
Run by LMU Klinikum · NCT07159607 · Data updated 2026-11-12
This project will test whether amino‑acid PET scans can better track tumor activity over time in adults with IDH‑mutant gliomas.

Is this trial a fit for you?
✓Likely a good fit
Adults (≥18) with histologically verified IDH‑mutant astrocytoma or oligodendroglioma who are receiving standard postoperative care and will undergo amino‑acid PET as part of routine follow‑up are ideal candidates.
✕Probably not a fit
Patients without an IDH‑mutant glioma, those not receiving routine amino‑acid PET scans, or those enrolled in other interventional experimental therapy trials are unlikely to benefit from participation.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
This is a prospective, bicentric observational effort collecting longitudinal amino‑acid PET and routine MRI data in adults with histologically confirmed IDH‑mutant astrocytoma or oligodendroglioma. Participating sites will perform PET (including FET PET) during standard postoperative care and follow-up, and imaging will be interpreted using PET RANO recommendations alongside MRI/RANO evaluations. The goal is to describe PET signal changes before, during, and after treatment to distinguish true progression from treatment‑related changes. No experimental therapies are given; the study documents imaging and clinical course under usual care.
Why it matters
Potential benefit: If successful, this work could help doctors tell true tumor growth from treatment effects and reduce unnecessary interventions.
How similar studies have gone: Amino‑acid PET has shown promise in prior glioma research and PET RANO guidelines exist, but well‑annotated longitudinal data specifically in IDH‑mutant gliomas remain limited.
