Trial design

CTIS Part I — objectives, methods, condition coding

Main objective

Scope: Diagnosis, Safety

The primary objective of this study is to assess the number of detected pheochromocytoma lesions, proved by histology, with [18F]mFBG PET-CT compared to the conventional CT.

Secondary objectives 1

  1. - To determine the optimal time point of [18F]mFBG PET-CT imaging via comparison of SUV values 1 and 2 hours on PET-CT imaging. - To correlate [18F]mFBG PET findings with pathology and immunohistochemistry analysis of norepinephrine transporter. - To estimate radiation dose of [18F]mFBG in normal tissues using dynamic PATLAK imaging. - To perform a safety analysis of [18F]mFBG administration on clinical symptoms by Adverse Events outcomes.

Eligibility criteria

Principal inclusion / exclusion criteria as submitted by sponsor

Inclusion criteria 1

  1. - The patient has provided written informed consent authorization before participating in the study. - The patient is ≥18 years of age at the time of consent. - The patient has a diagnosis of pheochromocytoma with a known anatomical location or laboratory findings suspicious for pheochromocytoma defined as elevated serum/plasma metanefrines. - The patient should have surgery planned. - The patient should have had a CT scan not older than 8 weeks at time of the [18F]mFBG PET-CT.. - The patient has an ECOG status of Grade 0 – 2.

Exclusion criteria 1

  1. - Patient is mentally or legally incapacitated. - Patient is pregnant or lactating. - Patient has active serious infections not controlled by antibiotics. - Patient is unable or unwilling to undergo PET-CT scanning or surgery. - Patient did receive interfering treatment between conventional CT scanning and [18F]mFBG PET-CT.

Endpoints

Primary and secondary outcome measures (English text)

Primary endpoints 1

  1. The number of detected pheochromocytoma lesions, proved by histology, with pathological [18F]mFBG uptake, defined as focal uptake above surrounding normal tissue, compared to number of lesions detected on protocollary conventional CT imaging prior to surgery.

Secondary endpoints 1

  1. 1)Optimal time point of [18F]mFBG PET-CT imaging via comparison of SUV values at 1 and 2 hours on PET-CT imaging. 2) Correlation of [18F]mFBG PET findings with pathology and immunohistochemistry analysis of norepinephrine transporter. 3) Estimation of radiation dose of [18F]mFBG in normal tissues using dynamic PATLAK imaging 4) Safety analysis of [18F]mFBG administration on clinical symptoms will be evaluated by Adverse Events outcomes
