E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
In this trial with Ga-68 DOTATOC two groupd of patients will be investigated - patients with pituitary adenoma (PA) and patients with thyroid associateed ophtalmopathy (TAO). As the eye muscles and the pituitary is in close located the PA patients will serve as controls for the TAO patients for the eye muscles and the TAO patietns will be controls regarding the pituitary for the PA patients |
I denna undersökning med Ga-68 DOTATOC så kommer 2 grupper av patienter bli undersökta - dels patienter med hypofystumör (PA) och patienter med thyroidea associerad oftalmopati (TAO). Eftersom hypofysen och ögonmusklerna ligger nära så komemr PA patienterna att vara kontroller för TAO patienterna avseende ögonmusklerna och TAO patienterna kommer att vara kontroller för PA patienterna avseende hypofysen |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To study if it is possible to detect pituitary tumours with GA-DOTADOC PET/CT by measuring the quantification of the accumulated amount of 68-Ga-DOTATOC.
To evaluate the diagnostic accuracy of Ga-PET for orbital inflammation in comparison with clinical orbital evaluation and Magnetic resonance imaging (MRI) |
Att studera om det är möjligt att detektera hypofystumörer med Ga-PET genom att kvantifiera det ackumulerade upptaget av GA
Att evaluera den diagnostiska tillförlitligheten av Ga-PET för orbital inflammation med klinisk orbital evaluering och MRI |
|
E.2.2 | Secondary objectives of the trial |
• To study if remaining tumour tissue can be differentiated in a better way than with MRI
• To study if regrowth is earlier seen than conventional MRI
• To study the histopathological findings of sst in the tumours and correlate it to the quantification of the accumulated amount of 68-Ga-DOTATOC
• To study if it is possible to decide if remaining tissue postoperatively is scare tissue or tumour tissue by measuring quantification of the accumulated amount of GA-DOTATOC
• To study if subtypes of pituitary tumours are detected differently with GA-DOTATOC
• To study if pretreatment with Sandostatin enhances up-take of GA-DOTADOC (studied by quantification of the accumulated amount of tracer)
• To study the pharmacokinetics of GA-DOTADOC in pituitary tumours

E.2.3 | Trial contains a sub-study | Yes |
E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Yes, the PET-TAO sis a substudy of an laready by the MPA approved study on rituximab treatment in steroid resitant patients with EUDRACT nr 2011-0008899-33. PET was not included in that study but is now added. The name of the study is Rituximab (RTX) therapy in steroid resistant patients or patients relapsing after intravenous steroids with active TAO-Rescue RTX protocol 2 (2011) |
Ja PET TAO är en substudie av en av Läkemedelsverket tidigare godkänd studie med EUDRACT nr 2011-0008899-33. PEt var inte inkluderat i den studien och det läggs nu till.

E.5 End points |
E.5.1 | Primary end point(s) |
The primary outcome measurement is the standardized uptake value (SUV in the region of interest (ROI) in the pituitary and the eye muscles in comparison with the MRI in in the case of TAOpatient with CASis the responder analysis in Clinical activity score (CAS) according to Mourrits et al |
Primära utfalls variabeln är standardiserat upptagsvärde (SUV) i intressanta regioner i hypofysen ch ögonmusklerna i jämförelse med MRI och när det gäller TAO patienter också CAS according to Mourits |
