E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
Primary localised prostate cancer, in men who opt for active treatment in the form of a radical prostatectomy |
|
E.1.1.1 | Medical condition in easily understood language |
prostate cancer that is diagnosed for the first time and is not spread but confined to the prostate, but needs active treatment |
|
E.1.1.2 | Therapeutic area | Diseases [C] - Male diseases of the urinary and reproductive systems [C12] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to determine the optimal pharmacokinetic model of 68Ga-PSMA PET/CT, so 68Ga-PSMA PET/CT results can be quantified in prostate cancer.
|
|
E.2.2 | Secondary objectives of the trial |
The secondary objectives are to determine whether the optimal kinetic model of 68Ga-PSMA PET/CT is valid (by a repeatability test) and to see if 68Ga-PSMA PET/CT could be a feasible method to exactly localize the tumour within the prostate. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
• Male aged 18 years or older • Ability to provide signed informed consent and willingness to comply with protocol requirements. • Biopsy confirmed presence of adenocarcinoma of the prostate gland • Planned/already executed mpMRI (standard of care). • Planned for radical prostatectomy (standard of care). |
|
E.4 | Principal exclusion criteria |
• Have any medical condition or other circumstances that, in the opinion of the investigator, would significantly decrease obtaining reliable data, achieving study objectives, or completing the study. (part A and B) • Have a contraindication for mpMRI. (part A and B) • Will not undergo a radical prostatectomy. (part A and B) • Claustrophobia (part A and B) • Multiple malignancies (part A and B) • Anticoagulant therapy (part A) • Obese (>120 kg) (part A) • Have undergone a transurethral resection of prostate in the past (part A and B) |
|
E.5 End points |
E.5.1 | Primary end point(s) |
This study aims to determine the optimal kinetic model for 68Ga-PSMA uptake and to design a simplified quantitative model for tracer uptake (Part A).To establish the ideal timing of performing the whole body 68Ga-PSMA PET after administration of the radiotracer and to determine the optimal (quantitative) method for measuring 68Ga-PSMA uptake (Part A). To determine whether it is feasible to exactly identify and localize the tumour within the prostate (Part A and B). To study test-retest characteristics of 68Ga PSMA PET (Part B). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
as soon as the first 8 patients have completed the study, the nuclear physicist will do the modelling, the model that is then tested is part B is analysed after the following 12 men have completed the study. |
|
E.5.2 | Secondary end point(s) |
Furthermore, we want to determine the test-retest variability of the simplified quantitative model for 68Ga-PSMA that follows from part A (Part B). Secondary, we want to assess if 68Ga-PSMA PET/CT is able to localize and identify tumour tissue within the prostate, compared to mpMRI (Part A and B).
- Quantify 68Ga-PSMA uptake kinetics in tumour lesions. - Comparison of 68Ga-PSMA PET (study visit) versus mpMRI (standard of care) regarding to tumour localization within the prostate |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
When all 20 men have completed the study and have undergone a radical prostatectomy, pathology will be compared to mpMRI and 68Ga-PSMA 11 PET/CT |
