Study summary

The objective of the study is to evaluate 68Ga PSMA 11 PET/MRI and 68Ga RM2 PET/MRI for biopsy guidance in patients with suspected prostate cancer.

Read the detailed description

Primary Objective: To evaluate 68Ga PSMA 11 PET/MRI and 68Ga RM2 PET/MRI for biopsy guidance in patients with suspected prostate cancer.

Exploratory Objective:

  • Correlation of 68Ga PSMA 11 uptake and Gleason score at biopsy
  • Correlation of 68Ga RM2 and Gleason score at biopsy

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Suspected prostate cancer
  • Planned prostate
  • Able to provide written consent
  • performance status of 50 (or equivalent)

Exclusion criteria

Exclusion Criteria:

  • Patients not capable of getting PET study due to weight, claustrophobia, or inability to lay still for the duration of the exam
  • Metallic implants ( for MRI)
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

Karnofsky performance status (KPS)

A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.

Studies often ask for 60 or 70 and above. Your doctor gives the score.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
