Diagnostic Accuracy and Performance of 18F-PSMA-1007

June 6, 2024 updated by: Insel Gruppe AG, University Hospital Bern

Diagnostic Accuracy and Performance of 18F-PSMA-1007 in the Detection of Recurrent Prostate Cancer - a Prospective, Single-arm Study

Whereas 18F-PSMA-1007 has rapidly established itself as a radiotracer for the investigation of prostate cancer, there are no studies confirming its diagnostic performance. The purpose of this study is to determine the diagnostic performance for this radiotracer.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

In this prospective, single-armed diagnostic imaging study men undergoing standard-of-care PSMA PET/CT using [18F]PSMA-1007 shall be studied. The primary objective is to confirm the positive predictive value (PPV) of this tracer at a patient-based level by recruiting until 53 patients with follow-up to a composite reference standard are available. Secondary outcomes shall include patient based rate of pathological-scans stratified by PSA, the PPV stratified by region , interrelate agreement, frequency of indeterminate lesions and the safety and tolerability of the examination.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Study Population

The data will be obtained prospectively from patients referred for routine 18F-PSMA-11 PET/CT for recurrent prostate cancer at the university clinic for nuclear medicine, Inselspital Bern. Follow up data (further imaging, laboratory parameters and details of further treatment) will be collected up to 12 months' follow up from the date of examination.

Description

Inclusion Criteria:

  • Adult Patients referred for investigation of recurrent PC by PSMA PET/CT.
  • Patients with known biochemical recurrence of a histologically confirmed primary prostate cancer, defined as:

Post prostatectomy: two consecutive PSA > 0.2 ng/ml Post-radiotherapy: a rise of 2ng/mL > post-therapy nadir (ASTRO consensus definition)

  • Male patients >18 years old
  • PSA measured ± 4 weeks of the PSMA-PET/CT
  • Patients willing and able to consent to the informed consent document

Exclusion Criteria:

  • Patients with ADT within 6 months prior to the PSMA-PET/CT
  • Inability to provide informed, written consent
  • Patients undergoing active treatment for a second non-prostatic malignancy

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Primary objective: To confirm the PPV of the new tracer (patient-based PPV)
Time Frame: At one year follow up
The primary end point is the per patient PPV for the detection of PSMA-positive tumour lesions as confirmed by either a) histology or b) a composite reference standard of imaging and/or PSA fall following focal therapy in the absence of systemic therapy.
At one year follow up

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
• To determine the patient-based detection rate of pathologic scans (sensitivity) for the new tracer
Time Frame: Within one week of scan
Patient based detection (PET-positivity) rate (stratified by PSA value)
Within one week of scan
To explore the regional based PPV
Time Frame: At one year follow up
Region-based PPV (prostate bed, pelvic lymph nodes, extra-pelvic lymph nodes, extra-pelvic viscera and bone metastases)
At one year follow up

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
To calculate the inter-reader reliability
Time Frame: Within one month of scan
The interrater agreement (ordinal scale, no units) for PET-findings will be determined. The joint-interrate reliability will be compared by a combined assessment of Fleiss' kappa and Krippendorf's alpha.
Within one month of scan
Frequency of diagnostic pitfalls or indeterminate lesions requiring follow-up
Time Frame: Within one month of scan
The frequency of indeterminate lesions requiring follow up / indeterminate lesions will be recorded by all readers and analysed by descriptive statistics
Within one month of scan
Number of patients with adverse events.
Time Frame: Up to 48 hours follow up post scan
Patients will be contacted by phone one to three days post imaging and assessed for adverse events (AE). Any reported events will be followed up by a physician in the clinic for study related adverse events requiring further evaluation. Adverse events are as defined in supplementary materials and will be recorded using the AE form in the eCRF.
Up to 48 hours follow up post scan
