PET Scanning to Evaluate Zoledronate Efficacy in Metastatic Prostate Cancer

April 10, 2019 updated by: Ulka Vaishampayan, Barbara Ann Karmanos Cancer Institute

Pilot Trial to Evaluate Change in Positron Emission Tomography Scanning (PET) as a Surrogate for Zoledronate (Zometa) Efficacy in Patients With Metastatic Prostate Cancer

The primary goal for this trial is to assess the change in PET scans with the administration of zoledronate (bisphosphonate) therapy in patients with metastatic prostate cancer. It has been established that zoledronate therapy may play a role in delaying and reducing the incidence of skeletal events. Researchers propose to evaluate the change in the uptake value of FMAU PET scan after the zoledronate therapy. It has been demonstrated that FMAU PET scans can successfully demonstrate and detect bony metastatic sites in prostate cancer.

In addition, investigators would like to evaluate the change in the level of the prostate-specific antigen (PSA) in the patient as well as outcome of bone scans.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

  • Child
  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  • Histological diagnosis of prostate cancer

  • Creatinine within 2 weeks of registration, calculated creatinine clearance > 60ml/min.
  • Minimum life expectancy of 6 months
  • Willingness to have pre-therapy PET scans performed within 2 weeks after registration and post therapy PET scan performed within 1 week after dose of Zometa (a total of 3 PET scans required)
  • Calculated creatinine clearance > 50ml/min.
  • No prior Zoledronate therapy
  • Patients must have disease progression despite testosterone suppression (level<50ng/ml); progression can be by rising PSA ( at least 2 values at least 2 weeks apart) or by new lesions on scans or progression of existing lesions on CT scan.
  • No concomitant systemic therapy for metastatic prostate cancer is allowed except LHRH analogue should be continued if necessary to maintain testosterone suppression.
  • No concomitant radiation therapy
  • Prior RT is allowed if completed at least 2 weeks prior to registration.
  • Presence of measurable or evaluable disease
  • If RT has been administered, disease outside the RT port is required.
  • Willingness to sign informed consent.
  • Registration and willingness to sign informed consent for separate PET protocol 2335 that describes the PET scan procedure.
  • Patients must have good oral hygiene which includes having a recent dental evaluation

Exclusion Criteria:

  • Patients who are unable to swallow
  • Patients with dental cavities that are likely to need dental extraction or root canal treatment as management

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Zometa & PET Scans
Zoledronate therapy & PET scan ;2 scans [about 1-2 weeks apart] will be obtained over a period of 2 weeks pretherapy to confirm reproducibility, Bone scan (within 4 weeks prior to registration), bone turnover markers, and PSA will be obtained pretherapy. After that, Zometa will be administered at a dose of 4mg IV over 15 minutes. A third PET scan will be obtained within 1-2 weeks after Zometa administration.
Drug: zoledronate therapy
Zometa will be administered at a dose of 4mg IV over 15 minutes. A third PET scan will be obtained within 1-2 weeks after Zometa administration. Intravenous (through a vein in the arm) infusion every four weeks. Dose will be determined by kidney function.
Other Names:
  • Zometa
Device: PET Scan
2 scans [about 1-2 weeks apart] will be obtained over a period of 2 weeks pretherapy to confirm reproducibility.A third PET scan will be obtained within 1-2 weeks after Zometa administration.

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
PET Response Rate in Metastatic Prostate Cancer Patients Treated With Zoledronate Therapy.
Time Frame: Within 3 weeks
PET response rate was pre-defined in Section 5.0 of the protocol based on the magnitude of change in the mean standardized uptake value (SUVmean), which is measured at each PET scan. Specifically, a decline in SUVmean of at least 15% pre/post Zometa was taken as evidence of a "PET response". Per the protocol, Scan 2 was used as the pre-Zometa measure of SUVmean, and Scan 3 (1-2 weeks later) was used as the post-Zometa measure of SUVmean.
Within 3 weeks

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
