Alternate Title

R-Flurbiprofen in Treating Patients With Localized Prostate Cancer at Risk of Recurrence

Basic Trial Information

Phase	Type	Status	Age	Sponsor	Protocol IDs
Phase II	Treatment	Closed	18 and over	Pharmaceutical / Industry	MYRIAD-MPR-7869-001 NCT00045123

Objectives

1. Determine the effect of R-flurbiprofen on time to systemic disease progression evaluated over a minimum of 3 years in patients with localized adenocarcinoma of the prostate with an intermediate or high risk of recurrence and rising prostate-specific antigen (PSA) levels after radiotherapy alone, prostatectomy alone, or both radiotherapy and prostatectomy.
2. Determine the effect of this drug on the change in serum PSA levels over time prior to androgen-deprivation therapy (ADT) in these patients.
3. Determine the effect of this drug on the time of initiation of ADT in these patients.
4. Determine the effect of this drug on the number of patients requiring ADT.
5. Determine the safety of this drug in these patients.
6. Determine the population pharmacokinetics of R-flurbiprofen and bioinversion of R-ToS in this patient population.
7. Determine the number of patients with systemic disease progression at the end of the study.
8. Determine the time to clinical disease progression in patients treated with this drug.
9. Determine the time to prostate cancer-related mortality and time to all cause mortality in patients treated with this drug.

Entry Criteria

Disease Characteristics:

• Histologically confirmed localized adenocarcinoma of the prostate (from a pre-operative core biopsy, surgical specimen, or post-therapy core biopsy)



• Gleason score 5-10 at diagnosis (the highest score is used if multiple scores are available)



• Must have undergone 1 of the following curative treatment strategies:
  • Radical prostatectomy
    • Not a candidate for radiotherapy
  • Radical prostatectomy followed by radiotherapy at the time of surgery or any time thereafter
  • Radiotherapy of the prostate and/or surrounding structures by external beam radiotherapy (EBRT), brachytherapy (BT), or a combination of EBRT and BT



• Must have 3 consecutive rising prostate-specific antigen (PSA) measurements OR meets slope criteria



• Biochemical failure, meeting 1 of the following criteria:
  • PSA at least 0.2 ng/mL post radical prostatectomy
  • PSA greater than 1.5 ng/mL after radiotherapy or appropriate calculated slope



• Testosterone at least 100 ng/mL



• No rise in PSA with concurrent clinically active prostatitis



• No metastatic prostate cancer

Prior/Concurrent Therapy:

Biologic therapy

• No prior bisphosphonates (e.g., pamidronate, alendronate, or clodronate) for palliative intent or metastasis intervention
• At least 2 months since prior chronic non-steroidal anti-inflammatory drugs (NSAIDs), including cyclooxygenase-2 (COX-2)-specific inhibitors (e.g., celecoxib or rofecoxib), administered for more than 7 days per month
• No concurrent CYP2C9 inhibitor or substrates, including but not limited to the following:
  • Phenytoin

Hematopoietic

• WBC at least 2,500/mm³
• Platelet count at least 100,000/mm³
• Hemoglobin at least 10 g/dL

Hepatic

• Bilirubin no greater than 1.5 mg/dL

• No active ulcer disease diagnosed within the past 3 months
• No upper gastrointestinal bleed requiring a transfusion within the past 3 years
• No non-steroidal anti-inflammatory drug (NSAID)-associated ulcers within the past 5 years

Other

• No known hypersensitivity to NSAIDs, including COX-2-specific inhibitors (e.g., celecoxib or rofecoxib)
• No other malignancy within the past 5 years except basal cell or squamous cell skin cancer
• No active systemic infections
• No other serious uncontrolled medical condition
• No dementia or altered mental status

Expected Enrollment

Approximately 390 patients (130 per treatment arm) will be accrued for this study within 3 years.

Outline

This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to risk of recurrence based on Gleason score at diagnosis (5-7 vs 8-10). Patients are randomized to 1 of 3 treatment arms.

• Arm I: Patients receive oral low-dose R-flurbiprofen twice daily.



• Arm II: Patients receive oral high-dose R-flurbiprofen twice daily.



• Arm III: Patients receive oral placebo twice daily.

In all arms, treatment continues for up to 5.5 years (66 months) in the absence of disease progression or unacceptable toxicity. Patients who demonstrate increased prostate-specific antigen without objective disease progression and require androgen-deprivation therapy (ADT) continue receiving R-flurbiprofen. Patients who develop local recurrence or systemic disease may withdraw from study and receive additional therapy off study.
