NCT00710970

Brief Summary

The major objective of this two-stage phase II study is to determine whether tamoxifen is deserving of further study in metastatic bladder cancer. Tamoxifen is expected to function as a cytostatic (and not cytotoxic) agent, and may produce more disease stability than regression. Sustained stable disease is considered to be clinically important and the more likely event. Hence, 4-month freedom from progression is chosen as the primary end-point instead of response rate. Freedom from progression is defined as the period from start of therapy to the time of objective radiologic progression. A total of 25 subjects will be enrolled, 15 during stage 1 and 10 during stage 2 of a two-stage minimax design phase II study. Pre-therapy evaluation (within 3 weeks of initiation of therapy):

  • History and physical examination (H and P)
  • Performance status (PS) assessment
  • CBC (complete blood counts)
  • CMP (complete metabolic profile)
  • Pregnancy test (in women younger than 50)
  • Computed tomography (CT) scan of the chest, abdomen and pelvis
  • Bone scan if bone pain or raised alkaline phosphatase
  • Biopsy (may use previous biopsy specimen)
  • Samples of plasma from the routine CBC and CMP will be banked indefinitely for future biomarker studies at the Scott Department of Urology. Treatment plan: Therapy will be administered as an outpatient. Tamoxifen is administered at 20 mg/day as a single daily oral dose. Clinical assessment of patients by a history and physical examination will be performed every 4 weeks (one cycle). Objective radiological assessment of response will be made every 8 weeks or earlier if clinically indicated. A CT (computerized tomography) scan of the abdomen, pelvis and chest will be performed at baseline and every 2 cycles. A response is confirmed by repeating the scans in 4 weeks. Bone scan is performed if the patient complains of new bone pain or has raised alkaline phosphatase. A radiologist who is blinded to the treatment regimen reads the scans. The RECIST criteria are used to define response. Tamoxifen is continued until progressive disease or intolerable side effects occur.

Outcome Measures

Primary Outcomes (1)

  • Number of Participants With Freedom From Progression of Cancer at 4 Months

    Clinical Assessments were performed every 4 weeks and imaging every 8 weeks or earlier if indicated. Patients were followed every month for clinical symptoms and signs of progression. Patients underwent Radiographic CT scans every 8 weeks to look for progression.

    Estimated from date of starting therapy until 4 months but up to progression or death which ever comes first.

Study Arms (1)

Single Arm Receiving 25mg Tamoxifen

EXPERIMENTAL
Drug: Tamoxifen

Interventions

Tamoxifen is administered at 20 mg/day as a single daily oral dose. Tamoxifen is continued until progressive disease or intolerable grade 3 or 4 side effects occur due to tamoxifen.

Also known as: raloxifene
Single Arm Receiving 25mg Tamoxifen

Eligibility Criteria

Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:
