SB-715992 in Treating Patients With Metastatic Prostate Cancer That Did Not Respond to Docetaxel or Paclitaxel
A Phase II Study of SB-715992 (NSC-727990, IND-70273) in Taxane-Resistant Androgen-Independent Metastatic Prostate Cancer
Study Overview
Status
Intervention / Treatment
Detailed Description
PRIMARY OBJECTIVES:
I. Determine the prostate-specific antigen response to SB-715992 in patients with hormone-refractory, androgen-independent metastatic prostate cancer that failed prior taxane-based chemotherapy.
SECONDARY OBJECTIVES:
I. Determine the median overall survival and median progression-free survival of patients treated with this drug.
II. Determine the objective response rate (confirmed and unconfirmed, complete and partial response) in patients with measurable disease treated with this drug.
III. Determine the qualitative and quantitative toxic effects of this drug in these patients.
IV. Determine, preliminarily, the pharmacokinetics and mechanism of activity of this drug in these patients.
OUTLINE: This is a multicenter study.
Patients receive SB-715992 IV over 1 hour on day 1. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.
Patients are followed every 3 months for 1 year and then every 6 months for 2 years.
PROJECTED ACCRUAL: A total of 20-40 patients will be accrued for this study within 1.3-2.7 months.

Description
Inclusion Criteria:
Histologically confirmed adenocarcinoma of the prostate
- Metastatic disease (N1 and/or M1)
- Unresponsive or refractory to androgen-deprivation therapy
- Must have received one, and only one, prior taxane-containing (docetaxel or paclitaxel) chemotherapy regimen for metastatic disease that was discontinued due to disease progression, intolerance, or patient request
Evidence of disease progression as defined by ≥ 1 of the following:
- Progression of measurable disease
- Progression of evaluable disease
Rising prostate-specific antigen (PSA)
- At least 2 consecutive rises in PSA levels, each taken ≥ 7 days apart
- PSA ≥ 5 ng/mL
- Must have pre-study PSA > 5 ng/mL
Measurable or evaluable disease
- Soft tissue disease that has been irradiated within the past 2 months is not considered measurable disease
- Soft tissue disease that has been irradiated ≥ 2 months prior to study entry is considered measurable disease provided the lesion progressed after radiation
Surgical or medical castration required
- If luteinizing hormone-releasing hormone (LHRH) agonists (leuprolide or goserelin) or LHRH antagonists (abarelix) were used, then must continue use during study therapy
No prior or concurrent brain metastases (treated or untreated)
If clinical suspicion of brain metastases, must meet the following criteria:
- Brain CT scan or MRI negative for metastatic disease within the past 56 days
- No new symptoms since radiographic evaluation
- Performance status - Zubrod 0-2
- Absolute granulocyte count ≥ 1,500/mm^3
- Platelet count ≥ 100,000/mm^3
- Hemoglobin ≥ 9 g/dL
- Bilirubin normal
- SGOT and SGPT ≤ 2.5 times upper limit of normal (ULN)
- Creatinine ≤ 1.5 times ULN
- Creatinine clearance ≥ 40 mL/min
- No symptomatic congestive heart failure
- No unstable angina pectoris
- No cardiac arrhythmia
- Fertile patients must use effective contraception
- No peripheral neuropathy ≥ grade 2
- No prior allergic reaction attributed to compounds of similar chemical or biological composition to SB-715992
- No ongoing or active infection
- No psychiatric illness or social situation that would preclude study participation
- No other uncontrolled illness
- No other malignancy within the past 5 years except adequately treated basal cell or squamous cell skin cancer or adequately treated stage I or II cancer in complete remission
- No colony-stimulating factors during the first course of study therapy
- No concurrent anticancer biologic therapy
- See Disease Characteristics
- At least 4 weeks since prior chemotherapy and recovered
- See Disease Characteristics
