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

Ixabepilone, 16 mg/m2 or 20mg/m2, weekly x 3, in 4 week cycles, x 4 cycles. Prostatectomy 2-8 weeks after completion of chemotherapy (this was standard of care).

This protocol evaluated weekly ixabepilone prior to robotic prostatectomy for patients with high risk localized prostate cancer. PSA response rate, tumor margin status and pathologic responses were assessed.

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Male

Description

Inclusion Criteria:

  • Histologic documentation of prostatic adenocarcinoma. Patients with small cell, neuroendocrine or transitional cell carcinomas are not eligible.
  • All eligible patients must have a known Gleason sum based on biopsy or TURP at the time of registration.
  • Clinically Localized Disease: Patients must have clinical stage T1-T3a and no radiographic evidence of metastatic disease as demonstrated by:
  • Either CT or MRI of the abdomen and pelvis, that demonstrate no nodes > 1 cm: or endorectal MRI(If one or more lymph nodes(s) measures > 1 cm, a negative biopsy is required.)
  • Negative bone scan (with plain films and /or MRI and/or CT scan confirmation, if necessary).(Positive PET and Prostascint scans are not considered proof of metastatic disease.)

  • Patients must have high risk disease defined as either:

    • Gleason Score 8-10

  • No prior treatment for prostate cancer including prior surgery (excluding TURP), pelvic lymph node dissection, radiation therapy, chemotherapy or hormone therapy.
  • Patient must be appropriate candidates for radical prostatectomy with an estimated life expectancy > 10 years as determined by an urologist.
  • ECOG PS 0-1
  • Age > 18 years of age.

  • Required initial laboratory values:

    • ANC > 1500/ul
    • Platelet count > 100,000/mm3
    • Creatinine < 2.0 mg/dl
    • Serum PSA < 100 ng/ml
    • Bilirubin < upper institutional limit of normal (ULN)
    • AST/ALT < 2.5 X ULN

Exclusion Criteria:

  • Active or uncontrolled infection.
  • Patients must not have other coexistent medical condition that would preclude protocol therapy.
  • Previous severe hypersensitivity reaction to a drug formulated in CremophoreL (polyoxyethylated castor oil).
  • Grade 1 or greater neuropathy (motor or sensory) at study entry

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
