  Purpose
To determine the time to progression produced by the combination of Novantrone (mitoxantrone) and Erbitux (cetuximab) versus Novantrone alone in metastatic AIPC patients previously treated with docetaxel-based chemotherapy. TTP is defined as time from the start of treatment date to the date the patient is first recorded as having disease progression, even in patients who discontinue study treatment early due to toxicity.

Condition Intervention Phase
Androgen-independent Prostate Cancer Drug: cetuximab Drug: Mitoxantrone Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Randomized Phase II Study of Mitoxantrone vs. Mitoxantrone With Cetuximab in Metastatic Androgen Independent Prostate Cancer (AIPC) Previously Treated With Docetaxel-based Chemotherapy

Primary Outcome Measures:
  • Median Time to Progression (TTP) [ Time Frame: 24 months ]
    TTP will be measured from the start of treatment date to the date the patient is first recorded as having disease progression (even in patients who discontinue study treatment early due to toxicity or death due to disease progression.


Secondary Outcome Measures:
  • 2-year Radiographically Evident Progression-free Survival (REPFS). [ Time Frame: 24 months. ]

    Radiographic progression:

    1) For bone scan, 2 unequivocal new lesions confirmed by a subsequent bone scan with at least 1 more new lesion; 2) Skeletal related event (eg, fracture, need for radiation to bone for pain, spinal cord compression, need for surgery to bone to prevent or treat a pathologic fracture).


  • Objective Response Rate (ORR) [ Time Frame: 24 months ]
    ORR = CR + PR Complete Response (CR): Disappearance of all target lesions. Partial Response (PR): At least a 30% decrease in the sum of the LD of target lesions taking as reference the baseline sum LD.

  • Median Time to Prostate-specific Antigen (PSA) Progression [ Time Frame: 24 months ]
    Defined as the time from initiation of therapy until the first 25% increase from baseline in non-responders or 50% increase from nadir in responders as defined above. A minimum increase in the PSA of 5 ng/mL will be required for progression.

  • Prostate-specific Antigen (PSA) Response Rate [ Time Frame: 24 months ]
    Defined as the fraction of patients with a ≥50% reduction in serum PSA confirmed by a second serum PSA at least 3 weeks later

  • Prostate-specific Antigen (PSA) Doubling Time [ Time Frame: 24 months ]
    PSA doubling time = [log (2)× t] ÷ [log (final PSA) - log (initial PSA)]

  • Median Progression-free Survival (PFS) [ Time Frame: 24 months ]
    PFS is measured from the date of randomization to the date of first documented disease progression or date of death, whichever comes first. If a patient neither progresses nor dies, this patient will be censored at last contact date.

  • Median Overall Survival (OS) [ Time Frame: 30 months ]
    OS is measured from the date of randomization to the date of death for a dead patient. If a patient is still alive or is lost to follow up, the patient will be censored at the last contact date.

Study Start Date: May 2008
Study Completion Date: June 2011
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm 1
Erbitux (cetuximab) and Novantrone (mitoxantrone)
Drug: cetuximab
Erbitux (cetuximab) IV over 2 hours (loading dose) on Day 1 (Cycle 1 only), followed by Erbitux (cetuximab) IV over 1 hour weekly thereafter
Other Name: Erbitux
Drug: Mitoxantrone
Novantrone (mitoxantrone) IV Day 1 + Prednisone QD for ten (10) 21-day cycles Standard androgen deprivation therapy (ADT) will be continued in all patients who enter study on LHRH agonists
Other Name: Novantrone
Experimental: Arm 2
Novantrone (mitoxantrone)
Drug: Mitoxantrone
Novantrone (mitoxantrone) IV Day 1 + Prednisone QD for ten (10) 21-day cycles Standard androgen deprivation therapy (ADT) will be continued in all patients who enter study on LHRH agonists
Other Name: Novantrone

Detailed Description:

This is a nonblinded, randomized phase II study to determine the activity of Novantrone (mitoxantrone) with or without Erbitux (cetuximab) in patients with androgen independent prostate cancer (AIPC) who have been treated previously with docetaxel chemotherapy. The Novantrone (mitoxantrone)-only treatment arm will serve as a concurrent control arm to aid in the determination of the benefit of the Novantrone (mitoxantrone)-Erbitux (cetuximab) combination in this setting.

Patients will be randomly assigned 2:1 to 1 of 2 treatment arms; 93 patients in Arm 1 and 47 patients in Arm 2. A balanced randomization procedure will be performed utilizing a code list that will be developed prior to the study opening. Because the patients will be stratified by performance status (ECOG 0 and 1 vs. ECOG 2), the list will be developed to ensure a balance between the 2 treatment arms.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   Male
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Histologically confirmed adenocarcinoma of the prostate. Note: Patients may have either measurable or non-measurable disease.
  • Radiographic evidence of regional or distant metastases
  • Current evidence of progression (by PSA and/or imaging studies) despite standard hormonal therapy.
  • Progression by PSA will be defined as: A rising PSA defined as: at least 2 rises in PSA over a reference value (PSA #1). The first rising PSA (PSA #2) must be taken at least 1 week after PSA #1. A third PSA (PSA #3) is required to be greater than PSA #2; if not, a fourth PSA (PSA #4) is required to be greater than PSA #2. Progression for nonmeasurable disease will be defined as 2 or more new bone lesions; for measurable disease, progression will be defined by standard RECIST criteria.
  • For patients who have been on antiandrogen therapy (ie, bicalutamide, flutamide, etc.), patients must have discontinued anti-androgen therapy for at least 6 weeks (4 weeks for flutamide) without evidence of an antiandrogen withdrawal response. A washout period will not be required for patients who did not respond to an antiandrogen prescribed as second line hormonal therapy. For patients whose progression is documented by PSA, the last required PSA must be after the required anti-androgen washout period (4-6 weeks as appropriate).
  • One prior docetaxel-containing regimen. Patients must have received at least 2 doses in an every 3-week schedule or 6 doses on a weekly schedule of docetaxel. Patients may have discontinued therapy due to progression, intolerance, completion of planned therapy, or other reasons. Chemotherapy treatment with any second-line regimen will not be permitted. Patients who have been previously treated with a first-line docetaxel-based doublet regimen will be eligible for this study, (eg, patients treated on a prior first-line trial containing a docetaxel/carboplatin or other docetaxel-based doublet).
  • Serum testosterone levels (See protocol for specific details) (unless surgically castrate). Patients must continue androgen deprivation with an LHRH agonist if they have not undergone orchiectomy
  • ECOG performance status
  • Laboratory criteria for entry:

    • absolute neutrophil count
    • platelets
    • bilirubin
    • AST or ALT
