Phase II GM-CSF Plus Mitoxantrone in Hormone Refractory Prostate Cancer

ClinicalTrials.gov Identifier: NCT00477087

Brief Summary:
The purpose of this study is to evaluate the effect of the combination of mitoxantrone and granulocyte-macrophage colony stimulating factor (GM-CSF) on progression-free survival (PFS) and overall survival (OS), in patients with hormone-refractory prostate cancer.

Condition or disease Intervention/treatment Phase
Prostatic Neoplasms Drug: Mitoxantrone Drug: GM-CSF Phase 2

Detailed Description:
This trial evaluates if the addition of GM-CSF to standard-of-care therapy after 1st-line docetaxel improves tumor control and survival. Because the 2 drugs have completely different mechanisms of action as well as non-overlapping metabolism, clinically significant drug-drug interactions are not anticipated, and therefore both drugs will be given at standard (approved) doses.

Arm Intervention/treatment
Experimental: GM-CSF Plus Mitoxantrone
GM-CSF at 250 micrograms/ m² / day subcutaneously 3 x week for 3 weeks. Participants will also receive mitoxantrone 14 mg/m² on Day 1 of each cycle. Each cycle of therapy consists 21 days.
Drug: Mitoxantrone
Mitoxantrone is an anti-cancer chemotherapy drug that is classified as an antitumor antibiotic.
Other Name: Novantrone

Drug: GM-CSF
GM-CSF is a biologic response modifier, classified as a colony stimulating factor.
Other Names:
  • Sargramostim
  • Leukine
  • Granulocyte-Macrophage Colony Stimulating Factor

Primary Outcome Measures :
  1. Progression-free Survival (PFS) [ Time Frame: 18 months ]
    Assessed as the time from the 1st dose of study drug to death or disease progression (increase >25% over baseline PSA on 2 consecutive measurements 2 weeks apart, need for palliative therapy, formation/progression of new bone lesions, or decline of >20% KPS)

Secondary Outcome Measures :
  1. Number of Participants With > 50% Decrease in Prostate-specific Antigen Levels (PSA Response) [ Time Frame: 18 months ]
    Defined as the first evidence of a total serum PSA decline of > 50% from baseline, maintained for at least 28 days, and confirmed with 2 consecutive measurements taken 2 weeks apart.

  2. Overall Survival (OS) [ Time Frame: 18 months ]
    Assessed as the time from the 1st dose of study drug to death.
