Criteria
Inclusion Criteria:

- Male patient age >18 years.

- Signed informed consent.

- Able to comply with protocol requirements.

- Patients with histologically, cytologically or biochemically documented metastatic
adenocarcinoma of the prostate, clinically refractory or resistant to hormone therapy,
as documented by progression following at least one hormonal therapy, which must
include orchidectomy or gonadotropin releasing hormone agonist (GnRHa).

- Patients with Progressive Disease (PD). PD is defined as a minimum of three
consecutive serum PSA measurements obtained at least 7 days apart within the previous
3 months of start of trial, which document progressively increasing PSA values.
Patients with progression of measurable disease (RECIST) or progression of bone
disease must also fit the criterion for PSA progression.

- Patients must have documented progression (as defined above) following anti-androgen
withdrawal of 4 weeks duration for flutamide and 6 weeks for bicalutamide or
nilutamide. For a patient who has withdrawn from anti-androgen therapy less than 6
months prior to inclusion in the trial, one of the following criteria is also
required:

- Following completion of the anti-androgen withdrawal period one PSA measurement should
be higher than the last pre-withdrawal PSA.

Or

- Following the completion of the anti-androgen withdrawal period if the PSA value has
decreased, a patient can still qualify if 2 increases in PSA are documented after the
post- withdrawal nadir.

- PSA > 10 ng/ml.

- A predicted life expectancy of at least 12 weeks.

- A maximum of one prior treatment with either chemotherapy or other non-hormonal
treatment modality.

- ECOG performance status 0-1.

- Stable analgesia requirements.

- INR Prothrombin time (PT) and partial thromboplastin time (PTT) <1.5 upper limit of
normal.

- Adequate bone marrow function defined as absolute neutrophil count (ANC) > 1.5 x 109l,
Platelet count > 100 x 109/l.

- Haemoglobin > 9.0 mg/dl.

- Serum Albumin > 2.0 g/l.

- Castrate testosterone level [< 20 ng/dl or <0.69nM (nM/L x 28.8 = ng/dl)] must be
maintained during the duration of the trial by orchidectomy or medical castration.

- Patients on oral or intravenous bisphosphonates are allowed to enter the trial as long
as they have been on bisphosphonates for a minimum of 3 months.

Exclusion Criteria:

- Prior treatment with more than one cytotoxic chemotherapy regimen.

- Known or suspected hypersensitivity to the trial drug or their excipients.

- Persistence of toxicities of prior anti-cancer therapies which are deemed to be
clinically relevant.

- Aspartate amino transferase (ast) or alanine amino transferase (alt) greater than 2.5
times the upper limit of normal, or aspartate amino transferase (ast) or alanine amino
transferase (alt) greater than 5 times the upper limit of normal in case of known
liver metastases.

- Bilirubin greater than 1.5 mg/dl (> 26 micromol/l, Si unit equivalent). Serum
creatinine greater than 2.0 g/l.

- Concomitant intercurrent illnesses including, but not limited to, ongoing or active
infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac
arrhythmia, or psychiatric illness or social situation that would limit compliance
with trial requirement or which are considered relevant for the evaluation of the
efficacy or safety of the trial drug.

- Systemic corticosteroids taken within the past 28 days before screening (inhaled
corticosteroids prescribed for bronchospasm are allowed). Patients on long-term
stable-dose steroids for concurrent illness are not excluded.

- Treatment with any investigational drug within 28 days of trial onset.

- History of other malignancies which could affect compliance with the protocol or
interpretation of results within 5-years. Patients with adequately treated basal or
squamous cell skin cancer are generally eligible.

- Patient with history or clinical evidence of CNS disease or brain metastases.

- Patients with symptoms of impending or established spinal cord compression.

- Radiotherapy within the past four weeks prior to treatment with the trial drug.

- Prior radioisotope therapy (except radium-223 which is permissible).

- Immunotherapy within the past four weeks prior to treatment with the trial drug.

- Patients unable to comply with the protocol.

- Active alcohol or drug abuse.

- Patients who do not use adequate contraception.
