  Purpose

This is a phase II randomised, double-blind, dose finding, repeat dose Phase II multicentre study of ODX for the treatment of patients with castration resistant prostate cancer (CRPC) and skeletal metastases.

The primary objective is to evaluate the relative change from baseline in response markers related to bone metabolism (alkaline phosphatase (B-ALP) and S P1NP) at 12 weeks of three different doses of ODX (3.0, 6.0 and 9.0 mg/kg ODX).

  • Time to P1NP progression [ Time Frame: Baseline and 20 weeks of treatment ]
  • Time to progression in bone [ Time Frame: Baseline and 20 weeks of treatment ]
  • Time to progression in soft tissue [ Time Frame: Baseline and 20 weeks of treatment ]
  • Use of analgesics as reported by the patient during treatment and follow-up [ Time Frame: Baseline, 20 weeks of treatment and long-term follow-up up to 24 weeks ]

  • Changes from baseline in bone metastasis by means of bone scan at each time point examined. [ Time Frame: Baseline and 20 weeks of treatment ]
  • Occurrence of symptomatic skeletal events [ Time Frame: Baseline, 20 weeks of treatment and long-term follow-up up to 24 weeks ]
  • Pain (FACT-P questionnaire) [ Time Frame: Baseline and 20 weeks of treatment ]
  • Pain (EQ-5D-5L questionnaire) [ Time Frame: Baseline and 20 weeks of treatment ]
  • Quality of life (EQ-5D-5L questionnaire) [ Time Frame: Baseline and 20 weeks of treatment ]
  • Incidence, causality and intensity of Adverse Events (AEs) [ Time Frame: Baseline, 20 weeks of treatment and long-term follow-up up to 24 weeks ]
  • Dose and duration of medications required for the treatment of AEs [ Time Frame: Baseline, 20 weeks of treatment and long-term follow-up up to 24 weeks ]

Detailed Description:

Males, diagnosed with CRPC, who fulfil the inclusion criteria and does not have any exclusion criteria, will be asked to participate in the study. The subject will be informed orally and in writing about the study procedures and give written informed consent, prior to study start.

At the screening visit the following examinations are performed: Physical examination, medical history and concomitant medication. Heart rate, blood pressure, weight, height, body temperature and respiratory rate are measured. Blood samples are drawn and urine sample is collected. ECG is recorded. Bone scan and diagnostic CT scan are also performed. At the next visit, baseline, the subject is examined physically and heart rate, blood pressure, weight, body temperature and respiratory rate are measured, ECG is recorded, blood samples drawn and urine sample collected. FACT-P and EQ-5D-5L (European Quality of Life - 5 Dimensions with 5 levels) questionnaire are filled out by the subject. Adverse events and concomitant medication is documented and the first dose of the investigational product is given.

The subject is surveyed for 3 hours at the hospital.

The duration of the study for the individual subject will be approximately 20 weeks from screening to the follow-up visit 2 weeks after the last dose. Each subject will receive 10 doses of investigational product. After the follow-up visit, the subject enters to long-term follow-up phase which lasts approximately 2 years.

A Data Monitoring Committee (DMC) will be designated and will be responsible to monitor/review all study related safety data. After review of safety data the DMC will provide recommendation as to whether the dose escalation can proceed as planned according to the protocol.
