Primary Outcome(s)
|
Timepoint(s) of evaluation of this end point: A DMC (Data Monitoring Committee) will be established to review unblinded study information during the conduct of the study. Based on its review the DMC will provide the sponsor with recommendations regarding study modification, continuation or termination.
|
Secondary Objective: The secondary objectives of this study are to compare the effects of three different doses of ODX plus best standard of care on the following: • progression free survival • overall survival • change in response markers related to bone metabolism (B-ALP and S-P1NP) at each timepoint except 12 weeks. • change in response markers related to bone metabolism (S-CTX and osteocalcin) at each timepoint sampled. • change in PSA • time to PSA, ALP and P1NP progression • pain (FACT-P and EQ-5D-5L questionnaire) • analgesic consumption • therapy response based on changes in tumor cell metabolism according to RECIST measured with CT. • changes from baseline in bone metastasis by means of bone scan at each time point examined. • occurrence of symptomatic skeletal events (SSEs; clinically significant pathological fracture, radiation therapy to bone, surgery to bone, or spinal cord compression) • safety, tolerability and quality of life (FACT-P and EQ-5D-5L questionnaire)
|
Primary end point(s): Relative change from baseline in response markers related to bone metabolism (B-ALP and S-P1NP) at 12 weeks of three different doses of ODX (3.0, 6.0, 9.0 mg/kg ODX).
|
Main Objective: The primary objective is to evaluate the relative change from baseline in response markers related to bone metabolism (B-ALP and S P1NP) at 12 weeks of three different doses of ODX (3.0, 6.0 and 9.0 mg/kg ODX).
|
Secondary Outcome(s)
|
Secondary end point(s): • Progression free survival, defined as time from randomization until disease progression or death from any cause • Overall survival, defined as the time from randomization to the date of death from any cause • Change from baseline in response markers related to bone metabolism (B-ALP and S-P1NP) at each time point sampled (except 12 weeks) • Change from baseline in response markers related to bone metabolism (S-CTX and osteocalcin) at each time point sampled • Change from baseline in PSA at each time point sampled • Time to PSA progression (defined as =25% increase from baseline and an absolute value increase =2 ng/mL at =12 weeks [in patients with no PSA decline from baseline] or =25% increase and an absolute value increase =2 ng/mL above nadir which is confirmed by a second value 3 or more weeks later [in patients with an initial PSA decline from baseline]) • Time to ALP progression (defined as =25% increase from baseline at =12 weeks from baseline [in patients with no total ALP decline from baseline] or =25% increase above the nadir value which is confirmed by a second value 3 or more weeks later [in patients with an initial total ALP decline from baseline]) • Time to P1NP progression (defined as =25% increase from baseline at =12 weeks from baseline [in patients with no total P1NP decline from baseline] or =25% increase above the nadir value which is confirmed by a second value 3 or more weeks later [in patients with an initial total P1NP decline from baseline]) • Time to progression in bone • Time to progression in soft tissue • Pain (FACT-P and EQ-5D-5L questionnaire) • Analgesic consumption • Therapy response based on changes from baseline according to RECIST criteria based on diagnostic CT in patients with measurable soft tissue metastases • Change from baseline in bone metastasis by means of bone scan (progression in bone will be defined as at least two or more new lesions on bone scan compared with prior scan at trial entry with a confirmatory bone scan performed 6 or more weeks later showing = 2 additional new lesions (27); therapy response will be assessed based on the difference in BSI from baseline and a threshold of 0.3 BSI-units (28)). • Occurence of symptomatic skeletal events (SSEs; symptomatic pathological fracture, palliative radiation therapy to bone, surgery to bone, or spinal cord compression) • Safety, tolerability and quality of life (FACT-P and EQ-5D-5L questionnaire)
|
Timepoint(s) of evaluation of this end point: The study starts with parallel double-blind randomization of 3 mg/kg and 6 mg/kg. After a minimum number of 12 patients have been randomized to each of the two doses, an unblinded Data Monitoring Committee (DMC) will assess whether or not the study can proceed with enrolment of further patients. The DMC will also assess whether or not the dose level of 9 mg/kg can be included into the randomization. If there should be any concerns, the DMC may recommend a third dose level lower than 9 mg/kg or even lower than 6 mg/kg, i.e., an intermediate dose between 3 and 6 mg/kg.
