Clinical Trial Summary

Primary Objective:

- To demonstrate the superiority of cabazitaxel plus prednisone at 25 mg/m^2 (Arm A) or 20 mg/m^2 (Arm B) versus docetaxel plus prednisone (Arm C) in term of overall survival (OS) in participants with metastatic castration resistant prostate cancer (mCRPC) and not previously treated with chemotherapy.

Secondary Objectives:

- To evaluate safety in the 3 treatment arms.

- To compare efficacy of cabazitaxel at 20 mg/m^2 and 25 mg/m^2 to docetaxel for:

- Progression Free Survival (PFS) (RECIST 1.1)

- Tumor progression free survival (RECIST 1.1)

- Tumor response in participants with measurable disease (RECIST 1.1),

- PSA response

- PSA-Progression free survival (PSA-PFS).

- Pain response in participants with stable pain at baseline

- Pain progression free survival

- Time to occurrence of any skeletal related events (SRE)

- To compare Health-Related Quality of Life (HRQL).

- To assess the pharmacokinetics and pharmacogenomics of cabazitaxel.


Description:

Participants were treated until progressive disease, unacceptable toxicity, or participant's refusal of further study treatment. All participants were followed when on study treatment and after completion of study treatment during follow up period until death or the study cutoff date, whichever comes first.

Outcome

Type Measure Description Time frame Safety issue
Primary Overall Survival (OS) OS was defined as the time interval from the date of randomization to the date of death due to any cause. In the absence of confirmation of death, survival time was censored at the last date participant was known to be alive, or at the cut-off date if the participant's last contact was after the cut-off date. The study cut-off date for the final analysis of OS was the date when the 774th death had been observed. Analysis was performed by Kaplan-Meier method. Baseline up to death or study cut-off date, whichever was earlier (maximum duration: 51 months )
Secondary Progression Free Survival (PFS) PFS: time interval between date of randomization to date of first occurrence of any of following events: tumor progression according to Response Evaluation Criteria In Solid Tumors (RECIST) version 1.1; Prostate Specific Antigen (PSA) progression; pain progression or death due to any cause. Analysis was performed by Kaplan-Meier method. Baseline up to tumor progression, PSA progression, pain progression or death (maximum duration: 51 months)
Secondary Time to Tumor Progression Free Survival Time to tumor progression free survival was defined as the time interval between randomization and the date of first occurrence of tumor progression (assessed using RECIST version 1.1) or death, whichever was earlier. Analysis was performed by Kaplan-Meier method. Baseline up to tumor progression or death due to any cause or study cut-off date, whichever was earlier (maximum duration: 51 months)
Secondary Percentage of Participants With Overall Objective Tumor Response Overall objective tumor response was defined as having a partial response (PR) or complete response (CR) according to the RECIST version 1.1. CR was defined as disappearance of all target and non-target lesions and normalization of tumor marker level. Any pathological lymph nodes (whether target or non-target) must have reduction in short axis to <10 mm. PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters. Baseline up to DP or death due to any cause or study cut-off date, whichever was earlier (maximum duration: 51 months)
Secondary Time to Prostate Serum Antigen Progression Free Survival (PSA-PFS) Time to PSA-PFS: time interval between date of randomization & first occurrence of PSA progression/ death, whichever was earlier. PSA progression:1) In PSA responders(=50% decline from baseline PSA of =10 ng/mL):increase of =25%(at least 2 ng/mL)over nadir value, confirmed by second PSA value at least 3 weeks later;2)In PSA non-responders(not achieved =50% decline from baseline PSA =10 ng/mL):increase of =25% (at least 2 ng/mL) over baseline value, confirmed by second PSA value at least 3 weeks later;3)In participants not eligible for PSA response(baseline PSA <10 ng/mL):(a)in participants with baseline PSA>0 ng/mL&<10 ng/mL: increase in PSA by 25% (at least 2 ng/mL) above baseline level, confirmed by second PSA value at least 3weeks apart;(b)in participants with baseline value=0ng/mL: a post baseline PSA value =2ng/mL.Early rise in PSA only indicated progression if it was associated with another sign of DP or if it continued beyond 12 weeks. Analysis performed by Kaplan-Meier method. Baseline up to PSA progression or death due to any cause or study cut-off date, whichever was earlier (maximum duration: 51 months)
Secondary Percentage of Participants With PSA Response PSA response was defined as =50% decrease from baseline in serum PSA levels, confirmed by a second PSA value at least 3 weeks later in participants with baseline PSA value =10 ng/mL. Baseline up to PSA progression or death due to any cause or study cut-off date, whichever was earlier (maximum duration: 51 months)
Secondary Time to Pain Progression Free Survival (Pain PFS) Time to pain PFS was defined as the time interval between date of randomization and the date of the first occurrence of pain progression or death, whichever was earlier. Pain progression was defined as an increase of =1 point in the median present pain intensity (PPI) score from the nadir confirmed by a second assessment at least 3 weeks later or =25 % increase in the mean analgesic score from baseline, due to cancer related pain confirmed by a second assessment at least 3 weeks later or requirement for local palliative radiotherapy. PPI was rated by participant in a diary using a scale of 0=no pain, 1=mild, 2=discomforting, 3=distressing, 4=horrible 5=excruciating. Analgesic use was recorded by the participant in a diary. Analgesic score was calculated from the analgesic use data based on a table of analgesic medications, with non-narcotic medications assigned a value of 1 point and narcotic medications assigned a value of 4 points. Analysis was performed by Kaplan-Meier method. Baseline until disease progression, death or study cut-off date (maximum duration: 51 months)
Secondary Percentage of Participants With Pain Response Pain response was defined as either a =2-point decrease from baseline median PPI score without increase in analgesic score, or a =50% decrease in analgesic use from baseline mean analgesic score (only in participants with baseline mean analgesic score=10) without increase in the pain. Either criterion was maintained for 2 consecutive evaluations at least 3 weeks apart. PPI was rated by participant in a diary using a scale of 0=no pain, 1=mild, 2=discomforting, 3=distressing, 4=horrible 5=excruciating. Analgesic use was recorded by the participant in a diary. Analgesic score was calculated from the analgesic use data based on a table of analgesic medications, with non-narcotic medications assigned a value of 1 point and narcotic medications assigned a value of 4 points. Baseline until pain progression, death or study cut-off date (maximum duration: 51 months)
Secondary Skeletal Related Events (SRE) Free Survival SRE free survival was defined as the time interval between the date of randomization and the date of the occurrence of the first event defining a SRE or death due to any cause, whichever was earlier. SRE were assessed by clinical evaluation. Occurrence of SRE was defined as: pathological fracture(s) and/or spinal cord compression; need for bone irradiation, including radioisotopes or bone surgery; and change of antineoplastic therapy (including introduction of bisphosphonates or denosumab in the setting of increased pain) to treat bone pain. Analysis was performed by Kaplan-Meier method. Baseline until occurrence of first SRE or death (maximum duration: 51 months)
Secondary Change From Baseline in Functional Assessment of Cancer Therapy-Prostate (FACT-P) Total Score as a Measure of Health Related Quality of Life (HRQoL) FACT-P was a 39-item participant rated questionnaire that measures the concerns of participants with prostate cancer. It consisted of 5 sub-scales assessing physical well-being (7 items), social/family well-being (7 items), emotional well-being (6 items), functional well-being (7 items), and prostate-specific concerns (12 items). FACT-P total score was the sum of all 5 subscale scores. It ranged from 0 to156 with higher score indicated better quality of life with fewer symptoms. Baseline, Day 1 of each cycle 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 (each cycle 21-day); post-treatment follow up 1, 2, 3, 4, 5, 6 (each up to 12 weeks)
Secondary Change From Baseline in Functional Assessment of Cancer Therapy-Prostate (FACT-P):Trial Outcome Index (TOI) as a Measure of HRQoL FACT-P was a 39-item participant rated questionnaire that measures the concerns of participants with prostate cancer. It consisted of 5 sub-scales assessing physical well-being (7 items), social/family well-being (7 items), emotional well-being (6 items), functional well-being (7 items), and prostate-specific concerns (12 items). Physical well being, functional well being, and prostate-specific concerns sub-scales of the FACT-P questionnaire were combined to calculate TOI. Total TOI score ranges from 0 to 104, with higher scores representing a better quality of life with fewer symptoms. Baseline, Day 1 of each cycle 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16 (each cycle 21-day); post-treatment follow up 1, 2, 3, 4, 5, 6 (each up to 12 weeks)
