Inclusion criteria
* Histologically or cytologically confirmed adenocarcinoma of the prostate without neuroendocrine differentiation or small cell histology * Distant metastatic disease documented by positive bone scan or metastatic lesions on computerized tomography (CT) or magnetic resonance imaging (MRI) * Prescribed and currently (at enrollment) being treated with abiraterone acetate and prednisone (AA + P) for the treatment of Castration-resistant metastatic prostate cancer (mCRPC) according to the local product label * Having received a minimum 1 cycle of AA + P (4 weeks), and maximum 4 consecutive cycles of AA + P (16 weeks ) prior to study enrollment * Eastern Cooperative Oncology Group (ECOG) performance status grade of 0, 1 or 2 at enrollment
Exclusion criteria
* Participants who have received and terminated abiraterone acetate treatment for prostate cancer (PCa) in the past * Received an investigational drug (including investigational vaccines) or used an invasive investigational medical device less than or equal to (\<=) 30 days before the start of the study or the first data collection time point * Presence of any condition that, in the opinion of the treating physician, prohibits the participant from participating in the study or obscures the assessment of the abiraterone acetate treatment in mCRPC * Known brain metastases * Pathological finding consistent with small cell carcinoma of the prostate
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants Complaint With Treatment (Compliance Rate) | Month 12/ early withdrawal | Percentage of participants who are compliant to abiraterone acetate and prednisone (AA + P) treatment in Colombian mCRPC participants experiencing adequate response to treatment will be assessed. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Percentage of Participants With Abiteraterone Acetate and Prednisone (AA + P) Treatment Abandonment of mCRPC Participants Treated With AA + P | Month 12/ early withdrawal | Treatment abandonment will be defined as patient-driven cessation of drug administration, regardless of causality. |
| Utilization of Health Care Resources, as Measured by the Consumption of Health Care Resources Questionnaire | Baseline, Months 3, 6, 9, 12/ early withdrawal | Utilization of Health Care Resources will be measured by the Consumption of Health Care Resources Questionnaire, which includes questions related to the participant's use of health care resources related to Prostate cancer PCa: 1) Insurance type, 2) Extra or unscheduled visits to the study doctor, another physician/specialist, healthcare professional (like nurse, therapist, physiotherapist), 3) Admission to a hospital, 4) Visits to a hospital emergency room, 5) Use of an ambulance service, 6) Complementary alternative therapy visits. |
| Change From AA + P Treatment Initiation in Patient Functionality Measured by the Eastern Cooperative Oncology Group (ECOG) Scale at Baseline, Months 3, 6, 9, and 12 | AA + P treatment initiation (atleast 4 weeks prior to baseline), Baseline, Months 3, 6, 9, and 12/ early withdrawal | ECOG is a 5-point scale 0=Fully active, 1=Ambulatory, carry out work of sedentary nature, 2=Ambulatory, capable of all self-care, 3=Capable of limited self-care, confined to bed or chair more than 50% of waking hours, 4=Completely disabled, no self-care, totally confined to bed or chair, 5=Dead. |
| Change From AA + P Treatment Initiation in Prostate-Specific Antigen (PSA) Levels at Baseline, Months 3, 6, 9, and 12 | AA + P treatment initiation (atleast 4 weeks prior to baseline), Baseline, Months 3, 6, 9, and 12/ early withdrawal | — |
| Change From AA + P Treatment Initiation in Patient Pain Assessed by the Brief Pain Inventory (BPI) at Baseline, Months 3, 6, 9, and 12 | AA + P treatment initiation (atleast 4 weeks prior to baseline), Baseline, Months 3, 6, 9, and 12/ early withdrawal | Pain intensity was assessed by Brief Pain Inventory Short Form (BPI-sf) on 11-point numerical rating scale ranging from 0=no pain to 10=pain as bad as you can imagine. |
| Percentage of Participants With Abiteraterone Acetate and Prednisone (AA + P) Treatment Suspension of mCRPC Participants Treated With AA + P | Month 12/ early withdrawal | Treatment suspension will be defined as the interruption of drug administration (abiraterone acetate) for two or more cycles of administration. |
| Change From Baseline in Patient Functionality Measured by the Eastern Cooperative Oncology Group (ECOG) Scale at Months 3, 6, 9, and 12 | Baseline, Months 3, 6, 9, 12/ early withdrawal | ECOG is a 5-point scale 0=Fully active, 1=Ambulatory, carry out work of sedentary nature, 2=Ambulatory, capable of all self-care, 3=Capable of limited self-care, confined to bed or chair more than 50% of waking hours, 4=Completely disabled, no self-care, totally confined to bed or chair, 5=Dead. |
| Change From Baseline in Prostate-Specific Antigen (PSA) Levels at Months 3, 6, 9, and 12 | Baseline, Months 3, 6, 9, 12/ early withdrawal | — |
| Change From Baseline in Patient Pain Assessed by the Brief Pain Inventory (BPI) at Months 3, 6, 9, and 12 | Baseline, Months 3, 6, 9, 12/ early withdrawal | Pain intensity was assessed by Brief Pain Inventory Short Form (BPI-sf) on 11-point numerical rating scale ranging from 0=no pain to 10=pain as bad as you can imagine. |
| Change From Baseline in Patient Pain Assessed by the Pain Visual Analogue Scale (VAS) at Months 3, 6, 9, and 12 | Baseline, Months 3, 6, 9, 12/ early withdrawal | VAS is a 100 millimeter (mm) scale. Intensity of pain range: 0 mm=no pain to 100 mm=worst possible pain. |
| Overall Survival (OS) | Month 12 | The OS is defined as the time from the date of first dose of study drug to date of death from any cause. |
| Change From AA + P Treatment Initiation in Patient Pain Assessed by the Pain Visual Analogue Scale (VAS) at Baseline, Months 3, 6, 9, and 12 | AA + P treatment initiation (atleast 4 weeks prior to baseline), Baseline, Months 3, 6, 9, and 12/ early withdrawal | VAS is a 100 millimeter (mm) scale. Intensity of pain range: 0 mm=no pain to 100 mm=worst possible pain. |
