Retrospective Study to Describe the Real-world Treatment Patterns and Associated Clinical Outcomes in Patients With Metastatic Castration-resistant Prostates Cancer

Study Overview
=================
Brief Summary
-----------------
This is a multi-country, multi-centre, retrospective, non-interventional cohort study planned to include patients diagnosed with mCRPC between 01 January 2016 and 31 December 2018, who have received at least 1 line of treatment (LOT) in the mCRPC setting, and have 12 months of follow-up data available.

Detailed Description
-----------------
This is a multi-country, multi-centre, retrospective, non-interventional cohort study planned to include patients diagnosed with mCRPC between 01 January 2016 and 31 December 2018, who have received at least 1 line of treatment (LOT) in the mCRPC setting, and have 12 months of follow-up data available.To describe the real-world treatment patterns in patients with mCRPC The data will be collected retrospectively between the date of diagnosis of mCRPC (index date) and the end of follow-up, i.e., until death, the last medical record entry, or the date of data extraction, whichever is the earliest. The data on different types of treatment received by the patients, sociodemographic and clinico-pathological characteristics, and healthcare utilization will be extracted from the medical records of patients (alive or deceased) into a centrally designed electronic data capture system. For the exploratory end point on real-world treatment patterns in patients with mCSPC, data on different types of treatment received by the patients, sociodemographic and clinico-pathological characteristics will be retrospectively extracted from the medical records of patients (alive or deceased) into a centrally designed electronic data capture system.

Metastatic Castration-resistant Prostates Cancer

Participation Criteria
=================
Eligibility Criteria
-----------------
Inclusion Criteria: Male patients ≥18 years of age OR legal age of being an adult in the country as per local regulations 2. Patient or next of kin/legal representative (for deceased patients at study entry, unless a waiver is granted) willing and able to provide written informed consent according to the local regulations 3. Patients with a diagnosis of metastatic (stage IV) mCRPC, confirmed by either biopsy of a metastatic tumour site or by history of biopsy-proven localized disease and evidence of metastatic disease on imaging studies (which is clearly noted in hospital/clinical records) and progression on ADT alone between 01 January 2016 and 31 December 2018 4. Availability of medical records at the participating site reflecting at least one LOT received in the mCRPC setting and 12 months of follow-up from the index date (unless the patient died or was lost to follow-up within the first 12 months after diagnosis) Exclusion Criteria: -1. Patients with a concomitant cancer at the time of diagnosis of mCRPC or those who are treated with any anti-cancer therapy indicated for other cancers within 6 months of diagnosis of mCRPC, except for non-metastatic non-melanoma skin cancers or in situ or benign neoplasms. 2. Patients unable to give an informed consent (unless a waiver is granted)

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Describe the real-world treatment patterns in patients with mCRPC | Proportion of patients receiving each treatment regimen for each LOT | 12 Months | 
| Describe the real-world treatment patterns in patients with mCRPC | Dose and DoT for each regimen for each LOT, reason(s) for stopping treatment regimen in each LOT and drug-free period D | 12 Months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Demographic and clinico-pathological profile | Describe the demographic vs clinico-pathological characteristics of patients diagnosed with mCRPC | 12 Months | 
| Survival outcomes associated with different treatment regimens used for mCRPC | Determine overall survival from the index date of mCRPC diagnosis | 12 Months | 
| Assess the real-world effectiveness | Disease progression (abstracted from clinical notes based on radiography or PSA) (including real-world progression-free survival [rwPFS] and real-world response rate [rwRR]) of different treatment regimens used for mCRPC | 12 Months | 
| BRCA1/2 and HRRm status | To characterize RCA1/2 and HRRm status in patients with mCRPC, | 12 Months |
