What this trial studies

This is an observational, real-world study that follows men who start apalutamide plus androgen-deprivation therapy for metastatic hormone-sensitive prostate cancer. Participants are enrolled before their first dose and must have a baseline PSA measurement. The study collects self-reported adherence and quality-of-life questionnaires over the first year and documents treatment persistence. Analysis will describe adherence rates and identify patient characteristics and behaviors associated with non-adherence, without altering clinical care.

Who should consider this trial

Good fit: Men aged 18 or older with histologically confirmed prostate adenocarcinoma and documented metastatic hormone-sensitive disease who have agreed with their physician to start apalutamide plus ADT, can provide a baseline PSA, and can complete study questionnaires.

Not a fit: Patients not starting apalutamide, those with non-metastatic disease, people unable or unwilling to complete questionnaires, or those treated outside participating French sites are unlikely to gain direct benefit from this study.

Why it matters

Potential benefit: If successful, the results could help clinicians spot patients at risk of poor adherence and design support measures to keep men on apalutamide longer.

How similar studies have performed: Real-world adherence studies of oral prostate cancer therapies have reported variable adherence and identified risk factors, but adherence-specific data for apalutamide in mHSPC are still limited.

Eligibility criteria

Inclusion criteria:

* Male (based on chromosomal composition at birth) and aged greater than or equal to (\>=) 18 years.
* Must have a histologically or cytologically confirmed diagnosis of prostate adenocarcinoma
* Must have documented metastatic hormone-sensitive prostate cancer (mHSPC)
* Must have agreed with the treating physician to initiate treatment with apalutamide (plus androgen-deprivation therapy \[ADT\]) in accordance with the current product characteristics summary, based on the physician's decision, prior to study inclusion
* Able to understand the content of the patient information sheet and has provided oral consent for data collection. Has received the information sheet and has not objected to data collection
* Must have a baseline prostate-specific antigen (PSA) level collected prior to the first administration of apalutamide.
* Must agree to complete adherence and quality-of-life questionnaires during the study, including before the first administration of apalutamide

Exclusion criteria:

* Has already received or is currently receiving apalutamide, or any other androgen receptor pathway inhibitor (ARPI; including but not limited to abiraterone acetate, darolutamide, and enzalutamide) or chemotherapy for mHSPC
* Has received an investigational drug (including vaccines) or used an invasive investigational medical device within 90 days prior to study start or data collection
* Is currently receiving active treatment for prostate cancer as part of an interventional study
* Has received ADT for mHSPC for more than 4 months prior to starting apalutamide treatment
* Has experienced progression under ADT (and thus became castration-resistant) before starting apalutamide treatment
* Beneficiary of State Medical Aid \[AME\]
