This is a non-interventional, prospective, single-arm, observational study describing the real-world effectiveness, safety, and PRO and HCRU data of ribociclib combined with adjuvant ET under conditions of routine clinical practice in HR+/HER2- EBC in premenopausal, perimenopausal and postmenopausal women, or men in Saudi Arabia.
This is a non-interventional, prospective, single-arm, observational study describing the real-world effectiveness, safety, and PRO and HCRU data of ribociclib combined with adjuvant ET under conditions of routine clinical practice in HR+/HER2- EBC in premenopausal, perimenopausal, and postmenopausal women or men in Saudi Arabia. The study aims to recruit 177 patients who have been newly receiving ribociclib for up to 6 months prior to enrollment date, as per the locally approved label to which the physician has made an independent decision to prescribe ribociclib. Patients will be enrolled over a recruitment window of 9 months and will be followed up for 36 months to assess the study outcomes. It is planned to capture data at the following timepoints (+/- 1 month): Baseline, 3, 6, 12, 24, and 36 months. This is in line with the frequency of routine follow-up visits, per standard of care. Data will be collected from patients' electronic medical records in the selected sites. The planned number of sites is 6, to be selected based on feasibility reports, considering the patient pool and research capabilities. Participating sites' investigators will review all the available clinical files of patients whose ribociclib treatment decision has been made by their treating physician and will invite those who fulfill the eligibility criteria to participate in the study. Data will be entered into an electronic case report form (eCRF). All patients' data will remain anonymized, fulfilling the requirements of data protection. Data collected will include information on previous treatments received, disease history, and current treatment patterns and outcomes. Participation in the study is not intended to change the routine treatment patients receive as determined by their treating physicians; all therapeutic decisions, as well as the type and timing of disease monitoring, will be at the discretion of the treating physician.

RECRUITINGInvasive Breast Cancer-Free Survival (iBCFS)
iBCFS, defined as the time from the date of first dose to the date of the first event of invasive ipsilateral breast tumor recurrence, local/regional invasive recurrence, distant recurrence, death (any cause), or invasive contralateral BC. iBCFS will be assessed using STEEP Version 2.0 criteria (Standardized Definitions for Efficacy Endpoints in Adjuvant BC Clinical Trials), as assessed by the investigator, in patients with HR+/HER2- Anatomic Stage Group IIA(subset)/IIB/III EBC.
Time frame: 36 months
Invasive disease free survival (iDFS)
iDFS is a composite endpoint that contains invasive Ipsilateral Breast Tumor Recurrence (IBTR), loco-regional invasive recurrence, distant recurrence, death from BC, death from non-BC cause, death from unknown cause, invasive contralateral BC and second primary invasive cancer (non-breast) in patients with HR+/HER2- Anatomic Stage Group IIA(subset)/IIB//III EBC.
Time frame: Up to 36 months
Distant disease free survival (DDFS)
DDFS defined as distant recurrence, death from BC, death from non-BC cause, death from unknown cause and second primary invasive cancer (non-breast) in patients with HR+/HER2- Anatomic Stage Group IIA(subset)/IIB/III EBC.
Time frame: Up to 36 months
Frequency and severity of Adverse Events (AEs) and Serious Adverse Events (SAEs)
Frequency and severity of AEs and SAEs including laboratory findings, AST/ALT elevations and ECG abnormalities qualifying and reported as AEs.
Time frame: 36 months
Change from baseline in the physical functioning sub-scale score and global health status/QoL scale score as assessed by EORTC QLQ-C30
European Organisation for Research and Treatment of Cancer (EORTC) quality of life questionnaire (EORTC QLQ-C30) incorporates nine multi-item scales: five functional scales (Physical, Role, Cognitive, Emotional and Social Functioning); three symptom scales (Fatigue, Pain and Nausea/Vomiting); and a Global Health Status/QoL scale. Six single item scales are also included (Dyspnoea, Insomnia, Appetite Loss, Constipation, Diarrhoea and Financial Difficulties). All of the scales range in score from 0 to 100. A high score for a functional scale represents a high/healthy level of functioning whereas a high score for a symptom scale or item represents a high level of symptomatology or problems.
