Is this trial a fit for you?

Likely a good fit

Adults (≥18) in Saudi Arabia with HR+/HER2- early breast cancer (AJCC stage IIA subset/IIB/III) who have started ribociclib with adjuvant endocrine therapy within the past six months and can provide informed consent.

Probably not a fit

Patients who previously received another CDK4/6 inhibitor, are receiving ribociclib outside the adjuvant setting, are enrolled in other clinical trials, or cannot give consent are not eligible and unlikely to benefit from participation.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, non-interventional, single-arm observational study enrolling about 177 patients across selected sites in Saudi Arabia. Patients who have started ribociclib plus adjuvant endocrine therapy within the prior six months will be followed during routine care for 36 months with data captured at baseline, 3, 6, 12, 24, and 36 months. Effectiveness, safety, patient-reported outcomes, and health-care resource use will be collected from electronic medical records and eCRFs. Site investigators will invite eligible patients whose treating physicians independently decided to prescribe ribociclib.

Why it matters

Potential benefit: If successful, the results could support that ribociclib plus endocrine therapy is effective and safe for HR+/HER2- early breast cancer patients in routine care in Saudi Arabia.

How similar studies have gone: Randomized trials of adjuvant ribociclib have reported promising efficacy signals, but real-world observational data in specific populations like Saudi Arabia remain limited.

3. Male or female patients with estrogen-receptor-positive and/or progesterone-receptor-positive BC.
4. Male or female patients with HER2- BC.
5. Patients who are currently receiving ribociclib in combination with adjuvant ET as per approved local label for up to 6 months prior the enrollment date.
6. Male or female patients with American Joint Committee on Cancer (AJCC) Anatomic Stage Group IIA(subset) /IIB or Anatomic Stage Group III EBC.
7. Female patients with known menopausal status (at the time of PICF signature or initiation of adjuvant ET, whichever occurs earlier), or male.

Exclusion Criteria:

1. Ribociclib-based treatment regimen beyond adjuvant therapy for EBC.
2. Patients are currently participating in any other clinical trials.
3. Patients who previously received any other CDK4/6 inhibitor.
