A Non-interventional Study for Kisqali (Ribociclib) in Combination With an Aromatase Inhibitor for Adjuvant Treatment in Patients With HR+/HER2- Early Breast Cancer at High Risk of Recurrence (CAROLEEN)

May 28, 2026 updated by: Novartis Pharmaceuticals

A Non-interventional Study for Kisqali (Ribociclib) in Combination With an Aromatase Inhibitor for Adjuvant Treatment in Patients With HR+/HER2- Early Breast Cancer at High Risk of Recurrence to Evaluate Real-world Effectiveness, Safety Profile, Patient Compliance and Quality of Life

This non-interventional observational study evaluates the real-world effectiveness and safety profile of ribociclib in combination with an aromatase inhibitor for adjuvant treatment in patients with HR+/HER2- early breast cancer at high risk of recurrence, as well as patient compliance and quality of life.

Study Overview

Detailed Description

This non-interventional study aims to provide information on real-world effectiveness, safety and tolerability, management of adverse events, QoL and patient compliance of patients with HR+/HER2- early breast cancer at high risk of recurrence treated with ribociclib in combination with an aromatase inhibitor (AI) ± luteinizing hormone-releasing hormone (LHRH) with curative intent according to the current effective local summary of product characteristics.

In order to put the results of patients treated with ribociclib into perspective, socio-economic data, data on QoL and patient compliance will also be collected from patients treated with abemaciclib + endocrine therapy (ET) ± LHRH as described in the current effective local summary of product characteristics.

To understand reasons for treatment decision, and to analyze the clinical adoption of ribociclib + AI ± LHRH after EU approval over time, baseline data will be collected from cohorts of ribociclib + AI ± LHRH, abemaciclib + ET ± LHRH, and additionally from patients treated with ET monotherapy ± LHRH and analyzed cross-sectionally.

The study is planned to be rolled out into a broad set of German and Austrian breast centers and gynecological practices to describe clinical routine in a representative subset of the local healthcare eco-system. It will gather insights into the potential benefits and risks associated with ribociclib + AI ± LHRH in the adjuvant treatment of HR+/HER2- eBC patients at high risk of recurrence. This knowledge will inform about clinical decision-making and contribute to improved patient outcomes in routine practice.

Participants' expectations regarding therapy, side effects and management (ribociclib and abemaciclib cohorts)
Time Frame: baseline
Treatment expectation assessed by a questionnaire containing 5 questions with each 5-7 ordinal answer categories with the same directionality on participants' expectations regarding therapy, side effects and management
baseline
Participants' treatment satisfaction (ribociclib and abemaciclib cohorts)
Time Frame: up to 24 months
Treatment satisfaction assessed by a questionnaire containing 5 questions with each 5-7 ordinal answer categories with the same directionality on treatment satisfaction
up to 24 months
Patients' individual perception of risk of recurrence and treatment decision
Time Frame: baseline
Patients' individual perception of risk of recurrence and treatment decision assessed by questionnaire at baseline. The questionnaire is provided in two versions, with one version containing 6 items (applicable for the ET mono cohort), and the other version containing 11 items (applicable for ribociclib and abemaciclib cohorts). Responses are primarily given by selecting from predefined options, with some questions allowing multiple answers or prioritization. The scales and response options are designed to reflect individual preferences, concerns, and decision-making processes of patients. Higher scores on the importance scale indicate a stronger motivation to reduce recurrence risk

Impact of digital health solutions applied in clinical routine on participant compliance assessed by MARS-D (ribociclib cohort)
Time Frame: up to 36 months
Medication Adherence Report Scale (MARS-D) questionnaire is a 5-item questionnaire measuring non-adherence. Each item is ranging from "never" (5 points) to "always" (1 point), with a total score 5-25 where higher scores indicate better compliance.
up to 36 months
Impact of an active participation of the participant in the treatment decision on subsequent participant compliance measured by MARS-D (ribociclib cohort)
Time Frame: up to 36 months

Participant compliance assessed by MARS-D and active participation of the participant in the treatment decision assessed by the questionnaire "Fragebogen zur partizipativen Entscheidungsfindung aus Participantensicht" (PEF-FB-9) and "Fragebogen zur partizipativen Entscheidungsfindung aus Sicht des Arztes"(PEF-FB-Doc) at baseline.

The MARS-D is a 5-item questionnaire measuring non-adherence with a total score of 5-25 where higher scores indicate better compliance.

The PEF-FB-9 is a participant completed 9 item questionnaire for participant participation in decision-making. The 9 items are rated on a 6-point scale with endpoints ranging from "does not apply at all" to "applies completely", summed up and transformed into a scale from 0 to 100. The higher the total score, the higher the perceived degree of participation.

The PEF-FB-Doc is the physician version of the PEF-FB-9.

The correlation between participation on treatment decisions and participant compliance will be presented.

Impact of participants' fear of cancer recurrence on participant compliance measured by MARS-D (ribociclib cohort)
Time Frame: up to 36 months

Participant compliance assessed by MARS-D and participants' fear of cancer recurrence assessed by the Fear of Cancer Recurrence (FCR)-1 questionnaire.

The MARS-D questionnaire is a 5-item questionnaire measuring non-adherence. Each item is ranging from "never" (5 points) to "always" (1 point), with a total score 5-25 where higher scores indicate better compliance.

The FCR-1 is a participant completed 1 item questionnaire asking the participant to describe their subjective level of fear of cancer recurrence at the given time on a scale from 0 to 100 with 100 being the greatest fear.

The correlation between participants' fear of recurrence and participant compliance will be presented.
