Treatment Patterns
The IBRANCE® Patient Program (IPP) was initiated to provide patients with HR+ HER2- mBC with routine access to the first-in-class CDK4/6 inhibitor treatment option, IBRANCE®. The IPP, provided 848 patients with access to IBRANCE® free-of-charge; 150 of these patients are still receiving IBRANCE® today*5,13–14
ROIS is an observational cohort study of 191 Patients who were enrolled in IPP5,15
IBRANCE® demonstrates survival benefit in RW patient populations and subgroups, with better outcomes observed when treatment is initiated early5,16
- In the overall population (N=191), 9 out of 10 patients achieved CR, PR or SD.† In the de novo‡ (n=57) population this increased to 94%5,16
- Time to best response§ was 3.5 months in the overall population5,16
- In the overall population, patients being treated with IBRANCE® achieved a mPFS of 19.5 months. In those patients who received IBRANCE® as a first-line therapy,¶ this increased to 22.5 months, with an mPFS not reached in patients with de novo‡ (n=57) mBC5,16
Median OS was not reached for patients in any population or subgroup.5
The safety profile of IBRANCE® in the ROIS trial was consistent between that seen in RCTs and other RWE, with febrile neutropenia reported in 3% of patients (n=6).1,5,16
Across clinical studies (PALOMA-1, PALOMA-2 and PALOMA-3), 1.4% of IBRANCE-treated patients experienced febrile neutropenia of any grade.1
* Data from May 202113.
† CR, PR or SD: 2%, 40% and 48%, respectively.
‡ Patients diagnosed with de novo mBC.
§ Best clinical response includes CR, PR, SD and PD.
¶ Patients with no prior treatments prescribed in the metastatic setting prior to IBRANCE® initiation.
ROIS Study Design
The overall study observation period for this analysis was from the date of breast cancer diagnosis until 24 months after initiation of IBRANCE®.5,15
Patient demographic and clinical characteristics in ROIS were consistent with the UK population of patients with breast cancer5,16–19
- The median age of patients treated with IBRANCE® was 57.0 years old5
- A total of 30% of the patients were diagnosed de novo mBC and 32% of the patients had visceral disease5
- The most common site of metastatic spread was bone5
The majority of the patients were postmenopausal by the time they were diagnosed with metastatic disease5
* First line (n=40), first-line IBRANCE® added (n=10), second line (n=7).
† Not available in the notes (n = 11).
‡ Not available in the notes due to time of initial BC diagnosis (n=11), not available in the notes (n=9).
§ Menopausal status not available for 1 male patient (1%) and not available for 5 patients (3%).
¶ Defined as time from last known date on (neo)adjuvant therapy (hormone therapy, chemotherapy or radiotherapy).
** Treatment dates are not available due to time of initial BC diagnosis (n=3), patient previously treated at a different hospital and so treatment dates are not available (n = 2), patient had no (neo)adjuvant hormone therapy (n=4), no prior hormone therapy recorded (n=16).
†† Not available in the notes (n=2).
‡‡ Not available in the notes (n=2).
§§ Includes any patient, regardless of treatment line group, with at least one hormone therapy recorded as being in the advanced/disease-modifying/metastatic setting.
In the overall population, 9 out of 10 patients achieved either CR, PR or SD.5
Patients with de novo* disease treated with IBRANCE® had a shorter median time to best response† than the overall and first-line‡ patient populations.16
* Patients diagnosed with de novo mBC.
† Best clinical response includes CR, PR, SD and PD.
‡ Patients with no prior treatments prescribed in the metastatic setting prior to IBRANCE® initiation.
In the real-world setting, a PFS benefit is observed in patients treated with IBRANCE®.5,16
Patients had a mPFS of 19.5 months in the overall patient population. When used as a first-line** treatment option, this PFS benefit of IBRANCE® extended to nearly 2 years (mPFS: 22.5 months).5,16
PFS Probability*5
Figure adapted from Palmieri C et al. 2021.
* Estimated via Kaplan–Meier analysis.
** Patients with no prior treatments prescribed in the metastatic setting prior to IBRANCE® initiation.
† Patients diagnosed with de novo metastatic BC.
‡ Patients receiving IBRANCE® after at least one other treatment in the metastatic setting.
At 2 years, mOS was not reached in any patient population or subgroup in the ROIS study this complements the data in PALOMA-2 and PALOMA-3 clinical trials.5,7-8
OS Probability*5
Figure adapted from Palmieri C et al. 2021.
* Estimated via Kaplan Meier analysis.
** Patients with no prior treatments prescribed in the metastatic setting prior to IBRANCE® initiation.
† Patients diagnosed with de novo metastatic BC.
‡ Patients receiving IBRANCE® after at least one other treatment in the metastatic setting.
The safety profile in ROIS was consistent with that seen in RCTs and previous RWE studies, with febrile neutropenia reported in 3% of patients (n=6).1,5,16
* Based on ANC values recorded in the 6 months post IBRANCE® initiation, represents the worst Grade of neutropenia experienced for each patient.
Treatment Patterns
The overall median (95% Cl) duration of IBRANCE® treatment was 19.3 (13.9–NR) months. When used as first-line* therapy or in patients diagnosed with de novo metastatic breast cancer, the median duration of treatment was not reached.5,16
* Patients with no prior treatments prescribed in the metastatic setting prior to IBRANCE® initiation.
