About this trial

The objective of this non-interventional study (NIS) is to evaluate prevalence of ESR1 mutation after endocrine therapy in the palliative setting, quality of life, tolerability, and safety and to describe treatment detail and adverse event (AE) management in postmenopausal women with locally advanced and/or metastatic ER+ HER2- ESR1-mutated breast cancer and second line treatment with elacestrant according to SmPC (Summary of product characteristics) in a real-world setting.

Trial outcomes

Primary outcomes

1

Change from baseline in EORTC global health scale

Change from baseline quality of life (QoL) over time for the global health scale of the EORTC QLQ- C30 questionnaire The EORTC QLQ- C30 global health scale ranges from 0 to 100, with higher scores indicating better quality of life.

Time frame
From Time of enrollment until month 11

Secondary outcomes

1

Time to deterioration in global health scale (EORTC QLQ-C30)

Time to deterioration in global health scale of EORTC QLQ-C30 The EORTC QLQ- C30 global health scale ranges from 0 to 100, with higher scores indicating better quality of life.

Time frame
From Time of enrollment until month 11
2

Time to deterioration in functional scores (EORTC QLQ-C30)

Time to deterioration in functional scores of EORTC QLQ-C30. The EORTC QLQ- C30 functional score ranges from 0 to 100, with higher scores indicating better quality of life.

Time frame
From Time of enrollment until month 11
3

Time to deterioration in symptom scores (EORTC QLQ-C30)

Time to deterioration in symptom scores of EORTC QLQ-C30 The EORTC QLQ- C30 symptom score ranges from 0 to 100, with lower scores indicating better quality of life.

Time frame
From Time of enrollment until month 11
4

Change from baseline in functional and symptom scores

Change from baseline in functional and symptom scores of EORTC QLQ-C30 The EORTC QLQ- C30 functional and symptom scores ranges from 0 to 100, with higher scores indicating better quality of life (for functional scores), and lower indication better quality of life for symptom scores.

Time frame
From Time of enrolment until up to 11 months after enrolment.
