Ribociclib + Fulvestrant Maintains Quality of Life While Extending Progression-Free Survival

Population

N=726 Postmenopausal women.
HR+/HER2- Advanced Breast Cancer.

1st/2nd Line or Early Relapse

Investigational

Ribociclib (600 mg) + Fulvestrant

n = 484

Control

Placebo + Fulvestrant

n = 242

Preservation of Health Status

19%
Reduction in Risk
of Definitive QOL Deterioration
Emotional Functioning: HR 0.76 (Trend to delayed deterioration)
Pain Severity: HR 0.77 (Pain control maintained)

Time to Definitive 10% Deterioration (HR)

Favors Ribociclib  |  Favors Placebo

Symptom Burden Profile

Despite the addition of a CDK4/6 inhibitor, reported symptom scores for fatigue, nausea, and vomiting were similar to the Placebo arm.

Consistent with EORTC

Clinical Recommendation

Integrate Ribociclib + Fulvestrant into first- and second-line plans. The regimen delivers significant PFS/OS gains without compromising daily quality of life. Emphasize to patients that physical and emotional functioning remains comparable to endocrine monotherapy.
