A new subgroup analysis across the MONALEESA phase III program found that patients with visceral metastases who were treated with Kisqali (ribociclib) plus endocrine therapy in the first-line setting achieved a median OS of 62.7 months compared to 52.1 months for those treated with endocrine therapy alone.
Further positive results from the phase III SERENA-6 trial showed camizestrant plus a cyclin-dependent kinase 4/6 inhibitor—palbociclib, ribociclib or abemaciclib—maintained its progression-free survival benefit with longer follow-up and delivered a statistically significant and clinically meaningful improvement in second progression-free survival, demonstrating sustained benefit beyond initial treatment.
