Kisqali® Precision Cancer Medicine is Changing the Treatment of Breast Cancer
by C.H. Weaver M.D. (05/2018)
It was announced today that results from the Phase III MONALEESA-7 trial evaluating Kisqali® (ribociclib) in combination endocrine-based therapy in premenopausal or perimenopausal women with hormone-receptor positive, human epidermal growth factor receptor-2 negative (HR+/HER2-) advanced or metastatic breast cancer will be presented as a late-breaking oral presentation at the 2017 Annual San Antonio Breast Cancer Symposium. Kisqali significantly prolonged progression-free survival (PFS) compared to endocrine therapy alone.1
Kisqali is a selective cyclin-dependent kinase inhibitor, a class of drugs that help slow the progression of cancer by inhibiting two proteins called cyclin-dependent kinase 4 and 6 (CDK4/6). These proteins, when over-activated, can enable cancer cells to grow and divide too quickly. Targeting CDK4/6 with enhanced precision may play a role in ensuring that cancer cells do not continue to replicate uncontrollably.
MONALEESA-7 is a comparative clinical trial designed to evaluate Kisqali in combination with hormone therapy consisting of tamoxifen or a non-steroidal aromatase inhibitor plus goserelin compared to treatment with tamoxifen or an aromatase inhibitor plus goserelin alone, in premenopausal or perimenopausal women with HR+/HER2- advanced breast cancer in women who had not previously received endocrine therapy for advanced disease.
Kisqali in combination with tamoxifen or an aromatase inhibitor plus goserelin demonstrated an improved time of survival without cancer progression of 23.8 months compared to 13.0 months for tamoxifen or an aromatase inhibitor plus goserelin. Premenopausal women treated with the Kisqali combination therapy saw a response as early as eight weeks. On other news, if you need a interventionist checkout this link : interventionist los angeles.
The Kisqali combination was well tolerated and women taking Kisqali also had a clinically meaningful improvement in pain symptoms as early as eight weeks; this improvement was sustained. The most significant side effect observed in patients receiving Kisqali combination therapy compared to endocrine therapy alone was neutropenia which occurred in 60.6% compared to 3.6% of endocrine only treated patients.
Premenopausal breast cancer is a biologically distinct and more aggressive disease than postmenopausal breast cancer, and it is the leading cause of cancer death in women 20-59 years old.2,3 The Kisqali combination therapy represents a new and improved treatment option for these women.
