Breast Cancer

In a large, diverse cohort of patients, this analysis confirms the safety and efficacy of ribociclib plus letrozole with data that are consistent with those observed in the MONALEESA trials, supporting the use of this combination in the first-line setting.

When combined with fulvestrant, alpelisib produced clinically and statistically relevant progression-free survival despite the baseline poorer prognosis in patients with hormone receptor–positive, HER2-negative, PIK3CA mutation–positive advanced breast cancer.

Patients and oncologists are prepared to make trade-offs between efficacy and toxicities, but patients appreciate toxicities impacting quality of life while endeavoring to increase survival.

In patients with metastatic hormone receptor–positive breast cancer treated previously with a CDK4/6 inhibitor, there was a lower median progression-free survival benefit from everolimus in combination with exemestane compared with those patients who had not received this combination.

In this study, a high rate of radiation toxicity was observed in patients with advanced breast cancer treated with CDK4/6 inhibitors.

Updated phase 2 study results of lerociclib (G1T38) combined with fulvestrant support continuous dosing without a drug holiday.

In the MONARCH plus study, the majority of abemaciclib-associated diarrhea events were low grade in severity and well managed by antidiarrheal medications, dose omissions, and/or dose reductions.

In this real-world setting study, similar healthcare costs and healthcare resource utilization among patients treated with ribociclib and palbociclib were observed. However, fewer inpatient days were experienced by patients treated with ribociclib when compared with abemaciclib.

Updated overall survival results from the phase 3 MONALEESA-7 trial show that in a 4-year extended follow-up study of pre- and perimenopausal patients with hormone receptor–positive, HER2-negative advanced breast cancer, ribociclib plus endocrine therapy exhibited a clinically relevant overall survival benefit.

BYLieve study results show that alpelisib combined with fulvestrant demonstrates clinically meaningful efficacy and manageable toxicity in patients with hormone receptor–positive, HER2-negative, PIK3CA mutation–positive advanced breast cancer.
