"About 15% of breast cancers are HER2-positive, but another 45% have low levels of HER2, and these patients are not now treated with adjuvant trastuzumab", said Louis Fehrenbacher, MD, of the Kaiser Permanente Vallejo Medical Center in California, according to a press release. "These new therapeutics have not yet been evaluated in a dedicated large, randomized trial as a potential treatment for the 30-40 percent of women with HR-positive, HER2-negative advanced breast cancer who are pre- or perimenopausal".
The MONALEESA-7 trial met its primary endpoint of progression-free survival in premenopausal women with hormone-receptor positive, human epidermal growth factor receptor-2 negative advanced breast cancer. "It is also the first trial to show that ribociclib can be safely and effectively combined with either tamoxifen or a nonsteroidal aromatase inhibitor together with ovarian suppression using goserelin". In a recent phase 2, Simon 2-stage trial, researchers found that the drug, abemaciclib, a selective CDK4/6 inhibitor, was effective in eliciting a partial treatment response in HR+/HER2- patients. The overall response rate was 51 percent for ribociclib versus 36 percent for placebo, and clinical benefit rate was 80 versus 67 percent in patients with measurable disease at baseline.
LaVar Ball has decided where his youngest sons will play next
It's unclear where the pair will end up, but it will be interesting to see what level of basketball they end up playing at. Lonzo Ball has always been the best prospect of the three brothers, and UCLA received a stellar freshman year from him.
As expected, the most frequent adverse event was neutropenia, which was reported in 76 percent of patients in the ribociclib arm compared with 8 percent in the placebo arm. All tumours in the study cohort were centrally assessed for HER2 positivity, PD-1 ligand (PD-L1) status, and quantity of tumour-infiltrating lymphocytes (TILs).
"Longer follow-up is needed to determine whether the trial will meet its secondary end point of overall survival", Tripathy said in a statement.
Province unveils plans for legalized marijuana
Queens-Shelburne MLA Kim Masland did not respond to requests for comment on the government's plans. Robert Strang suggested the legal age for use should be 21 years old.
