Sample Use Guides

breast cancer: 150 milligrams (mg) Abemaciclib orally every 12 hours plus either 1 mg anastrozole or 2.5 mg letrozole orally once daily for 28 days (28 day cycles). non-small cell lung cancer: 200 milligrams (mg) abemaciclib administered, orally, every 12 hours plus best supportive care (BSC) on Days 1 to 28 (28 day cycles).
Route of Administration: Oral
It was examined the effects of LY2835219 using three head and neck squamous cell carcinoma (HNSCC) cell lines (OSC-19, FaDu, and YD-10B). Cells were treated with LY2835219 at concentrations ranging between 0.01 μM and 10 μM for 72 h. This treatment reduced cell viability at HNSCC cells. The IC50 values for LY2835219 ranged from 0.5 μM to 0.7 μM at HNSCC cells. In addition, LY2835219 inhibited colony formation with long term treatment, indicating that LY2835219 was able to effectively suppress colony formation of HNSCC cells in a dose-dependent manner. OSC-19 cells were treated with 0.1, 0.2, and 0.5 μM LY2835219, and levels of p-AKT (Ser473), p-ERK1/2 (thr202/Tyr204), and p-mTOR (Ser2448) were measured with Western blot analysis. Treatment of cells with LY2835219 inhibited phosphorylation of ERK1/2 and AKT in a dose-dependent manner. Inhibition of AKT by LY2835219 persisted for 48 h after treatment. In contrast, phosphorylation of ERK had recovered at 48 h. Unexpectedly, in spite of inhibition of AKT, LY2835219 had no effect on phosphorylation of mTOR at Ser2448, suggesting continuous activation of mTORC1.
