* Indicated in combination with fulvestrant for the treatment of women with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic breast cancer with disease progression following endocrine therapy. * Inidicated as monotherapy for the treatment of adult patients with HR-positive, HER2-negative advanced or metastatic breast cancer with disease progression following endocrine therapy and prior chemotherapy in the metastatic setting.
Early Breast Cancer
Verzenios in combination with endocrine therapy is indicated for the adjuvant treatment of adult patients with hormone receptor (HR) positive, human epidermal growth factor receptor 2 (HER2) negative, node positive early breast cancer at high risk of recurrence (see section 5. 1).
In pre or perimenopausal women, aromatase inhibitor endocrine therapy should be combined with a luteinising hormone-releasing hormone (LHRH) agonist.
Advanced or Metastatic Breast Cancer
Verzenios is indicated for the treatment of women with hormone receptor (HR) positive, human epidermal growth factor receptor 2 (HER2) negative locally advanced or metastatic breast cancer in combination with an aromatase inhibitor or fulvestrant as initial endocrine-based therapy, or in women who have received prior endocrine therapy.
In pre- or perimenopausal women, the endocrine therapy should be combined with a LHRH agonist.
Treatment of Ewing sarcoma
Treatment of breast cancer
Treatment of high-grade glioma, Treatment of neuroblastoma
In combination with fulvestrant, the progression-free survival for patients with HR-positive, HER2-negative breast cancer was 16.4 months compared to 9.3 months for patients taking a placebo with fulvestrant. As a monotherapy, 19.7% of patients taking abemaciclib achieved complete or partial shrinkage of their tumors for a median 8.6 months after treatment. Abemaciclib induces cell cycle arrest and exerts an antitumor activity in human tumor xenograft models. In patient investigations and a healthy volunteer study, abemaciclib is not shown to induce any clinically significant changes in the QTc interval.

Absorption
The plasma concentration of the drug increases in a dose-proportional manner. Following a single oral dose administration of 200 mg abemaciclib, the mean peak plasma concentration (Cmax) of 158 ng/mL is reached after 6 hours. The median time to reach maximum plasma concentration (Tmax) ranges from 4-6 hours following an oral administration of abemaciclib over a range of 50275 mg, but may range up to 24 hours. The absolute bioavailability of the drug is reported to be 45%.
Route of Elimination
Following a single oral dose of 150mg radiolabeled abemaciclib, approximately 81% of the total dose was recovered in feces while 3% of the dose was detected in urine. The majority of the drug is exceted as metabolites.
Volume of Distribution
The geometric mean systemic volume of distribution is approximately 690.3 L (49% CV).
Clearance
The geometric mean hepatic clearance (CL) of abemaciclib in patients was 26.0 L/h (51% CV).
Abemaciclib mainly undergoes hepatic metabolism mediated by CYP3A4. The major metabolite formed is N-desethylabemaciclib (M2), while other metabolites hydroxyabemaciclib (M20), hydroxy-N-desethylabemaciclib (M18), and an oxidative metabolite (M1) are also formed. M2, M18, and M20 are equipotent to abemaciclib and their AUCs accounted for 25%, 13%, and 26% of the total circulating analytes in plasma, respectively.
The mean plasma elimination half-life for abemaciclib in patients was 18.3 hours (72% CV).
Regulation of cell cycle is crucial in maintaining proper cell growth; dysregulated cell cycle signalling pathway is a key component in inducing hyperproliferation of cells and tumor formation in various cancers. G1 to S phase cell cycle progression, or transition through the G1 restriction point (R), is promoted by the retinoblastoma tumor suppressor protein (Rb)-mediated pathway. Activation of Rb-mediated pathway requires the interaction of Cyclin-dependent kinases (CDK) 4 and 6 with D-type cyclins, which drives the formation of active CDK4/CDK6 and subsequent phosphorylation of Rb. Rb is a tumor suppressant protein that inhibits proliferation through binding to and suppressing the activity of the E2F family of transcription factors. However, phosphorylation of Rb relieves suppression of E2F to allow expression of genes required for passage through the restriction point. This leads to increased expression of downstream signalling molecules and activity of protein kinases that promote the cell cycle progression and initiation of DNA replication. Phosphorylation of Rb and other proteins by CDK4/6 additionally leads to transcription of genes involved in cell cycle-independent activities including signal transduction, DNA repair transcriptional control, and mRNA processing. Abemaciclib selectively inhibits CDK4 and CDK6 with low nanomolar potency, inhibits Rb phosphorylation resulting in a G1 arrest and inhibition of proliferation, and its activity is specific for Rb-proficient cells. Unlike other CDK inhibitors such as [DB09073] and [DB11730], abemaciclib exhibits greater selectivity for CDK4 compared to CDK6.
