Lilly Provides Update on MONARCH 2 Phase 3 Trial of Abemaciclib
"We had stringent criteria set for this interim analysis and we look forward to receiving the final MONARCH 2 results in the first half of 2017," said
The Phase 3, double-blind study, designed to evaluate the safety and efficacy of abemaciclib in combination with fulvestrant, was conducted across 142 sites worldwide. The intent-to-treat population of 669 patients was randomized to receive abemaciclib or placebo orally every 12 hours on a continuous dosing schedule, given in combination with fulvestrant at the approved dose and schedule, until disease progression. Patients enrolled in the study had experienced disease progression on or within 12 months of receiving endocrine treatment in the neoadjuvant or adjuvant setting or while receiving first-line endocrine therapy for metastatic disease. Patients who had received chemotherapy in the metastatic setting were not eligible for the study. The primary endpoint for MONARCH 2 is progression-free survival (PFS).
The trial will continue into the first half of 2017 and will include a final analysis of PFS, overall survival and safety data.
Lilly will await further data and continue to work with the
Along with MONARCH 1 and MONARCH 2, Lilly currently has three additional MONARCH trials evaluating abemaciclib in breast cancer. MONARCH 3 is a Phase 3 trial of abemaciclib in combination with a nonsteroidal aromatase inhibitor in patients with HR+, HER2- locoregionally recurrent or metastatic breast cancer. Additionally, there are two Phase 2 MONARCH trials: neoMONARCH, which is evaluating abemaciclib in combination with a nonsteroidal aromatase inhibitor in the neoadjuvant setting, and monarcHER, which is evaluating abemaciclib plus trastuzumab (with or without fulvestrant) in women with HR+, HER2+ locally advanced or metastatic breast cancer.
For more information on additional abemaciclib trials, a complete listing can be found on ClinicalTrials.gov.

Abemaciclib (LY2835219) is an investigational, oral cell cycle inhibitor, designed to block the growth of cancer cells by specifically inhibiting cyclin-dependent kinases, CDK 4 and CDK 6. In many cancers, uncontrolled cell growth arises from a loss of cell cycle regulation due to increased signaling from CDK 4 and CDK 6. Abemaciclib inhibits both CDK 4 and CDK 6, and was shown in cell-free enzymatic assays to be most active against Cyclin D 1 and CDK 4.
