Type of information: Results

phase: 3

Announcement: results

Company: Eli Lilly (USA - IN)

Product: abemaciclib (LY2835219)

Action mechanism:

  • cell cycle inhibitor/cyclin dependant kinase inhibitor. Abemaciclib (LY2835219) is a cell cycle inhibitor, designed to block the growth of cancer cells by specifically inhibiting CDK 4 and 6. Although abemaciclib inhibits both CDK 4 and CDK 6, the results from the cell-free enzymatic assays have shown that it was most active against Cyclin D 1 and CDK 4.

Trial details:

  •  The global Phase 3, double-blind, placebo-controlled study was designed to evaluate the efficacy and safety of abemaciclib in combination with an aromatase inhibitor as initial endocrine-based therapy for postmenopausal women with advanced (locoregionally recurrent or metastatic) breast cancer who have had no prior systemic treatment for advanced disease. A total of 493 patients were randomized to receive 150 mg of abemaciclib or placebo orally twice a day without interruption, given in combination with either 1 mg of anastrozole or 2.5 mg of letrozole once daily until disease progression or unacceptable toxicity. The primary endpoint of the study was PFS, with key secondary endpoints of ORR, overall survival and safety. The adverse events were generally consistent with previous studies of abemaciclib, with the most common adverse events being diarrhea, neutropenia, fatigue, and nausea. (NCT02246621)
  • Other MONARCH trials currently underway include: monarcHER, which is evaluating abemaciclib plus trastuzumab (with or without fulvestrant) in women with HR+, HER2+ locally advanced or metastatic breast cancer, and MONARCH plus, a Phase 3 study of abemaciclib in combination with endocrine therapies to support registration in China. In addition, Lilly has an ongoing Phase 3 trial evaluating abemaciclib in lung cancer. Lilly is also evaluating abemaciclib in patients with brain metastases, as well as in patients with pancreatic cancer.

Latest news:

  • • On April 24, 2017, Eli Lilly  announced that following a pre-planned interim analysis for MONARCH 3, the trial met its primary endpoint of demonstrating statistically significant improvement in progression-free survival (PFS). In addition, improvement was shown in a key secondary endpoint of objective response rate (ORR). The Phase 3 study evaluated abemaciclib in combination with an aromatase inhibitor (letrozole or anastrozole) compared to treatment with an aromatase inhibitor alone in women with hormone-receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer. Detailed efficacy and safety results will be presented at a medical meeting in the second half of the year.
  • Following this MONARCH 3 interim analysis, Lilly intends to begin global submissions of these results in the third quarter of 2017. In addition, Lilly intends to initiate MONARCH 1 and MONARCH 2 submissions beginning in the second quarter of 2017.
  • • On September 18, 2014, a Phase 3 trial sponsored by Eli Lilly  was published on the NIH website ClinicalTrials.gov for abemaciclib and is currently recruiting participants
