Lilly And Boehringer Ingelheim Announce Clinical Trial Collaboration In Metastatic Breast Cancer
INDIANAPOLIS, July 13, 2016 /PRNewswire/ -- Eli Lilly and Company (NYSE: LLY) and Boehringer Ingelheim today announced a new collaboration on a Phase 1b study that will evaluate the safety and tolerability of abemaciclib (LY2835219), Lilly's cyclin-dependent kinase (CDK) 4 and CDK 6 inhibitor, in combination with BI 836845, Boehringer Ingelheim's insulin-like growth factor (IGF)-1/IGF-2 ligand neutralizing antibody, in patients diagnosed with HR+, HER2- mBC. Based on the Phase 1b trial results, the collaboration has the potential to expand to Phase 2 trials in patients with HR+, HER2- mBC and other solid tumors. Enrollment is scheduled to begin in late 2016, and Boehringer Ingelheim will be the sponsor of the study program.
"We are pleased to join with Boehringer Ingelheim to study the potential of their molecule in combination with Lilly's abemaciclib, for which we have an active Phase 3 development program underway," said Richard Gaynor, M.D., senior vice president, product development and medical affairs for Lilly Oncology. "For patients living with metastatic breast cancer, the limited treatment options available make this an important area of focus for our efforts to advance the most innovative treatments."
Dr. Mehdi Shahidi, medical head, solid tumor oncology, Boehringer Ingelheim commented, "Boehringer Ingelheim is excited about initiating this collaboration with Lilly to investigate a novel combination of two compounds that have individually shown promising results in metastatic breast cancer and have a complementary mode of action. We hope that this study will lay foundations for making much needed new therapies available to patients with metastatic breast cancer."
Lilly's abemaciclib is designed to block the growth of cancer cells by specifically inhibiting CDK 4 and CDK 6. In many cancers, uncontrolled cell growth arises from a loss of control in regulating the cell cycle due to increased signaling from CDK 4 and CDK 6. Boehringer Ingelheim's BI 836845 is an IGF ligand-neutralizing antibody that binds to both IGF-1 and IGF-2 preventing activation of the respective receptor resulting in decreased growth-promoting signaling, which may decrease tumor growth. In a Phase 1b/2 trial BI 836845 has shown promising preliminary efficacy and good clinical safety in combination with everolimus and exemestane in patients with HR+ mBC.1
The rationale for the collaboration is based upon the hypothesis that these two agents, in combination, could offer a more complete pathway interference and could potentially prolong cell cycle arrest. For HR+, HER2- mBC patients, this could translate to a reversal of resistance to hormone therapy.
About Metastatic Breast Cancer
Breast cancer is the most common cancer in women worldwide with nearly 1.7 million new cases diagnosed in 2012.2 In the U.S. this year, approximately 246,600 new cases of invasive breast cancer will be diagnosed and about 40,450 women will die from breast cancer.3 Of all early stage breast cancer cases diagnosed in the U.S., approximately 30 percent will become metastatic, spreading to other parts of the body, with an estimated six to 10 percent of all new breast cancer cases initially being stage IV, or metastatic.4 Approximately 75 percent of breast cancers are hormone receptor-positive and are typically managed with endocrine therapies, including aromatase inhibitors and selective estrogen receptor modulators.5 Metastatic breast cancer is considered incurable, but is generally treatable.
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.
In 2015, the FDA granted abemaciclib Breakthrough Therapy Designation based on data from the breast cancer cohort expansion of the company's Phase 1 trial, JPBA, which studied the efficacy and safety of abemaciclib in women with advanced or metastatic breast cancer. In addition to its current MONARCH clinical trials evaluating abemaciclib in breast cancer, a Phase 3 trial of abemaciclib in lung cancer is also underway.
