DUBLIN and BOULDER, Colorado, June 22, 2020
– Combination Therapy Resulted in Durable, Dose-Dependent Antitumor Efficacy in a Preclinical Model of Colon Cancer –
DUBLIN and BOULDER, Colorado, June 22, 2020 /PRNewswire/ -- Alkermes plc (Nasdaq: ALKS) and Clovis Oncology, Inc. (Nasdaq: CLVS) today announced positive preclinical data from a study designed to evaluate the combination potential of ALKS 4230, Alkermes' investigational engineered interleukin-2 (IL-2) variant immunotherapy, with lucitanib, Clovis' investigational angiogenesis inhibitor. The data will be presented during a poster session at the American Association for Cancer Research (AACR) Virtual Annual Meeting II, taking place June 22-24, 2020.
The study evaluated the antitumor efficacy and mechanism of action of mALKS 4230, a mouse ortholog of ALKS 4230, and lucitanib as monotherapies and in combination in a preclinical syngeneic mouse model of colon cancer. The combination of mALKS 4230 with lucitanib resulted in dose-dependent, durable complete responses (absence of any detectable tumor) and enhanced survival compared with monotherapy treatment with mALKS 4230 and lucitanib.
"Combining treatments with complementary mechanisms may offer synergistic clinical benefit and expand treatment options for a broader set of patient populations," said Craig Hopkinson, M.D., Chief Medical Officer and Executive Vice President of Research & Development at Alkermes. "These compelling preclinical data provide a foundational rationale to further explore novel combination options, such as an angiogenesis inhibitor, for ALKS 4230, with the goal of bringing improved therapeutic outcomes to patients across multiple tumor types."
Key findings presented in the poster include the following:
A virtual poster titled, "The Combination of a Mouse Ortholog of ALKS 4230, a Selective Agonist of the Intermediate-Affinity IL-2 Receptor, and the Angiogenesis Inhibitor Lucitanib Enhances Antitumor Activity," along with a pre-recorded audio presentation by Dr. Jared Lopes, Principal Scientist, Alkermes will be available on the AACR website at https://www.aacr.org/meeting/aacr-annual-meeting-2020/.
About ALKS 4230
ALKS 4230 is an investigational, novel, engineered fusion protein comprised of modified interleukin-2 (IL-2) and the high affinity IL-2 alpha receptor chain, designed to selectively expand tumor-killing immune cells while avoiding the activation of immunosuppressive cells by preferentially binding to the intermediate-affinity IL-2 receptor complex. The selectivity of ALKS 4230 is designed to leverage the proven anti-tumor effects of existing IL-2 therapy while mitigating certain limitations.
Lucitanib is an oral, potent inhibitor of the tyrosine kinase activity of vascular endothelial growth factor receptors 1 through 3 (VEGFR1-3), platelet-derived growth factor receptors alpha and beta (PDFGRα/β) and fibroblast growth factor receptors 1 through 3 (FGFR1-3). Emerging clinical data support the combination of angiogenesis inhibitors and immunotherapy to increase effectiveness in multiple cancer indications. Angiogenic factors, such as vascular endothelial growth factor (VEGF), are frequently up-regulated in tumors and create an immunosuppressive tumor microenvironment. Use of antiangiogenic drugs reverses this immunosuppression and can augment response to immunotherapy.
Lucitanib is an unlicensed medical product.
