Data Explore Differences between Gene Expression Profiles of Teva’s COPAXONE® and Other Glatiramer Acetate Products
Teva Pharmaceutical Industries Ltd., (NYSE:TEVA) today announced that new scientific data presented at the MS Boston 2014: Joint ACTRIMS-ECTRIMS Meeting reveals differences in the gene expression profile between COPAXONE® (glatiramer acetate injection) and other glatiramer acetate products.
In this research, a human monocyte cell line was stimulated by either COPAXONE® or another glatiramer acetate product from several manufacturers. Differences between the gene expression profiles induced by COPAXONE® and these other glatiramer acetate products were observed upon cell stimulation and subsequently confirmed by a quantitative laboratory test (qRT-PCR).
“Teva believes that this analysis suggests that additional studies are needed in order to ensure that other glatiramer acetate products have a similar biologic effect as COPAXONE®,” said Michael Hayden, M.D., Ph.D., President of Global R&D and Chief Scientific Officer at Teva Pharmaceutical Industries Ltd. He added, “For more than 20 years, Teva has manufactured COPAXONE® through its proprietary manufacturing process to ensure batches meet the same specification standards.”
Ben Zeskind, Ph.D., a co-author and CEO of Immuneering Corporation, the company that conducted the data analysis on Teva’s behalf, said, “This gene expression analysis demonstrates that the other glatiramer acetate products studied may differ from Teva’s COPAXONE® in their effect on pathways that may be related to mechanism of action.”
About The Research
The study, conducted by investigators from both Teva and Cambridge, MA-based Immuneering Corporation, examined stimulated cells from a human monocyte cell line (THP-1) with either branded glatiramer acetate, glatiramer acetates from several manufacturers, or vehicle controls. RNA was extracted and expression profiled at various time points post exposure using Affymetrix Human Genome U133 plus 2.0 chips. Differently expressed genes (adj.p < 0.05 by LIMMA) were identified across different conditions, followed by analysis of pathway enrichment. The expression level of top resulting genes was independently analyzed through qRT-PCR assessment. Teva plans to submit this data for peer-reviewed publication. The data was presented for the first time as a poster presentation on September 11, 2014 at the Joint ACTRIMS-ECTRIMS Meeting.
COPAXONE® (glatiramer acetate injection) is indicated for the treatment of patients with relapsing forms of multiple sclerosis. The most common side effects of COPAXONE® are redness, pain, swelling, itching, or a lump at the site of injection, flushing, rash, shortness of breath, and chest pain. See additional important information at: www.CopaxonePrescribingInformation.com. For hardcopy releases, please see enclosed full prescribing information. COPAXONE® is now approved in more than 50 countries worldwide, including the United States, Russia, Canada, Mexico, Australia, Israel, and all European countries.
Important Safety Information about COPAXONE®
Patients allergic to glatiramer acetate or mannitol should not take COPAXONE®. Some patients report a short-term reaction right after injecting COPAXONE®. This reaction can involve flushing (feeling of warmth and/or redness), chest tightness or pain with heart palpitations, anxiety, and trouble breathing. These symptoms generally appear within minutes of an injection, last about 15 minutes, and go away by themselves without further problems. During the postmarketing period, there have been reports of patients with similar symptoms who received emergency medical care. If symptoms become severe, patients should call the emergency phone number in their area. Patients should call their doctor right away if they develop hives, skin rash with irritation, dizziness, sweating, chest pain, trouble breathing, or severe pain at the injection site. If any of the above occurs, patients should not give themselves any more injections until their doctor tells them to begin again. Chest pain may occur either as part of the immediate postinjection reaction or on its own. This pain should only last a few minutes. Patients may experience more than one such episode, usually beginning at least one month after starting treatment. Patients should tell their doctor if they experience chest pain that lasts for a long time or feels very intense. A permanent indentation under the skin (lipoatrophy or, rarely, necrosis) at the injection site may occur, due to local destruction of fat tissue. Patients should follow proper injection technique and inform their doctor of any skin changes. The most common side effects of COPAXONE® are redness, pain, swelling, itching, or a lump at the site of injection, flushing, rash, shortness of breath, and chest pain. These are not all of the possible side effects of COPAXONE®. For a complete list, patients should ask their doctor or pharmacist. Patients should tell their doctor about any side effects they have while taking COPAXONE®. Patients are encouraged to report negative side effects of prescription drugs to the FDA.
