Endo International plc – Ordinary Shares (NASDAQ:ENDP) announced that one of its operating companies, Par Pharmaceutical, has been issued a new patent by the U.S. Patent and Trademark Office (PTO) relating to Vasostrict® (vasopressin injection, USP) 20 units/mL. The PTO has issued to Par U.S. Patent No. 9,375,478, which has an expiration date of January 30, 2035.  Patent No. 9,375,478 has been submitted to the U.S. Food and Drug Administration’s (FDA) Approved Drug Products with Therapeutic Equivalence Evaluations, commonly known as the Orange Book, and will have a submission date of June 28, 2016.

This Orange Book listing requires any Abbreviated New Drug Application (ANDA) applicant seeking FDA approval for a generic version of Vasostrict® prior to expiration of the patent to notify Par of its ANDA filing before it can obtain FDA approval. Any ANDA filer whose application was not received prior to submission of the new patent information would be subject to a 30-month stay of marketing approval by the FDAupon the initiation of Hatch-Waxman litigation by Par against the ANDA filer.

Par’s Vasostrict® is the first and only vasopressin injection, USP, product approved by the FDA. Vasostrict® is indicated to increase blood pressure in adults with vasodilatory shock (e.g., post-cardiotomy or sepsis) who remain hypotensive despite fluids and catecholamines. Under the FDA’s unapproved drugs initiative, Par invested significant time and resources to demonstrate the safety and efficacy of its reformulated and improved Vasostrict® product and to obtain FDA approval. Par continues to invest in its sterile injectables manufacturing facility and has proven to be a reliable supplier of high-quality, high-purity products. (Original Source)
