DUBLIN, Sept. 4, 2019 /PRNewswire/ -- Endo International plc (NASDAQ: ENDP) today announced that Novitium Pharma, LLC, a partner of Endo's subsidiary Endo Ventures Limited, received approval from the U.S. Food and Drug Administration for a room temperature stable, AB-rated, generic equivalent of Swedish Orphan Biovitrum's Orfadin® (nitisinone capsules).  Endo's operating company Par Pharmaceutical, Inc. expects to distribute the product through specialty pharmacies beginning this month.

"We are proud to continue our tradition at Par of providing high quality, affordable medicines to patients."

"Novitium has a history of impressive development and execution skills and we are pleased to have several products under development with them," said Brandon Rockwell, Senior Vice President of Business Development. "This first time generic approval is another example of Par's strategic investment in business development and execution on first-to-market and first-to-file products."

According to Swedish Orphan Biovitrum, global sales for Orfadin® were approximately $85M over the last four quarters.
