Orexo commences patent infringement litigation against Sun Pharmaceutical
Orexo AB (OTCQX: ORXOY) has initiated patent infringement litigation against Sun Pharmaceutical Industries in the U.S. District Court for New Jersey. The lawsuit responds to Sun's Abbreviated New Drug Application (ANDA) seeking to market generic versions of Orexo's ZUBSOLV® (buprenorphine and naloxone). Orexo claims that multiple patents protecting ZUBSOLV® are being infringed, with expiration dates from December 2027 to September 2032. This legal action will delay FDA approval of Sun's ANDA for 30 months while the case proceeds. Orexo anticipates increased legal costs primarily in 2021 and 2022.
- Timely legal action could protect ZUBSOLV® market exclusivity until at least December 2027.
- Orexo has a history of successfully defending its patent rights, giving confidence in its litigation strategy.
- Increased legal expenses expected, which could impact financial performance in 2021 and 2022.
UPPSALA, Sweden, Sept. 14, 2020 /PRNewswire/ -- Orexo AB (publ.), (STO:ORX) (OTCQX:ORXOY) today announces it has filed a patent infringement action in the United States District Court for the District of New Jersey with docket number 3:20-cv-12588, against Sun Pharmaceutical Industries Limited, Sun Pharma Global FZE, Sun Pharma Global, Inc., and Sun Pharmaceutical Industries, Inc. (collectively "Sun").
The lawsuit was filed in response to an Abbreviated New Drug Application ("ANDA") filed by Sun with the US Food and Drug Administration ("FDA"). In its ANDA, Sun seeks to market and sell generic versions of Orexo's ZUBSOLV® products, (buprenorphine and naloxone) sublingual tablets (CIII), in the US prior to expiration of the patents listed in FDA's Orange Book. In the lawsuit, Orexo asserts US Patent Nos. 8,470,361; 8,658,198; 8,940,330; 9,259,421 and 9,439,900 against Sun. The patents have expiration dates ranging from December 2027 to September 2032.
Since Orexo timely filed a lawsuit against Sun, FDA is statutorily precluded from approving Sun's ANDA for 30 months, or until a district court decision finds the patents to be invalid or not infringed, whichever occurs first. The 30-month stay period began as of the date Orexo received the notice letter from Sun advising Orexo of their ANDA filing.
Nikolaj Sørensen, Orexo's president and CEO, said: "Today Orexo is much more well prepared to defend the exclusivity of ZUBSOLV® than when we started our previous patent litigation. We successfully defended the exclusivity for ZUBSOLV® in the past and we are well prepared to do so again by enforcing our patent rights against Sun."
Orexo expects increased legal expenses related to the litigation process, with the majority of the expenses expected in 2021 and 2022. The expenses in 2020 are expected to be non-material and any changes to OPEX guidance will be shared in quarterly reports.
