Dr. Reddy’s Laboratories Announces the Re-Launch of Its Buprenorphine and Naloxone Sublingual Film after Favorable Ruling in Patent Litigation


Dr. Reddys Laboratories Ltd. ((BSE: 500124) (NSE: DRREDDY) (NYSE: RDY) along with its subsidiaries together referred to as Dr. Reddys) announced today the re-launch of its Buprenorphine and Naloxone Sublingual Film, 2 mg/0.5 mg, 4 mg/1 mg, 8 mg/2 mg, and 12 mg/3 mg, a therapeutic equivalent generic version of Suboxone (buprenorphine and naloxone) sublingual film, in the United States market.

The re-launch comes on the heels of a favorable decision issued by the United States Court of Appeals for the Federal Circuit concluding that Indivior had not shown that it is likely to succeed on its claim that Dr. Reddys product infringes U.S. Patent No. 9,931,305. The Federal Circuits decision vacates the District Courts preliminary injunction that had prohibited Dr. Reddys from selling its generic version of Suboxone (buprenorphine and naloxone) sublingual film. The Federal Circuits decision went into effect yesterday. As a result of the Federal Circuits ruling, Dr. Reddys has resumed shipping of the product.

We are pleased with the decision of the appellate court in Dr. Reddys favor, vacating the preliminary injunction that had prevented Dr. Reddys from continuing to market this important drug to the public, explains Marc Kikuchi, Chief Executive Officer, North America Generics. Dr. Reddys is committed to providing affordable treatment options for opioid use disorder and addiction. We look forward to helping patients and our communities in the United States who are impacted by the opioid epidemic.

In June 2018, the U.S. Food and Drug Administration (USFDA) approved Dr. Reddys Buprenorphine and Naloxone Sublingual Film, in four strengths including 2 mg/0.5 mg, 4 mg/1 mg, 8 mg/2 mg, and 12 mg/3 mg, for sale in the U.S. market. The product was launched immediately after approval, with sales and commercialization activities halted as a result of a court-imposed temporary restraining order (TRO) and preliminary injunction against Dr. Reddys. The TRO and preliminary injunction did not prohibit commercial manufacturing of the product.
