Aytu BioPharma Announces FDA Orange Book Listing of Newly Issued Patent for Cotempla XR-ODT(R)

ENGLEWOOD, CO / ACCESSWIRE / March 23, 2022 / Aytu BioPharma, Inc. (NASDAQ:AYTU), a pharmaceutical company focused on developing and commercializing novel therapeutics, today announced that its newly issued US patent No. 11,166,947 for Cotempla XR-ODT® (methylphenidate) extended-release orally disintegrating tablet is now listed in the U.S. Food and Drug Administration (FDA) publication, "Approved Drug Products with Therapeutic Equivalence Evaluations", commonly known as the "Orange Book." The Cotempla XR-ODT patent covers methods of use for the effective pediatric dosing of methylphenidate for the treatment of attention deficit hyperactivity disorder (ADHD).

Cotempla XR-ODT is an orally disintegrating tablet containing methylphenidate and is indicated for the treatment of ADHD in patients 6 to 17 years old. FDA approved the New Drug Application for Cotempla XR-ODT in June 2017. The United States Patent and Trademark Office (USPTO)-issued US patent No. 11,166,947 entitled "Effective Dosing of a Child for the Treatment of ADHD with Methylphenidate" is now listed in the FDA's Orange Book and carries a patent term to at least 2038. The listing of this patent extends the Orange Book patent exclusivity for Cotempla XR-ODT by over five years.

"We are pleased to expand and strengthen our intellectual property protection for Cotempla through the listing of this latest patent in the FDA's Orange Book," commented Josh Disbrow, chief executive officer of Aytu BioPharma. "Our prescription ADHD portfolio continues to grow given the growing need for ADHD medications and the unique clinical profile of both Cotempla XR-ODT and Adzenys XR-ODT as the only orally disintegrating tablets approved to treat ADHD. We are excited to protect this key commercial product through this new patent issuance and look forward to continuing to make Cotempla XR-ODT available for patients who need this important medication."

Patents listed in the Orange Book cover drugs that the FDA has approved and deemed both safe and effective for the general public's use. Inclusion in the book's list of patents can make it easier for drug makers to monitor for new generic drugs that could potentially arrive on the U.S. market and infringe on their patents.
