Aytu BioPharma Announces Patent Term Extension for EXXUA(TM)
DENVER, CO / ACCESS Newswire / October 28, 2025 / Aytu BioPharma, Inc. (the "Company" or "Aytu") (Nasdaq:AYTU), a pharmaceutical company focused on advancing innovative medicines for complex central nervous system diseases to improve the quality of life for patients, today announced that the method of use patent (U.S. Patent No. 7,538,116) for EXXUATM (gepirone) extended-release tablets ("EXXUA") has been extended through September 2, 2030 under 35 U.S.C. 156. The patent extension further expands upon the new chemical entity ("NCE") exclusivity period granted by the United States Food and Drug Administration ("FDA"). Gepirone is an NCE, and EXXUA is the first-in-class selective serotonin 5HT1a receptor agonist approved by the FDA for the treatment of major depressive disorder ("MDD") in adults.
"We are very pleased that the EXXUA patent has been granted this five year extension which adds to the exclusivity beyond that normally provided by the NCE approval," commented Josh Disbrow, Chief Executive Officer of Aytu. "Further, we continue to engage in discussions with our partner to expand upon the existing intellectual property through various potential life cycle management approaches, which may extend exclusivity beyond 2030."
"EXXUA is on track to be commercially launched in 2025. Its novel product profile is expected to be an important treatment option to help address the unmet needs of the estimated 21 million Americans affected by MDD."
"Although progress has been made in depression treatments, challenges like treatment-related sexual dysfunction and weight gain remain significant drawbacks for many MDD therapies," Disbrow continued. "We believe EXXUA will be a crucial option for doctors treating the millions of patients with MDD in the United States," Disbrow concluded.

Do not start taking an MAOI for at least 14 days after you have stopped treatment with EXXUA.
EXXUA may cause serious side effects, including:
Changes in the electrical activity of your heart called QT prolongation. QT prolongation can cause irregular heartbeats that can be life-threatening. Your healthcare provider will check the electrical activity of your heart with a test called an electrocardiogram (ECG) and will also do blood tests to check your levels of body salts (electrolytes) before and during treatment with EXXUA. Your healthcare provider may check your electrolytes more often during treatment if you have heart failure, a slow heart rate, abnormal levels of electrolytes in your blood, or if you take other medications that can prolong the QT interval of your heartbeat.
A potentially life-threatening problem called serotonin syndrome can happen when EXXUA is taken with certain other medicines.
Manic episodes may happen in people with bipolar disorder who take EXXUA.
