Heron Therapeutics (NASDAQ: HRTX) has reached a settlement agreement with Mylan Pharmaceuticals, a Viatris company, regarding patent litigation for CINVANTI® and APONVIE® injectable emulsions. The settlement grants Mylan a license to market generic versions of both drugs in the United States starting June 1, 2032, or earlier under certain circumstances.

The patent litigations were initiated by Heron in September 2023 and January 2024 after Mylan sought FDA approval for generic versions before the Heron Patents' expiration in 2035. Both companies will file for dismissal of the pending litigations with the U.S. District Court for the District of Delaware.

Heron Therapeutics (NASDAQ: HRTX) ha raggiunto un accordo di transazione con Mylan Pharmaceuticals, una società di Viatris, riguardo alla controversia sui brevetti per le emulsioni iniettabili CINVANTI® e APONVIE®. L'accordo concede a Mylan una licenza per commercializzare versioni generiche di entrambi i farmaci negli Stati Uniti a partire dal 1° giugno 2032, o prima in determinate circostanze.

Le controversie sui brevetti erano state avviate da Heron nel settembre 2023 e gennaio 2024, dopo che Mylan aveva richiesto l'approvazione FDA per versioni generiche prima della scadenza dei brevetti Heron nel 2035. Entrambe le società presenteranno una richiesta di archiviazione delle cause pendenti presso il Tribunale Distrettuale degli Stati Uniti per il Distretto del Delaware.

Ambas compañías presentarán una solicitud para desestimar las litigaciones pendientes ante el Tribunal de Distrito de los Estados Unidos para el Distrito de Delaware.
