Race secures fifth US patent for Zantrene

Race Oncology (“Race”) is pleased to announce that it has been issued a new patent (US 11,135,201) from the United States Patent and Trademarks Office (USPTO) for its cancer drug, Zantrene® (bisantrene dihydrochloride).

This is Race’s fifth patent granted for Zantrene in the United States. “This latest US patent provides Race with additional protection around the use, formulation and compositions of Zantrene (and related chemical structures) that improve the therapeutic benefit of Zantrene”, said Race’s CEO & Managing Director, Phillip Lynch.

The new patent builds on Race’s existing Zantrene patents granted in the USA in 2018 (US 9,993,460 and US 9,974,774), 2019 (US 10,500,192) and in 2020 (US 10,548,876), further strengthening Race’s IP position for Zantrene.

The patent further expands Race’s IP portfolio in the therapeutic utility of Zantrene (and related chemical structures), in particular – for methods, formulations and compositions that improve the therapeutic efficacy of Zantrene and reduce side effects.
