Stand Up To Cancer ambassador Sonequa Martin-Green, recognised for her role as Sasha Williams in The Walking Dead, stars in the charity's new campaign, urging patients to participate in clinical trials that could help make new treatments available.

The Star Trek: Discovery star commented 'Clinical trials are a fundamental path to progress and the brightest torch researchers have to light their way to better treatments. And if you've been diagnosed with cancer, they may be your brightest ray of hope'.
