About Cancer

Cancer is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body. Globally, it is estimated that there were around 18 million new cases in 2018 and that almost 10 million people died of cancer, making it the leading cause of death world-wide. The number of new cancer cases per year is expected to rise to 23.6 million by 2030. The global market for oncology drugs is expected to reach $111.9bn by 2020.

The microbiome has been implicated in cancer treatment and response in a range of clinical settings including standard chemotherapy. The microbiome profile of patients has been demonstrated to drive response to anti-PD-1 therapy in both melanoma and non-small cell lung cancer.

About MRx0518

As both a monotherapy and in combination settings MRx0518 has demonstrated robust efficacy as an immuno-stimulant and anti-tumour agent in multiple tumour models such as breast cancer, renal cell carcinoma and lung cancer. MRx0518 acts on both the innate and adaptive immune system to induce a response mediated by TLR-5.

The Company is investigating MRx0518 across a range of clinical cancer settings in 2019. In collaboration with Merck, Sharpe & Dohme (Merck & Co. Inc), MRx0518 is being evaluated in an open label Phase I/II study of MRx0518 in combination with KEYTRUDA(®) (pembrolizumab) in patients with solid tumours who have failed prior anti-PD-1 therapy. A Phase I randomised, placebo-controlled study of MRx0518 as a monotherapy in a neoadjuvant setting for solid tumours has also commenced.
