4D pharma plc is a United Kingdom-based pharmaceutical company that focuses on developing Live Biotherapeutic Products (LBPs), which is a drug derived from the human microbiome. The Company's LBPs are biologics based on live organisms, namely single strains of bacteria. It has developed its research to build MicroRx, which is a discovery platform that is able to select those bacteria that have a therapeutic effect in specific diseases. It uses MicroRx to interrogate its library of bacterial isolates to identify LBPs. Its microbiome profiling platform, MicroDx, analyses the microbiome to aid the diagnosis and treatment of patients with its Live Biotherapeutics. Its MicroRx platform has generated a pipeline of development programs in therapeutic areas, including immuno-oncology, gastrointestinal (GI), respiratory, autoimmune and central nervous system (CNS) disease. It is conducting a phase I/II clinical study of MRx-4DP0004 in patients with poorly controlled asthma.
