4D pharma plc's Overview

Total employees75
HeadquartersLeeds
Founded2014

4D pharma plc was a clinical-stage pharmaceutical company renowned for its pioneering work in the research and development of Live Biotherapeutic Products (LBPs), a novel class of medicines derived from the human microbiome. The company's mission was to develop therapies for a wide range of serious unmet medical conditions, including various cancers (e.g., renal cell carcinoma, pancreatic cancer, lung cancer), gastrointestinal disorders, respiratory diseases like asthma, and central nervous system conditions. 4D pharma utilized its proprietary MicroRx® platform to rationally identify and develop single-strain LBP candidates. In June 2022, 4D pharma plc entered administration. Subsequently, in March 2023, its key assets, intellectual property, and certain research personnel were acquired by Armata Pharmaceuticals, integrating 4D's LBP programs and discovery capabilities.

Where is 4D pharma plc's Headquarters?

HQ Function

The Leeds headquarters primarily served as the corporate, administrative, and strategic hub for the company's global operations, including clinical development oversight, financial management, and investor relations before its administration.

Notable Features:

The Leeds office was a modern leased office space within a commercial building, facilitating corporate functions. More notable were its specialized research facilities in Aberdeen, Scotland, equipped for microbiome research, and its GMP-certified manufacturing plant in León, Spain, which were critical to its LBP development.

Work Culture:

Prior to administration, 4D pharma plc likely fostered a highly innovative, research-driven, and collaborative work culture typical of pioneering biotech firms. There was a strong focus on scientific discovery in the microbiome field and the development of novel LBP therapies for unmet medical needs, attracting talent passionate about this cutting-edge area of medicine.

HQ Significance:

The Leeds HQ was significant as the central command for 4D pharma's ambitious strategy to develop and commercialize a new class of therapeutics. It oversaw all corporate functions, R&D direction (in conjunction with Aberdeen), management of extensive clinical trial programs across multiple indications, and its manufacturing scale-up efforts in Spain.

Values Reflected in HQ: The choice of a professional headquarters, coupled with substantial investment in state-of-the-art research facilities in Aberdeen and a dedicated LBP manufacturing plant in León, reflected 4D pharma's commitment to scientific innovation, quality, and its ambition to become a global leader in the Live Biotherapeutics field.

Location:

While headquartered in the UK with key research operations in Scotland and manufacturing in Spain, 4D pharma plc had a global operational footprint. This was primarily driven by its extensive clinical trial programs conducted across multiple countries, including sites in North America (USA, Canada) and Europe. The company also engaged in international collaborations with academic institutions and research organizations, and its investor base was international, reflecting its ambition to bring novel LBP therapies to patients worldwide.
