Panthera Biopartners

Panthera Biopartners is the United Kingdom's largest independent Site Management Organization (SMO), specializing in conducting Phase II and Phase III clinical trials. Founded in July 2019 by Dr. Ian Smith, who previously founded the world's largest SMO, Synexus, and Professor John Lyon, a former global executive at CRO Covance, the company was established to manage clinical trials and patient recruitment for pharmaceutical companies and Contract Research Organizations (CROs).

The company's business model is centered on its network of dedicated clinical trial facilities across the UK, which provide services including trial planning, patient recruitment, data collection, and patient retention. Panthera serves a blue-chip client base that includes ten of the top twelve global pharmaceutical firms and seven of the top CROs. The firm generates revenue by running trials for these clients, addressing the critical industry challenge of efficient patient recruitment. Panthera operates sites in locations such as Glasgow, York, Sheffield, Preston, Rochdale, and Enfield. These sites are equipped with dedicated sample processing laboratories and are staffed by GCP-trained professionals.

Panthera has demonstrated rapid growth, securing its first institutional investment in 2020 and a further £10 million in 2022 to fund expansion across the UK and Western Europe. In August 2025, private equity firm LDC, part of Lloyds Banking Group, made a significant investment to support further international growth, marking a successful exit for previous investors BGF and Gresham House Ventures. The company has achieved significant milestones, including being the top global recruiter in four international studies in 2024. Its therapeutic expertise covers a broad range of areas traditionally managed in primary care, such as vaccines, cardiovascular disease, diabetes, neurology, respiratory medicine, and has expanded into specialist areas like oncology, NASH, and early dementia.
