Adelphi Group

What Adelphi Group does

Adelphi Group Ltd is a UK-headquartered pharmaceutical consultancy and professional services provider founded in 1986 and operating from Bollington, Cheshire, with regional offices in London, Boston, Doylestown, Amsterdam, Barcelona, and Boulogne-Billancourt. It is a privately held subsidiary of Omnicom Health Group, itself a division of Omnicom Group Inc. (NYSE: OMC), and operates as a multi-brand services platform spanning real-world evidence generation, health economics and outcomes research (HEOR), market access, strategic market research, and medical communications for global pharmaceutical and healthcare clients.

The group's core technology and intellectual property rest on its proprietary Disease Specific Programmes™, observational study frameworks built over more than 20 years and now covering over 60 therapy areas, which generate reusable real-world datasets for pharmaceutical sponsors. Its delivery is organised through operating subsidiaries including Adelphi Real World (multi-country observational studies and healthcare database analyses), Adelphi Values with sub-brands PROVE (value demonstration, HEOR, pricing and market access) and Patient-Centered Outcomes (PRO/COA instrument development), Adelphi Research (strategic market research), Adelphi IN Healthcare Research (integrated primary research), Adelphi Communications, and acquired brands Excerpta Medica, The Planning Shop, TBWA\Adelphi, and Adelphi Targis.

Commercially, Adelphi operates a project-based professional services model with quote-based pricing tailored to client needs, supported by a 700+ global staff and direct enterprise sales engagement. Go-to-market relies on direct enterprise relationships with pharmaceutical companies across the drug development and commercialisation lifecycle, supplemented by Omnicom Health Group's broader healthcare marketing distribution network, industry conferences (ANTHROPY 2025), thought-leadership white papers, graduate recruitment channels, and charity/community partnerships used for brand visibility rather than direct demand generation.
