Adelphi Worldwide in Macclesfield has acquired The Planning Shop international (TPSi) in London for an undisclosed fee.

TPSi has offices in London and Philadelphia, specialising in providing research and marketing into products for both pharmaceutical and over-the-counter markets.

“We are delighted to welcome TPSi to the Adelphi Group. I have admired their creative skills in developing a unique agency and branded solution-based offer in the global space,” said Stuart Cooper, Adelphi Worldwide’s CEO.

“They complement superbly our research presence across the spectrum, from molecule idea development to tangible brand – delivering the right solution and communication for patients and healthcare professionals. This really strengthens even further our top flight presence as a group in this sector.”

Adelphi is part of the DAS Group of Companies, which is in turn a division of Omnicon Group.
