LONDON—Healthcare public relations powerhouse Chandler Chicco Companies, part of the inVentiv Health group, has agreed to acquire German healthcare communication firms, Haas & Health Partner Public Relations and SanCom Creative Communication Solutions, its long-time partners in the German market.

The two sister firms will join inVentiv Health effective immediately and will add a further 33 staff to CCC’s existing European operations, which currently include a London office that is a leader in the UK healthcare public relations market and a smaller satellite office in Paris. CCC had acquired a 20 percent stake in the two firms in 2008.

Both Haas & Health Partner and SanCom CCS will retain their own brands, and Irene Haas, Ulrich van Gemmern and the rest of the firm’s management teams will also continue in their current roles, reporting to Fiona Hall, managing director of Chandler Chicco Companies Europe. Haas & Health clients include Allergan, Lilly, Janssen-Cilag, and Bayer Consumer Care, among other pharmaceutical industry leaders.

According to Haas and van Gemmern, “In an increasingly globalized marketplace, our clients’ needs are changing. Today’s consolidation with Chandler Chicco Companies allows us to broaden our horizons even further.”

Overall, inVentiv Health Communications has a “super-agency” structure in Europe that includes the company’s advertising, public relations, public policy, market access, medical education, marketing, branding and digital services.
