Written on Tuesday 31st May 2022

Astorg and Amulet Capital Partners (“Amulet”) today announce that they have signed a binding agreement whereby Astorg will acquire OPEN Health, a leading global provider of scientific communications and market access services to the pharmaceutical industry.

  • OPEN Health is one of the leading global providers of scientific communications and market access services helping pharmaceutical companies to unlock the full potential of their clinical and commercial assets.
  • Astorg will actively support and accelerate OPEN Health’s next phase of growth and innovation, drawing on their extensive experience of investing in the healthcare space.

Established in 2011 and headquartered in London, UK, OPEN Health is a key partner to its customers in helping them develop strategies for evidence generation and data communication by leveraging their extensive scientific knowledge and relentless focus on quality. Together, this approach consistently delivers best-in-class scientific communications, health economics and outcomes research (HEOR) and market access services to an ever-increasing audience.

OPEN Health has more than 1,000 employees in 15 locations and six countries, across North America, Europe and Asia. OPEN Health serves over 170 life sciences customers, including 48 of the top 50 pharmaceutical companies. OPEN Health’s existing management team, led by CEO Rob Barker, will continue to lead the organization, building on a strong track-record of organic growth and strategic acquisitions.

"We are excited to build on the momentum across our business and to continue executing with our new partners at Astorg on a shared long-term vision to bring deep scientific solutions that support our clients in driving positive health outcomes,"
said Rob Barker, CEO, OPEN Health. "We are grateful for the strong partnership of the Amulet team over the last three and a half years and for all that we have accomplished in expanding our industry-leading capabilities across disciplines. We continue to be very well positioned to drive innovation and growth, and we look forward to embarking on this next chapter for OPEN Health."

Building on OPEN Health’s leading service offerings, Astorg will invest in the development of the business across its main existing offerings, and beyond, to continue delivering best-in-class scientific content to OPEN Health’s customer base and help them harness the full value of their most important assets.

"OPEN Health is a very impressive company. We have been following the development of the medical affairs space for a long time as the function evolved from a supportive to a central role and identified OPEN Health as a global leader in the making. We have been impressed with its outstanding reputation and the trust it benefits from its customer base.”
said Judith Charpentier, Partner and Head of Healthcare, Astorg. “We look forward to supporting Rob and the OPEN Health management team in continuing to build a global leading scientific focused medical affairs platform, expanding the platform through both organic initiatives and additional strategic acquisitions”, said Olivier Lieven, Director, Astorg.

Ramsey Frank, President and Managing Partner of Amulet, said, “OPEN Health was built around Amulet’s investment thesis in medical affairs: the current generation of drugs is fundamentally different from prior generations, and these therapies need to be brought to market with the support of high science communications and data analytics. We brought OPEN Health together very intentionally via three acquisitions to create a purpose-built suite of services to meet pharma’s evolving needs.”

Amulet Partner Nick Amigone continued, “We could not be more grateful to Rob Barker and his team for the outstanding job they have done in building a true industry leader.”

The terms of the transaction were not disclosed. The transaction is subject to customary regulatory approvals.
