PE-backed Advarra buys Quorum

Advarra, which is backed by Linden Capital Partners, has acquired Quorum, which helps clinical research clients accelerate research. No financial terms were disclosed.


Columbia, MD (March 7, 2019) – Advarra, a portfolio company of Linden Capital Partners and a premier provider of institutional review board (IRB), institutional biosafety committee (IBC), and research quality and compliance consulting services in North America, is pleased to announce the acquisition of Quorum, one of the most preferred central IRBs in the U.S. and Canada. The transaction also includes Quorum’s research and technology consulting division, Kinetiq. The combined organization is a leading global provider of integrated IRB, IBC, and research and compliance consulting services.

“Quorum is known across the research community for integrity, innovation, regulatory expertise, and client service excellence,” said Pat Donnelly, CEO of Advarra. “Their organizational culture and values are the perfect complement to Advarra, and we look forward to sharing best practices to build altogether better capabilities that serve clients and protect research participants.”

Advarra now offers one of the greatest institutional reaches of any independent IRB, serving well over 3,000 research institutions, hospital systems, and academic medical centers. The collective regulatory expertise and client support resources will also further improve institutional service offerings, especially in light of recent regulatory mandates for single IRB review.

The combined expertise of Advarra Consulting and Kinetiq creates a global organization serving the pharmaceutical industry, biotech firms, device manufacturers, academic centers, health systems, and institutions.

Expert consultants specialize in GxP and compliance consulting, clinical quality assurance, on-demand regulatory guidance, human research protection program (HRPP) solutions, technology compliance, biosafety support, research administration, and more.

“Joining Advarra provides our collective clients with expanded service options and an improved technology platform for an overall more comprehensive and responsive service experience,” said Cami Gearhart, CEO of Quorum. “We are excited to provide the research community with additional integrated solutions for research compliance and human subject protections.”

The combined organization is dedicated to a mutual philosophy to accelerate research through innovative technologies, strategic partnerships, and a commitment to one-touch service excellence. This approach reduces operational costs, streamlines study startup activities, prevents errors and administrative burdens, and saves time for clinical research sponsors, CROs, investigators, and institutions.

The Quorum office located in Seattle will support mutual Advarra customers based on the West Coast, and help bolster existing Advarra locations in Columbia, Md., Cincinnati, Research Triangle Park, N.C., Malvern, Pa., and Aurora, Ont., Canada.

“We are excited to welcome the Quorum organization into the Advarra family. Both companies have a relentless commitment to customer service, and we look forward to continuing that through the combined organization. This acquisition further solidifies Advarra’s position as a leading research compliance platform,” said Tony Davis, Chairman of Advarra and President and Managing Partner at Linden.
