What Quorum Review does
Quorum Review was a private, for-profit pharmaceutical services company founded in 1992 and headquartered in Seattle, Washington, specializing in independent institutional review board (IRB) services. The firm provided ethical and regulatory oversight for clinical research, serving clinical trial sponsors, contract research organizations, and research institutions. According to market coverage, Quorum Review was positioned as one of the leading players in the Institutional Review Board Systems market alongside Advarra and WCG IRB.
The company is no longer operating as an independent entity. Quorum Review was acquired by Advarra, a strategic operating company that has built a unified IRB model "shaped by the heritage of several leading independent IRBs." The evidence supporting this acquisition includes Advarra's marketing site hosting a dedicated URL campaign parameter ('?campaign=quorum') for IRB services and Advarra's first-party messaging describing consolidation of multiple legacy IRB organizations into one platform. Quorum Review's former client base, reviewer expertise, and review precedent are now channeled through Advarra's portfolio, which spans the CIRBI connected-IRB platform, dedicated coordinator partnerships, IBC and DMC review services, and GxP compliance intelligence.
The available source material is heavily weighted toward Advarra rather than Quorum Review as a standalone business. No Quorum Review-specific revenue figures, pricing, product URLs, headcount trend, or standalone technology stack are disclosed; the firm's identifiable scale signal is its 251–500 employee range, consistent with a mid-sized IRB operation prior to acquisition. Quorum Review's operations now sit within Advarra, which is described as the largest central IRB serving more than 72,000 sites.

Quorum Review competitors and assessment

- WCG IRB: WCG IRB is one of the largest central Institutional Review Boards in the U.S. and a direct competitor to Quorum Review, serving the same biopharma sponsors, CROs, and clinical trial sites with independent ethics review services.
- Copernicus Group IRB: Copernicus Group IRB was another leading independent central IRB serving biopharma and CRO clients with independent ethics and regulatory review, directly comparable to Quorum Review's service offering; it was acquired by WCG.
- Schulman Associates IRB: Schulman (now part of Advarra) was one of the largest independent central IRBs prior to its acquisition and a direct historical peer to Quorum Review in central IRB review for industry-sponsored clinical trials.
- BRANY: BRANY (Biomedical Research Alliance of New York) is an independent IRB providing central ethics review services to sponsors, CROs, and institutions, directly comparable in service scope and customer base to Quorum Review.

Broad incumbents
- Advarra: Advarra is the parent company that acquired Quorum Review and operates a unified IRB model that has absorbed multiple leading independent IRBs; it offers a broader portfolio spanning IRB, IBC, DMC, CTMS, and study collaboration platforms that goes well beyond Quorum's core IRB services.
Emerging players
- Veritas IRB: Veritas IRB is a smaller independent central IRB focused on commercial and academic clinical research review, overlapping with Quorum Review's service scope but at a smaller scale and more limited therapeutic coverage.
Others
- IRBNet: IRBNet (a Forte/Advarra ecosystem component historically) provides IRB protocol submission and management software used by many independent and academic IRBs; it is an enabling technology provider adjacent to Quorum Review's services.
Regional players
- Mass General Brigham IRB: Mass General Brigham operates an academic IRB primarily serving its own investigators and affiliated institutions; while not a direct competitor for industry-sponsored central IRB work, it is comparable as an institutional review board serving clinical research.
