IRB review is where your study takes shape.
WCG's IRB provides expert judgment, designated support, and continuity from submission through determination—so decisions are clear, defensible, and studies advance with confidence.
Your Trusted Partner for IRB Review
Critical decisions made during IRB review determine what happens next, which is why the who behind the review matters as much as the how fast.
Your IRB partner should help you get decisions right early so your study moves forward faster without compromising quality. A board of nearly 200 WCG IRB experts, augmented by one of the largest expert clinical advisory networks, works to ensure the swiftest determination of your protocol and documents.
Accelerate IRB Review for Time-Critical Trials
When a trial can’t wait, IRB+ moves faster–up to 50%–without sacrificing the rigorous oversight your study demands.
Nearly six decades of independent IRB experience.
Now we’re defining what comes next.
The Industry’s Most Transparent and Predictable IRB

Why Your Peers Choose WCG for IRB Review:
Designated Client Team and Continuity
Your study is actively managed from submission through determination by a designated support team that understands your protocol, priorities, and timelines. With proactive guidance, hands-on support, and clear accountability, you gain a partner invested in helping your study move forward.
Predictable Timelines, Proven to Accelerate When Needed
Reliable turnaround times let you plan milestones with confidence and maintain momentum. When timelines are critical, IRB+ is your submission’s fast-pass to WCG’s most experienced reviewers. Move up to 50% faster without changing the rigor, consistency, or quality behind every determination.
Deep Experience Across Sites and Institutions
We bring experience working across a broad footprint of sites and institutions. Deep industry ties let us onboard sites significantly faster, with existing knowledge of their inner workings and SOPs, so you move faster with partners we already know and surface risks earlier.
Human-Centered, Technology-Enabled
Technology should simplify review, not make it harder to navigate. Our re-envisioned IRB management platform, eReview Manager, streamlines submissions, collaboration, and visibility while experienced specialists provide guidance at every step. A partnership, not simply a platform.
Judgment Over Speed Alone
IRB review services are only valuable when teams can trust the decision behind them. WCG combines expert judgment, therapeutic expertise, and proactive guidance to deliver determinations that are clear, defensible, and built to support what comes next.
Built for Complexity
Oncology, rare disease, and emerging modalities require more than process expertise. We’ve seen novel interventions, understand the scientific and operational realities behind complex studies, and help teams navigate challenges before they become delays.
Quality Built Into Every Review
Quality isn’t a checkbox, it’s a standard to deliver work you can trust. WCG’s board was the first central IRB to earn AAHRPP accreditation, with operational rigor backed by ISO 9001-certification, and nearly six decades of measurable cycle time performance.
A Legacy that Shaped Ethical Review
As the pioneer of independent ethical review, our nearly six decades of experience continue to set the standard for how studies are evaluated, bringing the judgment and expertise teams rely on when every decision counts.
