ICON plc, (NASDAQ: ICLR) a world-leading healthcare intelligence and clinical research organisation, has been rated as one of the top-performing contract research organisations (CRO) for phase 1 clinical trials in a benchmarking report from the independent pharmaceutical market research company Industry Standard Research (ISR). ICON outpaced the average phase 1 performance scores of other large CROs, solidifying its position as a premier partner for early phase clinical studies.

The report, based on extensive feedback from 159 industry professionals, underscored ICON’s dominance across a wide range of performance metrics and highlights the company’s unwavering commitment to innovation, operational excellence, and customer satisfaction.

Key highlights from the report include:

• Sponsor satisfaction: For phase 1 research, ICON outperformed all other large CROs claiming the highest overall sponsor satisfaction score of 7.4 on a scale of 1-10.
• Outstanding operational metrics: ICON outperformed the average performance score of other large CROs in all 17 operational metrics, with a considerable lead differential in 14. These metrics are grouped into three categories of critical service capabilities including delivery metrics (such as adhering to project timelines), staff characteristics (like therapeutic expertise), and accessibility metrics (clinic availability, for example).
• Robust brand strength: Across the four brand strength performance metrics of familiarity, leadership, reported recent use, and preference, ICON was the only large CRO to improve its scores across the board compared to ISR’s 2024 iteration of this research, with the largest gains in leadership and preference.
• Consistency of excellence: For six consecutive years, ICON has outperformed the weighted average performance scores of the other large CROs in phase 1 clinical trials, demonstrating sustained excellence and reliability.

“ICON’s strong results in this report reflect the dedication, expertise, and innovation that drive our teams globally,” said Steve Cutler, CEO. “Our consistent leadership in phase 1 clinical trials is a testament to our ability to meet and exceed client expectations, deliver high-quality outcomes, and advance breakthroughs in early-phase development.”
