ERG Holding

ERG Holding is the parent company behind Evolution Research Group, an independent U.S. clinical research site and clinical development services organization rather than a therapeutics developer. The business operates a nationwide network of owned and affiliated clinical research units that execute inpatient and outpatient Phase I-IV trials, with particular strength in central nervous system disorders, pain, addiction, sleep, metabolic disease, and other specialized populations. ERG also includes complementary service businesses such as Lotus Clinical Research, a full-service CRO, and CNS Ratings, a rater training and surveillance company. Its value proposition centers on centralized trial operations, harmonized SOPs, specialized facilities, scientific leadership, and access to diverse patient populations to support pharmaceutical and biotechnology sponsors.
