pain studies
sites with pain expertise
ERG sites are led by recognized industry leaders and advisory board veterans who have shaped the field of acute pain and analgesia through hundreds of peer-reviewed articles and conference presentations. In the conduct of advanced acute pain studies, our specialized surgical research teams, including meticulously selected, protocol-trained surgeons and anesthesiologists, excel in executing complex multimodal surgical models. Our staff are extensively trained in applying universal, ERG-specific analgesic methodologies, administering study-specific analgesic scales, controlling environmental expectations, and mitigating clinical variance. Supported by long-standing operative teams and ACLS/PALS/BLS/CITI certifications, ERG delivers unmatched trial consistency across multiple sites with a marked reduction of the placebo effect.


ERG owns and operates fully self-contained, custom-built surgical research centers designed specifically to optimize data integrity in acute and postoperative analgesia trials. Our facilities feature advanced onsite surgical suites that provide sponsors with complete oversight across the entire pre-, intra-, and post-operative continuum. To eliminate environmental noise and mitigate the placebo response, the facility utilizes private patient rooms optimized for both short- and long-term inpatient stays, backed by 24-hour medical coverage, four study-specific nurses’ stations, and protocol-compliant meal services. Every operational detail is built for sponsor confidence, featuring rigid quality assurance protocols, advanced retention strategies, and a secure CLIA-waived lab and pharmacy equipped with double-locked narcotics storage, strict temperature controls, and real-time remote surveillance.
