Psychiatry Studies
sites with psychiatric expertise
ERG staff is headed by industry leaders in all aspects of psychiatry. Our clinical raters are certified by industry-recognized psychiatric rating experts, with senior team members bringing more than 20 years of specialized experience to the protocol. Raters provide consistency across studies. Critically, both raters and site staff receive extensive training on mitigating placebo response; training that augments sponsor-provided instruction.


ERG sites have access to a full suite of neuroimaging for psychiatric studies, including magnetic resonance imaging (MRI), and positron emission tomography (PET) scans. ERG has expertise conducting electroencephalography/quantitative electroencephalography (EEG EEG/qEEG) studies in psychiatric subjects, as well as other specialized testing such as ophthalmologic exams, gynecological procedures, and surgical implants.
Onsite staff prepare investigational products for all routes of administration, including compounding, encapsulation, and IV infusion. Sites engage in regular mock dosing to ensure that all time points are met, including pharmacokinetics (PK).
We complement our specialized equipment and staff expertise with rigorous quality reviews by full-time quality assurance and quality control staff to ensure optimal outcomes for your study—and ample inpatient beds to accommodate complex study designs and provide the flexibility to separate populations
The target patient population for psychiatric clinical trials is often misdiagnosed—or even undiagnosed—making these trials challenging to recruit, manage and assess. Sponsors then frequently seek very specific traits, from age and gender to BMI or symptomatology. ERG’s signature patient strategies include sophisticated patient recruitment and retention practices deployed across the entire site network. We begin with large patient databases and local partnerships, then carefully prescreen, screen and enroll to gather the optimal patient cohort for your trial.
