Health Care Professionals/Laboratory: Clinical Studies

• The utility of the ImmuKnow assay has been well characterized and validated

– Over 650,000 assays run

– 25 prospective and interventional studies in more than 1,000 transplant recipients

– More than 120 clinical studies

• To date, global immune status monitoring has been used to:

– Identify kidney,² liver,¹ lung,^3,4 and heart⁵ transplant patients with low immune
   response, which has the potential to lead to infection

– Define immunologic stability in various solid organ transplant patients^5,6

– Longitudinally assess changes in transplant patients’ immune status, giving
   clinicians an additional tool in treatment optimization decisions^1,5-7

• The ImmuKnow assay is FDA-cleared and reimbursable
