Multi-Site Validation of Biomarkers and Core Clinical Outcome Measures for Clinical Trials Readiness in CDKL5 Deficiency Disorder
University of Colorado, Denver
Summary
Pathogenic variants in the Cyclin-dependent kinase like 5 (CDKL5) gene cause CDKL5 deficiency disorder (CDD, MIM 300672, 105830), a severe developmental and epileptic encephalopathy associated with cognitive and motor impairments and cortical visual impairment. While capability for disease modifying therapies is accelerating, there is a critical barrier for clinical trial readiness that may result in failure of these therapies, not due to lack of efficacy but due to lack of validated outcome measures and biomarkers. The measures and biomarkers validated here will be adaptable to other developmental and epileptic encephalopathies.
Description
Pathogenic variants in the Cyclin-dependent kinase like 5 (CDKL5) gene cause CDKL5 deficiency disorder (CDD, MIM 300672, 105830) a severe developmental and epileptic encephalopathy (DEE) associated with cognitive and motor dysfunction and cortical visual impairment. Recent data suggest CDD is one of the most common genetic causes of DEE. Work in CDD animal models has demonstrated the ability for disease modification and symptom reversal: worldwide efforts are now underway to develop therapeutic strategies (including gene therapy) to treat and potentially cure CDD. While there are four active c…
