Invitae's Real-World Ciitizen Data Utilized in Praxis Precision Medicines' PRAX-222 IND Filing
Invitae and Praxis Precision Medicines have successfully utilized Invitae's Ciitizen platform to support Praxis' IND application for PRAX-222, a treatment targeting pediatric patients with SCN2A developmental and epileptic encephalopathy. This marks the platform's first use as a source of real-world data in a regulatory filing. The FDA has cleared the IND application for the initial dose cohort of the PRAX-222 EMBRAVE clinical study, emphasizing the importance of innovative data collection in addressing rare diseases where traditional studies are challenging.
- Successful FDA clearance of IND application for PRAX-222, indicating regulatory advancement.
- Innovative use of Ciitizen platform as a source of real-world data for regulatory submissions.
- Potential to offer a new treatment for pediatric patients with SCN2A developmental and epileptic encephalopathy.
- None.
– First use of Ciitizen platform as source of real-world data in regulatory filing –
SAN FRANCISCO and BOSTON, Sept. 20, 2022 /PRNewswire/ -- Invitae (NYSE: NVTA) and Praxis Precision Medicines, Inc. (NASDAQ: PRAX), today announced that real-world clinical insights from Invitae's Ciitizen platform were utilized as natural history data to support the submission of Praxis' Investigational New Drug (IND) application for PRAX-222 for the treatment of pediatric patients with early-onset SCN2A developmental and epileptic encephalopathy (DEE). Praxis announced earlier this month that the U.S. Food and Drug Administration (FDA) cleared the IND application for the initial dose cohort for the PRAX-222 EMBRAVE clinical study.
For many well-established diseases, natural history studies and other rich data sets are available to support regulatory interactions and IND applications. For many rare diseases, including certain severe genetic pediatric epilepsies such as SCN2A-DEE, natural history studies are not yet available to document the high disease burden and significant unmet medical need. In addition, the usual method of collecting these data by having patients seen at many geographically dispersed sites is cost intensive, time consuming and not well suited to rare disorders. Invitae's Ciitizen platform enables the rapid and comprehensive collection and analysis of medical history data, which supports understanding of the patient population and disease severity, may be used as natural history data for regulatory submissions, and can inform protocol design and inclusion and exclusion criteria for clinical studies.
"The comprehensive real-world clinical evidence generated through Invitae's Ciitizen platform was a critical component to the PRAX-222 IND application, integrating a significant amount of natural history data in a highly efficient manner to help bring PRAX-222 one step closer to SCN2A-DEE patients," said Steven Petrou, Ph.D., co-founder and chief scientific officer of Praxis. "In order to make real progress and offer hope to patients living with SCN2A-DEE and their caregivers, it requires a committed ecosystem and a community willing to consider innovative approaches to drug development. We look forward to our continued partnership with Invitae for PRAX-222 and for other precision medicines targeting rare genetic epilepsies with high unmet need."
The data, collected on behalf of SCN2A-DEE patients or their parents/guardians, is de-identified and shared with their consent, and represents the richest aggregation of real-world clinical evidence for SCN2A-DEE patients. The data generated by Invitae's Ciitizen platform is comprehensive, leveraging the HIPAA right of access to gather full medical records, longitudinally, from all of the patients' sites of care. This approach addresses many of the limitations of other data sources, such as de-identified provider electronic medical record and claims data, that were raised by the FDA in recent draft guidance documents on the use of real-world data in regulatory submissions. This novel data collection and extraction model also addresses many of the logistical, financial and methodological limitations of site-based natural history studies, by rapidly enrolling a diverse and representative sample of patients directly without the need to engage with sites for recruitment and data collection. Additionally, the real-world data set underlying this natural history study provides a unique data collection and sharing model wherein the patients, patient advocacy groups and other researchers all have access to the data collected. Patients have complete access to the records for their own use and are also able to remain involved and informed about the research throughout the study, highlighting the benefits of this unique patient-centered research model. "This is, to my knowledge, the first instance of a patient-mediated medical records platform being utilized as the primary natural history data source for a successful IND filing with the FDA," stated Alexandra Berk, medical affairs director at Invitae. "It's an important development in terms of the FDA's openness to including novel data sources as part of the regulatory process."
"We are thrilled to partner with Praxis and see how our Ciitizen platform's high quality data can move the needle forward for patients living with this rare, genetic epilepsy," said Robert Nussbaum, M.D., chief medical officer of Invitae. "Our goal is to advance the understanding of SCN2A-DEE and other diseases and utilize these data to bring new therapies to market faster. Ciitizen is a compelling platform for rapidly gathering both genotypic and phenotypic data with patient consent and engagement for natural history studies for rare diseases, data that are essential to regulatory processes and for developing new therapies."

PRAX-222 is an ASO designed to selectively decrease SCN2A gene expression, directly targeting the underlying cause of early-seizure-onset SCN2A-DEE to treat seizures and other symptoms in patients with gain-of-function SCN2A mutations. In-vitro studies of PRAX-222 have demonstrated reduction in both SCN2A gene expression and protein levels. In-vivo, PRAX-222 has demonstrated significant, dose-dependent reduction in seizures, improvement in behavioral and locomotor activity and increased survival in SCN2A mouse models, with potential to be the first disease-modifying treatment. PRAX-222 has received Orphan Drug Designation (ODD) and Rare Pediatric Disease Designation (RPD) from the FDA, and ODD from the European Medicines Agency (EMA) for the treatment of SCN2A-DEE. The PRAX-222 program is ongoing under a collaboration with Ionis Pharmaceutics, Inc. (NASDAQ: IONS) and RogCon, Inc.
