C-Path Opens Access to Duchenne Regulatory Science Consortium Database

Database will allow sharing of individual-level data with the goal of accelerating therapy development for Duchenne muscular dystrophy

TUCSON, Ariz., April 22, 2021 — Critical Path Institute (C-Path) announced today that it will open access to the Duchenne Regulatory Science Consortium (D-RSC) database to qualified researchers, through its Rare Disease Cures Accelerator, Data and Analytics Platform (RDCA-DAP®). The D-RSC database includes data from Duchenne muscular dystrophy (DMD) clinical trials, natural history studies and clinical data collections. The contributors of these datasets have given permission for this data to be shared externally to accelerate therapy development for DMD.

DMD is a rare, fatal, genetic neuromuscular disorder that is diagnosed in childhood and primarily affects males. It causes progressive muscle loss, resulting in the loss of the ability to walk, loss of upper body strength, progressive breathing issues, cardiomyopathy and premature death. Although there are medical treatments that may help slow its progression, there is currently no cure for DMD.

C-Path’s RDCA-DAP provides a centralized and standardized infrastructure to support and accelerate rare disease characterization, with the goal of accelerating therapy development across all rare diseases. By sharing this valuable data resource through RDCA-DAP, D-RSC aims to extend and amplify the availability of data to accelerate therapy development for DMD, foster the development of tools to accelerate clinical trials for DMD and help develop a deeper understanding of DMD natural history.

“Individuals living with Duchenne are in urgent need of effective treatments,” explained C-Path’s Chief Science Officer Klaus Romero, M.D., M.S., F.C.P. “With the strength in numbers of data available in the D-RSC database, we believe that opening this platform and making data available to qualified researchers will have a profound effect on expediting the drug development process.”

All data in the D-RSC database have been mapped to current Clinical Data Interchange Standards Consortium (CDISC) Standard Data Tabulation Model (SDTM) structures. Data contained in the D-RSC database are fully de-identified and datasets are integrated, so researchers will not be able to identify participants of the studies and data can be used in aggregate.

D-RSC was formed through collaboration between the Critical Path Institute and Parent Project Muscular Dystrophy. Individuals and companies from industry and academia are members of the consortium, and representatives of the U.S. Food and Drug Administration, European Medicines Agency and the National Institutes of Health have joined the consortium coordinating committee as observers.

Researchers interested in contributing data to D-RSC and/or utilizing the database to advance DMD-related research initiatives can learn more at: https://c-path.org/programs/d-rsc/overview/database-access/ or contact D-RSC Associate Director Ramona Belfioire-Oshan, Ph.D., at rbelfioreoshan@c-path.org.

Critical Path Institute Receives Regulatory Support for Liver Injury Biomarker

pr-c-path-logo

Tucson, AZ — January 22, 2018Critical Path Institute (C-Path) announced today that the European Medicines Agency (EMA) has issued a Letter of Support for measurement of glutamate dehydrogenase (GLDH) as a biomarker of hepatocellular liver injury. The letter was awarded to C-Path’s Predictive Safety Testing Consortium (PSTC) and Duchenne Regulatory Science Consortium (D-RSC) to encourage the further study of serum GLDH for monitoring hepatocellular liver injury.

The letter—in response to data submitted by the PSTC Hepatotoxicity Working Group (HWG) and D-RSC—describes EMA’s thoughts on the value of GLDH and supports further evaluation. In it, EMA encourages PSTC and D-RSC to investigate “the voluntary and complementary use of serum GLDH, in conjunction with currently used biomarkers of liver injury, as a clinical biomarker of liver injury.” EMA also supports PSTC’s generation of additional clinical safety data, and plans for further clinical studies to potentially enable formal qualification of GLDH in the future.

“Many of the proteins currently monitored to evaluate liver safety are also found in muscle tissue,” says Jane Larkindale, D.Phil., Executive Director of D-RSC. “In situations where a patient has underlying muscle injury, such as muscular dystrophies, levels of these enzymes may be high in the absence of liver injury. Monitoring of GLDH levels may allow liver injury caused by novel drugs to be detected in this population of patients.”

D-RSC is dedicated to developing tools to accelerate development of safe drugs for Duchenne, and monitoring safety of such drugs is important. PSTC is dedicated to the development of safety biomarkers, so collaboration between the two C-Path consortia accelerated development of this biomarker.

“At C-Path, we are constantly looking to work in partnership across our many consortia, and the GLDH biomarker qualification presented the perfect opportunity for such a collaboration between PSTC and D-RSC,” says John-Michael Sauer, PhD, Biomarker Program Officer and Executive Director of PSTC.

EMA support encourages the biomarker’s use in both nonclinical and exploratory clinical studies as a marker of hepatocellular liver injury, and indicates that this biomarker has strong potential for use in humans and warrants additional exploration and gathering of data.

Says C-Path President and CEO Martha A. Brumfield, PhD, “The data package submitted to EMA supporting use of this liver-injury biomarker, developed by PSTC and D-RSC in partnership, exemplifies successful cross-consortium collaboration at C-Path, and EMA’s support of this biomarker is a harbinger of future success for both consortia. Developing reliable biomarkers remains one of the most productive methods of aligning and streamlining research and regulatory processes.”

The Letter of Support for this biomarker is posted on the EMA website, and can also be accessed via the C-Path PSTC website.
