Centogene Launches 2-Year Global ROPAD Study to Assess the Genetics of Parkinson’s Disease

ROPAD study, Parkinson's genetics

A two-year, global, observational study that will assess the contribution of genetic factors in the development of Parkinson’s disease has been launched by Centogene, in collaboration with the University of Lübeck.

The new study (NCT03866603), which is called “Rostock International Parkinson’s Disease Study” or ROPAD, seeks to enroll around 10,000 participants worldwide to get a representative snapshot of the genetic variability in a large population of patients with this progressive neurodegenerative disease.

Adult individuals, 18 or older, who have been clinically diagnosed with Parkinson’s disease are eligible to participate in the study, as well as individuals who are family members of a patient with LRRK2 parkinsonism or are at high risk of having the disease.

The main goal of the study is to pinpoint the specific genetic mutations and genes that may be associated with the development of Parkinson’s disease.

The study’s primary outcome will be to assess the number of patients carrying mutations in the LRRK2 gene, in which more than 100 different mutations associated with late-onset Parkinson’s disease have already been identified. The researchers will also assess, as the study’s secondary outcomes, the prevalence of mutations in other genes previously linked to Parkinson’s, such as GBA.

All the genetic analysis will be performed using the CentoCard, Centogene’s proprietary, CE-marked device that has been designed to collect and evaluate dried blood spot samples.

“Centogene is committed to bringing hope to patients and their families by shortening the diagnostic odyssey, and we are proud to be working on this important study that may have vast implications for the future diagnosis and treatment of Parkinson’s disease,” Arndt Rolfs, CEO and founder of Centogene, said in a press release.

“All too often clinical studies do not reflect the ethnic diversity of the world, and this study is unique in that we are working across all ethnicities worldwide and crosschecking the effect of environmental components and individual genetics. We are excited about the contribution that Centogene and our partners are making in discovering deeper insights into Parkinson’s disease genetics,” Rolfs added.

Patients carrying genetic mutations linked to the development of Parkinson’s disease will have the opportunity to participate in the “LRRK2 International Parkinson’s Disease Project (LIPAD),” a study led by professor Christine Klein at the University of Lübeck which is designed to document the frequency of all signs and symptoms of Parkinson’s disease among this particular population.

In addition, patients participating in ROPAD who are carriers of LRRK2 mutations will have the chance to enroll in future clinical studies led by Denali Therapeutics, Centogene’s study partner, which is currently working on a set of new investigational therapies for neurodegenerative disorders.

CENTOGENE, Denali Partnering to Recruit LRRK2 Parkinson’s Patients for Clinical Trials

CENTOGENE, Denali collaboration

CENTOGENE and Denali Therapeutics are teaming up to identify and recruit Parkinson’s disease patients who carry mutations in the LRRK2 gene for future clinical trials, the companies announced.

CENTOGENE will carry out a targeted global recruitment campaign to identify and characterize Parkinson’s patients with LRRK2 mutations  and sequence the LRRK2 gene in this population, using its proprietary CentoCard, a dried blood spot collection kit.

CENTOGENE-recruited patients will participate in clinical trials supporting Denali’s LRRK2 inhibitor therapy program.

Mutations in the LRRK2 gene are one of the most commonly known genetic causes of Parkinson’s disease and usually result in the malfunctioning of lysosomes — special compartments within cells that digest and recycle different types of molecules.

Lysosomal dysfunction is involved in the formation of Lewy body protein aggregates and, therefore, neurodegeneration. LRKK2 regulates the formation and function of lysosomes, which are impaired in Parkinson’s disease and may eventually be restored by inhibiting LRRK2 activity, both in patients with a genetic LRRK2 mutation as well as in those with sporadic Parkinson’s disease.

“Our exclusive collaboration underscores CENTOGENE’s CEO and founder of CENTOGENE, said in a press release. “We believe we can contribute to Denali’s development of disease modifying medicines for patients with Parkinson’s disease. CENTOGENE will help Denali speed up the enrollment of patients in clinical studies for its LRRK2 program.”

CENTOGENE’s dried blood spot collection kit contains a validated procedure to extract high-quality DNA, enzymes, and biomarkers from patients’ blood samples. The technology has several advantages, including ease of handling — the samples are stable once they are dry and can be sent to CENTOGENE by regular mail — no sensitivity over time or to temperature, and cost-effectiveness.

This aids in the delivery of biological samples and makes genetic, enzymatic, and biomarker testing available worldwide.

After the identification of LRRK2 Parkinson’s patients, data will be sent to Denali to potentially recruit patients for its clinical trials testing LRRK2 inhibitor therapies.

Denali’s Parkinson’s pipeline includes two investigational LRRK2 inhibitors currently in the early phase of development, DNL201 and DNL151.

The company’s latest results revealed that DNL201 was safe and well-tolerated by healthy individuals in a Phase 1 clinical trial. The investigational therapy is currently being tested in a dose-escalation Phase 1 study in healthy volunteers in the Netherlands.

“Denali is the first company to conduct clinical trials with LRRK2 inhibitors for the treatment of Parkinson’s disease. This partnership with CENTOGENE is a central part of our global efforts to identify and recruit PD [Parkinson’s disease] patients with a mutation in the LRRK2 gene into our planned clinical studies,” said Carole Ho, MD, chief medical officer and head of development at Denali. “We are impressed with CENTOGENE’s approach and technology and believe that our joint efforts will accelerate the enrollment of PD patients and the completion of our clinical trials.”
