International Pedatric Stroke Study (IPSS)

Researcher:Hrissanthi Ikonomidou
Sponsor:The Hospital for Sick Children ‘Sickkids’
IRB No:2020-1472
Objective:This is the first multi-center, multi-national study of children with stroke. It seeks to build a network of investigators and high-quality disease data to enable population-based studies, natural history studies, and clinical trials to improve the care of children with stroke.
Description:The International Pediatric Stroke Study (IPSS) was established in 2003 as a multi-center, multi-national clinical research registry. Over the years, it has grown to become a highly successful study vehicle for pediatric stroke research across over 100 institutions worldwide. Today, The IPSS continues to serve as the global data and imaging core for multi-disciplinary pediatric experts who perform international collaborative research in an effort to better understand, prevent, and improve outcomes in pediatric stroke. The robust dataset and cohesive network enable high caliber and ground-breaking research in the field.

Participating sites enroll neonates or children who have had an ischemic stroke or are at high risk of having a stroke into the registry. Participants have their medical and research records reviewed for information about their stroke and abstracted into a secure electronic database called REDCap. The IPSS also provides an attractive imaging platform (through the Stroke Imaging Lab for Children, SILC, housed at SickKids) for sites to share clinically acquired brain images that will complement the clinical dataset. The clinical and imaging datasets will improve our understanding of the processes underlying plasticity and recovery in childhood stroke.

All information captured in the study is de-identified.

This study does not require any interventions or additional visits for research. Two outcome measures are typically administered during a follow-up clinic visit: the Paediatric Stroke Outcome Measure (PSOM) and the Recovery and Recurrence Questionnaire (RRQ). The PSOM is used during clinic visits by the study PI or co-investigator; the RRQ is a parental questionnaire that can be completed during clinic visits or by telephone interview for those parents who cannot attend the follow up appointment. Both measures assess neurological function in the following 5 domains: sensory, motor, language, cognition and behavior.

Participating investigators will retain ownership of their own (single-site) data. However, by entering data into the IPSS, co-investigators give implicit permission for the IPSS to analyze the collective dataset. These contributing investigators are recognized through authorship.

Researcher:Kathleen Shannon
Sponsor:Sun Pharma Advanced Research Company Limited (SPARC)
Protocol No:CLR-18-06
IRB No:2020-0457
Objective:To determine if K0706 reduces the rate of progression of early-stage Parkinson’s disease (PD) versus placebo over 40 weeks, as defined by the sum of the MDS-UPDRS (Movement Disorder Society – Unified Parkinson’s Disease Rating Scale) Parts 2 and 3 scores.
Description:This is a study to evaluate the efficacy, safety and tolerability of two doses of K0706 compared to placebo in subjects with early PD who are not receiving dopaminergic therapy. A subset of eligible subjects may participate in a “Biomarker substudy”.

Trial of Parkinson’s And Zoledronic Acid (TOPAZ)

Researcher:Dr. Kathleen Shannon
Sponsor:National Institute of Aging
IRB No.:1928009
Objective:The primary aim of the study is to evaluate the efficacy of a single infusion of zoledronic acid (ZA, 5mg) to reduce the risk of clinical fractures in Parkinson’s Disease or neurodegenerative parkinsonism.
Description:This home-based randomized clinical trial is designed to test the efficacy of ZA-5 mg in Parkinson’s disease (PD) and parkinsonism patients. This trial will also address barriers to treatment of patients with PD and parkinsonism by providing rigorous evidence about whether ZA reduces fracture risk in patients with PD and parkinsonism, simplifying treatment by giving ZA at home without extra medical visits and BMD testing, and overcoming poor persistence with oral therapies because one infusion may prevent bone loss for at least 2 years. The outcome of this trial will demonstrate how a home-based fracture prevention can reach older PD patients who would not otherwise receive treatment to reduce their high risk of fractures.

Patients with PD will be recruited throughout the US by participating neurologists and health networks as well as the Parkinson’s Foundation. Patients may also self-refer to the study. Interested patients can access study information on a study website ( as well as through the Parkinson’s Foundation Helpline. Patients who wish to enroll will be directed to an interactive electronic consent (eConsent). Following eConsent, participants complete a screening questionnaire (to confirm eligibility), followed by a baseline questionnaire. If a participant is determined to be eligible following these steps, they may be scheduled for a Telemedicine assessment to further confirm the PD or parkinsonism diagnosis, unless they have been referred directly from a participating neurologist. If confirmed, the participant will be mailed a supply of vitamin D3 800-1000 IU and instructed to take one vitamin D tablet every day for 2 months. Lastly, a Nurse Home Visit will be scheduled and conducted to confirm final eligibility, randomization, and administration of the study drug, if appropriate. Participants who are randomized will be contacted every 4 months for at least 2 years to determine if they have had any fractures.

Key Eligibility:
  • Men and women age 60 or older
  • Current Parkinson’s Disease or neurodegenerative parkinsonism diagnosis (including progressive supranuclear palsy, multiple system atrophy, cortical basal degeneration, vascular parkinsonism, dementia with Lewy bodies or another form of neurodegenerative parkinsonism)
  • Willing and able to continue in follow-up for at least 2 years
  • Willing and able to provide informed consent
Compensation:Participants who complete a Nurse Home Visit and are randomized will be offered an honorarium (for time and effort) of a $100 gift card, a $50 gift card upon completion of the measures in the 1st year of follow-up (through Month 12), another $50 gift card upon completion of the measures in the 2nd year of follow-up (through Month 24), and a $50 gift card for each completed year of follow-up thereafter, as appropriate.

Enroll-HD: A Prospective Registry Study in a Global Huntington’s Disease Cohort

Researcher:Kathleen Shannon
Sponsor:CHDI Foundation
IRB No.:2021-0877
Objective:The primary objective of Enroll-HD is to develop a comprehensive repository of prospective and systematically collected clinical research data (demography, clinical features, family history, genetic characteristics) and biological specimens (blood) from individuals with manifest HD, unaffected individuals known to carry the HD mutation or at risk of carrying the HD mutation, and control research participants (e.g., spouses, siblings or offspring of HD mutation carriers known not to carry the HD mutation). Enroll-HD is conceived as a broad-based and long-term project to maximize the efficiencies of non-clinical research and participation in clinical research. With 158 active clinical sites in 19 countries, Enroll-HD is now the largest HD database available and is accessible to any interested researcher – visit to learn more.
Description:Enroll-HD is a longitudinal, observational, multinational study that integrates two former Huntington’s disease (HD) registries-REGISTRY in Europe, and COHORT in North America and Australasia-while also expanding to include sites in Latin America. More than 20,000 participants have now enrolled into the study. With annual assessments and no end date, Enroll-HD has built a large and rich database of longitudinal clinical data and biospecimens that form the basis for studies developing tools and biomarkers for progression and prognosis, identifying clinically-relevant phenotypic characteristics, and establishing clearly defined endpoints for interventional studies. Periodic cuts of the database are now available to any interested researcher to use in their research – visit to learn more.
Key Eligibility:Carriers: This group comprises the primary study population and consists of individuals who carry the HD gene expansion mutation.
Controls: This group comprises the comparator study population and consists of individuals who do not carry the HD expansion mutation
These two major categories can be further subdivided into six different subgroups of eligible individuals:
Manifest/Motor-manifest HD: Carriers with clinical features that are regarded in the opinion of the investigator as diagnostic of HD.
Pre-Manifest/-Motor-manifest HD: Carriers without clinical features regarded as diagnostic of HD.
Genotype Unknown: This group includes a first or second degree relative (i.e., related by blood to a carrier) who has not undergone predictive testing for HD and therefore has an undetermined carrier status.
Genotype Negative: This group includes a first or second degree relative (i.e., related by blood to a carrier) who has undergone predictive testing for HD and is known not to carry the HD expansion mutation
Family Control: Family members or individuals not related by blood to carriers (e.g., spouses, partners, caregivers).
Community Controls: Individuals unrelated to HD carriers who did not grow up in a family affected by HD. Data collected from community controls will be used for generation of normative data for sub-studies.
Compensation:You will not receive payment for participating in Enroll-HD. There is also no cost for the research evaluations performed during this research study. Study participants are eligible for a payment to defer the cost of travel.

C3FIT (Coordinated, Collaborative, Comprehensive, Family-based, Integrated and Technology-enabled care): A Comparative Effectiveness Randomized Trial to Improve Stroke Care Delivery

Researcher:Eric Adelman
Sponsor:The Patient Centered Outcomes Research Institute (PCORI)
Protocol No:PCS-2017C3-9081
IRB No:190704
Objective:The current standard of stroke care is the JC-certified CSC/PSC care system, a collection of proven individual processes of care, but a system that lacks coordination for the post-stroke care of patients. The C3FIT trial serves as the opportunity to assess potential impact on patient quality of life and functional outcomes resulting from the improved integration of care provided by the ISPU approach.

C3FIT’s overall goal is to assess if patient outcomes are improved when the CSC/PSC system is supplemented with an Integrated Stroke Practice Unit (ISPU) system of care, a patient-centric model of care involving the patient and caregiver/family that coordinates care from the acute management through the rehabilitation and recovery of the patient.

Description:C3FIT is a pragmatic randomized trial of 18 Joint Commission-certified Comprehensive or Primary Stroke Centers (CSC/PSC) throughout the United States. C3FIT’s specific aim is to assess the superiority of patient-centered outcomes between CSC/PSC and Integrated Stroke Practice Unit (ISPU) models to determine if integrated care models are more effective in nodes of care across the patient recovery continuum. Vanderbilt University Medical Center (VUMC) will guide C3FIT as the Clinical Coordinating Center.
  • ​Age 18+.
  • Clinical diagnosis of acute stroke with brain imaging compatible with intracerebral hemorrhage or ischemic stroke (including normal brain scan)
  • English or Spanish speaking subjects.
  • Patient admitted within 7 days of their index stroke event.
  • Patient is discharged alive and not to hospice care.
  • Patient living at discharge within the geography of recruitment for that C3FIT site.
  • Pre-morbid mRS Rankin score of 0-1.
  • Patient and/or surrogate give consent to participate after an informed consent process.
  • Patients who go to rehabilitation inpatient therapy or other care facilities are eligible, as long as they reside in the geographic are of recruitment and do not go to hospice care.

This drug has been approved by the United States (US) Food and Drug Administration (FDA) for treatment of migraine in adults but is considered investigational in this study because it has not been approved for use in children and adolescents for migraine. For this study, researchers would like to see whether rimegepant is effective and safe for treating migraine in children and adolescents between the ages of 12 and 17 years.
Key Eligibility:History of migraine (with or without aura) for ≥ 6 months before Screening
History of 1 to 8 moderate or severe attacks per month during the 2 months prior to enrollment.
1 or more migraine days requiring treatment during the Observation Phase.
Prophylactic migraine medication is permitted if the dose has been stable for at least 12 weeks prior to the Baseline Visit
Ability to distinguish between migraine and other types of headaches.
Weight ≥ 40 kg at the Screening Visit.
Adequate venous access for blood sampling.
Male and female participants ≥ 12 to < 18 years of age (participants must not reach their 18th birthday before enrollment into the study)
Compensation:Parents/guardians will be paid $50.00 for each completed visit. Children will receive $250.00 for successful eDiary compliance.

CADASIL Consortium

Researcher:Dr. Jane Paulsen
IRB No.:2021-1033
Objective:The objective of the proposed research is to exploit an autosomal dominant vascular dementia as a model to investigate specific features of VCID and to examine interactions with risk factors impacting the aging life course.
Description:The study will enroll a total of 500 participants with a CADASIL family history who have had a genetic test for a NOTCH3 variant. Participants will complete: a clinical interview, a neurological exam, neurocognitive and behavior assessments, MRI, and a blood draw at each study visit. Participants will complete 3 in-person visits in total as part of this study: baseline, visit 2 (18 months after baseline), visit 3 (36 months after baseline). Additional contact will occur by phone, mail, email or the internet and will be referred to as “remote visits”.
Key Eligibility:Inclusion Criteria for CADASIL Participants:
a) Age at least 18 years old
b) positive NOTCH3* genetic testing; or a positive skin biopsy; or willingness to have a NOTCH3 genetic test prior to enrolling and are at-risk for, or diagnosed clinically, with CADASIL
c) willing to commit and complete three in-person visits (baseline and 18-month follow-up and 36-month follow-up) as well as remote visits as needed  by phone, email, mail or internet.
d) All medications will be allowed although the protocol will mandate documentation of medications and our analyses will particularly assess potential impact of medications on outcomes .
e) Able to undergo an MRI scan and blood draw at each visit
f) A study companion who knows the participant well (>= 3 hours/month of contact) and can provide additional information (either remotely or in-person)
g) A functional capacity equivalent to less than 4 on the Modified Rankin Scale.Inclusion Criteria for Healthy Controls (HC)
a) Will meet same criteria as CADASIL participants except are or were at risk for CADASIL but have Negative NOTCH3* genetic testing
Compensation:Participants will be reimbursed for each part of the study they complete.
• Clinical assessment and completion of other study forms (remote and/or in-person): $25 per visit
• MRI scan: $50 per visit
• Blood draws: $25 per visit
Travel, lodging, and meals will either be provided, or participants may receive partial or complete reimbursement. In addition, airport shuttle, parking, mileage, and tolls may be provided or reimbursed to the participant when applicable.
