25 Clinical Trials for Various Conditions
Examining two strategies as potential adjuvant therapies for Duchenne muscular dystrophy (DMD); aerobic exercise training (to induce adaptations in skeletal muscle and improve cardiovascular health) and tadalafil, an FDA-approved vasodilator (to optimize blood flow and muscle perfusion which is impaired and often overlooked in DMD). Target: improved muscle function, vascular health, and DMD treatment.
This study, supported by Charley's Fund, Inc., is being done to determine if the drug Revatio®(also known as Sildenafil), as compared to placebo (an inactive substance that looks like the study drug, but contains no medication), improves heart function in people with Duchenne Muscular Dystrophy and Becker Muscular Dystrophy (DBMD). In people with DBMD, dystrophin is not present or lacking in heart and muscle. This is associated with abnormalities in an enzyme called "neuronal nitric oxide synthase" or nNOS, and leads to decreases in "cyclic GMP," which is necessary for proper function of those muscles. Revatio blocks an enzyme called phosphodiesterase 5 (PDE5), and helps to restore the normal amounts of cyclic GMP. The purpose of this research is to determine if Revatio is safe for people with DBMD and if it can improve heart function. Hypothesis : PDE5 inhibition, with the use of Revatio, will improve cardiac function in patients with DBMD.
The purpose of this research is (1) to identify disease specific walking-related digital biomarkers of disease severity, and (2) monitor longitudinal changes in natural environments, for extended periods of time, in DMD and SMA.
FLOWER is a completely virtual, nationwide, real-world observational study to collect, annotate, standardize, and report clinical data for rare diseases. Patients participate in the study by electronic consent (eConsent) and sign a medical records release to permit data collection. Medical records are accessed from institutions directly via eFax or paper fax, online from patient electronic medical record (EMR) portals, direct from DNA/RNA sequencing and molecular profiling vendors, and via electronic health information exchanges. Patients and their treating physicians may also optionally provide medical records. Medical records are received in or converted to electronic/digitized formats (CCDA, FHIR, PDF), sorted by medical record type (clinic visit, in-patient hospital, out-patient clinic, infusion and out-patient pharmacies, etc.) and made machine-readable to support data annotation, full text searches, and natural language processing (NLP) algorithms to further facilitate feature identification.
HOPE-3 is a two cohort, Phase 3, multi-center, randomized, double-blind, placebo-controlled clinical trial evaluating the efficacy and safety of a cell therapy called deramiocel (CAP-1002) in study participants with Duchenne muscular dystrophy (DMD) and impaired skeletal muscle function. Non-ambulatory and ambulatory boys and young men who meet eligibility criteria will be randomly assigned to receive either deramiocel or placebo every 3 months for a total of 4 doses during the first 12 months of the study. All participants will be eligible to receive 4 doses of deramiocel for an additional 12 months as part of an open-label extended assessment period. After completion of the first open-label extension (Months 12-24), subjects who have completed Month 24 are eligible to continue onto a Long-Term Open-Label Extension period that will provide treatment with deramiocel until commercial availability, or until sponsor's decision to terminate the trial, or the participant withdraws consent.
The GalaxyDMD study is a global Phase 3, open-label, treatment extension study to evaluate the safety, tolerability, and durability of effect in long-term dosing of edasalonexent in pediatric patients with a genetically confirmed diagnosis of DMD. Patients who completed CAT-1004-201 or CAT-1004-301 or siblings of these boys from 4-12 years of age (up to 13th birthday) will be enrolled. Edasalonexent is an orally administered small molecule that inhibits NF-kB, which is a key link between loss of dystrophin and disease pathology and plays a fundamental role in the initiation and progression of skeletal and cardiac muscle disease in DMD.
The PolarisDMD study is a Phase 3, global study to evaluate the efficacy and safety of edasalonexent in pediatric patients with a genetically confirmed diagnosis of DMD. Male patients from 4-7 years of age (up to 8th birthday) will be enrolled. Edasalonexent is an orally administered small molecule that inhibits NF-kB, which is the key link between loss of dystrophin and disease pathology and plays a fundamental role in the initiation and progression of skeletal and cardiac muscle disease in DMD.
The purpose of this study is to improve the understanding of the treatment goals that a person with Duchenne Muscular Dystrophy (DMD) or the caregiver may be most interested in, based on the severity of the person's disease. Data will be collected by online survey when the participant accepts the study invitation ("RSVP questionnaire") and telephone interview on the functional burden and self-identified treatment goals from the perspective of people with DMD and their caregivers. Interviews will be analyzed to help identify things important to Duchenne families to measure in clinical trials and to inform the selection of key concepts of interest and development of future clinical outcome measures, including observer reported outcomes/patient reported outcomes. The study will be conducted in the United States and will enroll between 45 and 120 participants 11 years or older living with DMD as well as their caregivers. The time commitment for the online survey and the telephone interview is about one hour. It is anticipated that the entire study will be completed within one year.
HOPE-2 is a double-blind clinical trial evaluating the safety and efficacy of a cell therapy called CAP-1002 in study participants with Duchenne Muscular Dystrophy (DMD). Non-ambulatory and ambulatory boys and young men who meet eligibility criteria will be randomly assigned to receive either CAP-1002 or placebo every 3 months for a total of 4 doses during a 12-month period.
This study is a long-term study of ataluren in participants with nonsense mutation Duchenne muscular dystrophy.
This single center open-label pilot study will enroll 15 non-ambulatory children with Duchenne muscular dystrophy at least 8 years of age and who demonstrate pre-clinical cardiomyopathy (defined as a cardiac ejection fraction \>55% with abnormal LV strain by cardiac MRI). They will receive (+)-epicatechin at one of three doses during an 8-week dose-ranging study with assessments at baseline, 2 Weeks, 4weeks, and 8 weeks. The study will determine optimal dosing for future cardiac efficacy studies based on serum / plasma biomarker response using follistatin: myostatin ratio, nitrite/nitrate ratio, cardiac troponins and cardiac BNP. Secondary endpoints will include additional biomarker assessments by SOMAscanTM, cardiac functional evaluations by cardiac MRI (LV strain), and echocardiogram (LV strain by speckle tracking) and measures of strength, range of motion and mobility, and clinical safety assessments. Results of secondary endpoint analysis will be used to refine design of subsequent clinical trials powered to detect changes in clinical outcomes.
The MoveDMD study is a 3-part, Phase 1/2, multi-site study to evaluate the safety, efficacy, pharmacokinetics (PK) and pharmacodynamics (PD) of edasalonexent (also known as CAT-1004) in pediatric patients with a genetically confirmed diagnosis of DMD. Male patients from ≥4 to \<8 years of age will be enrolled. Edasalonexent is an orally administered small molecule targeted to inhibit activated NF-κB, a molecule that is activated from infancy in DMD and which is central to causing muscle damage and preventing muscle regeneration. Data on magnetic resonance imaging of the lower and upper leg muscles, physical function (including timed function tests) and muscle strength will be studied.
We are the missing link in clinical trials, connecting patients and researchers seamlessly and conveniently using a mobile health platform to advance medical research. We make it easy for patients to contribute to research for medical conditions that matter most to them, regardless of their location or ability to travel.
Dystrophinopathy is a disease continuum that includes Duchenne muscular dystrophy, which develops in boys. It is caused by a mutation in the gene for dystrophin, a protein that is important for maintaining normal muscle structure and function. Loss of dystrophin causes muscle fragility that leads to weakness and loss of walking ability. A specific type of mutation, called a nonsense (premature stop codon) mutation is the cause of dystrophinopathy in approximately 10-15 percent (%) of boys with the disease. Ataluren is an orally delivered, investigational drug that has the potential to overcome the effects of the nonsense mutation. The main goal of this Phase 3 study is to evaluate the effect of ataluren on walking ability. The effect of ataluren on physical function, quality of life, and activities of daily living will be evaluated. This study will also provide additional information on the long-term safety of ataluren.
The Finding the Optimum Regimen for Duchenne Muscular Dystrophy (FOR DMD) study will compare three ways of giving corticosteroids to boys with Duchenne muscular dystrophy (DMD) to determine which of the three ways increases muscle strength the most, and which causes the fewest side effects. Using the results of this study, the investigators aim to provide patients and families with clearer information about the best way to take these drugs.
Background: - Duchenne muscular dystrophy (DMD) is a disease in which the muscles are unable to make the protein dystrophin. Without this protein, the muscles become gradually weaker. A new medicine called GSK2402968 is being tested to see if it can help prevent or slow down this loss of muscle strength. In this study, boys with DMD and healthy volunteers will have different types of imaging studies to see which ones provide the best images of the muscles. This information will help researchers use these imaging techniques to test the safety and effectiveness of GSK2402968 and other agents. Objectives: - To test magnetic resonance imaging and ultrasound techniques that can detect changes in muscles of boys with DMD. Eligibility: * Boys who have DMD and are in the GSK2402968 drug test study. * Healthy boys of the same age as the above study participants. Design: * Participants will be screened with a medical history and physical exam. * Healthy volunteers will have one 2-hour visit with three tests. Magnetic resonance imaging (MRI) scans of the skeletal muscles and heart and diaphragm muscles will be carried out. Muscle ultrasound imaging of leg and arm muscles will also be done. Participants should not perform heavy physical activity like school sports or long walks during the week before the visit. * Participants in the GSK2402968 study will have the same series of tests as the healthy volunteers. The tests will be given during the study screening phase. They will be repeated after 3 months and 6 months of receiving the study agent (GSK2402968 or placebo) and at 6 months after stopping the GSK study.
Background: We want to learn more about the relationship between the way families function and how children adapt to having a sibling with Duchenne muscular dystrophy (DMD). What we learn will help us design better interventions for families. Objective: * To learn more about how families with an individual with DMD function. * To learn how siblings adapt in families with an individual with DMD. Eligibility: * One parent and one child, age 13-18, from a family where another child has DMD. * The parent and the child must be able to read and write English. Design: * One parent from each family will complete a survey about how family members communicate and relate with each other. The parent will also answer questions about the behavior of the child without DMD. This survey will take you about 40 minutes to complete. * One child from each family, either a boy or a girl, will also complete a survey. This survey asks about how he/she views him/herself. It also asks about how he/she interacts with peers and family members and how he/she behaves. The survey also asks how satisfied he/she is with how his/her family functions. This survey takes about 30 minutes to finish.
The purpose of this study is to identify new genes responsible for neuromuscular disorders and study muscle tissue of patient with known neuromuscular disease, as well as their family members. We are interested in recruiting many types of neuromuscular disease including; Duchenne muscular dystrophy (DMD), Becker muscular dystrophy (BMD), and limb-girdle muscle dystrophy (LGMD). There are still many patients diagnosed with muscular dystrophy with no causative gene implicated in their disease. Using molecular genetics to unravel basis of these neuromuscular disorders will lead to more accurate diagnosis/prognosis of these disorders which will lead to potential therapies.
To evaluate the efficacy and safety of pamrevlumab versus placebo in combination with systemic corticosteroids administered every 2 weeks in ambulatory participants with Duchenne muscular dystrophy (DMD) (age 6 to \<12 years).
The primary objective of this study is to obtain long term safety data of ataluren in male participants with nonsense mutation dystrophinopathy (who participated and completed a previous Phase 3 study of ataluren \[PTC124-GD-020-DMD {NCT01826487}\]) to augment the overall safety database. Screening and baseline procedures are structured to avoid a gap in treatment between the double-blind study (PTC124-GD-020-DMD) and this extension study. This study may be further extended by amendment until either ataluren becomes commercially available or the clinical development of ataluren in duchenne muscular dystrophy (DMD) is discontinued.
The aim of the proposed research is to compare two commonly used pediatric strength testing measures: handheld myometry (HHM) and CINRG Quantitative Measurement System (CQMS), with the goal of identifying a sensitive and valid tool for measuring muscle strength in children with DMD. The data obtained from this study will be used to make recommendations for strength measurement endpoints in prospective muscular dystrophy trials and provide more reliable and accurate recommendations in the clinic for strength assessment. This study will be performed at six participating sites in the Cooperative International Neuromuscular Research Group (CINRG).
The purpose of this project is to devise instrumented insoles capable of accurately measuring gait at each footfall, over multiple hours in any environment. To achieve high accuracy, the investigators will develop a new learning-based calibration framework. Features will be tested in controlled lab settings 39 during a single visit in people with SMA (13), DMD (13) and healthy controls (13) and in 15 participants in real-life environments.
The objective is to develop and test, through an iterative process, an intervention to address and support the development of infants with a confirmed diagnosis of a neurogenetic disorder with associated developmental delays or intellectual and developmental disabilities. The proposed project will capitalize and expand upon existing empirically based interventions designed to improve outcomes for infants with suspected developmental delays. Participants will be infants with a confirmed diagnosis of a neurogenetic disorder (e.g., fragile X, Angelman, Prader-Willi, Dup15q, Phelan-McDermid, Rhett, Smith Magenis, Williams, Turner, Kleinfelter, Down syndromes, Duchenne muscular dystrophy) within the first year of life and their parents/caregivers. The intervention, called the Parent and Infant Inter(X)action Intervention (PIXI) is a comprehensive program inclusive of parent education about early infant development and the neurogenetic disorder for which they were diagnosed, direct parent coaching around parent-child interaction, and family/parent well-being support. The protocol includes repeated comprehensive assessments of family and child functioning, along with an examination of feasibility and acceptability of the program.
Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.
This study will evaluate the antibiotic gentamicin for treating patients with muscular dystrophy caused by a specific genetic abnormality known as a nonsense mutation. In studies of mice with this type of muscular dystrophy, gentamicin treatment produced positive changes in muscle tissue. Patients with Duchenne or Becker muscular dystrophy caused by nonsense mutations by may be eligible for this 2-week study. Before starting treatment, patients will have evaluations of muscle strength and general well being. Two muscle tissue samples will be taken by needle biopsy, under local anesthetic and sedation. Because of potential risks of hearing loss and kidney toxicity associated with gentamicin, patients will also have a hearing test and blood and urine tests for kidney function before starting treatment. (Currently, gentamicin is commonly prescribed for serious infections of the lungs, heart, and digestive and urinary tracts; adverse effects of hearing loss and kidney toxicity can occur with excessively high drug doses.) Patients will be hospitalized during drug treatment. Gentamicin will be given intravenously (through a vein) once a day for 14 days. Blood samples will be collected daily to monitor drug levels and determine dosage adjustments, if necessary. Urine samples will be collected to assess kidney function. Hearing tests will be done on days 7 and 10. On the last day of the study, hearing, kidney function, and muscle strength will be tested and the results compared with pre-treatment levels. Blood and muscle samples will also be taken again for pre-treatment comparison. Hearing, blood, urine, and muscle strength tests will be repeated one month after treatment ends for comparison with previous results.
