Charcot-Marie-Tooth Disease clinical trials at University of California Health

4 in progress, 3 open to eligible people

Showing trials for
  • Sphingosine Phosphate Lyase Insufficiency Syndrome (SPLIS)

    open to all eligible people

    This is a prospective longitudinal natural history study with a retrospective cross-sectional arm aimed at determining the natural history of sphingosine phosphate lyase insufficiency syndrome (SPLIS), a recently recognized inborn error of metabolism. The central hypothesis is that age of onset, other disease features, and disease biomarkers will be predictive of quality of life (QOL) and survival in SPLIS patients.

  • Biomarkers in the Hyperbaric Oxygen Brain Injury Treatment Trial (BioHOBIT)

    open to eligible people ages 16-65

    There are no therapeutic agents that have been shown to improve outcomes from severe traumatic brain injury (TBI). Critical barriers to progress in developing treatments for severe TBI are the lack of: 1) monitoring biomarkers for assessing individual patient response to treatment; 2) predictive biomarkers for identifying patients likely to benefit from a promising intervention. Currently, clinical examination remains the fundamental tool for monitoring severe TBI patients and for subject selection in clinical trials. However, these patients are typically intubated and sedated, limiting the utility of clinical examinations. Validated monitoring and predictive biomarkers will allow titration of the dose of promising therapeutics to individual subject response, as well as make clinical trials more efficient by enabling the enrollment of subjects likely to benefit. Glial fibrillary acidic protein (GFAP), neurofilament light chain (NfL) and high sensitivity c-reactive protein (hsCRP) are promising biomarkers that may be useful as 1) monitoring biomarkers; 2) predictive biomarkers in severe TBI trials. Although the biological rationale supporting their use is strong, significant knowledge gaps remain. To address these gaps in knowledge, we propose an ancillary observational study leveraging an ongoing severe TBI clinical trial that is not funded to collect biospecimen. The Hyperbaric Oxygen in Brain Injury Treatment (HOBIT) trial, a phase II randomized control clinical trial that seeks to determine the dose of hyperbaric oxygen therapy (HBOT) that that has the highest likelihood of demonstrating efficacy in a phase III trial. The proposed study will: 1) validate the accuracy of candidate monitoring biomarkers for predicting clinical outcome; 2) determine the treatment effect of different doses of HBOT on candidate monitoring biomarkers; and 3) determine whether there is a biomarker defined subset of severe TBI that responds favorably to HBOT. This proposal will: 1) inform a go/no-go decision for a phase III trial of HBOT by providing adjunctive evidence of the effect of HBOT on key biological pathways through which HBOT is hypothesized to affect outcome; 2) provide evidence to support further study of the first monitoring biomarkers of severe TBI; 3) increase the likelihood of success of a phase III trial by identifying the sub-population of severe TBI likely to benefit from HBOT; 4) create a repository of TBI biospecimen which may be accessed by other investigators. This study is related to NCT04565119

  • Myelin Disorders Biorepository Project

    open to all eligible people

    The Myelin Disorders Biorepository Project (MDBP) seeks to collect and analyze clinical data and biological samples from leukodystrophy patients worldwide to support ongoing and future research projects. The MDBP is one of the world's largest leukodystrophy biorepositories, having enrolled nearly 2,000 affected individuals since it was launched over a decade ago. Researchers working in the biorepository hope to use these materials to uncover new genetic etiologies for various leukodystrophies, develop biomarkers for use in future clinical trials, and better understand the natural history of these disorders. The knowledge gained from these efforts may help improve the diagnostic tools and treatment options available to patients in the future.

  • PXT3003 in CMT1A Patients

    Sorry, in progress, not accepting new patients

    The study will consist of 2 periods: Double-blind Treatment and Open-Label Extension(OLE) Period. -Double-blind Treatment Period - This will be randomized, double-blind, placebo-controlled part of the study which will be conducted in parallel groups, ie,1 group receiving the active treatment (PXT3003) and the other group receiving placebo. Primary endpoint of the study will be assessed at Month 15. -Open-label Extension (OLE) Period - All subjects completing Double-blind Treatment Period will be given an opportunity to enter the OLE Period of the study and receive the active treatment (PXT3003). The duration of the OLE Period will be based on Sponsor discretion, ie, Sponsor intends to keep the study open until the study drug PXT3003 is commercially available. During this period, the long-term safety and efficacy of PXT3003 will be assessed as an exploratory objective. Double-blind Treatment Period Objectives: Primary: To evaluate the efficacy of treatment with PXT3003 (a fixed-dose combination of [RS]-baclofen, naltrexone hydrochloride [HCl], and D-sorbitol) compared to placebo in subjects with Charcot-Marie-Tooth disease type 1A (CMT1A). Secondary: To evaluate the safety and tolerability of PXT3003 treatment in subjects with CMT1A. Exploratory: To characterize the relationship between plasma biomarkers and response to PXT3003 treatment. OLE Period Objective: Exploratory: To evaluate the long-term safety and efficacy of PXT3003.
