CMT1A Clinical Trial Update: Pharnext PREMIER trial of PXT3003 The PREMIER Trial, which is being conducted in patients with mild-to-moderate CMT1A, is expected to enroll approximately 350 subjects ages 16-65 with a confirmed genetic diagnosis of CMT1A.This International multi-centered pivotal Phase III study will enroll patients at 50 sites worldwide (20 in the US and 5 in Canada) and is set. Clinical trials are being initiated that use the CMT Neuropathy Score (CMTNS), a composite score based on patient symptoms, signs, and neurophysiologic abnormalities, as the primary outcome variable. The sensitivity of the CMTNS or any other score to change over time, as a measure of CMT1A progression, has yet to be determined

Pharnext is planning a new Phase 3 clinical study to further explore the potential of PXT3003 in patients with Charcot-Marie-Tooth disease type 1A (CMT1A).. The decision to launch this new clinical trial was based on recommendations given by the U.S. Food and Drug Administration (FDA) after completing preliminary review and discussion of the pivotal Phase 3 PLEO-CMT study These studies of intramuscular (i.m.) delivery of rAAV1.NT-3 serve as a template for future CMT1A clinical trials with a potential to extend treatment to other nerve diseases with impaired nerve regeneration. Publication types Research Support, N.I.H., Extramural MeSH terms. Unfortunately the trial showed that while the high doses of vitamin C were safe, it did not improve the symptoms nor did it slow the progression of CMT1A on objective tests. The trial did however gather important information on the progression of CMT1A and gained experience in conducting clinical trials for this condition that will be valuable. Charcot-Marie-Tooth disease (CMT) is the most common hereditary neuropathy, and the most common type of this disorder, CMT1A, is caused by overexpression of peripheral myelin protein 22 (PMP22).1 Following publication of the paper by Passage and colleagues in 2004,2 which showed that ascorbic acid improved neuropathic manifestations in the mouse model of CMT1A, clinical trials began to.

CMT Research Foundation Funds Shift Pharmaceuticals to Advance Search for CMT1A Treatment — Shift to Develop and Analyze Novel Series of Drugs Designed to Control Expression of PMP22 Gene Jan 30, 2020; PXT3003 Improves Clinical Outcomes and Stabilizes Disease Progression in CMT1A Patients, Extension Study Shows Jan 17, 202
  2. ation, and medical/developmental history
  3. These promising preclinical studies led to the launch of a clinical development program, that evaluated the potential clinical benefit and safety of PXT3003 in CMT1A patients. PXT3003 has been tested in Phase 2 and Phase 3 studies and an additional Phase 3 clinical trial is currently being planned
  4. Using this approach, Svaren et al, were able to detect an increase in PMP22 expression by 1.5-2 folds in skin biopsies from CMT1A patients when normalized to Schwann cells specific genes. 55 This method can be helpful for CMT1A clinical trials to detect the changes of PMP22 and other CMT1A related genes such as L1 cell adhesion molecule (L1CAM.
  5. CMT1A disease. In preclinical studies, ascorbic acid (AA) was shown to promote myelination in vitro and to decrease PMP22 expression [9-11], and its mechanism of action in the murine peripheral nervous system has recently started to emerge [12]. Following these findings, six clinical trials assessing efficacy and tolerability of 1
  6. It's currently in Phase 2 clinical trials for people with CMT and muscular dystrophy. PXT-3003 and ACE-038 are different as PXT-3003 is intended to reduce PMP-22 protein levels for CMT1A and ACE-083 is intended to regenerate muscle tissue in a variety of neuromuscular disorders. Everything I've read about ACE-083 looks promising but I'm sure it.
  7. The initiation of clinical trials of AA in CMT1A in North America and Europe has led to improved infrastructure for conduct of treatment trials. Nonetheless, partnerships among the pharmaceutical industry, clinical investigators, patient advocacy groups, and private foundations—in addition to enhanced levels of governmental funding of.

  4. CMT1A is a conventional prototype of a myelin disease by histological and electrophysiological criteria but at the same time manifests a clinical phenotype typical of a length-dependent neuropathy resulting from preferential distal axonal loss. 24,25 Our previous studies, along with others have shown that axonal pathology in demyelinating.

CMT1A Research Breakthrough! - Charcot-Marie-Tooth Associatio

Onapristone clinical trials have never been conducted in CMT1A due to severe side effects observed in cancer patients under this drug . A clinical trial (NCT02600286) was conducted in 2015 with ulipristal acetate (EllaOne ® ), another anti-progesterone drug that is already available in the market, claiming the possibility for EllaOne ® to. Sixteen patients with CMT1A were evaluated by spirometry, maximal expiratory and maximal inspiratory pressures (MEP, MIP), polysomnography, phrenic nerve compound muscle action potential (CMAP), and ultrasonography (roots C3,C4,C5 and phrenic nerves). Clinical disability was measured with Charcot-Marie-Tooth neuropathy score (CMT-N

Pivotal Phase 3 Trial of PXT3003 to Begin CMT1A Patient

Charcot-Marie-Tooth disease (CMT) is a spectrum of nerve disorders named after the three physicians who first described it in 1886 — Jean-Martin Charcot and Pierre Marie of France and Howard Henry Tooth of the United Kingdom. The term CMT is regarded as being synonymous with hereditary motor sensory neuropathy (HMSN) 3. clinicaltrials.gov Identifier. Title. Drugs. NCT04762758. Phase III Trial Assessing the Efficacy and Safety of PXT3003 in CMT1A Patients. Baclofen (DB00181) Naltrexone (DB00704) Sorbitol (DB01638 To better understand the effects of CMT1A in the respiratory function, in this study, we correlated the respiratory condition with clinical status, phrenic nerve conduction studies, and ultrasonography of this nerve and of the cervical roots. The reduction of respiratory pressures was the most common abnormality, as already described [19-21. Clinical and electrophysiological evaluation of patients with CMT1A, as shown above, has demonstrated the presence of distal weakness, atrophy and sensory loss. To determine which of these clinical signs and symptoms are the major cause of patients' disability, we estimated disability using an AI in which a score of 0 indicated no disability PXT3003 was initially studied in humans in a randomized Phase II study looking at three dosing levels compared to placebo. 10 11 The clinical trial enrolled 80 patients with mild to moderate CMT1A and followed them for a year. Patient improvement was gauged using the Charcot-Marie-Tooth Neuropathy Score (CMTNS) and the Overall Neuropathy.

Despite the requirement for ascorbic acid (vitamin C) for myelination of Schwann cells in vitro and its benefits in an animal model of the demyelinating disorder Charcot-Marie-Tooth neuropathy 1A (CMT1A), clinical trials of vitamin C in CMT1A patients were disappointing. This week, the disconnect has been bridged by a study of the ascorbic acid. 2014), and occurs earlier than in CMT1A. Clinical heterogeneity observed in CMT2A has been attributed in part to the different functional impact of multiple implicated MFN2 mutations: GTPase and coiled-coiled domain mutations tend to induce more severe and early onset disease whereas mutations in th Background: CMT1A is the most common inherited peripheral neuropathy, affecting approximately 1:5,000 people irrespective of ethnic background or gender.

Gilbert syndrome is a liver disorder that impairs the body's ability to process bilirubin, a substance made when old red blood cells are broken down. This leads to fluctuating levels of bilirubin in the blood, sometimes causing levels to be high (hyperbilirubinemia). Most people with Gilbert syndrome do not have symptoms or have mild jaundice.In some cases, jaundice is triggered or made worse. Proximal limb weakness, in addition to classical distal limb involvement, is observed in approximately one third of CMT2A patients (Bombelli et al., 2014), and occurs earlier than in CMT1A.
