A hallmark of Parkinson’s disease is the accumulation of misfolded alpha-synuclein that can eventually lead to the formation of protein deposits and progressive neurodegeneration.Parkinson’s disease is the second most common neurodegenerative disorder worldwide. CAMBRIDGE, Mass., Aug. 10, 2020 (GLOBE NEWSWIRE) -- Voyager Therapeutics, Inc. (NASDAQ: VYGR) today reported its second quarter 2020 financial results, program progress and corporate updates. In this trial (Voyager initiated RESTORE-1, a Phase 2, randomized, placebo-surgery controlled, double-blinded, multi-center, clinical trial to evaluate the safety and efficacy of VY-AADC in patients who have been diagnosed with Parkinson’s disease for at least four years, are not responding adequately to oral medications, and have at least three hours of OFF time during the day as measured by a validated self-reported patient diary.The primary endpoint of RESTORE-1 is ON time without troublesome dyskinesia, or good ON time, as measured by self-reported patient diary at 12 months.
Relatively low, but measurable, levels of FXN expression were also observed in the cerebellar dentate nucleus, another area of the CNS that is often affected in Friedreich’s ataxia, and that is often considered difficult to target therapeutically.VY-FXN01 is currently in preclinical development. Once we identify a lead candidate for this program, we plan to complete preclinical studies to evaluate the safety and efficacy of our lead candidate, including studies in a relevant animal model of Friedreich’s ataxia and IND-enabling studies.
(2016) Journal of Neuroscience 36 (49): 12425-12435Parkinson’s disease is the second most common neurodegenerative disorder worldwide. Therefore, the amount of dopamine that is produced from each dose of levodopa medicine may be reduced. Pathological and aggregated tau protein is believed to play a key role in severe CNS diseases. The disease affects approximately 30,000 individuals in the U.S.,Huntington’s disease is a fatal, inherited neurodegenerative disease that results in the progressive decline of motor and cognitive functions and a range of behavioral and psychiatric disturbances. Toggle navigation Currently, there are no approved treatments targeting the underlying cause of the disease and only one drug, tetrabenazine, has been approved for the treatment of the specific motor symptoms of Huntington’s disease.
The median survival is approximately three years, and 90 percent of people with ALS die within five years of symptom onset¹. June 17, 2019 Voyager Therapeutics Announces Restructured Gene Therapy Relationship with Sanofi Genzyme and Portfolio Update. An estimated 20 percent of familial cases can be attributed to mutations in superoxide dismutase 1 gene (SOD1). The trial will also measure non-motor symptoms from the Non-Motor Symptom Scale (NMSS), as well as safety.For more information about the RESTORE-1 clinical trial, including eligibility criteria, please visit Amyotropic Lateral Sclerosis (ALS) is a rare, rapidly progressive, fatal disease characterized by the degeneration of nerve cells in the spinal cord and brain resulting in severe muscle atrophy with loss of the ability to walk and speak,Amyotropic Lateral Sclerosis (ALS) is a rare, rapidly progressive, fatal disease characterized by the degeneration of nerve cells in the spinal cord and brain resulting in severe muscle atrophy with loss of the ability to walk and speak, and premature death. We expect that the first clinical trial of VY-FXN01 will enroll Friedreich’s ataxia patients. FXN expression was normalized as a fold increase relative to FXN expression in a human brain reference sample. The disease affects approximately 30,000 individuals in the U.S., according to the Huntington’s Disease Society of America, with symptoms usually appearing between the ages of 30 to 50, and worsening over a 10 to 25-year period. The levels of FXN expression observed using an AAVrh10 vector were, on average, greater than FXN levels present in normal human brain tissue. The research alliance with CHDI builds upon an earlier partnership between CHDI and Sanofi Genzyme and includes financial support from CHDI to help in the preparation and filing of an FDA investigational new drug application. Most Friedreich’s ataxia patients produce very low levels of the frataxin protein, which, though insufficient to prevent the disease, exposes the patient’s immune system to frataxin, thus reducing the likelihood that the FXN protein expressed by AAV gene therapy would trigger a harmful immune response.We conducted preclinical studies in non-human primates and achieved high FXN expression levels within the target sensory ganglia, or clusters of neurons, along the spinal region following intrathecal injection. Voyager Therapeutics, Inc., a clinical-stage gene therapy company developing life-changing treatments for severe neurological diseases, announced the selection of VY-HTT01, a clinical candidate for the treatment of Huntington’s disease.
