Introduction: Krabbe disease (KD) is an autosomal recessive disorder caused by mutations in the galactocerebrosidase (GALC) gene resulting in neuro-inflammation and defective myelination in the central and peripheral nervous systems. Most infantile patients present with clinical features before six months of age and die before two years of age. The only treatment available for pre-symptomatic or mildly affected individuals is hematopoietic stem cell transplantation (HSCT). In the animal models, combining bone marrow transplantation (BMT) with gene therapy has shown the best results in disease outcome. In this study, we examine the outcome of gene therapy alone. Methods: Twitcher (twi) mice used in the study, have a W339X mutation in the GALC gene. Genotype identification of the mice was performed shortly after birth or post-natal day 1 (PND1), using polymerase chain reaction on the toe clips followed by restriction enzyme digestion and electrophoresis. Eight or nine-day-old affected mice were used for gene therapy treatment alone or combined with BMT. While iv injection of 4 × 1013 gc/kg of body weight of viral vector was used originally, different viral titers were also used without BMT to evaluate their outcomes. Results: When the standard viral dose was increased four- and ten-fold (4X and 10X) without BMT, the lifespans were increased significantly. Without BMT the affected mice were fertile, had the same weight and appearance as wild type mice and had normal strength and gait. The brains showed no staining for CD68, a marker for activated microglia/macrophages, and less astrogliosis than untreated twi mice. Conclusion: Our results demonstrate that, it may be possible to treat human KD patients with high dose AAVrh10 without blood stem cell transplantation which would eliminate the side effects of HSCT.

Krabbe disease is an autosomal recessive disorder resulting from defects in the lysosomal enzyme galactocerebrosidase (GALC). GALC deficiency leads to severe neurological features. The only treatment for presymptomatic infantile patients and later-onset patients is hematopoietic stem cell transplantation (HSCT). This treatment is less than ideal with most patients eventually developing problems with gait and expressive language. Several naturally occurring animal models are available, including twitcher (twi) mice, which have been used for many treatment trials. Previous studies demonstrated that multiple injections of AAVrh10-GALC into the central nervous system (CNS) of neonatal twi mice resulted in significant improvements. Recently we showed that one i.v. injection of AAVrh10-GALC on PND10 resulted in normal GALC activity in the CNS and high activity in the peripheral nervous system (PNS). In the present study, a single i.v. injection of AAVrh10-GALC was given 1 day after bone marrow transplantation (BMT) on PND10. The mice show greatly extended lifespan and normal behavior with improved CNS and PNS findings. Since HSCT is the standard of care in human patients, adding this single i.v. injection of viral vector may greatly improve the treatment outcome.

Globoid cell leukodystrophy (GLD) or Krabbe disease is an autosomal recessive disorder resulting from the defective lysosomal enzyme galactocerebrosidase (GALC). The lack of GALC enzyme leads to severe neurological symptoms. While most human patients are infants who do not survive beyond 2 years of age, older patients are also diagnosed. In addition to human patients, several naturally occurring animal models, including dog, mouse, and monkey, have also been identified. The mouse model of Krabbe disease, twitcher (twi) mouse has been used for many treatment trials including gene therapy. Using the combination of intracerebroventricular, intracerebellar, and intravenous (iv) injection of the adeno-associated virus serotype rh10 (AAVrh10) expressing mouse GALC in neonate twi mice we previously have demonstrated a significantly extended normal life and exhibition of normal behavior in treated mice. In spite of the prolonged healthy life of these treated mice and improved myelination, it is unlikely that using multiple injection sites for viral administration will be approved for treatment of human patients. In this study, we have explored the outcome of the single iv injection of viral vector at post-natal day 10 (PND10). This has resulted in increased GALC activity in the central nervous system (CNS) and high GALC activity in the peripheral nervous system (PNS). As we have shown previously, an iv injection of AAVrh10 at PND2 results in a small extension of life beyond the typical lifespan of the untreated twi mice (~40 days). In this study, we report that mice receiving a single iv injection at PND10 had no tremor and continued to gain weight until a few weeks before they died. On average, they lived 20-25 days longer than untreated mice. We anticipate that this strategy in combination with other therapeutic options may be beneficial and applicable to treatment of human patients.

Lexeo Therapeutics Announces Positive Interim Data for LX1001, First-Ever Gene Therapy to Impact the Underlying Genetic Cause of APOE4-Associated Alzheimer’s Disease, at the Clinical Trials on Alzheimer’s Disease (CTAD) Conference

Dose-dependent increase in neuroprotective APOE2 expression in all participants with ongoing durability at 12 months Consistent reductions across CSF tau biomarkers and tau PET in majority of participants LX1001 well tolerated across all dose cohorts with no reports of amyloid-related imaging abnormalities (ARIA) Company to host webcast today at 7:00 AM ET Oct. 30, 2024 -- Lexeo Therapeutics, Inc. (Nasdaq: LXEO), a clinical stage genetic medicine company dedicated to pioneering treatments for genetically defined cardiovascular diseases and APOE4-associated Alzheimer’s disease, today announced positive interim results from the Phase 1/2 study of LX1001 (NCT03634007) for the treatment of APOE4-associated Alzheimer’s disease (AD). Treatment with LX1001 led to dose-dependent increases in APOE2 protein expression and improvements in AD-associated tau biomarkers, measures which have been closely correlated with cognitive outcomes. LX1001 also demonstrated a favorable safety profile with no reports of ARIA1. The data were presented today in a late-breaking oral presentation at the Clinical Trials on Alzheimer’s Disease (CTAD) conference in Madrid, Spain and expand the body of evidence on LX1001 as a potential therapy for the more progressive course of Alzheimer’s seen in APOE4 homozygotes. “APOE4 homozygotes are approximately 15 times more likely to develop Alzheimer’s disease than the general population, have faster disease progression, and have an increased risk of ARIA with currently available therapies that can cause serious complications,” said Dr. Kim Johnson, Division Chief, Memory Disorders at the Department of Neurology of Duke University School of Medicine and a principal investigator in the Phase 1/2 study. “Today’s results suggest the potential of LX1001, which based on available data is well tolerated without reports of ARIA. The study also resulted in notable reductions in tau biomarkers, which suggest a possible effect on Alzheimer’s disease pathology.” LX1001 is an AAVrh10-based gene therapy candidate designed to deliver the protective APOE2 allele into the central nervous system of APOE4 homozygous patients, who have two copies of the toxic APOE4 allele. APOE2 is associated with a significantly lower risk of Alzheimer’s onset and slower disease progression. In the Phase 1/2 study, which completed enrollment in Q4 2023, fifteen patients with mild cognitive impairment (MCI) or mild or moderate AD were dosed with LX1001 in four dose-ascending cohorts. The study’s primary objective was to assess safety and tolerability, with secondary outcomes including cerebrospinal fluid (CSF) APOE2 protein expression and change in tau and amyloid biomarkers. “In light of the rapid progression of Alzheimer’s disease in this population, these data highlight the therapeutic potential of delivering APOE2, which can impact multiple mechanisms of Alzheimer’s disease upstream of any specific pathway and thereby meaningfully alter the devastating course of this complex disease,” said Dr. Sandi See Tai, Chief Development Officer of Lexeo Therapeutics. “These data are highly encouraging and provide clinical evidence of the unique and targeted mechanism of LX1001 to potentially treat Alzheimer’s disease.” The interim Phase 1/2 data include follow-up through 12-months for dose Cohorts 1 through 3 and follow-up through 6-months for dose Cohort 4, demonstrating: CSF APOE2 protein expression in all participants, with dose- and time-dependent increases in expression and durability out to 12 months Stabilization of amyloid pathology in the majority of participants, with minimal change from baseline in Aß42/40 ratio and amyloid PET Consistent reductions across CSF tau biomarkers including CSF T-tau, P-tau181, P-tau2172 and P-tau2312, in over two thirds of participants relative to baseline and natural history Reductions at 6 months in global tau PET3 SUVR in 5 of 6 participants and in regional SUVR in a majority of participants across all brain regions Participants with moderate AD (n=4) generally demonstrated the most improvement across various biomarker endpoints Four SAEs were reported, with three deemed unrelated to treatment and one event of mild-moderate sensorineural hearing loss assessed as possibly related to treatment with repeat audiometry pending. The Company has initiated engagement with FDA on these data and expects to provide an update on regulatory interactions and further LX1001 development plans in 2025. Lexeo will host a webcast today at 7:00 AM ET to review these data and next steps for the program. To register for and access the conference call and webcast presentation, please visit https://ir.lexeotx.com/news-events/events. The webcast presentation includes slides with further analysis of the LX1001 interim data. The on-demand webcast presentation may be accessed under the News & Events tab in the Investors section of the Company’s website, and a replay will be available following the presentation. LX1001 is an AAVrh10-based gene therapy candidate for the treatment of APOE4-homozygous Alzheimer’s disease. Individuals homozygous for APOE4, an allele of the gene APOE, are approximately 15 times more likely to develop Alzheimer’s disease than the general population, and it is estimated that there are approximately 900,000 APOE4 homozygous patients with Alzheimer’s disease in the United States. Conversely, individuals homozygous for the APOE allele APOE2 are 40% less likely to develop Alzheimer’s disease than the general population. LX1001 is designed to express the protective APOE2 gene in the central nervous system of APOE4 homozygous patients, potentially slowing or halting the progression of Alzheimer’s disease. LX1001 has been granted Fast Track designation by the FDA. Lexeo Therapeutics is a New York City-based, clinical stage genetic medicine company dedicated to transforming healthcare by applying pioneering science to fundamentally change how genetically defined cardiovascular diseases and APOE4-associated Alzheimer’s disease are treated. Using a stepwise development approach, Lexeo is leveraging early proof-of-concept functional and biomarker data to advance a pipeline of cardiovascular and APOE4-associated Alzheimer’s disease programs. 1 Amyloid-related imaging abnormalities (ARIA) refer to MRI findings observed in patients receiving anti-amyloid therapies for Alzheimer’s disease. ARIA is most commonly observed as brain swelling and/or microhemorrhages and has a higher incidence in patients who are APOE4 allele carriers. 2 CSF P-tau217 and P-tau231 collected only in Cohorts 2, 3 and 4; all Cohort 4 samples, including 6 month and 12 month, pending analysis 3 Tau PET performed only in Cohorts 3 and 4; Cohort 4 12-mth visits pending analysis The content above comes from the network. if any infringement, please contact us to modify.

uniQure Announces Dosing of First Patient in Phase I/II Clinical Trial of AMT-162 for the Treatment of SOD1-ALS

LEXINGTON, MA, USA and AMSTERDAM, The Netherlands I October 15, 2024 I uniQure N.V. (NASDAQ: QURE), a leading gene therapy company advancing transformative therapies for patients with severe medical needs, today announced that the first patient has been dosed in the Phase I/II clinical trial of AMT-162 for the treatment of amyotrophic lateral sclerosis (ALS) caused by mutations in superoxide dismutase 1 (SOD1), a rare, inherited and progressive motor neuron disease. EPISOD1 is a Phase I/II multi-center, open-label trial being conducted in the United States with three dose-escalating cohorts assessing the safety, tolerability and exploratory signs of efficacy of AMT-162 in individuals with SOD1-ALS. “We are pleased to announce the first patient dosing of AMT-162, our investigational gene therapy for the treatment of SOD1-ALS, a debilitating, degenerative and fatal disease,” stated Walid Abi-Saab, M.D., chief medical officer of uniQure . “The start of this trial marks the advancement of our third gene therapy program into the clinic with this trial design, continuing our goal of rapidly generating proof-of-concept data using well-established biomarkers in order to bring treatments to patients as quickly as possible. We believe our novel AAV-based gene therapy candidate can deliver on the convenience of one-time dosing with the potential for a differentiated efficacy profile that is needed for such a devasting disease.” AMT-162 is an investigational AAVrh10-based gene therapy that expresses a miRNA designed to knock down the expression of the mutated SOD1 protein. Patients with SOD1-ALS express a misfolded SOD1 protein. This misfolded protein is toxic to motor neurons causing degeneration which, over time leads to muscle weakness, loss of function and eventually death. AMT-162 may offer a novel one-time, intrathecally administered approach to slowing or halting the progression of SOD1-ALS. AMT-162 has been granted both Orphan Drug status and Fast Track designation by the U.S. Food and Drug Administration. The EPISOD1 Phase I/II clinical trial of AMT-162 will be conducted in the United States. The multicenter, open-label trial consists of three cohorts with up to four patients each receiving a short course of immunosuppression prior to and after an intrathecal infusion of AMT-162. The trial will explore the safety and tolerability of AMT-162 and will assess exploratory signs of efficacy by measuring neurofilament light chain, a biomarker of neuronal damage, and SOD1 protein. There are currently four active sites in the U.S. with plans to activate seven additional sites by the first quarter of 2025. Additional details are available on www.clinicaltrials.gov (NCT06100276). About Amyotrophic Lateral Sclerosis (ALS) caused by mutations in Superoxide Dismutase 1 (SOD1) SOD1-ALS is a rare, progressive and fatal neurodegenerative disease that results in the loss of motor neurons in the brain and spinal cord. As ALS progresses, individuals experience muscle weakness and atrophy causing them to lose the ability to move their arms and legs, speak, swallow and eventually breathe, causing respiratory failure. Based on a 2021 study in Neuroepidemiology, there are an estimated ~170,000 individuals with ALS globally with SOD1 mutations representing 2% within that population. According to the National Institute of Neurological Disorders and Stroke, the average life expectancy for those diagnosed with ALS is three to five years from onset of symptoms. About uniQure uniQure is delivering on the promise of gene therapy – single treatments with potentially curative results. The approvals of uniQure’s gene therapy for hemophilia B – an historic achievement based on more than a decade of research and clinical development – represent a major milestone in the field of genomic medicine and ushers in a new treatment approach for patients living with hemophilia. uniQure is now advancing a pipeline of proprietary gene therapies for the treatment of patients with Huntington’s disease, refractory temporal lobe epilepsy, ALS, Fabry disease, and other severe diseases. www.uniQure.com SOURCE: uniQure
