Company will conduct Phase 3 trial of AMO-02 (tideglusib) in adults to support a future submission for marketing authorization in Type 1 myotonic dystrophy in both adult and pediatric indications. LONDON, May 2, 2024 /PRNewswire/ -- AMO Pharma Limited ("AMO Pharma"), a privately held clinical-stage specialty biopharmaceutical company focusing on rare genetic disorders with limited or no treatment options, today provided an update on plans to advance the clinical development program for AMO-02 (tideglusib), the company's investigational therapy in development for the treatment of Type 1 myotonic dystrophy (DM1), following a recent meeting with the U.S. Food and Drug Administration (FDA). Based on the input from the meeting, AMO Pharma will conduct a Phase 3 clinical trial to assess the efficacy and safety of AMO-02 in adult patients with adult-onset DM1 to support a future submission for marketing authorization for the treatment of DM1 in children, adolescents and adults. Continue Reading REACH-CDM (PRNewsfoto/AMO Pharma Limited) Results from AMO Pharma's previous REACH-CDM Phase 2/3 clinical study (the "REACH-CDM Study") involving children and adolescents with congenital-onset DM1 showed that AMO-02 was generally safe and well tolerated during the study, with no reported severe adverse events (SAEs) related to treatment. The primary and secondary outcome measures based on clinician administered subjective ratings showed an unexpected placebo effect that may have masked some beneficial effects of treatment. Further post hoc analysis as reviewed with the FDA indicates that there is sufficient evidence to support the continued development of tideglusib for the treatment of DM1 with agreement that AMO Pharma will now advance a Phase 3 study in adults with the adult-onset version of DM1. During the meeting, FDA reviewed data from the REACH-CDM Study to assess the efficacy and safety of treatment with AMO-02 in children and adolescents with congenital DM1. The FDA also gave feedback on the design of the new Phase 3 clinical trial for adult patients with adult onset DM1. In this study in adult onset DM1, outcome measures will be similar to those that showed benefit in the REACH-CDM Study. Following discussion with the FDA, AMO Pharma will plan a future submission for approval in children, adolescents and adults with myotonic dystrophy based on a package of safety and efficacy data from the new Phase 3 trial in adults combined with efficacy, pharmacokinetic and safety data from AMO Pharma's REACH-CDM Study. "We are pleased with the outcome of the productive discussions we had with the FDA regarding next steps for AMO-02 and continue to feel strongly that this innovative therapy can represent a significant advance in the treatment of patients with DM1, whether they are children, adolescents or adults," said Alan Rubino, executive chair at AMO Pharma. "We are now focused on progressing a new clinical study in adults with adult-onset DM1. We are very grateful to the FDA and to the patients, families, clinicians and investors who have supported our research thus far and we look forward to working with the community to advance this program as rapidly as possible. We will make an announcement regarding the start date and site locations for the adult onset DM1 study shortly." "The results of the REACH-CDM Study showed measures of efficacy benefit across multiple symptom areas, and we are very excited that this clinical development program will continue to move forward," said Hanns Lochmuller, investigator in the REACH-CDM Study at Children's Hospital of Eastern Ontario, Canada. "We remain very hopeful that this investigational therapy can have a transformative impact on the health of patients living with this ultra-rare, severe muscular dystrophy in the years ahead." About AMO-02 AMO-02 (tideglusib) is an investigational therapy in development for the treatment of DM1 with a dual mechanism disrupting the pathogenic RNA repeat in DM1and inhibiting excess levels of the kinase GSK3β. The REACH-CDM Study was a double-blind, placebo-controlled, randomized study in children and adolescents with congenital DM1 intended to support a future submission for marketing authorization in congenital DM1. The study included 56 participants at leading specialist sites in the US, Canada, New Zealand and Australia. Data associated with functional and objective measures were collected during the study, including motor and muscle assessments (10 meter walk/run, myometry, lip strength and lean muscle mass as assessed by DXA scan), cognitive performance (Peabody Picture Vocabulary Test, NIH Toolbox Picture Sequence Memory Test, NIH Toolbox Dimensional Change Card Sort Test), adaptive (real world) function (Vineland Adaptive Behavior Communication Scale, Vineland Adaptive Behavior Daily Living Scale, Vineland Adaptive Behavior Socialization Scale), bone density (DXA scan) and creatine kinase measurements. In post-hoc analyses more participants showed a positive response following AMO-02 treatment than placebo on 10 of the 12 of these measures. Treatment with AMO-02 was associated with clinically significant improvements in walking and cognition and significant effects on objective biomarkers of muscle and neuronal integrity. AMO-02 also showed significant improvement compared to placebo on a Multi-Domain Responder Index integrating clinically significant responses on measures of ambulation, muscle strength, cognitive performance, activities of daily living and an objective biomarker. Primary analyses of subjective rating assessments showed a placebo effect. Patients from this study and treatment naïve patients with congenital or juvenile onset DM1 are currently being supported in the REACH CDM-X open label extension safety study.

AMO Pharma Announces Collaboration with Population Health Research Institute to Advance Proof of Concept Clinical Trial to Assess Efficacy of Tideglusib in Treatment of Arrhythmogenic Cardiomyopathy

LONDON, Feb. 15, 2024 /PRNewswire/ -- AMO Pharma Limited ("AMO Pharma"), a privately held clinical-stage specialty biopharmaceutical company focusing on rare genetic disorders with limited or no treatment options, today announced a collaboration with Population Health Research Institute (PHRI), a joint institute of McMaster University and Hamilton Health Sciences in Canada, to advance a clinical proof of concept trial to assess the efficacy of AMO-02 (tideglusib), AMO Pharma's investigational oral glycogen synthase kinase 3 beta (GSK3β) inhibitor, in the treatment of genotype positive arrhythmogenic cardiomyopathy (ACM). The study, entitled "Targeted Therapy with Glycogen Synthase Kinase-3 Inhibition for Arrhythmogenic Cardiomyopathy" (TaRGET), will be led by the research team at PHRI and will involve collaboration with multiple organizations in addition to AMO Pharma including the Hearts in Rhythm Organization (HiRO). Enrollment is set to begin in mid-2024 at 20 sites across Canada and will include a total of 120 participants who will be randomized in a 1:1 ratio. "It can be a helpless feeling to carry a gene for ACM and know that, no matter how you live your life, you may someday develop a deadly form of heart disease," said Jason Roberts, scientist at PHRI and TaRGET study principal investigator, adding, "Encouraged by earlier studies in animal models, we are hopeful that tideglusib may serve as an effective treatment that can dramatically improve the health of people living with ACM. The TaRGET trial is a critical first step in evaluating this potential." ACM is a form of genetic heart disease characterized by scarring in the heart muscle. This scarring increases the risk of dangerously fast heart rhythms that can lead to sudden cardiac death (SCD). There are currently no approved medical therapies that have been shown to prevent progression of ACM. An implantable cardioverter defibrillator (ICD) is recommended for prevention of SCD for ACM patients considered at high risk for SCD. In prior research, a high-throughput screen of bioactive compounds against a zebrafish model of ACM identified a small molecule classified as a GSK3β inhibitor that successfully prevented and rescued the phenotype, findings that have subsequently been reproduced in a series of ACM murine models. GSK3β is an enzyme that modulates the activity of a broad spectrum of intracellular signaling pathways, including the canonical Wnt/β-catenin pathway whose suppression has been suggested to exert an important role in ACM pathogenesis. "As we continue to advance our research to assess the potential benefits of AMO-02 in the treatment of myotonic dystrophy, we are very pleased to be supporting this landmark research effort in ACM with the outstanding team at PHRI," said Mike Snape, chief scientific officer at AMO Pharma. "Based on extensive research that highlights the proven MOA of AMO-02 as a clinically safe and well tolerated GSK3β inhibitor, we look forward to progress in advancing this promising program that can bring new hope to people living with ACM and their families in the years ahead. This new data has the potential to build on the cardiac efficacy data previously reported in studies conducted in Duchenne muscular dystrophy by Professor Val Fajardo's team at Brock University."

AMO Pharma Announces Preclinical Data Showing AMO-02 Improves Muscle Function, Glucose Handling and CNS function in Mouse Models of Duchenne Muscular Dystrophy

Findings from research collaboration with Brock University also show improved function in metabolic area and skeletal and cardiac muscle. LONDON, Sept. 19, 2023 /PRNewswire/ -- AMO Pharma Limited ("AMO Pharma"), a privately held clinical-stage specialty biopharmaceutical company focusing on rare childhood-onset neurogenetic disorders with limited or no treatment options, today announced initial preclinical data from a study of the use of the company's investigational therapy AMO-02 in the treatment of Duchenne muscular dystrophy (DMD). In a mouse-model study conducted in collaboration with Brock University, treatment with AMO-02 was associated with improvements in muscle function and glucose handling as well as improvements in cardiac muscle function and CNS function. In January 2023, Brock University and AMO Pharma announced initiation of a research partnership supported by a grant from the Brock-Niagara Validating, Prototyping and Manufacturing Institute (VPMI) to investigate the potential utility of GSK3β inhibitors in the treatment of DMD, a rare genetic disorder characterized by progressive muscle degeneration and weakness. A team of researchers at Brock University led by professors Val Fajardo, PhD, and Rebecca MacPherson, PhD, investigated the effects of the GSK3β inhibitor AMO-02 (tideglusib) and a follow-on compound in the mdx.D2 mouse, a well characterized, naturally occurring murine model of DMD. Studies were conducted with one month of oral treatment initiated at either the start of the myodegenerative phase in mice (six to eight weeks) or at an advanced stage of disease progression (24 to 26 weeks). Assessments during treatment investigated the entire disease phenotype rather than being limited to solely muscle function and biomarker expression. Initial studies showed that unlike chronic glucocorticoid treatment in mdx mice, which can acutely improve muscle function while dampening insulin sensitivity, AMO-02 treatment improved both muscle function and glucose handling and showed improved function in metabolic areas, muscle fat deposition and cardiac muscle. These benefits were seen in both early and late stage mdx mice. An additional study led by Dr. MacPherson examined the effects of AMO-02 treatment on cognitive function, as pathology seen in disorders similar to Alzheimer's disease has been previously detected in mdx mice2. These results showed that short-term treatment with AMO-02 significantly improved cognitive function. "These data are important in several ways, particularly in showing the broad profile of efficacy in the mdx mouse at all stages of the degenerative process. Benefit was seen in multiple organ domains including heart and brain as well as in metabolic function, skeletal muscle, and glucose and fat handling," said Dr. Fajardo. "These studies further reaffirm the strong potential of AMO-02 in treating the muscle damage and weakness that occurs with Duchenne muscular dystrophy and other muscle-wasting conditions, as well as the potential to improve cardiac and skeletal muscle health and function. We look forward to building a larger research collaboration with Brock and extend our gratitude to Drs. Fajardo and MacPherson and their teams for their outstanding work," said Michael Snape, PhD, AMO Pharma Chief Scientific Officer. AMO Pharma also recently announced results from the REACH-CDM clinical study of the investigational therapy AMO-02 in the treatment of children and adolescents with congenital myotonic dystrophy that showed statistically and clinically significant efficacy benefits in multiple areas including cognitive performance, reduction in biomarkers and improvements in walk/run measurements. The company plans to meet with regulators to outline a path forward for the development of AMO-02, including plans for study in patients with adult-onset myotonic dystrophy.
