Vaxxinity Demonstrates Target Engagement of Toxic Alpha-Synuclein in Parkinson’s Patients

Globenewswire | July 18, 2023

Vaxxinity, Inc. a U.S. company pioneering the development of a new class of medicines, announced new data from a Phase 1 clinical trial demonstrating that antibodies derived from its investigational immunotherapeutic for Parkinson’s disease (PD), UB-312, slows seeding of alpha-synuclein (aSyn) in cerebrospinal fluid (CSF) of patients with PD as demonstrated using multiple target engagement assays. These data signify that UB-312 has established clear target engagement in PD patient CSF, and provides further validation of Vaxxinity’s platform technology in neurodegenerative disease. “This is a major milestone for Vaxxinity in our quest to help Parkinson’s patients. Our candidate has shown target engagement of the toxic species of alpha-synuclein in patients, demonstrating not only proof of our technology platform, but also proof of the mechanism of our vaccine-derived antibodies specifically engaging with the toxic target in vivo,” said Mei Mei Hu, CEO of Vaxxinity. “Showing target engagement has always been a key challenge to overcome in neurodegeneration, and is of critical importance when demonstrated – a milestone worth celebrating. It is beyond our expectation to see this in our Phase 1 trial. We are endlessly grateful to the patients who participated, and to The Michael J. Fox Foundation and our collaborators for their work on these cutting-edge assays that supported this breakthrough.” UB-312 is designed to target aggregated forms of aSyn, the toxic species that underlies Parkinson’s disease and other synucleinopathies. Last month, Vaxxinity announced clinical data from Part B of its Phase 1 clinical trial of UB-312 demonstrating that UB-312 was well-tolerated and induced anti-aSyn antibody responses in participants with early PD, and that antibodies were detectable in the CSF. As part of this trial, The Michael J. Fox Foundation (MJFF) funded a 2-year collaborative project between Vaxxinity, the Mayo Clinic, and UTHealth Houston to analyze CSF collected from patients, and to conduct exploratory research to characterize the anti-aSyn antibodies produced after UB-312 administration and assess target engagement. Analyses from this and related research yielded insights about the pharmacodynamic effects of anti-aSyn antibodies generated by UB-312 in the Phase 1 trial. UB-312-derived antibodies show preferential binding to aggregated aSyn isolated from patients with PD and Multiple System Atrophy (MSA), as measured by dot blot. Preclinical data published in Alzheimer’s Research & Therapy in 2020 showed similar characteristics of UB-312-derived antibodies. UB-312-derived antibodies successfully demonstrate inhibition of aggregation of aSyn in both a seed amplification assay (SAA) and a protein misfolding cyclic amplification assay (PMCA). These techniques can potentially be used to identify people with PD, and also to measure the treatment response and pharmacodynamic properties of UB-312-derived antibodies from subjects in clinical trials. Importantly, aSyn aggregation was slowed down in CSF samples from PD patients who received UB-312, as compared to those who received placebo, in the Phase 1 trial. Vaxxinity plans to continue analyses of the clinical data as part of the collaborative project with MJFF, in addition to completing other target engagement assays and additional antibody characterization studies for binding kinetics and specificity. Mark Frasier, Ph.D., Chief Scientific Officer of MJFF, commented, “Integration of critical biomarker insight into therapeutic development programs is essential for building confidence in the treatment approach, and for designing informative trials. We’re pleased to support efforts of this kind that can have major impact for people with Parkinson’s disease.” About Parkinson’s Disease Parkinson’s disease (PD) affects approximately one million people in the United States and more than 10 million people worldwide. PD is a chronic and progressive neurodegenerative disorder that affects predominately dopamine-producing (“dopaminergic”) neurons in the substantia nigra area of the brain. While today’s approved products are aimed at providing symptomatic relief, they often produce significant side effects and lose their beneficial effects over time. There are no currently approved disease-modifying therapeutics for PD. Alpha-synuclein (aSyn) is a protein highly expressed in neurons, mostly at presynaptic terminals, suggesting a role in synaptic vesicle trafficking, synaptic functions and in regulation of neurotransmitter release at the synapse. Mutations in the gene encoding aSyn are known to cause or increase the risk of developing PD or dementia with Lewy bodies (DLB) and have been shown to alter the secondary structure of aSyn, resulting in misfolded and aggregated forms of the protein (i.e., pathological forms). While mutations in the aSyn gene are rare, aggregates of aSyn in the form of Lewy bodies (LB) and Lewy neurites are common neuropathological hallmarks of both familial and sporadic PD, suggesting a key role of aSyn in PD neuropathogenesis. Immunotherapy approaches targeting aSyn have been shown to ameliorate aSyn pathology as well as functional deficits in mouse models of PD and are now being investigated in the clinic. About UB-312 UB-312 is a vaccine candidate targeting pathological forms of alpha-synuclein (aSyn) for the disease-modifying treatment and prevention of Parkinson’s disease (PD) and other synucleinopathies. Preclinical data indicated that UB-312 elicits antibodies that preferentially recognize pathological forms of aSyn, and improve motor performance in mouse models of synucleinopathies. Clinical data from the Phase 1 trial indicate that UB-312 elicits antibodies that target aggregated aSyn, and that these antibodies slow the aggregation of alpha-synuclein in the cerebrospinal fluid of patients with PD. The European Medical Agency has granted UB-312 orphan designation for multiple system atrophy.
