Olatec Therapeutics Awarded a Grant from The Michael J. Fox Foundation in Collaboration With Medical University of Innsbruck to Evaluate Dapansutrile in Animal Models of Parkinson’s Disease Progression

Olatec Therapeutics LLC (Olatec), a leader in the developing class of selective NLRP3 inhibitors, today announced that The Michael J. Fox Foundation for Parkinson’s Research (MJFF) awarded a research grant to evaluate Olatec’s lead molecule, dapansutrile, in preclinical Parkinson’s disease (PD) progression models.

  • The Michael J. Fox Foundation for Parkinson’s Research (MJFF) has awarded a grant from their Therapeutics Pipeline Program to support preclinical research evaluating Olatec Therapeutics’ lead compound, dapansutrile, in Parkinson’s disease (PD)
  • Under this grant Olatec, in collaboration with Dr. Nadia Stefanova (Medical University of Innsbruck), will be studying dapansutrile in both wildtype and transgenic mice with α-synuclein inclusion pathology to assess dapansutrile’s effect on motor symptoms and lowering neuroinflammation and plaque formation
  • PD motor clinical symptoms are thought to arise after substantial loss of the dopamine-producing cells of the substantia nigra; currently, there are no therapeutics that can alter PD progression
  • Dapansutrile has previously been found to protect substantia nigra cells in another PD mouse model

NEW YORK--(BUSINESS WIRE)-- Olatec Therapeutics LLC (Olatec), a leader in the developing class of selective NLRP3 inhibitors, today announced that The The Michael J. Fox Foundation for Parkinson’s Research (MJFF) awarded a research grant to evaluate Olatec’s lead molecule, dapansutrile, in preclinical Parkinson’s disease (PD) progression models. These studies are being initiated in collaboration with researchers at the Medical University of Innsbruck in Austria. The studies will assess dapansutrile’s potential effect as an anti-neuroinflammatory agent, and its pharmacokinetics to confirm validated target engagement in certain transgenic and propagation mouse models. The aim of this collaboration is to accelerate the development of a potential therapeutic intervention that may prevent or mitigate the development of PD’s motor and non-motor symptoms.

PD is a complex neurodegenerative disease marked by motor symptoms and in some cases dementia. Loss of neurons in areas that produce dopamine, particularly the substantia nigra, leads to decline in motor performance. Mounting scientific literature suggests a neuroinflammatory process related to aggregation of α-synuclein protein as a potential driver of these changes. A protein found abundantly in the brain, α-synuclein, typically functions in facilitating communications between neurons; however, misfolded α-synuclein can aggregate into intracellular inclusions (Lewy bodies). Age-related accumulation of tangled α-synuclein protein may initiate or run in parallel to an inflammatory cascade resulting in neuron death. As such, significantly, down regulating neuroinflammatory processes may prevent or slow formation of α‑synuclein aggregation.

When asked about the MJFF grant, Charles Dinarello MD, Olatec SAB Chair, said: “The data we have generated using a standard mouse model of Parkinson’s disease allow us to advance our findings with the models to be used by Dr. Stefanova. Specifically, our current data reveal that dapansutrile’s reduction in brain levels of pro-inflammatory cytokines, IL-1β and IL‑18, results in significant improved locomotion and lower brain levels of the pathologic α-synuclein. We are very pleased to receive this grant from the MJFF and are hopeful the findings will advance us into a clinical trial with dapansutrile in Parkinson’s disease.”

The study, funded by the MJFF grant, will investigate treatment with oral dapansutrile in both an α‑synuclein propagation model in wildtype mice and a transgenic mouse model with upregulated production of full-length human α-synuclein leading to progressive motor deficits. The aim of the study will be to quantify how oral dapansutrile might protect neurons, reduce α-synuclein aggregation and neuroinflammation, and prevent motor deficits. Additionally, the study will evaluate tolerability and pharmacokinetics in the murine system.

Nadia Stefanova MD PhD, the lead investigator on this study, is a professor in the Department of Neurology, Medical University of Innsbruck. Dr. Stefanova is a leader in the field of α-synucleinopathies, which are neurodegenerative diseases characterized by the accumulation of misfolded α-synuclein in brain tissue, including PD, Lewy Body Dementia, and Multiple System Atrophy. Dr. Stefanova’s research focus includes the development of experimental mouse models for therapeutic development as well as the significance of neuroinflammatory responses in disease mechanisms. Commenting on the MJFF grant, Dr. Stefanova said: “We are looking forward to the preclinical investigation of dapansutrile in our α-synuleinopathy models to further advance PD science and investigate the drug’s potential mechanism of action in treating this disease. I am also thrilled to launch our collaboration with Olatec and the lab of Charles Dinarello with the funding support of MJFF, and to work on the preclinical evaluation of dapansutrile for the treatment of PD and related disorders.”

Olatec’s Founder and CEO Damaris Skouras commented: “Olatec is very pleased to be awarded this grant, and to be collaborating with Dr. Stefanova on this important research evaluating dapansutrile in the potential treatment of this debilitating disease with unmet medical need.”

About Parkinson’s disease

Nearly one million Americans are living with PD, and close to 90,000 will be diagnosed this year. Currently, there are no therapeutics that can alter PD disease progression. Patients initially present with complaints of changes in sleep, movement, and speech; worsening physical symptoms are later met with the development of cognitive decline. Medications such as levodopa are palliative, reducing symptom burden but unable to alter disease progression.

About Dapansutrile

Dapansutrile (lab code: OLT1177®) is an investigational small molecule, new chemical entity that specifically binds to and blocks NLRP3 (nucleotide-binding and oligomerization domain [NOD]‑, leucine rich repeat-, pyrin domain-containing 3), the sensor molecule integral in the formation of the NLRP3 inflammasome. Inflammasomes are multiprotein complexes involved in intracellular surveillance of danger signals that trigger an intense inflammatory response, via generation of bioactive IL-1β and IL-18 through caspase-1 activation. Dapansutrile has been shown to prevent the formation of the NLRP3 inflammasome, which in turn inhibits the production of IL-1β and IL‑18. NLRP3 is one of the most characterized inflammasome sensors due to its involvement in a wide range of disorders, including sterile inflammation, infections, and rare genetic autoimmune syndromes. Dapansutrile has been well tolerated and shown to improve clinical outcomes in patients with acute gout flare (see The Lancet Rheumatology) and heart failure (see Journal of Cardiovascular Pharmacology). Dapansutrile has also been observed to have anti-inflammatory properties and other promising activity in a broad spectrum of over 20 preclinical animal models including arthritis, asthma, acute myocardial infarction (AMI), heart failure, contact dermatitis, multiple sclerosis, melanoma, pancreatic and breast cancers, spinal cord injury (SCI), Parkinson’s and Alzheimer’s disease.

About Dapansutrile’s Preclinical CNS Research

Dapansutrile is being studied in multiple models of the central nervous system and neuroinflammation, including: Alzheimer’s disease (AD), spinal cord injury (SCI), multiple sclerosis (MS), and Parkinson’s disease (PD). Data to date from these different programs have been or are being published as follows: in the AD studies, data revealed that oral dosing with dapansutrile inhibits pathophysiological inflammatory processes, recovers significant cognitive losses and prevents neuroinflammation in the brains of transgenic mice induced with AD (see publication in PNAS). In models of MS, dapansutrile exerted anti-inflammatory and protective effects on functional and histological outcomes in experimental autoimmune encephalomyelitis mice, when given prophylactically (see publication in Frontier in Immunology). In MPTP models of PD, dapansutrile showed reduced α-synuclein aggregation, preserved dopaminergic neuron survival and reduced IL‑18 levels. In spinal cord injury (SCI) models, dapansutrile protected against neurological deficits and histological evidence of damage (see publication in Experimental Neurology).
