LP143 Centrally Acting Full Agonist to the Cannabinoid Type 2 (CB2) Receptor Targeting a Broad Range of Neurodegenerative Diseases
LP143 Summary Potential to Redefine Treatment of Neurodegenerative Diseases LP143: Designed to be a centrally acting full CB2 agonist with the following preclinical observations and design features: High brain-to-plasma ratio Demonstrated to be 1000x more selective for CB2 than CB1 in preclinical models; Selectivity for CB2 potentially reduces risk of psychoactive effects and abuse liability High oral bioavailability Designed to internalize the CB2 receptor / no tachyphylaxis CB2 Evidence in CNS Diseases: Microglial cells are critical for neuron homeostasis - In neurodegenerative disease, microglial cells activate triggering a shift from neuroprotective to proinflammatory phenotypes Inflammatory processes in non-neuronal cells have shown to play an important role in driving motor neuron degeneration CB2 receptors primarily located on microglia, with some expression in astrocytes and neurons Preclinical data indicate that CB2 agonism has the potential to restore the neuroprotective phenotype of microglial cells Preclinical support exists for indications including: ALS – Longboard initial focus Alzheimer’s Parkinson’s Huntington’s
ALS is an Orphan Motor Neuron Disease with Poor Prognosis Average time from diagnosis to paralysis and death from respiratory failure is 2-5 years Progressive neurodegenerative disease that affects upper and lower motor neurons (MNs) Characterized by rapid progression of muscle wasting and weakness. Patients typically present with weakness, spasticity, cachexia, and/or slurred speech Incidence 2 per 100,000 (most diagnosed 55-65 years) US National ALS Registry identified 16.6K people living with ALS, and 29K estimated in EU as of 2015 Approved treatments provide limited benefit - No significant benefit in survival curves 2015 ALS Prevalence (US) Mehta P, Kaye W, Raymond J, et al.

Neuroinflammation Mediated by Microglial Activation Plays an Important Role in ALS Progression Inflammatory processes in non-neuronal cells have been shown to play an important role in driving motor neuron degeneration Studies of ALS animal models show that microglial cells initially have a neuroprotective phenotype that promote tissue repair and enhance motor neuron survival in the early, slowly progressive stages of the disease At the later, more rapidly progressing disease stage, microglial cells shift to a neuroinflammatory phenotype that is toxic to motor neurons Cross-talk between motor neurons, astrocytes, and immune cells (including microglia, T lymphocytes, and macrophages) in a healthy individual (a) and an ALS patient (b) Rizzo, F., Riboldi, G., Salani, S. et al.

Preclinical Data Indicate that CB2 Agonism Has the Potential to Restore the Neuroprotective Phenotype of Microglial Cells CB2 activation has shown beneficial effects in animal models of ALS: Reduced microglial mediated neuroinflammation, excitotoxicity and oxidative cell damage Inhibited release of pro-inflammatory cytokines Inhibited glutamate release Neuroinflammation has also been suppressed in Alzheimer’s animal models where it is associated with improvements in neuronal plasticity and memory The spinal cord of ALS patients has been shown to present motor neuron damage triggered by immune system’s cells (microglia/macrophages) that express increased levels of the CB2 receptor. So all these data show how editing CB2-mediated processes could change ALS progression and how much the endocannabinoid system is potentially involved in reducing neuroinflammation, excitotoxicity and oxidative cell damage.” Study Reviewed Evidence Supporting Use of Cannabinoids to Treat ALS Joana Fernandes, PhD Feb. 2017 https://alsnew stoday.com/2017/02/28/can-cannabinoids-be-a-potential-therapeutic-tool-in-amyotrophic-lateral-sclerosis/Giacoppo and Mazzon 2016, https://doi.org/10.4103/1673-5374.197125 “

Neuron S1P1, S1P2, S1P3 and S1P5 Reduced dendritic spine loss Restored neuronal function Protection from excitotoxic death Microglia S1P1, S1P2, S1P3 and S1P5 Reduced microglial activation Enhanced microgliosis Blood-brain Barrier Reduced leakiness Astrocyte S1P1, S1P2, S1P3 and S1P5 Inhibition of proinflammatory cytokine production Stimulation of cell migration Inhibition of astrogliosis Synapse Prevention and reversal of synaptic defects Oligodendrocyte S1P1, S1P3 and S1P5 Promotion of OPC survival Effects on migration, differentiation and process dynamics Enhanced remyelination LP659 Potential to Redefine Treatment of Multiple Grievous, Underserved Neurodegenerative Diseases LP659 Designed to be a centrally acting S1P receptor modulator, addressing a wide range of neurodegenerative diseases High oral bioavailability with direct impact on CNS glial cell S1P receptors Rapid onset and offset of action S1P1 selectivity with no impact on S1P2 or 3 in preclinical models S1PRM Potential Indications and Rationale S1P1, 5 are expressed in the CNS across the microglial, neuron, astrocyte and oligodendrocyte cells S1P receptor modulation may play a role in various neurodegenerative diseases including MS, Parkinson’s, Rett syndrome, Epilepsy, Huntington’s, ALS, etc. S1P receptor modulators have generated billions of dollars of revenues in MS Fingolimod as a Treatment in Neurologic Disorders Beyond Multiple Sclerosis
LP659 Favorable Efficacy and Safety Results Observed in Preclinical MOG-EAE Model MOG-EAE is a widely accepted model of demyelinating disease (ex. MS) Pretreatment of LP659 reduced incidence and disease severity of MOG-EAE in murine model LP659 rapidly reduced circulating lymphocytes, which returned to baseline after clearance of LP659 No notable impact observed on heart rate, mean arterial pressure or body temperature (30 mg/kg) Mean disease score: MOG-EAE Model (Prophylactic, n=12 mice/grp, PO, QD from day 3) Days Untreated 0.5% methylcellulose 0.1mpk LP659 0.3mpk LP659 1mpk LP659 Lymphocyte Reduction (PO, single dose) (Lymphocytes (cells 103/μl)) Dose-dependent decrease in disease progression based upon clinical scoring (0-5) after disease induction Nominal Time (hr) Vehicle 0 mg/kg LP659 0.3 mg/kg LP659 1.0 mg/kg AR252124 1.0 mg/kg All PK/PD studies in male Sprague-Dawley rats. Data on file.MOG-EAE, myelin oligodendrocyte glycoprotein-induced experimental autoimmune encephalomyelitis; MS, multiple sclerosis
LP659 Summary Designed to provide centrally acting S1P receptor modulation, with no impact on S1P2 or 3 High brain to plasma ratio suggests LP659 has the potential to address a wide range of neurodegenerative diseases Oral bioavailability with rapid onset and offset of action LP659: Designed to be a centrally acting S1P receptor modulator with potential to transform the treatment of numerous neurodegenerative diseases Next steps: Ongoing preclinical & IND-enabling work, IND submission expected 2H 2022
