    TREATING INSIDE AND OUTSIDE OF THE BRAIN Simultaneous Evaluation of Brain and GI Function Identifies a Potential Disease-Modifying Treatment BY 2025, PARKINSON’S § PD is more than just a disease of the brain, DISEASE DRUG SALES ARE EXPECTED TO § GI manifestation in many patients occurs at an early s

  5. Slide 5: Common Features of Misfolded Protein Diseases

    COMMON FEATURES OF MISFOLDED PROTEIN DISEASES 1 Causation in Parkinson’s and Alzheimer’s is closely related What role does the misfolded protein play? 1 Nat. Neurosci. 21: 1332-1340 (2018) 5

  6. Slide 6: The Path to Neurodegeneration

    THE PATH TO NEURODEGENERATION Stressors Trigger the Production of Misfolded α-Synuclein 1 Which Activates c-Abl to Drive Neurodegeneration Immunotherapy acts here 1 6 Werner and Olanow, Mov. Disorders 2022 Jan;37(1):6-15.

  7. Slide 7: Activated c-Abl Is the Gateway in the Disease Path

    ACTIVATED C-ABL IS THE GATEWAY IN THE DISEASE PATH α-Synuclein ‘Plaques’ Do Not Cause Disease Without c-Abl 1 Modification in Humanized Preclinical Models α-Synuclein plaque in the ABSENCE OF c-Abl CAUSES NO NEURODEGENERATION AFTER 6 MONTHS No c-Abl = No neurodegeneration Injection (Inj) of an expre

  12. Slide 12: Effect on Cause of Disease

    EFFECT ON CAUSE OF DISEASE Oral IkT-148009 Treatment Nearly Clears Pathological a-Synuclein in the Brain and Gut Clearance of toxicity in the gut Clearance of toxicity in the brain Green: Pathological a-synuclein Red: Neural ganglia in gut Aggregates Nearly cleared during treatment with IkT- 148009

  13. Slide 13: Summary

    SUMMARY Key points of Parkinson’s Disease Initiation and 1 Progression § Internalization of misfolded or aggregated a-synuclein and the activation of c-Abl in response is a key event in PD initiation/progression § The long-sought goal of clearing a-synuclein aggregates for a therapeutic purpose shou
