- Change in α-synuclein and Tau concentrations in the CSF and serum of patients [ Time Frame: 6 months ]Working Hypothesis: PD patients have been shown to have elevated levels of α-synuclein in their CSF. Nilotinib has been shown to reduce α-synuclein and Tau in the gastrointestinal tract and central nervous system in animal models, and similarly, we propose will show changes in CSF and serum α-synuclein concentrations in nilotinib treated PD patients.
- Determine nilotinib's efficacy by improvement in motor and non-motor symptoms [ Time Frame: 6 months ]
Working Hypothesis: By following strict safety guidelines, monitoring patients through physical examinations, self-examinations, laboratory and neurological examinations, nilotinib will be a safe drug to use in patients with PD and PD related patients.
Determine if any clinical benefit is observed in this small, short, limited clinical trial.
Working Hypothesis: In cell culture and animal models of PD, dopaminergic neurons have shown increased cell death with accumulating α-synuclein. Therefore, PD patients treated with nilotinib, which lowers α-synuclein and Tau in vivo and in vitro studies, will have improvement or stabilization of their motor UPDRS and cognition.
- Safety and tolerability, as measured by number of Participants with Adverse Events [ Time Frame: 6 months ]
Working Hypothesis: By following strict safety guidelines, monitoring patients through physical examinations, self-examinations, laboratory and neurological examinations, nilotinib will be a safe drug to use in patients with PD and PD related patients.

Ages Eligible for Study: | 40 Years to 90 Years (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | Yes |
Inclusion Criteria:
1. Patients aged 40 to 90 with Idiopathic Parkinson's Disease (Significant Sinemet response) on a stable medication drug regimen L-dopa and/or Dopamine agonist (at least 1 month before enrollment with no new medication change) and with moderate to severe cognitive impairment (MOCA ≤24).
Inclusions criteria:

- Patients between the age of 40-90 y
- Diagnosis of PD according to the UK Brain Bank Diagnostic Criteria
- Early PD subjects with MMSE between 23-30.
- Hoehn and Yahr stage <2
- Stable treatment (>4 weeks) with MAO-B inhibitor (Selegeline up to 10mg/d or rasagiline up to 1 mg/d) allowable
- Patients not needing dopamine agonist or levodopa therapy presently or at least for the next 6 months
- Idiopathic PD with NO genetic mutations (autosomal recessive or dominant)
- Detectable levels of CSF for blood and CSF Alpha-Synuclein
Exclusion Criteria:
- Patients with a known genetic form of PD that does not involve alpha-synuclein.
- Unwillingness to undergo lumbar punctures
- Immeasurable CSF α-synuclein.
- Presence of dementia or severe cognitive impairment that would not permit the patient to give adequate feedback for potential side effects.
- Unwilling to be in an off state for UPDRS assessment.
- Pre-menopausal women
- Patients with autosomal recessive (PARKIN, PINK1 or DJ1) or dominant mutations (LRRK2)
- Patients with hypokalemia, hypomagnesaemia, or long QT syndrome.
- Concomitant drugs known to prolong the QT interval
- Strong CYP3A4 inhibitors
- Any drugs or foods that may interact with Nilotinib as stated in the Package Insert (PI).
- Medical history of liver and pancreatic diseases.
- Clinical signs indicating syndromes other than idiopathic PD, including supranucelar gaze palsy, signs of frontal dementia, history of stroke, head injury or encephalitis, cerebellar sings, early severe autonomic involvement, Babinski's signs.
- History of any cardiovascular disease, including hypertension, myocardial infraction or cardiac failure, angina, arrhythmia.
