Dementia With Lewy Bodies
Conditions
Brief summary
Dementia with Lewy Bodies (DLB) is an alphasynucleinopathy and the second most common form of dementia in the elderly. DLB shares striking neuropathological and clinical similarities with both Parkinson's disease (PD) and Alzheimer's disease (AD). Nilotinib (Tasigna®, AMN107, Novartis, Switzerland) is approved by the FDA and is well tolerated for CML treatment at oral doses of 600-800mg daily. The Investigators propose to perform a phase II randomized, double blinded, placebo controlled study to evaluate the impact of Nilotinib in patients with DLB.
Detailed description
A phase II randomized, double blinded, placebo controlled study will be performed to evaluate the impact of Nilotinib (Tasigna®, AMN107, Novartis, Switzerland) on safety, tolerability, pharmacokinetics, pharmacodynamics and clinical outcomes in patients with Dementia with Lewy Bodies. Sixty ( 60) participants will be recruited and randomly assigned 1:1 to placebo (arm 1) or 200 mg Nilotinib (arm 2).This study will be conducted in DLB patients with 2.5≥Hoehn & Yahr≤3 and UPDRS I-III ≤50 and 15≥UPDRS III (motor) ≥40 (Unified Parkinson's Disease Rating Score)and MoCA≥18(Montreal Cognitive Assessment). Eligible participants must be stable on MAO-B inhibitors (Rasageline or Selegeline) for 4 weeks and must not be on ≥800mg Levodopa daily. Participants must be stable on acetylcholinesterase inhibitors and other medications for at least 6 weeks. Participants will be treated for 6 months and monitored every month ( 4 weeks) in a total of 9 visits that include screening , baseline, 1, 2, 3, 4, 5, 6 months follow up and 7 month washout. Blood and cerebrospinal fluid (CSF) will be collected at baseline and at 6 months to determine Nilotinib effects on CSF biomarkers.
Interventions
DRUGPlacebo oral capsule
Thirty (30) patients in arm 1 will receive the matching placebo ("sugar pill") one (1) capsule orally (without food) once daily for 6 months (180 days).
DRUGNilotinib Oral Capsule
Thirty (30) patients in arm 2 will receive the 200 mg of Nilotinib one (1) capsule orally (without food) once daily for 6 months (180 days).

Masking description
Participants will be randomized by a Biostatistician by an internet based randomization module into two groups. The researchers include : Primary investigator , Sub-Investigators ,Clinical Coordinators, Nurse Practitioners , and Clinical Reseach unit staff.
Intervention model description
Investigators will evaluate the effects of 200 mg of Nilotinib versus matching Placebo taken daily by mouth for 6 Months, followed by 1 Month wash-out period in individuals with DLB. Sixty (60) participants will be recruited and randomly assigned 1:1 to placebo (arm 1) or 200 mg Nilotinib (arm 2). Participants will be treated for 6 months and monitored every month (4 weeks) in a total of 9 visits that include screening, baseline, 1, 2, 3, 4, 5, 6 months follow up and 7-month washout.

Inclusion criteria
1. Written informed consent 2. Capable of providing informed consent and complying with study procedures. Subjects who are unable to provide consent may use a Legally Authorized Representative (LAR). 3. Clinical diagnosis of DLB according to McKeith et al (7) with both dementia MoCA≥18 and Parkinsonian defined as bradykinesia in combination with rest tremor, rigidity or both UPDRS I-III is less than 50 and/or UPDRS-III between 15 -40 on-state. Dementia and Parkinsonism must be present with at least one other symptom such as fluctuation, visual hallucinations or REM sleep behavioral disorder (RBD) 4. 2.5 ≥Hoehn and Yahr stage ≤3 5. MDS-UPDRS-III 15-40 on-state (or up to 70 on the off state) 6. Abnormal DaTScan 7. Stable concomitant medical and/or psychiatric illnesses in the judgement of the PI 8. Patients between the age of 25-90 years, medically stable 9. Must NOT be stable on mono-amine oxidase (MAO)-B inhibitors (Selegeline or rasagiline) for at least 4 weeks before enrollment and during Nilotinib treatment. 10. Must be medically stable on less than or equal to 800mg Levodopa daily for at least 4 weeks 11. QTc interval 350-460 ms, inclusive 12. Participants must be willing to undergo LP at baseline and 6 months after treatment
Exclusion criteria
1. Patients with hypokalemia, hypomagnesaemia, or long QT syndrome- QTc≥461 ms 2. Concomitant drugs known to prolong the QTc interval and history of any cardiovascular disease, including myocardial infraction or cardiac failure, angina, arrhythmia 3. History or presence of cardiac conditions including: 1. Cardiovascular or cerebrovascular event (e.g. myocardial infarction, unstable angina, or stroke) 2. Congestive heart failure 3. First, second- or third-degree atrioventricular block, sick sinus syndrome, or other serious cardiac rhythm disturbances 4. Any history of Torsade de Pointes 4. Treatment with any of the following drugs at the time of screening or the preceding 30 days, and/or planned use over the course of the trial: 1. Treatment with Class IA or III antiarrhythmic drugs (e.g. quinidine) 2. Treatment with QT prolonging drugs (www.crediblemeds.org)- excluding Selective Serotonin Reuptake Inhibitors (SSRIs) (e.g. Citalopram, Paxil, Zoloft, Cymbalta, Sertraline, etc...) 3. Strong CYP3A4 inhibitors (including grapefruit juice). The concomitant use of strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, clarithromycin, atazanavir, indinavir, nefazodone, nelfinavir, ritonavir, saquinavir, telithromycin, voriconazole) must be avoided. Grapefruit products may also increase serum concentrations of Nilotinib. Should treatment with any of these agents be required, therapy with Nilotinib should be interrupted. 4. Anticoagulants, including Coumadin (warfarin), heparin, enoxaparin, daltiparin, xarelto, etc. 5. St. John's Wort and the concomitant use of strong other CYP3A4 inducers (e.g., dexamethasone, phenytoin, carbamazepine, rifampin, rifabutin, rifapentine, phenobarbital) must be avoided since these agents may reduce the concentration of Nilotinib. 5.

| DLB Related CSF Biomarkers | 6 Months | Pharmacodynamics: Determine the effects of Nilotinib on primary biomarkers |
| The Investigators Will Quantify Amyloid Burden Via Florbetaben PET Scan | Baseline, 6 Months, and change between baseline and 6 months | Quantification of Standardized Uptake Value Ratio (SUVR) of brain amyloid burden via Florbetaben (Neuraceq, is a diagnostic radiotracera) PET at baseline and 6 months (end of treatment (EOT)). Standardized Uptake Value Ratio (SUVR) is a unitless ratio that measures tracer uptake in a target brain region compared to a reference region. A lower SUVR is generally better in amyloid PET scans, as it indicates a lower density of amyloid plaques in the brain while a higher SUVR indicates a higher burden of amyloid plaque accumulation in the brain. |
