Inclusion Criteria: * 1- Diagnosis of dementia due to AD 2- Meet the National Institute of Aging-Alzheimer's Association (NIA-AA) core clinical criteria for dementia due to AD 3- Have a global CDR score of 0.5 to 1.0 and a CDR Memory Box score of 0.5 or greater at Screening and Baseline 4- Have an MMSE score greater than or equals to 20 at Screening and less than or equals to 27 at Screening and Baseline 5- Have a positive amyloid PET (visual reading) or positivity threshold of CSF Aβ\[1-42\] \< 660ng/ml or ptau/Aβ\[1-42\] \>0.09 using INNOTEST Enzyme-Linked ImmunoAssay (ELISA) technique (Fujirebio, Ghent, Belgium). 6- QTc (corrected Q wave to the end of the T wave) interval 350-480 ms, inclusive for both men and women 7- English or Spanish fluency 8- Report a history of subjective memory decline with gradual onset and slow progression over the last 1 year before Screening; must be corroborated by an informant 9- Positive biomarker for brain amyloid pathology as indicated by at least 1 of the following: 1. PET assessment of imaging agent uptake into brain 2. CSF assessment of Aβ\[1-42\] or ptau/Aβ\[1-42\] NOTE: To confirm eligibility, a positive amyloid result is needed in only 1 of the 2 procedures, including PET or CSF measurement. 10- Male or female subjects aged ≥55 and ≤ 85 years, at the time of informed consent (IC) 11- Body mass index (BMI) greater than 17 and less than 35 at Screening 12- If receiving an approved AD treatment, such as acetylcholinesterase inhibitors (AChEIs), or memantine, or both for AD, must be on a stable dose for at least 12 weeks prior to Baseline. Treatment-naïve subjects for AD can be entered into the study. Unless otherwise stated, subjects must have been on stable doses of all other (i.e., non-AD-related) permitted concomitant medications for at least 4 weeks prior to Baseline. 13- Have an identified study partner. The study partner must provide separate written IC. In addition, this person must be willing and able to provide follow-up information on the subject throughout the course of the study. This person must, in the opinion of the investigator, spend sufficient time with the subject on a regular basis such that the study partner can reliably fulfill the study requirements. A permanent study partner need not be living in the same residence with the subject. For such a study partner not residing with the subject, the investigator has to be satisfied that the subject can contact the study partner readily during the times when the study partner is not with the subject. Study partners need to participate in person for visits where clinical assessment of CDR (global and CDR-SB), ADAS-Cog, ADCS-ADL-MCI and NPI. 14- Provide written IC. If a subject lacks capacity to consent in the investigator's opinion, the subject's assent should be obtained, if required in accordance with local laws, regulations and customs, plus the written IC of a legal representative should be obtained. 15- Willing and able to comply with all aspects of the protocol. Biomarker Sub-study NOTE: Subjects may consent to either one or both the PET and CSF assessments, but to confirm eligibility, a positive amyloid result is needed in only 1 of the 2 procedures (Amyloid PET (via visual reading) or CSF assessment). The historical imaging data and CSF assessment results must be made available to the sponsor or medical monitor to confirm amyloid positivity and eligibility. Historical PET and CSF assessments will ONLY be used for determination of eligibility. However, subjects who enroll in the biomarker sub study MUST participate in one or more of the amyloid and tau PET, vMRI and CSF assessments according to the Assessments Schedule in the sponsor protocol. Patients may use any amyloid PET tracer to prove eligibility, but they must use only the sponsor provided tracer at Baseline and End of Treatment- unless the same tracer was used within 12 months from Baseline and the data can be provided to the investigator and the subject has not participated in any subsequent anti-amyloid study or treatment. Exclusion Criteria: 1. Subjects who are on anti-amyloid therapy (i.e. vaccine or antibody) or who were receiving anti-amyloid vaccines (i.e. aducunamab) or anti-tau vaccines less than 3 months before Screening. 2. Women of childbearing potential (WCBP). NOTE: All females will be considered to be of childbearing potential unless they are postmenopausal or have been sterilized surgically (i.e., bilateral tubal ligation, total hysterectomy, or bilateral oophorectomy, all with surgery at least 1 month before dosing). 3. Any neurological condition that may be contributing to cognitive impairment above and beyond that caused by the subject's AD. 4. Any psychiatric diagnosis or symptoms, (e.g., hallucinations, major depression, or delusions) that could interfere with study procedures in the subject. 5. Geriatric Depression Scale (GDS) score greater than or equal to 8 at Screening. 6. Contraindications to MRI scanning, including cardiac pacemaker/defibrillator, ferromagnetic metal implants (e.g., in skull and cardiac devices other than those approved as safe for use in MRI scanners). 7. Evidence of other clinically significant lesions on brain MRI that could indicate a dementia diagnosis other than AD. 8. Other significant pathological findings on brain MRI, including but not limited to: more than 4 micro hemorrhages (defined as 10mm or less at the greatest diameter); a single macro hemorrhage greater than 10mm at greatest diameter; an area of superficial siderosis; evidence of vasogenic edema; evidence of cerebral contusion, encephalomalacia, aneurysms, vascular malformations, or infective lesions; evidence of multiple lacunar infarcts or stroke involving a major vascular territory, severe small vessel, or white matter disease; space occupying lesions; or brain tumors (however, lesions diagnosed as meningiomas or arachnoid cysts and less than 1cm at their greatest diameter need not be exclusionary). 9. Patients with hypokalemia, hypomagnesaemia, or long QT syndrome- QTc≥481 ms 10. Concomitant drugs known to prolong the QTc interval and history of any cardiovascular disease, including myocardial infraction or cardiac failure, angina, arrhythmia 11. Presence of cardiac conditions including: 1. Cardiovascular or cerebrovascular event (e.g. myocardial infarction, unstable angina, or stroke) 2. Congestive heart failure 3. Second- or third-degree atrioventricular block, sick sinus syndrome, or other serious cardiac rhythm disturbances 4. Any history of Torsade de Pointes 12. 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 (Tasigna). Should treatment with any of these agents be required, therapy with Nilotinib BE should be interrupted. 4. Anticoagulants, including Coumadin (warfarin), heparin, enoxaparin, daltiparin, xarelto, etc. 13. 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. 14. Any immunological disease which is not adequately controlled, or which requires treatment with immunoglobulins, systemic monoclonal antibodies (or derivatives of monoclonal antibodies), systemic immunosuppressant's, or plasmapheresis during the study. 15. Subjects with a bleeding disorder that is not under adequate control (including a platelet count \<50,000 or international normalized ratio \[INR\] \>1.5 for subjects who are not on anticoagulant treatment, e.g., warfarin). Subjects who are on anticoagulant therapy should have their anticoagulant status optimized and be on a stable dose for 4 weeks before Screening. 16. Have thyroid stimulating hormone above normal range. Other tests of thyroid function with results outside the normal range should only be exclusionary if they are considered clinically significant by the investigator. This applies to all subjects whether or not they are taking thyroid supplements. 17. Abnormally low serum vitamin B12 levels for the testing laboratory (if subject is taking vitamin B12 injections, level should be at or above the lower limit of normal \[LLN\] for the testing laboratory). 18. Known to be human immunodeficiency virus (HIV) positive. 19. Any other clinically significant abnormalities in physical examination, vital signs, laboratory tests, or ECG at Screening or Baseline which in the opinion of the investigator require further investigation or treatment or which may interfere with study procedures or safety. 20. Subjects with malignant neoplasms within 3 years of Screening (except for basal or squamous cell carcinoma in situ of the skin, or localized prostate cancer in male subjects). Subjects who had malignant neoplasms but who have had at least 3 years of documented uninterrupted remission before Screening need not be excluded. 21. Answer "yes" to C-SSRS suicidal ideation Type 4 or 5, or any suicidal behavior assessment within 6 months before Screening, at Screening, or at the Baseline Visit, or has been hospitalized or treated for suicidal behavior in the past 5 years before Screening. 22. Known or suspected history of drug or alcohol abuse or dependence within 2 years before Screening. 23. Any other medical conditions (e.g., cardiac, respiratory, gastrointestinal, renal disease) which are not stably and adequately controlled, or which in the opinion of the investigator(s) could affect the subject's safety or interfere with the study assessments. 24. Subjects who are taking prohibited medications. 25. Participation in a clinical study involving any anti-amyloid therapies (including any monoclonal antibody therapies and any β-site amyloid precursor protein cleaving enzyme \[BACE\] inhibitor therapies) unless it can be documented that the subject only received placebo. 26. Subjects who were dosed in a clinical study involving any new chemical entities for AD within 3 months prior to Screening unless it can be documented that the subject only received placebo. 27. Participated in any other investigational medication or device study in the 8 weeks or 5 half-lives (whichever is longer) of the medication before randomization unless it can be documented that the subject only received placebo. 28. Planned surgery which requires general anesthesia that would take place during the study. Planned surgery which requires only local anesthesia and which can be undertaken as day case without inpatient stay postoperatively need not result in exclusion if in the opinion of the investigator this operation does not interfere with study procedures and subject safety. 29. Severe visual or hearing impairment that would prevent the subject from performing psychometric tests accurately. 30. Any concomitant medication or medication excluded that could put subject at risk, or interfere with study evaluations 31. Exclusion criteria specific for the biomarker sub-study: * Contraindications to LP: prior lumbosacral spine surgery, severe degenerative joint disease or deformity of the spine, platelets \< 100,000, use of Coumadin/warfarin, or history of a bleeding disorder.
