The present study is designed as an open label study of patients with mild cognitive impairment or dementia to evaluate longer term tolerability and potential efficacy of tyrosine kinase inhibitors. Baseline and outcome measures in this study utilize validated tests that are appropriate for repeated measures which are not affected by practice effects. Advantages of this study include the fact that the neuropsychological testing instruments and advanced MRI imaging protocols that have been in routine clinical deployment provide for a high degree of availability and reliability for diagnosis and for monitoring change of status. Quality assurance is tightly controlled. The study population is sufficiently broad and the conditions of interest are sufficiently prevalent so that recruitment of the projected numbers of subjects is not a limiting factor. For a Phase I trial there is a proposed 150 patient sample to determine the frequency of common side effects in the population that is being studied. Subjects will be administered the initial dose of bosutinib, with dosage progressively increased over the course of the study. The initial dose of bosutinib is 100 mg tablet, once per day. The dose will be increased as tolerated up to 300 mg per day. All subjects will be started at 100 mg/day and the dose will be increased by 100 mg each month if the lower dose is tolerated without significant side effects. That is to say, the subject will take 100 mg/day every day for the first month, 200 mg/day every day for the second month, and 300 mg/day every day for the third month and for the remainder of the study, provided that adverse reactions do not prohibit continuation at this dosage. The investigators will be using the Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0 to monitor, evaluate, and report adverse reactions on an ongoing basis. Stopping and dose reduction rules for reported adverse reactions have been taken from the package insert of bosutinib.
