Clinical Trial Summary

This project will study intranasal (IN) insulin in Frontotemporal dementia (FTD) in 12 patients. Study Investigators aim to evaluate the feasibility of the EXAMINER cognitive battery as a cognitive outcome measure in FTD, the ability of the HealthPartners Center for Memory and Aging's ability to sufficiently recruit subjects with FTD, and the safety of IN regular insulin administered 20 IU twice per day in two specific variants of FTD (behavioral variant frontotemporal dementia (bv-FTD), semantic dementia (SD)) over a 4 week period.

Description:

Frontotemporal dementia (FTD) with its multiple pathological manifestations, is a disease that results in progressive deterioration of social comportment, executive function, and language. Despite the debilitating nature of FTD and the relatively high prevalence in the younger patient population, available pharmacological interventions are limited to symptomatic treatments. There are no therapeutic agents that have been developed that specifically treat the progressive cognitive symptoms of FTD. This project will study IN insulin in FTD in 12 patients.

Eligibility

Inclusion Criteria:

1. Male or female subject meeting international consensus criteria for probable behavioral variant frontotemporal dementia or criteria for semantic dementia (Gorno-Tempini et al., 2011; Rascovsky et al., 2011)

2. Subject has a Mini-Mental State Exam (MMSE) score =18.

3. Subject is > 40 and <90 years of age.

5. The subject must be proficient in speaking, reading and understanding English in order to comply with procedural testing of cognitive function, memory and physiology.

6. Subject has a dedicated family member/caregiver, who will be able to attend all visits and report on subject's status.

7. Subject and family member/caregiver have both provided fully informed written consent prior to participation. In the event that subject is legally unable to provide informed written consent due to deterioration in cognitive abilities, fully informed written consent must be provided by a legally authorized representative.

8. Subject must have undergone a brain computed tomography (CT) scan or magnetic resonance imaging (MRI) scan as part of receiving frontotemporal dementia (FTD) diagnosis

Exclusion Criteria:

1. Subject has medical history and/or clinically determined evidence of other central nervous system (CNS) disorders including, but not limited to brain tumor, active subdural hematoma, seizure disorder, multiple sclerosis, Alzheimer's disease, vascular dementia, corticobasal syndrome, progressive supranuclear palsy, Parkinson's disease, multiple system atrophy, Lewy body dementia, normal pressure hydrocephalus, Huntington's disease, or Jakob-Creutzfeldt disease presenting as dementia.

2. Subject has medical history and/or clinically determined disorders: current B12 deficiency, chronic sinusitis, untreated thyroid disease, or significant head trauma.

3. Subject has history of any of the following: moderate to severe pulmonary disease, poorly controlled congestive heart failure, significant cardiovascular and/or cerebrovascular events within previous 6 months, condition known to affect absorption, distribution, metabolism, or excretion of drugs such as any hepatic, renal or gastrointestinal disease or any other clinically relevant abnormality that inclusion would pose a safety risk to the subject as determined by investigator.

4. Subject has had previous nasal and/or oto-pharyngeal surgery and severe deviated septum and/or other anomalies.

5. Subject has a history of any psychiatric illness that would pose a safety risk to the subject as determined by investigator.

6. Subject is currently taking any medications (anticholinergics, antihistamines, benzodiazepines, barbiturates, or insulin) that are clinically contraindicated as determined by investigator.

7. Subject has undergone a recent change (<1 month) in their selective serotonin reuptake inhibitors (SSRI) or anti-depressant medication.

8. Subject has current or recent drug or alcohol abuse or dependence as defined by the Diagnostic and Statistical Manual of Mental Disorders 5, Text Revision (DSM-IV TR).

9. Screening laboratory results that are medically relevant, in which inclusion would pose a safety risk to the subject as determined by investigator.

10. The subject has participated in a clinical trial investigation within 1 month of this study.

11. The subject has an insulin allergy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Other	Pre to Post Working Memory Measured by EXAMINER - Dot Counting	Dot counting measures verbal working memory. Participants are asked to count colored shapes on a tables and remember the final total over 6 trials. Scores are totaled as the number of correct answers or the number of answers recalled. Range: 0-27. A higher score indicates better performance.	4 weeks
Other	Pre to Post Verbal Fluency Measured by EXAMINER - Animal Fluency	Participants are asked to name as many animals as he/she can in 60 seconds. Scores are totaled as the number of animals verbalized. A higher score indicates better performance.	4 weeks
Other	Pre to Post Inhibition by EXAMINER - Flanker	Participants are asked to choose the direction of one the center arrow in a group 5 arrows. Range: 0- 10. This is a global score that combines accuracy and reaction time. A higher score indicates better performance.	4 weeks
Other	Pre to Post Inhibition by EXAMINER - Set Shifting	Participants are asked to match stimulus on different parts of a tablet screen. Range: 0- 10. This is a global score that combines accuracy and reaction time. A higher score indicates better performance.	4 weeks
Other	Pre to Post Appetite Changes by the Appetite and Eating Habit Questionnaire (APEHQ) - Swallowing Subscore	A survey about changes in eating behaviors. The sum of frequency times severity of swallowing related questions is the score for this portion. Caregivers of participant are asked to fill this survey out. Range: 0-96. Higher scores indicate higher difficulty swallowing that produces conflict or embarrassment.	4 weeks
Other	Pre to Post Appetite Changes by the Appetite and Eating Habit Questionnaire (APEHQ) - Appetite Subscore	A survey about changes in eating behaviors. The sum of frequency times severity of appetite related questions is the score for this portion. Caregivers of participant are asked to fill this survey out Range: 0-96.
