3-month Study of MSDC-0160 Effects on Brain Glucose Utilization, Cognition & Safety in Subjects With Alzheimer's Disease

Completed · Phase 2 · Has a placebo group

Conditions studied: Alzheimer's Disease

In brief

This study will evaluate the effect of 150 mg MSDC-0160 taken daily for 90 days compared to the effect of placebo on changes in brain glucose utilization using FDG-PET and cognition in older persons with mild Alzheimer's disease. Safety and tolerability of MSDC-0160 in this population will also be studied. These results will be used to design larger studies of MSDC-0160 in persons with mild Alzheimer's disease.

Who can join

Age: 55 and older, up to 85. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Male or females 55-85 years of age.
• Females should be either postmenopausal or surgically sterilized. Males with female partners of child-bearing potential must use contraception if engaging in sexual intercourse.
• Diagnosis of probable Alzheimer's disease based on NIA-AA criteria with MMSE scores of 20 or greater.
• Willing and able to take part in up to six study visits over a 5-month period, with the support of a caregiver as needed.
• Willing and able to sign an informed consent document indicating understanding the purpose of and procedures required for the study and willingness to participate in the study, with the support of a caregiver as needed.

You may not qualify if…

• Diagnosis of diabetes, including use of anti-diabetic medications, or fasting plasma glucose >125 mg/dl or Hemoglobin A1c>6.4%.
• Unable to participate in FDG-PET scanning, including:
• Inability to cooperate/claustrophobia (no sedation offered for this protocol).
• Inability to lie still on the scanner bed for 40 minutes.
• Total radiation dose exposure to the subject in any given year exceeds the limits of annual and total dose commitment of 50 mSv (5 REMs). The two FDG-PET scans will result in an approximate exposure of 10 mSv (1 REM).
• Diagnosis of significant neurological/psychiatric disease other than AD, including, but not limited to, any of the following: vascular dementia according to NINDS-AIREN criteria, space occupying cerebral lesion, Huntington's Disease, Parkinson's Disease, normal pressure hydrocephalus, and seizures.
• History of heart failure (including CHF).
• Previous cardiovascular event (myocardial infarct, by-pass surgery, or PTCA) within the past 6 months prior to screening.
• Inability to undergo a clinical (1.5T) MRI of the brain without contrast and lack of a usable (less the 12 months prior to screening) MRI on record. Contraindications to undergoing an MRI of the brain include, but are not limited to, pacemakers; implantable cardioverter defibrillators; cochlear implants; cerebral aneurysm clips; implanted infusion pumps; implanted nerve stimulators; metallic splinters in the eye; and, other magnetic, electronic or mechanical implants or clinical findings that in the judgment of the investigator would pose a potential hazard in combination with MRI.
• ALT and/or AST levels that are twice the upper limit of normal; bilirubin levels that exceed 2 mg/dL; serum creatinine >1.5 mg/dL in men or > 1.4 mg/dL in women.
• Current or history of severe or unstable disorder (medical or psychiatric) requiring treatment that may make the subject unlikely to complete the study.
• Malignancy (other than non-melanoma skin cancer) within the last 5 years.
• Known history of HIV, hepatitis B, or hepatitis C.
• Blood pressure greater than 160/100 mmHg. Subjects with elevated BP will be allowed at the discretion of the principal investigator. Individuals with hypertension must have been stabilized to the current treatment regimen for at least 6 weeks prior to screening and not need adjustments to their treatment regimen during the entire study period.
• Change in other medications to treat Alzheimer's disease within 3 months prior to screening. Change in medication to treat other conditions within 6 weeks prior to screening or during the study period.
• Known or suspected intolerance or hypersensitivity to the study drugs, closely related compounds, or any of their stated ingredients.
• History of alcohol or drug abuse within 6 months of screening.
• Have participated in an investigational study or received an investigational drug within 30 days or 5 half-lives (whichever is longer) prior to study drug administration.
• Single 12-lead ECG demonstrating a QTcB >450 msec or other clinically significant finding at screening. A single repeat ECG may be done at the investigator's discretion.
• Any surgical or medical condition which may significantly alter the absorption of any drug substance including, but not limited to, any of the following: history of major gastrointestinal tract surgery, currently active inflammatory bowel syndrome.
• Evidence of clinically relevant pathology that in the investigator's opinion could interfere with the study results or put the subject's safety at risk.
