Neurogenetic Pharmaceuticals (NGP) 555 in Healthy Volunteers (14 Day Multiple Ascending Dose)

Phase 1

Completed

• Conditions: Alzheimer's Disease
• Interventions: Drug: NGP 555

• Registration Number: NCT02537938
• Lead Sponsor: NeuroGenetic Pharmaceuticals Inc

Brief Summary

This study involves the use of an investigational drug called NGP 555. In each group of healthy subjects, 2 people will receive placebo and 6 people will receive NGP 555.

Detailed Description

The purpose of this research study is to determine the safety, tolerability, and pharmacokinetics (PK) of multiple (14 days), oral doses of NGP 555 in healthy volunteers.

NGP 555 has been created for the treatment of Alzheimer's disease (AD). NGP 555 is being developed to prevent Abeta 42 amyloid formation, a protein that is likely a key factor in the development of AD.

Inclusion Criteria

1. Male and female volunteers aged 40-65 yrs and in good health as determined by medical history, physical examination, clinical laboratory studies, electrocardiograms (ECGs), vital signs, and investigator judgement

2. Any concurrent disease or condition that, in the opinion of the Investigator, would make the volunteer unsuitable for participation in the clinical study
3. Volunteer has history of alcohol and/or illicit drug abuse within two years of entry
4. Any psychiatric diagnosis or symptoms (e.g., hallucinations, major depression, anxiety or delusions)
5. History of cerebrovascular events or non-vasovagal related loss of consciousness
6. History of cardiac arrhythmias, ischemic heart disease, cerebrovascular disease.

8. Renal impairment as defined by >1.3 abnormal ranges of serum creatinine
9. Abnormal blood pressure
10. Abnormal cardiovascular parameters
11. Volunteers with abnormally low serum B12, folate or abnormal thyroid function tests
12. Positive Screening test for Hepatitis B surface antigen (HBsAg), Hepatitis C antibody, or human immunodeficiency virus (HIV) antibody
13. Positive urine test for alcohol or drugs
14. Any suicidal behavior in the last 2 years
15. Female volunteers that are breastfeeding or female volunteers with a positive urine pregnancy test
16. Volunteers unwilling to avoid consumption of coffee and caffeine containing beverages
17. Unable to abstain from smoking (or other nicotine use)
18. Donation of blood (> 500 mL) or blood products within 2 months
19. Volunteers who take prohibited medications
20. Use of an investigational drug within 30 days prior to Screening (Visit 1)
21. Unwilling to abstain from vigorous exercise
22. Clinically significant deviation from normal in physical examination, vital signs or clinical laboratory tests
23. Volunteer is unable to understand the protocol requirements, instructions and study-related restrictions, the nature, scope and possible consequences of the clinical study
24. Volunteer is unlikely to comply with the protocol requirements, instructions and study-related restrictions (e.g., uncooperative attitude, inability to return for follow-up visit and improbability of completing the clinical study)
25. Volunteer has medical conditions that are unstable or which, in the clinical opinion of the Investigator, may interfere with study procedures or volunteer safety. Volunteers with the following stable medical conditions, adequately controlled with stable doses of concomitant medications, need not be excluded if in the opinion of the Investigator, their conditions do not compromise volunteer safety or study procedures:
