Bisnorcymserine in Healthy Adult Volunteers

Start: November 2012
End: January 8, 2019
Enrollment: 200

What Is This Study About?

The experimental drug bisnorcymserine (BNC) may help improve brain function and symptoms in people with Alzheimer's by blocking a chemical that affects how nerve cells in the brain communicate with each other. Researchers want to see how BNC works and whether it is safe in healthy older volunteers.

  • If female, pregnant or lactating
  • Positive urine test for drugs of abuse at screening
  • Out-of range lab test results deemed clinically significant by the Principal Investigator; any clinically significant abnormality on screening EKG (such as heart block, conduction disorders, ventricular and/or atrial arrhythmias)
  • Systolic blood pressure outside 90-140 mmHg or diastolic blood pressure outside 50-90 mmHg, taken while lying down, on two consecutive measurements taken up to 10 minutes apart

  • Prohibited medications: insulin; anti-parkinsonian medications (such as sinemet, amantadine, bromocriptine, pergolide, selegiline); typical or atypical neuroleptics; narcotic analgesics, long-acting benzodiazepines, or long-acting barbiturates within 4 weeks prior to screening; short-acting anxiolytics or sedative hypnotics taken more than twice a week within 4 weeks prior to screening; medications with known significant cholinergic or anticholinergic side effects (such as pyridostigmine, tricyclic antidepressants, meclizine, oxybutynin) within 4 weeks prior to screening; anticonvulsants (such as phenytoin, phenobarbital, carbamazepine) within 2 months prior to screening; medications for Alzheimer's disease (such as donepezil or memantine); beta-blockers; systemic corticosteroids; neuromuscular-blocking agents; succinylcholine; any other drug that would, in the opinion of the Principal Investigator, pose a risk to the subject or produce overlapping side effects with the study medication
  • Donation or loss of 400 mL or more of blood within 56 days prior to and subsequent to screening
  • Participation in another research study involving an investigational drug within 30 days or 5 half-lives, whichever is longer
  • Known allergy or hypersensitivity to the investigational study drug or placebo components
