In this Phase I trial, researchers will test the safety and efficacy of the experimental drug AZD3293 in healthy volunteers and people with mild to moderate Alzheimer's disease.

All Participants

  • Women must be of non-childbearing potential.
  • Body mass index of 19 to 30 kg/m2, inclusive
  • Weight of 50-100 kg, inclusive

Participants with Alzheimer's Disease

  • Clinical diagnosis of probable Alzheimer's disease according to the NINCDS-ADRDA criteria
  • Evidence of Alzheimer's symptoms at least 6 months before start of trial

All Participants

  • History of use of antipsychotic drugs or chronic use of antidepressant or anxiolytic drugs
  • Frequent use of tobacco or other nicotine products (more than 2 days per week during the last 12 weeks)
  • History of neurological disease other than Alzheimer's, including seizures, recent memory impairment, or clinically significant head injury

Participants with Alzheimer's Disease

  • Significant disease affecting the central nervous system other than Alzheimer's disease, including but not limited to other dementias and major psychiatric disease

 Healthy Controls

  • History or presence of psychiatric disease or condition
  • Gastrointestinal, renal, hepatic, cardiovascular, or retinal diseases or disorders

The safety and efficacy of the experimental drug AZD3293 will be tested and compared in two groups of participants, healthy older adults and older adults with mild to moderate Alzheimer's dementia. Different doses of the oral solution will be given. AZD3293 inhibits the enzyme beta-secretase, which contributes to damage to nerve cells in the brains of people with Alzheimer's. It is being investigated as a possible treatment for the disease.
