NCT01701089

Brief Summary

This open-label, multiple dose, parallel group study will assess the monoamine oxidase in the brain by in vivo positron emission tomography (PET) and safety of RO4602522 in patients with Alzheimer disease and in healthy volunteers. Patients and volunteers will receive multiple doses of RO4602522 and up to three injections of C11-L-deprenyl-D2 used in the PET.

  • Able to participate in all scheduled evaluations
  • The patient has an appropriate caregiver or community dwelling with caregiver capable of accompanying subject on all visits to the center as judged by the investigator.
  • In the opinion of the investigator the patient and caregiver will be compliant and have a high probability of completing the study.
  • Signed and dated written informed consent obtained from the patient, co-signed by the patient's closest relatives and legally authorized representative, as required by national law for patients that are incapable of giving informed consent.
  • General:
  • Any active disease of the gastrointestinal (GI) system, liver, or kidneys that could result in altered absorption, excess accumulation, or impaired metabolism or excretion of drugs, including a history of major upper or middle GI tract surgery or current significant chronic disease of the GI tract
  • Clinically relevant abnormal history, physical findings, ECG, or laboratory values at the screening assessment
  • History of cancer in the past five years, except for fully treated local basal carcinoma, or fully treated carcinoma in situ of cervix
  • Any major illness occurring within 1 month prior to the screening examination or febrile illness within 5 days prior to first dose
  • History of psychotropic medicine abuse
  • At risk of suicide in the opinion of the investigator or having a Yes to question number 4 or 5 of the Suicidal Ideation section of the C-SSRS
  • Administration of ionizing radiation or radioisotope for research, diagnostics test or therapy within 12 months prior to the present study which would exceed the local yearly radiation dose exposures for participation in research studies (except for dental x-rays, minimal plain films such as chest and ankle X-rays) or subjects who regularly work with ionizing radiation or radioactive material.
  • Participation in a clinical study with an investigational drug within 3 months before screening
  • Positive test for hepatitis B, hepatitis C, or HIV at screening
  • +10 more criteria
