This multi-center, randomized, open-label, single-dose, parallel group study wil l assess the relative bioavailability, tolerability and dose-exposure relationsh ip of a high concentration liquid formulation (HCLF) versus a lyophilized formul ation (LyoF) of gantenerumab (RO4909832) in healthy volunteers. Subjects will be randomized to receive single subcutaneous doses of either HCLF or LyoF. Anticip ated time for treatment period and follow-up will be 13 weeks.

Ages Eligible for Study:   40 Years to 70 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Healthy male and female subjects, 40 to 70 years of age. Healthy status is defined by absence of evidence of any active or chronic disease following a detailed medical and surgical history and a complete physical examination
  • Body mass index 18.0 to 30.0 kg/m2 inclusive
  • Female subjects who are either surgically sterilized or post-menopausal
  • Agree not to donate blood or blood products for transfusion for the duration of the study and for one year after their dosing

Exclusion Criteria:

  • Suspicion of alcohol or drugs of abuse addiction
  • Positive for hepatitis B, hepatitis C or HIV 1 or 2 infection
  • Participation in an investigational drug or device study within three months before dosing
  • Concomitant disease or condition or treatment which could interfere with the conduct of the study or that would, in the opinion of the investigator, pose an unacceptable risk to the subject in this study
  • Any clinically relevant history of hypersensitivity or allergic reactions, either spontaneous or following drug administration or exposure to food or environmental agents
  • Any familial history of early onset Alzheimer's disease
  • Claustrophobia, presence of pacemakers, aneurism clips, artificial heart valves, ear implants, or foreign metal objects in the eyes, skin or body which would contraindicate an MRI scan
