Clinical Trial of Solanezumab for Older Individuals Who May be at Risk for Memory Loss


  • Study type

  • Study phase

  • Study IDs

  • Describes the nature of a clinical study. Types include:

    • Observational study — observes people and measures outcomes without affecting results.
    • Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
    • Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
  • During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study

The purpose of this study is to test whether an investigational drug called solanezumab can slow the progression of memory problems associated with brain amyloid (protein that forms plaques in the brains of people with Alzheimer Disease [AD]).

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. If you need assistance understanding the eligibility criteria, please contact the study team.

See eligibility criteria

Inclusion Criteria:

  • Has a Mini-Mental State Examination (MMSE) score at screening of 25 to 30
  • Has a global Clinical Dementia Rating (CDR) scale score at screening of 0
  • Has a Logical Memory II score at screening of 6 to 18
  • Has a florbetapir positron emission tomography (PET) scan that shows evidence of brain amyloid pathology at screening
  • Has a study partner that is willing to participate as a source of information and has at least weekly contact with the participant (contact can be in-person, via telephone or electronic communication)

Exclusion Criteria:

  • Is receiving a prescription acetylcholinesterase inhibitor (AChEI) and/or memantine at screening or baseline
  • Lacks good venous access, such that intravenous drug delivery or multiple blood draws would be precluded
  • Has current serious or unstable illness including cardiovascular, hepatic, renal, gastroenterologic, respiratory, endocrinologic, neurologic, psychiatric, immunologic, or hematologic disease or other conditions that, in the investigator's opinion, could interfere with the analyses of safety and efficacy in this study
  • Has had a history within the last 5 years of a serious infectious disease affecting the brain (including neurosyphilis, meningitis, or encephalitis) or head trauma resulting in protracted loss of consciousness
  • Has had a history within the last 5 years of a primary or recurrent malignant disease with the exception of resected cutaneous squamous cell carcinoma in situ, basal cell carcinoma, cervical carcinoma in situ, or in situ prostate cancer with normal prostate-specific antigen posttreatment
  • Has a known history of human immunodeficiency virus (HIV), clinically significant multiple or severe drug allergies, or severe post-treatment hypersensitivity reactions (including, but not limited to, erythema multiforme major, linear immunoglobulin A dermatosis, toxic epidermal necrolysis, or exfoliative dermatitis)
  • Is clinically judged by the investigator to be at serious risk for suicide
  • Has a history within the past 2 years of major depression or bipolar disorder as defined by the most current version of the Diagnostic and Statistical Manual of Mental Disorders (DSM)
  • Has a history within the past 5 years of chronic alcohol or drug abuse/dependence as defined by the most current version of the DSM
