MCLENA-1: A Clinical Trial for the Assessment of Lenalidomide in Amnestic MCI Patients

Description

Accumulating evidence indicates that inflammation is prominent both in the blood and central nervous system (CNS) of Alzheimer's disease (AD) patients. These data suggest that systemic inflammation plays a crucial role in the cause and effects of AD neuropathology. Capitalizing on the experience from a previous clinical trial with thalidomide, here, the investigators hypothesize that modulating both systemic and CNS inflammation via the pleiotropic immunomodulator lenalidomide is a putative therapeutic intervention for AD if administered at a proper time window during the course of the disease.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

For general information about clinical research, read Learn About Studies.

Eligibility Criteria

  • * In order to be eligible for this study, subjects must meet the following
  • * Subjects will be excluded if they have any of the condition listed below:
  • 1. Current evidence or history within the last 3 years of a neurological or psychiatric illness that could contribute to dementia, including (but not limited to) epilepsy, focal brain lesion, Parkinson's disease, seizure disorder, head injury with loss of consciousness
  • 2. DSM IV criteria for any major psychiatric disorder including psychosis, major depression and bipolar disorder.
  • 3. Known history or self-reported alcohol or substance abuse.
  • 4. Isolated living circumstances which would prohibit a study partner from providing sufficient and credible information about the participant.
  • 5. Poorly controlled hypertension.
  • 6. History of myocardial infarction or signs or symptoms of unstable coronary artery disease within the last year (including revascularization procedure/angioplasty).
  • 7. Severe pulmonary disease (including chronic obstructive pulmonary disease) requiring more than 2 hospitalizations within the past year.
  • 8. Untreated sleep apnea.
  • 9. Any thyroid disease (unless euthyroid or on treatment for at least 6 months prior to screening).
  • 10. Active neoplastic disease (except for skin tumors other than melanoma). Patients with a history of prior malignancy are eligible provided they were treated with curative intent and (i) do not require any longer any active therapy; (ii) being considered in complete remission; and (iii) after the Medical Monitor's assessment/approval of each case.
  • 11. History of multiple myeloma.
  • 12. Absolute neutropenia of \<750mm3, or history of neutropenia.
  • 13. History of or current thromboembolism (including deep venous thrombosis).
  • 14. Any clinically significant hepatic or renal disease (including presence of Hepatitis B or C antigen/antibody or an elevated transaminase levels of greater than two times the upper limit of normal (ULN) or creatinine greater than 1.5 x ULN).
  • 15. Clinically significant hematologic or coagulation disorder including any unexplained anemia or a platelet count less than 100,000/μL at screening.
  • 16. Use of any investigational drug within 30 days or within five half-lives of the investigational agent, whichever is longer.
  • 17. Use any investigational medical device within two weeks before screening or after end of the present study.
  • 18. Females who are at risk of pregnancy or are of child bearing age.
  • 19. Any other disease or condition that, in the opinion of the investigator, makes the patient unsuitable to participate in this clinical trial.
  • 20. Unwilling or unable to undergo MRI and PET imaging.
  • 21. Cardiac pacemaker or defibrillator or other implanted device.
  • 22. In the opinion of the Investigator, participation would not be in the best interest of the subject.
