Brief Summary:

The purpose of this study is to determine if memantine at up to 20 mg twice a day when used in conjunction with riluzole, can slow down the disease progression of patients with ALS including potentially improving their neuropsychiatric changes, as well as determine if serum biomarkers can be used both as a diagnostic and a prognostic marker in patients with ALS.

Condition or disease Intervention/treatment Phase
Amyotrophic Lateral Sclerosis Frontal Temporal Dementia Drug: Memantine Drug: Placebo (for Memantine) Phase 2

Detailed Description:

Amyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disease that affects 30,000 Americans each year. Of these 30,000 Americans, it has been suggested that up to 50% will experience cognitive and behavioral changes in the form of frontotemporal dysfunction and up to 40% will meet criteria for frontotemporal dementia (FTD). Riluzole the only FDA approved agent for ALS extends a patient's lifespan by 2-3 months, and there are no proven therapies for the cognitive changes associated with ALS. More effective therapy for this universally fatal disease is desperately needed.

Results from an open label pilot trial of 20 patients treated with memantine at 10 mg twice a day suggested that treatment with the combination of memantine and riluzole slowed ALS disease progression. This trial also showed that levels of specific protein biomarkers in the cerebrospinal fluid (CSF) at baseline correlated with the rate of disease progression. A concurrent phase II study performed by Dr. Carvalho, found no effect with similar dosing; however, the study was limited in terms of power. Comments on previous failed drug trials in ALS have raised the concern that many ALS trials study a potential therapeutic agent at only a single dose and thus may miss the potential efficacy of non FDA approved doses; therefore, this proposed study will test a higher dose of memantine, 20 mg twice a day, in a double blind, placebo controlled, randomized trial of 90 patients with ALS to determine if a therapy of memantine, especially in combination with riluzole, can slow disease progression compared to treatment with riluzole alone or no treatment. Participants who experience treatment related adverse events may undergo dose reduction or discontinuation. The primary outcome measure will be the rate of disease progression as measured by the ALS Functional Rating Scale- Revised (ALSFRS-R). In addition the investigators will examine the cognitive deficits seen in ALS patients measured by the ALS Cognitive Behavioral Screen (ALS-CBS) and the Neuropsychiatric Inventory Questionnaire (NPI-Q). Finally the investigators will examine specific validated protein serum biomarkers to determine if there is a correlation between the levels of these biomarkers and the rate of disease progression. In particular the investigators will measure the ratio of phosphorylated heavy neurofilament to Complement 3 to see if this ratio is predictive of disease progression and if the levels change during therapy with memantine.

This project will offer unique insights into this untreatable disease. If this study confirms earlier results and suggests that memantine, when used in conjunction with riluzole, significantly slows down the progression of the disease, as well as ameliorates cognitive deficits in patients with fronto-temporal dysfunction, it will set the groundwork for conducting a larger phase III trial.

Primary Outcome Measures :
  1. The Primary Comparison for Efficacy Will be Based on a Linear Mixed Effects (LME) Model Fit to the ALSFRS-R Data for the Patients Followed Over 36 Weeks. [ Time Frame: During 36 weeks of therapy ]
    The primary outcome measure will be disease progression as measured by the Amyotrophic Lateral Sclerosis Functional Rating Scale - Revised (ALSFRS-R) during the 36 weeks of therapy. The patient's rate of progression on active therapy during the 36 week treatment arm will be compared to the rate of progression of the placebo arm. The ALSFRS-R is a 12 question rating scale used to determine each participant's assessment of their capability and independence in daily activities. Possible values are from 0 to 48; higher score means better outcome.


Other Outcome Measures:
  1. Measuring the Levels of Tau, Phosphorylated Neurofilament Heavy Chain (pNFH) and the pNFH/C3 Ratio in Blood [ Time Frame: 36 weeks of treatment ]
    Preliminary data have demonstrated that there are elevated levels of Tau and pNF-H in the blood of patients with ALS as compared to healthy controls suggesting that these proteins could also be used for measuring a patient's disease progression.

  2. Slowing of Behavioral Decline in Those With FTD Characteristics Based on the NPI-Q and the ALS-Cognitive Behavioral Screen (CBS)™ [ Time Frame: 36 weeks of treatment ]
    The ALS Cognitive Behavioral Screen (ALS-CBS™) and the Neuropsychiatric Inventory Questionnaire (NPI-Q), are two neuropsychological batteries that are validated measurements of frontotemporal dementia (FTD). The ALS-CBS questionnaire rates changes perceived in the patient by the caregiver. Possible values for the Cognitive score are from 0-20, and for the Behavior score are from 0-45. A higher score means better outcome. The NPI-Q provides an informant-based assessment of neuropsychiatric symptoms and associated caregiver distress for evaluating psychopathology in dementia. Possible values for the 12 item Total NPI score are from 0-36, and for the 12 item Total Distress score are from 0-30. A lower score means a better outcome
