Within Subject Crossover Study of Cognitive Effects of Neflamapimod in Early-Stage Huntington Disease

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT03980938
Recruitment Status : Terminated (Due to the long delay because of COVID-19 and results from another study suggesting a higher dose may be more beneficial, EIP Pharma decided on October 15th, 2020, to end the trial prematurely.)

Brief Summary:
This is a double-blind, placebo-controlled 2-period 10-week treatment within-subject crossover study of neflamapimod in early-stage Huntington disease (HD). The primary objective is to determine whether neflamapimod can reverse hippocampal dysfunction in patients with early-stage HD, as assessed by the virtual water-maze-test for evaluating spatial learning and selected tests on the Cambridge Neuropsychological Test Automated Battery (CANTAB).

Primary Outcome Measures :
  1. the effects of administration of neflamapimod on hippocampal function, as assessed in [ Time Frame: 20 Weeks ]
    Latency during the learning phase of virtual Morris Water Maze (MWM).l MWM (hidden platform training) during the neflamapimod-treatment period compared to that during the placebo-administration period.

Secondary Outcome Measures :
  1. Additional assessment of hippocampal function by MWM [ Time Frame: 20 Weeks ]
    Percent of time spent in the correct quadrant during MWM probe test during the neflamapimod-treatment period compared to that during the placebo-administration period.

  2. To evaluate the effects of neflamapimod on the Cambridge Neuropsychological Test Automated Battery (CANTAB) paired associates learning task. [ Time Frame: 20 Weeks ]
    Number of overall errors in the CANTAB paired associates learning task, in addition to larger battery, during the neflamapimod-treatment period compared to that during the placebo-administration period.

  3. To evaluate tolerability and safety of neflamapimod in subjects with HD. [ Time Frame: 20 Weeks ]
    Safety as determined by the number of related adverse events and general tolerability reported during the neflamapimod treatment period compared to the placebo administration period.

  2. Diagnosis of any other ongoing central nervous system condition other than HD, including, but not limited to, vascular dementia, dementia with Lewy bodies, and Parkinson's disease.
  3. Suicidality, defined as active suicidal thoughts within 6 months before Screening or at Baseline, defined as answering yes to items 4 or 5 on the Columbia-Suicide Severity Rating Scale (C-SSRS), or history of suicide attempt in previous 2 years, or, in the Investigator's opinion, at serious risk of suicide.
  4. Ongoing major and active psychiatric disorder, moderate to severe depressive symptoms, and or other concurrent medical condition that, in the opinion of the Investigator, might compromise safety and/or compliance with study requirements.
