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

April 4, 2022 updated by: EIP Pharma Inc

A Double-Blind, Placebo-Controlled Two-Period 10-Week Treatment Within-Subject Crossover Study Of Cognitive Effects Of Neflamapimod in Early-Stage Huntington Disease (HD)

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).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Terminated

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The study was designed as within-subject crossover study. However, due to the Covid19 lockdowns and restrictions on clinical research, and only one subject entered the second crossover period. As a result, the baseline and outcomes are reported by the actual treatment received in the subjects during what would have been the first treatment period, i.e. placebo or neflamapimod treatment.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

30 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Exclusion Criteria:
