Masitinib in Patients With Mild to Moderate Alzheimer's Disease

September 27, 2023 updated by: AB Science

A Multicenter, Double-blind, Placebo-controlled, Randomized, Parallel-group Phase 3 Study to Evaluate the Safety and Efficacy of Masitinib in Patients With Mild to Moderate Alzheimer's Disease

The purpose of this study is to assess the safety and efficacy of masitinib for the treatment of mild to moderate Alzheimer's Disease. Masitinib will be administered as add-on therapy in patients who have been treated for a minimum of 6 months with a stable dose of cholinesterase inhibitor (donepezil, rivastigmine or galantamine) and/or memantine.

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

Actual standard treatment for mild to moderately severe Alzheimer's dementia includes acetylcholinesterase inhibitors (donepezil, rivastigmine and galantamine) and a NMDA receptor antagonist (memantine for moderate to severe Alzheimer's disease). These medications have shown to have an effect on some cognitive and non cognitive symptoms of the pathology. However, their efficacy remains limited and may decrease with time. There is an unmet medical need in this pathology. Masitinib is a selective tyrosine kinase inhibitor that is thought to exert a neuroprotective effect through its activity on mast cells and other non-neuronal cells of the central nervous system, with subsequent modulation of inflammatory and neurodegenerative processes, as well as possibly disruption of the Aβ signaling cascade via inhibition of the Fyn signaling pathway. This is a multicenter, double-blind, randomized, placebo-controlled, parallel-group study of oral masitinib. The objective of this study is to compare the efficacy and safety of masitinib at various doses versus matched placebo in the treatment of patients with mild to moderate Alzheimer's Disease. Masitinib will be administered as add-on therapy in patients who have been treated for a minimum of 6 months with a stable dose of cholinesterase inhibitor (donepezil, rivastigmine or galantamine) and/or memantine. Approximately 675 patients will be randomized into 5 treatment groups. The co-primary outcome measures are the Alzheimer's Disease Cooperative Study Activities of Daily Living score (ADCS-ADL), and Alzheimer's Disease Assessment Scale-Cognitive Subscale score (ADAS-Cog) after 24 weeks of 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

50 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Inclusion criteria include:

  1. Patient with dementia of Alzheimer's type, according to the Diagnostic and Statistical Manual of Mental Disorders criteria (DSM-IV)
  2. Patient with probable Alzheimer' disease according to the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association criteria (NINCDS-ADRDA)
  3. Patient with MMSE ≥ 12 and ≤ 25 at baseline
  4. Patient treated for a minimum of 6 months with a stable dose of cholinesterase inhibitors (donepezil, rivastigmine or galantamine) at baseline, and/or a stable dose of memantine for a minimum of 6 months at baseline, with no changes foreseen in therapy throughout the study.

Exclusion criteria include:

  1. Patient with any other cause of dementia not due to Alzheimer's disease.
  2. Patient with Alzheimer disease with severe forms of delusions or delirium (patients with light and mild forms of delusions and delirium will be allowed in the study).
