Efficacy and Tolerability of MLC601 in Patients With Mild to Moderate Alzheimer Disease Who Were Unable to Tolerate or Failed to Benefit From Treatment With Rivastigmine

September 27, 2012 updated by: Ali Amini Harandi, Shahid Beheshti University of Medical Sciences
Current therapeutic approaches for the treatment of neurodegenerative diseases like Alzheimer disease (AD) offer limited and often transient symptomatic benefits to patients but do not mitigate the insidious loss of neuronal cells. In this trial the investigators will evaluate Efficacy and Tolerability of MLC601 as a neuroprotective in Patients with Mild to Moderate Alzheimer Disease who Were Unable to Tolerate or Failed to Benefit from Treatment with Rivastigmine.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

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

An 18-month open-label pilot study would be conducted at three university referral centres in Tehran, Iran. All patients are at least 50 years old, met the criteria for AD according to the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), and failed treatment with the cholinesterase inhibitor Rivastigmine for any reason. A baseline medical history will be taken and physical examination will be performed for all participants, and any comorbidities and concomitant therapies would be noted. Patients with controlled concomitant diseases, such as hypertension and diabetes, will be allowed to enter the study. Mini-Mental State Examination (MMSE)10 and Alzheimer disease assessment scale-cognitive sub scale11 (ADAS-cog) will be used to measure treatment efficacy. MLC601 will be prescribed as one capsule three times daily without an escalation dose. Safety and tolerability evaluations included physical examinations, electrocardiography, vital sign monitoring and laboratory testing weekly for the first 8 weeks and every 4 weeks thereafter. The MMSE and ADAS-cog will be recorded at each efficacy follow-up visit.

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.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
changes in the Mini-Mental State Examination (MMSE) relative to baseline measurements
Time Frame: every 4 weeks up to 18 months
change in the Mini-Mental State Examination (MMSE) relative to baseline measurements will be evaluated every 4 weeks up to 18 months.
every 4 weeks up to 18 months
changes in the cognitive subscale of the AD Assessment Scale (ADAS-cog) relative to baseline measurements
Time Frame: every 4 weeks up to 18 months
change in the cognitive subscale of the AD Assessment Scale (ADAS-cog) relative to baseline measurements will be evaluated every 4 weeks up to 18 months.
every 4 weeks up to 18 months

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
to measure included adverse events (AEs)
Time Frame: every 4 weeks
Safety and tolerability evaluations included physical examinations, electrocardiography, vital sign monitoring and laboratory testing weekly for the first 8 weeks and every 4 weeks thereafter. AEs were defined as any sign, symptom, syndrome or disease that occurred for the first time or worsened after baseline, whether they were considered treatment related.
every 4 weeks
measuring withdrawal rate
Time Frame: every 4 weeks
measuring any withdrawal rate among intervention group
every 4 weeks
