Study Set To Provide Breakthrough Treatment Alzheimers

Thursday, 26 November 2009

A ground-breaking clinical trial which could help halt the onset of advanced Alzheimer's and dramatically improve the quality of life for patients and carers has been launched in the UK.

Glasgow Memory Clinic is now enrolling patients in the CONCERT trial, a one-year international study set up to test the effectiveness of a unique investigational drug, dimebon (also known by its proposed generic name of latrepirdine), in patients currently taking Aricept (donepezil HCI tablets), the leading medication for Alzheimer's disease worldwide.

More than 1,000 patients from across western Europe, the United States, Australia and New Zealand will take part in the CONCERT trial and it is hoped that the combined medication will help stabilise the condition of those with Alzheimer's by safely improving cognition (thinking and awareness), memory, daily functioning, behaviour and the ability to care for oneself.

Glasgow Memory Clinic has already enrolled a number of patients onto the trial and still has spaces available for those who meet the eligibility criteria.

Dr Fraser Inglis, Consultant Physician and founder of the Glasgow Memory Clinic, is optimistic about the advances the trial may make in the treatment of Alzheimer's disease.

"Alzheimer's is a complex disease and while current medications may improve the symptoms for some patients for a time, often the disease continues to progress. Therefore, combination therapy may be the method to maximise clinical benefit," said Dr Inglis.

"CONCERT is an important study because dimebon is thought to work differently to current medications and this study will evaluate whether adding it to one of the most commonly used Alzheimer's medications will provide a more effective symptomatic treatment to patients, stabilising their condition and ultimately improving their quality of life.

"A cure for Alzheimer's is still many years away, however treatments that provide lasting effects, more symptomatic benefits or slow disease progression would offer meaningful benefits for patients and their carers. For this reason, there is an urgent need for patients to participate in clinical trials such as CONCERT and help advance the understanding of how Alzheimer's disease can be better treated."

The Alzheimer's Society estimates that as many as 417,000 people in the UK are living with  Alzheimer's, a devastating disease that hinders the patient's ability to remember, learn, perform daily activities and relate to others. As the baby boomer population ages, the incidence of Alzheimer's is expected to increase dramatically.

Mrs Balneaves, wife of an Alzheimer's sufferer adds: "As the wife and carer of an Alzheimer's patient, I understand fully how debilitating this disease is and how, in the majority of cases, it leaves sufferers requiring round-the-clock care and unable to interact fully with society.

"It causes untold suffering not only to the person with the disease, but also to their family and friends, and I can only welcome any research that can provide renewed hope of an improved quality of life for anyone touched by Alzheimer's."

The Glasgow Memory Clinic is based in a new £4m facility within the West of Scotland Science Park and is internationally recognised as a leading independent research organisation dedicated to finding better treatments for those with Memory Impairment, Alzheimer's disease and dementia.

Patients or caregivers interested in participating in the CONCERT trial are invited to contact the Glasgow Memory Clinic for information on eligibility and enrolment on 0141 948 0206 or http://www.glasgowmemoryclinic.com/.

About Concert

Concert (http://www.concertstudy.com/) is an international, randomised, double-blind, placebo-controlled study that will enrol approximately 1,050 patients with mild-to-moderate Alzheimer's disease at approximately 100 sites in western Europe, the United States, Australia and New Zealand. Patients on a stable dose of Aricept will be randomised to one of three treatment groups: dimebon 20 mg three times per day, dimebon 5 mg three times or placebo.

The primary endpoints are the Alzheimer's Disease Assessment Scale - cognitive subscale (ADAS-cog) and Alzheimer's Disease Cooperative Study - Activities of Daily Living (ADCS - ADL), a measure of self-care and daily function. The Concert study is sponsored by Pfizer and Medivation, Inc.

About Dimebon

Dimebon (latrepirdine) is an investigational drug currently in Phase 3 development for the treatment of Alzheimer's disease and in clinical development for Huntington disease (HD). The comprehensive Phase 3 clinical development programme for Alzheimer's disease is evaluating the potential for dimebon to be used in broad applications including use alone, in combination with existing medications and in patients at all stages of the disease.

Dimebon has a unique mechanism of action, distinct from currently available treatments. In preclinical studies, dimebon has been shown to protect brain cells from damage and enhance brain survival, potentially stabilising and improving mitochondrial function. Mitochondria are critical to brain cell functioning as they are the primary source of energy for cells. Drugs that protect mitochondria or restore their function could potentially be a valuable treatment approach in AD.
