Plain English Summary

Background and study aims
Alzheimer’s disease (AD) is the most common type of dementia. It’s a condition that results in a loss of mental ability due to the gradual death of brain cells. Brain inflammation may play a role in the development and progression of AD and poor memory in general. The TNF (tumour necrosis factor) alpha protein controls the body’s inflammatory response; it is increased in AD and is linked with progression of the disease. Cimzia is a medicine that is used to treat inflammatory diseases, such as rheumatoid arthritis by reducing the inflammatory response. Here, we want to find out if Cimzia reduces brain inflammation.

Who can participate?
Adults aged between 50-90 that have a mild cognitive impairment due to AD. They must also have a study partner – anyone who spends more than 8 hours a month in their company.

What does the study involve?
Participants are randomly allocated into one of two groups. Those in group 1 are given Cimzia for up to a year. Those in group 2 are given a placebo for the same time period. The drug is given as an injection once every two weeks; participants and their study partners receive training on how to administer it. Each participants general health and memory is checked over a series of 7 sessions over the course of the study. Tests include blood and memory tests, a chest X-ray, MRI scan of the brain and PET scan. A PET scan is also referred to as a brain scan. Here, we give each participant a radioactive tracer. This is an extremely small dose of a drug that is radioactively tagged so that its movements around the body can be seen. The tracer is injected and the brain then looked at by the PET scan.

What are the possible benefits and risks of participating?
Like all medicines, Cimzia can cause side effects, although not everybody gets them. They include skin rashes, fever, allergic reactions, and reduced production of blood cells. There have been reports of cancers which may be related to taking Cimzia. These include cancers of the blood and lymphatic system (including lymphoma, which is a tumour of the lymph nodes, and leukaemia), solid organ tumours and non-melanoma skin cancers. Cimzia may decrease the participants ability to fight infection. Each participant is monitored carefully during the study for possible side effects.

Where is the study run from?
The Memory and Assessment Research Centre (MARC) at Moorgreen Hospital (Southampton)

When is the study starting and how long is it expected to run for?
November 2014 to November 2017

Study information

Scientific title

A double-blind, placebo-controlled study of the effect of a TNFα antibody, certolizumab pergol (Cimzia), on microglial activation in amyloid PET positive patients with mild cognitive impairment due to AD-Intermediate likelihood (INMiND-01)

Acronym

INMiND

Study hypothesis

In MCI (mild cognitive impairment) due to AD (alzheimer’s disease), systemic inflammation and elevated systemic levels of TNF-alpha cause partially activated, or primed, microglial cells, to become fully activated, which can be modulated by the administration of a peripheral TNF-alpha antibody, certolizumab pergol (Cimzia).

Condition

MCI (Mild Cognitive Impairment) due to AD (Alzheimer's disease)

Intervention

Following the screening period, subjects will receive certolizumab pegol (Cimzia) or placebo. Subjects will have a 50% chance of receiving Cimzia and a 50% chance of receiving placebo.

1. Subjects receiving Cimzia will receive a loading dose of 400mg of certolizumab pegol at base-line, week 2 and week 4. The loading dose will be given as two subcutaneous injections of 200mg each.

2. Subjects receiving placebo will receive an imitation loading dose of placebo at base-line, week 2 and week 4, given as two subcutaneous injections of the placebo.

The subjects will attend for a safety visit at week 4, after receiving the third of the loading doses of Cimzia or placebo. Thereafter, the subjects receiving Cimzia will receive a two weekly maintenance dose of 200mg of certolizumab pegol, given as a two weekly subcutaneous injection of 200mg of certolizumab pegol from week 6 to week 52 inclusive, and the subjects receiving placebo will receive an imitation two weekly subcutaneous injection of the placebo from week 6 to week 52, inclusive.

Subjects who receive the final dose of the study medication at week 52 will be asked to attend a follow up visit at week 54, for a full safety check. Subjects with unresolved Adverse Reactions or unresolved Serious Adverse Events will be followed up until the problems have resolved, by means of unscheduled clinic visits and/or telephone consultations, as clinically indicated.
