Trial summary

Multiple sclerosis (MS) is a disease of the nervous system. The exact cause of MS is unknown, but it is believed to be an autoimmune condition. Autoimmune conditions are diseases that cause the body's immune system and natural defenses to attack healthy cells. Read more about this study

About this study

Official title: Open-Label Baseline vs. Treatment Trial Evaluating the Safety, Tolerability and Effect on MRI Lesion and Immunology Parameters of CGP 77116 in Patients With Multiple Sclerosis Mark

Multiple sclerosis (MS) is a disease of the nervous system. The exact cause of MS is unknown, but it is believed to be an autoimmune condition. Autoimmune conditions are diseases that cause the body's immune system and natural defenses to attack healthy cells. In the case of MS, the immune system begins attacking myelin, the cells that make up the sheath covering nerves. Without myelin nerves are unable to transmit signals effectively and symptoms occur.

Researchers are interested in testing the safety, tolerability, and effectiveness of a new therapy (CGP77116) for Multiple Sclerosis (MS). CGP77116 is a small protein similar to the protein in myelin. CGP77116 is designed to modify the immune reaction that destroys normal myelin. CGP77116 is an experimental therapy meaning it has not been approved by the U.S. Food and Drug Administration. However, in preliminary studies on animal it has been shown to be effective at modifying the autoimmune reaction associated with the development of MS.

The purpose of this study is to assess the safety and effect of CGP77116 on disease activity in patients with Multiple Sclerosis as measured by magnetic resonance imaging (MRI) and immunological studies.

The study is broken into three parts:

  1. BASELINE: in the first part of the study patients will undergo 6 MRIs over a 5 month period. During this time, patients will be evaluated based on the presence of MS lesions seen on MRI. Patients whose MS lesions are highly active will be entered into the second part of the study.

II) TREATMENT: in the second part of the study, patients with active MS lesions will begin receiving CGP77116. The drug will be given by injection once a week for one month and then once a month for 8 additional months.

III) FOLLOW-UP: in the third and final part of the study, patients will undergo an MRI every 2 months for 6 months and then every 3 months for 6 additional months. The results of the MRIs will be used to measure the effectiveness of CGP77116.

Read the detailed description

This trial will evaluate safety, tolerability and effect on cranial magnetic resonance imaging (MRI) and immune response of CGP 77116 in patients with the demyelinating autoimmune disease, multiple sclerosis (MS). The purpose of the trial is to assess whether CGP 77116 modifies inflammatory disease activity as measured by MRI and immunological techniques, and to facilitate dose selection for future pivotal trials in progressive and relapsing-remitting MS.

CGP 77116 is an altered peptide ligand (APL) designed around an immunodominant epitope of human myelin basic protein (MBP) corresponding to amino acids 83-99, for the treatment of multiple sclerosis (MS). Substitution of a key T cell receptor contact residue with alanine results in a non-stimulatory peptide analogue. Recent evidence suggests that a T cell-mediated immune response against immunodominant myelin protein peptides such as MBP (83-99) is involved in MS pathogenesis (1). MS results when the immune system is unable to keep autoreactive T cells from entering the central nervous system where they initiate demyelination of myelin sheaths. By targeting MBP autoreactive T cells, CGP 77116 may downregulate the MBP-specific immune response and lead to amelioration of MS.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing CGP 77116 in people with Multiple Sclerosis, run by National Institute of Neurological Disorders and Stroke (NINDS) at 1 site in United States.

The full registered description is in the About this study section and the official record.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 4 Mar 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00001781, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Mar 2008.
