Treatment of Multiple Sclerosis Using Over the Counter Inosine

March 16, 2006 updated by: National Center for Complementary and Integrative Health (NCCIH)
The purpose of this study is to determine whether raising low levels of the natural antioxidant uric acid by the administration of a precursor, inosine, has any therapeutic effect on the progression of Relapsing Remitting Multiple Sclerosis (RRMS) and secondary progressive Multiple Sclerosis (MS).

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Uric acid is a natural inhibitor of certain chemistries associated with peroxynitrite, a product of inflammation. In animal models of multiple sclerosis (MS), these chemical reactions have been associated with breakdown of the blood-brain barrier and CNS tissue damage. In addition, MS patients have serum uric acid levels that are lower than age- and sex- matched healthy individuals. The primary purpose of this study to determine whether raising low serum uric acid levels by daily oral administration of its precursor inosine has an effect on the cumulative number of newly active lesions on magnetic resonance imaging (MRI) and to evaluate the safety and tolerability of inosine in patients diagnosed with relapsing remitting and secondary progressive MS.

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

18 years to 60 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Nonpregnant, nonlactating females
  • Females of child bearing potential must have a negative human chorionic gonadotropin (HCG) test result within 60 days before the first dose of study material.
  • Males and females must practice adequate contraception, in the judgement of the investigator, during the course of the study.
  • Subjects must have a diagnosis of clinically definite Relapsing Remitting Multiple Sclerosis based on medical history, physical examination, laboratory test results, and neurologic examination. Alternatively, subjects may have clinically probable MS characterized by 1 attack and the presence of at least 4 lesions on MRI within 12 months before the initial baseline evaluation.
  • Subjects must have an Expanded Disability Status Scale (EDSS) test result of less than or equal to 5.0 within 60 days before the first dose of study material.
  • Subjects will have serum uric acid levels less than 5 mg/dl.
  • Have 1 clinical relapse in the last year

Exclusion Criteria:

  • Presence of any medical disability or laboratory test result that, in the judgement of the investigator, would interfere with assessment of the tolerability, safety, or efficacy of study material or would compromise the subject's ability to provide informed consent.
  • Evidence of active infection characterized by requiring treatment with antibiotics within 7 days before the first dose of study material.
  • Treatment with interferons, glatiramer acetate, lymphoid irradiation, cyclophosphamide, or with other immune modifying treatments within 3 months, or corticosteroids within 1 month before the initial baseline MRI assessment in this trial.
  • Recent history (within the previous 2 years) of drug or alcohol abuse.
  • Known allergy to Inosine products or history of anaphylaxis.
  • Previous randomization into this study.
  • Treatment with an investigational agent within 30 days before the first dose of study material.
