High Doses of 4-aminopyridine in Clinically Complete Chronic Spinal Cord

Status Active, not recruiting

Clinical Trial Summary

150 patients with clinically complete chronic spinal cord Injury will be included in a randomized, parallel, placebo controlled, multi-centric, phase III trial. Patients will be evaluated before starting the medication, and at the end of the treatment in the locomotor, sensory, grade of independence, sensitivity and control of bladder and anal sphincters, quality of life, and psychogenic erection in males. Patients will be divided randomly into two groups where one will receive placebo and the other one 4-Aminopyridine (4-AP) in a maximum of 30 weeks in increasing doses.

Clinical Trial Description

Consecutive patients with chronic AIS A tetraplegic or paraplegic with an MRI showing cord continuity will be recruited in the departments of neurology, neurosurgery or rehabilitation from hospitals of Social Security Mexican Institute (IMSS) in 8 states . Just patients who meeting inclusion criteria, will be selected for the study until reach 150. After signing an informed consent, they will be randomized into 75 for the intervention arm and 75 for the placebo arm. All patients will receive capsules for daily consumption according to their assignment. They will receive ascending doses of the drug starting with 10 milligrams and progressively increasing every 2 to 4 weeks 10 mg until reaching the maximum dose proposed according to weight (maximum 1 mg/kg/d). Questionnaires and functional evaluations will be administered at the beginning of the study, and at the end of the treatment to evaluate the efficacy. The evaluations include the International Standards for Neurological Classification of Spinal Cord Injury motor and sensory Scale, the Spinal Cord Injury Independence Measure (SCIM III), quality of life (SF-36), sphincter bladder/anal sensation/control in both genders and psychogenic erection in males as primary outcomes. After the follow-up period, all test results will be analyzed and compared to determine the efficacy and safety of 4-aminopyridine. The Mann-Whitney U and Chi-square test will be used for statistical analysis. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
