Study Description

Brief Summary:

This is an open-label randomized controlled tria testing if an improvement in cardiovascular fitness can improve quality of Life and reduce seizure frequency in patients with refractory epilepsy.. Before the intervention each subject will undergo an evaluation of baseline cardiovascular fitness. Patients will be randomized into two groups One group will listen to a relaxation tape 5 days per week for 6 months and the other group will receive a ergometric cycle and perform a predetermined level of exercise per day , 5 days per week for 6 months. Randomization will be conducted an external randomization center based on a sequence of random numbers.

Changes in concomitant antiepileptic drugs (AED) treatment during the study will be minimized, and restricted to AED changes deemed to be necessary to address AED-related toxicity.

Medical examination; body weight; fitness test, including ECG and BP measurements, seizure frequency; adverse effects (unstructured interview); details of concomitant concomitant treatment, mood assessment by using the Hospital Anxiety and Depression Scale-Anxiety (HADS); health related quality of life (RAND-36), E4-data downloading, will be done at baseline and after 6 months

Primary endpoint: Proportion of patients with at least 50% seizure reduction

Secondary endpoints: Median percent reduction in seizure frequency, HADS score, RAND-36 score, fitness score; adverse events, changes in concomitant AED treatment, E4 data

Detailed Description:

Objectives

The primary objective of this study is to assess the effect of a 6-month course of standardized physical exercise, added on to pre-existing stable AED treatment, on seizure frequency in patients with epilepsy aged 16 to 65.

Secondary objectives include the assessment of the effect of a 6-month course of standardized physical exercise, added on to pre-existing stable AED treatment, on (i) depressive and anxiety symptom scores; (2) health-related quality of life; (3) adverse

events.

Study design

Open-label randomized controlled trial. Before the intervention each subject will undergo an evaluation of cardiovascular fitness using the cycle ergometric test and his/her work level ((Wmax/kg) transformed into a stanine (1-9) score. Patients will be randomized into two groups by applying a stratification procedure which will allow a similar proportion of patients with high fitness (stanine score 5 to 9) and low fitness (stanine score 1 to 4) in both groups. Randomization will be conducted by telephone through an external randomization center based on a sequence of random numbers.

Of the two randomized groups, one (Intervention group) will receive a course of standardized physical exercise for at least 5 days per week while the other group (control group) will randomize to listening to a computerized disc (CD) on muscular relaxation..

Changes in concomitant AED treatment during the study will not be allowed unless for adverse events related to the AEDs.

Study procedures

Patients considered to be eligible for the study will undergo initially a 4-week prospective baseline to ascertain baseline seizure frequency. After confirming their eligibility based on seizure frequency recording, patients will be examined by a study physician and by a physical therapist who will conduct an ergonomic test with a stationary bicycle under ECG and blood pressure monitoring to determine the level of cardiovascular fitness required for stratification. Thereafter the patients will be randomized to the intervention and the control group.

The intervention group will receive a course of standardized physical exercise designed to fulfill the Swedish recommendations (FYSS) on exercise for disease-prevention (150 min per week of average intensity); at least 5 days per week for 6 months using a bicycle ergometer for 30 minutes a day. An individually adjusted workload will be determined by the physical therapist to achieve moderate intensity workout based on maximal oxygen uptake (VO2)max and percentage of maximal heart rate. Patients in the other group (control group) will be randomized to listen to a CD on muscular relaxation every day for 20 minutes and continue with their usual lifestyle. At enrollment, subjects randomized to the intervention group will be provided with a bicycle ergometer. requirements) as well parameters related to seizure activity.

The following evaluations will be conducted at the times indicated, which correspond to hospital visits:

Time 0 (enrollment): Medical examination; body weight; fitness test (Åstrand submax test, which is a submaximal test of aerobic fitness.), including ECG and BP measurements, seizure frequency (last 4 weeks); adverse effects (unstructured interview); details of concomitant concomitant treatment, mood assessment by using the Hospital Anxiety and Depression Scale-Anxiety (HADS); health related quality of life (RAND-36).

Month 1, 2, 3, 4 and 5: Seizure frequency (recorded daily on seizure calendars), adverse effects (unstructured interview); body weight; details of concomitant treatment, E4-data downloading, advice on exercise from physical therapist.

Month 6: Medical examination; body weight; fitness test, including ECG and BP measurements, seizure frequency; adverse effects (unstructured interview); details of concomitant concomitant treatment, mood assessment by using the Hospital Anxiety

and Depression Scale-Anxiety (HADS); health related quality of life (RAND-36), E4-data downloading,

Any additional testing (e.g. EEG, laboratory tests) may be performed as considered clinically indicated by the treating physician.

Sample size and statistical analysis

Assuming that 40% of patients in the intervention group vs. 20% of patients in the control group have a 50% or greater reduction in seizure frequency compared with baseline, 79 patients per group provide 80% power to identify a difference between groups at a significance level of 0.05. To account for potential dropouts, a total of 100 patients per group will be randomized.

The primary analysis will be intent-to-treat (ITT) using "The Last Observation Carried Forward " (LOCF) extrapolation when appropriate. Per-protocol analysis (PPT) will exclude patients discontinuing prematurely the study and patients with less than 75% compliance with exercise requirements.

Ethical aspects

The study protocol has been approved by the Ethics Committees of Gothenburg in behalf of the participating centers. Before the study, all patients will be informed about the objectives and implications of the study, and will be asked to sign an informed consent form.

Outcome Measures

Primary Outcome Measures :

Proportion of patients with at least 50% seizure reduction [ Time Frame: Change from baseline at 6months ]
Determined by seizure diary

Secondary Outcome Measures :

Change in anxiety and depression ratings [ Time Frame: Change from Baseline at 6 months ]
Reduction in Hospital Anxiety and Depression Scale (HAD) scores.The HADS is a fourteen item scale that generates ordinal data. Seven of the items relate to anxiety and seven relate to depression. Each item on the questionnaire is scored from 0-3. A total score can be between 0 and 21 for either anxiety or depression. A lower score indicates less depression or anxiety: a cut-off point of 8/21 indicates the presence of anxiety or depression
Change in Health-Related Quality of Life [ Time Frame: Change from Baseline at 6 months ]
Improvement in "RAND-36 -Measure of Health Related Quality of Life" version called Item Health Survey (Version 1.0) score. There are 8 domains with 36 items in total. The eight health concepts are: physical functioning, role limitations caused by physical health problems, role limitations caused by emotional problems, social functioning, emotional well-being, energy/fatigue, pain and general health perceptions. All items are scored so that a high score defines a more favorable health state. In addition, each item is scored on a 0 to 100 range so that the lowest and highest possible scores are 0 and 100, respectively. Scores represent the percentage of total possible score achieved. In a second step, items in the same scale are averaged together to create the 8 scale scores. Scores represent the percentage of total possible score achieved.
Reduction in adverse event reporting [ Time Frame: Improvement from baseline at 6 months ]
