Efficacy and Safety of Xepol (Human Immunoglobulin) in Subjects With Post-Polio Syndrome (PPS)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00160082

Brief Summary:
The primary objective was to assess the effect of Xepol compared to placebo on physical health and on muscle strength in subjects with post-polio syndrome.The secondary objective was to assess the effect of Xepol compared to placebo on functional balance, activity patterns, pain, fatigue, sleep, vitality, muscular strength, pulmonary capacity, walking ability, balance and safety.

Condition or disease Intervention/treatment Phase
Post Polio Syndrome, PPS Drug: Xepol Not Applicable

Detailed Description:

Study Rationale:

In an earlier open and non-controlled study in 10 patients with PPS, Xepol was given during three days. The patients showed improvements in muscular strength and co-ordination and a decrease in pain. The aim of this study was to investigate if these findings can be confirmed in a larger, double-blind, randomised and placebo controlled study.

There are no simple clinical findings and specific laboratory changes that can be used to indicate the severity and progress of PPS. Different self-reporting questionnaires and objective measures of disability have often been used in clinical studies including SF-36 questionnaire, muscle strength measurement and walking test. The primary and secondary variables in this study were based on the clinical experience and literature reviewed.

Study Type : Interventional  (Clinical Trial)
Enrollment : 124 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double
Primary Purpose: Treatment
Official Title: Efficacy and Safety of Xepol (Human Immunoglobulin) in Subjects With Post-Polio Syndrome (PPS): A Randomized, Two-Arm, Parallel, Double-Blind, Multi-Centre, Placebo Controlled Study
Study Start Date : January 2001
Study Completion Date : May 2003

Primary Outcome Measures :
  1. Primary endpoints:
  2. Physical health was quantified using the SF-36 questionnaire scales summarized into the composite Physical Component Summary (PCS) measure.
  3. Muscular strength was measured using a dynamometer or anelectronic grip force sensor (GRIPPIT) depending on the musclechosen.

Secondary Outcome Measures :
  1. Secondary endpoints:
  2. Functional balance was assessed by using the Timed "Up and Go" (TUG) test.
  3. Activity pattern was assessed by the Physical Activity Scale of the Elderly (PASE).
  4. Pain was assessed by a Visual Analogue Scale and by a pain drawing.
  5. Fatigue was assessed using the Multidimensional Fatigue Inventory (MFI-20) questionnaire.
  6. Vitality was assessed using the vitality subscale (VT) of SF-36 questionnaire.
  7. Sleep was assessed using the Sleep quality scale.
  8. Muscular strength measured by a dynamometer and an electronic grip force sensor (GRIPPIT) for those muscles not included as the primary endpoint.
  9. Walking ability was assessed by a 6 minutes walking test.
  10. Pulmonary capacity (vital capacity, FEV1, FEV %) was measured by a standard spirometer method.
  11. Balance was assessed as postural sway velocity and the subject's ability to voluntarily sway to various locations in space (NeuroCom Balance Master) or balance assessed by static and dynamic posturography (Chattecx® balance system)
  12. Adverse events
  13. Vital signs (blood pressure and heart rate)
  14. Physical examination
  15. Laboratory tests

  3. Confirmed polio by EMG in the lower extremities in at least two of the following major muscle groups; musculi quadriceps, gastrocnemicus and tibialis anterior. (Two affected muscle groups in the same extremity were accepted).
  4. Subjectively increased muscular difficulties or pain after a period of at least 15 years functional stability.
  5. A muscle that had deteriorated within the last five years, and had 20-75 % of the muscle strength compared to age matched normal population when measured by a dynamometer or an electronic grip force sensor (GRIPPIT).
  6. Stable weight (defined as weight change <7 kg) during the last five years.
  7. Body Mass Index (BMI) £ 29 kg/m2.
  8. Subjects capable to understand given information and had signed the Informed Consent Form after full discussion of the research nature of the treatment and its risks and benefits.

Exclusion Criteria:

  1. Known or suspected intolerance to trial product or related products (e.g. sorbitol, glucose and fructose).
  2. Selective IgA deficiency.
  3. Inability to walk with walking aids.
  4. Any active malignancy, history of active malignancy or treatment for malignancy during the last three years.
  5. Disabling pain from extremities or skeletal system due to previous fracture(s), arthritis or other reasons not related to PPS.
  6. Subjects who received or who within 12 weeks prior to enrolment received any immunosuppressive/ systemic corticosteroid treatment (topical corticosteroids excluded).
