OBJECTIVE: To analyse changes in muscle strength, physical performance and quality of life during intravenous immunoglobulin (IVIg) treatment in patients with post-polio syndrome. DESIGN: Open clinical trial.Patients: A total of 14 patients (6 women, 8 men; mean age 57 years, range 43-67 years) were included in the study. INTERVENTION: Treatment with 90 g IVIg (30 g daily for 3 days). Main outcome: Muscle strength, measured with dynamic dynamometry, muscle function, by means of performing the 6-minute walk test, and quality of life, analysed by means of the SF-36 questionnaire, were performed before and after treatment. RESULTS: For quality of life there was a statistically significant improvement for all but one of the 8 multi-item scales of SF-36 when comparing data before and after treatment with IVIg. The multi-item scale most improved was Vitality. There was no significant increase in muscle strength and physical performance. CONCLUSION: Data indicate that IVIg may have a clinically relevant effect, with an improvement in quality of life. The effect may be due to a decrease in an inflammatory process in the central nervous system, which earlier has been reported in patients with past-polio syndrome after IVIg treatment. Since a possible placebo effect cannot be ruled out, a randomized controlled study is needed.

Post-polio syndrome (PPS) is characterized by new muscle weakness, atrophy, fatigue and pain developing several years after the acute polio. Some studies suggest an ongoing inflammation in the spinal cord in these patients. From this perspective, intravenous immunoglobulin (IvIg) could be a therapeutic option. We performed a double-blinded randomized controlled pilot study with 20 patients to investigate the possible clinical effects of IvIg in PPS. Twenty patients were randomized to either IvIg 2 g/kg body weight or placebo. Primary endpoints were changes in pain, fatigue and muscle strength 3 months after treatment. Surrogate endpoints were changes in cerebrospinal fluid (CSF) cytokine levels. Secondary endpoints were pain, fatigue and isometric muscle strength after 6 months. Patients receiving IvIg reported a significant improvement in pain during the first 3 months, but no change was noted for subjective fatigue and muscle strength. CSF levels of tumour necrosis factor-alpha (TNF-alpha) were increased compared with patients with non-inflammatory neurological disorders. In conclusion, in this small pilot study no effect was seen with IvIg treatment on muscle strength and fatigue, however IvIg treated PPS patients reported significantly less pain 3 months after treatment. TNF-alpha was increased in the CSF from PPS patients. The results are promising, but not conclusive because of the low number of patients studied.

The first medical treatment of Post-Polio Syndrome
Xepol is the first pharmaceutical product to address the unmet medical need of patients suffering from Post-Polio Syndrome (PPS). Even though new infections from the poliovirus ceased in developed countries more than 30 years ago, many patients are now struggling with renewed complications from the disease. While rarely fatal, the neurological and muscular symptoms of PPS are lifelong and debilitating. There is no medical treatment besides physiotherapy and assistive devices. Approximately 30-40% of survivors of paralytic polio develop severe PPS. There are around 300,000 PPS patients in major Western markets.
The concept behind Xepol was first developed by Dr Henrik Gonzalez and Professor Kristian Borg, both scientists at the Karolinska Institute (Sweden), and is backed by strong evidence suggesting an underlying neuroinflammatory pathology. Xepol is an injectable biological product which is administered once every 9 – 12 months and down regulates the inflammatory process in the nervous system of PPS patients. It was acquired by Pharmalink as an original concept backed by preliminary positive clinical observations.
Xepol is protected by patents in major markets. In addition, market exclusivity was achieved by a US Orphan Drug Designation granted in 2006.
Given the prevalence of PPS, there is the potential to achieve orphan drug designation in all major markets.
Following positive preliminary clinical studies, Pharmalink sponsored a Phase III of Xepol in PPS. The trial clearly met one of its two primary endpoints, relating to muscle strength, and results were published in the Lancet. In a follow-on study trial, still double-blinded, a defined subset of patients met both original endpoints showing a reduction of inflammatory cytokines in the cerebrospinal fluid and a significant reduction of symptoms of PPS while also showing that Xepol is safe and well tolerated with few or no side-effects. Significant results were also shown in endpoints such as pain, walking ability and SF-36 scores.
A confirmatory Phase III study will be a further step in the development of Xepol, creating a basis for regulatory applications in the US, Europe and other potential markets. Pharmalink has prepared plans for the Phase III trial to be conducted in the US.
Pharmalink is actively seeking a partner to bring Xepol onto the market.Lancet Neurol. 2006 Jun;5(6):493-500.

BACKGROUND: Survivors of poliomyelitis often develop increased or new symptoms decades after the acute infection, known as post-polio syndrome. Production of proinflammatory cytokines within the CNS indicates an underlying inflammatory process, accessible for immunomodulatory treatment. We did a multicentre, randomised, double-blind, placebo-controlled study of intravenous immunoglobulin in post-polio syndrome. METHODS: 142 patients at four university clinics were randomly assigned infusion of either 90 g in total of intravenous immunoglobulin (n=73) or placebo (n=69) during 3 consecutive days, repeated after 3 months. Seven patients were withdrawn from the study. Thus, 135 patients were assessed per protocol. Primary endpoints were muscle strength in a selected study muscle and quality of life as measured with the SF-36 questionnaire (SF-36 PCS). Secondary endpoints were 6-minute walk test (6MWT), timed up and go (TUG), muscle strength in muscles not chosen as the study muscle, physical activity scale of the elderly (PASE), visual analogue scale (VAS) for pain, multidimensional fatigue inventory (MFI-20), balance, and sleep quality. Outcome tests were done immediately before the first infusion and 3 months after the second infusion. This study is registered with , number NCT00160082. FINDINGS: Compared with baseline, median muscle strength differed by 8.3% between patients receiving intravenous immunoglobulin and placebo, in favour of the treatment group (p=0.029). SF-36 PCS did not differ significantly between the groups after treatment (p=0.321). Differences in the subscale vitality score (p=0.042) and PASE (p=0.018) favoured the active treatment group. MFI-20, TUG, muscle strength in the muscles not chosen as the study muscle, 6MWT, balance, and sleep quality did not differ between groups. For the whole study population there was no significant change in pain, as determined by VAS. Nevertheless, patients who reported pain at the study start improved in the intervention group but not in the placebo group (p=0.037). Intravenous immunoglobulin was well tolerated. INTERPRETATION: Intravenous immunoglobulin could be a supportive treatment option for subgroups of patients with post-polio syndrome. Further studies on responding subgroups, long-term effects, and dosing schedules are needed.

Primary Outcome Measures:
Physical health was quantified using the SF-36 questionnaire scales summarized into the composite Physical Component Summary (PCS) measure.
Muscular strength was measured using a dynamometer or anelectronic grip force sensor (GRIPPIT) depending on the musclechosen.
Secondary Outcome Measures:
Functional balance was assessed by using the Timed “Up and Go” (TUG) test.
Activity pattern was assessed by the Physical Activity Scale of the Elderly (PASE).
Pain was assessed by a Visual Analogue Scale and by a pain drawing.
Fatigue was assessed using the Multidimensional Fatigue Inventory (MFI-20) questionnaire.
Vitality was assessed using the vitality subscale (VT) of SF-36 questionnaire.
Sleep was assessed using the Sleep quality scale.
Muscular strength measured by a dynamometer and an electronic grip force sensor (GRIPPIT) for those muscles not included as the primary endpoint.
Walking ability was assessed by a 6 minutes walking test.
Pulmonary capacity (vital capacity, FEV1, FEV %) was measured by a standard spirometer method.
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)
Vital signs (blood pressure and heart rate)
Study Start Date:
Estimated Study Completion Date:
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.

Immunoglobulin Responsive Chronic Pain.
Pain Research Institute, 3rd Floor, Clinical Sciences Centre, Liverpool University, Lower Lane, Liverpool, L9 7AL, UK, firstname.lastname@example.org.
INTRODUCTION: Over the last 15 years, clinical and experimental data have emerged that suggest that peripheral and central, glial-mediated neuroimmune activation is both necessary and sufficient to sustain chronic pain. Immune modulation appears to be, therefore, a possible new therapeutic option.
MATERIALS AND METHODS: The Medline database and international trial registry databases were searched using the keywords "intravenous immunoglobulin" or "IVIG," "pain" or "chronic pain," "neuropathic pain," "CRPS," "complex regional pain syndrome" or "fibromyalgia." RESULTS: Evidence from RCTs suggest that IVIG is effective to reduce pain in complex regional pain syndrome (low-dose IVIG) and post-polio syndrome (high-dose IVIG), and open trials have suggested efficacy in additional pain conditions.
CONCLUSION: IVIG therapy may emerge as a novel treatment modality for refractory cases. However, before this drug can be confidently used by clinicians, important questions need to be answered concerning optimal treatment doses, duration of treatment, and its effect on function and quality of life.
