Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
The investigators hypothesize that individuals with auto-antibodies targeting neuronal antigens (TS-HDS and FGFR3) and confirmed evidence of small fiber neuropathy (by skin biopsy analysis of intra-epidermal nerve fiber density) will have an improvement in both nerve fiber density and pain after treatment with immune globulin.
The co-primary endpoints will be a change in neuropathic pain (by VAS pain score) and a change in intra-epidermal nerve fiber density (by punch skin biopsy).
The data gained from this pilot study will establish a rationale, with an appropriate screening test, for the use of immune globulin for the treatment of small fiber neuropathy.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
However, despite this broad differential at least 30% of cases of small fiber neuropathies remain idiopathic. There is therefore a growing interest in the potential for using IVIG in small fiber neuropathy without direct proof that the disorder is caused by immune reactions. We have recently uncovered two novel autoantibodies, TS-HDS and FGFR-3, that are targeted again peripheral neural structure. TS-HDS is a disaccharide component of glycosylation of heparin and heparin sulfate.
Patients with elevated levels of IgM against TS-HDS display clear small fiber loss with IgM deposits around the outside of medium- \& larger-sized capillaries with C5b-9 complement deposits. FGFR-3 is a secreted cell surface receptor; genetic defects of FGFR-3 are linked to achrondroplasia and other bony abnormalities.
The antibodies to TS-HDS and FGFR-3 are detected in up to 20% of patients with otherwise idiopathic small fiber neuropathy, but are rare in patients without small fiber neuropathy.
Dr. Levine (a co-investigator on this project) recently presented 3 cases of small fiber associated with elevated levels of auto-antibodies to TS-HDS or FGFR-3 who were treated with IVIG at 2 gm/kg/month for 6 months. He examined skin biopsies for intra-epidermal nerve fiber density and patient self-reported pain scores at baseline and after six months of therapy. All 3 cases showed marked improvement in pain scores. The average reduction in pain was 54%. In addition there was a clear increase in the intra-epidermal nerve fiber density (IENFD) after 6 months of therapy. Pre-treatment IENFD was 1.6, 1.7, and 2.4 at the calf. After 6 months of therapy the IENFD was 8.4, 5.7, 3.3 respectively (these are clinically significant improvement in nerve fiber density.
The investigators believe these anecdotal cases suggest that TS-HDS and FGFR-3 antibodies may be a marker for a group of SFN patients that are immune mediated and may respond to IVIG. (This case series was presented as a poster at the American Academy of Neurology meeting in 2017)

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
0.9% Sodium Chloride
The study will include a total 20 individuals. Subjects will be randomized equally to treatment or placebo. The placebo will consist of 0.9% Sodium Chloride per day over 2 days. Followed by 0.9% Sodium Chloride over 1 day every 3 weeks for a total of 6 treatments. Participants who are randomized to placebo will receive the same volume as they would if they were randomized to IVIG (i.e.: as if receiving IVIG at 2gm/kg) through a peripheral IV line.
0.9% Sodium Chloride
Sodium Chloride (also known as saline) is a solution of sodium chloride, or salt, and sterile water.
Intravenous Immunoglobulin
The study will include a total 20 individuals. Subjects will be randomized equally to treatment or placebo. Treatment will consist of IVIG administered at an initial dose of 2 grams/kg over 2 days followed by 1 gram/kg over 1 day every 3 weeks for a total of 6 treatments
Intravenous immunoglobulin
Gamunex-C \[immune globulin injection (human) 10% caprylate/chromatography purified\] is a sterile solution of human immune globulin protein.
