Trial design
CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Efficacy
Investigate the efficacy of IVIG treatment for pain alleviation in patients with well-defined idiopathic sensory neuropathy
Secondary objectives 6
- Investigate the efficacy of IVIG functional level and quality of life in well-defined idiopathic sensory neuropathy
- Chart the frequency of anti- FGFR3 antibodies in well-defined idiopathic sensory neuropathy
- Chart predictors of response to IVIG treatment, including anti- FGFR3 antibodies and clinical features, in well-defined idiopathic sensory neuropathy
- Implement the use of individual N-of-one trials
- Implement the use of digital home-monitoring of patient-reported outcome measures (PROMS) to evaluate IVIG response (use of digital home-monitoring will not be researched as part of this trial, but rather will be implemented as a tool to collect data)
- Chart side-effects of IVIG treatment in patients with idiopathic sensory neuropathy
