Clinical Trial Summary

This study is based on a 4-week double-blind, randomized, controlled, parallel design investigation to investigate the impact of intermittent negative pressure on spasticity and pain in people with multiple sclerosis (pwMS) (NCT05562453). The investigational device (FlowOx2.0™) is composed of a Pressure Chamber and a Control Unit (and disposable parts). All subjects will receive the same pressure chamber but be randomized to either a Control Unit that generates intermittent negative pressure (INP) of - (minus) 40 mmHg or a Control Unit that generates INP of - 10 mmHg. FlowOx2.0™ generating -40 mmHg is the investigational device, and FlowOx2.0™ generating -10 mmHg, is the comparator device. After the initial 4-week double-blind period (NCT05562453), all participants will be offered the -40mmHg control unit to be used during a 6-months optional extension part. The participants who volunteer to continue in the 6-months optional extension part will be included in this study.


Clinical Trial Description

FlowOx2.0™ is a commercially available device for home treatment of peripheral arterial disease. It is designed to be used at home by patients and has been shown to cause rapid changes in blood flow velocity in the treated leg. Recently, individuals with multiple sclerosis have reported a positive impact on their self-perceived spasticity and pain levels. The study will recruit patients from Norway, Sweden, and Denmark. All subjects will be instructed to treat the most affected leg for 60 minutes per day, preferentially in the evening. The same leg should be treated throughout the study period. A 4-week double-blind part (NCT05562453) is followed by this open investigation in which all randomized subjects that have completed the main part are offered to continue for an additional 6 months using the active device (INP of - 40 mmHg). ;
