NCT05044507

Brief Summary

This is a multicenter study that will be conducted at approximately 20 centers. BQ 2.0 is a wearable medical device that produces and delivers non-invasive, extremely-low-intensity and low-frequency, frequency-tuned electromagnetic fields in order to stimulate neuronal networks with the aim of reducing disability and promoting neurorecovery. In this study, BQ 2.0 is intended to reduce disability in adult patients with subacute ischemic stroke, with a moderate to severe disability which includes an upper extremity motor impairment. BQ 2.0 will be used for 9 weeks in conjunction with physical and occupational therapy (PT/OT) and periodic supervision (either remote or in person) of a trained site study team member. Treatments may be administered in multiple settings (e.g. acute care hospital (ACH) or inpatient rehabilitation facilities (IRF), Skilled Nursing Facility (SNF), home or other outpatient setup). The study will enroll up to 150 adult subjects who will be randomly assigned (1:1 allocation ratio) to either active or sham study intervention using BQ 2.0.

Masking Details
This is a double-blind study, subjects and Investigators will be blinded to the device setting (Active/Sham). The study site team members receiving, storing, dispensing, preparing, and administering the study interventions will be blinded. Subjects' caregivers will also be blinded. There are no differences in the active and sham device appearance. Due to the non-invasive nature of the treatment, as well as the physical characteristic of the EMF, there is no noticeable difference between sessions conducted using an active or a sham device, facilitating full blinding of both subjects and Investigators. An independent unblinded statistician (not the study statistician) will perform the assessments described. Only the unblinded statistician and members of the DSMB will be exposed to the interim report.
