Real-world Data Analysis of REN Treatment in Adolescence With Migraine

The REN device (Nerivio by Theranica, Israel) is a neuromodulation device approved by the FDA for acute treatment of migraine in patients of 12 years old and above (1-4). It is a wearable device applied to the upper arm. It stimulates C and Aδ noxious fibers using a modulated, symmetrical, biphasic, square pulse with a pulse width of 400 μs, modulated frequency of 100-120 Hz, and up to 40 mA output current which the patient can adjust. The REN device is operated by a designated app that is downloaded to the user's phone prior first use of the Nerivio device

As part of the sign-up process to the Nerivio app, all patients accept the terms of use which specify that providing personal information is done of their own free will and that their de-identified data may be used for research purposes. Users are not obligated to provide personal information and could treat without providing any feedback. The app includes a secured, personal migraine diary, which enables patients to record and track their migraines and other headaches. At the beginning of each treatment, and again 2 hours after the start of treatment, patients are prompted to record their symptoms, including pain level (none, mild, moderate, severe), functional disability (No limitation, Some limitation, Moderate limitation, Severe limitation), and an indication of which medications, if any, were taken within that 2-hour time window.

Post-marketing surveillance is designed to assess the efficacy and safety in larger and more diverse populations and in various real-world environments and situations. As a digital therapeutic device (i.e., electroceutical), the REN device enables prospective collection of electronic patient-reported outcomes in real-world clinical practice.

Recently, Real World Evidence (RWE) papers of Nerivio usage in adults were published (5-6). these papers demonstrated the safety and efficacy of the Nerivio device in a large-scale population using the accumulated data gathered by diary within the Nerivio app.

This post-marketing RWE study investigates the efficacy of the Nerivio treatment using the following outcomes:

• - Reduction in headache pain 2h post-treatment
• - Improve in functional disability
• - A standalone treatment vs combination with other therapies
• - Safety profile (in terms of device-related adverse events)

Together, these four objectives provide a comprehensive evaluation of efficacy, drug-device interactions, dose stability, and safety, in a large real-world dataset of over XXXXX treatments in the migraine adolescent population.
