Mainstay Medical International plc (“Mainstay” or the “Company”, Euronext Paris: MSTY.PA and Euronext Growth operated by Euronext Dublin (MSTY.IE), a medical device company focused on bringing to market ReActiv8, an implantable restorative neurostimulation system to treat disabling Chronic Low Back Pain, today announced that on 10 December 2019 the Company completed a Day 100 meeting with the U.S. Food and Drug Administration (FDA) regarding a Pre-Market Approval (PMA) application submission for ReActiv8.
Jason Hannon, CEO of Mainstay, said: “We appreciate the opportunity to meet with FDA to discuss their review of the data we included in the PMA. The productive dialogue will help us submit an amendment to the PMA to reflect FDA’s feedback. We continue to expect a decision regarding approval around the end of 2020.”
FDA generally meets with the PMA sponsor approximately 100 days after filing of the PMA for the purpose of discussing the status of the review of the application. Prior to the meeting, FDA provided Mainstay with its initial feedback on the PMA, consisting of questions regarding the data included in the PMA and the interpretation of such data. The Company currently has no plans to conduct another premarket pivotal IDE trial for ReActiv8.
Mainstay will include the information requested by FDA in an amendment to the PMA, which the Company expects to file in the first quarter of 2020.

The Company is headquartered in Dublin, Ireland.

About the ReActiv8-B Study
The ReActiv8-B Study is an international, multi-center, prospective, randomized, sham-controlled, blinded trial with one-way crossover conducted under an Investigational Device Exemption (IDE). In summary, this means that eligible patients had baseline data collected and then following verification that the enrollment criteria were met, ReActiv8 was implanted. At the 14-day post implant follow up visit, half the patients were randomized to receive appropriately programmed stimulation (the treatment arm), and half were randomized to receive sham stimulation/low stimulation (the control arm). Information about the study can be found at https://clinicaltrials.gov/ct2/show/study/NCT02577354.
About Chronic Low Back Pain
One of the root causes of CLBP is impaired control by the nervous system of the muscles that dynamically stabilize the spine. ReActiv8 is designed to electrically stimulate the nerves responsible for contracting these muscles to improve dynamic spine stability, allowing the body to recover from CLBP.
People with CLBP usually have a greatly reduced quality of life and score significantly higher on scales for pain, disability, depression, anxiety and sleep disorders. Their pain and disability can persist despite the best available medical treatments, and only a small percentage of cases result from an identified pathological condition or anatomical defect that may be correctable with spine surgery. Their ability to work or be productive is seriously affected by the condition and the resulting days lost from work, disability benefits and health resource utilization put a significant burden on individuals, families, communities, industry and governments.

CAUTION – in the United States, ReActiv8 is limited by federal law to investigational use only.
