Clinical Trial of the MiniStim PNS for Knee Pain- "FLEX" Study

Status Recruiting

Clinical Trial Summary

This is a prospective, multi-center, randomized, study in which 300 evaluable subjects will be randomized 1:1 to receive active or delayed therapy with Moments PNS. Subjects in the Delayed group will start with therapy at 3-month visit follow up. The primary endpoint is a >50% pain relief at 3-months as measured by the Visual Analog Scale (VAS) without increase in baseline pain medications, with additional measurements assessed at 3, 6, 9, 12, 24, and 36-months.

Clinical Trial Description

This is a prospective, randomized, controlled, multi-center study in which up to 300 evaluable subjects will receive MiniStim PNS. Target subjects will have chronic knee pain. Subjects will be randomized into either the active or delayed group. Devices will be activated post-op in accordance to the randomization assignment. Subjects randomized to the Active group, programming parameters will be set, and therapy will be delivered for a minimum of 2-hours per day for the duration of the study. Implanted subjects will be educated on the use of the transmitter. Programming changes can be done as needed during this time period to maximize clinical response according to pre-programmed settings. Subjects randomized to the Delayed group will begin 2-hour stimulation/day at the 3-Month visit. The primary endpoint will be at 3-Months, comparing Active vs. Delayed data from baseline data, and subjects in the Delay group will begin stimulation. At the 3-month visit, VAS will be completed and compared to baseline VAS, during this visit the safety and efficacy of the device will be assessed, and subjects in the Delayed group will be instructed to begin daily stimulation for a minimum of 2 hours a day. Subjects will be seen at 3-month intervals through the 12-Month visit for data collection and adverse event review. Subjects will continue therapy and followed for a total of 36-months with primary outcomes assessed at 3-months. Their participation in the study will end at 36-months. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
