FDA Panel Meeting for SpinalMotion’s metal-on-metal disc is cancelled without explanation
KINEFLEX FDA PANEL MEETING CANCELLED (Orthopedics This Week)
SpinalMotion, Inc.’s two-day FDA orthopedic panel meeting scheduled July 24 and 25, 2013 has been cancelled.
The FDA announced the cancellation on July 11 without comment. The company told us they have no comment on the cancellation.
The company was to present evidence of the safety and effectiveness of the Kineflex/C Cervical and the Kineflex Lumbar Artificial Discs.
The Kineflex/C is a metal-on-metal (cobalt chrome molybdenum alloy) cervical total disc replacement device. The device is indicated for reconstruction of the intervertebral disc at one level from C3-C7 following single-level discectomy for intractable radiculopathy or myelopathy due to a single-level abnormality localized to the disc space.
The Kineflex Lumbar disc is a metal-on-metal (cobalt chrome molybdenum alloy) lumbar total disc replacement device. The device is indicated for reconstruction of the intervertebral disc at one level (L4-L5 or L5-S1) following single-level discectomy for lumbar degenerative disc disease (DDD) where DDD is defined as discogenic back pain with degeneration of the disc as confirmed by patient history, physical examination, and radiographic studies.
The company received IDE (Investigation Device Exemption) approvals from the FDA in 2005 to commence studies. The cervical trial involved over 20 U.S. sites. The lumbar trial also involved over 20 U.S. sites, and was a randomized study comparing the disc to another FDA approved lumbar artificial disc. Both trials required a two-year follow-up period.
In June 2007 the company completed enrollment of its cervical clinical trial. Enrollment in the company’s first IDE clinical trial, evaluating the lumbar disc was completed in 2006.
On March 20, 2012 the company announced that it received CE Mark for two sub-5mm Kineflex/C cervical total disc replacements.
The company conducted the IDE clinical study of the cervical disc compared to anterior cervical discectomy and fusion in the U.S., and submitted its premarket approval (PMA) application in 2010. A cervical disc paper was selected for the Best Papers section at the 2010 North American Spine Society’s Annual Meeting.
In October 2010 the company announced it completed enrollment in an international clinical study evaluating the lumbar disc inserted via a minimally invasive lateral approach.
