A Multi-Center, Randomized, Controlled, Double-blind Study Evaluating Safety and Efficacy of Hemocyte Autograft for Treatment of Single-Level and Multi- Level Lumbar, Thoracic and Cervical Discogenic Pain
In Brief
A clinical study evaluating High yield pure PRP, Placebo, and 1 other intervention for Discogenic Pain. Completed, enrolled 27 participants across 7 sites.
Detailed Summary
This is a multi-center, randomized, controlled, double-blind clinical trial comparing hemocyte autograft (platelet rich plasma) to control injection (placebo) in subjects with reported cervical, thoracic or lumbar pain for at least 3 months with Pfirrmann grade changes at 7 or less and who are being considered for discography in order to identify pain generator discs in evaluation of potential surgical candidates.

Timeline
Interventions
The investigational product is hemocyte autograft derived from the subject's own blood. Subjects with a clinical diagnosis of discogenic pain had a discogram with ¼ cc to ½ cc of contrast injected by hand (leaving up to ½ cc contrast in the needle lumen and connecting tube); any concordant pain will be noted. Subjects received the injectant delineated by coordinator-provided randomization. Subjects were awake for the entirety of study treatment procedure. All subjects had blood drawn (50 cc) from any access site and double-centrifuged using the EmCyte Hemocyte Autograft system; the first spin separated the buffy coat, the second spin and subsequent siphoning separated a purified platelet sample.
Placebo injections will have saline placed in centrifuges and run for the duration required for PRP preparation. 3cc of saline will be placed in 3 cc syringes with opaque tape around the barrel to cover the fluid chamber. 1-2 cc of saline will be injected into the nucleus pulposus of each treatment level disc under fluoroscopy for lumbar; 0.5-1 cc for thoracic and 0.5-1 cc for cervical.
