Summary:

Inhibitors of the epigenetic enzymes histone deacetylases (HDACs) produce analgesic responses and are therefore therapeutic targets for pain. The research team recently resolved a PET imaging agent, [11C]Martinostat, that selectively binds to a subset of HDAC enzymes. A series of initial proof-of-concept clinical validation studies will be conducted to evaluate whether [11C]Martinostat PET is a sensitive biomarker to detect the typical (axial) chronic low back pain (cLBP). The research team will validate [11C]Martinostat PET’s ability to differentiate subtypes of pain by comparing axial cLBP and other cLBP patients with radiculopathy and longitudinally study subacute LBP patients (sLBP) to investigate whether there is a unique imaging signature that differentiates patients who develop cLBP and those who recover from low back pain. Using [11C]Martinostat to understand HDAC expression changes in chronic pain patients will validate an epigenetic drug target, refine patient selection based on HDAC expression, and facilitate proof of mechanism in developing novel analgesics.
