NCT03556137

Brief Summary

Several studies have implicated involvement of sigma-1 receptors (SR1s) in the generation of chronic pain, while others are investigating anti SR1 drugs for treatment of chronic pain. Using \[18F\]-FTC-146 and positron emission tomography/magnetic resonance imaging (PET/MRI), the investigators hope to identify the source of pain generation in patients with chronic pain. The purpose of this study is to compare the uptake of \[18F\]FTC-146 in healthy volunteers to that of individuals suffering from chronic pain.

Outcome Measures

Primary Outcomes (2)

  • [18F]FTC-146 Biodistribution in Healthy Volunteers

    Biodistribution of \[18F\]FTC-146 represented as Standardized Uptake Value max (SUVmax) in healthy volunteers.

    Estimated average of 3 hours

  • [18F]FTC-146 Biodistribution in Pain Patients

    Biodistribution of \[18F\]FTC-146 represented as Standardized Uptake Value max (SUVmax) in pain patients.

    Estimated average of 3 hours

Study Arms (2)

Pain Patients

EXPERIMENTAL

Individuals suffering from nociceptive pain, neuropathic pain, and mixed pain (pain that appears to be both nociceptive and neuropathic) and undergo a \[18F\]FTC-146 PET/MRI scan.

Drug: [18F]FTC-146

Healthy Volunteers

EXPERIMENTAL

Individuals who do not have pain and undergo a \[18F\]FTC-146 PET/MRI scan.

Drug: [18F]FTC-146

Interventions

Adult participants will be injected with 5-10 mCi of \[18F\]FTC-146 and undergo a PET/MRI scan.
