Study Details

Study Description

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.

Condition or Disease Intervention/Treatment Phase
Phase 1

Detailed Description

Chronic pain is a significant, widespread problem affecting every fifth person worldwide. Reported in 2011 by the Institute of Medicine, chronic pain affects 116 million American adults - more than the total number of individuals affected by heart disease, cancer, and diabetes combined. An estimated $635 billion each year is spent in the medical management of chronic pain and lost productivity. Better clinical methods to diagnose and localize pain are needed.

The investigators have developed a S1R-specific radiotracer, [18F]FTC-146. Using imaging approaches to assess the location of S1R in pain may provide a tool to diagnose pain generators, monitor treatment response, and aid in the selection of patients for treatment.

The goal is to use [18F]FTC-146 to image S1R expression in healthy volunteers and to compare the images to those individuals suffering from pain conditions in the following categories: (1) nociceptive pain (pain that results from tissue injury or inflammation), (2) neuropathic pain (pain that results from direct injury, disruption, impingement/compression or malfunction of the peripheral and/or central nervous system), and (3) mixed pain (pain that appears to have both nociceptive and neuropathic).

Arms and Interventions

Arm Intervention/Treatment
Experimental: Pain Patients

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
Adult participants will be injected with 5-10 mCi of [18F]FTC-146 and undergo a PET/MRI scan.
Other Names:
  • S1R
  • Experimental: Healthy Volunteers

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

    Drug: [18F]FTC-146
    Adult participants will be injected with 5-10 mCi of [18F]FTC-146 and undergo a PET/MRI scan.
    Other Names:
  • S1R
  • Outcome Measures

    Primary Outcome Measures

    1. [18F]FTC-146 Biodistribution in Healthy Volunteers [Estimated average of 3 hours]

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

    2. [18F]FTC-146 Biodistribution in Pain Patients [Estimated average of 3 hours]

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