CRPS – Adult

Advancements In Complex Regional Pain Syndrome

Distinguished Woman

Common musculoskeletal injuries to the arms and legs can sometimes develop a chronic pain condition called Complex Regional Pain Syndrome (CRPS). The symptoms vary in intensity and in some rare cases the pain can start without trauma. To make things worse, there are no FDA-approved medications to successfully manage the condition. However, a new medication is being evaluated that has shown promise in previous research to be well tolerated and potentially effective at reducing the pain associated with CRPS.

Common Symptoms

  • Disproportionate pain compared to typical injury.
  • Limb swelling.
  • Hypersensitivity.
  • Changes in skin temperature.
  • Symptoms do not go away.

Study Treatments

The investigational medication, neridronic acid (NERIXIA®), has been studied in patients with various diseases and was recently approved in Italy for the treatment of CRPS. Treatment is administered 4 times over the course of 10 days and patients will be closely followed for 12 weeks.


  • We are seeking candidates with onset of CRPS symptoms within the past two years.
  • Ages 18+.
  • You may continue your current pain treatment program. The study medication will be added as an additional medication to help further reduce a patient’s pain level.

No Cost Study

There is no cost to participate in the study, and the study participant will receive the following:

  • Medical evaluation.
  • Investigational Medication.
  • Study Related Medical Care.
  • Compensation up to $1,360.
  • Complimentary transportation or a travel stipend.
