Chronic Pain | Intrathecal Morphine Compared to Conventional Medical Management for Pain Control and Opioid-related Side Effects

Chronic Pain research study

What is the primary objective of this study?

This study compares two different ways to treat pain. The two ways are: 1. continuing to take current pain medication(s) or 2. receiving morphine, a pain medication from a drug pump (a system to deliver drug to your body) that is implanted. None of the procedures or products used in this study are experimental. The length the study will be about 25 weeks (between 5½ to 6½ months). The purpose of this study is to compare pain and opioid side effects between people who get a drug pump and people who do not get a drug pump that will stay on their current pain medication treatment.

Who is eligible to participate?

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?

Chronic Pain

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Device:SynchroMed Infusion System and Intrathecal Morphine SulfateFollowing a successful test of Intrathecal Morphine Sulfate, subjects will undergo surgery to implant the drug pump (SynchroMed Infusion System) and spinal catheter. The pump will deliver morphine directly to the spinal cord for pain control.

Other:Conventional MedicineSubjects will continue to use pain medications as prescribed by their doctor.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.
