PANACEA Feasibility Study to Assess the Efficacy of BurstDR Spinal Cord Stimulation (SCS)

The Leeds Teaching Hospitals NHS Trust

Status: Unknown

Conditions: Pain

Treatments: Device: Spinal cord stimulation by implanted device.

Study type: Interventional

Funder types: Other

Identifiers

NCT03595241

About

To evaluate the effectiveness of Burst DR stimulation as a treatment for persistent abdominal refractory visceral pain secondary to chronic pancreatitis. Abdominal pain is a main symptom in patients with chronic pancreatitis. Patients have a background constant pain with acute episodes needing admissions. Spinal cord stimulation (SCS) is a recognised treatment for neuropathic pain. This involves placing an electric wire in the spine and the use of electricity to manage the pain. This is a pacemaker for controlling pain. Burst DR stimulation delivers a wave form which mimics the way nerves conduct electrical signals, there are short bursts or spikes of stimulation followed by short periods of rest. The key aims and objectives of this study are to evaluate the efficacy of Burst DR SCS as a treatment for persistent pain secondary to chronic pancreatitis

Enrollment: 30 estimated patients

Sex: All

Ages: 18 to 100 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• Male or female participants aged 18 years or older (no upper age limit) and willing to provide informed consent
• Participant is able and willing to comply with the follow-up schedule and protocol
• Participants diagnosed with persistent refractory visceral pain secondary to chronic pancreatitis for at least 6 months with or without dermal hyperalgesia or allodynia
• Minimum baseline pain score of 6 on eleven point NRS scale (0-10) for their visceral pain
• Previously tried and failed at least one conservative treatment for chronic pain including but not limited to pharmacological therapy, physical therapy and interventional pain procedures for persistent pain
• Been deemed suitable for the study by the pancreatic or pain MDT
• Total daily dose of opioids equivalent to ≤120mg of Morphine or 50% reduction in opioid dose. If the patients are taking more than this dose, they will be offered a referral to our opioid reduction clinic to achieve the target opioid dose and the baseline opioid will be taken as the dose on referral
• In the investigators opinion, the patient is a suitable candidate for Spinal Cord Stimulation

Exclusion criteria

• Female participants of childbearing potential who are pregnant/nursing or plan to become pregnant during the course of the trial
• Escalating or changing pain condition within the past month as evidenced by investigator examination
• Sphlanchnectomy or radiofrequency treatment within the past 6 months
• Currently has an active implantable device including pacemakers, spinal cord stimulator or intrathecal drug delivery system
• In the investigators opinion has an active infection
• Participated in another clinical investigation within 30 days
• Medical co-morbidities that preclude surgical intervention
• Patient is incapable of understanding or operating the patient programmer handset
• Patient is morbidly obese (BMI ≥ 40)
• Participant has a current or previous condition, which will probably require MRI investigation sometime in the following 2 years
• Participant has had a spinal surgical procedure or has spinal pathology that would significantly impede lead implantation at the level planned for implantation
• Participant has another persistent painful condition other than persistent refractory visceral pain secondary to chronic pancreatitis.
• History of alcohol abuse in the last year or IV drug abuse in the last three years.
• No increases of more than 40% from baseline amylase and lipases
