Ziconotide as First-Line IDT
- Conditions
- Neuropathic Pain
- Interventions
- Diagnostic Test: Quantitative sensory testing
- Registration Number
- NCT03321955
- Lead Sponsor
- Albany Medical College
- Brief Summary
The primary objective of this study is to prospectively examine outcomes in 12 patients using ziconotide Intrathecal Drug Therapy(IDT) as first-line monotherapy with the use of an algorithm of slow titration for dosing. The use of Prialt has demonstrated fewer and less serious associated adverse effects as compared to IDT morphine, especially when titrated slowly. We will use an average Numerical Rating Scale as our primary outcome and the Oswestry Disability Index(ODI), Beck Depression Inventory (BDI), Pain Catastrophizing Scale (PCS), Clinical Global Impression of Change Scale including binary satisfaction measures(CGIC), Lawton-Brody Instrumental Activities of Daily Living(IADL) and Short Form-36 as secondary outcome measures.

Group Intervention Description Subjects with Painful Neuropathy Ziconotide 100 MCG(microgram)/ML Intrathecal Solution All subjects will be implanted with the Medtronic Synchromed II pump, and treated with the same algorithm for dose adjustment for painful neuropathy with Ziconotide 100 micrograms/ml. Subjects with Painful Neuropathy Quantitative sensory testing All subjects will be implanted with the Medtronic Synchromed II pump, and treated with the same algorithm for dose adjustment for painful neuropathy with Ziconotide 100 micrograms/ml.
- Primary Outcome Measures
Name Time Method Numerical Rating Scale (NRS) Baseline, 3, 4, 6, 8, 9, 10, 12 week and 4, 5, 6 and 12 months This scale allows the subject to quantify their pain numerically, with 10 being the worst pain imaginable. This scale describe subject reported pain at its worst and best in the week prior to reporting, as well as total pain on average, and at the time of documentation. The mean of these scores will be used as the primary outcome. This scale also includes a question of subject experienced global improvement in which the patient is asked to quantify their overall change in pain with 0 being no change and 10 being completely changed. Using the NRS we will calculate a responder rate, assessing percentage of patients with a 50% response in NRS
- Secondary Outcome Measures
Name Time Method Oswestry Disability Index Scale Baseline, 12 weeks, 6 month, 12 month Comprises 11 sections, this survey asks the patient to indicate the degree to which they have difficulty in daily life relating to pain.
Pain Catastrophizing Scale Baseline, 12 weeks, 6 month, 12 month This scale separates three types of catastrophizing: rumination, magnification and helplessness. Catastrophic thinking can contribute to the probability that a pain condition will be persistent over tim.
SF (Short Form) - 36 Baseline, 12 weeks, 6 month This scale utilizes 36 questions to determine overall quality of life in patients by discussing physical health, emotional health, and social engagement.
IADL(Instrumental Activities of Daily Living) Baseline, 12 weeks, 6 month, 12 month Used to assess complex functional activities of daily living, this scale extrapolates on basic activities such as ability to eat or walk, to include cooking shopping, housekeeping.
Beck Depression Inventory Baseline, 12 weeks, 6 month, 12 month 21 question survey pertaining to a patient's severity of depression. Each question is scored for 0 to 3, with 0 indicating no depression and 3 indicating the most severe depression
