About

Flowonix Prometra® II Programmable Pump may require a smaller dose of drug when converting from other commercially available intrathecal drug delivery systems (IDDS).

Full description

This open-label, non-randomized, single-blind, multi-center study is designed to evaluate effects of a planned 20% dose reduction when converting to valve-gated from a peristaltic pump. Study participants will be blinded (single blind) to the dose reduction aspect of this trial and must remain blinded to this dose reduction information throughout the trial in an attempt to provide an unbiased assessment of the pain encountered by the patient with their pain pump medications used.

This study will compare the historical pain medication dose and pain scores using the peristaltic pump at baseline as well as from the last pump refill visit prior to explant to the prospective pain medication dose and pain scores using the valve-gated pump and collected at refill visits 1, 2 and 3 after valve-gated pump implant (but not exceed 12 months).

Sex: All

Ages: 22 to 85 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Be male or female between the ages of 22 and 85 years
2. Be capable of giving informed consent and completing assessments required by the study
3. Have pain intensity of greater than 5 out of 10 as measured by VAS
4. Have an active existing peristaltic intrathecal drug delivery system
5. Have stable drug dosage for at least 6 weeks prior to valve-gated pump implant
6. Be an appropriate candidate for surgery
7. Be able to comply with required study visits and assessments including English proficiency

Exclusion criteria

1. Have a significant pain disorder not intended to be treated with the test device or comparator
2. Be terminally ill and/or have a life expectancy of less than 6 months
3. Be a pregnant/lactating woman or a woman of child-bearing potential
4. Have a systemic or local infection (contraindicated for pump implantation)
5. Have history/evidence of an active disruptive psychiatric disorder or other known condition with potential to impact compliance with study visits and assessments
6. Have an underlying condition increasing susceptibility to infection

Prometra® Programmable Pump

Active Comparator group

Description:

Pain scores and drug doses will be prospectively collected for valve-gated Prometra® Programmable Pump system(Flowonix Medical)' at (refill #1, refill #2, refill #3) and will be compared to retrospectively collected pain (VAS) scores and drug doses from the last refill prior to peristaltic pump explant.

Treatment:

Device: Prometra II Programmable Pump system(Flowonix Medical)

Prior records for peristaltic pump

Other group

Description:

Prior pain scores and drug doses from the patients who need a new valve gated pump will be recorded and used for comparison after it is changed.
