Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The proposed study is a prospective, multi-center, two-arm, randomized, crossover design to be conducted at up to 10 sites. The study will enroll up to 100 subjects in order to include up to 10 subjects in the study per site. Subjects selected to participate in the trial have back and/or leg pain, have been evaluated as a candidate for SCS and have agreed to undergo a temporary SCS trial using the Algovita® system with percutaneous leads. Each subject will be followed during the trial period of approximately 7+/-2 days. The study will end when the last subject has completed the trial period and exited. The expected enrollment period for this study is approximately six months. After exit from the clinical study, subjects will continue to be followed by their physician per usual care. All device and procedure-related AEs will be collected and reported per the study protocol.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • be eligible for SCS therapy according to the Algovita® SCS system Indications for Use statement
  • be undergoing a SCS trial using Algovita® SCS system
  • sign a valid, Institutional Review Board (IRB)-approved informed consent form.
  • be 18 years of age or older when written informed consent is obtained

Exclusion Criteria:

  • be contraindicated for an Algovita® SCS system
  • have a cognitive impairment or exhibits any characteristic, that would limit the study candidate's ability to assess pain relief or complete study assessments
  • have a life expectancy of less than 2 years
  • be participating in another clinical study that would confound data analysis
  • have a coexisting pain condition that might confound pain ratings
  • have a significant psychiatric disorder

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Low Pulse Width (<500 μsec)
Spinal Cord Stimulation System will be programmed to pulse widths <500 μsec.
Device: Algovita Spinal Cord Stimulation System

Active Comparator: High Pulse Width (>1000 μsec)
Spinal Cord Stimulation System will be programmed to pulse widths >1000 μsec
Device: Algovita Spinal Cord Stimulation System
The Algovita™ SCS system is indicated as an aid in the management of chronic intractable pain of the trunk and/or limbs, including unilateral or bilateral pain associated with failed back surgery syndrome, intractable low back pain and leg pain.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Effect of Pulse Widths on Pain Clinical Outcomes
Time Frame: For 7 days following intervention
To evaluate the effect of conventional pulse widths <500 μsec and pulse widths >1000 μsec on clinical outcomes during temporary trial as measured by patient defined pain maps.
For 7 days following intervention

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Targeted Pain
Time Frame: For 7 days following intervention
To evaluate the effect of conventional pulse widths <500μsecand pulse widths and >1000μsecon clinical outcomes during temporary trial as measured by the number of participants that reported significant change in targeted pain compared to baseline using the NRS at the end of the trial period.
For 7 days following intervention
Distribution of Paesthesia
Time Frame: For 7 days following intervention
At end of each arm, subjects will be asked to complete a diagram that shows distribution of paresthesia.
For 7 days following intervention
Research Participant Program Preference
Time Frame: For 7 days following intervention
At the end of the trial period, subjects will be asked to select their favorite program.
For 7 days following intervention
Quality of Pain Relief
Time Frame: For 7 days following intervention
At the end of the trial period, subjects will be asked to rate the quality of the pain relief achieved during the trial (from either arm) using the following ordinal scale; Excellent, Very Good, Good, Fair or Poor
For 7 days following intervention
Research Participant Pain Relief Satisfaction
Time Frame: For 7 days following intervention
At the end of the trial period, subjects will be asked to rate their overall satisfaction with the pain relief achieved during the trial (from either arm) using the following ordinal scale; Very Satisfied, Satisfied, Neither Satisfied nor Unsatisfied, Unsatisfied or Very Unsatisfied
For 7 days following intervention
