A Prospective, Open Label, Pilot Study of Patient OutcoMes Following Successful TriAl of High Frequency SpInal CorD Stimulation at 10kHz (HF10™) Leading to Permanent Implant Compared to Trial Failure and Standard CarE for the TreatmeNt of Persistent Low BACK Pain of Neuropathic Origin (Maiden Back)

Rospective, Open Label, Pilot Study of Patient OutcoMes Following Successful TriAl of High Frequency SpInal CorD Stimulation at 10kHz (HF10™) Leading to Permanent Implant Compared to Trial Failure and Standard CarE for the TreatmeNt of Persistent Low BACK Pain of Neuropathic Origin

25 participants with back pain and no previous spinal surgery will be enrolled from a single NHS site in England.

Participants will have already discussed spinal cord stimulation (SCS) pain management with their consultant before being invited to participate. Participants will attend for 10 visits over a period of 66 months. At visit one, study suitability screening and informed consent will be conducted. Suitable participants will be booked to have SCS trial leads implanted and an external programmable High Frequency battery trial box as a day case (Visit 2). Participants will be contacted over the next 21 days to assess how the trial is progressing and to book a follow up appointment in clinic to remove the trial leads (Visit 3) where a treatment decision will be made. If a participant is determined as having had a successful trial they will be listed and implanted with a full HF10 SCS implant (Visit 4). The participants who proceed to a full HF10 SCS implant will be reviewed in the Clinic at 6, 12, 24, 36, 48 and 60 months post procedure. Their participation in this study will be no longer than 66 months. A successful trial is defined as a reduction in pain by 30% on a Visual Analogue Scale. Participants who do not obtain 30% reduction in 21 days is classed as a failed trial and once the leads are removed will be reviewed in clinic by the investigator for an alternative treatment plan (Visit 4). If a participant is determined a failed trial of HF10, they will remain in the study with their consent for the full follow up schedule. The follow-up for the failed trial cohort can be conducted via telephone to reduce the burden on this trial group.

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.

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 to 100 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All
