NCT06611397

Brief Summary

This study will be a double-blinded, two-arm, prospective, randomized controlled pilot feasibility study in 40 evaluable subjects (20 in each arm) at one study site within the United States. Subjects in Arm 1 will receive unilateral Discogen treatment; subjects in Arm 2 will receive unilateral sham treatment (control). Treatment in both arms can include medications, e.g. NSAIDs or muscle relaxants for axial or radicular pain.

Outcome Measures

Primary Outcomes (2)

  • Primary Effectiveness

    Percent change from baseline for Numerical Pain Scale (NPS) radicular leg pain at 30 and 60 days. The NPS is a patient-reported assessment of pain intensity, ranging from 0 (No pain) to 10 (Severe pain).

    30 and 60 days.

  • Primary Safety

    Collection of all adverse events, including any device or procedure-related adverse events.

    60 days

Secondary Outcomes (2)

  • Change from baseline in Oswestry Disability Index

    30 and 60 days.

  • Numerical Pain Scale (NPS)

    30 and 60 days.

Study Arms (2)

Treatment Group

EXPERIMENTAL

Study subjects in the treatment group (Arm 1) will receive 3 daily Discogen treatments unilaterally within a one week (M-M) period, each lasting 25 minutes.

Device: Discogen Low pulsed ultrasound treatment

Sham Control Group

SHAM COMPARATOR

Subjects in the sham control arm (Arm 2) will receive 3 daily non-powered treatments unilaterally within a one week (M-M) period, each lasting 25 minutes

Device: Discogen Sham Treatment

Interventions

The ultrasound signal will be delivered unilaterally for 25 minutes, using a timer visible to the patient. The power generator will not be turned on for the sham treatment, but the wave generator will be displayed. All study subjects will receive a total of three daily Discogen treatments over the span of a single M-M work week

Sham Control Group

The device is a customized Low Intensity Pulsed Ultrasound (LIPUS) transducer system and power source. The transducer is biocompatible for skin contact. The system is capable of calibration to desired treatment parameters. The study subject will be placed in the prone position with all appropriate pressure points padded on the exam table. For the first treatment, fluoroscopic imaging (and/or ultrasonic guidance) will be used to guide the placement of the transducer over the anatomic target, unilateral at the L3-4, L4-5 or L5-S1 levels. The skin of the study subject's back will be marked with non-washable marking pen to indicate the site for placing the transducer during the first treatment. The subsequent treatment (second and third) can be done without using ultrasound guidance. The transducer will be placed on the marked site during the second and third treatment. The ultrasound signal will be delivered unilaterally for 25 minutes, using a timer visible to the patient. The power ge
