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

This is a prospective, open-label, single-arm study of patients diagnosed with vertebrogenic low back pain for a minimum of 6 months with conservative care. Participants will receive the Intracept System procedure to ablate the basivertebral nerve within the vertebral body. Treatment is performed on all vertebral bodies with Modic type 1 or type 2 changes on MRI from L3-S1.

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.

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
Oswestry Disability Index (ODI) - 3 Months
Time Frame: 3 months
Change in mean Oswestry Disability Index (ODI) total score from baseline to 3 months post-treatment. ODI total score scale of 0 (no disability) to 100 (complete disability), with categories of 0-20 (minimal disability), 21-40 (moderate disability), 41-60 (severe disability), 61-80 (crippling back pain), and 81-100 (bed-bound or exaggerating). The minimally clinically important difference in ODI from baseline is considered to be a 10 points reduction from baseline.
3 months

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
Visual Analog Scale (VAS) - 3 Months
Time Frame: 3 Months
Change in the mean visual analog scale (VAS) low back pain from baseline to 3 months post treatment. VAS is a 10 point numeric scale with 0 being no pain and 10 being worst imaginable pain. The minimal clinically important difference is a 2 point reduction from baseline.
3 Months
ODI Responder Rate - 3-Month
Time Frame: 3 Months
Number & percent of patients with greater than or equal to 15 point reduction in Oswestry Disability Index (ODI) from baseline to 3 months post treatment. ODI is scored on a scale of 0 (no disability) to 100 (complete disability), with categories of 0-20 (minimal disability), 21-40 (moderate disability), 41-60 (severe disability), 61-80 (crippling back pain), and 81-100 (bed-bound or exaggerating). The minimally clinically important difference for this tool is considered to be 10 points.
3 Months
VAS Responder Rate - 3 Month
Time Frame: 3 Months
Number and percentage of participants with a greater than or equal to 2 point reduction from baseline in visual analog scale (VAS) for low back pain at 3 months post treatment. VAS is a patient-reported 10 point numeric pain scale with 0 being no pain and 10 being worst imaginable pain. The minimal clinically important difference in VAS from baseline is a 2 point reduction.
3 Months
ODI -12 Months
Time Frame: 12 Months
Change in mean Oswestry Disability Index (ODI) total score from baseline to 12 months post treatment. ODI total score is on a scale of 0 (no disability) to 100 (complete disability), with categories of 0-20 (minimal disability), 21-40 (moderate disability), 41-60 (severe disability), 61-80 (crippling back pain), and 81-100 (bed-bound or exaggerating). The minimally clinically important difference for this tool is considered to be 10 point reduction in ODI.

VAS - 12 Month
Time Frame: 12 Months
Change in mean visual analog scale (VAS) for low back pain score from baseline at 12 months. VAS is a patient-reported 10 point numeric pain scale with 0 being no pain and 10 being worst imaginable pain. The minimal clinically important difference in VAS from baseline is a 2 point reduction.
12 Months
ODI Responder Rate - 12-Month
Time Frame: 12 Months
Number and percent of patients with greater than or equal to 15 point reduction in Oswestry Disability Index (ODI) total score from baseline to 12 months post treatment. ODI total score scale of 0 (no disability) to 100 (complete disability), with categories of 0-20 (minimal disability), 21-40 (moderate disability), 41-60 (severe disability), 61-80 (crippling back pain), and 81-100 (bed-bound or exaggerating). The minimally clinically important difference for this tool is considered to be 10 points.
12 Months
VAS Responder Rate - 12 Months
Time Frame: 12 Months
Number and percent of participants with a reduction of greater than or equal to 2 points of the visual analog scale (VAS) at 12 months post treatment. VAS is a patient-reported 10 point numeric pain scale with 0 being no pain and 10 being worst imaginable pain.
