CLBP Single-Arm Long-Term Follow-up Study

April 23, 2025 updated by: Boston Scientific Corporation

A Prospective, Open-Label, Single-Arm Study of Intraosseous Basivertebral Nerve Ablation for the Treatment of Chronic Low Back Pain Long-term Follow Up

This is a prospective, noninterventional, observational post market data collection of long-term effectiveness and satisfaction outcomes for "A Prospective, Open-Label, Single-Arm Study of Intraosseous Basivertebral Nerve Ablation for the Treatment of Chronic Low Back Pain (CLBP Single-Arm Study)" population at three (3), four (4), and five (5) years post Intracept Procedure. The working hypothesis is that data collected in this study will demonstrate safety, efficacy, durability and reproducibility of BVN ablation treatment outcomes out to 3, 4, and 5-years post-procedure.

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

Patients were originally enrolled under NCT03266107 and followed through 12-months post Intracept Procedure. This study approached patients from NCT03266107 to collect additional long-term effectiveness and satisfaction outcomes at three (3), four (4), and five (5) years post Intracept Procedure.

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
Mean Change in ODI From Baseline to 5 Years Post Intracept Procedure
Time Frame: Difference between baseline and 5-year post treatment measurements. Patients originally enrolled under NCT03266107. Baseline information for this analysis is from NCT03266107. 5-years post Intracept Procedure data collected through this NCT record/study.
The Oswestry Disability Index (ODI) is a validated questionnaire of pain-related disability with total score on a scale of 0 (no disability) to 100 (complete disability). Categories for ODI total score are 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 published minimally clinically important difference for change in ODI is 10 points.
Difference between baseline and 5-year post treatment measurements. Patients originally enrolled under NCT03266107. Baseline information for this analysis is from NCT03266107. 5-years post Intracept Procedure data collected through this NCT record/study.

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.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment.
