INTRACEPT: Prospective, Randomized, Multi-center Study Intraosseous Basivertebral Nerve Ablation for Treatment of CLBP (CLBP)

March 12, 2024 updated by: Relievant Medsystems, Inc.

INTRACEPT: A Prospective, Randomized, Multi-Center Study of Intraosseous Basivertebral Nerve Ablation for the Treatment of Chronic Low Back Pain

Prospective, open-label, 1:1 randomized controlled trial of Basivertebral nerve (BVN) Ablation arm vs Standard Care Control for the treatment of vertebrogenic chronic low back pain (CLBP). Participants in the the BVN Ablation arm will receive radiofrequency ablation of the BVN using the Intracept procedure for treatment of up to 4 vertebral bodies (L3 to S1). Participants in the Standard Care Control arm will continue on non-surgical standard care and will be offered optional crossover after 12 months of follow-up with follow-up of 6 months post crossover treatment.

The study had a pre-specified Interim Analysis with stopping rules for superiority when approximately 60% of the randomized participants have completed their 3-month primary endpoint study visit. An independent Data Safety Management Board (DSMB) reviewed the interim analysis results and recommended stopping enrollments for superiority and offering early crossover to the control arm participants.

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

Participants in the BVN Ablation arm will be followed for 24 months following treatment. BVN Ablation arm participants will be approached to participate in a sub study of 3 additional years of follow-up at their 24 month visit (total of 5 years of follow-up).

Control arm subjects who were originally to be offered optional crossover treatment after the 12 month follow-up visit were offered crossover per the DSMB recommendation at a mean of 176.5 days.

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

25 years to 70 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Inclusion Criteria:

  • Skeletally mature subjects at least 25 years of age
  • Chronic lower back pain for at least 6 months
  • Failure to respond to at least 6 months of non-operative conservative management

Exclusion Criteria:

  • Current or history of spinal infection
  • Modic changes at vertebral bodies other than L3 to S1
  • Contraindication to MRI

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
Difference Between Arms in Least Squared (LS) Mean Change in Oswestry Disability Index (ODI)
Time Frame: 3 months

Difference between arms in LS Mean change in ODI (baseline to 3 months post-treatment). ODI is measured 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 a 10 point reduction in ODI from a baseline in a patient.

These data are for interim analysis of the primary endpoint. Data for later time points will be included in the current Outcome Measures as additional Rows, once available.
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
Difference Between Arms in LS Mean Change in Visual Analog Scale (VAS)
Time Frame: 3 months post treatment / randomization

Difference between arms in LS Mean reduction in Visual Analog Scale (VAS) for low back pain from baseline to 3 months post treatment. VAS is a 10 point scale with 0 being no pain and 10 being worst imaginable pain. Participants are asked to indicate an x on the scale that corresponds to their perceived level of pain in their low back. The published minimal clinically important change in VAS is 2 points from baseline.

These data are for interim analysis of the primary endpoint. Data for later time points will be included in the current Outcome Measures as additional Rows, once available.
