Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Low back pain (LBP) is the leading cause of disability worldwide. Currently available treatment options for treating low back facet joint pain include acupuncture, pain medications, psychotherapy, anti-inflammatory steroid injections into the joints, exercise, physical therapy, rest, chiropractic treatments, surgery, and radiofrequency ablation (RFA). RFA uses radio waves to target and burn the nerves that send the pain signals to the participant's brain. The purpose of this study is to compare the standard treatment of RFA to a newer therapy called iovera°. The iovera° system is a newer procedure for nerve pain that freezes the targeted nerves leading to a temporary block of the nerve without causing any permanent damage to the nerve. With the nerve blocked, pain is immediately relieved. The nerve reconnects over time and goes back to working exactly as it did before the procedure. The investigators want to see if iovera° therapy is effective in treating people with facet joint-mediated chronic low back pain (CLBP).

If the participant decide to participate in the study, the investigators will ask the participant to undergo either an RFA or iovera° procedure to treat the participant's CLBP. After the procedure, the investigators will ask the participant to complete surveys to track the participant's response to the procedure at 15 time points over a 1-year period. These time points consist of phone calls and online surveys.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Potential subjects will be screened within 30 days prior to the iovera° treatment. After the Informed Consent Form (ICF) is signed, demographic information (including the Pain Catastrophizing Scale (PCS), Oswestry Disability index (ODI), and Patient Health Questionnaire (PHQ-9)), medical and surgical history, concomitant medications/concurrent procedures information, and vital signs will be collected. An assessment of the intended treatment areas will be conducted. Subjects will assess the pain in their low back region using a Numeric Rating Scale (NRS) and health-related quality of life (EQ-5D-5L) at the screening visit. When screening test results are received and the subject is deemed eligible for the study, the subject will be notified that he or she is enrolled in the study and will receive study procedure.

Study Procedures are Radiofrequency ablation (RFA) and the iovera° system. The site investigators will be trained to perform RFA and to use the iovera° device and a single unblinded research team member will administer the iovera° procedure. The procedure administering investigator(s) will not perform any of the study-specific assessments.

Post-treatment:

After the study procedure, subjects will be instructed to take their prescribed pain medications (i.e., opioid and non-opioid) as needed in response to their pain experience and record their pain score before taking their medication.

Subjects must be instructed to report any adverse device effects and adverse events (AEs) to the Investigator from the time the ICF is signed through Day 360 (±7 days). Safety will be assessed while subjects are in the facility. The total duration of study follow-up will 360 days (± 7 days). Adverse device effects, serious adverse device effects, adverse events, and serious adverse events will be recorded from the time the ICF is signed through Day 360 (± 7 days). Any concomitant medications used to treat AEs through postsurgical Day 360 (± 7 days) will also be recorded.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

iovera system

Uses liquid nitrous oxide contained within the device and a closed-end needle to create a precise zone of cold to denature the target medial branch nerve supplying the facet joint by Wallerian degeneration (second degree axonotmesis) preserving the epineurium, perineurium, and endoneurium.

Group Type ACTIVE_COMPARATOR

iovera system

Intervention Type DEVICE

Reusable, portable Handpiece, along with single patient use sterile Smart Tips (i.e., cryoprobes) and disposable nitrous oxide (N2O) cartridges. The iovera° system produces the desired effect through initiation of a cooling cycle. Each cooling cycle is initiated by fully inserting the Smart Tip into the selected procedure site and activating the cryogen flow. The Smart Tip needles are made of stainless steel and have a closed tip, fully enclosing the cryogen. The STT21180STIM Smart Tip will be used in this study.

Radiofrequency ablation

Utilizes radiofrequency energy to heat and denature the target medial branch nerve supplying the facet joint.

Group Type ACTIVE_COMPARATOR

Radiofrequency ablation alone

Intervention Type DEVICE

An electrode at the tip of the needle sends radio waves that lesion the nerve bundles.
