简要总结
This is a prospective, randomized, controlled, multi-center clinical study. Approximately 208 subjects will be enrolled at approximately 12-15 active duty military, veterans' care, and civilian sites. Eligible subjects will be randomized in 1:1 ratio to receive either Sacroiliac denervation using CRF (treatment group) or standard medical management ("SMM," control group).
详细描述
This study will be a 12-month prospective, randomized, controlled, prospective, open-label, multi-center clinical study. Adult subjects over the age of 21 with diagnosed chronic intractable sacroiliac joint pain (≥ 3 months), who have been previously unresponsive to conservative therapy and who meet the selection criteria are eligible to participate in this study. Approximately 208 subjects will be enrolled at up to 15 sites in a 1:1 randomization ratio to receive either denervation using the SInergy System (cooled radiofrequency (CRF), treatment group) or standard medical management (SMM, control group). Follow-up will be conducted for a total of 12 months post-Coolief (cooled radiofrequency ablation) procedure, with the primary endpoint being completed at month 3. The control arm will utilize physician prescribed standard medical management (SMM). For this protocol, this includes, but is not limited to, medications, physical therapy, lifestyle changes, acupuncture, yoga, chiropractic, and therapeutic injections. An optional crossover-to-treatment design was adopted for subjects randomized to standard medical management after their 3-month visit, because it would be considered unethical to withhold treatment that could potentially offer pain relief to those subjects undergoing standard medical management who continue to suffer from pain.
Eligibility includes BOTH of the following:
-
50% pain relief lasting for the expected duration of anesthetic or medication from a therapeutic or diagnostic sacroiliac joint injection; AND
-
50% pain relief lasting for the expected duration of anesthetic from a standardized set of lateral branch blocks, with total volume of no more than 1 milliliter (ml) of 0.5% Bupivacaine, Ropivacaine (or similar). Ideally, 0.5 ml will be utilized at L5 and the remaining 0.5 ml should be divided in at least two locations along the foramen line
After the CRF treatment, the CRF treatment group subjects will visit the blinded assessor for follow up at 1, 3, 6, 9, and 12 months. At the month 3 visit (three months post-randomization), subjects initially randomized to the conservative therapy group will be assessed to determine eligibility to receive CRF treatment.

盲法说明
The study is an assessor blinded trial and deliberate action will be needed to ensure the blind remains. This begins with randomization procedures and carries through the follow up visits. It is suggested that all follow up visit documentation not contain the visit number, but instead utilize visit dates to track progress.

- •Sacroiliac joint (SIJ) pain that is refractory to standard of care treatments such as non-steroidal anti-inflammatory drugs (NSAIDS), physical therapy, etc.
- •At least one positive SIJ pain provocation test (Distraction, Gaenslen's, FABER, Sacral Sulcus tenderness, thigh thrust, compression or sacral thrust).
- •Back pain is predominantly below the lumbar (L) 5 vertebrae.
- •Chronic low back pain lasting for longer than three months.
- •Greater than 50% pain relief lasting for the expected duration of anesthetic or medication from a therapeutic or diagnostic SIJ injection.

结局指标
主要结局
Change in average daily pain Numeric Rating Scale (NRS) score
时间窗: Baseline and 3 months
Numeric Rating Scale (NRS) - score range = 0 - 10. "0" corresponds to "no pain" and "10" indicates "worst pain imaginable". The means of these scores and their respective standard deviations are reported for each study group.
次要结局
- Mean change in score of Short Form 36-Physical Functioning (SF36-PF)(Baseline and 3 months)
- The proportion of subjects with at least a 2 points decrease or 30% drop in average daily pain related NRS score AND a rating of at least 5 on the Patient Global Impression of Change (PGIC)(Baseline and 3 months)
- Mean change in score of Patient Global Impression of Change (PGIC)(Baseline and 3 months)
- Mean change in score of Oswestry Disability Index (ODI)(Baseline and 3 months)
