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 Phase 1, safety and efficacy study of XT-150 in adult participants experiencing back pain due to inflammation of the facet joint osteoarthritis (FJOA) and who are eligible for intra-synovial glucocorticoid injection, or radiofrequency ablation of medial branches of the primary dorsal ramus of the exiting nerve root, which innervates the adjacent facet joints.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.
Interventional

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

14 years to 86 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Male or female, between 18 and 90 years of age, inclusive.
  2. Sufficiently severe facet arthropathy (OA) of lumbar facets as determined by imaging, eg. CT or MRI, to establish an underlying basis of disease, as determined by usual bony and ligamentous signs of OA.
  3. Complaint of nociceptive, mechanical pain of lumbar spine, in particular pain localized to paramedian axis as opposed to midline or radicular. Radicular pain as a secondary finding may be allowed if it is addition to mechanical pain and can be clinically distinguished by subject
  4. Low Back Pain (LBP) worsened by activity or motion of region
  5. Have had a positive diagnostic facet pain block with lignocaine; admittance if subject gains 50% relief of pain within 30 minutes of test injection
  6. Be free of local or intra-articular infection, tumor or other causes of localized LBP, for example Including spondylolysis/pars defect, and adjacent vertebral body compression fracture based on MRI evaluation.
  7. Symptomatic disease because of osteoarthritis, established by imaging of facet joint and defined as a worst pain of at least 40 at any time during the preceding week (based on scale of 0 to 100, with 100 representing "pain as bad as you can imagine") using Visual Analog Scale (VAS).
  8. Stable analgesic regimen during the 4 weeks prior to enrollment.
  9. Inadequate pain relief (minimum ≥50 mean on VAS with prior therapies lasting ≥3 months.
  10. In the judgment of the Investigator, acceptable general medical condition
  11. Male and female participants who are heterosexually active and not surgically sterile or post-menopausal must agree to use effective contraception, including abstinence, for the duration of the study and for 3 months after the study is completed
  12. Have suitable facet joint anatomy for intra-articular injection
  13. Willing and able to return for the follow-up (FU) visits
  14. Able to reliably provide pain assessment (FAST test score R2≥0.7)
  15. Able to read and understand study instructions, and willing and able to comply with all study procedures

Exclusion Criteria:

  1. Hypersensitivity, allergy, or significant reaction to any ingredient of the study drug, including double-stranded DNA, mannose, and sucrose
  2. Scheduled surgical procedure or nerve ablation to joint within the next 6 months; participant agrees not to schedule a surgical procedure, nerve ablation, or added facet injection within 6 months of study treatment
  3. High peri-operative risks which in the judgment of the investigator preclude a safe facet joint injection procedure (e.g. extreme obesity putting injection accuracy at risk, etc.)
  4. Current treatment with immunosuppressive (systemic corticosteroid therapy [equivalent to >10mg/day prednisone] or other strong immunosuppressant)
  5. History of immunosuppressive therapy; high-potency systemic steroids in the last 3 months.
  6. Currently receiving systemic chemotherapy or radiation therapy for malignancy
  7. Clinically significant hepatic disease as indicated by clinical laboratory results ≥3 times the upper limit of normal for any liver function test (e.g., aspartate aminotransferase, alanine aminotransferase, lactate dehydrogenase)
  8. Severe anemia (Grade 3; hemoglobin <8.0 g/dL, <4.9 mmol/L, <80 g/L; transfusion indicated), Grade 1 white cell counts (lymphocytes <LLN - 800/mm3; <LLN - 0.8 x 109 /L, neutrophils <LLN - 1500/mm3; <LLN - 1.5 x 109 /L)
  9. Positive serology with reflex for human immunodeficiency virus, hepatitis B virus, or hepatitis C virus within 4 weeks of commencing the study
  10. Significant neuropsychiatric conditions; dementia, major depression, or altered mental state that in the opinion of the Investigator will interfere with study participation
  11. Current treatment with systemic antibiotics or antivirals (EXCEPTION: topical treatments)
  12. Current treatment with anticoagulants, other than low-dose aspirin
  13. Known or suspected history of active alcohol or intravenous/oral drug abuse within 1 year before the screening visit
  14. Use of any investigational drug or device within 1 month before enrollment or current participation in a trial that included intervention with a drug or device; or currently participating in an investigational drug or device study.
  15. Any condition that, in the opinion of the Principal Investigator, could compromise the safety of the participant, the participant's ability to communicate with the study staff, or the quality of the data

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.

Time Frame: 6 months
0 - 100, 100 worst possible pain
6 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.
