Eligibility
Key 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
Minimum age
18 Years
Maximum age
90 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key 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
