12. Current or history of central nervous system cancer

13. Any malignancy (EXCEPTION: localized non-melanoma skin cancers) within 5 years before
the screening visit or currently receiving systemic chemotherapy, radiation therapy,
or a surgical stabilization procedure

14. Significant hepatic disease as indicated by clinical laboratory results for the
following: =3 times the upper limit of normal (ULN) for aspartate aminotransferase,
alanine aminotransferase, = 2.5 time ULN alkaline phosphatase, or =1.5 times ULN for
total bilirubin)

15. 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

virus

18. Significant psychological conditions; dementia, major depression, or altered mental
state that in the opinion of the Investigator will interfere with study participation

19. Current treatment with systemic antibiotics or antivirals (EXCEPTION: topical
treatments)

20. Current treatment with anticoagulants /antiplatelet medications except for low dose
aspirin or low dose aspirin-containing compounds. Participants, if medically feasible,
can interrupt anticoagulant therapy by following local medical practice protocol for
intrathecal injections for participants on anticoagulant, antiplatelet therapy.

safety of the participants, the participant's ability to communicate the study staff,
or the quality of the data

26. Presence of an implanted intrathecal infusion system or peripheral neurostimulator

27. Presence of a generalized pain disorder such as fibromyalgia or complex regional pain
syndrome that in the opinion of the PI may impact on evaluation of response to the
study drug

28. Diagnosis of peripheral neuropathy of the lower extremities which in the opinion of
the PI, might interfere with the participant's ability to assess the effect of the
study drug on the radicular signs and/or symptoms
