Secondary objectives: ● Evaluate degree of disability over time as measured by the Oswestry Disability Index (ODI). ● Characterize the change of the subject’s radiculopathy symptoms and overall condition using PainDETECT, Brief Pain Inventory – Short Form (BPI - SF), Clinical Global Impression of Change (CGIC), and Patient Global Impression of Change (PGIC). ● Evaluate the safety of single and repeat SP - 102 TF injections.

Trial – Sample Size Statistical Analysis Plan ● The sample size provides 90% power to detect a 1 - point difference in change from Baseline in the mean NPRS average daily leg pain score in the affected leg over 4 weeks between the 2 treatment groups. ● The sample size was calculated with a Student’s t - test at the 2 sided 0.05 significance level assuming a standard deviation (SD) of 2.8. ● In order to account for an expected 15% dropout rate, approximately 400 subjects overall will be enrolled in approximately 45 study sites in the US. If the dropout rate is higher than 15% then additional subjects will be enrolled to achieve a total of 332 completed subjects. The trial enrolled 401 subjects, yields 343 completers.

Contains 10 topics concerning intensity of pain, lifting, ability to care for oneself, ability to walk, ability to sit, sexual function, ability to stand, social life, sleep quality, and ability to travel. Each question scored 0 - 5, where 5 indicating most severe disability. All scores are summed, multiplied by 2 to obtain the Index (range 0 to 100).
