A Research Study to Characterize the Pharmacodynamics and Safety of Repeat Dose SP-102

Phase 2

Completed

Brief Summary: This is an open-label, single-arm, repeat dose study to characterize the pharmacodynamics and safety/tolerability of SP-102 administered by epidural injection.

Primary Outcome Measures

Name	Time	Method
Change in Plasma Cortisol Concentrations From Baseline	12 Weeks	Dexamethasone-induced hypothalamic-pituitary-adrenal (HPA) suppression is evaluated by monitoring SP-102 induced changes in plasma cortisol levels from Baseline. The T1 (index) and T2 (repeat) injections of SP-102 are separated by 4-8 weeks
Change in Blood Glucose Levels From Baseline	12 Weeks	Dexamethasone-induced hypothalamic-pituitary-adrenal (HPA) suppression is evaluated by monitoring SP-102 induced changes in blood glucose levels from Baseline. The T1 (index) and T2 (repeat) injections of SP-102 are separated by 4-8 weeks
Change in White Blood Cell (WBC) Levels From Baseline	12 Weeks	Dexamethasone-induced hypothalamic-pituitary-adrenal (HPA) suppression is evaluated by monitoring SP-102 induced changes in WBC levels from Baseline. The T1 (index) and T2 (repeat) injections of SP-102 are separated by 4-8 weeks

Secondary Outcome Measures

Name	Time	Method
Incidence of Treatment-Emergent Adverse Events (TEAEs)	12 weeks	Incidence of treatment-emergent AEs (TEAEs) related to study drug.
Change in Numeric Pain Rating Scale (NPRS) Scores for Leg Pain From Baseline	12 weeks	The NPRS is an 11-point scale (0- to 10-point scale where 0 is no pain and 10 is worst pain imaginable) that allows subjects to rate the severity of their pain intensity at various points in time (Turk et al., 2003). Subjects used the NPRS to record their current pain, average pain over 24 hours, and worst pain over 24 hours for both affected leg(s) and back pain. NPRS average leg pain scores over 24 hours are presented.
Change in Numeric Pain Rating Scale (NPRS) Scores for Back Pain From Baseline	12 weeks	The NPRS is an 11-point scale (0- to 10-point scale where 0 is no pain and 10 is worst pain imaginable) that allows subjects to rate the severity of their pain intensity at various points in time (Turk et al., 2003). Subjects used the NPRS to record their current pain, average pain over 24 hours, and worst pain over 24 hours for both affected leg(s) and back pain. NPRS average back pain scores over 24 hours are presented.
