Corticosteroid Lumbar Epidural Analgesia for Radicular Pain 2

This is a research study of SP-102, an experimental medication designed to relieve pain in patients with moderate to severe sciatica (pain in the lower back, hips, buttocks and legs). SP-102, placebo (a medication that looks like SP-102 but does not contain any active ingredient), or an active comparator (dexamethasone sodium phosphate) is given once by the participant's healthcare professional. If a participant meets qualifications, each participant will have the option of receiving one supplemental open-label injection of SP-102, greater than four weeks and up to twenty weeks after their first injection. The purpose of the study is to measure how well a single injection of the experimental medication, SP-102, relieves pain versus placebo. The study will also measure how well SP-102 relieves pain versus an active comparator medication (dexamethasone sodium phosphate). The study will also investigate the side effects of SP-102.

Determination of Sensitivity and Specificity of Straight Leg Raise Test Via Transforaminal Nerve Root Block

This study aims to evaluate the diagnostic accuracy of the straight leg raise test in patients with suspected lumbosacral radicular pain. Lumbosacral radicular pain is often caused by lumbar disc herniation and may radiate from the lower back or buttock to the leg. Although the straight leg raise test is commonly used in clinical practice, its diagnostic performance has been reported to vary. In this study, diagnostic transforaminal epidural steroid injection or selective nerve root block will be used as the reference standard. The sensitivity, specificity, likelihood ratios, and area under the curve of the straight leg raise test will be calculated. The findings may help guide clinicians in determining when the straight leg raise test is sufficient and when further diagnostic confirmation may be needed.

Study to Evaluate Safety of C-1101 Versus Sterile Saline in Adults With Chronic Painful Lumbosacral Radiculopathy

The purpose of this study is to evaluate the safety and tolerability of C-1101 administered as a single dose, transforaminal epidural injection compared to sterile saline
