• Status: Completed
• Trial end date: 2019-08-29
• Target enrollment: 0
• Participant gender: All

Summary

A phase I, randomized, double-blinded, placebo-controlled, single ascending dose study to investigate the safety, local tolerability and transformation of nucleus pulposus following intradiscal injection of STA363 or placebo in patients with discogenic low back pain.

15 patients will participate in either of 3 dose groups, each comprising 5 patients:

• Group 1: STA363 dose 1 (3 patients) or placebo (2 patients)

• Group 2: STA363 dose 2 (3 patients) or placebo (2 patients)

Exclusion Criteria:

• Treatment with any investigational product within 3 months prior to the screening visit

• More than one painful intervertebral disc

• A painful intervertebral disc above L3/4 level

• Current infection or prior history of spinal infection (e.g., discitis, septic arthritis, epidural abscess) or an active systemic infection
