Detailed Description
This is a phase IIb, prospective, multi-country, multicenter, randomized, double-blind, placebo-controlled, parallel group study to investigate the efficacy, safety and transformation of NP following single intradiscal injection of STA363 (lactic acid) into one or two IVDs compared to placebo for the treatment of discogenic low back pain. This study will be conducted in Russia, Spain and the Netherlands.
The primary objective is to demonstrate superiority of STA363 over placebo in reducing low back pain as measured by the NRS. A total of 168 patients will be screened in the study with the aim to recruit 126 patients to be randomly allocated to one of the three treatment groups:
Group 1 - 42 patients will receive STA363 containing 90 mg (60 mg/mL) lactic acid Group 2 - 42 patients will receive STA363 containing 180 mg (120 mg/mL) lactic acid Group 3 - 42 patients will receive placebo
The investigational medical product (IMP) will be injected into the center of up to two IVDs. Patients with two discs appropriate for treatment will be treated at both affected levels by two separate injections.
Each patient will have 5 visits to study site and 1 telephone call. The patient's total time in the study will be approximately 61 weeks (~15 months) including an 8-week screening period.
Each patient will perform a screening visit (Visit 1) maximum 60 days before planned treatment. Randomization and treatment will be performed at Visit 2 (Day 1) after confirmation of patient's eligibility for the study. The IMP will be administered, monitored by fluoroscopy or other available method of real-time x-ray imaging to ensure that an injection is correctly placed in the IVD nucleus and that no leakage occurs. Immediately after treatment the patients should remain supine for as long as possible (at least 1 hour). For safety reasons, patients will be allowed to leave the clinic not earlier than 2 hours after the last injection. After leaving the clinic, patients will be offered analgesics and/or other measures according to standard clinical practice. They will also be given advice on restricted physical activity during the first two weeks after injection. Patients should not drive or operate machinery for 12 hours following the treatment procedure.
Patients will be followed up at 1 month (Visit 3/Day 30±7, visit to study site), 3 months (Visit 4/Day 90±7, telephone call), 6 months (Visit 5/Day 180±7, visit to study site) and 12 months (Visit 6/Day 360±7, visit to study site) after treatment. Follow-up MRI will be conducted as part of Visit 5 and Visit 6, to assess the transformation of the NP into connective tissue and other disc characteristics.

Eligibility Criteria
Ages Eligible for Study
Accepts Healthy Volunteers
Description
Inclusion Criteria:
- Signed informed consent prior to any study related procedures.
- Male and female patients ≥18 and ≤70 years.
- Chronic discogenic low back pain present for more than 6 months prior to the screening visit.
- Insufficient response or lack of response to at least 6 months of non-operative treatment (analgesics and/or anti-inflammatory medications [paracetamol, non-steroidal anti-inflammatory agents (NSAIDs), opioids], physiotherapy, rehabilitation therapy etc.).
Patients who meet all the following NRS selection criteria:
- Presence of ≥5 pain NRS assessments (entries) for 7 consecutive days.
- NRS daily pain scores between 3-9.
- Not more than two ratings "3".
One or two treatable IVDs of Pfirrmann grade 2 to 3 on MRI at L2/3 to L5/S1 as confirmed by a central reader, AND the following criteria are met:
- Treatable IVD(s) must be IVD(s) with the highest Pfirrmann grade observed in the patient (e.g. a patient with one IVD of grade 3 and four IVDs of grade 2 is considered eligible only if IVD of grade 3 will be injected).
- Patients with treatable IVD(s) of grade 2 must have all other lumbar discs rated as grade 1.
- Not more than two IVDs of grade 3 at any lumbar level.
- No IVDs of grade 4 or 5 at any lumbar level.
- Ability to understand the written and verbal information about the study.
Exclusion Criteria:
- Treatment with any investigational product within 3 months prior to the screening visit.
- Patients with more than two painful IVDs.
- A painful IVD above L2/3 level.
- Current infection or prior history of spinal infection (e.g., discitis, septic arthritis, epidural abscess) or an active systemic infection.
- Previous lumbar spine surgery.
- Previous disc invasive treatment procedures at the affected level(s) (e.g., intradiscal electrothermal therapy, intradiscal radiofrequency thermocoagulation).
- Evidence of prior lumbar vertebral body fracture or trauma.
- Need for spinal decompression assessed by the Investigator.
- Presence of IVD extrusion or sequestration, or other radiologic findings that in the opinion of the investigator disqualify the patient from being included.
- Spondylolisthesis or retrolisthesis Grade 2 and above or spondylolysis at the index or adjacent level(s).
- Lumbar spondylitis or other undifferentiated spondyloarthropathy affecting the index IVD.
- Patients previously included in the study.

- Severe intercurrent illness (e.g. rheumatic disease or chronic pain syndrome) or concomitant treatment (e.g. immunosuppressive drugs), which, in the opinion of the Investigator, may put the patient at risk when participating in the study, or affect the patient's ability to take part in the study.
