Brief Summary:
This clinical trial evaluate the safety, tolerability and exploratory efficacy of targeted single injection of AMG0103 in subject with chronic discogenic lumbar back pain

Condition or disease Intervention/treatment Phase
Degenerative Disc Disease Drug: Placebo Drug: AMG0103 Phase 1

Detailed Description:

This is a Phase 1b, multicenter, double-blind, single ascending dose study designed to evaluate the safety of AMG0103 in adult male and female subjects with chronic discogenic lumbar back pain.

This protocol anticipates that 8 subjects with symptomatic single level discogenic pain will be enrolled in each of up to 3 dose-escalation cohorts. Subjects in each cohort will receive AMG0103 or Placebo as a targeted, single, intradiscal injection.

Ages Eligible for Study:   18 Years to 75 Years   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Male or female, between 18 and 75 years of age, inclusive, and skeletally mature, in the opinion of the investigator.
  2. Has provided written informed consent before undergoing any study-specific procedures.
  3. Has chronic low back pain for at least 6 months, where back pain is greater than leg pain.
  4. Has separate low back pain and leg pain VAS scores within the following parameters:

    1. Average low back pain VAS score of at least 40 mm and less than 90 mm on a 100 mm visual analog scale.
    2. Average leg pain VAS score that is less than or equal to 50% of the average low back pain VAS score above, where leg pain VAS scores are measured on a 100 mm visual analog scale.
  5. Has had inadequate response to conservative medical care over a period of at least 3 months.
  6. Diagnosis of painful degenerative disc disease at one lumbar level from L1 to S1 confirmed by subject history and radiographic studies (eg, MRI, x-rays). Radiographic studies must demonstrate the following:

    1. A Pfirrmann score of 3 or 4 on MRI in just a single disc between L1 and S1
    2. With or without contained disc herniations of <3 mm protrusion with no radiographic evidence of neurologic compression
    3. Disc height loss of the symptomatic disc is less than 50% of the adjacent discs
    4. All discs other than the index disc must have a Pfirrman score of less than 3
    5. No spondylolisthesis or instability on flexion/extension views of more than 1-2 mm
    6. No evidence of sacroiliac, or extra-spinal, pathology that could account for lumbar back pain
    7. No more fluid in, or widening of, the facet joints around the symptomatic disc than is seen on the other facet joints of "normal" levels
  7. Has a Body Mass Index (BMI) between 15.0 and 35.0 kg/m2 at the screening visit.
  8. Oswestry Disability Index score of at least 30 and not more than 90 on the 100 point questionnaire.

  15. Has had any lumbar intradiscal injection procedure (eg, injection of corticosteroids, methylene blue, dextrose, or glucosamine and chondroitin sulfate). Discography may be performed, but must be done at least 3 weeks (or more) prior to the injection procedure in this study.
  16. Has had any epidural steroid injection(s) within 3 months prior to study treatment.

  26. Is transient or has been treated in the 6 months prior to providing informed consent for alcohol and/or drug abuse in an inpatient substance abuse program.
  27. Is currently incarcerated (a prisoner).
  28. Is an Investigator-site employee or immediate family (defined as a spouse, parent, child, or sibling, whether biological or legally adopted) of an Investigator-site employee.
  29. Is a Sponsor employee (permanent, temporary contract worker, or designee responsible for the conduct of the study) or immediate family (defined as a spouse, parent, child, or sibling, whether biological or legally adopted) of a Sponsor employee.
