Safety and Efficacy With NOVOCART® Disc Plus (ADCT) for the Treatment of Degenerative Disc Disease in Lumbar Spine

• Status: Completed
• Trial end date: 2021-06-14
• Target enrollment: 0
• Participant gender: All

Summary

NOVOCART® Disc plus is being investigated to explore its clinical applicability, safety and efficacy in the repair of a herniated disc with an indication for an elective sequestrectomy, and of the adjacent degenerated disc, if present. The objective of this clinical study is to provide basis for a confirmatory study design (endpoints, methodologies) (Phase II), and to develop a safety profile (Phase I). This study further aims at developing and validating known and new biologic markers for the quality and clinical efficacy of the product as requested in the context of identity, purity and potency characteristics of the medicinal/investigational product.

• Phase: Phase 1/Phase 2
• Accepts Healthy Volunteers?: No

Criteria

Inclusion Criteria:

2. The patient has an indication for sequestrectomy according to the guidelines of DGNC and DGOOC

3. The patient is between 18-60 years of age.

4. The patient is physically and mentally able to participate in the study, and is able to understand the study, its goals and the possible risk factors involved. The patient is willing and able to participate in the follow-up visit plan at the study site and is able to understand and to complete study-relevant questionnaires in German language.

5. The patient is sufficiently informed about this trial orally and in writing. S/he had enough time for consideration, is willing to participate in the study and gives her/his written in-formed consent.

6. The patient confirms that s/he did not participate in a clinical study 90 days prior study inclusion. S/he agrees to refrain from participating in another clinical study during the NOVOCART® Disc Study and for another 90 days after study termination

Radiological Inclusion Criteria

Patients must meet all of the following criteria to be considered for enrollment in the NOVO-CART® Disc study.

1. The patient has a single-level lumbar disc herniation

2. The patient has more than 50% remaining disc height in the herniated disc in comparison to unaffected discs in the lumbar spine. If all discs show degenerative signs, disc height has to be at least 5 mm

3. The patient has no obvious signs of osteophytes and no end plate sclerosis in the lumbar segment to be treated with NOVOCART® Disc plus oder NOVOCART® Disc basic

Patients without adjacent degenerative disc (HD):

4. The adjacent proximal disc has no degenerative signs according to Pfirrmann Score stage 3 to 5.

Patients with adjacent degenerative disc (AAD):

4. The patients has additional degenerative signs in the proximal adjacent lumbar level ac-cording to Pfirrmann 3-4, but no more than 25% disc height reduction

Exclusion Criteria:

1. The patient has had a previous surgery at the lumbar level(s) and has been treated with NOVOCART® Disc plus oder NOVOCART® Disc basic.

2. The patient had a past recurrent disc herniation treated with sequestrectomy of the relevant disc.

3. The patient has any degenerative muscular or neurological condition that would interfere with evaluation of outcome measures including but not limited to Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, muscular dystrophy and myelopathic diseases of different causes.

4. BMI > 35 kg/m2

5. The patient has current or recent history of illicit drug, nicotine (more than 20 cigarettes per day) or alcohol abuse or dependence

6. CRP > 10mg/dl

7. The patient is pregnant, breastfeeding or actual planning to become pregnant. Female patients must be either at least two years postmenopausal or using one of the following means of birth control during the treatment phase, i.e. to transplantation

• surgical sterility

• double barrier methods, e.g. condom or diaphragm in combination with spermicide

• intrauterine contraceptive device

• bilateral vasectomy of sexual partner at least 90 days prior to enrolment in combination with barrier methods (e.g. condom or diaphragm)

• birth control pill

8. The patient has a history of known allergies or a suspicion of allergies to any of the NO-VOCART® Disc plus oder basic product components including hyaluronan, polyethylenglycol or albumin

9. Immune defects or the affinity for infections of known or unknown causes

10. The patient has a active systemic or local microbial infection, eczematization or inflammable skin alterations at the site of surgery (including Protozoonosis: Babesiosis, Trypanosomiasis (e.g. Chagas-Disease), Leishmaniasis, persistent bacterial infections, like Brucellosis, spotted and typhus fever, other Rickettsiosis, Leprosy, Recurrent Fever, Melioidosis or Tularaemia).

11. The patient is unable to undergo magnetic resonance imaging (MRI)

12. The patient has a history or a suspicion of a disease with chronically inflammable character, as rheumatoid arthritis, gout, pseudo-gout, metabolic bone diseases, Crohn's disease, ulcerative colitis, lupus erythematosus, or other autoimmune disorders

13. Known osteoporosis

14. The patient has a primary hyperparathyroidism or hyperthyroidism, has chronic renal failure or has had previous fragility fractures.

15. Systemic connective tissue or collagen disease

16. Hereditary ocular degenerations with unclear diagnosis, retinopathies based on connective tissue-defined causes, macular corneal dystrophy, (based on the fact that the human cornea expresses cartilage specific proteins as essential functional elements and thus may serve as an indicator for paralleling degenerative events in various cartilaginous tissues)

17. The patient has immune suppression

18. The patient has a history of blood coagulation disease of different genesis, including known haemorrhagic diathesis of unknown cause

19. The patient had undergone chemo or radiotherapy within the past 5 years, or had any cancer other than non-melanoma skin cancer treated with curative intent within the past 5 years

20. Known diabetes, drug treated

21. Ulterior concomitant diseases or functional impairments of specific organs, which exclude study participation by the assessment of the investigator

22. The patient is a prisoner
