Detailed Description
This study is a double-blinded, randomized, placebo-controlled, dose escalation Phase 1/2a study. The objective is to determine the safety, tolerability, and efficacy of CELZ-201-DDT administered as an intramuscular injection for the treatment of lower back pain in patients with Degenerative Disc Disease. Subjects who meet all criteria for inclusion will be enrolled and randomized into either low, medium or high dose of CELZ-201-DDT versus Placebo, with a total of 30 subjects enrolled. Each dosing cohort will contain ten subjects (n=10), with eight subjects (n=8) receiving the investigational product and two subjects (n=2) randomized to receive placebo. Each subject will receive six paraspinal intramuscular injections (three injections per side) of either CELZ-201-DDT or placebo into the lumbar musculature under direct ultrasound guidance.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Low Dose Subjects in the low dose arm will receive a single administration of either 6x10^6 cells (n=8) or a placebo injection (n=2). Each subject will receive six paraspinal intramuscular injections (three injections per side) of either CELZ-201-DDT or placebo into the lumbar musculature under direct ultrasound guidance. |
Drug: CELZ-201-DDT
Subjects enrolled in the trial will receive CELZ-201-DDT at the specified dose into the lumbar paraspinal musculature. Each subject will receive a total of six injections, three injections on each side, under direct ultrasound guidance.
Other: Placebo
Subjects will receive a placbeo injection into the lumbar paraspinal musculature. Each subject will receive a total of six injections, three injections on each side, under direct ultrasound guidance.
|
| Experimental: Medium Dose Subjects in the medium dose arm will receive a single administration of either 12x10^6 cells (n=8) or a placebo injection (n=2). Each subject will receive six paraspinal intramuscular injections (three injections per side) of either CELZ-201-DDT or placebo into the lumbar musculature under direct ultrasound guidance. |
Drug: CELZ-201-DDT
Subjects enrolled in the trial will receive CELZ-201-DDT at the specified dose into the lumbar paraspinal musculature. Each subject will receive a total of six injections, three injections on each side, under direct ultrasound guidance.
Other: Placebo
Subjects will receive a placbeo injection into the lumbar paraspinal musculature. Each subject will receive a total of six injections, three injections on each side, under direct ultrasound guidance.
|
| Experimental: High Dose Subjects in the high dose arm will receive a single administration of either 24x10^6 cells (n=8) or a placebo injection (n=2). Each subject will receive six paraspinal intramuscular injections (three injections per side) of either CELZ-201-DDT or placebo into the lumbar musculature under direct ultrasound guidance. |
Drug: CELZ-201-DDT
Subjects enrolled in the trial will receive CELZ-201-DDT at the specified dose into the lumbar paraspinal musculature. Each subject will receive a total of six injections, three injections on each side, under direct ultrasound guidance.
Other: Placebo
Subjects will receive a placbeo injection into the lumbar paraspinal musculature. Each subject will receive a total of six injections, three injections on each side, under direct ultrasound guidance.

Outcome Measures
Primary Outcome Measures
- Evaluate safety of CELZ-201-DDT administered as intramuscular injections in subjects experiencing chronic lower back pain at a low, medium, or high dose. [6 months]
The primary outcome will be evaluated by the incidence of grade 3 or 4 or serious adverse events in all dosing cohorts at 6 months.
Secondary Outcome Measures
- Evaluate the potential efficacy of CELZ-201-DDT therapy in terms of pain alleviation and improved mobility in subjects experiencing chronic low back pain. [12 months]
The secondary outcome will be evaluated by change in pain as judged by the Visual Analogue Score (VAS), using a score of 0-10.
- Evaluate the potential efficacy of CELZ-201-DDT therapy in terms of pain alleviation and improved mobility in subjects experiencing chronic low back pain. [12 months]
The secondary outcome will be evaluated by change in disability as judged by the Oswestry Disability Index (ODI) for back pain.
- Evaluate the potential efficacy of CELZ-201-DDT therapy in terms of pain alleviation and improved mobility in subjects experiencing chronic low back pain. [12 months]
The secondary outcome will be evaluated by change in requirements for pain medications to manage back pain.
Eligibility Criteria
