About this study
Official title: A Randomized, Double-Blind, Placebo-Controlled Proof of Concept Study to Assess the Safety and Efficacy of Elezanumab in Acute Traumatic Cervical Spinal Cord Injury
Acute Spinal Cord Injury (SCI) is a rare injury that leads to permanent neuromotor impairment and sudden disability. Approximately 25,000 people experience cervical SCI in the United States, Europe, and Japan every year. The purpose of this study is to see if elezanumab is safe and assess change in Upper Extremity Motor Score (UEMS) in participants with acute traumatic cervical SCI.
Elezanumab is an investigational drug being developed for the treatment of SCI. Elezanumab is a monoclonal antibody, that binds to an inhibitor of neuronal regeneration and neutralizes the inhibitor, thus potentially promoting neuroregeneration. This study is "double-blinded", which means that neither trial participants nor the study doctors will know who will be given which study drug. Study doctors put the participants in 1 of 2 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 3 chance that participants will be assigned to placebo. Participants 18-75 years of age with a SCI will be enrolled. Approximately 54 participants will be enrolled in the study in approximately 49 sites worldwide.
Read more
Participants will receive intravenous (IV) doses of elezanumab or placebo within 24 hours of injury and every 4 weeks thereafter through Week 48 for a total of 13 doses.
There may be a higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the course of the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

What is being measured
The primary outcome is the main question the study is designed to answer.
Upper Extremity Motor Score (UEMS)
The UEMS is a subscore of the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) that grades function of 5 key muscles in the upper limbs on a scale of 0 to 5 on each side from total paralysis to active full range of movement, respectively.
Measured: 52 Weeks
Number of Participants Experiencing Adverse Events
An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment.
Measured: Up to approximately 91 Weeks
Secondary outcomes (2)
Change from Baseline in Spinal Cord Independence Measures (SCIM III) Self-Care Score
The SCIM III self-care score addresses four areas of self-care management: feeding, grooming, bathing, and dressing. It has a total of 4 questions. Scores range from 0-20 where a score of 0 defines total dependence and 20 is indicative of complete independence.
Measured: Week 0 through Week 52
Change in Upper Extremity Motor Score (UEMS) From Baseline
The UEMS is a subscore of the International Standards for Neurological Classification of Spinal Cord Injury (ISNCSCI) that grades function of 5 key muscles in the upper limbs on a scale of 0 to 5 on each side from total paralysis to active full range of movement, respectively.
Measured: Week 0 through Week 52

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Elezanumab in people with Spinal Cord Injury (SCI), run by AbbVie at 41 sites in 7 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 11 Feb 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 41 sites in United States, Spain, Canada, Japan, South Korea and 2 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Upper Extremity Motor Score (UEMS) (time frame: 52 Weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Feb 2026.
