Spinal injection antibody tested for movement recovery after neck injury
NCT ID NCT07840196
First seen Sep 24, 2026 · Last updated Sep 25, 2026 · Updated 1 time
Summary
Researchers are testing an experimental antibody called NG004 in adults who have a recent, incomplete cervical spinal cord injury from trauma. Participants receive repeated injections of NG004 or a placebo into the fluid around the spinal cord within 30 days of injury. The trial measures safety and side effects, how the body processes the antibody, and whether it improves arm and hand movement or daily functioning compared with placebo.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- NG004, an experimental human monoclonal antibody given by repeated injections into the spinal fluid
- What this could lead to
- If NG004 proves safe and shows signs of helping movement, it could become a new treatment option for people with recent incomplete cervical spinal cord injuries.
- What could go wrong
- This is an early Phase 1 trial with 120 participants, so its main goal is safety, not proof of benefit. The antibody may cause side effects, and any improvements in movement could turn out to be small or not clearly better than placebo.

Inclusion Criteria: * Acute incomplete cervical SCI (Neurological level of injury C1 ≤ lesion ≤ C8) with confirmed classification of American Spinal Injury Association (ASIA) impairment scale (AIS) B, C and D at Screening * 4-28 days post-injury and no earlier than 4 days after spinal surgery * No required mechanical ventilation or patients that do not completely depend on mechanical ventilation * Hemodynamically and clinical stable patient according to the acute SCI condition at baseline Exclusion Criteria: * Trauma caused by ballistic or other injury that directly penetrates the spinal cord including gunshot and knife wounds * Multiple levels of clinically relevant spinal cord lesions * Major brachial or lumbar plexus damage/trauma * Significant head trauma or other injury that was, in the opinion of the investigator, sufficient to interfere with the assessment of the spinal cord function * Other significant pre-existing or current severe systemic disease * History of or an episode of multiple sclerosis or Guillain-Barre syndrome * History of recent meningitis or meningoencephalitis * History of refractory epilepsy * Patients with uncontrolled bleeding diathesis and/or who require concomitant therapeutic anticoagulation and not related to SCI * Presence of any unstable medical or psychiatric condition * Drug dependence any time within the last 6 months before Screening * Pregnant or nursing women * History of a life-threatening allergic or immune-mediated reaction * Presence of infection around the location where the spinal needle insertions are planned for applying the intrathecal injections * Participation in any clinical investigation within 4 weeks prior to dosing or longer if required by local regulations * Patients who are unconscious
