This two-part trial will assess the safety, tolerability, pharmacokinetics, and efficacy of AXER-204 administered by lumbar puncture and slow bolus infusion. Part 1 will evaluate the safety, tolerability, and pharmacokinetics of single ascending doses of AXER-204. Part 2 will evaluate the safety, tolerability, pharmacokinetics, and efficacy of repeated doses AXER-204 in comparison to placebo.


AXER-204 is a human fusion protein that acts as a soluble decoy/trap for the myelin-associated inhibitors of axonal growth known as Nogo-A, MAG, and OMgp. AXER-204 and a surrogate protein used in early preclinical studies have been found to promote axon growth and recovery of function in animal models of spinal cord injury.

Part 1 of the trial is a multicenter, open-label, single ascending dose study in participants with chronic cervical spinal cord injury. Four cohorts of 6 participants each are planned, with participants within each cohort expected to receive the same dose of AXER-204.

Part 2 is a multicenter, randomized, double-blind, placebo-controlled, repeat dose study in chronic cervical spinal cord injury participants. Approximately 32 participants will be randomized (ratio 1:1) to receive repeated doses of AXER-204 or placebo (a phosphate buffered saline formulation). The dose level and dose frequency will be dependent upon outcomes from Part 1.
