Spinogenix is moving its lead candidate, SPG302, closer to a registrational trial after promising results in a mid-stage study for amyotrophic lateral sclerosis (ALS).
In the Phase IIa study (NCT05882695), SPG302 demonstrated a strong safety profile, meeting its primary endpoint of safety and tolerability with no treatment-emergent serious adverse events during six months of daily dosing in ALS patients.
The drug showed encouraging efficacy by stabilizing or improving the rate of ALS-associated decline in 82% of patients, measured by the revised ALS Functional Rating Scale (ALSFRS-R) at the end of treatment.
Compared to historical controls from the PRO-ACT database—the largest publicly integrated ALS clinical trial dataset—patients on SPG302 experienced a 76% slower decline over six months.
Electroencephalogram (EEG) recordings taken during the trial revealed “improvements in ALS-associated patterns,” reinforcing the drug’s potential to delay functional loss in ALS.
“Improvements in ALS-associated patterns,” which Spinogenix says supports the drug’s observed capacity to stave off functional decline.
Spinogenix’s SPG302 offers promising advances in slowing ALS progression while maintaining safety during extended daily use, justifying further late-stage clinical evaluation.
