Head-to-head evidence
Ganaxolone vs Staccato Alprazolam
Same mechanism, same race: design-graded trial evidence for both assets, with the grading rationale shown. Grades describe the quality of the evidence, never the merits of either security.
Epilepsy
Shared mechanism: GABA-A receptor · full Epilepsy pipeline
Ganaxolone
Marketed by Immedica Pharma AB
NCT01963208 · Phase 3 · completed
The primary phase was well controlled, with randomized quadruple blinding, placebo comparison, and 350 analyzed participants, and it used the clinical endpoint of change in seizure frequency. However, the primary endpoint was missed: the difference between ganaxolone and placebo was not statistically significant (p=0.1788), so the study provides well-designed but inconclusive evidence.
Staccato Alprazolam
Developed by UCB
NCT03478982 · Phase 2 · completed
The study randomized participants to Staccato alprazolam or matching placebo and was described as quadruple-blind, with 156 participants enrolled and 38, 38, and 40 participants in the evaluable 1.0-mg, 2.0-mg, and placebo groups, respectively. Its primary clinical endpoint—seizure cessation within 2 minutes without recurrence for 2 hours—was statistically significantly better with both alprazolam doses than with placebo.
