NCT00635505 · Phase 3 · terminated
In this trial, Proventil-HFA is the established reference product that the investigational Armstrong's albuterol-HFA is being compared against, rather than the agent under primary evaluation itself, and no results have been posted yet.
Proventil

NCT00577655 · Phase 3 · completed
The trial randomized 103 children to albuterol or placebo and masked participants, caregivers, investigators, and outcome assessors. Its primary measures were physiologic lung-function outcomes rather than hard clinical outcomes; the FEV1 comparison was statistically significant, while the PEF comparison was not significant at the prespecified threshold, so the findings were mixed.
