No graded featured trial for this indication yet; the grade above reflects that absence, not a judgment.
PT001

NCT03358147 · Phase 2/3 · completed
The study was randomized and quadruple-masked for the placebo comparison, included 1,077 participants, and used placebo and open-label active comparators. Its primary measure was a lung-function surrogate rather than a hard clinical outcome, and although the reported PT001 values were numerically higher than placebo, whether the prespecified primary comparison was statistically significant is not stated.
