Head-to-head evidence
ND0612 vs WD-1603
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.

ND0612
Developed by NeuroDerm Ltd.
NCT02577523 · Phase 2 · completed
Participants were randomized to two ND0612 regimens, but the study was only single-blinded for outcome assessors, had no placebo or active-control arm, and was small with 19 participants per group. The clinical primary endpoint was daily OFF time; although the 24-hour regimen showed a numerically greater reduction, statistical significance for the comparison was not reported, so the result is unclear.
WD-1603
Developed by Hong Kong WD Pharmaceutical Co., Limited
NCT05036473 · Phase 2 · completed
This randomized, double-blind, placebo-controlled Phase 2 trial in early Parkinson's disease enrolled only 40 patients across three dose groups and placebo. All three doses of WD-1603 produced a statistically significant improvement in combined motor and daily-living function scores versus placebo at 27 days, with the largest effect at the highest dose (p=0.0003), but the very small sample size means these results need confirmation in a larger trial.
