Crexont (IPX203) vs ND0612
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.

Crexont (IPX203)
Marketed by Amneal Pharmaceuticals
NCT03670953 · Phase 3 · completed
The study was randomized, quadruple-blind, double-dummy, and active-controlled, with 506 participants entering the randomized maintenance period and 495 contributing primary-endpoint data. The clinical primary endpoint was met: IPX203 produced a significantly greater improvement in daily “good on” time than immediate-release carbidopa-levodopa (p=0.0194).

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.
