Evidence outlook · lead readout

NCT02725515 · Systemic Lupus Erythematosus

The lead readout missed its primary endpoint. The grade and rationale below record what the trial was designed to show and what it found.

NCT02725515: The study randomized 105 participants to XmAb5871 or placebo and used quadruple blinding. Its clinical primary endpoint was not met: 21 of 50 XmAb5871-treated patients versus 12 of 42 placebo-treated patients avoided loss of disease activity improvement at Day 225 (p=0.1830), despite a favorable statistically significant secondary time-to-loss result.
