Protocol EG-501-2.1 is a Phase 2, multi-site, randomized, double-blind, placebo-controlled trial evaluating the efficacy, safety, and tolerability of EG-501 for the treatment of cognitive impairment in systemic lupus erythematosus (SLE). The primary objective was to assess whether a 12-week EG-501 regimen produces a statistically and clinically significant improvement in the Total Scale Index score of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS®), compared with matched placebo, in a precisely defined SLE population with objective cognitive impairment. Fifty-six (56) patients were randomized treatment, 30 to placebo group and 26 to EG-501 group. All but three patients were female. Median age was 44.0 and 45.5 for placebo and EG-501 groups, respectively. With patients recruited only from the US, racial distribution was about 2/3 white, 1/3 black, with ethnicity reflecting largely non-Hispanic demographics.
