The primary endpoint in the MAGIC study was achieved. The percentage of patients who achieved a Complete Response was significantly higher in the Sustol arm compared with the comparator arm (P=0.014). Significant benefit was also observed in the reduction in episodes of nausea. Data from a previous Phase 3 study of more than 1,300 patients, which was previously submitted to the FDA, demonstrated Sustol’s efficacy in the prevention of acute and delayed CINV associated with MEC regimens and acute CINV associated with HEC regimens.
