Selvom 170 ud af 351 patienter, som blev randomiseret til placebo/ dexamethason, modtog behandling med lenalidomid/ dexamethason, efter at studierne var blevet afblindet, viste den poolede analyse af den samlede overlevelse (OS) en statistisk væsentlig overlevelsesfordel for lenalidomid/ dexamethason sammenlignet med placebo/ dexamethason (hazard ratio = 0, 75, 95% konfidensinterval = [0, 59; 0, 95], p = 0, 015).
Despite the fact that 170 out of the 351 patients randomised to placebo/dexamethasone received treatment with lenalidomide/dexamethasone after the studies were unblinded, the pooled analysis of OS demonstrated a statistically significant survival advantage for lenalidomide/dexamethasone relative to placebo/dexamethasone (hazard ratio = 0.75, 95% CI = [0.59, 0.95], p=0.015).
