BiRd regimen consisting of clarithromycin and Rd is safe and effective in NDMM. It can significantly increase ORR (up to 90.3%) , relief depth (≥VGPR), and prolong PFS to 43 months. In our previous study, thirty RRMM patients treated with BiRd regimen in 6 centers in China benefited.It suggested that BiRd regimen may not only improve overall efficacy of RRMM , especially long-term benefits, but also reverse Rd resistance in patients who fail to achieve any remission after multiline therapy.The study is a Prospective, Multicenter, Single Arm, Phase II Clinical Trial, which intend to recruit first relapse MM patients over 18 years old. Once included, patients will receive the treatment of Clarithromycin Lenalidomide Dexamethasone (BiRd) Regimen. (Clarithromycin 500mg，po，bid，d1-21; Lenalidomide 25mg，po，daily，d1-21 (dose according to creatinine clearance rate); Dexamethasone 20mg，po，daily，d1-2, 8-9,15-16, 22-23) And we will evaluate efficacy and adverse events of the BiRd regimen at a point of time predetermined.

The purpose of this study is to evaluate the clinical efficacy and safety of ISV-502 compared to AzaSite® alone, Dexamethasone alone, and vehicle in the treatment of subjects with Non-bacterial Blepharitis.
