Key clinical point: Cladribine tablets had lower annualized relapse rate (ARR) vs. interferon, glatiramer acetate, and dimethyl fumarate for relapsing-remitting multiple sclerosis (RRMS) in the first 2 years; a similar ARR vs. fingolimod; and a higher ARR vs. natalizumab.
Major finding: Cladribine demonstrated significantly lower ARR vs. interferon (relapse ratio [RR], 0.48; P less than .001), glatiramer acetate (RR, 0.49; P less than .001), and dimethyl fumarate (RR, 0.6; P = .001). No significant differences in ARR were observed when compared with fingolimod (RR = 0.74; P = .24), whereas higher ARR was observed vs. natalizumab (RR, 2.13; P = .014).
Study details: This study compared the efficacy of cladribine vs. other approved drugs in patients with RRMS by matching randomized controlled trial (CLARITY trial; cladribine tablets vs. placebo; n = 945) to observational data (Italian multicenter database i-MuST; n = 2,204).
