摘要

The standard "disease-modifying" treatment for patients with relapsing-remitting multiple sclerosis is interferon beta, despite its modest efficacy and many adverse effects. None of the other disease-modifying drugs have a better harm-benefit balance, and in some cases it is clearly unfavourable (1). Cladribine (Mavenclad0, Merck) is a purine analogue with prolonged cytotoxic effects on B and T lymphocytes and therefore immunosuppressive effects. It is authorised in hairy-cell leukaemia (2,3). In 2017, an oral form of cladribine was authorised in the European Union for patients with relapsing multiple sclerosis deemed "highly active", administered in 2 short courses one year apart (3). Cladribinewas mainly evaluated in this situation in one double-blind randomised placebo-controlled trial in 1326 patients with multiple sclerosis.They did not have severe disability and most (70%) had had only one relapse in the year preceding the trial. About 80% of patients in the cladribine group had no new relapses over a 2-year period, versus 61% in the placebo group (p < 0.001), although no convincing effect was shown on progression of their disability. In subgroup analyses, which were not planned in the protocol and therefore provide only weak evidence, cladribine appeared to reduce the relapse rate to a similar extent in patients with "highly active" disease (2,3).
