Cladribin (1) – Mavenclad®

• Clinical trials
  • To demonstrate the additional benefit, the pharmaceutical manufacturer has submitted the CLARITY and CLARITY EXTENSION registration trials. Both trials are multicentre, randomised, double-blind, placebo-controlled Phase III trials.

a) for patients who have not yet received any disease-modifying therapy

• For adult patients with highly active relapsing-remitting multiple sclerosis, defined by clinical or imaging findings, who have not yet received disease-modifying therapy, the additional benefit of cladribine is not proven.
• The additional benefit is not proven.
• Side effects
  • Overall, there are therefore no usable data available to demonstrate the additional benefit of cladribine compared with the appropriate comparator therapy—interferon beta-1a, interferon beta-1b or glatiramer acetate—taking the marketing authorisation into account.

b) for patients with highly active disease despite treatment with a disease-modifying therapy

• For adult patients with highly active relapsing-remitting multiple sclerosis, defined by clinical or imaging findings, who have highly active disease despite treatment with a disease-modifying therapy, the additional benefit of cladribine is not proven.
• An additional benefit is not proven.
• morbidity
  • The pharmaceutical manufacturer presents results for the adjusted indirect comparison of cladribine with fingolimod only for endpoints in the morbidity category (annual relapse rate, disability progression, disability progression and new or newly enlarged T2 lesions).
• Side effects
  • In particular, data on side effects are therefore completely lacking for the benefit assessment, making it impossible to weigh up the benefits and harms of the treatment options.
• Due to the lack of data on the endpoint categories of side effects, mortality and health-related quality of life, as well as uncertainties regarding the comparability of the study populations, the results of the indirect comparison are therefore not used for the benefit assessment.
