MAVENCLAD is indicated for the treatment of relapsing forms of multiple sclerosis (MS), to include relapsing-remitting disease and active secondary progressive disease, in adults. Because of its safety profile, use of MAVENCLAD is generally recommended for patients who have had an inadequate response to, or are unable to tolerate, an alternate drug indicated for the treatment of MS

MAVENCLAD is available as 10 mg tablets. The tablets are uncoated, white, round, biconvex, and engraved with a "C" on one side and "10" on the other side.

MAVENCLAD is contraindicated:

The following serious adverse reactions and potential risks are discussed, or discussed in greater detail, in other sections of the labeling:

There is no experience with overdose of MAVENCLAD. Lymphopenia is known to be dose- dependent. Particularly close monitoring of hematological parameters is recommended in patients who have been exposed to an overdose of MAVENCLAD

There is no known specific antidote to an overdose of MAVENCLAD. Treatment consists of careful observation and initiation of appropriate supportive measures. Discontinuation of MAVENCLAD may need to be considered. Because of the rapid and extensive intracellular and tissue distribution, hemodialysis is unlikely to eliminate cladribine to a significant extent.

MAVENCLAD contains the nucleoside metabolic inhibitor cladribine, which is a white or almost white, non-hydroscopic, crystalline powder with the molecular formula C

The structural formula isshown below:

Cladribine is stable at slightly basic and at neutral pH. The main degradation pathway is hydrolysis and at acidic pH significant decomposition occurs with time. The ionization behavior of the molecule over the pH range 0 to 12 is characterized by a single pKa of approximately 1.21.

MAVENCLAD is provided as 10 mg tablets for oral use. Each MAVENCLAD 10 mg tablet contains cladribine as an active ingredient and hydroxypropyl betadex, magnesium stearate, and sorbitol as inactive ingredients.

The efficacy of MAVENCLAD was demonstrated in a 96-week randomized, double-blind, placebo-controlled clinical study in patients with relapsing forms of MS (Study 1; NCT00213135).

Patients were required to have at least 1 relapse in the previous 12 months. The median age was 39 years (range 18 to 65) and the female-to-male ratio was approximately 2:1. The mean duration of MS prior to study enrollment was 8.7 years, and the median baseline neurological disability based on Kurtzke Expanded Disability Status Scale

1,326 patients were randomized to receive either placebo (n = 437), or a cumulative oral dosage of MAVENCLAD 3.5 mg per kg (n = 433) or 5.25 mg per kg body weight (n = 456) over the 96-week study period in 2 treatment courses. Patients randomized to the 3.5 mg per kg cumulative dose received a first treatment course at Weeks 1 and 5 of the first year and a second treatment course at Weeks 1 and 5 of the second year

The primary outcome of Study 1 was the annualized relapse rate (ARR). Additional outcome measures included the proportion of patients with confirmed disability progression, the time to first qualifying relapse, the mean number of MRI T1 Gadolinium-enhancing (Gd+) lesions, and new or enlarging MRI T2 hyperintense lesions. Disability progression was measured in terms of a 3-month sustained change in EDSS score of at least one point, if baseline EDSS score was between 0.5 and 4.5 inclusively, or at least 1.5 points if the baseline EDSS score was 0, or at least 0.5 point if the baseline EDSS score was at least 5, over a period of at least 3 months.

MAVENCLAD 3.5 mg per kg significantly lowered the annualized relapse rate. The results from Study 1 are presented in Table 4.
