FDA accepts submission for cladribine tablets as potential treatment for relapsing multiple sclerosis

A new drug application for cladribine tablets as a potential treatment for relapsing remitting multiple sclerosis (RRMS) patients has been accepted for consideration by the US Food and Drug Administration (FDA).

The acceptance indicates that the FDA has found the pharmaceutical company Mercks' resubmission sufficiently complete to permit a substantive review. The resubmission is in response to the Complete Response Letter issued by the FDA in 2011 requesting an improved understanding of safety risks and the overall benefit-risk profile.

The acceptance of the new drug application follows global approvals of cladribine tablets under the trade name Mavenclad in 38 countries since August 2017, including the European Union (EU), Canada, Australia, Israel, Argentina, United Arab Emirates, Chile and Lebanon. Additional filings in other countries are planned for 2018.

Cladribine tablets is an investigational agent that has been studied as a short-course (a maximum of 20 days of treatment over two years) oral therapy that is thought to selectively target lymphocytes, which may be integral to the pathological process of relapsing MS.

"Most available MS therapies require continued, regular dosing of medication. A treatment approach consisting of short, infrequent oral treatment cycles may help lower the treatment burden for patients," said Thomas Leist, Director of the Comprehensive Multiple Sclerosis Center at Jefferson University Hospitals. "Based on additional clinical research in recent years, we know more about the treatment course, safety, and impact of cladribine tablets across several key measures of MS, and hope it will be made available to the US MS community."

The application acceptance includes close to 12,000 patient years of data with over 2,700 patients included in the clinical trial program, and up to 10 years of safety data in some patients. The clinical development program included data from three Phase III trials, CLARITY, CLARITY EXT and ORACLE MS, the Phase II ONWARD study and long-term follow-up data from the eight-year prospective registry, PREMIERE.
