Merck Serono Completes Patient Enrollment in CLARITY Phase III Pivotal Clinical Trial of Oral CladribineOral Cladribine on Track to Become First Oral Disease Modifying Treatment for Multiple Sclerosis
GENEVA, Switzerland, January 16 (HSMN NewsFeed) -- Merck Serono (virt-x: SEO and NYSE: SRA) announced today that patient enrollment has been completed in the CLARITY (CLAdRIbine Tablets Treating MS OrallY) study, a Phase III pivotal clinical trial evaluating the efficacy and safety of Merck Serono's proprietary oral formulation of cladribine for the treatment of relapsing forms of multiple sclerosis (MS).
"The completion of patient enrollment into the CLARITY pivotal trial is a major milestone in the development program of oral cladribine," said Franck Latrille, Merck Serono's Head of Product Development. "It brings us one step closer to our objective of offering patients the first oral therapy for first line treatment of multiple sclerosis, with the convenience of short courses of therapy given intermittently."
The CLARITY study is a two-year (96 weeks), randomized, double-blind, placebo-controlled, international trial. It enrolled more than 1,300 patients and will provide data on key endpoints including clinical relapses, disability progression and magnetic resonance imaging (MRI). Study participants have been enrolled in one of the three arms of the study to receive one of two different dose regimens of oral cladribine or matching placebo tablets. In the study, oral cladribine is given in two or four treatment cycles in the first year, with each cycle consisting of daily administration for five consecutive days, which means study patients take oral cladribine therapy for only 10 or 20 days during the year. In the second year, two treatment cycles are administered.
The increased convenience resulting from the oral intermittent administration of oral cladribine has the potential to address an important unmet medical need in patients with MS.
Oral cladribine was designated a Fast Track product by the US Food and Drug Administration (FDA) in September 2006. Under Fast Track designation, oral cladribine is eligible for Priority Review and the FDA may consider portions of the marketing application for review before the New Drug Application (NDA) is completed.
About oral cladribine
Merck Serono's proprietary oral formulation of cladribine is currently being evaluated in Phase III as a treatment for patients with relapsing forms of multiple sclerosis (MS). Cladribine is a small molecule that interferes with the behavior and the proliferation of certain white blood cells, particularly lymphocytes, which are involved in the pathological process of MS. Through its differentiated mechanism of action, oral cladribine may offer a safe and effective new option to patients with MS.
About Merck Serono and multiple sclerosis
Merck Serono is a leader in multiple sclerosis (MS) with Rebif® (interferon beta-1a), a disease-modifying drug used to treat relapsing forms of MS, which is registered in more than 80 countries worldwide.

Additional therapeutic options are currently under development at Merck Serono, including oral cladribine, currently in Phase III and potentially the first oral therapy for MS, as well as several products in early stage development including: osteopontin, an MMP-12 inhibitor, a JNK inhibitor and interferon beta:Fc. Merck Serono also is taking a leading role in developing an understanding of the role of genetics in MS, with a whole genome scan currently underway.
About multiple sclerosis
Multiple sclerosis (MS) is a chronic, inflammatory condition of the nervous system and is the most common, non-traumatic, neurological disease in young adults. The World Health Organization estimates that up to 2.5 million people suffer from MS worldwide. While symptoms can vary, the most common symptoms of MS include blurred vision, numbness or tingling in the limbs and problems with strength and coordination. The relapsing forms of MS are the most common.
