Condition(s) targeted: Multiple Sclerosis

Intervention: Cladribine (Drug); Cladribine (Drug); Placebo (Drug); Rebif® new formulation (RNF) (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: EMD Serono

Official(s) and/or principal investigator(s):

Summary

A randomized, double-blind, clinical trial to assess the safety and efficacy of two doses of oral cladribine versus placebo in subjects who had a first clinical demyelinating event (clinically isolated syndrome). Subjects in either the cladribine or placebo group may also enter treatment periods with open-label interferon-beta or open-label cladribine depending upon the disease status. The primary objective of this study is to evaluate the effect of two dosage regimens of oral cladribine versus placebo on the time to conversion to multiple sclerosis (MS) (from randomization) according to the Poser criteria in subjects with first clinical demyelinating event at high risk of converting to MS.

Clinical Details

Official title: A Phase III, Randomized, Double-blind, Placebo-controlled, Multi-center Clinical Trial of Oral Cladribine in Subjects With a First Clinical Event at High Risk of Converting to MS

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment

Primary outcome: Time to Clinically Definite Multiple Sclerosis (CDMS) Conversion Represented by Kaplan-Meier Estimates of the Cumulative Percentage of Participants With CDMS

Secondary outcome:

Time to Develop Multiple Sclerosis (MS) Conversion According to the Revised McDonald Criteria (2005) Represented by Kaplan-Meier Estimates of the Cumulative Percentage of Participants With McDonald MS

Number of Combined Unique Active (CUA) Lesions, New or Enlarging Time Constant 2 (T2) Lesions, and New or Persisting Time Constant 1 (T1) Gadolinium Enhanced (Gd+) Lesions Per Participant Per Scan

Number of Participants With Adverse Events (AEs) and Serious Adverse Events (SAEs)

Detailed description: This will be a randomized, double blind, three-arm, placebo-controlled, multi-center trial to evaluate the safety and efficacy of oral cladribine versus placebo in the treatment of subjects who have sustained a first clinical demyelinating event within 75 days prior to the Screening. Subjects must have a minimum of 2 clinically silent lesions on the Screening magnetic resonance imaging (MRI). The study will include a pre-study evaluation period (Screening period: between 10 and 28 days prior to the start of treatment with blinded study medication (oral cladribine or placebo). Depending upon the clinical course of their MS, subjects will then proceed from the ITP to either the Maintenance Treatment Period (with open-label interferon-beta treatment) or LTFU period (with either open-label low-dose cladribine or no additional treatment (if no progression to MS has been noted after the initial treatment period). The single primary endpoint for the overall study, which will be determined during the ITP, is time to conversion to MS (from randomization), according to the Poser criteria. For every subject, eligibility for study enrollment and entry into each of the study periods, and diagnosis of conversion to either McDonald MS or CDMS must be confirmed and approved by a Sponsor appointed study Adjudication Committee.

Eligibility

Minimum age: 18 Years. Maximum age: 55 Years. Gender(s): Both.

Criteria:

Inclusion Criteria:

- Male or female between 18 and 55 years old, inclusive

- Weighed between 40 to 120 kilogram (kg), inclusive

- Subject has experienced a single, first clinical event suggestive of MS within 75

days prior to the Screening visit, (clock starts 24 hours after onset). The event must be a new neurological abnormality present for at least 24 hours, either mono- or polysymptomatic

- Subject has at least two clinically silent lesions on the T2-weighted MRI scan, at

screening, with a size of at least 3 millimeter (mm), at least one of which is ovoid or periventricular or infratentorial on screening MRI

- Subject has EDSS 0 - 5. 0 at Screening

- Subject has no medical history or evidence of latent tuberculosis infection (LTBI) or

active tubercular disease, as evidenced by the Mantoux tuberculosis (TB) skin test or a comparable sensitive test according to local regulations/guidelines (if the Mantoux test is not available), and/or a chest X-ray

- Subject has normal hematological parameters at Screening, as defined by the central

laboratory that performed all the assessments

- If female, she must:

- be neither pregnant nor breast-feeding, nor attempting to conceive and

- use a highly effective method of contraception throughout the entire duration of

the study and for 90 days following completion of the last dose of study medication. A highly effective method of contraception is defined as those which result in a low failure rate (that is less than 1 percent per year) when used consistently and correctly such as implants, injectables, combined oral contraceptives, some intrauterine devices, sexual abstinence or vasectomized partner, or

- be post-menopausal or surgically sterilized (Note: for Danish sites only,

subjects should use a hormonal contraceptive or intrauterine device for the duration of the trial)

- Male subjects must be willing to use contraception to avoid impregnating partners

throughout the study, and for 90 days following the last dose of study medication

- Be willing and able to comply with study procedures for the duration of the study

- Subject has to provide written informed consent voluntarily, including, for United

states of America (USA), subject authorization under Health Insurance Portability and Accountability Act (HIPAA), prior to any study-related procedure that is not part of normal medical care

- Subject has refused any treatment already available for clinically isolated syndrome

(CIS) such as interferons or glatiramer acetate, at the time of entry into the Initial Treatment Period of this study Exclusion Criteria:

- Subject has a diagnosis of MS (per McDonald criteria, 2005)

- Subject has any other disease that could better explain the subject's signs and

symptoms

- Subject has complete transverse myelitis or bilateral optic neuritis

- Subject using or has used any other approved MS disease modifying drug (DMD)

- Subject has used any investigational drug or undergone an experimental procedure

within 12 weeks prior to Study day 1

- Subject received oral or systemic corticosteroids or adrenocorticotropic hormone

(ACTH) within 30 days prior to screening MRI. The MRI had to be performed 30 days after the oral or systemic corticosteroids or ACTH treatment. In case this interfered with MRI timing the screening period could be extended accordingly.

- Subject has abnormal total bilirubin, or aspartate aminotransferase (AST) or alanine

aminotransferase (ALT) or alkaline phosphatase greater than 2. 5 times the upper limit of normal

- Subject suffered from current autoimmune disease other than MS

- Subject suffered from psychiatric illness (including history of, or concurrent,

severe depressive disorders and/or suicidal ideation) that in the opinion of the investigator creates undue risk to the subject or could affect compliance with the study protocol

- Subject suffered from major medical illness such as cardiac (for example angina,

congestive heart failure or arrhythmia), endocrinologic, hepatic, immunologic, metabolic, renal, pulmonary, gastrointestinal, dermatologic, or other major disease that would preclude the administration of oral cladribine

- Subject has a history of seizures not adequately controlled by medications

- Subject has a known allergy to cladribine, interferon-beta, the excipient(s) of the

study medications, or to gadolinium- diethylenetriamine penta-acetic acid (DTPA)

abnormalities

- Subject has a history of active or chronic infectious disease or any disease that

compromises immune function (for example human immunodeficiency virus positive [HIV+], human T-lymphotrophic virus [HTLV-1], Lyme disease, latent tuberculosis infection [LTBI] or TB, insulin-dependent diabetes).

- Subject has received experimental MS treatment

- Subject has a history of alcohol or drug abuse

- Subject has intolerance or any contraindication to both paracetamol (acetaminophen)
