Exclusion criteria
Exclusion criteria: • type of MS other than relapsing; • any disease other than MS that could better explain the subject's signs and symptoms; • any conditions that could interfere with the contrast-enhanced MRI, including an estimated glomerular filtration rate (eGFR) 450 ms (in case of doubt, UCB's responsible medical officer will be consulted and a joint documented decision will be made between investigator and UCB's medical officer); • any significant deviation from reference ranges for hepatic function as defined by either SGOT, SGPT, GGT, or AP elevated 3-fold or higher beyond the upper limit of the reference range or total bilirubin elevated 2-fold or higher beyond the upper limit of the reference range; • signs of silent infections, including positive tests for HIV1, HIV2, or Hepatitis B or Hepatitis C, or tuberculosis; • any condition possibly interfering with drug absorption; • known allergy to gadolinium-DTPA, and/or ingredients of the study drug formulation; • history of severe AEs to any drug; • participation in any clinical drug trial within 30 days prior to screening; • concomitant treatment with the CYP1A substrates mexiletine, propafenone, theophylline, verapamil or warfarin or statins (e.g., atorvastatin), or rosiglitazone, pioglitazone, repaglinide, amodiaquine and any other compound metabolized primarily through cytochrome P450 2C8, or protease inhibitors (e.g., ritonvavir), systemic triazole antifungals (e.g., ketoconazole) for either their interference with transport protein systems or for their strong inhibition of the P450 cytochrome pathway, or these drugs known for their potential to interfere with cardiac repolarization: amiodarone, arsenic trioxide, bepredil, budipine, cisapride, chinidine (quinidine), chloroquine, chlorpromazine, clarithromycin, disopyramide, dofetilide, domperidone, droperidol, erythromycin, halofantrine, haloperidol, ibutilide, levomethadyl, mesoridazine, methadone, pentamidine, pimozide, procainamide, sotalol, sparfloxacin, thioridazine • pre-treatment with the following substances prior to study participation within the following time frames: • at any time: rituximab, mitoxantrone or cyclophosphamide; total lymphoid irradiation; anti-lymphocyte monoclonal antibody treatment (e.g., anti-CD4, Campath-1H); cladribine, mycophenolate; • up to 30 days prior to baseline: any interferons, glatiramer acetate, corticosteroids and ACTH, IvIg, cyclosporine A, human antibodies, any other immunomodulating or immunosuppressive drugs including recombinant cytokines, any other putative or experimental MS treatment; any inoculation with attenuated live vaccines • six month prior to baseline: azathioprine or natalizumab. Treatment with natalizumab must not have been terminated due to lack of efficacy, however subjects with documented natalizumab neutralizing antibodies ma

| Main Objective: Compare the effects of 500 mg CDP323 twice daily on MS-related imaging parameters in subjects with relapsing MS (RMS) with the effects seen under placebo treatment in that population over a period of 24 weeks;Secondary Objective: - Compare CDP323's tolerability and safety in RMS subjects with placebo treatment in that population over a period of 24 weeks; - Compare the effects of CDP323 on the occurrence of relapses in RMS subjects with the effects seen under placebo treatment in that population over a period of 24 weeks; - Compare the effects of twice daily dosing of CDP323 vs once daily dosing of CDP323 including the related time course of a4/VCAM-1 binding between the two dosing regimen and placebo; - Characterize the main pharmacokinetic parameters of CDP323 and its metabolites in subjects suffering from RMS; - Assess potential withdrawal effects after termination of treatment with CDP323.;Primary end point(s): Primary Efficacy Variable Cumulative number of newly active lesions over 24 weeks as seen on standardized brain MRI scans. The following lesions are considered newly active: • new gadolinium (Gd) enhancement on T1-weighted images; • non-enhancing on T1-weighted images but new on T2-weighted images; • new enlargement on T2-weighted images but non-enhancing on T1-weighted images. Pharmacokinetic and Pharmacodynamic Variables • for all subjects, plasma concentrations of CDP323, CT7758, and CT533652-00 will be determined from samples taken during specified time points; a 'sparse' sampling schedule will be followed • population-kinetic methods may be used to describe derived pharmacokinetic parameters for CDP323, CT7758, and CT533652-00 • in a subset of centers suitable to set up the logistics for pharmacodynamic tests markers, such markers including VCAM1 binding may be determined; in addition, subjects participating in this pharmacodynamic sub-study will be asked to also undergo a more intense pharmacokinetic sampling schedule to allow an in | — |
