GlaxoSmithKline
  Purpose
This is a study to count the number of white blood cells in the cerebrospinal fluid and blood at the beginning and end of treatment with firategrast and at 4 and 12 weeks after stopping firategrast. Cerebrospinal fluid flows through and protects the brain and spinal cord. It is important to understand what happens to the number of white blood cells because they are important in preventing infections.

  • Change from Baseline in number of CD34+ cells in the blood [ Time Frame: Baseline (Week 0) and Week 4, 24, 28, 36 ]
    Blood sample was examined to test the mobilization of CD34+ early hematopoietic progenitor cells from the bone marrow at Baseline (Week 0), Week 4, Week 24, Week 28 and Week 36. CD34+ was measured using two different approaches by the independent assessor: a.

With a CD45 SSH added and the analysis was conducted by the independent assessor only. All the data presented are based on results from independent assessor. Baseline was defined at Week 0. Change from Baseline is the value at indicated time points minus the Baseline value.

  • Number of participants with adverse events (AEs) and Serious adverse events (SAEs) [ Time Frame: Up to Week 24 ]
    AE was defined as any untoward medical occurrence in a participant, temporally associated with the use of a medicinal product, whether or not considered related to the medicinal product. SAE was any untoward medical occurrence that, at any dose results in death, was life threatening, required hospitalization or prolongation of existing hospitalization, resulted in disability/incapacity, was a congenital anomaly/birth defect or was considered as medically significant. On-treatment AEs and SAEs have been presented.

  • Cumulative number of new gadolinium-enhancing lesions at Week 24 [ Time Frame: Week 24 ]
    The number of new gadolinium-enhancing lesions was determined by magnetic resonance imaging (MRI) scan. The cumulative number of new gadolinium-enhancing lesions at 24 weeks of treatment was derived as the sum of new gadolinium-enhancing lesions counted at all visits from Week 4 up to Week 24. In the event that a participant had missing MRI data for a gadolinium enhanced lesion parameter during the on-treatment period (scans at Weeks 4-24 inclusive), the missing value was imputed using the mean value for that parameter for all non-missing scans during the treatment period.

  • Cumulative volume of new gadolinium-enhancing lesions at Week 24 [ Time Frame: Week 24 ]
    The volume of new gadolinium-enhancing lesions was determined by MRI scan. The cumulative volume of new gadolinium-enhancing lesions was calculated at each visit from Week 4 up to Week 24. In the event that a participant had missing MRI data for a gadolinium enhanced lesion parameter during the on-treatment period (scans at Weeks 4-24 inclusive), the missing value was imputed using the mean value for that parameter for all non-missing scans during the treatment period.

  • Cumulative number of persistent gadolinium-enhancing lesions at Week 24 [ Time Frame: Week 24 ]
    The number of persistent gadolinium-enhancing lesions was determined by MRI scan. The cumulative number of persistent gadolinium-enhancing lesions at 24 weeks of treatment was derived as the sum of persistent gadolinium-enhancing lesions counted at all visits from Week 4 up to Week 24. In the event that a participant had missing MRI data for a gadolinium enhanced lesion parameter during the on-treatment period (scans at Weeks 4-24 inclusive), the missing value was imputed using the mean value for that parameter for all non-missing scans during the treatment period.

  • Cumulative total number of enhancing Lesions at Week 24 [ Time Frame: Week 24 ]
    The total number of gadolinium-enhancing lesions was determined by MRI scan. The cumulative total number gadolinium-enhancing lesions at 24 weeks of treatment was derived as the sum of the new and persistent gadolinium-enhancing lesions counted at all visits from Week 4 up to Week 24. In the event that a participant had missing MRI data for a gadolinium enhanced lesion parameter during the on-treatment period (scans at Weeks 4-24 inclusive), the missing value was imputed using the mean value for that parameter for all non-missing scans during the treatment period.

  • Plasma and CSF levels of firategrast [ Time Frame: Week 24, 28 and 36 ]
    Pharmacokinetic sampling for plasma and CSF levels of firategrast was done on Week 24 of treatment period and Week 28 and 36 of core follow up period, however the results for these parameters were not analyzed.

  • The relationship between plasma concentration of firategrast and lymphocyte count in the CSF [ Time Frame: Week 24, 28 and 36 ]
    Sampling to determine concentration of firategrast and lymphocyte count in the CSF was supposed to be done on Week 24 of treatment phase and Week 28 and 36 of core follow up period to investigate any relationship between lymphocyte counts and systemic exposure to firategrast and its metabolite GW786375X. There was no quantifiable concentrations of firategast or its metabolite GW786375X, hence, the results were not analyzed.

  • The relationship between plasma concentration of firategrast and lymphocyte count in the blood [ Time Frame: Week 24, 28 and 36 ]
    Sampling to determine concentration of firategrast and lymphocyte count in the blood was supposed to be done on Week 24 of treatment phase and Week 28 and 36 of core follow up period to investigate any relationship between lymphocyte counts and systemic exposure to firategrast and its metabolite GW786375X, however, the results were not analyzed.

  • The relationship between the presence of the A allele of rs887829 and bilirubin levels [ Time Frame: Baseline (Week 0) ]
    Participants were assessed for the presence of A allele of rs887829 which is associated with Gilbert's syndrome. Gilbert's syndrome is benign and characterized by transient increases in bilirubin levels (>1.5XUpper limit of normal [ULN]). Participants who were carrying two copies of A allele of rs887829, suggested that elevations in bilirubin (maximum total bilirubin [MTB] >1.5xULN, >1.0 to 1.5xULN and less than or equal to 1.0xULN) were due to benign Gilbert's syndrome. Genotypes AA, AG and GG were analyzed.

Exclusion criteria:

Subjects meeting any of the following criteria must not be enrolled in the study:

  • Any findings at Screening on the MRI of the brain other than MS, except for benign findings that (in the opinion of the central MRI reading site and local site investigator) require no further evaluation or treatment and do not impact patient's neurological health (e.g. small arachnoid cysts, venous angiomas).
  • Uncontrolled or any active bacterial, viral, or fungal infection. Any previous serious infections should be discussed with the GSK medical monitor (e.g. opportunistic or atypical infections).
