Pharmacokinetics of DMF and the Effects of DMF on Exploratory Biomarkers

Phase 4
Completed
Conditions
Multiple Sclerosis
Interventions
Drug: BG00012 (DMF) (Tecfidera®.)
Registration Number
NCT02683863
Lead Sponsor
Multiple Sclerosis Center of Northeastern New York
Brief Summary

The purpose of this study is to explore whether DMF (Dimethyl Fumarate) or MMF (monomethyl fumarate) its main bioactive metabolite, is capable of entering the central nervous system in SPMS patients that are being treated with Tecfidera®. PK samples (pharmacokinetics - or the amount of study drug in blood) will be tested to compare with PK samples, the amount of study drug, in spinal fluid (CSF).

Secondary Outcome Measures
NameTimeMethod
A secondary objective is to assess the effects of DMF on RNA samples from CSF cellular pellet for transcriptionomics in the CSF of subjects with SPMS.at 28 weeks

RNA samples from CSF cellular pellet for transcriptionomics.

A secondary objective is to assess the effects of DMF on PD biomarkers downstream of Nrf2 in the CSF of subjects with SPMS.at 28 weeks

PD biomarkers downstream of Nrf2, such as NAD(P)H hydrogenase \[quinone 1\], heme oxygenase-1, and aldo-keto reductase family 1 member B8 that have not been evaluated in CNS.

A secondary objective is to assess the effects of DMF on biomarkers of inflammation in the CSF of subjects with SPMS.at 28 weeks

Biomarkers of inflammation (e.g., osteopontin, B cell activating factor, chemokines, and matrix metalloproteinase 9), which may reflect pathogenesis in SPMS.

A secondary objective is to assess the effects of DMF on biomarkers of neuroaxonal damage in the CSF of subjects with SPMS.at 28 weeks

Biomarkers of neuroaxonal damage (e.g., neurofilament, myelin basic protein, glial fibrillary acidic protein, and neural cell adhesion molecule), which may reflect pathogenesis in SPMS.

A secondary objective is to assess the effects of DMF on biomarkers of oxidative stress in the CSF of subjects with SPMS.at 28 weeks

Biomarkers of oxidative stress (e.g., myeloperoxidase, 8-Oxo-2'-deoxyguanosine and RNA biomarkers), which may reflect pathogenesis in SPMS

A secondary objective is to assess the effects of DMF on myelin lipid biomarkers in the CSF of subjects with SPMS.at 28 weeks

Myelin lipid biomarkers (e.g., cholesterol, galactoceramide, sulfatides, and sphingomyelin), which may correlate with disability progression in MS patients.

A secondary objective is to assess the effects of DMF on pharmacogenomic biomarkers in the CSF of subjects with SPMS.at 28 weeks

Pharmacogenomic biomarkers: DNA analysis from blood samples.
