E.2.1 | Main objective of the trial |
The objectives of this study in MS subjects treated with prolonged-release fampridine 10 mg twice daily compared with subjects treated with placebo are:
To assess the effect of prolonged-release fampridine over 24 weeks on the following parameters to explore endpoints for the Phase 3 study: self-assessed walking disability, dynamic and static balance, subjective impression of well-being, subjects’ global impression of change in walking
To evaluate the safety and tolerability of prolonged-release fampridine. |

Pharmacogenomic Assessments (Optional)
Investigator participation in pharmacogenomic assessment is optional and contingent upon approval by his/her ethics committee or Institutional Review Board (IRB). If participating, the potential subjects will also be provided with the option to decline the pharmacogenomic assessment without affecting participation in the main study. Informed consent will be documented by the Investigator and recorded on the CRF. If the Investigator is not participating or the pharmacogenomic assessment is not approved by his/her ethics committee/IRB, the relevant section of the informed consent form (ICF) will not be applicable to that site.
Whole blood samples for DNA testing will be collected at baseline with subject consent (requires written informed consent). Experience with treatment in MS shows that there is heterogeneity in clinical response, and some of the heterogeneity may be associated with genetic variation in patients. The pharmacogenomic analysis will explore identification of specific genetic polymorphisms associated with study treatment response.
DNA may be used for genome-wide or candidate gene single nucleotide polymorphism (SNP) analyses. Allelic variants at SNP loci will be tested for association with safety and efficacy measurements from the study.
Refer to Section 4.2 for the timing of assessments and to Section 4.3 for additional detail regarding the assessments. |
