      Primary Objective:&#xD;
&#xD;
      To collect blood samples in a new cohort of Relapsing Forms of Multiple Sclerosis (RMS)&#xD;
      participants who had developed immune thrombocytopenic purpura (ITP) after LEMTRADA&#xD;
      treatment, for future Deoxyribonucleic acid (DNA) analysis as part of a global biomarker&#xD;
      project assessing pre-identified candidate single nucleotide polymorphisms (SNPs) associated&#xD;
      to the development of ITP after LEMTRADA treatment in RMS participants.&#xD;

      One to 70 days, as screening and inclusion visit(s) were performed the same day or on&#xD;
      separate days with a maximum timeframe of 30 days apart. One visit was required for blood&#xD;
      draw. However, if a second visit occured, it took place within 40 days of the first visit.&#xD;

    <description>Each participant provided a maximum total of 69 milliliter of whole blood sample. Samples were collected in the following order: 1. Deoxyribonucleic acid (DNA) Paired box (PAX)gene tubes (2 tubes), 2. Ribonucleic acid (RNA) PAXgene tubes (2 tubes), 3. Ethylenediaminetetraacetic acid (EDTA) tubes for peripheral blood mononuclear cells (PBMCs) (5 tubes), 4. Serum Separator tube (SST) (1 tube), and 5. Dipotassium Ethylenediaminetetraacetic acid (K2EDTA) tube (1 tube); where DNA PAXgene tubes were used for DNA preparation, RNA PAXgene tubes for RNA preparation, EDTA for PBMC isolation, SST tubes for serum preparation and K2EDTA for plasma preparation. DNA was extracted from peripheral blood for future analysis.</description>

    <participant_flow>
      <recruitment_details>The study was conducted at a single site in the United States. A total of 14 participants were screened between 8 February 2019 to 11 December 2019, of which,1 participant was screen failure. Screen failures was mainly due to inclusion criteria not met.</recruitment_details>

Primary Objective:

      To collect blood samples in a new cohort of Relapsing Forms of Multiple Sclerosis (RMS)
      participants who had developed immune thrombocytopenic purpura (ITP) after LEMTRADA
      treatment, for future Deoxyribonucleic acid (DNA) analysis as part of a global biomarker
      project assessing pre-identified candidate single nucleotide polymorphisms (SNPs) associated
      to the development of ITP after LEMTRADA treatment in RMS participants.
One to 70 days, as screening and inclusion visit(s) were performed the same day or on
      separate days with a maximum timeframe of 30 days apart. One visit was required for blood
      draw. However, if a second visit occured, it took place within 40 days of the first visit.
allocation: N/A
intervention model: Single Group Assignment
primary purpose: Other
masking: None (Open Label)
measure: Number of Participants Who Provided Whole Blood Samples for DNA Extraction and Analysis
time frame: Baseline (Day 1)
description: Each participant provided a maximum total of 69 milliliter of whole blood sample. Samples were collected in the following order: 1. Deoxyribonucleic acid (DNA) Paired box (PAX)gene tubes (2 tubes), 2. Ribonucleic acid (RNA) PAXgene tubes (2 tubes), 3. Ethylenediaminetetraacetic acid (EDTA) tubes for peripheral blood mononuclear cells (PBMCs) (5 tubes), 4. Serum Separator tube (SST) (1 tube), and 5. Dipotassium Ethylenediaminetetraacetic acid (K2EDTA) tube (1 tube); where DNA PAXgene tubes were used for DNA preparation, RNA PAXgene tubes for RNA preparation, EDTA for PBMC isolation, SST tubes for serum preparation and K2EDTA for plasma preparation. DNA was extracted from peripheral blood for future analysis.
