NCT02424396

Brief Summary

Interleukin-2 (IL-2) was initially discovered and used as a stimulator of effector T lymphocytes (Teffs), but is now viewed as a very promising immunoregulatory drug having the capacity to stimulate regulatory T cells (Tregs). At low dose, Il-2 tips the Treg/Teff balance towards Tregs. Recently, it has been shown that Tregs of MS patients have reduced proliferative potential. MS-IL2 will assess the safety and biological efficacy of low-dose IL2 as a Treg inducer in a Relapsing-Remitting Multiple Sclerosis (RRMS), with the aim to stimulate Treg and define potential clinical benefits

Outcome Measures

Primary Outcomes (1)

  • Treg response to low dose IL2 induction course period, expressed as % of total CD4 cells

    at day5

Secondary Outcomes (8)

  • Change in Treg percentage on D15 after induction (D1-D5) compared to baseline

    at day15

  • Change in Treg percentage from D15 to M6 compared to baseline

    Day 15 to Day 169

  • The cumulative number of new lesions enhanced by Gd+ (Sum of Gd + lesions on T1 MRI on M2, M4 and M6)

    Day 57, Day 113 and Day 169

  • Frequency of patients free of Gd+ lesions at M6

    Day 169

  • The cumulative number of new T2 lesions

    Day 169

  • +3 more secondary outcomes
