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

Condition or disease Intervention/treatment Phase
Relapsing Remitting Multiple Sclerosis Drug: IL2 Drug: Placebo Phase 2

Detailed Description:

In MS-IL2, 30 RRMS patients will be treated in a randomized, double-blind, placebo controlled clinical trial. IL-2 will be administered first as an induction course of IL-2 or placebo each day for 5 days, followed by a maintenance course at the same dose or placebo every two weeks over 6 months.

The primary efficacy criteria will be the % change from baseline in Treg at day-5, which is indicative of the biological response to IL-2.

The secondary efficacy criteria will be (i) the maintenance of regulatory T cells during the 6 months of treatment with IL-2 vs. placebo and (ii) the stabilization or regression of the disease as determined by disease activity parameters assessed by MRI (cumulative number of new lesions in T1 enhanced by gadolinium after 6 months) in the groups treated with IL-2 compared to placebo.

Expected impact: MS-IL2 will define which patient respond to IL2 and which doses prevent relapses in RRMS. In addition, the deep phenomics studies will further provide the foundation for a clinical phase II to define clinical efficacy.

Primary Outcome Measures :
  1. Treg response to low dose IL2 induction course period, expressed as % of total CD4 cells [ Time Frame: at day5 ]

Secondary Outcome Measures :
  1. Change in Treg percentage on D15 after induction (D1-D5) compared to baseline [ Time Frame: at day15 ]
  2. Change in Treg percentage from D15 to M6 compared to baseline [ Time Frame: Day 15 to Day 169 ]
  3. The cumulative number of new lesions enhanced by Gd+ (Sum of Gd + lesions on T1 MRI on M2, M4 and M6) [ Time Frame: Day 57, Day 113 and Day 169 ]
  4. Frequency of patients free of Gd+ lesions at M6 [ Time Frame: Day 169 ]
  5. The cumulative number of new T2 lesions [ Time Frame: Day 169 ]
  6. Annual relapse rate (number of relapses observed over a 6 month period) [ Time Frame: Day 169 ]
  7. % of patients with flare [ Time Frame: Day 169 ]
  8. % of disease free patient i.e % of patient with no clinical symptoms and no activity on MRI [ Time Frame: Day 169 ]
