MIROCALS: Modifying Immune Response and OutComes in ALS

NCT03039673 · Status: COMPLETED · Phase: PHASE2 · Type: INTERVENTIONAL · Enrollment: 304

Summary

MIROCALS is a phase II study of ld-IL-2 as a therapeutic agent for ALS. A randomized (1:1), placebo-controlled, double-blind, parallel group trial will be carried out to assess ld-IL-2 safety and clinical efficacy on survival and functional decline in newly diagnosed ALS patients treated for 18 months. Randomization will be stratified according to (i) country (n = 2 levels: UK, France) and (ii) site of onset (n= 2 levels: bulbar vs limb onset).

The primary objective to evaluate the clinical efficacy and safety of the experimental drug (ld IL-2) over an 18 months period in order to establish the proof of concept (PoC) that modifying immune responses through the enhancement of regulatory T cells modifies the rate of ALS disease progression.

Conditions

Interventions

DRUG

Riluzole

All patients will be treated with Riluzole for a period of three months prior to final inclusion and randomization. Riluzole treatment will continue throughout the 18 months of follow-up planned for in this protocol. Riluzole treatment is part of routine care for patients with ALS.

DRUG

IL-2

The dose of IL-2 to be used in this study will be 2.0 million IU/day. Each treatment course will last 5 days (i.e. 1 sub-cutaneous injection per day for 5 consecutive days). The 5-day course will be repeated every 4-weeks over an 18-month treatment period. In case of intolerance, a flexible dose-reduction schedule is available.

DRUG

5% glucose water solution

The placebo consists of 5% glucose water solution, which is the matrix with which low-dose IL-2 injections are prepared in the experimental arm. Placebo injections are prepared in exactly the same manner as IL-2 injections, just without the IL-2. Each treatment course will last 5 days (i.e. 1 sub-cutaneous injection per day for 5 consecutive days). The 5-day course will be repeated every 4-weeks over an 18-month treatment period.
