<b>Methods</b>: Sixty patients with MS and a suboptimal response to IFN-β were randomized (1:1) into two groups: the IFN-CUR group, which received add-on therapy with micellar curcumin (containing curcumin and Tween 80 as a solubilizer) for 6 months, and a control group (IFN group), which received IFN-β alone. Here, IFNA1 is linked to myeloid sarcoma.
