In the former case, tailored inhibitors of MIF that are already in the clinical setting could be considered for pilot studies, which include the tautomerase inhibitor ibudilast that is marketed for different indications and is being repurposed for immunoinflammatory diseases [70], as well as anti-MIF mAb that have completed Phase I/II testing in cancer patients and the anti-CD74 mAb milatuzumab that is approved for patients with multiple myeloma [71]. Here, MIF is linked to plasma cell myeloma.
