Medicine Matters oncology

Cobomarsen is a miR-155 inhibitor that has recently emerged as a novel candidate for systemic CTCL therapy. It has been found that STAT5 drives expression of oncogenic BIC/miR-155 in cancer, and the STAT5/BIC/miR-155 pathway has been shown to promote proliferation of malignant T cells [24]. Therefore, inhibition of miR-155 is thought to be a good target for CTCL treatment. A phase I study of MRG-106 is currently underway and preliminary results showed that 26 out of 29 evaluable subjects had improvement in mSWAT scores, suggesting that MRG-106 is well tolerated, has clinical activity, and may improve quality of life in MF [25].
