Antibody Comments
An anti-ERBB2/CD3e Triomab® called ertumaxomab (Rexomun®) has demonstrated antitumour efficacy against HER2/neu low-expressing breast tumours that are resistant to trastuzumab [18]. Development of ertumaxomab was not progressed beyond Phase 2 for business reasons. No safety issues had been apparent. See the entry for catumaxomab for full details of Triomab® mechanism of action.
Dragonfly Therapeutics are developing agents, using a platform called TriNKETTM (an abbreviation for tri-specific natural killer cell engagement therapies), that simultaneously engage a surface protein on target cells (e.g. cancer cells) and an as yet undisclosed natural killer (NK) cell protein so as to activate and redirect NK cells of the innate and adaptive immune system to destroy cancers. A patent held by Dragonfly Therapeutics suggests that one of the NK cell targets they are interested in is NKG2D (KLRK1; P26718) [7]. Their most advanced candidate (as of November 2019) is DF1001, a HER2-targeting TriNKETTM that has begun Phase 1/2 evaluation in HER2 +ve solid tumours (see NCT04143711). TriNKETTM therapeutics have the potential to treat autoimmune disease in addition to cancer.
