In analogy with TTK, the cancer testis antigen MPHOSPH1 is being targeted as part of multi-peptide vaccinations to treat metastatic breast cancer (NCT01259505), bladder cancer (NCT00633204, NCT00635336), unresectable recurrent and/or metastatic solid tumors (NCT04316689), and cervical, gastro-intestinal and lung tumors (NCT00676949); however, no data has been published as yet. Here, KIF20B is linked to urinary bladder carcinoma.
