We developed a highly stable rhenium-186 ($$^{186}$$Re)-MAG3 complex-conjugated bisphosphonate, ($$^{186}$$Re-MAG3-HBP), for the treatment of painful bone metastases. This agent showed a superior biodistribution as a bone-seeking agent in normal mice when compared with $$^{186}$$Re-HEDP. In this study, we evaluated the therapeutic effects of $$^{186}$$Re-MAG3-HBP using an animal model of bone metastasis. In the rats treated with $$^{186}$$Re-HEDP, tumor growth was comparable to that in untreated rats. In contrast, when $$^{186}$$Re-MAG3-HBP was administered, tumor growth was significantly inhibited. Allodynia induced by bone metastasis was attenuated by treatment with $$^{186}$$Re-MAG3-HBP or $$^{186}$$Re-HEDP, but $$^{186}$$Re-MAG3-HBP tended to be more effective. These results indicate that $$^{186}$$Re-MAG3-HBP could be useful as a therapeutic agent for the palliation of metastatic bone pain.
