ABSTRACT:
Stable therapeutic radionuclide compositions comprising, for example, .sup.186 Re, .sup.188 Re and .sup.131 I stably bound to a proteinaceous targeting moiety and suitable for human in vivo administration are disclosed. Stabilizing agents preferably comprise antioxidants and challenging agents, and combination of HSA with an antioxidant and/or challenging agent provides enhanced long term stability. Ascorbic acid is an especially preferred stabilizing agent, which provides stability of therapeutic radionuclide compositions at levels of at least about 90% for several hours up to several days.
