Summary

The lay summary the sponsor registered on ClinicalTrials.gov.

This phase I trial tests the safety, side effects and best dose of lintuzumab-Ac225 for the treatment of patients with high risk myelodysplastic syndrome that has not responded to previous treatment (refractory). Lintuzumab-Ac225 is a monoclonal antibody, called lintuzumab, linked to a radioactive agent called Ac225. Lintuzumab attaches to CD33 positive cancer cells in a targeted way and delivers Ac225 to kill them. Giving lintuzumab-Ac225 may be safe, tolerable and/or effective in treating patients with high risk, refractory myelodysplastic syndrome.
