We combined reduced-intensity conditioning and 188rhenium anti-CD66 radioimmunotherapy in a prospective phase II trial.
Associated with limited extramedullary toxicity in 58 patients with high-risk acute myeloid leukemia/myelodysplastic syndrome.
Reduction of Campath-1H from 75 to 50 mg did not improve overall outcome.
Further optimization of the current approach is needed.
