Last verified: October 2011
This study is a phase I, open-label, single-arm, dose escalation trial to determine the safety and activity of lenalidomide combined with lintuzumab in patients with MDS. Small groups of 3-6 patients will be treated with pre-specified doses of lenalidomide and lintuzumab and will receive 3-week cycles of combination therapy.

Myelodysplastic Syndrome (MDS) Drug: lintuzumab Drug: lenalidomide Phase 1

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Phase I Combination Trial of SGN-33 (Anti-huCD33 mAb; HuM195; Lintuzumab) and Lenalidomide (Revlimid®) in Patients With Myelodysplastic Syndromes (MDS)
