This is an open label, multicenter Phase 1 dose escalation study evaluating five doses of ezatiostat in combination with lenalidomide in patients with non-del(5q) low to intermediate 1 risk MDS. The HI-E, HI-N, HI-P rates [by International Working Group (IWG) 2006 criteria] and safety of each treatment group will be evaluated to select the optimal dose of ezatiostat in combination with lenalidomide for future studies.

Primary Outcome Measures:
  • To establish the maximum tolerated dose (MTD) of ezatiostat in combination with lenalidomide [ Time Frame: 2 years ] [ Designated as safety issue: No ]
  • To determine the safety of ezatiostat in combination with lenalidomide [ Time Frame: 2 years ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
