- To assess the rate and amount of supportive care, including transfusions and myeloid growth factors
- To evaluate the pharmacokinetics and immunogenicity of imetelstat in subjects with MDS
- To assess the effect of imetelstat treatment on patient reported outcomes (PROs)
- To assess the effect of treatment on medical resource utilization |
