Relapsed or Refractory Myelodysplastic Syndromes

Current Clinical Trials

Lack of response or progression after the use of erythropoiesis-stimulating agents is not considered relapsed or refractory myelodysplastic syndromes (MDS).

With the exception of the use of lenalidomide for low-risk patients with abnormalities of chromosome 5, there are no clinical trials informing the appropriate selection of current therapies for patients with specific subtypes of MDS. Patients who have ceased to respond or did not respond to one therapy are frequently offered another from the therapies described in the previous sections. Retrospective data suggest that patients who do not respond or have ceased responding to DNA methyltransferase inhibitors have a median survival of only 4 to 6 months.[1,2] Relapsed patients should be considered for enrollment in clinical trials.

Current Clinical Trials

Check for U.S. clinical trials from NCI's list of cancer clinical trials that are now accepting patients with adult myelodysplastic syndromes. The list of clinical trials can be further narrowed by location, drug, intervention, and other criteria.

General information about clinical trials is also available from the NCI Web site.
