Hi George,
You know both Nplate and Promacta/Revolade are approved but have restrictions so only patients with Immune Thrombocytopenic Purpura can get the drugs so far.
The FDA has a special warning about Nplate in MDS patients because the drug can make you disease worse (page 12)

Promacta/Eltrombopag seems to decrease leukemia cells in tubes. A new drug LGD 4665 should be in trials for MDS and many other drugs for low platelets are in pipelines
.
Kind regards
