Maximum Tolerated Dose of Ruxolitinib Phosphate (Phase I) Primary · Up to 6 weeks

Maximum tolerated dose (MTD) is defined as the highest dose studied for which the incidence of dose-limiting toxicity (DLT) is less than or equal to 17% (1 out of 6).

Sponsor's own description

This phase I/II trial studies the side effects and best dose of ruxolitinib phosphate when given together with decitabine and to see how well they work in treating patients with acute myeloid leukemia that has come back or is not responding to treatment, or has developed from a type of bone marrow diseases called myeloproliferative neoplasms. Ruxolitinib phosphate may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as decitabine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving ruxolitinib phosphate together with decitabine may be an effective treatment for acute myeloid leukemia.
