| Inclusion Criteria: | 1) Patients with MDS with >/= 5% blasts or IPSS risk group intermediate (1 or 2) or high (i.e., IPSS score 0.5 or higher).
2) Patients must have failed prior therapy with either chemotherapy (e.g., ara-C-based chemotherapy, etc) or biologic agents (e.g., hypomaethylating agents, arsenic, thalidomide, CC5013, farnesyl transferase inhibitors, ATG, cyclosporine, etc).
3) Age >/= 18 years. Because no dosing or adverse event data are currently available on the use of Gimatecan in patients <18 years of age, children are excluded from this study but will be eligible for future pediatric single-agent trials, if applicable.
4) ECOG performance status 0-2.
5) Patients must have normal organ function as defined below: 1) Total bilirubin: </= 1.5 x institutional upper limit of normal; 2) ALT(SGPT): </= 2.5 x institutional upper limit of normal; 3) Creatinine: </= 1.5 x institutional upper limit of normal.
6) The effects of Gimatecan on the developing human fetus at the recommended therapeutic dose are unknown. For this reason women of child-bearing potential (ie, not post-menopausal for at least 12 months and not surgically sterile) and men must agree to use double-barrier contraception prior to study entry, for the duration of study participation, and for 3 months following discontinuation of study treatment. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately.
