A Phase II Study of an Oral VEGF Receptor Tyrosine Kinase Inhibitor (PTK787/ZK222584) (IND #66370, NSC #719335) in Myelodysplastic Syndrome (MDS)

Time to Transformation to AML

时间窗: Duration of study (up to 5 years)

Time to transformation to AML is defined as the time from registration to the transformation of MDS to AML or death of any cause. Participants not meeting these criteria were censored at the date of last follow-up. This outcome was estimated using the Kaplan Meier method.

Number of Participants With Response

时间窗: Duration of study (up to 5 years)

Response was measured by International Standardized Response Criteria for MDS * Complete Response: Bone marrow showing \< 5% myeloblasts with normal maturation of all cell lines; Hgb \> 11 g/dL (untransfused), ANC ≥1.5 K/L, PLT ≥ 100 K/L, No blasts, no dysplasia * Partial remission: All of the CR criteria (if abnormal at baseline), except BM evaluation. Blasts decreased by ≥ 50% over baseline. Cellularity and morphology are not relevant. Hematologic improvement: * Erythroid (HI-E): For participants with baseline HGB \< 11g/dL, Major: \> 2g/dL increase, transfusion independence. Minor: 1-2g/dL increase, ≥ 50% decrease in transfusion requirements * Platelet (HI-P): For participants with baseline PLT \< 100 K/L: Major: absolute increase of \> 30 K/L, transfusion independence. Minor: ≥ 50% increase (net increase of \>10 K/L) * Neutrophil (HI-N): For participants with baseline ANC \< 1.5 K/L, Major: \> 100% increase (net increase \> 0.5 K/L). Minor: \> 100% increase (absolute increase \< 0.5 K/L)
