AG-013736 is an oral anti-angiogenesis agent with activity against a variety of receptor tyrosine kinases, including VEGFR-1, VEGFR-2, VEGFR-3, c-kit, and PDGFR-beta. A phase 2 study was conducted in patients with poor prognosis AML or MDS. Twelve patients (six AML; six MDS) were treated with AG-013736 at a dose of 10mg orally daily for a median of 56 days (range, 1-248 days). Median age was 80 years (range, 58-88 years). Grade 3 or 4 drug-related toxicities included hypertension (42%), mucositis (8%) and deep venous thrombosis (8%). No objective responses occurred; two patients with MDS had stable disease for 8.3 and 6.2 months, respectively. Bone marrow expression of VEGFR-1 and VEGFR-2 was observed in 11% and 0% of patients, respectively. Sustained decreases in soluble VEGFR-2 plasma levels with concomitant elevation in plasma VEGF and placental growth factor levels were obtained during the course of therapy with AG-013736. AG-01736 had minimal biologic or clinical activity in this elderly patient population.

We treated 95 RBC transfusion dependent lower risk MDS with del 5q with Lenalidomide (10mg/day, 3 weeks/4 weeks). Median age was 70.4, median interval from diagnosis 29 months. IPSS was low in 31% and intermediate-1 in 69% patients. Del 5q was isolated, with 1 additional and >1 additional abnormality in 79%, 14%, and 6% patients, respectively. 62 (65%) patients achieved transfusion independence (TI). The only significant factor predicting TI was baseline platelet count >150 G/L and platelet decrease by at least 50% during the first weeks of treatment (p=0.001). Grade III-IV neutropenia and thrombocytopenia were seen in 74% and 37.9% of the cases, respectively, and 3 deaths were attributed to cytopenias. Eight (8%) patients developed deep venous thrombosis (DVT). Platelet decrease by less than 50% predicted a higher risk of DVT. Only 6 patients (6.3%) patients progressed to AML, but median follow-up time was short (18 months). We confirm the high rate of TI with Lenalidomide in lower risk MDS with del 5q. Very close patient monitoring for cytopenias and DVT is mandatory, especially during the first weeks of treatment.
