Luspatercept Increases Hemoglobin and Reduces Transfusion Burden in Patients with Low-Intermediate Risk Myelodysplastic Syndromes (MDS): Long-Term Re…
2016
Abstract Background: Management of anemia is a common therapeutic challenge in patients with MDS. Luspatercept (ACE-536), a fusion protein containing modified activin receptor type IIB, is being developed for treatment of anemia in lower-risk MDS. Luspatercept binds GDF11 and other TGF-β superfamily ligands to promote late-stage erythroid differentiation and increase hemoglobin (Hgb) levels (Suragani R, Nat Med, 2014 and Attie K, Am J Hematol, 2014). Aims: This is an ongoing, phase 2, multicenter, open-label, long-term extension study to evaluate the effects of luspatercept in patients (pts) with low-intermediate risk MDS. Endpoints include long-term safety and tolerability, erythroid respo…

Biomarkers of Ineffective Erythropoiesis Predict Response to Luspatercept in Patients with Low or Intermediate-1 Risk Myelodysplastic Syndromes (MDS)…
2015
Abstract Background: Luspatercept is a fusion protein (modified activin receptor IIB-IgG Fc) being investigated for the treatment of anemias with ineffective erythropoiesis. MDS patients have increased Smad2/3 signaling in the bone marrow, leading to ineffective erythropoiesis. Luspatercept inhibits Smad2/3 signaling and promotes late-stage erythroid differentiation, thereby correcting ineffective erythropoiesis. Aims: This completed, 3-month, phase 2, multicenter, open-label study evaluated the effects of luspatercept on anemia in patients with low/int-1 risk MDS (IPSS classification). Study outcomes include erythroid response of increased hemoglobin (Hb) in low transfusion burden (LTB) pa…
Final report of the efficacy and safety of gemtuzumab ozogamicin (Mylotarg) in patients with CD33-positive acute myeloid leukemia in first recurrence
2005
BACKGROUND In this study, the authors analyzed the efficacy and safety of gemtuzumab ozogamicin (GO) (Mylotarg®), an antibody-targeted chemotherapy for CD33-positive acute myeloid leukemia (AML). METHODS Patients with CD33-positive AML in first recurrence were entered in 3 open-label, single-arm, Phase II studies. Patients received monotherapy with GO 9 mg/m2 as a 2-hour intravenous infusion in 2 doses separated by 2 weeks. Patients were evaluated for remission, survival, and treatment-emergent adverse events. RESULTS Two hundred seventy-seven patients (median age, 61 yrs) were treated with GO, and 71 patients (26%) achieved remission, which was defined as ≤ 5% blasts in the bone marrow wit…
53 LUSPATERCEPT INCREASES HEMOGLOBIN AND REDUCES TRANSFUSION BURDEN IN PATIENTS WITH LOW OR INTERMEDIATE-1 RISK MYELODYSPLASTIC SYNDROMES (MDS): PREL…
2015
Introduction. ACE-536, a recombinant fusion protein containing modified activin receptor type IIB and IgG Fc, is being developed for the treatment of anemias due to ineffective erythropoiesis, such as myelodysplastic syndromes (MDS). Patients with MDS often have elevated levels of erythropoietin (EPO) and may be non-responsive or refractory to erythropoiesis-stimulating agents (ESAs). MDS patients have also been shown to have increased serum GDF11 levels (Suragani R et al., Nature Medicine 2014) and increased Smad 2/3 signaling in the bone marrow (Zhou L et al., Blood 2008). ACE-536 binds to ligands in the TGF-s superfamily, including GDF11, inhibits Smad 2/3 signaling, and promotes late-st…

Background: Luspatercept is a fusion protein (modified activin receptor IIB-IgG Fc) being investigated for the treatment of anemias with ineffective erythropoiesis. MDS patients have increased Smad2/3 signaling in the bone marrow, leading to ineffective erythropoiesis. Luspatercept inhibits Smad2/3 signaling and promotes late-stage erythroid differentiation, thereby correcting the ineffective erythropoiesis. Aims: This is an ongoing, phase 2, multicenter, open-label, 24-month extension study (following a 3-month base study) to evaluate the longer-term effects of luspatercept on anemia in patients (pts) with low/int-1 risk MDS (IPSS classification). Study outcomes include erythroid response…

Luspatercept for the treatment of anaemia in patients with lower-risk myelodysplastic syndromes (PACE-MDS): a multicentre, open-label phase 2 dose-fi…
2017
Myelodysplastic syndromes are characterised by ineffective erythropoiesis. Luspatercept (ACE-536) is a novel fusion protein that blocks transforming growth factor beta (TGF β) superfamily inhibitors of erythropoiesis, giving rise to a promising new investigative therapy. We aimed to assess the safety and efficacy of luspatercept in patients with anaemia due to lower-risk myelodysplastic syndromes.In this phase 2, multicentre, open-label, dose-finding study (PACE-MDS), with long-term extension, eligible patients were aged 18 years or older, had International Prognostic Scoring System-defined low or intermediate 1 risk myelodysplastic syndromes or non-proliferative chronic myelomonocytic leuk…
