Embodiment 2

[0394] 8.2 Example 2: A phase 3 double-blind randomized placebo-controlled multicenter study to determine the efficacy and safety of ACTRIIB-HFC (SEQ ID NO: 25) in adults with transfusion-independent beta thalassemia

[0395] This example provides an overview of a phase 3 double-blind randomized placebo-controlled multicenter study to determine the efficacy and safety of ACTRIIB-HFC (SEQ ID NO: 25) in adults with transfusion-independent beta thalassemia. The indications for the phase 3 study are adults with transfusion-independent beta thalassemia, who are diagnosed with β-thalassemia or hemoglobin E / β-thalassemia.

[0396] 8.2.1 Goal

[0397] The main goal of the Phase 3 study is to determine if ActRIIB-hFc (SEQ ID NO: 25) is diagnosed as transfusion-independent β-thalassemia, documented β-thalassemia or hemoglobin E / β-thalassemia diagnosis, age ≥18 Years old and have received 0-6 red blood cell units and average baseline hemoglobin level within 24 weeks prior to random assignment ...

Embodiment 3

[0423] 8.3 Example 3: ACTRIIB-HFC (SEQ ID NO: 25) signal transduction inhibitor increases hemoglobin and reduces the burden of blood transfusion and reduces liver iron concentration in adults with β thalassemia

[0424] 8.3.1 Introduction

[0425] ActRIIB-hFc (SEQ ID NO: 25), a fusion protein containing a modified activin receptor, is being developed for the treatment of β-thalassemia. In β-thalassemia, anemia and complications are caused by ineffective erythropoiesis driven by excess α-globin. ActRIIB-hFc (SEQ ID NO: 25) binds to other ligands in the GDF11 and TGF-β superfamily to promote late red blood cell differentiation. Non-clinical and clinical studies have shown that ActRIIB-hFc (SEQ ID NO: 25) has a well-tolerated and corrective effect on ineffective erythropoiesis (Suragani R, Blood 2014, Attie K, Am JHematol 2014).

[0426] This example provides data from an ongoing Phase 2 multicenter open-label dose exploration study to evaluate ActRIIB-hFc (SEQ ID NO: 25) in adults wi...
