Apogenix's asunercept receives European orphan designation to treat myelodysplastic syndromes

Apogenix AG, a biopharmaceutical company developing next-generation immuno-oncology therapeutics, announced that its lead product candidate, asunercept (APG101), has been granted orphan designation from the European Commission (EC) for the treatment of myelodysplastic syndromes (MDS). MDS is a bone marrow disorder characterized by ineffective hematopoiesis (blood cell formation) and can lead to severe anemia. Patients often suffer from life-threatening infections and are at risk of developing acute myeloid leukaemia.

Orphan designation includes access to a centralized marketing authorization procedure for the European Union, ten years of protection from market competition with similar medicines in similar indications and fee reductions for consultations with the EMA. Earlier, asunercept received Orphan Drug Designation for MDS from the US Food and Drug Administration (FDA).

Dr. Harald Fricke, chief medical officer of Apogenix, commented: "The vast majority of patients suffering from MDS are anemic and dependent on frequent regular blood transfusions. Asunercept prevents premature death of red blood cells in the bone marrow and thus reduces the need of blood transfusions, even making them superfluous in many patients. We are highly encouraged by the data from our clinical phase I trial with asunercept in these patients and are currently preparing to initiate a clinical phase II proof-of-concept trial to further evaluate the efficacy of asunercept in MDS."

Asunercept has been evaluated in an open label, single-arm phase I clinical trial in 20 patients with low to intermediate risk MDS, in which treatment with asunercept was well tolerated and led to a significant decrease in transfusion frequency. In addition, investigation of parameters involved in erythropoiesis delineated how asunercept stimulates the production of red blood cells in these patients.

Asunercept binds to the CD95 ligand (CD95L) and blocks the activation of the CD95 receptor. Excessive stimulation of the CD95 receptor on hematopoietic precursor cells in the bone marrow of MDS patients inhibits erythropoiesis. As a result, transfusion-dependent anemia develops, which is refractory to erythropoiesis-stimulating agents. Treatment with asunercept, which inhibits the CD95 system, addresses this major cause of the disorder.
