CAMBRIDGE, MA, USA I January 19, 2021 I Sumitomo Dainippon Pharma Oncology, Inc., a developer of novel cancer therapeutics, today announced that the first patient has been dosed in a Phase 1/2 study evaluating the investigational agent TP-0184, an activin receptor-like kinase 2 (ALK2) and ALK5 inhibitor, for the treatment of anemia in adult patients with low or intermediate risk myelodysplastic syndromes (MDS).
"The management of anemia in patients with MDS is challenging as this patient population tends to be older and often have non-hematological comorbidities which can make them relatively intolerant to therapy," said Patricia S. Andrews, Chief Executive Officer and Global Head of Oncology, Sumitomo Dainippon Pharma Oncology (SDP Oncology). "Given the high unmet medical need, we are looking forward to learning more about the potential of TP-0184 in this patient population."
The primary objectives of the Phase 1 part of the open-label, dose-escalation study are to assess the safety and tolerability of oral TP-0184 as well as determine the maximum tolerated dose (MTD) or maximum administered dose (MAD), and recommended dose for future expansion arms in the Phase 2 part of the study.
Following the completion of the Phase 1 portion of the study, the study will move into a Phase 2 expansion. The primary objectives of the Phase 2 portion of the study are to determine the effect of TP-0184 on the treatment of anemia in terms of hemoglobin increase, reduction in red blood cell transfusions and being red blood cell transfusion-free for at least eight weeks.
The trial is being conducted at sites in the United States. Additional information on this trial, including comprehensive inclusion and exclusion criteria, can be accessed at www.ClinicalTrials.gov (NCT04623996).
TP-0184 is an activin receptor-like kinase 2 (ALK2) and ALK5 inhibitor. ALK2, also known as activin A receptor type 1 (ACVR1), is mutated in multiple types of cancers, including diffuse intrinsic pontine glioma (DIPG), a malignancy with high morbidity and mortality affecting the pediatric population.1,2,3 ALK2 is also involved in regulation of iron homeostasis, through stabilization of hepcidin and reduction of bioavailable iron, which is associated with anemia of chronic disease.1,4 TP-0184 also has activity against ALK5, a transforming growth factor beta (TGFβ) family member that is involved in myelodysplastic syndrome (MDS). TP-0184 is currently being evaluated in a Phase 1 clinical trial in advanced solid tumors (NCT03429218) and in a Phase 1/2 clinical trial in treatment of anemia associated with myelodysplastic syndromes (MDS) (NCT04623996).
