​

We are a biotechnology company dedicated to discovering, developing and providing novel small molecule drugs that significantly improve the lives of patients with immune and hematologic disorders, cancer and rare diseases. Our pioneering research focuses on signaling pathways that are critical to disease mechanisms. Our first product approved by the United States Food and Drug Administration (FDA) is TAVALISSE^® (fostamatinib disodium hexahydrate) tablets, the only oral spleen tyrosine kinase (SYK) inhibitor, for the treatment of adult patients with chronic immune thrombocytopenia (ITP) who have had an insufficient response to a previous treatment. The product has been approved by the European Commission (EC) for the treatment of chronic ITP in adult patients who are refractory to other treatments and is marketed in Europe under the name TAVLESSE^® (fostamatinib). Fostamatinib is currently being studied in a Phase 3 trial for the treatment of warm autoimmune hemolytic anemia (AIHA); a NIH/NHLBI-Sponsored Phase 2 trial for the treatment of hospitalized COVID-19 patients, in collaboration with Inova^® Health System; and a Phase 2 trial for the treatment of COVID-19 pneumonia being conducted by Imperial College London. Additionally, we plan to study fostamatinib in a Phase 3 clinical trial for the treatment of hospitalized COVID-19 patients which is expected to launch in the fourth quarter of 2020. Other clinical trials include an ongoing Phase 1 study of R835, a proprietary molecule from its interleukin receptor associated kinase (IRAK) inhibitor program; and an ongoing Phase 1 study of R552, a proprietary molecule from its receptor-interacting protein kinase (RIP) inhibitor program. In addition, we have product candidates in clinical development with partners AstraZeneca (AZ), BerGenBio ASA (BerGenBio), and Daiichi Sankyo (Daiichi).
