''We look forward to working closely with Baxter with the shared goal of providing this therapy to patients in Europe,'' said Ramesh Kumar, Chief Executive Officer of Onconova. ''The financial resources resulting from this transaction will help to advance the rigosertib program toward commmercialization and will support other Onconova candidates in clinical development including Ex-RAD ®, a radioprotectant, and ON 013105, our second novel anti-cancer agent.''
Rigosertib’s mechanism of action targets dual pathways (PI-3K and PLK) critical to the growth of cancer cells. It has been studied in more than 600 patients worldwide and has shown activity in treating both solid tumors and hematological malignancies. Rigosertib is currently being evaluated in a Phase III clinical trial in 270 MDS patients who have failed or relapsed after receiving current therapeutic options, with initial results expected in the second half of 2013. Rigosertib is also in a Phase II/III combination study in patients with previously untreated metastatic pancreatic cancer. In addition, an oral formulation of rigosertib is in a Phase II study in transfusion-dependent low or intermediate-1 risk MDS patients. Onconova has gained orphan drug designation for MDS in the United States and Europe.
MDS includes a wide range of bone marrow disorders, each associated with increased risk of bleeding and infection, and an increased risk of progression to acute myeloid leukemia (AML). MDS patients often require multiple blood transfusions and extensive supportive care to manage their disease, with very poor survival rates. 1 The annual incidence of MDS in Europe is approximately 3 per 100,000 people, and while MDS can occur in people of all ages, it is diagnosed most frequently in adults over 60 years of age. 2 Pancreatic cancer is a highly aggressive form of cancer. Because symptoms are vague, the disease is difficult to diagnose early and is associated with low survival rates. Recent figures suggest the mortality rate associated with pancreatic cancer in Europe is rising, and ranges between approximately 8/100,000 in men and 5/100,000 in women. 3
