21 November 2019
- Knight receives exclusive license to commercialize rigosertib in Canada
- Onconova eligible to receive up to CAD 33.95 million in clinical, regulatory, and sales-based milestones and tiered double-digit royalties
NEWTOWN, Pa., Nov. 21, 2019 (GLOBE NEWSWIRE) -- Onconova Therapeutics, Inc. (NASDAQ: ONTX) (“Onconova”), a Phase 3-stage biopharmaceutical company discovering and developing novel products to treat cancer, with a focus on myelodysplastic syndromes (MDS), today announced they have entered into a Distribution, License and Supply Agreement with Knight Therapeutics Inc. (“Knight”), a Canadian-based specialty pharmaceutical company focused on acquiring, in-licensing, selling and marketing innovative prescription and over-the-counter pharmaceutical products, whereby Knight shall have the exclusive rights to commercialize rigosertib in Canada. In addition, Onconova may be entitled to receive clinical, regulatory and sales-based milestone payments up to CAD 33.95 million and tiered double-digit royalties on net sales.
"We are pleased to add Knight to our roster of global partners for rigosertib," said Dr. Steven Fruchtman, President and Chief Executive Officer of Onconova. "We are eager to work with Knight’s team, which has successfully partnered with a number of biotechnology companies to commercialize innovative medicines in Canada.”
“Patients with high-risk MDS have limited treatment options after first-line hypomethylating agents such as azacitidine fail," said Jonathan Ross Goodman, Chief Executive Officer of Knight. "If approved, rigosertib would address this unmet need and we look forward to the results of the ongoing phase III INSPIRE trial of IV rigosertib."
About Myelodysplastic Syndromes
MDS is a group of blood disorders that affect bone marrow function, whereby the bone marrow cells appear dysplastic and their capacity to produce cells is defective. As a result, patients with MDS have low blood cell counts and require frequent blood transfusions. In approximately one-third of patients, higher-risk MDS can progress to acute myelogenous leukemia (AML).
The Leukemia and Lymphoma Society of Canada estimates that there are between 1,800 and 5,900 new cases of MDS diagnosed in Canada each year. MDS is typically diagnosed in older individuals, and most patients diagnosed with the disease are over the age of 60. Approximately 23% of cases can be classified as having high risk or very high risk MDS as per the revised International Prognostic Scoring System (IPSS-R)1.
Rigosertib, Onconova’s lead candidate, is a proprietary Phase 3 small molecule. A key publication in a preclinical model demonstrated rigosertib’s ability to block cellular signaling by targeting RAS effector pathways (Divakar, S.K., et al., 2016: "A Small Molecule RAS-Mimetic Disrupts RAS Association with Effector Proteins to Block Signaling." Cell 165, 643). Onconova is currently in the clinical development stage with oral and IV rigosertib, including clinical trials studying single agent IV rigosertib in second-line higher-risk MDS patients (pivotal Phase 3 INSPIRE trial) and oral rigosertib plus azacitidine in first-line and refractory higher-risk MDS patients (Phase 2). Patents covering oral and injectable rigosertib have been issued in the US and are expected to provide coverage until at least 2037.
About the INSPIRE Phase 3 Clinical Trial
The clinical trial INternational Study of Phase 3 IV RigosErtib, or INSPIRE, was finalized following guidance received from the U.S. Food and Drug Administration and European Medicines Agency. INSPIRE is a global, multi-center, randomized, controlled study to assess the efficacy and safety of IV rigosertib in higher-risk MDS (HR-MDS) patients who had progressed on, failed to respond to, or relapsed after previous treatment with a hypomethylating agent (HMA) within nine cycles over the course of one year after initiation of HMA treatment. This time frame optimizes the opportunity to respond to treatment with an HMA prior to declaring treatment failure, as per NCCN Guidelines. Patients are randomized at a 2:1 ratio into two study arms: IV rigosertib plus Best Supportive Care versus Physician's Choice plus Best Supportive Care. The primary endpoint of INSPIRE is overall survival. The trial continued beyond the pre-specified interim analysis and is nearing its conclusion. Full details of the INSPIRE trial, such as inclusion and exclusion criteria, as well as secondary endpoints, can be found on clinicaltrials.gov (NCT02562443).
