“We are excited to host this important educational event on recent advances in the treatment of myelodysplastic syndromes and other RAS-mutated cancers, and honored that two prominent research leaders in their field, Dr. Lewis Silverman, a recognized expert in MDS, and Dr. Rajwanth Veluswamy, a prominent researcher and clinician in lung cancer, have agreed to speak,” said Steven M. Fruchtman, MD, President and Chief Executive Officer of Onconova. “In addition to the presentations by Drs. Silverman and Veluswamy, we will be discussing our Phase 2 oral rigosertib data, which were recently presented at the American Society of Hematology (ASH) annual meeting in December. We will also discuss future plans and near-term milestones, including pivotal Phase 3 data with IV rigosertib in high-risk MDS patients.”
Key findings from the Phase 2 trial data presented at ASH include:
- Overall response rate (ORR) of 90% reported in this multi-institutional Phase 2 study in hypomethylating agent (HMA) naïve patients, including Complete Remission (CR) rate of 34%
- Median duration of response for the HMA naïve patients was 12.2 months
- Acceptable safety profile when oral rigosertib is combined with the FDA-approved dose of azacitidine

About Onconova Therapeutics, Inc.
Onconova Therapeutics, Inc. is a Phase 3-stage biopharmaceutical company focused on discovering and developing novel small molecule drug candidates to treat cancer, with a primary focus on Myelodysplastic Syndromes (MDS). Rigosertib, Onconova's lead candidate, is a proprietary Phase 3 small molecule agent, which the Company believes blocks cellular signaling by targeting RAS effector pathways. Using a proprietary chemistry platform, Onconova has created a pipeline of targeted agents designed to work against specific cellular pathways that are important in cancer cells. Onconova has three product candidates in the clinical stage and several pre-clinical programs. Advanced clinical trials with the Company’s lead compound, rigosertib, are aimed at what the Company believes are unmet medical needs of patients with MDS.

About Rigosertib
Rigosertib is a small molecule that is reported to block cellular signaling by targeting RAS effector pathways (Divikar, 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 clinic with oral and IV rigosertib. This includes single agent IV rigosertib in 2nd line high-risk MDS patients (pivotal Phase 3 INSPIRE trial) and oral rigosertib plus azacitidine in 1st line high-risk MDS patients (Phase 2).
About IV Rigosertib
The intravenous form of rigosertib has been employed in Phase 1, 2, and 3 clinical trials involving more than 800 patients, and is currently being evaluated in a randomized Phase 3 international INSPIRE trial for patients with higher-risk MDS, after failure of hypomethylating agent, or HMA, therapy.
About the INSPIRE Phase 3 Clinical Trial
The 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 and derives from the findings of the ONTIME Phase 3 trial. INSPIRE is a multi-center, randomized controlled study to assess the efficacy and safety of IV rigosertib in HR-MDS patients who had progressed on, failed to respond to, or relapsed after previous treatment with an HMA within the first 9 months or 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. Following interim analysis in early 2018, the independent Data Monitoring Committee recommended that the trial continue with an expansion in enrollment to 360 patients based on a pre-planned sample size re-estimation. Patients are randomized at a 2:1 ratio into two treatment arms: IV rigosertib plus Best Supportive Care versus Physician's Choice plus Best Supportive Care. The primary endpoint of INSPIRE is overall survival. Full details of the INSPIRE trial, such as inclusion and exclusion criteria, as well as secondary endpoints, can be found on clinicaltrials.gov (NCT02562443).
About Oral Rigosertib
The oral form of rigosertib was developed to provide more convenient dosing for use where the duration of treatment may extend to multiple years. This dosage form may also support many combination therapy modalities. To date, 368 patients have been treated with the oral formulation of rigosertib. Initial studies with single-agent oral rigosertib were conducted in hematological malignancies, lower-risk MDS, and solid tumors. Combination therapy of oral rigosertib with azacitidine and chemoradiotherapy has also been explored. Currently, oral rigosertib is being developed as a combination therapy together with azacitidine for patients with higher-risk MDS who require HMA therapy. A Phase 1/2 trial of the combination therapy has been fully enrolled, and the preliminary results were presented in 2016. This novel combination is the subject of an issued U.S. patent with earliest expiration in 2028.
