Onconova Therapeutics Announces Completion of Enrollment of Phase 3 INSPIRE Trial, Provides a Corporate Update, and Reports 2019 Financial Results
NEWTOWN, Pa., March 24, 2020 (GLOBE NEWSWIRE) -- Onconova Therapeutics, Inc. (NASDAQ: ONTX), a Phase 3 stage biopharmaceutical company focused on discovering and developing novel products to treat cancer, with an initial focus on myelodysplastic syndromes (MDS), today reported financial results for the year ended December 31, 2019 and provided a corporate update.
“Following significant progress throughout 2019, our team’s immediate focus remains to advance our pivotal Phase 3 INSPIRE trial to the next milestone,” said Steven M. Fruchtman, M.D., President and Chief Executive Officer. “We are excited to announce the completion of the planned enrollment of 360 patients in the INSPIRE trial in higher-risk (HR) MDS patients. INSPIRE represents one of the largest studies ever conducted in this patient population. Based on survival trends on the INSPIRE trial to date, we anticipate reporting topline survival data in the second half of 2020 and presenting the results at a medical meeting later this year. We continue to analyze deep genomic sequencing, including mutations of the Ras pathway, on these patients. Important genomic results were presented at ASH 2019 and additional data is expected to be presented at future medical meetings.”
Dr. Selina Luger, M.D., Professor of Medicine at the Hospital of the University of Pennsylvania Division of Hematology Oncology, commented, “in second line HR MDS, following progression or failure of patients to respond to hypomethylating agents, there is no standard of care and currently no health authority approved agent in the world. There is a tremendous unmet medical need for these patients. The INSPIRE trial, which has now reached full accrual, is studying the experimental agent rigosertib to determine if it can significantly prolong the survival of these patients when compared to physician’s choice of therapy. We eagerly look forward to the results of this pivotal trial.”
Dr. Fruchtman continued, “We are also pleased about the progress of our plans for additional investigator-initiated studies – including the Phase 1/2a study of rigosertib plus nivolumab for the treatment of Stage IV KRAS mutated lung adenocarcinoma. We anticipate the first patient to be entered onto the trial once the COVID-19 environment improves sufficiently.”

Full Year 2019 Financial Results
Cash and cash equivalents as of December 31, 2019, totaled $22.7 million, compared to $17.0 million as of December 31, 2018. Besides the $9 million of net proceeds from the financing closed in early 2020, common stock warrant exercises since 12/31/19 have added $5.7 million to the Company’s cash balance resulting in a cash balance at February 29, 2020 of $32.6 million. Based on current projections, the Company expects that cash and cash equivalents will be sufficient to fund ongoing trials and operations into the third quarter of 2021.
Net loss was $21.5 million for the year ended December 31, 2019, compared to $20.4 million for the year ended December 31, 2018. Research and development expenses were $15.5 million for the year ended December 31, 2019 and $16.9 million for the comparable period in 2018. General and administrative expenses were $8.3 million for the year ended December 31, 2019 and $7.6 million for the comparable period in 2018.

About Myelodysplastic Syndromes
Myelodysplastic syndromes (MDS) are conditions that can occur when the blood-forming cells in the bone marrow become dysfunctional and thus produce an inadequate number of circulating blood cells. It is frequently associated with the presence of blasts or leukemic cells in the marrow. This leads to low numbers of one or more types of circulating blood cells, and to the need for blood transfusions. In MDS, some of the cells in the bone marrow are abnormal (dysplastic) and may have genetic abnormalities associated with them. Different cell types can be affected, although the most common finding in MDS is a shortage of red blood cells (anemia). Patients with higher-risk MDS may progress to the development of acute leukemia.
About Rigosertib
Rigosertib, Onconova’s lead candidate, is a proprietary Phase 3 small molecule. A key publication in a preclinical model reported 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 HMA naive 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).
About IV Rigosertib
The intravenous form of rigosertib has been studied in Phase 1, 2, and 3 clinical trials involving more than 1000 patients, and is currently being evaluated in a randomized Phase 3 international INSPIRE trial for patients with HR-MDS after failure of HMA therapy.
About Oral Rigosertib
The oral form of rigosertib was developed to provide a potentially more convenient dosage form for use where the duration of treatment may extend to multiple years. This dosage form may also support combination therapy modalities. To date, over 400 patients have been dosed with the oral formulation of rigosertib in clinical trials. Combination therapy of oral rigosertib with azacitidine, the standard of care in HR-MDS, has also been studied. 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 updated efficacy and safety data was presented at the ASH 2019 Annual Meeting in December 2019.
