Onconova Therapeutics, Inc. Reports Business Highlights and Second Quarter 2019 Financial Results

By GlobeNewswire,  August 14, 2019, 07:30:00 AM EDT


NEWTOWN, Pa., Aug. 14, 2019 (GLOBE NEWSWIRE) -- Onconova Therapeutics, Inc. (NASDAQ:ONTX), a Phase 3 stage biopharmaceutical company discovering and developing novel products to treat cancer, with a focus on Myelodysplastic Syndromes (MDS), today provided a corporate update and reported financial results for the second quarter ended June 30, 2019.

Steven M. Fruchtman, M.D., President and Chief Executive Officer, stated, "Enrollment in our global Phase 3 INSPIRE Trial with IV rigosertib in second-line, higher-risk MDS patients is progressing.  Our goal is to complete enrollment by the end of 2019 and we anticipate reporting top-line data in the first half of 2020 following full enrollment and 288 death events.  If the INSPIRE Trial is successful, we believe rigosertib could be the first new treatment for higher-risk MDS in more than 15 years, and based on its unique mechanism of action, has the potential to provide clinical benefit in other Ras mutated cancers."

Dr. Fruchtman continued, "In addition to advancing the INSPIRE Trial, our Special Protocol Assessment (SPA) request to the FDA for a Phase 3 combination trial of oral rigosertib plus azacitidine in first-line higher-risk MDS patients is being pursued.  We also have plans to target cancers driven by mutated Ras genes.  Ras-mutated cancers represent about a third of all human cancers, and a Phase 1 study of rigosertib in combination with a PD-1 inhibitor for patients with progressive K-Ras mutated non-small cell lung cancer is expected to commence in 2019 as an investigator-initiated study.  We are also working toward filing an IND for a Phase 1 trial of ON 123300, our investigational, first-in-class, dual inhibitor of CDK4/6 + ARK5, which we believe has the potential to treat various cancers including refractory metastatic breast cancer."

Second Quarter 2019 and Recent Highlights

  • On March 25, the Company announced that it had passed the 75 percent enrollment mark in the Phase 3 INSPIRE Trial.  Onconova remains focused on our primary goal of completing enrollment by the end of 2019 and expects to report top-line survival data following full enrollment and 288 death events.



    • More than 140 trial sites in 24 countries across four continents are open, including 21 sites in Japan.  The Company opened new clinical trial sites in already participating countries.  Additional geographies, including Brazil, are being opened during the coming months to add approximately 25 more sites.  This strategy is designed to support the goal of achieving full accrual to the INSPIRE Trial in 2019.  The Company anticipates reporting top-line data in the first half of 2020 following full enrollment and 288 death events.
  • The Company entered into a license agreement with HanX Biopharmaceuticals (HanX) for the development and commercialization of rigosertib in Greater China.  The agreement provides for $4 million of upfront payments to Onconova, including a $2 million cash upfront fee and an investment totaling $2 million in shares purchased at a premium to market.  In addition, HanX agreed to place $2 million in escrow in local currency for rigosertib clinical development expenses in Greater China. HanX will make additional regulatory, developmental, and sales-based milestone payments to Onconova of up to $45.5 million and will pay Onconova tiered royalties up to double digits on net sales in Greater China.  If approval is received, Onconova will supply rigosertib to HanX for development and commercialization.  HanX also will support Onconova's other clinical trial initiatives in Greater China.             
  • Onconova and Mission Bio have entered into a collaboration to utilize the Mission Bio Tapestri® Platform for targeted single-cell DNA analysis to study rigosertib as part of planned clinical trials. Single-cell genomics may identify mutations with far better resolution than that of traditional sequencing methods, allowing a view into each patient's disease at a level never before achieved.  Tapestri will be utilized to identify mutations, including those of the Ras pathway, to monitor a patient's response in clinical trials, supporting the advancement of rigosertib.  By adding the Tapestri Platform to its research and development program, Onconova is including the opportunity to study single cell clones in MDS and determine the sequence of genetic events and the influence of rigosertib on these events along with clinical outcomes.

     
  • In December 2018, Onconova applied to the FDA for a Special Protocol Assessment (SPA) for a Phase 3 trial of oral rigosertib in combination with azacitidine for treatment of first-line higher-risk MDS patients.  The Company expects completion of the FDA's SPA decision before the end of 2019.

     
  • Results from the Phase 2 trial were reported in December 2018 in an oral presentation at the 2018 American Society of Hematology (ASH) meeting and updated at the 2019 European Hematology Association Meeting.       

Additional Progress for Rigosertib and Pipeline Products

  • ON 123300, an investigational first-in-class dual inhibitor of CDK4/6 + ARK5 with the potential to treat a variety of cancers, continues to make progress toward clinical development in the U.S. and China in partnership with HanX.  HanX has conducted toxicology studies to support an IND filing in the U.S.



  • The collaboration with the National Cancer Institute as well as one with a Center of Excellence in Juvenile Myelomonocytic Leukemia, or JMML, for preclinical studies of rigosertib for treatment of pediatric cancer associated RASopathies are ongoing.



  • Onconova continues to participate in important medical and investment conferences. During the second quarter, presentations related to rigosertib development and clinical trials were made at: 

    • 15th Annual International Symposium on MDS/Copenhagen

    • Acute Leukemia Forum/Shanghai

    • BIO International Forum/Philadelphia

    • European Hematology Association/Amsterdam

Upcoming 2019 conferences include:

  • RAS-Targeted Drug Discovery Summit (Boston, September 17-19)
  • Brazilian Association of Hematology, Hemotherapy and Cellular Therapy Congress (Rio de Janeiro, November 6-9)
  • The American Society of Hematology (ASH) Conference in (Orlando,  December 7-10)

Second Quarter 2019 Financial Results

Cash and cash equivalents as of June 30, 2019, totaled $5.9 million compared to $17.0 million at December 31, 2018.  The Company believes that cash and cash equivalents at June 30, 2019, along with additional funds to be received from the HanX license in the third quarter, will be sufficient to fund ongoing trials and operations late into the fourth quarter of 2019.  The Company was notified by Nasdaq on July 26 that Nasdaq has accepted the Company's plan to regain compliance with the stockholders' equity listing requirement by November 18, 2019.

Net loss was $3.6 million for the quarter ended June 30, 2019, compared to $4.3 million for the second quarter ended June 30, 2018. Research and development expenses were $3.9 million for the quarter ended June 30, 2019, and $4.1 million for the comparable period in 2018.  General and administrative expenses were $1.8 million for the quarter ended June 30, 2019, and $2.1 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 Onconova Therapeutics, Inc.

Onconova Therapeutics, Inc. is a Phase 3-stage biopharmaceutical company discovering and developing novel small molecule drug candidates to treat cancer, with a focus on Myelodysplastic Syndromes (MDS).  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.  For more information, please visit http://www.onconova.com.

About Rigosertib

Rigosertib, Onconova's lead candidate, is a proprietary Phase 3 small molecule.  A key publication 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 clinic with oral and IV rigosertib, including single agent IV rigosertib in second-line higher-risk MDS patients (pivotal Phase 3 INSPIRE trial) and oral rigosertib plus azacitidine in first-line 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 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 HR-MDS patients who had progressed on, failed to respond to, or relapsed after previous treatment with an 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.  An interim analysis in early 2018 demonstrated a promising survival signal in the intent-to-treat population as reviewed by the Independent Data Monitoring Committee.  The 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 study 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 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 higher-risk MDS (HR-MDS), after failure of hypomethylating agent, or HMA, therapy.

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 combination therapy modalities.  To date, over 400 patients have been studied with the oral formulation of rigosertib.  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 preliminary efficacy and safety data was presented at The American Society of Hematology Annual Meeting in December 2018.  A Special Protocol Assessment for a pivotal Phase 3 study design is under review by the FDA.
