Onconova Therapeutics, Inc. Reports Recent Business Highlights and Second Quarter 2017 Financial Results
NEWTOWN, Pa., Aug. 15, 2017 (GLOBE NEWSWIRE) -- Onconova Therapeutics, Inc. (NASDAQ:ONTX), 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), today provided a corporate update and reported financial results for the second quarter ended June 30, 2017.
“We are advancing IV rigosertib in a late stage clinical trial for patients with unmet medical needs in MDS. Our Phase 3 INSPIRE trial with IV rigosertib is enrolling globally and the next milestone of interim analysis is anticipated in the fourth quarter,” said Dr. Ramesh Kumar, President and Chief Executive Officer.
“After consulting with regulators in the US and Europe following Phase 1/2 data with oral rigosertib in combination with azacitidine, we are designing a Phase 3 trial in first-line higher risk MDS patients for submission under a Special Protocol Assessment," continued Dr. Kumar. "We also believe there is interest for our pediatric RASopathies rare disease collaborative program from the National Cancer Institute, academia, and patient advocacy which we find extremely gratifying.”
INSPIRE Trial of IV Rigosertib in 2nd Line Higher-risk (HR) MDS
- The INSPIRE protocol allows for a pre-planned interim analysis. This analysis will be triggered after reaching 88 events (deaths). Although it is difficult to accurately forecast the timing of this milestone, based on when we expect to finalize our statistical analysis plan, enrollment statistics, and our expectations for survival of the trial population, we anticipate this to occur in Q4-2017.
- The Statistical Analysis Plan (SAP) for interim and top-line analysis is under review by the Food and Drug Administration (FDA) and the European Medicines Agency (EMA).
- As of July 31, 72 sites in 16 countries across four continents have enrolled patients for this study. Countries and trial sites were carefully chosen to ensure availability of appropriate patients meeting stringent eligibility criteria. Since these criteria were purposely designed to be narrow and selective, extensive eligibility verification and trial site education are integral to our plan.
- Enrollment for the trial has slowed recently, which could be related to seasonality. The Company is taking proactive measures to increase enrollment including the addition of trial sites in three new countries and changes within its CRO group. Should enrollment not return to desired levels, full enrollment may be delayed by several months.
Oral Rigosertib in Combination with Azacitidine for 1st-line HR-MDS
Pivotal Phase 3 Trial Protocol
- Following receipt of the final minutes from our End-of-Phase 2 discussion with the FDA in 3Q-2016, a Scientific Advice process was initiated with the EMA and was completed in July. Based on this feedback, we are designing a Phase 3 protocol for a 1:1 randomized controlled trial of oral rigosertib + azacitidine compared with azacitidine + placebo in first-line patients with HR-MDS. We plan to initiate the FDA Special Protocol Assessment (SPA) process following completion of the ongoing Expansion Phase 1/2 trial.
- Initiation of the trial, which is planned to be conducted globally, requires additional financing.
Expansion of Phase 1/2 Trial of Oral Rigosertib in Combination with Azacitidine
- This expansion phase is designed to enroll up to approximately 40 patients. The key objectives are to optimize dosing and schedule of administration of oral rigosertib in combination with azacitidine.
- After appropriate amendments were filed with the regulatory agencies, we started the expansion phase of this trial. Four sites are now open in the U.S. and we plan to activate additional sites in US, Europe and Australia. The first patient was enrolled in April.
Other Programs for Future Development or Partnership and Presentations
New Collaborative Program in “RASopathies”: Rare Disease in Children
- Based on new mechanism of action data published last year (Cell, 2016), we initiated a collaborative development program focusing on a group of rare diseases, RASopathies, which share a well-defined molecular basis in expression or defects involving Ras Effector Pathways. Pediatric “RASopathies” is a subset of these rare diseases, and we are embarking on a multifaceted collaborative program involving patient advocacy, government, and academic organizations. In addition to drug supply and expertise, we believe we can contribute organizational oversight to this project.
- We expect to execute a formal Collaborative Research and Development Agreement (CRADA) with the National Cancer Institute (NCI) of the National Institutes of Health.
- Investigators in the NCI have designed a protocol for a trial in pediatric patients with certain RASopathies complicated by cancer.
- Since our focus area of MDS is related to a pediatric rare disease, Juvenile Myelomonocytic Leukemia (JMML), we are exploring collaboration with an academic group focused on development of novel therapeutics for these children. Initial non-clinical studies in Stem Cells and animal models may influence the design of an appropriate clinical study in this patient population.
- In July 2017, we presented a summary of our targeted approach to a symposium organized by Rasopathiesnet.org, a patient advocacy organization. We are also sponsoring an educational event (a “Key Opinion Leader” breakfast) in the fourth quarter to bring together disease area experts, patient advocacy groups and our knowledge, to draw attention to this unmet medical need and the potential for rigosertib in this quest.
- The Company presented a poster at the American Society of Clinical Oncology Annual Meeting on Monday, June 5th focusing on “Further Rationale for Rigosertib in a Second-line HR-MDS Setting.” Bone marrow response was evaluated as a surrogate for survival in this trial of 64 patients who had failed hypomethylating agents. 22% of these patients achieved marrow complete response (mCR) and 47% of patients achieved disease stabilization.
- The Company contributed multiple presentations at the 22nd Congress of the European Hematology Association on June 24th. The presentations incorporated clinical and non-clinical data evaluating oral rigosertib plus azacitidine. The data presented demonstrated that the combination may overcome hypomethylating agent resistance, and also indicates that further study in acute myeloid leukemia is warranted. SymBio, Onconova’s partner in Japan and Korea, presented Phase 1 safety data for intravenous rigosertib in Japanese patients with recurrent/relapsed or refractory Myelodysplastic Syndromes.
- Dr. Steven Fruchtman, Onconova’s Chief Medical Officer, highlighted approaches for studying rigosertib in RAS-associated cancers on Sunday, July 30th at the 5th International RASopathies Symposium organized by RASopathies Network. The primary focus of this presentation was JMML, which is incurable without an allogenic hematopoietic stem cell transplant.
Proprietary Preclinical Next Generation CDK4/6 + ARK5 Inhibitor
- New CDK inhibitors are making an impact for patients with breast and lung cancers. These orally available agents have potential utilities in a broad range of solid tumors and we believe will become an integral part of cancer therapy in the future.
- Our CDK inhibitor is differentiated from other agents on the market (such as Palbociclib, Ribociclib and Abemaciclib) or in development (such as the compounds being developed by G1 Therapeutics) by its dual inhibition of CDK4/6 + ARK5. We continue to carry out preclinical research to enhance the data package for this compound in an attempt to seek partners for co-development of this novel new chemical entity.
Second-Quarter Business Highlight:
- On April 26, 2017, Onconova closed a public offering resulting in gross proceeds of approximately $5.2 million, before underwriting discounts, commissions and estimated offering costs. New institutional investors, existing investors, as well as Directors and Management of the Company participated in the round. On May 17, 2017, the underwriters exercised their option to purchase an additional 363,580 shares, which resulted in additional gross proceeds of $0.8 million.
Second-Quarter Financial Results:
- Cash, cash equivalents, and marketable securities as of June 30, 2017 totaled $15.0 million, compared to $21.4 million as of December 31, 2016.
- Total net revenue was $0.3 million for the second quarter of 2017 and $0.5 million for the six months ended June 30, 2017, compared to $2.2 million and $3.7 million, respectively, for the comparable periods in 2016.
- Research and development expenses were $4.6 million for the second quarter of 2017 and $9.5 million for the six months ended June 30, 2017, compared to $5.6 million and $11.4 million, respectively, for the comparable periods in 2016.
- General and administrative expenses were $1.8 million for the second quarter of 2017 and $3.9 million for the six months ended June 30, 2017, compared to $2.1 million and $5.3 million, respectively, for the comparable periods in 2016.

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. The advanced clinical trial with the Company’s lead compound, rigosertib, is aimed at what the Company believes are unmet medical needs of patients with MDS. For more information, please visit http://www.onconova.com.
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 the randomized Phase 3 international INSPIRE trial for patients with higher-risk (HR) MDS, after failure of hypomethylating agent, or HMA, therapy. This formulation is intended for patients with advanced disease, to provide long duration of exposure, and to ensure dosing under a controlled setting.
The INternational Study of Phase III IV RigosErtib, or INSPIRE, is based on guidance received from the U.S. Food and Drug Administration and European Medicines Agency and derives from the analysis 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 the National Comprehensive Cancer Network (NCCN) Guidelines. The trial will enroll approximately 225 patients 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 and an interim analysis is anticipated. 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 also supports 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 US patent with earliest expiration in 2028.
