Onconova Therapeutics Reports Second Quarter 2022 Financial Results and Provides Business Update

Conference call and live webcast at 4:30 p.m. ET today

NEWTOWN, Pa., Aug. 11, 2022 (GLOBE NEWSWIRE) -- Onconova Therapeutics, Inc. (NASDAQ: ONTX), (“Onconova”), a clinical-stage biopharmaceutical company focused on discovering and developing novel products for patients with cancer, today announced financial results for the three months ended June 30, 2022, and provided a business update.

Highlights for the second quarter of 2022 and recent weeks include:

  • Safety data from the ongoing Phase 1 solid tumor trials of narazaciclib in the United States and China continue to be encouraging with the maximum tolerated dose not yet reached in either study. The trial in the United States is currently enrolling its fifth dose escalation cohort, with continuous dosing. The trial in China is also enrolling its fifth dose escalation cohort but once a day on days 1-21 of 28-day cycles. A protocol amendment to enable further dose escalation in the trial in China is being prepared.
  • Data from in vitro and cell-based assays that suggest narazaciclib’s inhibitory profile may provide safety and efficacy advantages over currently approved CDK4/6 inhibitors were featured in an abstract published at the American Society of Clinical Oncology (ASCO) Annual Meeting.
  • Each of rigosertib’s investigator-sponsored trials continues to progress. A Phase 2 trial evaluating rigosertib plus pembrolizumab in patients with checkpoint inhibitor refractory metastatic melanoma is on schedule to be initiated in the second half of 2022. The expansion cohort of the Phase 1/2a trial of rigosertib plus nivolumab in patients with KRAS-mutated non-small cell lung cancer continues to enroll patients, with additional data from the trial expected in Q3 2022. The Phase 2 trial of rigosertib monotherapy in advanced squamous cell carcinoma associated with recessive dystrophic epidermolysis bullosa also continues to enroll patients.
  • Mark Guerin was appointed Chief Operating Officer in addition to his role as Chief Financial Officer and Dr. Adar Makovski Silverstein was promoted to Senior Director and Head of Corporate Development.
  • Cash and cash equivalents at June 30, 2022 were $46.5 million, which the Company believes will be sufficient to fund ongoing clinical trials and business operations for at least eighteen months.

Management Commentary

“We saw sustained progress across our pipeline over the past months and are well positioned to complete our current Phase 1 trials as we move through the second half of the year,” said Steven M. Fruchtman, M.D., President and Chief Executive Officer of Onconova. “Narazaciclib continues to show a favorable safety profile in its Phase 1 studies, which will be key to informing the design of future trials seeking to address the unmet needs posed by the limitations of currently available CDK4/6 inhibitors. These limitations stem from issues related to safety, tolerability, and primary and acquired drug resistance, which we believe narazaciclib’s differentiated inhibitory profile may overcome. We were pleased to publish preclinical data supporting this hypothesis at the most recent ASCO meeting and look forward to continued efforts to translate these promising findings to the clinic.”

Dr. Fruchtman continued, “Alongside narazaciclib’s advancement, we also made key progress in rigosertib’s investigator-sponsored studies. This includes a Phase 2 trial evaluating rigosertib combined with a PD-1 checkpoint inhibitor in checkpoint inhibitor refractory metastatic melanoma which is on schedule to open for enrollment in the second half of 2022. This study seeks to leverage rigosertib’s immunomodulatory effects and is supported by initial data from the ongoing trial of rigosertib plus anti-PD-1 therapy in KRAS-mutated NSCLC. These data provided strong evidence of the studied doublet’s activity in patients who previously failed checkpoint inhibitor therapy, which is a finding we aim to build upon with the presentation of additional data at a medical meeting later this quarter. Data has been presented, which will be updated, demonstrating that responses seen with rigosertib in this setting are agnostic to the type of KRAS mutation present. This upcoming milestone highlights how rigosertib’s investigator-sponsored studies enable the capital efficient pursuit of value creating opportunities to complement our lead narazaciclib program.”

Second Quarter Financial Results

Cash and cash equivalents as of June 30, 2022, were $46.5 million, compared with $55.1 million as of December 31, 2021. The Company believes that its cash and cash equivalents will be sufficient to fund ongoing clinical trials and business operations for at least eighteen months.

Research and development expenses were $2.0 million for the second quarter of 2022, compared with $1.9 million for the second quarter of 2021.

General and administrative expenses were $2.1 million for the second quarter of 2022, compared with $2.9 million for the second quarter of 2021.
