Asterias Biotherapeutics Reports Milestone Targets for 2018

FREMONT, Calif., Jan. 04, 2018 (GLOBE NEWSWIRE) -- Asterias Biotherapeutics, Inc. (NYSE American:AST), a biotechnology company pioneering the field of regenerative medicine, today provided its 2018 milestones targets for its spinal cord injury and cancer immunotherapy programs after successfully achieving its milestones for 2017.  These achievements, combined with the Company’s financial resources position Asterias to achieve the following milestones during 2018.

ANTICIPATED 2018 MILESTONES

AST-OPC1 – Spinal Cord Injury

  • The Company expects to report 6-month data from Cohort 3 (AIS-A 20 million-cell cohort) and Cohort 4 (AIS-B 10 million-cell cohort) in February 2018, and the 12-month data from Cohorts 3 and 4 in August 2018. 
  • The Company anticipates reporting the six-month top-line readout for the entire study in June 2018 and 12-month top-line readout for the entire study in December 2018.
  • The Company intends to continue discussions with the FDA to achieve clearance on the design of the next study for AST-OPC1. 

AST-VAC2 – Allogeneic Cancer Immunotherapy

  • The Company anticipates the first patient treated to occur in 2018 and the study will enroll up to 24 patients into one of two cohorts, depending on the stage of each patient’s non-small cell lung cancer.
  • Assuming the first patient treated occurs in the first half of 2018, the Company will report the initial safety and immunogenicity readouts in the second half of 2018.

"Asterias achieved significant operational, clinical and regulatory achievements in 2017, highlighted by the 12-month efficacy and safety results from Cohort 2 of our SCiStar Phase 1/2a clinical trial,” said Mike Mulroy, President and Chief Executive Officer.   "We are also excited to have received regulatory clearance in the United Kingdom to initiate the clinical trial of Asterias’ cancer immunotherapy product AST-VAC2 in subjects with early and late stage non-small cell lung cancer (NSCLC).  Having recently completed the enrollment of the SCiStar study at the end of last year, in 2018, we look forward to reporting 6-month and 12-month top-line readouts for the entire SCiStar study and continuing discussions with the FDA to achieve clearance on the design of the next study for AST-OPC1.  We also look forward to initiating enrollment for our AST-VAC2 trial, which is fully funded by Cancer Research UK (CRUK).”

As of December 31, 2017, Asterias' cash and cash equivalents totaled approximately $21.6 million, which includes available-for-sale securities of $8.3 million.  During the 2017 fourth quarter, the Company completed a registered direct offering that raised approximately $10.4 million in gross proceeds.  This, combined with a significantly reduced burn rate entering 2018, provides the Company with sufficient resources to fund is operations through mid-2019.

2017 MILESTONES

AST-OPC1

  • Completed the enrollment of the SCiStar study with a total of 25 subjects enrolled in the study.
  • Published 12-month data from the study’s Cohort 2 (AIS-A 10 million-cell cohort), which included six subjects.  The 12-month data showed that all subjects maintained or improved upon the gains observed at 6 months.  By 12 months, 67% (4/6) of Cohort 2 subjects recovered 2 or more motor levels on at least one side, exceeding the company’s 12-month target of 45-50% of subjects achieving this level of improvement.
  • Reported continued positive safety profile for AST-OPC1 based on trial results to date.
  • Obtained U.S. Food and Drug Administration (FDA) designation as a Regenerative Medicine Advanced Therapy (RMAT) under the 21st Century Cures Act. The RMAT designation is intended to facilitate expedited development, review and approval for important new regenerative medicine therapies for which preliminary clinical evidence indicates the potential to address a serious or life-threatening disease or condition.
  • In August 2017, the company published new efficacy and safety data from preclinical studies of AST-OPC1 in the peer-reviewed journal “Stem Cells Translational Medicine.”  The preclinical studies described in this paper were among those submitted in Asterias’ 2014 Investigational New Drug Amendment in support of the SCiStar trial.

AST-VAC

  • Received regulatory clearance in the United Kingdom to initiate the clinical trial of Asterias’ cancer immunotherapy product AST-VAC2 in subjects with early and late stage non-small cell lung cancer (NSCLC). This First-In-Human (FIH) trial, which is being sponsored and managed by Cancer Research UK, will examine the safety, tolerability, immunogenicity and activity of AST-VAC2 in subjects with NSCLC.
  • Published positive AST-VAC1 Phase 2 clinical data in Acute Myeloid Leukemia in 'Cancer,' a leading peer-reviewed journal of the American Cancer Society.
