FREMONT, Calif., Aug. 14, 2017 (GLOBE NEWSWIRE) -- Asterias Biotherapeutics, Inc. (NYSE MKT: AST), a biotechnology company pioneering the field of regenerative medicine, today reported financial and operational results for the quarter ended June 30, 2017, as well as recent corporate progress.

"We made significant progress during the second quarter and in recent months in our two lead development programs: our AST-OPC1 program in spinal cord injury and our AST-VAC2 cancer immunotherapy program in non-small cell lung cancer," said Mike Mulroy, President and Chief Executive Officer of Asterias.  "We reported encouraging data from our SCiStar study that shows meaningful improvements in arm, hand, and finger function in patients with severe cervical spinal cord injuries.  Importantly, these improvements have been sustained—and in some cases further improved—at nine months following administration of AST-OPC1.  In our cancer immunotherapy program, we recently completed a major step toward advancing AST-VAC2 into the clinic.  In particular, together with our research partner Cancer Research UK, we successfully completed the production of the first cGMP clinical grade lot of AST-VAC2.  This lot of AST-VAC2 provides the initial clinical trial material for patients enrolling in the upcoming clinical study evaluating AST-VAC2 in non-small cell lung cancer. Lastly, we continue to be mindful of our cost structure as we advance our programs and make adjustments to our operating expenses where appropriate."

2017 Upcoming Milestones

• In late third quarter or early fourth quarter of 2017, Asterias will report 12-month data from the AIS-A 10 million cell cohort in the SCiStar Phase 1/2a clinical study of AST-OPC1 in complete cervical spinal cord injury.
• Asterias expects to complete patient enrollment with a total of between 25-30 subjects in the SCiStar study by the end of 2017.
• In the second half of 2017, Asterias expects to have all necessary regulatory clearances to commence the first clinical study of the company's cancer immunotherapy product candidate AST-VAC2 in non-small cell lung cancer.
• By the end of 2017, Asterias expects to have up to three sites opened and patient enrollment initiated in the AST-VAC2 clinical study.

Second Quarter 2017 and Recent Key Achievements

During the second quarter, the company continued to provide promising updates on recovery of arm, hand and finger function for patients that have been administered AST-OPC1:

• Reported nine-month data from the AIS-A 10 million cell cohort that showed improvements in arm, hand, and finger function observed at three months and six months following administration of AST-OPC1 were confirmed and in some patients further increased at nine months.  The results suggest a meaningful and favorable improvement to date in recovery of arm, hand, and finger function in patients treated with the 10 million cell dose of AST-OPC1 compared to the level of expected rates of spontaneous recovery based on historical control data of a closely matched patient population.
• Reported new MRI data from the SCiStar study that indicates AST-OPC1 cells have durably engrafted in patients post-implantation, and have the potential to prevent lesion cavity formation, possibly reducing spinal cord tissue deterioration after spinal cord injury.
• Lucas Lindner of Eden, Wisconsin, a former quadriplegic patient who has regained functional use of his fingers, hands, and lower arms after receiving 10 million cells of AST-OPC1 in the SCiStar study, threw out the ceremonial first pitch at a Major League Baseball game on August 13, 2017.

Management executed well to drive forward the AST-OPC1 program, particularly as it relates to enrollment, and will be providing additional data readouts for a growing number of patients in early 2018:

• Completed enrollment and dosing in the AIS-B 10 million cell and AIS-A 20 million cell cohorts of the SCiStar study in July. The company has completed enrollment and dosing in four of the five planned cohorts in this study. 
• Enrollment and dosing of the fifth patient in the AIS-A 20 million cell cohort triggered the final $1.5 million grant payment from the California Institute for Regenerative Medicine (CIRM) under the existing $14.3 million Strategic Partnerships Award grant awarded to Asterias.  Asterias expects to receive this grant payment in the third quarter of 2017.   
• Enrolled and dosed first patient in fifth and final cohort in the SCiStar study.  Twenty-two patients have been administered AST-OPC1 in the SCiStar study and twenty-seven patients have been administered AST-OPC1 after including patients from a previous Phase 1 safety trial. 
• The FDA accepted the company's amendment to the clinical research protocol for the SCiStar study. The amendment expands the eligibility criteria to include patients with a C-4 spinal cord injury and extends the dosing window to allow for administration of AST-OPC1 at up to 42 days post-injury.
• Opened two additional clinical sites for the SCiStar study, providing additional geographical reach and previous experience with spinal cord injury trials. Asterias now has eight clinical sites throughout the country enrolling patients in the study.

Management is making progress related to its cancer immunotherapy programs as its AST-VAC2 program gets closer to entering the clinic:

• Published positive AST-VAC1 Phase 2 clinical data in Acute Myeloid Leukemia in 'Cancer,' a leading peer-reviewed journal of the American Cancer Society.
• Cancer Research UK, supported by Asterias technical personnel, successfully completed the manufacture of the first cGMP (current Good Manufacturing Practice) clinical grade lot of AST-VAC2, which met all release specifications. This lot will provide initial clinical trial material for patients enrolling in the upcoming Phase 1/2a study evaluating AST-VAC2 in non-small cell lung cancer.

Financial Results

Cash and cash equivalents as of June 30, 2017 were $11.9 million, while available-for-sale securities were $13.1 million.  The combined total of cash, cash equivalents, and available-for-sale securities totaled $25.0 million.
