Asterias Biotherapeutics to Discuss Cancer Immunot

FREMONT, Calif., May 16, 2018 (GLOBE NEWSWIRE) -- Asterias Biotherapeutics, Inc. (NYSE MKT:AST), a biotechnology company dedicated to developing cell-based therapeutics to treat neurological conditions associated with demyelination and cellular immunotherapies to treat cancer, today announced that Rob Allen, Asterias’ Senior Director of Immunotherapy, will discuss the Company’s cancer immunotherapy product candidate, which is poised to enter the clinic this quarter with the anticipated start of the first in human Phase 1 clinical trial in non-small cell lung cancer (NSCLC), at World Advanced Therapies and Regenerative Medicine Congress in London, England.

The details of the presentation are as follows:

Title : AST-VAC2: An allogeneic dendritic cell immunotherapy entering the clinic in NSCLC Date : Thursday, May 17 Time : 12:40pm BST

About AST-VAC2

AST-VAC2 is an innovative immunotherapy product that contains mature dendritic cells derived from pluripotent stem cells. These non-patient specific (allogeneic) AST-VAC2 cells are engineered to express a modified form of telomerase, a protein widely expressed in tumor cells, but rarely found in normal cells. The modified form of telomerase invokes enhanced stimulation of immune responses to the protein. Similar to an earlier, Asterias-sponsored, hematological cancer program which provided proof-of-concept data, the AST-VAC2 dendritic cells instruct the immune system to generate responses against telomerase and, through this mechanism, target tumor cells. AST-VAC2 is based on a specific mode of action that is complementary to and potentially synergistic with other immune therapies such as checkpoint inhibitors or other immune pathway inhibitors.

About Non-Small Cell Lung Cancer and the AST-VAC2 Trial

Lung cancer (both small cell and non-small cell) is the leading cause of cancer-related death, accounting for about one-quarter of all cancer deaths and more than colorectal, breast, and prostate cancers combined. Non-small cell lung cancer (NSCLC) accounts for about 80% to 85% of lung cancers, according to the American Cancer Society. The three main types of NSCLC are adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. The American Cancer Society’s estimates for lung cancer in the United States for 2017 are: about 222,500 new cases of lung cancer, and about 155,870 deaths from lung cancer. Despite the large number of people afflicted by non-small cell lung cancer, patients remain vastly underserved due to a scarcity of effective treatments. According to statistics published by Cancer Research UK, the five year survival rate for lung cancer patients in England and Wales is less than 10%.

As currently designed, the AST-VAC2 Phase 1 clinical trial will enroll up to twenty-four subjects into one of two cohorts, depending on the stage of their non-small cell lung cancer. The first cohort will evaluate AST-VAC2 in up to 12 subjects with advanced non-small cell lung cancer. Subjects in this cohort, who carry the major histocompatibility gene, HLA-A2, will receive six weekly injections of AST-VAC2 and will be followed for safety, immune responses to telomerase and overall clinical survival. These survival results will be compared directly to a control group who meet all of the other inclusion/exclusion criteria but do not possess the HLA-A2 gene. Assuming safety is demonstrated in the first cohort, enrollment will advance to a second cohort. In the second cohort, early stage subjects who have had successful resection of their tumor with no evidence of metastasis will be enrolled. Up to 12 subjects in this second cohort who carry the major histocompatibility allele HLA-A2 will receive six, weekly injections of AST-VAC2 and will be followed for safety, immune responses to telomerase, overall clinical survival and time to relapse. These survival results will again be compared directly to a control group who meet all of the inclusion/exclusion criteria of cohort 2 but are not HLA-A2+. Subjects will be followed for one year for immune response to telomerase and for 2 years for the survival endpoints. Asterias and Cancer Research UK are exploring the combination of AST-VAC2 with an immune pathway inhibitor.

About Asterias Biotherapeutics

Asterias Biotherapeutics, Inc. is a biotechnology company dedicated to developing cell-based therapeutics to treat neurological conditions associated with de-myelination and cellular immunotherapies to treat cancer. Asterias is presently focused on advancing three clinical-stage programs which have the potential to address areas of very high unmet medical need in the fields of neurology and oncology. AST-OPC1 (oligodendrocyte progenitor cells) is currently in a Phase 1/2a dose escalation clinical trial in spinal cord injury. AST-VAC1 (antigen-presenting autologous dendritic cells) is an autologous cancer immunotherapy targeting telomerase presenting tumor cells, with promising efficacy and safety data from a Phase 2 study in Acute Myeloid Leukemia (AML). AST-VAC2 (antigen-presenting allogeneic dendritic cells) represents a second generation, allogeneic cancer immunotherapy that also targets telomerase presenting tumor cells. The company's research partner, Cancer Research UK, plans to begin a first-in-human (FIH) clinical trial of AST-VAC2 in non-small cell lung cancer.
