Research Publication Demonstrates Utility of Applied DNA’s LinearDNA™ in Non-Viral CAR T Manufacturing

On November 9, 2021 Applied DNA Sciences, Inc. (NASDAQ: APDN) (Applied DNA or the "Company"), a leader in Polymerase Chain Reaction (PCR)-based DNA manufacturing and nucleic acid-based technologies, reported the publication of a study in Molecular Therapy: Methods and Clinical Development on a methodology for the manufacture of novel types of CAR constructs that employ the Company’s LinearDNA as part of a manufacturing process for the efficient generation of CD19-specific CAR T-cells (CAR19 T-cells) based on co-electroporation of a LinearDNA transposon and mRNA encoding of piggyBac transposase (Press release, Applied DNA Sciences, NOV 9, 2021, View Source [SID1234594870]). PCR-produced LinearDNA is manufactured by LineaRx, the Company’s majority-owned subsidiary, to serve as a pure, fast, and flexible alternative to plasmid DNA (pDNA) for biotherapeutic applications.

The study, titled "Enzymatically produced piggyBac transposon vectors for efficient non-viral manufacturing of CD19-specific CAR T cells", details the utility of LinearDNA in the cost-effective production of preclinical CAR T cells. Its authors, members of the Institute of Hematology and Blood Transfusion (ÚHKT) in Prague, Czechia, and the Faculty of Natural Sciences at Charles University, also in Prague, propose that the combination of LinearDNA and a transposon/transposase system offers therapy developers an effective research tool for making experimental CAR T cells rapidly and efficiently without the need for complicated virus production or the use of pDNA.

Pavel Otáhal, contributing author and Head of the Gene Immunotherapy Research Department at ÚHKT, stated, "Our study compares the manufacture of CAR19 T-cells via PCR-made transposon DNA (LinearDNA) with mRNA encoding of the transposase against a conventional plasmid approach. We found CAR T efficacy of the LinearDNA system versus the plasmid system to be identical. Further, we found no mutations in the coding sequence of LinearDNA and with >99% purity that obliviated the need for purification typical of a plasmid approach. As an institution dedicated to diagnosing and treating serious blood diseases and with the ability to pursue investigational medicines from development to manufacture and clinical trial for patients who have exhausted all approved treatment options, having a cost-effective and rapid production chain is integral to ÚHKT’s mission. We find LinearDNA to be an excellent platform for CAR T-cell therapy development."

Dr. James A. Hayward, president and CEO of Applied DNA, said, "The clinical successes of CAR T-cell therapy against blood cancers have been impressive, though limited by the complex production of viral vectors that are currently needed for T-cell genetic transformation and the use of pDNA. These manufacturing complexities have likewise hindered research on CAR T-cell therapies. As described in the publication, the use of LinearDNA, coupled with non-viral transfection systems, we believe, overcomes many of the existing manufacturing complexities associated with pDNA and viral vectors, thereby offering therapy developers a rapid and cost-effective tool for manufacturing preclinical CAR T cells. The authors’ findings as it relates to LinearDNA coincide with the industry’s growing interest in alternatives to pDNA for CAR T-cell therapies with approximately 50% of recent CRO orders coming from CAR T cell developers."

Rarecells, Inc. to fund a clinical study at Columbia University of its ISET® -AML test for early detection of Acute Myeloid Leukemia (AML)

On November 9, 2021 Rarecells, Inc., a healthcare company in the field of liquid biopsy, focused on the development and commercialization of non-invasive tests for early cancer detection, reported that it has entered into an agreement with Columbia University to fund a clinical study evaluating its ISET -AML test for early detection of acute myeloid leukemia (AML) in patients with myelodysplastic syndrome (MDS) (Press release, RARECELLS, NOV 9, 2021, https://www.prnewswire.com/news-releases/rarecells-inc-to-fund-a-clinical-study-at-columbia-university-of-its-iset–aml-test-for-early-detection-of-acute-myeloid-leukemia-aml-301420287.html [SID1234594918]).

The study, expected to begin in Q1 2022, will be the first clinical evaluation of the ISET -AML test. Azra Raza, M.D., Professor of Medicine at Columbia University Vagelos College of Physicians and Surgeons and Director of the MDS Center at Columbia University’s Herbert Irving Comprehensive Cancer Center, is the study’s principal investigator.

This clinical study aims to assess the clinical performance of the ISET -AML test in the context of early AML detection.

Myelodysplastic syndromes are a group of diverse bone marrow disorders in which the bone marrow does not produce enough healthy blood cells. For roughly 30% of the patients diagnosed with MDS, this type of bone marrow failure syndrome will progress to AML, which is often fatal. Currently, patients with MDS are monitored with blood tests to measure complete blood cell counts and bone marrow analyses to detect the appearance of leukemic blasts heralding the development of AML. However, blood tests have a very low sensitivity to detect rare blasts and bone marrow tests involve an invasive procedure that cannot be repeated frequently. As a result, AML is often diagnosed when it is already well established and may be resistant to available treatment options.

The ISET patented EC-marked platform is able to extract down to one single cancer cell of any type from 10 ml of blood, thus a tumor cell mixed with 100 million leukocytes and 50 billion erythrocytes, according to peer-reviewed published studies. The ISET -AML test uses the ISET platform to extract from blood the rare leukemic blast cells with unsurpassed sensitivity and detect them through suitable markers labelling, image analysis and AI.

Dr. Raza, who wrote the best-selling book "The First Cell and the Human Costs of Pursuing Cancer to the Last," said: "New non-invasive tests are needed to detect the first leukemic cells in the blood of MDS patients so that we can identify and treat patients at risk of developing AML before the disease becomes established."

Patrizia Paterlini, President and Chief Executive Officer of Rarecells, said: "We are pleased to be working with Columbia University’s Herbert Irving Comprehensive Cancer Center to conduct the first clinical evaluation of the ISET -AML test in patients with MDS. The strategic decision to transition the ISET -AML test to an investigator-sponsored study at Columbia will provide access to world-class expertise and has the potential to accelerate patients’ recruitment in order to expedite our clinical study. We look forward to a continued progress across our ISET Early Cancer Detection program, which also includes ongoing studies in patients at risk of Prostate Cancer".

About Selinexor (ATG-010)

Selinexor is so far the first and only oral XPO1 inhibitor approved by the U.S. Food and Drug Administration (FDA) and the first drug approved for the treatment of both multiple myeloma and diffuse large B-cell lymphoma. By blocking the nuclear export protein XPO1, selinexor can promote the intranuclear accumulation and activation of tumor suppressor proteins and growth regulating proteins, and down-regulate the levels of multiple oncogenic proteins, thus induces apoptosis without affecting normal cells. Due to its novel mechanism of action, selinexor can be used in multiple combination regimens to improve treatment efficacy.
