Ahead of the Curve

ORNA’S APPROACH & STRATEGY

Orna Therapeutics is leaving linear thinking behind to create fully engineered oRNATM circular RNAs – an entirely new class of RNA medicines that can realize the full potential of RNA and which is poised to change the way we treat disease. By marrying the power of oRNATM with superior delivery techniques, we are pioneering the next breakthrough in RNA therapeutics.

LIMITLESS POTENTIAL

Orna’s technology has a breadth of applications across multiple disease areas including cancer, regenerative medicine, protein replacement, infectious diseases, and autoimmunity. Our lead program is an in situ CAR therapy that combines oRNATM molecules and proprietary lipid nanoparticles (LNPs) to deliver chimeric antigen receptors (CARs) directly to patient’s immune cells within the body (isCARTM therapy).

Our Team

Creating a new class of therapeutics requires thinking outside the lines. Comprised of a team of skilled scientists, molecular engineers, and industry veterans in addition to a world class Board, we are well-suited for the challenge of bringing the promise of our oRNATM therapeutics to patients.

Orna Therapeutics Announces First-in-Class, Breakthrough Data Demonstrating Potential of Circular RNA Platform at ASGCT 2022

Advances in oRNA expression and delivery enable pipeline of therapeutics across a diverse range of disease areas

Lead isCAR program shows possibility of tumor eradication in preclinical animal models with promise of translation to non-human primates and patients

Cambridge, Mass., May 16, 2022 – Orna Therapeutics, a biotechnology company pioneering a new class of fully engineered circular RNA (oRNA) therapies, today for the first time announces data from its lead isCARprogram that validates the potential of the company’s novel oRNA technology and LNP delivery platform. Based on advances in the expression of oRNA as well as its delivery to immune cells, Orna has demonstrated tumor suppression and eradication in an animal model pointing to the possibility that oRNA-LNP based cancer therapies could eventually overtake cell therapies.

Additional data to be presented demonstrate the utility of Orna’s proprietary FoRCE screening platform which has enabled the company to discover and characterize a major new resource for protein expression based on internal ribosome entry sites (IRESs). Orna will also present data showing the development of novel immunotropic lipid nanoparticles (LNPs), and the potential of oRNA in genetic muscle disease and vaccines. View full presentations from ASGCT on our website here.

“At Orna, we’ve created the world’s leading circular RNA company and are building a platform and pipeline with the potential to change the way we treat disease,” said Tom Barnes, PhD, Orna’s Chief Executive Officer and oral presenter at ASGCT. “Presented for the first time, these data suggest our oRNA technology and LNP delivery favorably combine to maximize our reach into multiple therapeutic areas – validating our expanded pipeline beyond cancer to include muscle genetic diseases and vaccines.”

isCAR: Revolutionizing CAR-T Cell Therapy with the Possibility of Eradicating Tumors

Our lead program is an in situ CAR therapy that combines oRNA and custom engineered LNPs to create modified immune cells within the patient. This easily redosable format would not require patient lymphodepletion and would allow for reliable dose control, overcoming barriers of ex vivo CAR-Ttherapies. Data being presented demonstrate that oRNA-LNP can eradicate cancer cells in an animal model. Additional iterative data in rodents and non-human primates gives Orna confidence that this may successfully translate into humans.

“We are excited about the preclinical results in our lead isCAR program as we clearly see the opportunity to overcome significant hurdles in current ex vivo approaches, suggesting that oRNA-LNP based cancer therapies may eventually overtake cell therapies,” said Robert Mabry, PhD and Chief Scientific Officer at Orna. “We believe that data from iterative animal studies can support our plans to deliver in situ CAR-T therapies to the clinic.”

FoRCE: Formulated oRNA Cell-based Evaluation Platform

Orna is also presenting new data from our proprietary FoRCE screening platform, which captures the entire oRNA production, formulation, and evaluation process in an arrayed and automated format. In a first application, Orna has screened and characterized thousands of IRES elements in multiple primary human cell types. IRES identification and development is critical for optimizing oRNA function via tunable protein expression. Orna has discovered many novel IRES elements that drive oRNA expression to levels well above those of standard IRES elements, including some that show differential activity across cell types. These results open a new technological toolkit for driving protein expression from circular RNA.

Breadth of Platform

Orna has extended its oRNA-LNP technology into several other indications including Duchenne Muscular Dystrophy and vaccines and believes there are many additional opportunities this technology can bring to existing therapeutics.

Duchenne Muscular Dystrophy (DMD):

Orna will present data highlighting the ease of working with very large oRNAs. Data demonstrate, for the first time, non-viral delivery of a large, full-length, dystrophin-encoding RNA in human cells, as well as in vivo delivery of smaller length versions in mouse models. These data are an encouraging first step on the path to delivering full-length gene therapy to patients with DMD.

Vaccines:

Orna is investigating the suitability of oRNA combined with intramuscularly administered immunotropic LNPs for vaccine applications, including for COVID-19. The oRNA half-life observed in muscle and immune cells, combined with the intramuscular administration of immunotropic lipids, suggests that oRNA-LNP technology may be beneficially applied to vaccine development.
