Orna’s Approach & Strategy
We’re reshaping RNA therapeutics to open an entirely new world of possibilities in the treatment of disease. Our field-defining engineered circular RNA (oRNA®) has unmatched advantages compared to linear RNA, and our groundbreaking LNP delivery to sites other than the liver has led the world in unlocking the treatment of a far greater span of diseases than previously addressable.
Limitless Potential
Our vision is to deliver first-in-class innovative RNA drugs wherever they’re needed in the body. Initially focusing on oncology and autoimmune diseases (with our panCAR™ in vivo CAR technology) and infectious disease (with our Merck collaboration), our delivery solutions also open up the possibility of treating certain genetic diseases, such as sickle-cell disease and beta-thalassemia, directly in the bone marrow.
Our technology will allow an immediate, off-the-shelf treatment option that will not require harsh preconditioning regimens, offering a significant advancement over traditional cell engineering therapies.
About Us
Creating a new class of therapeutics requires thinking outside the lines. Comprising a team of skilled scientists, molecular engineers, and industry veterans in addition to a world-class Board of Directors and Scientific Advisors, we are well-suited for to bring the promise of our unique oRNA® and LNP delivery method to patients.

–A single dose of Orna’s anti-CD20 panCAR™ resulted in a significant reduction in non-human primate (NHP) B cells, with sustained depletion observed 7 days after dosing–
–Approach offers a transient and scalable immune cell therapy without the need for lymphodepletion–
WATERTOWN, Mass., December 9, 2024 – Orna Therapeutics, a biotechnology company dedicated to designing and delivering a new class of circular RNA medicines and unprecedented lipid nanoparticle (LNP) delivery solutions for oncology and autoimmune diseases, today presented a poster highlighting new preclinical data that demonstrates the potential of its in vivo panCAR™ platform for the treatment of B cell mediated diseases at the 66th American Society of Hematology (ASH) Annual Meeting taking place in San Diego from December 7-10, 2024.
Orna’s lead LNP candidate, demonstrated effective delivery of oRNA cargo to 60% of splenic T cells and 84% of peripheral blood T cells in non-human primates (NHPs). When paired with an oRNA cargo, the Company’s LNP demonstrated up to ~70% delivery of an anti-CD20 CAR to NHP T cells and human T cells in vitro and maintained expression over 72 hours. A single dose of the anti-CD20 panCAR™ resulted in a 95% reduction in NHP B cells, with sustained depletion (82%) observed 7 days after dosing.
“Our panCAR™ approach combining a synthetic, circular coding RNA platform oRNA® and proprietary immunotropic LNP holds the potential to deliver an entirely novel class of in vivo CAR therapies that eliminate lengthy patient cell processing and lymphodepletion regimens,” said Joe Bolen, Ph.D., Chief Scientific Officer for Orna. “The data presented today at ASH further validate our hypothesis, demonstrating our ability to effectively deliver oRNA cargo and achieve robust and sustained B cell depletion in NHPs, highlighting the potential of our work in advancing our in vivo CAR therapies across both cancer and autoimmune diseases towards the clinic.”
Additional key findings are as follows:
- In cytotoxicity assays, both the anti-CD20 CAR and an anti-CD19 CAR construct killed human B lymphoblast cell lines in vitro.
- In vivo, both the anti-CD19CAR and anti-CD20 CAR oRNAs showed significant B cell depletion that manifested as a 75-80% reduction in B cells in peripheral blood, spleen, and bone marrow at 24 hours. This effect was sustained for 7 days after dosing in peripheral blood and bone marrow.

Lead type V editor program in SCD demonstrates industry leading delivery and repeat dosing with a passive LNP
Results reveal unprecedented improvement of editing rates from single digits to nearly 80% in primary HSPCs
WATERTOWN, Mass., October 22, 2024 /PRNewswire/ – Orna Therapeutics, a biotechnology company dedicated to designing and delivering a new class of circular RNA medicines and unprecedented lipid nanoparticle (LNP) delivery solutions for oncology and autoimmune diseases, today presented a poster highlighting preclinical data from its SiTu Editing in the Marrow (STEM) in vivo CRISPR editing platform at the European Society of Gene & Cell Therapy Annual Congress taking place October 22-25 in Rome.
The data show dramatically improved editing rates from single digits to roughly 80% in primary hematopoietic stem progenitor cells (HSPCs) from healthy donors. Orna’s STEM technology is geared to address beta-hemoglobinopathies including sickle cell disease (SCD) and transfusion-dependent beta thalassemia (TDT).
While significant progress has been made with two recent U.S. Food and Drug Administration approvals for SCD and TDT using ex vivo approaches, patient journeys involve lengthy wait times for treatment at specialized centers and harsh therapeutic regimens that come with serious safety risks that can limit eligibility. By contrast, in vivo delivery of gene editing therapies offers a simple, off-the-shelf treatment that can be administered in an outpatient setting.
“Our results are highly promising and demonstrate the powerful potential of Orna’s type V editors when combined with HSPC-targeted RNA delivery to enable in vivo delivery without the need for a targeting ligand or antibody fragment,” said Robert Mabry, Chief Scientific Officer for Orna. “Orna Therapeutics is pioneering an entirely new approach to genome engineering through the development of our gene editing and in vivo delivery platforms, which could offer more patients access to less toxic and complicated cell-based therapies.”
Utilizing a high-throughput barcoding screening approach in non-human primates (NHPs), the company identified a series of LNPs that demonstrated tropism to a rare population of CD34+ HSPCs that reside in the bone marrow. The technology allows for repeat dosing, which is not currently feasible for viral-based delivery approaches.
The lead HSPC-tropic LNP candidate was found to have greater than 70% reporter-positive bulk CD34+ cells and greater than 95% reporter positive long-term HSCs in humanized mice. Furthermore, when tested individually in NHPs, the LNP candidate showed robust delivery to the bone marrow – revealing an average of 24% reporter positive HSPCs, while multiple doses achieved up to 30% editing.
