On May 2, 2022 Intellia Therapeutics, Inc. (NASDAQ:NTLA), a leading genome editing company focused on developing potentially curative therapies leveraging CRISPR-based technologies, reported the presentation of new preclinical data from its differentiated allogeneic cell engineering platform at Keystone Symposia’s Precision Genome Engineering Conference, taking place April 27 – May 1, 2022, in Keystone, Colorado (Press release, Intellia Therapeutics, MAY 2, 2022, View Source [SID1234613310]). The data presented support the development of NTLA-6001, Intellia’s allogeneic CAR-T development candidate targeting CD30 for the treatment of CD30-expressing hematologic cancers, including relapsed or refractory classical Hodgkin lymphoma (cHL).

"We are pleased to present promising preclinical data that led to the nomination of Intellia’s wholly owned allogeneic development candidate, NTLA-6001, for CD30-expressing hematologic lymphomas. NTLA-6001 is the first candidate using our differentiated allogeneic platform, which leverages a novel combination of sequential, LNP-delivered gene edits to yield T cells shielded from immune rejection," said Intellia Chief Scientific Officer Laura Sepp-Lorenzino, Ph.D. "Our approach to engineering T cells aims to solve key immunological challenges to allogeneicity, while retaining cell attributes necessary for potent and durable tumor killing. We look forward to advancing NTLA-6001 toward IND-enabling activities."
The data shared at Keystone demonstrated that Intellia’s proprietary allogeneic solution created T cells that not only avoided immune recognition by host CD4 and CD8 T cells, but also were protected from NK cell-mediated killing in in vitro and in vivo mouse models. Furthermore, allogeneic T cells engineered sequentially with LNPs retained high viability, cell expansion, memory phenotype, cytotoxic and cytokine secretion characteristics. Intellia’s allogeneic platform can be deployed for TCR-T and CAR-T cell therapy.
As part of these platform advancement efforts, Intellia evaluated multiple CD30 CAR constructs in a series of in vitro and in vivo experiments. The most potent CAR construct showed complete tumor regression and protection from tumor rechallenge in a T cell lymphoma model. This lead allogeneic CAR-T cell candidate, NTLA-6001, is now in preclinical development for cHL and certain CD30+ T cell lymphomas. CD30, the target for NTLA-6001, is a cell surface protein that is often overexpressed in a variety of hematologic cancers, making it an important candidate for CAR-T cell therapy.
