(NASDAQ:NTLA), a leading clinical-stage gene editing company focused on revolutionizing medicine with CRISPR-based therapies, today presented new data demonstrating for the first time the potential for redosing with an investigational, in vivo CRISPR/Cas9 genome editing therapy. These data from the ongoing Phase 1 study of NTLA-2001, a single-dose treatment in development for transthyretin (ATTR) amyloidosis, were presented at the Peripheral Nerve Society Annual Meeting, taking place June 22–25 in Montreal, Canada. “Today’s data showcase an exciting new platform advancement for Intellia and the field of gene editing. For the first time ever, we demonstrated that redosing with CRISPR, utilizing our proprietary, non-viral LNP-based delivery platform, enabled an additive pharmacodynamic effect on the target protein,” said Intellia President and Chief Executive Officer John Leonard, M.D. “While redosing is not planned for the NTLA-2001 program for the treatment of transthyretin amyloidosis, part of our commitment to patients enrolled in the dose-escalation portion of the Phase 1 study was to provide them with the opportunity to receive the therapeutic dose selected if they did not reach the target protein reduction level. These data provide platform proof-of-concept that we can re-dose, if necessary, enabling us to pursue treatment of other diseases where patients might need more than one dose to reach the desired therapeutic effect.” NTLA-2001 is currently being evaluated in patients with either ATTR amyloidosis with cardiomyopathy (ATTR-CM) or hereditary ATTR amyloidosis with polyneuropathy (ATTRv-PN).
