Updated Interim Clinical Data of NTLA-2001
On November 2, 2023, Intellia presented additional interim results from its ongoing Phase 1 study of NTLA-2001, an investigational, in vivo CRISPR/Cas9 genome editing therapy in development as a single-dose treatment for transthyretin (ATTR) amyloidosis, at the 4th International ATTR Amyloidosis Meeting in Madrid, Spain. The data presented today, with a cutoff date of May 11, 2023, are from the initial 65 out of 72 patients dosed in the Phase 1 study, which has now completed enrollment. In the newly reported dose-expansion portion, administration of NTLA-2001 at the 55 mg and 80 mg dose led to deep serum TTR reductions consistent with the results previously reported from patients in the dose-escalation portion who received the corresponding weight-based dose, 0.7 mg/kg and 1.0 mg/kg, respectively.
Across all patients who received a dose of 0.3 mg/kg or higher (n=62), the median serum TTR reduction was 91% and the median absolute residual serum TTR concentration was 17 µg/mL at day 28. The reduction of serum TTR compared to baseline was sustained through the latest follow-up. With 29 patients now reaching at least 12 months of follow-up, all patients continued to show a long-lasting response with no evidence of loss in activity over time.
NTLA-2001 was generally well tolerated across all patients and at all dose levels tested. The most commonly reported adverse events were infusion-related reactions, which occurred in 38% of patients. The majority of adverse events, including infusion-related reactions, were Grade 1 or 2 in severity, transient and resolved spontaneously. Other adverse events that were reported in greater than 10% of patients included headache, diarrhea and back pain, and were all Grade 1 or 2. All patients received a full dose of NTLA-2001 and remain on study. No dose-limiting toxicities were observed. Based on the safety and activity of NTLA-2001, the 55mg dose has now been selected to be evaluated in the upcoming pivotal Phase 3 study.

These forward-looking statements include, but are not limited to, express or implied statements regarding Intellia’s beliefs and expectations regarding: the safety, efficacy and advancement of its clinical program for NTLA-2001 for the treatment of transthyretin (“ATTR”) amyloidosis pursuant to its clinical trial applications (“CTA”) and investigational new drug (“IND”) submissions, including the expected timing of data releases, regulatory filings, and the initiation and completion of clinical trials such as its ability to initiate a global pivotal Phase 3 trial by year-end; its ability to generate data to demonstrate NTLA-2001 as a potential single-dose treatment for ATTR amyloidosis; its ability to maintain and expand its related intellectual property portfolio, and avoid or acquire rights to valid intellectual property of third parties; and the timing of regulatory filings and clinical trial execution, including enrollment and dosing of patients.
Any forward-looking statements in this press release are based on management’s current expectations and beliefs of future events, and are subject to a number of risks and uncertainties that could cause actual results to differ materially and adversely from those set forth in or implied by such forward-looking statements. These risks and uncertainties include, but are not limited to: risks related to the initiation and conduct of a global pivotal Phase 3 study for NTLA-2001 for the treatment of ATTR-CM and that the results of such Phase 3 study may not be positive; risks related to Intellia’s ability to protect and maintain its intellectual property position; risks related to the authorization, initiation and conduct of studies and other development requirements, including manufacturing, for NTLA-2001; the risk that any one or more of Intellia’s product candidates, including NTLA-2001, will not be successfully developed and commercialized; the risk that the results of preclinical studies or clinical studies, including for NTLA-2001, will not be predictive
