Item 8.01 Other Events.
Interim Clinical Data of NTLA-2002
On November 12, 2022, the Company announced additional interim results from an ongoing Phase 1/2 clinical study of NTLA-2002 for the treatment of hereditary angioedema (“HAE”). The data presented are from 10 adult patients with HAE in the Phase 1, dose-escalation portion of the study, with a data cut-off date of September 28, 2022. Single doses of 25 mg (n=3), 50 mg (n=4) and 75 mg (n=3) of NTLA-2002 were administered via intravenous infusion, and changes from baseline values of plasma kallikrein protein were measured for each patient.
Administration of NTLA-2002 led to deep, dose-dependent reductions in plasma kallikrein as described below, based on complete cohort biomarker data availability. For the 25 mg and 75 mg cohorts, these deep reductions in plasma kallikrein were sustained through the observation period, which ranged from week 16 to week 32.

HAE attack rates are measured in the dose-escalation portion of the study, with the first analysis occurring at the end of the pre-specified 16-week primary observation period. To date, all patients in the 25 mg and 75 mg dose cohorts have reached the end of this initial observation period in ongoing follow-up as described below. Patients in the 50 mg cohort have not completed the primary 16-week observation period.

At all three dose levels, NTLA-2002 was generally well-tolerated, and the majority of adverse events were mild in severity. The most frequent adverse events were infusion-related reactions, which were mostly Grade 1 and resolved within one day. There have been no dose-limiting toxicities, no serious adverse events and no adverse events of Grade 3 or higher observed to date. No clinically significant laboratory abnormalities were observed.
Intellia expects to select up to two doses to further evaluate NTLA-2002 in the Phase 2, placebo-controlled, dose-expansion portion of the study, which is expected to begin in the first half of 2023. Intellia anticipates expanding country and site participation, including U.S. clinical sites, as part of the Phase 2 study.

Intellia Therapeutics Presents New Interim Data
from First-in-Human Study of NTLA-2002 for the Treatment of
Hereditary Angioedema (HAE) at the American College of Allergy, Asthma & Immunology 2022 Annual Scientific Meeting
follow-up
CAMBRIDGE, Mass., Nov. 12, 2022 (GLOBE NEWSWIRE) – Intellia Therapeutics, Inc. (NASDAQ:NTLA), a leading clinical-stage genome editing company focused on developing potentially curative therapeutics leveraging CRISPR-based technologies, today announced updated data from an ongoing Phase 1/2 clinical study of NTLA-2002 for the treatment of hereditary angioedema (HAE). The interim analyses were shared today in a Distinguished Industry Abstract oral presentation at the American College of Allergy, Asthma & Immunology (ACAAI) 2022 Annual Scientific Meeting, being held November 10 – 14 in Louisville, Kentucky.
The data presented are from 10 adult patients with HAE in the Phase 1, dose-escalation portion of the study, with a data cut-off date of September 28, 2022. Single doses of 25 mg (n=3), 50 mg (n=4) and 75 mg (n=3) of NTLA-2002 were administered via intravenous infusion, and changes from baseline values of plasma kallikrein protein were measured for each patient.

“We see early evidence that our one-time CRISPR-based investigational therapy may offer patients suffering from hereditary angioedema a functional cure for their disease,” said Intellia President and Chief Executive Officer John Leonard, M.D. “Based on the extended data across multiple dose cohorts, we are strongly encouraged that all patients who received a single dose of NTLA-2002 subsequently became attack-free. In the patients with the longest follow-up to date, their attack-free interval has been maintained 5 to 10 months from their last attack. Importantly, the safety data from all 10 patients are highly encouraging, further supporting NTLA-2002’s potential to change the future HAE treatment paradigm. As the second clinical program from our in vivo pipeline to demonstrate deep and consistent protein reduction following a one-time administration, the latest interim data further reinforce the enormous potential of our modular CRISPR genome editing platform to treat a host of genetic diseases.”
At all three dose levels, NTLA-2002 was generally well-tolerated, and the majority of adverse events were mild in severity. The most frequent adverse events were infusion-related reactions, which were mostly Grade 1 and resolved within one day. There have been no dose-limiting toxicities, no serious adverse events and no adverse events of Grade 3 or higher observed to date. No clinically significant laboratory abnormalities were observed.

Intellia expects to select up to two doses to further evaluate NTLA-2002 in the Phase 2, placebo-controlled, dose-expansion portion of the study, which is expected to begin in the first half of 2023. Intellia anticipates expanding country and site participation, including U.S. clinical sites, as part of the Phase 2 study.

About the NTLA-2002 Clinical Program
Intellia’s multi-national Phase 1/2 study is evaluating the safety, tolerability, pharmacokinetics and pharmacodynamics of NTLA-2002 in adults with Type I or Type II hereditary angioedema (HAE). This includes the measurement of plasma kallikrein protein levels and activity as determined by HAE attack rate measures. The Phase 1 portion of the study is an open-label, single-ascending dose design used to identify up to two dose levels of NTLA-2002 that will be further evaluated in the randomized, placebo-controlled Phase 2 portion of the study. This Phase 1/2 study will identify the dose of NTLA-2002 for use in future studies. Visit clinicaltrials.gov (NCT05120830) for more details.
About NTLA-2002
Based on Nobel Prize-winning CRISPR/Cas9 technology, NTLA-2002 is the first single-dose investigational treatment being explored in clinical trials for the potential to continuously reduce kallikrein activity and prevent attacks in people living with hereditary angioedema (HAE). NTLA-2002 is a wholly owned investigational CRISPR therapeutic candidate designed to inactivate the kallikrein B1 (KLKB1) gene, which encodes for prekallikrein, the kallikrein precursor protein. NTLA-2002 is Intellia’s second investigational CRISPR therapeutic candidate to be administered systemically, by intravenous infusion, to edit disease-causing genes inside the human body with a single dose of treatment. Intellia’s proprietary non-viral platform deploys lipid nanoparticles to deliver to the liver a two-part genome editing system: guide RNA specific to the disease-causing gene and messenger RNA that encodes the Cas9 enzyme, which together carry out the precision editing.
About Hereditary Angioedema
Hereditary angioedema (HAE) is a rare, genetic disorder characterized by severe, recurring and unpredictable inflammatory attacks in various organs and tissues of the body, which can be painful, debilitating and life-

threatening. It is estimated that one in 50,000 people are affected by HAE, and current treatment options often include life-long therapies, which may require chronic intravenous (IV) or subcutaneous (SC) administration as often as twice per week, or daily oral administration to ensure constant pathway suppression for disease control. Despite chronic administration, breakthrough attacks still occur. Kallikrein inhibition is a clinically validated strategy for the preventive treatment of HAE attacks.
About Intellia Therapeutics
Intellia Therapeutics, a leading clinical-stage genome editing company, is developing novel, potentially curative therapeutics leveraging CRISPR-based technologies. To fully realize the transformative potential of CRISPR-based technologies, Intellia is pursuing two primary approaches. The company’s in vivo programs use intravenously administered CRISPR as the therapy, in which proprietary delivery technology enables highly precise editing of disease-causing genes directly within specific target tissues. Intellia’s ex vivo programs use CRISPR to create the therapy by using engineered human cells to treat cancer and autoimmune diseases. Intellia’s deep scientific, technical and clinical development experience, along with its robust intellectual property portfolio, have enabled the company to take a leadership role in harnessing the full potential of genome editing to create new classes of genetic medicine.
