First Quarter 2023 and Recent Operational Highlights

In Vivo Program Updates

Transthyretin (ATTR) Amyloidosis

• NTLA-2001: NTLA-2001 is an in vivo, systemically delivered, investigational CRISPR-based therapy designed to inactivate the TTR gene in liver cells and thereby prevent the production of transthyretin (TTR) protein for the treatment of ATTR amyloidosis. NTLA-2001 offers the possibility of halting and reversing the disease by driving a deep, consistent and potentially lifelong reduction in TTR protein after a single dose. NTLA-2001 is subject to a co-development/co-promotion agreement between Intellia, the lead party for this program, and Regeneron Pharmaceuticals, Inc.
  • ATTR Amyloidosis with Cardiomyopathy (ATTR-CM):
    • Intellia plans to submit a U.S. Investigational New Drug (IND) application in mid-2023. Subject to regulatory feedback, the Company anticipates initiating a global pivotal trial for ATTR-CM by year-end 2023.
    • The Company expects to present additional data from the ATTR-CM arm of the Phase 1 study in 2023, including longer-term safety and durability data, as well as emerging clinical endpoints.
  • Hereditary ATTR Amyloidosis with Polyneuropathy (ATTRv-PN):
    • As previously announced, during the first quarter of 2023, the planned enrollment of the dose-expansion portion of the ATTRv-PN arm in the Phase 1 study was completed to inform a pivotal study. The Company is actively preparing for a global pivotal study, which includes discussions with regulatory authorities.
    • Intellia recently began redosing patients in the 0.1 mg/kg cohort (n=3), the initial cohort and lowest dose tested in the dose-escalation portion of the Phase 1 study, with the 55 mg dose selected for the dose-expansion cohort.
    • The Company plans to present additional clinical data from the ATTRv-PN arm of the Phase 1 study in 2023.

Hereditary Angioedema (HAE)

• NTLA-2002: NTLA-2002 is a wholly owned, in vivo, systemically delivered investigational CRISPR-based therapy. NTLA-2002 is designed to knock out the KLKB1 gene in the liver, with the potential to permanently reduce total plasma kallikrein protein and activity, a key mediator of HAE. This investigational approach aims to prevent attacks for people living with HAE by providing continuous reduction of plasma kallikrein activity, following a single dose. It also aims to eliminate the significant treatment burden associated with currently available HAE therapies. NTLA-2002 is being evaluated in a Phase 1/2 study in adults with Type I or Type II HAE.
  • Intellia announced today that the first patient has been dosed in the global Phase 2 portion of its Phase 1/2 clinical trial of NTLA-2002. Based on encouraging study interest from both investigators and patients, the Company expects to complete enrollment (n=25) in 2H 2023.
  • The Company announced in March that the U.S. Food and Drug Administration (FDA) cleared the NTLA-2002 Phase 2 IND application. Additionally, the FDA granted Regenerative Medicine Advanced Therapy (RMAT) designation to NTLA-2002 for the treatment of HAE.
  • In January 2023, Intellia was awarded the Innovation Passport for NTLA-2002 by the U.K. Medicines and Healthcare products Regulatory Agency (MHRA). The Innovation Passport is the point of entry into the U.K.’s Innovative Licensing and Access Pathway (ILAP), which is designed to accelerate time to market and facilitate patient access to innovative medicines.
  • The Company plans to present additional clinical data from the Phase 1 portion of the first-in-human study in 2023. Data expected to be presented include updated safety, durability of pharmacodynamic effect and attack-rate measures from all three patient cohorts.

Alpha-1 Antitrypsin Deficiency (AATD)

• NTLA-3001 for Associated Lung Disease: NTLA-3001 is a wholly owned, first-in-class CRISPR-mediated in vivo targeted gene insertion development candidate for the treatment of AATD-associated lung disease. It is designed to precisely insert a healthy copy of the SERPINA1 gene, which encodes the alpha-1 antitrypsin (A1AT) protein, with the potential to restore permanent expression of functional A1AT protein to therapeutic levels after a single dose. This approach seeks to improve patient outcomes, including eliminating the need for weekly intravenous infusions of A1AT augmentation therapy or lung transplant in severe cases.
  • Intellia is conducting IND-enabling activities for NTLA-3001 and plans to submit an IND or IND-equivalent filing in 2H 2023.
• NTLA-2003 for Associated Liver Disease: NTLA-2003 is a wholly owned, in vivo knockout development candidate for the treatment of AATD-associated liver disease. It is designed to inactivate the SERPINA1 gene responsible for the production of abnormal A1AT protein in the liver. This approach aims to halt the progression of liver disease and eliminate the need for liver transplant in severe cases.
  • Intellia is conducting IND-enabling activities for NTLA-2003, with the expectation of completing these activities by year-end 2023.

Ex Vivo Program Updates

Immuno-oncology and Autoimmune Diseases

• Intellia is advancing multiple preclinical programs, wholly owned and in collaboration with partners, utilizing its allogeneic platform for the treatment of immuno-oncology and autoimmune diseases. The Company’s proprietary allogeneic cell engineering platform is designed to avoid both T cell- and NK cell-mediated rejection, a key unsolved challenge with other investigational allogeneic approaches.
