CAMBRIDGE, Mass., Oct. 06, 2021 (GLOBE NEWSWIRE) -- Intellia Therapeutics, Inc. (NASDAQ:NTLA), a leading clinical-stage genome editing company focused on developing curative therapeutics using CRISPR/Cas9 technology both in vivo and ex vivo, today announced the authorization of its Clinical Trial Application (CTA) by the New Zealand Medicines and Medical Devices Safety Authority (MEDSAFE) to initiate a Phase 1/2 study evaluating NTLA-2002 for the treatment of adults with hereditary angioedema (HAE). HAE is a 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. NTLA-2002 is a systemically administered single-dose CRISPR/Cas9-based therapeutic candidate designed to inactivate the target gene Kallikrein B1 (KLKB1) to permanently reduce plasma kallikrein activity and thus prevent HAE attacks.
"We look forward to initiating this year our first-in-human study of NTLA-2002 for people living with HAE, a debilitating disorder that causes frequent, potentially life-threatening attacks," said Intellia President and Chief Executive Officer John Leonard, M.D. "We believe NTLA-2002 has the potential to be a curative therapy for patients with HAE by providing continuous suppression of plasma kallikrein activity following a single dose and eliminating the significant treatment burden associated with currently available HAE therapies. This study of NTLA-2002 leverages early insights from our ATTR amyloidosis program, where we established proof-of-concept for our modular in vivo genome editing platform with interim Phase 1 data earlier this year. The NTLA-2002 program represents the second systemic in vivo CRISPR genome editing therapy candidate to enter human clinical trials."
The Phase 1/2 study will evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of NTLA-2002 in adults with Type I or Type II HAE. This includes the measurement of 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. More information about the study will be available at clinicaltrials.gov.
Beyond New Zealand, Intellia is submitting additional regulatory applications in other countries as part of its ongoing, multi-national development approach for NTLA-2002.
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.
Based on Nobel Prize-winning CRISPR/Cas9 technology, NTLA-2002 is potentially the first single-dose treatment 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 Intellia Therapeutics
Intellia Therapeutics, a leading clinical-stage genome editing company, is developing novel, potentially curative therapeutics using CRISPR/Cas9 technology. To fully realize the transformative potential of CRISPR/Cas9, Intellia is pursuing two primary approaches. The company's in vivo programs use intravenously administered CRISPR as the therapy, leveraging proprietary delivery technology to enable 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 CRISPR/Cas9 to create new classes of genetic medicine.
