More on NTLA's Gene-Editing Candidate NTLA-2002

NTLA-2002 is Intellia’s investigational single-dose CRISPR/Cas9 gene-editing therapy, which is being developed as a one-time cure for HAE. It is a rare genetic condition marked by severe inflammatory attacks in various body organs and tissues, which can be painful and even life-threatening.

Despite the current treatment options that require chronic administration for disease control, HAE attacks still occur. NTLA-2002 aims to prevent HAE attacks by suppressing the plasma kallikrein activity.

Previously, data from the ongoing phase I/II study showed that treatment with a single-dose of NTLA-2002 can lead to a complete response – no more attacks as well as no further treatment required.

In June, the company announced encouraging long-term data from the phase I portion of its early to mid-stage study evaluating NTLA-2002 for treating HAE.

Studies on NTLA's Another Candidate NTLA-2001 Progressing Well

Intellia is collaborating with Regeneron Pharmaceuticals REGN for the development of its investigational in vivo genome-editing candidate, NTLA-2001.

NTLA-2001 is part of the company’s co-development and co-promotion agreement with Regeneron. While NTLA is the lead party in the deal for NTLA-2001, REGN shares 25% of the development costs and commercial profits.

NTLA-2001 is being studied for two indications, transthyretin (ATTR) amyloidosis with polyneuropathy (ATTRv-PN) and ATTR amyloidosis with cardiomyopathy (ATTR-CM).

The ongoing phase III MAGNITUDE study is evaluating NTLA-2001 to treat ATTR amyloidosis with cardiomyopathy. If the data from the MAGNITUDE study is found to be positive, it will enable global regulatory filings for NTLA-2001.

Intellia also plans to initiate a pivotal phase III study evaluating NTLA-2001 as a single-dose treatment in ATTRv-PN by 2024-end.
