Intellia Therapeutics Announces U.S. FDA Acceptance of Investigational New Drug Application for NTLA-5001, its CRISPR/Cas9-Engineered TCR-T Cell Candidate for Acute Myeloid Leukemia
- NTLA-5001 is Intellia’s first ex vivo candidate using its proprietary cell engineering process for the treatment of cancer to enter clinical study
- NTLA-5001 targets Wilms’ Tumor 1 (WT1), an overexpressed intracellular antigen on many hematologic malignancies and solid tumors
- Initiation of patient screening in Phase 1/2a study of NTLA-5001 expected by year-end
“The FDA’s acceptance of our IND for NTLA-5001 is an important milestone in our pursuit of developing advanced cell therapies utilizing Intellia’s proprietary engineering platform to treat patients with cancer. NTLA-5001 is our first wholly-owned ex vivo candidate to enter the clinic, and we expect to initiate this first-in-human study in adults with AML by year-end. Our treatment strategy is to leverage CRISPR/Cas9 genome editing technology to create next-generation engineered immune cells with the potential to attack cancer cells more effectively and safely than previously developed cell therapies,” said Intellia President and Chief Executive Officer
The Phase 1/2a study will evaluate the safety, tolerability, cell kinetics and anti-tumor activity of a single dose of NTLA-5001 in adults who have detectable AML after having received standard first-line therapy. The study will contain a dose escalation and expansion phase, with up to 54 participants. The dose-escalation phase of the study will include two independent arms of up to three cohorts: Arm 1 will consist of adults with AML with lower disease burden, defined as those with less than 5% AML blasts in bone marrow, while Arm 2 will consist of adults with AML with higher disease burden, defined as those greater than or equal to 5% AML blasts in bone marrow. Once a dose is identified in each arm, two expansion cohorts will be opened for further safety assessment. More information about the study will be available at clinicaltrials.gov.

About Acute Myeloid Leukemia
Acute myeloid leukemia (AML) is a cancer of the blood and bone marrow that is rapidly fatal without immediate treatment. It is the most common type of acute leukemia in adults, with more than 20,000 estimated new cases in 2020. Despite currently available treatments for AML, the five-year overall survival rate for patients remains less than thirty percent. AML, along with other cancer types, is often characterized by overexpression of the Wilms’ Tumor 1 (WT1) antigen.
NTLA-5001 is a CRISPR/Cas9-engineered T cell receptor (TCR)-T cell therapy in development for the treatment of all genetic subtypes of acute myeloid leukemia (AML). This autologous cell therapy candidate is designed for AML patients with the HLA-A*02:01 allele whose tumors carry the Wilms’ Tumor 1 (WT1) antigen, which is widely overexpressed in AML and other cancers. NTLA-5001 is Intellia’s first wholly-owned ex vivo therapeutic candidate, developed using its proprietary cell engineering platform for the treatment of cancer. Based on preclinical results, Intellia believes its proprietary cell engineering platform will result in a pipeline of more efficacious and safer cell-based cancer therapies.
