NT-175 is an investigational monoclonal antibody being developed by AstraZeneca PLC for the treatment of advanced solid tumors, including non-small cell lung cancer. It is designed to target cancers that carry a specific biomarker profile: positivity for HLA-A*02:01 and the TP53 R175H mutation. NT-175 is currently in Phase 1 clinical development.

What is NT-175 used for in non-small cell lung cancer?

NT-175 is being studied for use in non-small cell lung cancer and other advanced malignancies that are positive for HLA-A*02:01 and the TP53 R175H mutation. It is an investigational therapy and has not been approved for any indication. Treatment is limited to adult participants enrolled in its ongoing clinical trial.

Who makes NT-175?

NT-175 is being developed by AstraZeneca PLC, which trades on the Nasdaq under the ticker AZN. AstraZeneca is the sponsor of the ongoing Phase 1 study of NT-175 in patients with advanced malignancies, including non-small cell lung cancer, that are positive for HLA-A*02:01 and the TP53 R175H mutation.

What phase is NT-175 in?

NT-175 is in Phase 1 clinical development. It is an investigational monoclonal antibody and has not been approved by the FDA or any other regulatory agency. The single ongoing Phase 1 trial is currently recruiting adult participants with advanced malignancies, including non-small cell lung cancer, who test positive for HLA-A*02:01 and the TP53 R175H mutation.

What clinical trials is NT-175 in?

NT-175 is being evaluated in one Phase 1 trial, NCT05877599, titled A Study of NT-175 in Adult Participants With Advanced Malignancies That Are Positive for HLA-A*02:01 and the TP53 R175H Mutation. The trial is recruiting in the United States with a planned enrollment of 45 participants and is an uncontrolled, non-randomized study.

Who is eligible for the NT-175 clinical trial?

The NCT05877599 trial enrolls adults aged 18 years and older of any sex who have advanced malignancies positive for HLA-A*02:01 and the TP53 R175H mutation. Eligible tumor types include non-small cell lung cancer, head and neck squamous cell carcinoma, colorectal carcinoma, pancreatic adenocarcinoma, breast cancer, ovarian cancer, other solid tumors, and myeloid neoplasms such as AML and MDS.
