NCT05877599 | RECRUITING | Non-small Cell Lung Cancer

A Study of NT-175 in Adult Subjects With Unresectable, Advanced, and/or Metastatic Solid Tumors That Are Positive for HLA-A*02:01 and the TP53 R175H Mutation
Sponsor:

AstraZeneca

Brief Summary:

Phase I Study of NT-175, an autologous T cell therapy product genetically engineered to express an HLA-A\*02:01-restricted T cell receptor (TCR), targeting TP53 R175H mutant solid tumors.

Condition or disease

Non-small Cell Lung Cancer

Head and Neck Squamous Cell Carcinoma

Colorectal Carcinoma

Pancreatic Adenocarcinoma

Breast Cancer

Other Solid Tumors

Ovarian Cancer

Intervention/treatment

Autologous, engineered T Cells targeting TP53 R175H

Phase

PHASE1

Detailed Description:

This is a Phase 1, open-label, multicenter study to evaluate the safety and preliminary antitumor activity of NT-175 in HLA-A\*02:01 subjects with unresectable, advanced, and/or metastatic NSCLC, colorectal adenocarcinoma, HNSCC, pancreatic adenocarcinoma, ovarian cancer, breast cancer, or any other solid tumor histologies that are positive for the TP53 R175H mutation. Dose Escalation will investigate escalating doses of NT-175 in adult subjects with eligible solid tumor histologies and will evaluate the safety and MTD. Disease Histology Evaluation will further evaluate the safety and preliminary anti-tumor activity at or below the MTD in disease specific histologies and determine the RP2D. . Disease Cohort Expansion will further evaluate the preliminary anti-tumor activity and safety of NT-175 at the RP2D in disease specific settings.
