Description

Summary

This study is open to adult patients with solid tumors who have a KRAS G12V mutation. This mutation is often found in non-small cell lung cancer (NSCLC), colorectal cancer (CRC), pancreatic ductal adenocarcinoma (PDAC) and other cancers. The study is for patients whose cancer has spread through the body and for whom previous treatments were not successful or treatment does not exist. Patients must also be positive for HLA-A*11:01. The purpose of this study is to find the best dose of AFNT-211 that is safe and can shrink tumors in patients. AFNT-211 is an investigational therapy and this is the first time that AFNT-211 is being administered to patients. AFNT-211 is an autologous T cell product which means that it is made from a patient's own T cells. These cells are engineered and grown to recognize the KRAS G12V protein on the cell surface of cancer cells. AFNT-211 is infused into patients after a short course of lymphodepleting chemotherapy. Patients will frequently visit the study site. The doctors there will regularly check the size of the cancer and the patient's health. They will also take note of any unwanted effects. Patients may continue in this study for as long as they benefit from the treatment.

Details

AFNT-211 is a cellular therapy consisting of autologous CD4+ and CD8+ T cells engineered to express a human leukocyte antigen-A (HLA-A)*11:01-restricted Kirsten rat sarcoma (KRAS) G12V-specific transgenic T cell receptor (TCR), the wildtype CD8α/β coreceptor, and a FAS-41BB switch receptor. AFNT-211 is being developed by Affini-T Therapeutics, Inc. (hereafter, "the Sponsor") for the treatment of patients with malignant solid tumors. The primary purpose of this study is to assess the safety and tolerability of AFNT-211 in subjects who are HLA-A*11:01 positive with advanced or metastatic cancers that harbor a KRAS G12V mutation, as well as determine the optimal biological dose (OBD) and recommended Phase II dose (RP2D) of AFNT-211 in this population. This study will also evaluate the preliminary anti-tumor activity of AFNT-211.
