E7 T-cell Receptor (TCR) -T Cell Induction Therapy for Locoregionally Advanced HPV-associated Cancers

The goal of this study is to determine the feasibility of administration of a single dose of E7 TCR-T cells as induction therapy prior to definitive treatment (chemoradiation or surgery) of locoregionally advanced HPV-associated cancers. The intent of E7 TCR-T cell treatment is to shrink or eliminate tumors and thereby facilitate definitive therapy and increase overall survival. This study seeks to determine 1) if E7 TCR-T cells can be administered without undue delay in definitive treatment, 2) the tumor response rate to E7 TCR-T cell treatment, and 3) the disease-free survival rate at 2 and 5 years. Participants will undergo an apheresis procedure to obtain T cells that will be genetically engineered to generate E7 TCR-T cells. They will receive a conditioning regimen, a single infusion of their own E7 TCR-T cells, and adjuvant aldesleukin. Participants will follow up to assess safety and determine tumor response and will return to their primary oncology team for definitive therapy.

This is a single-arm, single-cohort, single-center, feasibility study to determine the feasibility of E7 TCR-T cell induction therapy for locoregionally advanced human papillomavirus (HPV)-associated cancers (LAHPVC). Participants must have LAHPVC with HPV-16-positive cancer (tumor test) and the human leukocyte antigens (HLA)-A\*02:01 allele (blood test). Participants will undergo apheresis for generation of autologous, gene-engineered, E7 TCR-T cells. One week after apheresis, they will receive a non-myeloablative lymphocyte-depleting preparative regimen of cyclophosphamide and fludarabine. Conditioning will be followed by a single infusion of E7 TCR T cells and adjuvant high-dose aldesleukin. Participants will follow up 3 weeks and 6 weeks after treatment. Tumor response will be assessed by imaging studies at the 6-week time point. Participants will be referred back to their primary oncology team for definitive therapy after the 6-week assessment (or earlier if tumors do not appear to be responding). Participants will be followed to determine 2- and 5-year disease free survival.
