A Phase II Trial of T Cell Receptor Gene Therapy Targeting Human Papillomavirus ( HPV) 16 E7 for HPV-Associated Cancers
Summary
This is a phase II clinical trial to assess the clinical activity of immunotherapy with E7 TCR-T cells for metastatic HPV-associated cancers. HPV-associated cancers in include cervical, throat, penile, vulvar, vaginal, anal, and other cancers. Participants will receive a conditioning regimen, E7 TCR-T cells, and aldesleukin. Clinical response to treatment will be determined.
Detailed description
This study will determine the tumor response rate for the treatment of HPV-associated cancers with E7 TCR-T cells. E7 TCR-T cells are autologous gene-engineered T cells that target HPV16 E7 through a T cell receptor (TCR). E7 is an HPV oncoprotein that is present in HPV-associated cancers. Participants must have the HLA-A\*02:01 allele, which is required for tumor targeting by the E7 TCR. Treatment consists of a conditioning regimen (cyclophosphamide and fludarabine), a single infusion of E7 TCR-T cells, and adjuvant aldesleukin. Tumor response rate and response duration will be determined. Safety data will also be collected.
Arms & interventions
- BiologicalE7 TCR-T cells
Participants will receive a conditioning regimen consisting of cyclophosphamide and fludarabine. E7 TCR-T cells will be administered as a single intravenous infusion.
- DrugAldesleukin
Within 24 hours after E7 TCR-T cell infusion, aldesleukin 720,000 IU/kg IV every eight hours will be administered for up to six doses. Aldesleukin dosing will be stopped for aldesleukin-related grade 3 or greater toxicity other than flushing, fever, chills, or hemodynamic changes (tachycardia or hypotension) that respond to crystalloid infusion. Aldesleukin may also be stopped at any time at investigator discretion.
