Trial Outcomes & Findings for E7 TCR Cell Induction Immunotherapy for Stage II and Stage III HPV-Associated Oropharyngeal Cancer (NCT NCT04015336)

NCT ID: NCT04015336

Last Updated: 2022-02-24

Results Overview

Fraction of participants who can receive induction therapy with E7 T-Cell receptor (TCR) cells without failing the feasibility criteria with 95% confidence intervals. The feasibility criteria is defined as follows, 1) delivery of the E7 TCR T Cell induction therapy without an increase in tumor T or N stage between baseline and the last response assessment before referral for definitive treatment, 2) initiation of definitive therapy without a delay in treatment related to toxicity of the induction therapy, and 3) if any participant starts the conditioning regimen chemotherapy but does not receive the E7 TCR T Cells it will be considered a feasibility failure. Failure by one criterion will be scored as a feasibility failure.

Measure
Arm 1-3x10^10 E7 T-Cell Receptor (TCR) T Cells
Up to 3x10\^10 E7 T-Cell Receptor (TCR) T cells (based on the number of cells that can be generated in the shortened manufacturing process) will be administered intravenously over 20 to 30 minutes on day 0. E7 T-Cell Receptor (TCR): The dose of E7 T-Cell Receptor (TCR) T cells will be 3 x 10\^10 TCR+ T cells (unless fewer cells are generated) administered once.

PRIMARY outcome

Timeframe: 3 months

Population: Data was not collected for this outcome measure. This outcome measure was not done because the single enrolled participant signed consent and was later deemed a screen failure, thus was unable to receive induction therapy with E7 TCR cells. Participant was not treated and the study was terminated due to logistical challenges.

Fraction of participants who can receive induction therapy with E7 T-Cell receptor (TCR) cells without failing the feasibility criteria with 95% confidence intervals. The feasibility criteria is defined as follows, 1) delivery of the E7 TCR T Cell induction therapy without an increase in tumor T or N stage between baseline and the last response assessment before referral for definitive treatment, 2) initiation of definitive therapy without a delay in treatment related to toxicity of the induction therapy, and 3) if any participant starts the conditioning regimen chemotherapy but does not receive the E7 TCR T Cells it will be considered a feasibility failure. Failure by one criterion will be scored as a feasibility failure.

Outcome measures

Outcome data not reported

OTHER_PRE_SPECIFIED outcome

Timeframe: Date treatment consent signed to date off study, approximately 9 days.

Population: This outcome measure was not done because the participant was not evaluable for toxicity since the toxicity evaluation begins at the time of induction therapy. The participant was never treated with induction therapy.

Here is the number of participants with serious and non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.
