Trial Outcomes & Findings for Therapeutic Effects of Epstein-Barr Virus Immune T-Lymphocytes Derived From a Normal HLA-Compatible Or Partially-Matched Third-Party Donor in the Treatment of EBV Lymphoproliferative Disorders and EBV-Associated Malignancies (NCT NCT01498484)

NCT ID: NCT01498484

Last Updated: 2022-10-21

Results Overview

The ORR is defined as percentage of participants with best overall response of complete remission/response (CR) or partial remission/response (PR) based on investigator's assessment. For participants with clinically and/or radiologically evident EBV LPD or malignancies, CR is complete resolution of all clinical and radiologic evidence of lymphoma, confirmed by biopsy of the affected tissues when indicated, lasting for at least 3 weeks following completion of a cycle of tabelecleucel; and PR is a 50 % or greater reduction in the size of all lymphomatous lesions as determined by computed tomography (CT) or magnetic resonance imaging (MRI) measurements of tumor volume, which was maintained for at least 3 weeks following completion of a cycle of tabelecleucel. For participants without clinically and/or radiologically evident tumors with increasing levels of EBV DNA, CR is clearance of EBV without subsequent development of EBV+ LPD; and PR is at least a 10-fold decrease in EBV DNA levels.

HCT EBV+ PTLD R/R Rituximab
Participants with Epstein-Barr virus positive (EBV+) posttransplant lymphoproliferative disorders (PTLD) hematopoietic cell transplant (HCT) who were relapse/refractory (R/R) to rituximab received IV infusion of tabelecleucel 2 × 10\^6 T-cells/kg on Days 1, 8, and 15 and were observed for 3 weeks. After the observation period, additional courses (2 courses) may have been provided in the absence of disease progression or unacceptable toxicity.

PRIMARY outcome

Timeframe: From Day 1 through 65.3 months after Day 1 dose

Population: Full analysis set included all participants who received at least one dose of tabelecleucel.

The ORR is defined as percentage of participants with best overall response of complete remission/response (CR) or partial remission/response (PR) based on investigator's assessment. For participants with clinically and/or radiologically evident EBV LPD or malignancies, CR is complete resolution of all clinical and radiologic evidence of lymphoma, confirmed by biopsy of the affected tissues when indicated, lasting for at least 3 weeks following completion of a cycle of tabelecleucel; and PR is a 50 % or greater reduction in the size of all lymphomatous lesions as determined by computed tomography (CT) or magnetic resonance imaging (MRI) measurements of tumor volume, which was maintained for at least 3 weeks following completion of a cycle of tabelecleucel. For participants without clinically and/or radiologically evident tumors with increasing levels of EBV DNA, CR is clearance of EBV without subsequent development of EBV+ LPD; and PR is at least a 10-fold decrease in EBV DNA levels.

Population: Full analysis set included all participants who received at least one dose of tabelecleucel. Participants who were lost to follow-up or still alive were censored on the last known-to-be-alive date.

The OS is defined as the time from the first dose of tabelecleucel to the date of death due to any cause. The OS was estimated using Kaplan-Meier method. Participants who were lost to follow-up or still alive were censored on the last known-to-be-alive date.

SECONDARY outcome

Timeframe: From Day 1 through 65.3 months after Day 1 dose

Population: Full analysis set included all participants who received at least one dose of tabelecleucel. Participants who achieved CR or PR were analyzed for this outcome measure.

The TTR is defined as the time from the date of the first dose of tabelecleucel to the date of a PR or CR, whichever occurred first. For participants with clinically and/or radiologically evident EBV LPD or malignancies, CR is defined as complete resolution of all clinical and radiologic evidence of lymphoma, confirmed by biopsy of the affected tissues when indicated, lasting for at least 3 weeks following completion of a cycle of tabelecleucel; and a PR is defined as a 50 % or greater reduction in the size of all lymphomatous lesions as determined by CT or MRI scan measurements of tumor volume, which was maintained for at least 3 weeks following completion of a cycle of tabelecleucel. For participants without clinically and/or radiologically evident tumors with increasing levels of EBV DNA, CR is defined as clearance of EBV without subsequent development of EBV+ LPD; and PR is defined as at least a 10-fold decrease in EBV DNA levels.
