HLA Typing and Tumor Neoantigen Identification for a Phase I/II Study of Autologous T-Cell Receptor-Engineered T Cells (TCR-T) Reactive Against Cancer-specific Mutations in Subjects With Solid Tumors
HLA Typing and Tumor Neoantigen Identification for a Phase I/II Study of Autologous T-Cell Receptor-Engineered T Cells (TCR-T) Reactive Against Cancer-specific Mutations in Subjects With Solid Tumors
This is a data collection study, also referred to as a "screening" study; no investigational or standard therapy will be administered as part of this study. In order to identify subjects for the Phase I/II study, TCR001-201, patients with following histologically confirmed tumor types will be initially screened in this protocol for their somatic mutation and HLA type:
Subjects with a TCR match in the Alaunos TCR library will continue to be followed on this protocol and their clinical status will be monitored on an ongoing basis for eligibility, i.e., for progressive or recurrent disease, to enroll and receive TCR-T cell therapy on the Phase I/II study. Subjects will complete participation on this protocol when the subject enrolls on the Phase I/II study or if the subject dies.
This protocol will be used to perform and/or collect results from genetic mutation testing (e.g., Oncomine™ or similar genomic test performed at a CLIA-certified laboratory) and high resolution, human leukocyte antigen (HLA) class I and II typing from a CLIA-certified laboratory. This protocol will also collect subject clinical baseline characteristics, demographics, and cancer history. This protocol will be used to monitor subject disease status to identify candidates for enrollment onto the Phase I/II study as patients must have progressive or recurrent disease to be enrolled onto that protocol.
The subject's somatic mutation(s) and HLA type restriction combination will be examined against Alaunos' TCR library to determine if a TCR is available for that subject. Subjects without a TCR match will be discontinued from this protocol. If the subject's somatic mutation and HLA type restriction combination matched TCR is added to the Alaunos TCR library after the subject discontinues, the investigator may contact the subject to be re-screened for the study.
Subjects with a TCR match in the Alaunos TCR library will continue to be followed on this protocol and their clinical status will be monitored on an ongoing basis for eligibility, particularly progressive or recurrent disease, to enroll and receive TCR-T cell therapy on the Phase I/II study. Clinical status will be collected at enrollment and approximately every 3 months in conjunction with subjects' regularly scheduled standard of care visits. Subjects with a TCR match will complete participation on this protocol once they enroll in the Phase I/II study or if the subject dies.
Inclusion Criteria:
Patients who have previously received at least one line of standard systemic therapy for their advanced/metastatic cancer, and have either progressed, recurred or were intolerant to the previous treatment for one of the following cancer types:
Patients with previous tumor genomic testing performed at a CLIA-certified laboratory must be willing to disclose results. Patients that do not have previous tumor genomic testing must have a planned biopsy or resection as part of their standard of care (or archived tumor tissue available for genomic testing) or must provide a blood sample for circulating tumor DNA (liquid biopsy) testing. If prior genomic testing results or archival biopsy with sufficient tumor tissue are older than 6 months, a new tumor biopsy is required if being performed as standard-of-care. If re-biopsy is not feasible, a liquid biopsy must be performed to confirm previous test results.
Patients with previous high resolution, human leukocyte antigen (HLA) class I and II typing from a CLIA certified laboratory must be willing to disclose results. Patients that do not have previous typing results must be willing to provide a blood sample for this testing.
Patients must be able to provide written informed consent.
Patients must be age greater than or equal to 18 years.
Patients must have a clinical performance status of Eastern Cooperative Oncology Group (ECOG) of 0 or 1. Patients with an ECOG of 2 may be acceptable with Medical Monitor approval.
