Summary
Brief summary (as posted)
TScan Therapeutics is developing cellular therapies across multiple solid tumors in which autologous T cells are engineered to express a T cell receptor that recognizes tumor-associated antigens presented on specific Human Leukocyte Antigen (HLA) molecules. The purpose of this screening study is to collect samples to conduct HLA genotyping, HLA Loss of Heterozygosity (LOH) assessment, and expression of Tumor-associated Antigens (TAA) testing. These results will be used to determine if participants meet the eligibility criteria for these parameters and could potentially be enrolled in a TScan clinical study.

Show eligibility criteria text
Inclusion Criteria: * Willing and able to provide written informed consent. * Male or female aged ≥18 years at the time of signing the informed consent. * Have one of the following histologically or cytologically confirmed locally advanced (unresectable) or metastatic solid tumor for which the Sponsor has an associated clinical study: * Head and neck cancer * Cervical cancer * Non-small cell lung cancer * HPV positive anogenital cancers * Sarcoma * Other cancers with a reasonable likelihood of expressing 1 or more antigens included in a TScan clinical trial, following approval by the TScan Medical Monitor or their delegate. * Willing to provide a buccal swab for HLA testing * Willing to provide a saliva sample to use as a normal control for the LOH assay * Have access to an adequate FFPE tumor block that is \<8 months old or is willing to provide a fresh core-needle biopsy from a location deemed safe by the treating medical team. Exclusion Criteria: • Participants undergoing anticancer therapy with curative intent such as tumor surgical resection with or without neoadjuvant/adjuvant therapy, or definitive chemoradiation, unless they have locoregionally advanced disease and are expected to have a high risk of relapse after their curative intent therapy as determined by the treating investigator.
