Study Details

Study Description

Brief Summary

TScan Therapeutics is developing cellular therapies across multiple solid tumors in which autologous participant-derived T cells are engineered to express a T cell receptor that recognizes cancer-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 LOH and expression of tumor antigens testing. These results will be used to determine if subjects meet the eligibility criteria for these parameters and could potentially be enrolled in a TScan clinical treatment study.

Condition or Disease Intervention/Treatment Phase
  • Diagnostic Test: Tumor and HLA Profiling

Detailed Description

This multicenter screening study will be conducted to determine a subject's tumor antigen expression profile, HLA genotype and HLA LOH for TScan sponsored clinical treatment study(s). No treatment intervention will occur as part of this screening study.

Subjects will be required to provide a buccal swab to assess their HLA status. If they are positive for certain types of HLA, they will return for a subsequent visit to provide a saliva sample to assess HLA loss of heterozygosity. In parallel, archival tissue (less than 6 months old) will be needed to assess for tumor antigen expression. If archival tissue is older than six months, a fresh tumor biopsy will be required at the time of the second visit.

If eligible, subjects will be referred to appropriate available interventional trial(s) at the discretion of the Investigator.

Outcome Measures

Primary Outcome Measures

  1. Frequency of subjects with TAA expression, HLA typing and HLA loss. [3 years]

    To identify subjects with Head and Neck, Cervical, Ovarian, Melanoma, Non-Small Cell Lung and HPV positive anogenital cancers that could potentially be eligible for the TScan Therapeutics clinical trials.

Eligibility Criteria

Criteria

Ages Eligible for Study:
18 Years and Older
Sexes Eligible for Study:
All
Accepts Healthy Volunteers:
No
Inclusion Criteria:
  1. Willing and able to provide written informed consent.

  2. Male or female aged ≥18 years at the time of signing the informed consent.

  3. Have one of the following histologically or cytologically confirmed locally advanced (unresectable) or metastatic solid tumor:

  • Head and neck cancer

  • Cervical cancer

  • Non-small cell lung cancer

  • Melanoma

  • Ovarian cancer

  • HPV positive anogenital cancers

  1. Willing to provide a buccal swab for HLA testing

  2. Willing to provide a saliva sample to use as a normal control for the LOH assay

  3. Have access to an FFPE tumor block that is <6 months old or is willing to provide a fresh core-needle biopsy.

Exclusion Criteria:
  1. 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.
