Screening patients with metastatic solid tumors for HLA and tumor antigen testing

Screening Study to Determine HLA Type, HLA Loss of Heterozygosity Status and Tumor Antigen Expression in Participants With Locally Advanced (Unresectable) or Metastatic Solid Tumors

Observational TScan Therapeutics, Inc. · NCT05812027

This study is testing whether patients with metastatic solid tumors can provide samples to see if they qualify for future treatments that target specific cancer-related markers.

What this trial studies

This observational screening study aims to collect samples from patients with metastatic solid tumors to assess their HLA genotype, loss of heterozygosity, and tumor-associated antigen expression. Participants will provide a buccal swab for HLA testing and may need to submit saliva and archival tissue samples for further analysis. The results will help determine eligibility for future TScan clinical treatment studies targeting specific cancer-associated antigens. No treatment will be administered during this screening phase.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with confirmed metastatic solid tumors such as head and neck cancer, cervical cancer, non-small cell lung cancer, melanoma, or ovarian cancer.

Not a fit: Patients currently undergoing anticancer therapy with curative intent or those without accessible tumor samples may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help identify patients who are eligible for innovative cellular therapies targeting their specific cancer types.

How similar studies have performed: Other studies utilizing HLA profiling and tumor antigen testing have shown promise in identifying suitable candidates for targeted therapies, indicating a potential for success in this approach.

* 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:
* Head and neck cancer
* Cervical cancer
* Non-small cell lung cancer
* Melanoma
* Ovarian cancer
* HPV positive anogenital cancers
* 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 FFPE tumor block that is \<8 months old or is willing to provide a fresh core-needle biopsy.

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.
