简要总结
To comprehensively describe the molecular profile of the tumour ecosystem of cutaneous squamous cell carcinoma (CSCC) patients treated with neoadjuvant immunotherapy using single-cell sequencing and bulk genomic profiling.
详细描述
The purpose of this study is to comprehensively assess the molecular profile of the tumour ecosystem of CSCC patients who receive immunotherapy in the neoadjuvant curative setting, in order to identify molecular mechanisms facilitating treatment response and resistance and to identify molecular markers for disease monitoring. Patients who receive immunotherapy for the neoadjuvant management of CSCC will be invited to participate in this translational research study during their treatment journey to provide tumour tissue (fresh and formal-fixed paraffin-embedded, FFPE) and blood samples before and after exposure to immunotherapy.
This study has primarily a translational research objective with the clinical component conducted as a prospective, single-centre, single-arm, open label study.

For clarity, exceptions include other non-melanoma skin cancer that has undergone potentially curative therapy, or in-situ cervical carcinoma or in-situ prostate cancer with non-detectable prostate specific antigen or any other tumour that has been treated, and the patient is deemed to be in complete remission for at least 2 years prior to enrolment.

- •Receipt of live vaccine (including attenuated) within 30 days of first study treatment.
- •Prior transplant recipient (corneal transplant patients are eligible).
- •Prior PD-L1/PD-1 inhibitor exposure for the same lesion as enrolment.
- •Squamous cell carcinoma of unknown primary (those with presumed clinical assessment of CSCC are eligible).
- •Any anticancer treatment other than radiation therapy (such as chemotherapy, targeted systemic therapy, imiquimod, photodynamic therapy), either investigational or standard of care, within 30 days of the initial administration of cemiplimab or planned to occur during the study period.
- •History of documented allergic reactions or acute hypersensitivity reaction attributed to antibody treatments.
- •Patients with allergy or hypersensitivity to cemiplimab or to any of the excipients must be excluded.
- •Institutionalised patients by order of judicial or administrative authority.
- •Not willing to comply with all study related procedures, particularly consent for collection of tumour and blood samples and imaging, at all protocol specified time points.
