Exclusion criteria
Exclusion criteria: 4.3 Exclusion criteria A potential subject who meets any of the following criteria will be excluded from participation in this study: 1. Distantly metastasized (stadium IVb) CSCC. 2. SCC localized in a mucosal surface (i.e. anus, vulva, penis or mucosal portion of lip). 3.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To determine the histopathological response rate to neo-adjuvant nivolumab and nivolumab plus ipilimumab at time of SOC (surgery ± RT).;Secondary Objective: Secondary objectives: - To establish whether short-term neo-adjuvant nivolumab w/wo ipilimumab is safe prior to standard of care surgery. - To compare recurrence free survival (RFS) at 2 years follow-up (FU) for patients responsive and non-responsive to neo-adjuvant ICI; - To compare overall survival (OS) at 2 years FU for patients responsive and non-responsive to neo-adjuvant ICI - To assess rate and type of AE (NCI CTCAE v.5.0) up to 2 years FU after SOC - To assess the response of potentially additional actinic keratosis (AK) to ICI at day 14, day 28 (at time of surgery) and during FU - To evaluate health related quality of life Exploratory objectives - To assess the (ex vivo) kinetics* of local and systemic immunological responses upon nivolumab or nivolumab plus ipilimumab and their correlation with clinical outcome. - To identify parameters to be exploited for future immunotherapeutic regimens ;Primary end point(s): The primary endpoint will be histopathological tumor response after neo-adjuvant ICI, defined as the proportion of viable tumor cells left in the resected specimen. Responses will be divided into histopathological complete response (pCR, no viable tumor cells), histopathological near complete response (near-pCR, =10% viable tumor cells) and histopathological partial response (pPR, =50% viable tumor cells). Pathological responses will be compared to responses assessed via clinical examination and imaging studies (FDG-PET and (functional)MRI) by RECIST 1.1 ;Timepoint(s) of evaluation of this end point: At time of surgery. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): - Rate and type of AE (NCI CTCAE v 5.0) prior to standard of care, and no significant delay (>1 week) or cancelation of SOC surgery due to immune-related toxicity. - RFS at 2 years FU of responders versus non-responders to neo-adjuvant ICI - OS at 2 years FU of responders versus non-responders to neo-adjuvant ICI - Rate and type of AE (NCI CTCAE v 5.0) up to 2 years FU after SOC - Clinical response of potentially additional AK surface areas after ICI identified by digital clinical photography on day 0, day 14, day 28 and during FU. - Quality of life as measured by EORTC QLQ-C30, H&N 35, EQ5D, CWS, IT questionnaire and the sexuality questionnaire Exploring the TME (early) upon ICI: - IHC and Bulk DNA & RNA sequencing of local tumor (when feasible also lymph node metastases) specimens at the aforementioned time points before and after start of ICI*, and its correlation to clinical outcome. - The development of an ex vivo functional assay for CSCC (Daniela Thommen platform) to predict individual ICI response. - The development of an ex vivo functional assay to challenge tumor specimens (and when feasible lymph node specimens) with ICI drugs at aforementioned time-points before and after start of neoadjuvant ICI*. - Single cell sequencing of tumor specimens before and after start of ICI*. - Hyperion Mass Cytometry of tumor specimens (and when feasible lymph node specimens) before and after start of ICI*. Endpoints for exploring systemic immunotherapy-related alterations: - Fresh blood flow cytometry (with a focus on suppressive cells as monocytes, neu-trophils) will be performed pre-, on and post-treatment* on all blood samples. - Heparin peripheral blood mononuclear cells (PBMCs) will be analysed pre-, on and post-treatment* on all blood samples for a quantitative and qualitative assessment of circulating adaptive immune cells. - Serum blood will be analysed for chemokines and cytokines, pre-, on and post-treatment* on all | — |
