NOTE: Subjects with vitiligo, Grave’s disease, or psoriasis not requiring systemic treatment (within the past 2 years) can be enrolled 10.Active or prior documented inflammatory bowel disease (e.g., Crohn’s disease, ulcerative colitis) 11.History of primary immunodeficiency 12.History of allogenic organ transplant that requires the use of immunosuppressive drugs 13.Pregnant or breast-feeding women 14.Any condition that, in the opinion of the investigator, would interfere with evaluation of study treatment or interpretation of patient safety or study results 15.Known positive HIV status 16.Participation in another clinical study with an investigational product during the last 30 days. 17.Known hypersensitivity to the study drug, study drug classes, or study drug excipients. 18.Patients under guardianship or deprived of his liberty by a judicial or administrative decision or any condition (e.g., psychiatric illness/social/familial/geographical condition) that would limit compliance with study requirement or compromise the ability of the patients to give written informed consent

| Measure | Time frame |
|---|---|
| Main Objective: To evaluate the efficacy of bintrafusp alfa, measured by pathological response (PathR), given in a pre-operative setting.;Secondary Objective: 1/To evaluate the efficacy of bintrafusp alfa by alternative outputs: a)The pathological response, using alternative threshold of tumor cell death as compared to the one used for primary objective b)The response rate, using primary endpoint criteria, by PD-L1 status. c)The response rate, using primary endpoint criteria, by HPV status in cohort A. d)The clinical response, as measured by to RECIST v1.1. e)Assessment of disease-free survival (DFS), overall survival (OS), loco-regional disease-free survival (LR-DFS), distant disease-free survival (D-DFS) rates at 12, 18, 24 and 36 months after the surgery. 2/To evaluate the safety and tolerability profile of bintrafusp alfa 3/To evaluate the impact of inking the tumor margins during baseline endoscopy to avoid surgical plan changes putatively induced by tumor shrinking under therapy. EXPLORATORY OBJECTIVE: To evaluate the pharmacodynamics value of potential biomarkers comparing pre and post-treatment blood and tumor samples ;Primary end point(s): Rate of pathological response defined as tumor necrosis and/or giant cell/histolytic reaction to keratinous debris in =10% of tumor area. The measurement of pathological response will be performed under the responsibility of one pathologist per center as soon as the last patient has undergone his surgery (within 1 month). ;Timepoint(s) of evaluation of this end point: 10% of tumor area | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): The pathological response, using a threshold of 50% (PathR50), 70% (PathR70) and 90% (PathR90): will be considered as responders, the patients presenting 50% or more, 70% or more and 90% or more of tumor necrosis and/or giant cell/histolytic reaction to keratinous debris. b)The response rate, using primary endpoint criteria, by PD-L1 status using Combined Positive Score (CPS) thresholds of 1 and 20. CPS is the number of PD-L1 staining cells (tumor cells and immune cells) divided by the total number of viable tumor cells, multiplied by 100. Pre-treatment tissue specimens will be tested for PD-L1 expression and patients will be categorized as: oCPS <1: No PD-L1 expression oCPS =1: PD-L1 expression. Among this second group, patients will be further classified as =1CPS <20: Low PD-L1 expression and CPS =20: High PD-L1 expression. c)The response rate, using primary endpoint criteria, by HPV status defined by p16 staining in cohort A. Two categories will be defined: HPV- and HPV+ ( smokers =20 PY). HPV+ non-smoker or smoker <20 PY will be included in cohort B. d) The clinical response according to RECIST v1.1 on CT or MRI (same imaging than as baseline). e)Assessment of DFS, OS, LR-DFS, and D-DFS rates at 12, 18, 24 and 36 months after the surgery. 2)Evaluation of safety profile of bintrafusp alfa using the common toxicity criteria from the National Cancer Institute - Common terminology criteria for adverse events version 5.0 (NCI-CTCAE v5.0) 3)Evaluation of the impact of inking the tumor margins during baseline endoscopy in avoiding surgical plan changes putatively induced by tumor shrinking under therapy assessed by surgeon questionnaire ;Timepoint(s) of evaluation of this end point: - | — |
