E.5 End points |
E.5.1 | 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).
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | 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
