E.5 End points |
E.5.1 | Primary end point(s) |
Maximum Tolerated Dose (MTD) and/or Recommended Phase 2 Dose (RP2D) of E7046 in combination with preoperative radiotherapy and chemotherapy. Safety/tolerability profile of E7046 in combination with preoperative radiotherapy and chemotherapy. |
Wyznaczenie maksymalnej tolerowanej dawki (maximum tolerated dose, MTD) lub zalecanej dawki w fazie II (recommended Phase 2 dose, RP2D) preparatu E7046 stosowanego w skojarzeniu z radioterapią i chemioterapią przedoperacyjną. Ocena bezpieczeństwa i tolerancji preparatu E7046 stosowanego w skojarzeniu z radioterapią i chemioterapią przedoperacyjną.
|
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
The maximum tolerated dose (MTD) is defined as 1 dose level below the dose level where ≥2 of 6 subjects experience a DLT. If ≤1/6 subjects in all dose cohorts experience a DLT, then an MTD will not have been reached. In this case, the RP2Dwill be selected based on integrated evaluation of safety, tolerability, clinical benefit, PK, and PD data, for all dose levels tested. |
Maksymalna tolerowana dawka (MTD) zdefiniowana jest jako wielkość dawki poprzedzająca taką, dla której u ≥2 z 6 uczestników wystąpiła DLT. Jeśli DLT wystąpi u ≤1/6 uczestników we wszystkich kohortach dawkowania, MTD nie zostanie osiągnięta. W takim przypadku RP2D zostanie dobrana na podstawie zintegrowanej oceny danych dotyczących bezpieczeństwa, tolerancji, korzyści klinicznej, PK i PD dla wszystkich przebadanych wielkości dawki. |
|
E.5.2 | Secondary end point(s) |
A pathological complete response (pCR) will be defined as having no viable cancer cells in the resected specimen. The pCR rate will be calculated as the number of patients with a pCR, divided by those who undergo a surgical procedure to resect the primary tumour (even if this is not successful). A circumferential resection margin (CRM) negative resection will be defined as having a complete macroscopic resection with microscopic tumor >1 mm from the radial. The CRM negative rate will be calculated as the total number of CRM negative patients, divided by the total number of patients in the trial. The pathological tumor regression grade (pTRG) will be assessed by Mandard TRG system: The MRI-confirmed tumor regression grade (mrTRG) and MRI-confirmed down staging in T stage will be assessed. Disease-free survival (DFS) will be defined as the time for treatment start to the date of the first documented disease occurrence, or date of death, whichever occurs first. |
Odpowiedź całkowicie potwierdzona histopatologicznie (pCR) zostanie zdefiniowana jako brak żywotnych komórek rakowych w wyciętej próbce materiału. Wskaźnik pCR zostanie obliczony jako liczba pacjentów z pCR, podzielona przez liczbę tych, którzy przejdą procedurę chirurgiczną resekcji pierwotnego guza (nawet jeśli nie zakończyła się ona powodzeniem). Potwierdzona histopatologicznie resekcji z ujemnym marginesem okrężnym (CRM) zostanie zdefiniowana jako całkowita resekcja makroskopowa z mikroskopowym guzem > 1 mm mierzonym promieniście. Wskaźnik negatywnych CRM zostanie obliczony jako całkowita liczba pacjentów CRM negatywnych, podzielona przez całkowitą liczbę pacjentów biorących udział w badaniu. Histopatologiczny stopień regresji guza (pTRG) będzie oceniony przez system Mandard TRG. Potwierdzony w badaniu MRI stopień regresji guza ( mrTRG) oraz potwierdzone w badaniu MRI zmniejszenie stopnia zaawansowania T będą również oceniane. Współczynnik przeżycia bez objawów choroby (DFS) zostanie zdefiniowany jako czas od rozpoczęcia leczenia do czasu wystąpienia pierwszych udokumentowanych objawów choroby, lub daty zgonu, którekolwiek nastąpi wcześniej.
