E.2.3.1 | Full title, date and version of each sub-study and their related objectives |
Des biopsies tumorales (en option) au screening et au jour 21 du Cycle 1 peuvent être collectées. Une fois prélevés, les échantillons peuvent être analysés par IHC et une analyse de l'expression génique peut être réalisée pour identifier l'activité pharmacodynamique du PD-0332991 chez les patients atteints de GIST.
Comme il s'agit d'un domaine de recherche actif, plusieurs biomarqueurs peuvent être analysés s’ils sont justifiés par les résultats des activités de recherche internes ou externes.
Chaque échantillon sera envoyé au promoteur. |

E.5 End points |
E.5.1 | Primary end point(s) |
Efficacy is assessed based on 4-month non progression. Non progression is defined as complete or partial response (CR, PR) or stable disease (SD), using the Response Evaluation Criteria in Solid Tumors (RECISTv1.1). Non-progression rate will be calculated as the number of alive and progression free patients divided by the number of eligible and assessable patients for the efficacy analysis.
Eligible and assessable populations are described in corresponding section of protocol.
As recommended by RECIST v1.1, all claimed response will be centrally reviewed by an expert of the study. The results of the centralized radiological review will be used for the analysis of the primary endpoint. |
|
E.5.2 | Secondary end point(s) |
-Objective response is defined as complete response (CR) or partial response (PR) according to RECIST v1.1.
-Progression-free survival is defined as the time from the first administration of treatment to progression (as per RECIST v1.1) or death of any cause, whichever occurs first
- Overall survival is defined as the time from the first administration of treatment to death.
- Progression will also be assessed using CHOI criteria
- Safety of PD-0332991 will be assessed by the Common Terminology Criteria for Adverse Events (CTCAE), v4.0 |
