Study Status: Active, not recruiting
Recruit Status: Active, not recruiting
Study Type: Interventional

Official Title: A Phase II Trial to Assess the Activity and Safety of Palbociclib in Patients With Well and Moderately Differentiated Metastatic Pancreatic Neuroendocrine Tumors (pNET)

Brief Summary: A phase II trial to assess the activity and safety of PD0332991 in patients with well- and moderately-differentiated metastatic pancreatic neuroendocrine tumors (pNET) with overexpression of cell cycle markers (Cdk4 and/or phospho-Rb1 and/or cyclin D1)

Detailed Summary: The purpose of this study is to evaluate the activity and safety of PD0332991 in patients with well- and moderately-differentiated metastatic pancreatic neuroendocrine tumors (pNET) with overexpression of cell cycle markers (Cdk4 and/or phospho-Rb1 and/or cyclin D1)

Current Primary Outcome: Activity of palbociclib (PD0332991) considering objective response rate [ Time Frame: 20 months ]

Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Progression Free Survival [ Time Frame: Patients will be followed until disease progression, estimating around 12months ]
  • Time to Tumor Progression [ Time Frame: Patients will be followed until disease progression, estimating around 12 months ]
  • Duration of response [ Time Frame: Patients will be followed until disease progression, estimating around 12 months ]
  • Overall Survival [ Time Frame: Patients will be followed until death, estimating around 33 months ]
  • Number of participants with treatment-related adverse events as assessed by CTCAE v4.0 (Safety) [ Time Frame: Patients will be followed until disease progression estimating around 12 months ]
    Safety would be measured as Number of participants with treatment-related adverse events as assessed by CTCAE v4.0
  • Positive expression of tumor biomarkers (Cdk4, Cdk6, fosfo-Rb1, D1 cyclin, p53, Ki67) [ Time Frame: Positive expression of tumor biomarkers at baseline ]
    Percentage of neoplasique cells with positive expression of the following tumor biomarkers Cdk4, Cdk6, fosfo-Rb1, D1 cyclin, p53, Ki67 would be measured at baseline by immunohistochemistry


Original Secondary Outcome: Same as current
