An open label multicentre, phase I-II study with tumour molecular pharmacodynamics (MPD) evaluation and pharmacokinetics of PD-0332991 added to vemurafenib in patients suffering metastatic melanoma with BR.
The main objective is to establish the Maximum Tolerated Dose (MTD) of PD-0332991 when added to standard vemurafenib therapy (960 mg BID). The estimated MTD is defined as the dose of PD-0332991 combined with vemurafenib that will be associated with a prespecified proportion of patients experiencing a Dose-Limiting Toxicity (DLT), ie, 1/3.

|Official Title:||An Open Label Multicenter, Phase I-II Study With Tumor Molecular Pharmacodynamic (MPD) Evaluation and Pharmacokinetics of PD-0332991 in Patients Suffering Metastatic Melanoma With BRAFv600 Mutated and CDKN2A Loss and Expression of Rb and Treated by Vemurafenib|
|Study Start Date :||May 2014|
|Estimated Primary Completion Date :||November 2016|
|Estimated Study Completion Date :||August 2018|
Drug: PD- 0332991
PD-0332991 Inhibitor of cyclin-dependant kinase (CDK) 8 schedules will be evaluated PD-0332991 PO QD either at 25 mg, 50 mg, 75 mg, 100 mg, 125 mg, 150 mg, 175 mg and 200 mg
All patients will receive vemurafenib as background therapy ,bid at 720mg bid for the first group (during the first 2 cycle then 960 mg bid if good tolerance) and 960mg bid for all other patients
- Occurrence within the first 2 cycles of treatment of a DLT [ Time Frame: 42 Days ]
DLTs, serious adverse events and adverse events leading to treatment discontinuations will be determined as follows:
- Any grade 3 or more non-haematological toxicity excluding:
- Grade 3 asymptomatic increase in liver function tests (AST, ALT, ALP) reversible within 7 days for subjects without liver involvement, or grade 4 for subjects with liver involvement.
- Grade 3 vomiting if it is encountered despite adequate and optimal therapy (e.g. 5HT3 antagonists and corticosteroids).
- Grade 3 diarrhoeas if encountered despite adequate and optimal anti diarrhoea therapy.
- Confirmed grade 3 QTc prolongation (QTc >500 msec) that persists after correction of other possible causes such as electrolyte imbalance
- Grade 4 hyperlipidemia if it is encountered despite adequate and optimal therapy.
- Any grade 4 neutropenia of > 5 days duration, or febrile neutropenia lasting for more than 1 day.
- Grade 4 thrombocytopenia > 1 day, or grade 3 with bleeding.
- Efficacy [ Time Frame: 42 Days ]Occurrence of clinical benefit (defined as Complete Response (CR), Partial Response (PR) or stable disease (SD)) and progressive disease based on the best overall response which depends on the tumour evaluations assessed using RECIST at the end of each 2 cycles.
- 1 year survival rate [ Time Frame: 1 year ]survival
- Tolerance [ Time Frame: 6 months ]Occurrence of clinically significant changes in a laboratory parameter and/or vital signs judged to be related to the trial medication within the first 6 months.
- Pharmacodynamic [ Time Frame: 42 days ]
- Changes from baseline of ANC and platelet levels
- Efficiency on the cell-cycle machinery and proliferation (tumor sample)
- Induction of senescence: will be evaluated using the senescence β-Galactosidase assay (Cell Signaling Technology)
- Induction of apoptosis: will be performed using TUNEL staining with the ApopTag Peroxidase In Situ Apoptosis Detection Kit (Millipore).
