Brief Summary:
The purpose of this study is to determine the efficacy and the toxicities of the study drug PD0332991 in the treatment of patients with Stage IV non-small cell lung cancer with wildtype retinoblastoma protein (RB) and inactivated cyclin dependent kinase (CDK) N2A in the tumor.

Primary Outcome Measures :
  1. Tumor Response by Direct RECIST Measurement [ Time Frame: 6 months ]
    Response is a decrease in the sum of the longest diameters of the target lesions by more than 30% compared to the baseline.

Secondary Outcome Measures :
  1. Overall Survival [ Time Frame: 14 months ]
    Median overall survival

  2. Progression-free Survival [ Time Frame: 12 months ]
    Median progression-free survival.

  3. Plasma Levels [ Time Frame: 6 months ]
    Plasma levels of p16, phosphorylated RB and cyclin d1 in blood.

  4. Grade of Study Drug Toxicity [ Time Frame: 24 months ]
    The number of all toxicities and grades 3 and 4 (per CTCAE v3.0) toxicities that occured during the administration of the drug and during the follow up period.
