|---|---|---|---|
| Primary | Maximum Tolerated Dose (MTD) of Palbociclib in Stratum I | 4 weeks | Rolling-6 design was used to estimate MTD. The MTD was empirically defined as the highest dose level at which six patients were treated with at most one patient experiencing a dose-limiting toxicity (DLT) and the next higher dose level had been determined to be too toxic. Stratum I consisted of less-heavily pre-treated patients. |
| Primary | Maximum Tolerated Dose (MTD) of Palbociclib in Stratum II | 4 weeks | Rolling-6 design was used to estimate MTD. The MTD was empirically defined as the highest dose level at which six patients were treated with at most one patient experiencing a DLT and the next higher dose level had been determined to be too toxic. Stratum II consisted of heavily pre-treated patients. |
| Primary | Number of Patients Who Experienced Dose Limiting Toxicities (DLTs) | 4 weeks | DLTs were defined as any of the following adverse events that were at least possibly related to palbociclib that occurred during the first 4 weeks of therapy regardless of expectedness. Hematologic DLTs included grade 3 neutropenia with fever and sepsis, grade 3 thrombocytopenia and/or requiring a platelet transfusion on 2 separate days within a 7-day period, or any grade 4 hematologic toxicity except lymphopenia. Non-hematologic DLTs included any grade 4 non-hematologic toxicity, any grade 3 non-hematologic toxicity with some exceptions (e.g., nausea and vomiting of \< 5 days; diarrhea and/or electrolyte disturbances which have not been maximally treated; AST/ALT elevation that returns to levels meeting eligibility criteria within 7 days of study drug interruption and does not recur upon restarting drug), or any grade 2 non-hematologic toxicity that persists for \> 7 days and is considered medically significant or sufficiently intolerable by patients requires treatment interruption. |
| Primary | Single Dose Apparent Volume of Central Compartment (Vc/F) | Up to day 3 | On day 1 of course 1, series blood samples for palbociclib pharmacokinetic studies were collected at pre-dose, 0.5, 1, 2, 4, 8 (±1), 10 (±0.5) optional, 24 (±4), 48 (±4) hours after the oral dose of palbociclib. Apparent volume of central compartment (Vc/F) was estimated using a non-compartmental method. |

Elimination rate constant (Ke) was estimated using a non-compartmental method. |

Half-life (t1/2) was estimated using a non-compartmental method. |
| Primary | Single Dose Apparent Oral Clearance (CL/F) | Up to day 3 | On day 1 of course 1, series blood samples for palbociclib pharmacokinetic studies were collected at pre-dose, 0.5, 1, 2, 4, 8 (±1), 10 (±0.5) optional, 24 (±4), 48 (±4) hours after the oral dose of palbociclib. Apparent oral clearance (CL/F) was estimated using a non-compartmental method. |
| Primary | Single Dose Area Under the Plasma Concentration Time Curve (AUC) | Up to day 3 | On day 1 of course 1, series blood samples for palbociclib pharmacokinetic studies were collected at pre-dose, 0.5, 1, 2, 4, 8 (±1), 10 (±0.5) optional, 24 (±4), 48 (±4) hours after the oral dose of palbociclib. Area under the plasma concentration time curve (AUC) was estimated using a non-compartmental method. |
| Primary | Steady State Apparent Volume of Central Compartment (Vc/F) | Up to day 22 | On day 21 of course 1, series blood samples for palbociclib pharmacokinetic studies were collected at pre-dose, 1, 2, 4, 8 (±1), 10 (±0.5) optional, and 24 (±4) hours after the dose. Apparent volume of central compartment (Vc/F) was estimated using a non-compartmental method. |
| Primary | Steady State Elimination Rate Constant (Ke) | Up to day 22 | On day 21 of course 1, series blood samples for palbociclib pharmacokinetic studies were collected at pre-dose, 1, 2, 4, 8 (±1), 10 (±0.5) optional, and 24 (±4) hours after the dose. Elimination rate constant (Ke) was estimated using a non-compartmental method. |

| Secondary | Number of Subjects With Objective Responses | Up to 2 years | Objective responses included complete response (CR) and partial response (PR). |
| Secondary | Association Between Neutropenia and Single Dose Palbociclib AUC | Up to approximately 4 weeks | Neutrophil count decreased adverse events observed in course 1 that were at least possibly attributable to palbociclib were included in analysis. Based on the highest toxicity grade reported, all participants, irrespective of their dose level or stratum, were combined and classified into three categories: 0 = no toxicity reported, 1 = grade 1 or 2, and 2 = grade 3 or 4. Association between neutrophil count decreased and single dose palbociclib AUC for all participants was examined. |
