NCT02255461

Brief Summary

This phase I trial studies the side effects and best dose of palbociclib isethionate in treating younger patients with central nervous system tumors that have grown, come back, or not responded to treatment. Palbociclib isethionate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

Outcome Measures

Primary Outcomes (13)

  • Maximum Tolerated Dose (MTD) of Palbociclib in Stratum I

    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.

    4 weeks

  • Maximum Tolerated Dose (MTD) of Palbociclib in Stratum II

    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.

    4 weeks

  • Number of Patients Who Experienced Dose Limiting Toxicities (DLTs)

    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.

    4 weeks

  • Single Dose Apparent Volume of Central Compartment (Vc/F)
