简要总结
The purpose of this study is to find out what effects, good and/or bad, Palbociclib (Ibrance) (formerly known as PD0332991) has on the patient and on the liposarcoma.
Palbociclib is an investigational drug. An investigational drug is a medication that has not been approved for marketing by the Food and Drug Administration (FDA). Palbociclib blocks a protein called CDK4 which is part of a pathway in liposarcoma cells that is over-active. The investigators hope that blocking CDK4 will shut down this pathway in the liposarcoma cells and stop tumors from growing. Palbociclib is an oral medication.

入选标准
- •A diagnosis of liposarcoma confirmed at MSKCC. Because myxoid / round cell liposarcoma does not have significant CDK4 amplification, patients with this subtype are not eligible.
- •Metastatic and/or locally advanced or locally recurrent disease that is not surgically resectable, with evidence of disease progression, either clinically or radiographically, as determined by the investigator
- •All patients must have measurable disease as defined by RECIST 1.
- •Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded). Each lesion must be >10 mm when measured by CT, MRI or caliper measurement by clinical exam; or >20 mm when measured by chest x-ray. Lymph nodes must be > 15 mm in short axis when measured by CT or MRI.
- •A minimum of 1 prior systemic regimen for recurrent/metastatic disease. Note: This requirement does not apply to patients enrolled in the Expansion Cohort. The last dose of systemic therapy (include targeted therapies) must have been given at least 2 weeks prior to initiation of therapy. Patients receiving BCNU or mitomycin C must have received their last dose of such therapy at least 6 weeks prior to initiation of therapy.
- •Patients with brain metastasis that have been treated with definitive surgery or radiation and have been clinically stable for 3 months are eligible.
- •Age > or = 18 years.
- •ECOG performance status 0 or
- •Adequate organ and marrow function as defined below (ULN indicates institutional upper limit of normal):
- •Absolute neutrophil count ≥ 1.5x109/L Hemoglobin ≥ 9.0 g/dL WBC ≥ 3.0x109/L Platelets ≥ 100x109/L Total bilirubin ≤ 1.5 x ULN except for patients with known Gilbert syndrome AST(SGOT)/ALT(SGPT) ≤ 3 x institutional ULN Serum creatinine ≤ 1.5 x ULN or Creatinine Clearance > 50 mL/min (calculated by Cockcroft-Gault method)QTc interval ≤ 470 msec
- •Patients must not have current evidence of another malignancy that requires treatment.
- •The effects of Palbociclib on the developing human fetus at the recommended therapeutic dose are unknown. Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence). Women must not breast feed while on study.
- •Ability to understand and the willingness to sign a written informed consent document.
- •Ability to swallow intact Palbociclib capsules.
- •Patients" tumors must express Rb, as assessed using an historical biopsy sample if available or a newly obtained tumor sample. Samples must demonstrate ≥1+ staining for Rb. Patients' tumors must also have evidence of CDK4 amplification by FISH. Note: This does not apply to patients enrolled in the Expansion Cohort.
排除标准
- •Patients who have not recovered from adverse events of prior therapy to ≤ NCI CTCAEv4.0 Grade
- •Patients receiving any other investigational agents.
- •Patients who have received prior treatment with a selective CDK4 inhibitor
- •History of allergic reactions attributed to compounds of similar chemical or biologic composition to Palbociclib.
- •Uncontrolled intercurrent illness including, but not limited to, known ongoing or active infection, including HIV, active hepatitis B or C, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia (specifically, atrial fibrillation or ventricular dysrhythmias except ventricular premature contractions), or psychiatric illness/social situations that would limit compliance with study requirements.
- •Pregnant women and women who are breast-feeding.
- •Patients with a history of long-QT syndrome or documented family history of long-QT syndrome. Patients who must remain on drugs that prolong the QT interval.
- •Palbociclib is a substrate of CYP3A. Caution should be exercised when dosing Palbociclib concurrently with CYP3A inducers or inhibitors. Furthermore, patients who are taking concurrent medications that are strong inducers/inhibitors or substrates of CYP3A4 should be switched to alternative medications to minimize any potential risk. A list of CYP3A4 substrates, inducers and/or inhibitors is provided in Appendix B. The following medications with strong potential for interaction are not allowed: indinavir nelfinavir ritonavir clarithromycin itraconazole ketoconazole nefazodone saquinavir telithromycin carbamazepine phenobarbital phenytoin pioglitazone rifabutin rifampin St. John's wort Troglitazone
