Brief summary

The purpose of this study is to find out whether romiplostim can help prevent low platelet counts caused by N8 or EFT chemotherapy, reduce the number of platelet transfusions required during chemotherapy, and prevent treatment delays due to low platelet counts.

Interventions

DRUGRomiplostim

Participants will receive weekly doses of romiplostim, beginning with cycle 4. The initial romiplostim dose will be 10 mcg/kg, and subsequent doses w ill vary based on chemotherapy regimen for a target of platelet count \> 75,000- 200,000/mcL. Participants will continue romiplostim until completion of MAP or D9803, as defined above. Maximum romiplostim dose is 10 mcg/kg. Participants will be followed until 6 months after the last dose of romiplostim.

Inclusion criteria

* Documented diagnosis of a primary solid tumor. Patients must have histological verification of malignancy at MSKCC. * Male and female patients aged 1-21 years with a primary solid tumor undergoing treatment with the pre-defined chemotherapy regimens of EFT, MAP, D9803. Prior to enrollment patient could have been undergoing induction therapy with a similarly myelosuppressive regimen as long as they will be continuing with EFT, MAP, D9803 at the time of study enrollment. * Patients undergoing treatment with MAP chemotherapy w ho have had ≥ 1 platelet transfusion during induction stage of treatment. * Total Bilirubin (sum of conjugated + unconjugated) ≤ 3 times institutional upper limit of normal (ULN) for age and ALT/AST ≤ 3 times institutional ULN for age. * Normal cardiac function: * Shortening fraction greater than or equal to 28% by echocardiogram OR Left ventricular ejection fraction (LVEF) greater than or equal to 50% on technetium- 99m pertechnetate radionuclide cineangiography (MUGA) or echocardiogram. * Screening ECG with corrected QT (QTc) interval of \< 470 msec. * Timing of cardiac assessment: We will utilize the most recent EKG/ECHO when assessing cardiac function. See section 9.0 for additional details. * Adequate renal function, defined as an estimated Creatinine Clearance or GFR \>40ml/min or an normal creatine for age (see below) Serum Creatinine by age: Age (years) \<6: Maximum Serum Creatinine (mg/dL), Male 0.8, Female 0.8 Age (years) 6 to \<10: Maximum Serum Creatinine (mg/dL), Male 1, Female 1 Age (years) 10 to \<13: Maximum Serum Creatinine (mg/dL), Male 1.2, Female 1.2 Age (years) 13 to \<16: Maximum Serum Creatinine (mg/dL), Male 1.5, Female 1.4 Age (years) \>16: Maximum Serum Creatinine (mg/dL), Male 1.7, Female 1.4 These threshold creatine values were derived from the Scwartz formula estimating GFR, utilizing child length and statured published by the CDC.

Exclusion criteria

History of uncontrolled arrhythmias, clinically significant electrocardiogram (ECG) abnormalities, active heart failure or pericardial disease. * Patients with current or prior venous thrombotic event or arterial thrombotic event at time of enrollment will be ineligible for this study. * Pregnant women/lactating mothers. * Patients unwilling to use effective contraception method, which includes abstinence. * Patients with an inability to return for follow-up visits or obtain follow-up studies required to assess toxicity to therapy.
