Clinical Trial Summary

The purpose of this study is to find out how safe and effective treatment with a new combination of drugs, vorinostat and etoposide, is in treating cancer. The medication etoposide is a standard medication used in the treatment of cancer in children. Vorinostat is an experimental drug which targets a protein(s) that control the way cancer cells grow and divide. Vorinostat is approved by the FDA in adults with certain cancers but not approved yet in children. There are two parts to this study. In the first part of this study, the phase I portion, a safe dose of the combination, vorinostat and etoposide. The goal of second part of this study, the phase II portion, is to see how effective the combination of vorinostat and etoposide is in treating cancer.

• Radiation therapy (XRT): > or = to 2 weeks must have elapsed for local XRT (small port); > or = to 6 months must have elapsed if prior radiation to > or = to 50% of the pelvis or if other substantial bone marrow irradiation, including total body irradiation.
• Patient must be able to swallow capsules.
• Patient must have an available archival/pre-treatment block or fresh tumor biopsy for molecular profiling to be performed.

Exclusion Criteria:

• A patient meeting any of the following criteria is not eligible to participate in this

study:

• Patients currently participating or has participated in a study with an investigational compound or device within 4 weeks of initial dosing with study drugs.
• Patients with a prior history of treatment with HDAC inhibitors ( e.g. SNDX-275/entinostat, LAQ-824, LBH589, PXD-101/belinostat, etc). Patients who have received Valproic acid will be excluded from this study.
• Patients with non CNS primary tumors who have known brain metastases or symptomatic CNS disease (e.g. cranial nerve abnormalities) without cytologic abnormality in the CSF should be excluded from this clinical trial because of their poor prognosis and known propensity for the development of progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. Patients with metastatic CNS tumors will not be excluded from enrollment on this study in the phase I component only.
• Patients who have undergone prior autologous stem cell transplantation or allogeneic transplantation.
• Uncontrolled intercurrent illness or circumstances that could limit compliance with the study requirements including, but not limited to: ongoing or active bacterial or fungal infection, acute or chronic graft versus host disease, symptomatic congestive heart failure, cardiac arrhythmia, or psychiatric illness/social situations.
• Patients who are pregnant or breastfeeding, or expecting to conceive within the projected duration of the study. Because there is an unknown but potential risk for adverse events in nursing infants secondary to treatment of the mother with vorinostat, lactating patients will be excluded from this study.
• Patients known to be Human Immunodeficiency Virus (HIV)-positive.
• Patients with known hypersensitivity to the components of the study drugs or their analogs.
• Patients with symptomatic ascites or pleural effusion. A patient who is clinically stable following treatment for these conditions is eligible.
• Patients who are at the time of signing informed consent, a regular user of any illicit drugs, substance abuser or who have a recent history of drug or alcohol abuse.
• Patients with a known history of Hepatitis B or C.
• Patients who have a history of gastrointestinal surgery or other procedures that might in the opinion of the investigator, interfere with the absorption or swallowing of the study drug.
• Patients who are unable to take or tolerate oral medications on a continuous basis.
• Patients with a history of a prior malignancy who have undergone potentially curative therapy with no evidence of that disease for five years or patients, who are deemed low risk for recurrence by his/her treating physician are permitted to enroll.

Intervention

Drug:
• Vorinostat and Etoposide
Patients will be assessed in 3-week cycles. Escalating doses of vorinostat will be administered orally on a daily x 4 schedule in combination with a fixed dose of etoposide. Etoposide will be administered intravenously daily x 3 days. Cohorts of 3-6 patients will be treated with vorinostat and etoposide. In the phase II component, patients will be treated at the RP2D established in the Phase I component of the study, which was found to be 270 mg/m2/dose of Vorinostat and 100 mg/m2/dose of Etoposide.
