|Official Title:||A Feasibility Study of Vorinostat (SAHA) Combined With Isotretinoin and Chemotherapy in Infants With Embryonal Tumors of the Central Nervous System|
- Dose-limiting toxicity of proposed vorinostat as graded by the National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 [ Time Frame: Up to 21 days ]
- Feasibility in terms of completing 3 courses of induction therapy [ Time Frame: Within 98 days ]Simon's two-stage optimal design will be used to assess feasibility.
- Prognostic value of histopathological classification of pediatric medulloblastoma by single-nucleotide polymorphism (SNP) analysis and gene expression analysis [ Time Frame: Up to 5 years ]Loss of heterozygosity (LOH) analysis and copy number analysis (CNA) will be performed using dChip SNP software (or R bioconductor package) for the paired samples. Association of copy number (and LOH) with gene expression data will be explored. Correlation analysis (Pearson or Spearman Correlation, as appropriate) will be used to estimate the strength of association between each SNP and expression signal. The multiplicity issue will be addressed through estimating the False Discovery Rate.
- Overall survival (OS) [ Time Frame: Up to 5 years ]Kaplan-Meier estimates of distributions of OS will be provided. If sample sizes allow, these Kaplan-Meier estimates will be produced separately for patients with MBs and PNETs.
- Predictive values of biological markers in CSF, plasma and urine in the context of a feasibility study [ Time Frame: Up to 5 years ]Frequency of the markers of interest present in this cohort will be provided and their associations with disease outcome will be explored. Similarly if sample size constraints make such analyses feasible, the associations between the markers of interest and clinical and demographic variables will be explored in a descriptive fashion.
- Progression-free survival (PFS) [ Time Frame: Up to 5 years ]Kaplan-Meier estimates of distributions of PFS will be provided. If sample sizes allow, these Kaplan-Meier estimates will be produced separately for patients with MBs and PNETs.
- Response rate of this approach in patients with measurable residual disease (primary site and/or metastatic sites) [ Time Frame: Up to 5 years ]Separate exact confidence interval estimates of objective responses following induction therapy will be constructed for patients with medulloblastomas (MBs) and PNETs. Cumulative incidence of objective responses as a function of course of therapy will also be provided.

I. To investigate the feasibility of administering vorinostat (SAHA) and isotretinoin for three days prior and concomitant with cisplatin based chemotherapy over three courses of induction chemotherapy.
II. To describe the toxicity of administering vorinostat (SAHA) and isotretinoin for three days prior and concomitant with cisplatin based chemotherapy over three courses of induction chemotherapy.
III. To investigate prognostic values of histopathological classification and biological markers in the context of a feasibility study.
I. To estimate the preliminary response rate of this approach in patients with measurable residual disease (primary site and/or metastatic sites).
II. To estimate disease specific progression-free and overall survival, in the context of a feasibility study.
III. To explore the predictive values of biological markers in cerebrospinal fluid (CSF), plasma, urine tumor material in the context of a feasibility study.
INDUCTION THERAPY: Patients receive vorinostat orally (PO) once daily (QD) and isotretinoin PO twice daily (BID) on days 1-4; vincristine sulfate intravenously (IV) on days 4, 11, and 18; cisplatin IV over 6 hours on day 4; cyclophosphamide IV over 1 hour on days 5-6; and etoposide phosphate IV over 1 hour on days 4-6. Treatment repeats every 21 days for 3 courses in the absence of disease progression or unacceptable toxicity. Patients also undergo peripheral blood stem cell (PBSC) harvesting after each course.
CONSOLIDATION THERAPY: Within 6 weeks (10 weeks if patient is re-staged) after completion of induction therapy, patients receive carboplatin IV over 2 hours and thiotepa IV over 2 hours on days 1-2. Patients also receive autologous PBSC rescue infusion over 6 hours on day 4. Treatment repeats every 28 days for 3 courses in the absence of disease progression or unacceptable toxicity. Beginning 3 weeks later, patients with M0 non-desmoplastic medulloblastoma also undergo conformal radiotherapy* to the tumor bed.
NOTE: *Patients with supratentorial primary tumors or metastatic disease undergo radiotherapy at the discretion of treating physician.
MAINTENANCE THERAPY: Beginning 4 weeks after completion of radiotherapy or immediately after completion of consolidation therapy, patients receive vorinostat PO QD on days 1, 3, 5, 6, 8, 10, 12, and 13 and isotretinoin PO BID on days 1-14. Treatment repeats every 28 days for up to 12 courses in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.
