研究概览
简要总结
This study plans to detect the presence of trastuzumab by mass spectroscopy in relapsed posterior fossa ependymoma (PFEPN) tumor specimen pre-treated with a single dose of intrathecal (IT) trastuzumab, as well as to evaluate toxicity of intrathecal trastuzumab in combination with subcutaneous (subQ) Granulocyte-macrophage colony-stimulating factor (GM-CSF) in children with relapsed PFEPN

- •Monoclonal antibodies: At least three (3) half-lives of the antibody must have elapsed since the last dose of a monoclonal antibody (see Appendix I for list of half-lives)
- •Surgical resection: Must have fully healed from any surgical procedure to be safe for lumbar puncture according to treating neurosurgeon and at least 14 days should have elapsed since the surgical procedure.
- •Patients who in the opinion of the investigator may not be able to comply with the safety monitoring requirements of the study are NOT eligible for either Stratum.

研究组 & 干预措施
IT trastuzumab in combination with subQ GM-CSF
Experimental
Patients with localized recurrent PFEPN will be treated with IT trastuzumab in combination with GM-CSF to establish a maximum tolerated dosage. GM-CSF will be administered at 250 mcg/m2/dose subQ daily for three (3) days prior to the IT trastuzumab dose.
干预措施: Trastuzumab in combination with SubQ GM-CSF (Drug)
IT trastuzumab after subQ GM-CSF
Experimental
Patients with localized recurrent PFEPN will be treated with IT trastuzumab following 5-day course of subQ GM-CSF. Surgical resection should be planned (based on institutional surgical scheduling standards) for ideally 2-7 days after IT trastuzumab dosage.
干预措施: Trastuzumab after SubQ GM-CSF (Drug)
结局指标
主要结局
Stratum 1: Detection of trastuzumab in tumor following IT administration
时间窗: 2 weeks
The presence of trastuzumab will be measured as a binary (yes/no) outcome.
Stratum 2: Determine the Maximum Tolerated Dose (MTD) for IT trastuzumab in combination with fixed doses of subQ GM-CSF
时间窗: 1 month
The estimated MTD would be the highest dose at which 0/3 or 1/6 subjects experience a Dose Limiting Toxicity (DLT).
