Temozolomide,Thiotepa and Carboplatin With Autologous Stem Cell Rescue Followed by 13-cis-retinoic Acid in Patients With Recurrent/Refractory Malignant Brain Tumors

• Status: Completed
• Trial end date: 2017-12-30
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to:

Find out how safe and effective (by monitoring the good and/or bad effects) treatment with high dose temozolomide, thiotepa and carboplatin with stem cell rescue followed by 13-cis-retinoic acid has on children and adolescents with recurrent/refractory brain tumors

Find out how the body uses 13-cis-retinoic acid by studying the your blood levels and proteins in the blood that break down the 13-cis-retinoic acid

Determine how well 13-cis-retinoic acid penetrates into the spinal fluid.

• Phase: Phase 2

Criteria

Inclusion Criteria:

1. Patients with recurrent or refractory medulloblastoma/PNET, CNS germ cell tumors, ependymomas, AT/RT, high grade glioma and other malignant brain tumors. Brainstem gliomas are eligible if residual disease is < 1.5cc and if the patient is off decadron.

2. Patients must have recurrent or refractory disease following at least one prior course of therapy and must have minimal residual disease defined as < 1.5 cm2 of enhancement. Patients with + CSF cytology, linear or fine nodular leptomeningeal disease are eligible.

3. Adequate hematologic, renal, liver, and cardiac function as demonstrated by laboratory values performed within 21 days, inclusive, prior to administration of temozolomide.

4. Patients must have an adequate number of autologous stem cells available defined as a minimum of 2 x 106 CD 34+ cells/kg and preferably at least 5 x 106 CD 34+ cells/kg.

Exclusion Criteria:

1. Previous myeloablative therapy

2. Frequent vomiting or medical condition that could interfere with oral medication intake (e.g., partial bowel obstruction)

3. Previous or concurrent malignancies at other sites with the exception of surgically cured carcinoma in-situ of the cervix and basal or squamous cell carcinoma of the skin. Patients with prior malignancies which have not required anti-tumor treatment within the preceding 24 months are eligible.
