NYU 05-40 PBMTC ONC-032P:High Dose Temozolomide,Thiotepa and Carboplatin With Autologous Stem Cell Rescue (ASCR) Followed by Continuation Therapy With 13-cis-retinoic Acid in Patients With Recurrent/Refractory Malignant Brain Tumors
Researchers have used high doses of combination chemotherapy followed by a stem cell rescue
to treat recurrent brain tumors with moderate success. High dose chemotherapy with stem cell
rescue has resulted in long term survival of about 25% in patients with several different
types of recurrent brain tumors. Stem cells are cells in the bone marrow that produce blood
cells. The stem cells are collected from the blood of the patient before the high dose
chemotherapy. Patients are given high doses of chemotherapy to kill every brain tumor cell,
but in the process the cells of the bone marrow are also killed. The previously collected
stem cells are then infused into the patient to rescue the bone marrow and allow for healthy
blood cells to re-populate and grow in the bone marrow. Initial studies used the drug
etoposide along with carboplatin and thiotepa for the high dose chemotherapy. Patients had
severe side effects, especially severe mouth-sores, thought mainly due to the etoposide, and
some patients died from these side effects.
Recent studies have shown that a new drug, temozolomide, is active against some types of
brain tumors. When it was given as a single drug to children with solid tumors, the side
effects were considered to be tolerable. Temozolomide is given by mouth. In this study,
researchers want to give high dose chemotherapy that includes the drugs temozolomide in
place of etoposide, along with thiotepa and carboplatin. Patients will then be given their
own stem cells back to rescue the bone marrow from the chemotherapy. A preliminary trial
using this new drug combination was performed and has shown that patients tolerate this drug
combination, even at the very high doses that will be used in this protocol.
Another drug that is being used in pediatric cancer treatment is called 13-cis-retinoic
acid. This drug is closely related to vitamin A. It is taken by mouth. Cancer cells are
immature cells that have not "grown up" into adult cells that do work in the body.
13-cis-retinoic acid is thought to act on some types of cancer cells to make them mature
into cells that function in the body. It has also been shown in the laboratory to cause some
brain tumor cells to undergo apoptosis. It has been used in other types of pediatric cancers
and research is just beginning to use it for treatment of recurrent brain tumors. In this
study researchers want to give you 13-cis-retinoic acid for 6 months after you recover from
the high dose chemotherapy with stem cell rescue.
