Glioma

Clinical Trials

Below is a list of Glioma clinical trials from the clinical trials database at Mayo Clinic.

This list includes only trials about which Mayo researchers choose to publish information. Mayo Clinic may be conducting other trials which are not in this database. Mayo's clinical trials include experimental treatments, often unavailable elsewhere, which frequently lead to improved patient care for people worldwide. Patients should ask their doctor at Mayo about clinical trials appropriate for their situation.

A Phase II Study of Conformal Radiotherapy in Patients with Low-Grade Gliomas
Older children with low grade gliomas that have come back after surgery or are causing problems are often treated with radiation therapy. Younger children are usually treated first with chemotherapy but, if the tumor comes back after chemotherapy, they then often also get radiation therapy.

Radiation therapy can cause severe side effects (a problem that happens when the treatment affects the healthy parts of a patient's body). New types of radiation therapy can treat a
smaller area of the body and doctors think that patients who get these kinds of radiation might have fewer side effects. The purpose of this study is to test the safety and effectiveness of this "smaller field radiation" in patients with low grade gliomas. This study will also try to find out if the results of a special test performed on the tumor tissue are related to the way the tumor responds to radiation.

A Phase II Study of Motexafin-Gadolinium and Radiation Therapy for Brainstem Glioma of Childhood
Patients are being asked to take part in this research study because they have been diagnosed with a type of brain tumor called brainstem glioma. Brainstem glioma is a disease in which cancer cells form in the tissues of the brain that is connected to the spinal cord. It is common to enroll children and adolescents with cancer in a clinical trial that seeks to improve cancer treatment over time. Clinical trials include only people who choose to take part. Patients have a choice between a standard treatment for brainstem glioma and this clinical trial.

What is the current standard of treatment for this disease?
The standard treatment for brainstem tumors is radiation therapy. Radiation therapy is the careful use of high-energy radiation to treat cancer. Radiation therapy destroys the cancer cells ability to reproduce. Surgery is not possible because the tumor is located in an area of the brain that is difficult to safely remove. Damage to this part of the brain as a result of the surgery can cause a child to become mentally and/or physically disabled.

Standard Treatment and Procedures Common to all Patients with Brainstem
Glioma

-Central Line
For drugs to be given by vein, the doctor will likely recommend that the patient has a central venous line placed.

-Magnetic Resonance Imaging (MRI)
MRI uses radio waves and a strong magnetic field rather than x-rays to provide clear and
detailed pictures of organs and tissues inside the body. An MRI of the brain is performed to measure the size of the tumor to see how the treatment is working.

Methods for Giving Drugs
IV Motexafin-Gadolinium on this study will be given using a needle or tubing inserted into a vein.

Standard Tests and Procedures
The following tests and procedures are part of regular cancer care and may be done even if they do not join the study.
- Physical exams
- Frequent labs to monitor blood counts and blood chemistries
- Urine tests to measure how the kidneys are functioning
- Pregnancy test for women able to become pregnant
- Scans to monitor the patient's response to treatment

Why is this study being done?
The research staff are asking patients to take part in a research study of an anti-cancer medicine called Motexafin-Gadolinium that will be used together with radiation therapy to treat brainstem gliomas.

The overall goals of this study are to:
- Find out how well Motexafin-Gadolinium treatment plus radiation therapy controls the growth of brainstem gliomas;
- Learn more about the effects, good or bad, of Motexafin-Gadolinium treatment plus radiation therapy on patients with brainstem gliomas

Radiation therapy cures less than one out of ten children. Giving chemotherapy after radiation has not improved the therapy. The researchers want to try an experimental combination of giving Motexafin-Gadolinium each day just before the radiation treatment to try to make the radiation therapy work better than it does when it is given alone.

This is a Phase II study of the experimental drug Motexafin-Gadolinium along with
radiation therapy. A Phase II study is done to find out how well the drug improves the
disease. A Phase I clinical trial has been completed. The highest dose without too many
side effects was found in that study. The research staff want to find out if combining Motexafin-Gadolinium with radiation therapy is a better treatment than radiation alone, and if children treated this way will be more likely to be cured.

A Phase II/III Randomized Study of CDX-110 Vaccine with Radiation and Temozolomide (Temodar) in Patients with Newly Diagnosed Glioblastoma Multiforme
Patients are being asked to take part in this research study because they have been diagnosed with glioblastoma multiforme (GBM) and have had surgery to have it removed. Their doctor has also determined that temozolomide, a commonly used chemotherapy for this disease, is an appropriate therapy for the patient. This study will find out whether adding the CDX-110+GM-CSF vaccine to temozolomide is better or worse than temozolomide by itself at preventing brain tumors from growing, and helping patients with brain tumors live longer.

The CDX-110 + GM-CSF vaccine is an experimental (investigational) vaccine that is being tested to treat glioblastoma by activating the immune system to fight the cancer.
An investigational vaccine is one that is not approved by the U.S. Food and Drug Administration (FDA). The purpose of CDX-110 is to "train" the immune system to recognize a protein called EGFRvIII. About half of the glioblastoma tumors contain EGFRvIII, and EGFRvIII has only been found in cancer cells. It is hoped that when CDX-110 is given to a patient with a glioblastoma tumor containing EGFRvIII, the immune system will "recognize" and kill the glioblastoma cells.

GM-CSF is a man-made version of a substance naturally produced by a patient's body that "activates" the immune system. GM-CSF has been approved by the FDA as a treatment to help bone marrow recovery after bone marrow transplants, and to help restore white blood cells after chemotherapy in certain cancer patients. GM-CSF has also been used in many clinical studies, including studies that investigate GM-CSF in combination with different cancer vaccines as an "immune activator". Thus, it is hoped that using GM-CSF with CDX-110 will increase the immune response against tumor cells.
Patients will receive GM-CSF at a dose of 150 micrograms. This dose is significantly lower than the FDA approved dose for bone marrow stimulation (the study dose is about one-third of the FDA-approved dose).

Temozolomide is a chemotherapy drug (capsule that is taken by mouth) that has been approved by the FDA for the treatment of brain cancer. Temozolomide, along with radiation therapy and surgery, is currently the most common treatment, and is generally considered the best available treatment, for this type of brain tumor.

Phase III Trial Comparing Conventional Temozolomide (Temodar) with Dose-Intensive Temozolomide (Temodar) in Patients with Newly Diagnosed Glioblastoma
A recent study demonstrated that combining a drug called temozolomide with radiation treatment and following this treatment with temozolomide treatment improved tumor control compared with radiation alone.
This study is being done to:
- find out whether increasing the duration of the temozolomide treatment after radiation from 5 days out of 28 days (standard-dose schedule) to 21 days out of 28 days (dose-dense schedule) will further improve the outcome.
- find out what effects (good and bad) this change in drug schedule has on the patient and their tumor compared with standard treatment.
- find out whether the response to temozolomide and the overall outcome depend on whether or not the tumor contains particular genetic materials called the MGMT gene.

Treatment with Sorafenib (Nexavar) and CCI-779 (Temsirolimus) in Patients with Recurrent Glioblastoma
This study is being done:
-To find the highest dose of sorafenib that can be given without causing unacceptable bad side effects.
-To find out what effects (good and bad) sorafenib and CCI-779 have on a patient and the brain tumor.
-To compare patient's response to sorafenib and CCI-779 with laboratory studies of a patient's blood cells and tumor tissues.
-To look at sorafenib and CCI-779's ability to slow down the growth of the tumor.
A tumor has "switches" that turn on tumor cell growth and division. These two drugs are thought to prevent two of the main switch pathways in the tumor cells from working properly, which hopefully might prevent the cells from growing. Sorafenib and CCI-779 are experimental drugs not yet approved by the Food and Drug Administration.
