Name of the Trial

Phase II Randomized Study of Adjuvant Boswellia serrata and Standard Treatment Versus Standard Treatment Alone in Patients With Newly Diagnosed or Recurrent High-Grade Gliomas (CASE-CCF-7348). See the protocol summary 3.

Why This Trial Is Important

High-grade gliomas are among the most common and aggressive forms of adult brain cancer. Swelling of the brain (brain edema) is an often debilitating symptom of glioma and may continue to affect patients even if the tumor is surgically removed.

Resin from the Boswellia serrata tree (frankincense) has been shown in animal and human studies to reduce inflammation, which is a primary cause of brain edema. Additionally, laboratory studies suggest that B. serrata resin may also cause human brain cancer cells to undergo programmed cell death (apoptosis).

In this trial, patients will be randomly assigned to take an herbal preparation of B. serrata orally four times a day in conjunction with standard treatment for six months or to take standard treatment alone for six months. All patients are advised to eat low-fat healthy diet. Diets rich in red meat contain a substance called arachidonic acid, and chemicals in fat can be converted to arachidonic acid. Arachidonic acid is converted in the brain to signaling molecules called eicosanoids that may promote inflammation and tumor growth. Doctors want to see if B. serrata can help reduce brain edema, tumor growth, and levels of 5-lipoxygenase, an enzyme that helps convert arachidonic acid to eicosanoids, in these patients when combined with standard treatment.

"Some small studies have suggested that frankincense extract may help limit brain edema and even have an anti-tumor effect," said Dr. Stevens. "We hope that use of this herbal preparation in conjunction with a healthy diet will help improve patient outcomes and act in a complementary fashion with standard treatments for high-grade gliomas."

Who Can Join This Trial

Researchers will enroll 70 patients aged 18 and over with newly diagnosed or recurrent high-grade glioma who have undergone surgery to remove their cancer. See the list of eligibility criteria 4.

Glossary Terms

Boswellia serrata (bos-WEH-lee-uh seh-RAY-tuh)
A tree that belongs to the incense tree family. The tree’s amber-colored resin is used in incense. The resin has anti-inflammatory effects and has been used to treat arthritis, asthma, and ulcerative colitis. It is also being studied in the treatment of brain tumors. Also called frankincense tree.
edema (eh-DEE-muh)
Swelling caused by excess fluid in body tissues.
glioma (glee-OH-muh)
A cancer of the brain that begins in glial cells (cells that surround and support nerve cells).
laboratory study (LA-bruh-tor-ee STUH-dee)
Research done in a laboratory. These studies may use test tubes or animals to find out if a drug, procedure, or treatment is likely to be useful. Laboratory studies take place before any testing is done in humans.
recurrent cancer (ree-KER-ent KAN-ser)
Cancer that has recurred (come back), usually after a period of time during which the cancer could not be detected. The cancer may come back to the same place as the original (primary) tumor or to another place in the body. Also called recurrence.
