项目摘要
When ultrasound bursts are combined with a circulating microbubble agent, a temporary disruption in the
blood-brain barrier (BBB) is induced that lasts for several hours. This procedure, when combined with ultra-
sound devices that can accurately and safely focus an ultrasound beam through the intact skull, has a great
potential as a completely noninvasive and targeted method to deliver drugs to the brain. Numerous animal
studies have shown that this method does not produce any significant damage to the brain and can also in-
crease the permeability of tumor blood vessels. While this technology has potential for a wide range of brain
disorders, we think it is likely that initial tests of the method will be in brain tumors. Brain metastases, for
which there may already exist drugs that are effective outside the brain, may be a good target to test clinical
efficacy. This project aims to perform studies that are needed before we can start a clinical trial to test the
efficacy of BBB and blood-tumor barrier disruption for targeted drug delivery in brain tumors. We are aiming
to be ready to test the efficacy of this technique in breast cancer brain metastases patients, and we have tai-
lored the research around that application. We will perform three studies that evaluate safety and effective-
ness of focused ultrasound induced BBB disruption under scenarios we will encounter in a clinical trial. First,
we will evaluate the relative efficacy of the two currently-approved agents for treating HER2-positive breast
cancer, trastuzumab (Herceptin(R)) and lapatinib (Tykerb(R)). Next, we will evaluate the safety and effectiveness
of inducing BBB disruption in the brain and in brain tumors after radiation therapy, a scenario that we expect
to encounter in patients. Finally, we will test the safety of repeatedly disrupting extensive volumes in the
brain in nonhuman primates using a clinical MRI-guided transcranial focused ultrasound system. These is-
sues all need to be resolved before initiating clinical trials. At the end of the grant, we expect to have the data
necessary to begin clinical trials on the efficacy of this promising image-guided targeted drug delivery
method.
RELEVANCE (See instructions);
Ineffective drug delivery caused by the blood-brain barrier, limited permeability of tumor blood vessels, and
other factors are thought to lead to the poor outcomes of patients with breast cancer metastases in the brain.
Focused ultrasound, when combined with a microbubble agent, offers a noninvasive method to get around
these barriers and deliver effective doses of drugs to the brain and to brain tumors. Here we will perform the
work needed before we can begin clinical trials evaluating the efficacy of this method.
