Taking a new approach to fighting a deadly brain cancer

CIRM’s 2017 Annual Report will be going live online very soon. In anticipation of that we are highlighting some of the key elements from the report here on the Stem Cellar.

One of the most exciting new approaches in targeting deadly cancers is chimeric antigen receptor (CAR) T-cell therapy, using the patient’s own immune system cells that have been re-engineered to help them fight back against the tumor.

Today we are profiling City of Hope’s Christine Brown, Ph.D., who is using CAR-T cells in a CIRM-funded Phase 1 clinical trial for an aggressive brain cancer called malignant glioma.

“Brain tumors are the hardest to treat solid tumors. This is a project that CIRM has supported from an early, pre-clinical stage. What was exciting was we finished our first milestone in record time and were able to translate that research out of the lab and into the clinic. That really allowed us to accelerate treatment to glioblastoma patients.

I think there are glimmers of hope that immune based therapies and CAR-T based therapies will revolutionize therapy for patients with brain tumors. We’ve seen evidence that these cells can travel to the central nervous system and eliminate tumors in the brain.

We now have evidence that this approach produces a powerful, therapeutic response in one group of patients. We are looking at why other patients don’t respond as well and the CIRM funding enables us to ask the questions that will, we hope, provide the answers.

Because our clinical trial is a being carried out at the CIRM-supported City of Hope Alpha Stem Cell Clinic this is a great example of how CIRM supports all the different ways of advancing therapy from early stage research through translation and into clinical trials in the CIRM Alpha Clinic network.

There are lots of ways the tumor tries to evade the immune system and we are looking at different approaches to combine this therapy with different approaches to see which combination will be best.

It’s a challenging problem and it’s not going to be solved with one approach. If it were easy we’d have solved it by now. That’s why I love science, it’s one big puzzle about how do we understand this and how do we make this work.

I don’t think we would be where we are at without CIRM’s support, it really gave the funding to bring this to the next level.”

Dr. Brown’s work is also creating interest among investors. She recently partnered with Mustang Bio in a $94.5 million agreement to help advance this therapy.
