inventor Mike Jensen as chief scientist: In 2021, the FDA approved Bristol Myers Squibb’s Breyanzi for some adult lymphoma patients, making it the third CAR-T therapy to become commercially available.
The treatment was invented at Seattle Children’s Hospital, and the first clinical study was in pediatric patients. Mike Jensen, chief therapeutics officer at Seattle Children’s and the physician-scientist behind Breyanzi, hoped that Bristol Myers would seek approval for children next.
That never happened.
To ensure his next therapies — a suite of CAR-Ts targeted at brain cancers — do become available to children, Jensen is leaving Seattle Children’s and launching Brainchild Bio, where he is the chief scientific officer. Seattle Children’s is the sole funder of the new company, though it declined to disclose how much it is investing in the biotech.
The funding from the hospital should last two years, according to CEO Steven Brugger, who led pneumococcal vaccine developer Affinivax until it was bought by GSK in 2022. A biotech that is solely funded by a children’s hospital is uncommon, and Brugger makes a compelling addition. He started Affinivax with backing from the Gates Foundation, also atypical in an industry where early companies are largely funded by venture capital.
Jensen told Endpoints News that the company’s goal is to fill the gap between academic and commercial development — and to make sure therapies that started at Seattle Children’s become commercially available for kids. “We’re coming at it with a kids-first approach to give them a chance to have access to these really transformational medicines,” he said.
Once experimental treatments are handed off to a third party, “you really lose that connectivity,” Jensen said. “And you have an uphill argument because, eventually, push comes to shove [and] they need to go for large indications.”
He co-founded Juno Therapeutics, which was home to Breyanzi before the biotech was acquired by Celgene. In 2019, Bristol Myers swooped in and bought Celgene for $74 billion. Jensen also co-founded Umoja Biopharma, a company developing in vivo cell therapies, and co-chairs its scientific advisory board.
“Trickle-down therapeutics from adults to kids has not been a very efficient way to get children the medicines they really need,” Jensen said.
A ‘quad’ CAR-T
A core team of around 20 people from Seattle Children’s will be migrating to Brainchild Bio to kickstart the company. They will be focused on their “brainchildren,” the name Jensen coined for his pediatric brain cancer therapies.
First, they plan to push a CAR-T therapy for diffuse intrinsic pontine glioma, or DIPG, through an early-stage clinical study. DIPG is an aggressive tumor that… #lucidquest #genetherapy #celltherapy
