Bubble baby treatment cleared to restart clinical trial

Three families battling a life-threatening immune disorder got some great news last week. A clinical trial that could save the life of their child has once again been given the go-ahead by the US Food and Drug Administration (FDA).

The clinical trial is the work of UCLA’s Dr. Don Kohn, and was strongly supported by CIRM. It is targeting ADA-SCID, a condition where the child is born without a functioning immune system so even a simple infection could prove fatal. In the past they were called “bubble babies” because some had been placed inside sterile plastic bubbles to protect them from germs.

Dr. Kohn’s approach – using the patient’s own blood stem cells, modified in the lab to correct the genetic mutation that causes the problem – had shown itself to be amazingly effective.  In a study in the prestigious New England Journal of Medicine, the researchers showed that of 50 patients treated all had done well and 97 percent were considered cured.

UCLA licensed the therapy to Orchard Therapeutics, who planned to complete the testing needed to apply for permission to make it more widely available. But Orchard ran into problems and shelved the therapy.

After lengthy negotiations Orchard returned the therapy to UCLA last year and now the FDA has given clearance for UCLA to resume treating patients. That is expected to start early next year using CIRM funds left over when Orchard halted its work.

One of the people who played a big role in helping persuade Orchard to return the therapy to UCLA is Alysia Vaccaro. She is the mother of Evie, a child born with ADA-SCID who was cured by Dr. Kohn and his team and is now a thriving 9 year old.

You can watch an interview we did with Alysia about the impact this research has had on her family, and how important it is for other families with ADA-SCID kids.

  1. Yeah, CIRM! But please look into a way to release new advancements, that are funded by CIRM and the California tax payers, as “Open Source” medicines at low cost for everyone!
