After Gene Therapy: Hannah’s Journey Continues

Thirteen-year-old Hannah Sames looked beautiful a few weeks ago at the annual Hannah’s Hope Fund gala near her hometown and mine. She’d put on 15 pounds since her gene therapy for giant axonal neuropathy (GAN) 9 months ago. Hannah wheeled around the teen-packed ballroom, her kinky tendrils draping her smile, chatting with guests.

I looked at her in wonder. Were the extra pounds a response to gene therapy, or just a normal adolescent growth spurt? Were her new abilities to pull herself up from a sitting position and to pick up a crouton with her fingers a consequence of subconsciously trying harder? Or were they, too, due to the 120 trillion gene-bearing viruses sent into the fluid bathing her spinal cord?

It’s too soon to tell. (more…)

Hannah Has Her Gene Therapy For GAN

Hannah Sames and the researcher who created her gene therapy, Dr. Steven Gray.
Last week, 8 years and $8 million fund-raised dollars after the Sames family of Rexford, NY, began their battle against giant axonal neuropathy (GAN), their daughter Hannah finally received gene therapy.

JUST IN TIME
About 120 trillion viruses were injected into the fluid surrounding 12-year-old Hannah’s spinal cord, at the NIH Clinical Center. Each virus carries a working copy of the gene that encodes a protein called gigaxonin. When she awoke, the first thing Hannah said was "I'm hungry!" and soon after posted on Facebook, "I have an amazing family!" Indeed she does.

Although Hannah is the fifth child in the clinical trial, she’s the first whose body doesn’t make the protein at all, thanks to two deletion mutations. She required a separate protocol to suppress her immune system so that it would accept the treatment, which uses the harmless adeno-associated virus to deliver the genes. At one point, it seemed that the clinical trial wouldn't include her, despite the funding from Hannah's Hope Fund. (more…)

The Past and the Future of Gene Therapy

Corey Haas and Hannah Sames sign their photographs in "The Forever Fix: Gene Therapy and the Boy Who Saved It."
Yesterday I had two very special guests at my book talk and signing at the Schenectady library: Eleven-year-old Corey Haas, who is “the boy who saved gene therapy” in the metaphorical phrase in the book title, and eight-year-old Hannah Sames, who will have gene therapy.

Corey and Hannah represent gene therapy’s immediate past and future. They put faces on a once-moribund biotechnology reborn after a series of tragic errors and failures. They are also remarkable children: bright, poised, aware, and charming. They are making history. (more…)
