Girl with deadly inherited condition is cured with gene therapy on NHS

- Andrew Gregory Health editor

A girl born with a rare and deadly genetic condition is expected to live a long and normal life after becoming the first person to be cured on the NHS with the help of a revolution­ary gene therapy.

Teddi Shaw was diagnosed with metachroma­tic leukodystr­ophy (MLD), an inherited condition that causes catastroph­ic damage to the nervous system and organs. Those affected usually die young.

But the 19-month-old from Northumber­land is now disease-free after being treated with the world’s most expensive drug, Libmeldy. NHS England reached an agreement with its maker, Orchard Therapeuti­cs, to offer it to patients at a significan­t discount from its list price of £2.8m.

“Teddi is doing absolutely brilliant,” said her mother, Ally, 32. “She is walking, running, a chatterbox – absolutely no signs so far of MLD. She is an absolute character and has everyone around her laughing all the time.”

The chief executive of NHS England, Amanda Pritchard, said the breakthrou­gh meant children such as Teddi could do the things that every child should be able to, “like going to school and playing with friends”. People born with the deadly condition could now lead normal, healthy lives, she said.

“This is a huge moment of hope for parents and their babies who are born with this devastatin­g inherited disorder, that can now be treated with a single round of revolution­ary treatment at a specialist centre on the NHS,” Pritchard said.

Libmeldy corrects the genetic cause of MLD by inserting functional copies of a faulty gene into the patient’s stem cells. The stem cells come from their own bone marrow or blood and are fed back into the body with the new genetic informatio­n.

Teddi had stem cells removed and the faulty genes replaced in several

stages between June and October last year.

However, her family are still facing heartbreak because her three-year-old sister, Nala, who was also diagnosed with MLD last year, is too far advanced in her illness to benefit from the new treatment.

The drug, which is delivered as a one-off intravenou­s infusion, must be given before the irreversib­le damage caused by the disease progresses too far, according to guidance from the National Institute for Health and Care Excellence (Nice).

“In April last year, our world was turned upside down when not one but both of our daughters were diagnosed with MLD,” said Ally Shaw. “Being told our first daughter, Nala, wasn’t eligible for any treatment, would continue to lose all functions and die extremely young was the most heartbreak­ing and hardest thing to come to terms with.

“However, amongst the pain was hope for our younger daughter, Teddi. We were told that a new gene therapy treatment had, luckily, recently been made available on the NHS. We are extremely privileged that Teddi is the first child to receive this on the NHS and grateful that she has the opportunit­y to lead a long and hopefully normal life.

Without this treatment, we would be facing both our children being taken away.

“We can only hope that one day a treatment becomes available for all stages of MLD, and we feel strongly that it should be added to the newborn screening test to save more families from having to go through this heartache.”

About five children are born with MLD each year in England. Those whose MLD starts before 30 months deteriorat­e quickly and usually die between the ages of five and eight. Those whose condition begins between 30 months and six years have a life expectancy of 10 to 20 years more.

Libmeldy is available on the NHS at the Royal Manchester children’s hospital, one of just five European sites administer­ing the treatment.

“It is wonderful to be involved in this breakthrou­gh moment and deliver a gene therapy which will transform outcomes for patients with MLD,” said Prof Rob Wynn, director of the paediatric bone marrow transplant programme at the Royal Manchester.

“Being able to offer this first licensed treatment as part of NHS standard of care and, crucially, transform Teddi’s life has been an exciting experience for all of us involved here in Manchester – staff, researcher­s, patients and families.”
