A young boy near struggling to locomotion by a muscle-wasting illness is backmost connected his feet and moving astir playing pinch friends – acknowledgment to conscionable a azygous dose of 1 of nan world’s astir costly drugs.
Six-year-old Charlie Handt suffers from Duchenne muscular dystrophy (DMD), which causes progressive weakness, nonaccomplishment of mobility and early death.
Each twelvemonth successful nan UK conscionable 100 boys are calved pinch it – nan familial information affects only males and location is presently nary cure. Most scope only their 20s aliases 30s, but acknowledgment to a £2.6 million-a-dose medicine called Elevidys, Charlie, and different young sufferers, whitethorn now person a glimmer of hope.
The pioneering cistron therapy helps nutrient a macromolecule successful nan assemblage needed for musculus maturation which is absent successful youngsters pinch nan condition.
Elevidys has already been offered to immoderate American boys pinch DMD, but it’s not disposable connected nan NHS because wellness regulators are waiting connected nan results from a objective proceedings owed adjacent month.
John Paul Hopkins, 32, from North Wales is hoping to get his boy Rory, 6, who was diagnosed pinch Duchenne muscular dystrophy successful 2021, onto cistron therapy for illustration Elevidys

However, The Mail connected Sunday has been told that contempt nan astronomical costs of Elevidys, it is apt that it will beryllium rolled retired aft children fixed nan curen successful nan US saw marked improvements successful their beingness health.
American clinicians study that children who would usually person been wheelchair-bound by nan property of 11 were alternatively ‘running, jumping and playing’ aft taking nan drug. Others suggested nan effect of Elevidys was truthful important it would let a procreation of DMD patients to unrecorded healthily into adulthood, starring normal lives and getting jobs – thing almost unheard of owed to nan severity of disablement nan unwellness usually causes.
Charlie’s mother, Jennifer, 47, from Connecticut, says: ‘Since he sewage nan infusion [of Elevidys], Charlie has knowledgeable immoderate really promising changes. Before that he was struggling to walk, but now he’s throwing a shot pinch his dada successful nan plot and moving astir pinch different kids.
‘It’s getting harder to show that there’s thing which makes him different from different children. It feels for illustration this is nan first clip I tin exhale since nan diagnosis. We’re not conscionable watching him discarded distant immoderate more.’
DMD prevents nan accumulation of a macromolecule called dystrophin, which is important to musculus mass. Without it, nan musculus fibres gradually break down, yet starring to a full nonaccomplishment of mobility.
Dystrophin is besides needed to modulate and fortify muscles successful nan bosom and lungs, meaning astir DMD sufferers yet dice from bosom aliases respiratory failure, though life expectancy has been accrued successful nan past decade acknowledgment to a number of caller narcotics which tin amended their bosom and lung health.
Daily steroid medicine tin besides thief to slow nan nonaccomplishment of musculus mass, but it is not a peculiarly effective treatment.
‘Twenty years ago, patients would apt dice by nan property of 15, but they’re now often surviving to 30,’ says Dr Diana Castro, a advisor neurologist astatine nan Neurology & Neuromuscular Care Center successful Texas.
‘However, until precocious there’s been thing we could do to thief widen nan clip patients person usage of their bodies, arsenic they thin to suffer mobility by nan property of 20.’
Experts judge nan single-dose drug, fixed arsenic an hour-long infusion, could beryllium nan first action that changes this tragic dynamic, allowing boys pinch DMD to unrecorded longer, healthier lives.
Charlie, pictured, is being treated pinch Elevidys, which costs £2m for a azygous dose
The treatment, besides known arsenic delandistrogene moxeparvovec, useful by introducing a harmless modified microorganism into nan assemblage that contains artificial DNA strands – familial instructions that origin nan muscles to commencement producing a type of dystrophin. Just 1 dose is needed and this should, successful theory, extremity young patients deteriorating.
A caller proceedings that followed 120 children fixed Elevidys will uncover what effect it had connected their expertise to do elemental beingness tasks specified arsenic opinionated up, stepping and running. The supplier is already being fixed to immoderate young boys successful nan US aft wellness regulators nan Food and Drug Administration (FDA), decided nan deficiency of effective DMD treatments justified approving Elevidys earlier nan proceedings concluded.
While immoderate criticised nan determination – including various FDA statisticians who called for much grounds from Sarepta, nan supplier institution down Elevidys – nan watchdog concluded it was ‘reasonably likely’ nan supplier benefited young boys. The FDA decided to initially connection nan supplier to children aged betwixt 4 and five, arsenic nan early studies showed nan astir important improvements successful this property group.
Once nan proceedings information is published, and if nan results are encouraging, nan property scope of children who tin entree Elevidys could widen.
But experts declare location whitethorn beryllium a number of caveats, arsenic immoderate participants knowledgeable terrible broadside effects, including liver damage. For this reason, nan supplier has to beryllium taken pinch a beardown people of steroids to minimise specified risks. The therapy is besides ineffective successful a number of children that transportation protect antibodies which tin termination disconnected nan modified virus. Experts are besides unsure really galore other years it will bargain DMD patients.
Regardless, clinicians who person prescribed nan supplier to their patients opportunity that they person seen astonishing results.
Now Charlie tin subordinate successful pinch nan different children
JENNIFER Handt realised wrong a twelvemonth of her boy Charlie’s birth, arsenic he began missing important milestones, that he was not for illustration different children.
The 47-year-old copywriter from Darien, Connecticut, says: ‘He struggled to move himself complete and still wasn’t walking. I thought it was unusual but didn’t deliberation it would beryllium thing excessively serious, truthful we took him to spot a beingness therapist.’
But Charlie did not amended and, astatine three, he was referred to a neurologist who diagnosed him pinch Duchenne muscular dystrophy (DMD) – a familial information that affects only males and which was erstwhile a decease sentence.
Jennifer adds: ‘It was devastating because I knew what this illness did and really it could impact Charlie’s life, but I was besides hopeful. I’d publication astir nan astonishing experiments which were going connected pinch cistron therapies, and decided early connected that we weren’t going to fto this test ruin our lives – we were going to find a cure for Charlie.’
Jennifer and her hubby Rick were capable to get Charlie connected to nan Elevidys trial, and successful 2022, aged four, he was fixed an infusion.
She says nan betterment successful Charlie’s mobility has been striking.
‘He’s begun to show immoderate very promising signs,’ she explains. ‘Charlie is capable to get up disconnected nan level without utilizing his hands aliases different portion of his assemblage for leverage – nan hallmark trial for really precocious DMD is. This isn’t thing he could do before.
‘He tin climb up stairs easier than earlier and takes portion successful PE lessons for short periods.
‘He is capable to enactment for illustration a normal, patient kid – and it is amazing.
‘We cognize this supplier isn’t a cure, but it could bargain Charlie capable clip for a cure to beryllium recovered successful nan future.
‘This supplier should beryllium disposable to each kid who needs it.’
Speaking astatine an FDA gathering successful June, Dr Linda Lowes, a beingness therapist and DMD researcher, shared nan video of an 11-year-old diligent who was capable to jump and tally down a corridor. ‘This boy should beryllium successful a wheelchair,’ she said, ‘and he is hopping disconnected nan level and running. He is still running, jumping and playing, each because he is connected this medication.’
Dr Castro adds: ‘We’ve seen singular changes successful galore of nan patients we’ve treated. They are experiencing improvements we didn’t deliberation were possible. I judge this supplier could let them to unrecorded healthy, progressive lives agelong capable to get a occupation – thing nan immense mostly of DMD patients person not been capable to do.’
One genitor hoping to get their kid connected to cistron therapy is John Paul Hopkins, 32, from North Wales, whose boy Rory, six, was diagnosed pinch DMD successful 2021.
‘Pretty soon aft Rory was calved we noticed he wasn’t keeping up pinch different kids,’ says John Paul. ‘It took him 19 months to walk, and erstwhile he did he kept falling complete and ever wanted to beryllium down.
‘The test was horrendous. Finding retired that your boy has a fatal muscle-wasting illness that will mean he won’t unrecorded past his teenage years is 1 of nan astir soul-destroying experiences location could perchance be.’
Since past he has been trying to get Rory connected to a objective proceedings for a different cistron therapy drug.
‘Earlier this twelvemonth we travelled to Newcastle to get Rory assessed, but he didn’t walk nan assessment,’ he says. ‘They said we could effort again adjacent year, truthful that’s what we’re going to do.
‘You perceive astir these breathtaking cistron therapies and you want to springiness your kid a chance.
‘Rory is still patient and happy. He needs a wheelchair for agelong distances, but different he’s ever connected nan go, racing astir pinch different kids for illustration he’s Usain Bolt.
‘Getting Rory connected to a supplier for illustration Elevidys would alteration nan world for us. I cognize location are risks attached, but cistron therapy is really his only hope.’
Experts constituent to nan NHS rollout of different costly cistron therapy supplier for a akin information – spinal muscular atrophy (SMA) – arsenic an illustration of really successful these treatments tin be.
In 2021, nan NHS struck a woody to acquisition nan one-off cistron therapy Zolgensma, which costs £1.8 cardinal per dose, making it astatine nan clip nan astir costly supplier successful nan world.
SMA causes progressive nonaccomplishment of movement, paralysis and past death. Untreated children calved pinch nan information thin to dice earlier they scope their 2nd birthday. The therapy useful by replacing nan faulty cistron that causes SMA pinch a patient version. More than 100 children person since received nan treatment, and successful August studies revealed nan numbers of babies dying of SMA has been trim by 90 per cent acknowledgment to Zolgensma and different narcotics taken successful tandem.
‘Approving these one-off treatments for uncommon diseases is challenging because of really costly they are,’ says Emily Reuben, main executive of nan kindness Duchenne UK. ‘But we’ve now seen that, erstwhile fixed early, these cistron therapies activity really good for spinal muscular atrophy patients to nan constituent wherever they’re fundamentally curative.’
British experts declare that, should nan information group to beryllium released adjacent period beryllium positive, NHS spending regulators must o.k. Elevidys for DMD patients.
‘This supplier is besides apt to beryllium very expensive, but if nan results are affirmative and independently verified, location is simply a clear request for it connected nan NHS,’ adds Ms Reuben.
‘This is simply a fascinating, uncharted clip for DMD. If these cistron therapy narcotics are proven to work, nan measurement we attack nan illness will beryllium changed for ever.’
How pharmaceutical firms complaint nan earth
The main logic why Elevidys is truthful costly is because of really analyzable it is to produce.
Each dose contains trillions of genetically modified viruses and has to beryllium customised depending connected nan weight of nan child.
‘Manufacturing these viruses is very expensive,’ says Prof Dame Kay Davies, a geneticist astatine nan University of Oxford. ‘You’ve sewage to make a immense batch and past guarantee each 1 is pure, meaning that it contains precisely what you request it to person and won’t beryllium harmful to nan patient.’
Pharmaceutical firms put billions of pounds into investigation and development, and galore imaginable treatments do not make it past rigorous objective trials. Elevidys is designed to beryllium fixed only erstwhile to a very constricted group of patients, truthful nan precocious value reflects what is needed to move a profit.
They would apt reason that Elevidys could prevention nan NHS money successful nan agelong run, too.
Healthcare for children pinch Duchenne muscular dystrophy is highly expensive. According to investigation carried retired by nan drug’s developer, US-based patient Sarepta, nan illness tin costs arsenic overmuch arsenic £8 cardinal per diligent to treat. Not only does this fig see predominant infirmary visits and medicines, but besides ongoing attraction costs specified arsenic wheelchairs and master carers.
‘There’s nary uncertainty that this supplier would beryllium cost-effective if approved,’ adds Prof Davies.
