Cancer treatment for MS patients using own stem cells

 In Stem Cell News

By Fergus Walsh, Medical Correspondent, BBC News


UK doctors in Sheffield say patients with multiple sclerosis (MS) are showing “remarkable” improvements after receiving a treatment usually used for cancer.

About 20 patients have used their own stem cells from bone marrow transplants . Some patients who were paralysed have been able to walk again.

Prof Basil Sharrack, from Royal Hallamshire Hospital said: “To have a treatment which can potentially reverse disability is really a major achievement.”

MS, an incurable neurological condition affects around 100,000 people in the UK. Mostly patients in their 20s and 30s.

The disease causes the immune system to attack the lining of nerves in the brain and spinal cord.

Immune system ‘rebooted’
The stem cell transplant – known as autologous haematopoietic (HSCT) – aims to use chemotherapy to destroy the faulty immune system .

The immune system is rebuilt with stem cells from the patient’s own blood. These cells are at such an early stage they’ve not developed the flaws that trigger MS.

Prof John Snowden, consultant haematologist at Royal Hallamshire Hospital, said: “The immune system is being reset or rebooted back to a time point before it caused MS.”

About 20 MS patients have been treated in Sheffield in the past three years. Prof Snowden added: “It’s clear we have made a big impact on patients’ lives, which is gratifying.”

Multiple sclerosis

In MS the protective layer surrounding nerve fibres in the brain and spinal cord (known as myelin) becomes damaged. The immune system mistakenly attacks the myelin, causing scarring or sclerosis.

The damaged myelin disrupts the nerve signals – rather like the short circuit caused by a frayed electrical cable. If the process of inflammation and scarring is not treated then eventually the condition can cause permanent neurodegeneration.

The BBC’s Panorama programme was given exclusive access to several patients who have undergone the stem cell transplant.

Steven Storey was diagnosed with MS in 2013 and, within a year, went from being an able-bodied athlete to needing a wheelchair and losing sensation in much of his body.

He said: “I went from running marathons to needing 24-hour acute care. At one point I couldn’t even hold a spoon and feed myself.”

Within a few days of the transplant he was able to move his toes, and after four months he could stand unaided.

Steven says: “It’s been incredible. I was in a dire place, but now I can swim and cycle and I am determined to walk.

Holly Drewry was diagnosed at 21 and her condition deteriorated after she gave birth to her daughter Isla.

She said “Within a couple of months I got worse and worse. I couldn’t dress or wash myself; I didn’t even have the strength to carry my daughter.”

Holly needed a wheelchair before her transplant, but after the treatment she walked out of hospital.

She said: “It’s been a miracle. I got my life and my independence back and the future is bright again in terms of being a mum and doing everything with Isla.”

Two years on she has suffered no relapses and there is no evidence of active disease on her scans.

Doctors describe her MS as dormant, but there is hope that the transplant might be a permanent fix.


The Royal Hallamshire Hospital – together with hospitals in the United States, Sweden and Brazil – is part of an international trial, MIST, which is assessing the long-term benefits of the stem cell transplant.

All those on the trial have experienced attacks -or relapses – followed by periods of remission.

Paul Kirkham, another MS patient, said he was glad to have had the transplant but added: “It does knock you. I’d rather have done 10 rounds with Mike Tyson.”

The transplant requires a single cost of around £30,000, comparable to the cost of annual MS treatment.

Because the procedure does not involve new drugs but rather an existing therapy using the patient’s own cells, drug companies do not see a profit incentive to get involved.

Prof Richard Burt, Northwestern University, Chicago carried out the first HSCT for MS as long ago as 1995 and is coordinating the international trial which began in 2006.

He said: “There has been resistance to this in the pharma and academic world. This is not a technology you can patent and we have achieved this without industry backing.”

A study published last year involving MS patients in Chicago showed significant reductions in neurological disability, and for some the improvements persisted for at least four years, although there was no comparative control group.

The outcome (in a couple of years) of the more detailed MIST trial could determine whether stem cell transplants becomes a standard NHS treatment for many MS patients.

Dr Emma Gray, head of clinical trials at UK’s MS Society , said: “Ongoing research suggests stem cell treatments such as HSCT could offer hope, and it’s clear that in the cases highlighted by Panorama they’ve had a life-changing impact”.

“However, trials have found that while HSCT may be able to stabilise or improve disability in some people with MS it may not be effective for all types of the condition.”

Dr Gray said people should be aware it was an “aggressive treatment that comes with significant risks”, but called for more research into HSCT so there could be greater understanding of its safety and long term effectiveness.

Panorama is broadcast on BBC One at 20:30 on Monday 18 January 2016.
