Ernest Beutler (1928 - 2008)

Beutler was one of the key clinician scientists involved in the development of Cladribine. Read his oral history here, and watch his acceptance speech of the Wallace H. Coulter Award for Lifetime Achievement in Hematology here.





Ernest was also the father of Bruce A Beutler (*1957), who happened to become the 2011 Nobel Prize Laureate, together with Jules A Hoffmann, for "their discoveries concerning the activation of innate immunity".

Re-purpose Cladribine !

Here's the email I sent Chuka Umunna on 18 Oct: 


Dear Mr Umunna

I am contacting you about the drug re-purposing Bill to ask for your support to see it become Law. I believe it comes before the house on November 6. I attach some documents setting out the case for the Bill and please excuse me if you are already familiar with the arguments.

Breakthroughs in research have meant that several existing drugs have been found to be effective in treating conditions other than the ones they were originally made and patented for. They are referred to as “off patent” drugs. Repurposing these could have potentially huge benefits for many people suffering from conditions like multiple sclerosis (MS) and Cancer. They can be supplied at low cost by Generic Drug companies. The annual treatment for a patient may be less than £1,000 versus over 20x the cost for patented alternatives if in fact they exist. The savings would be of great benefit to patients, the NHS and the taxpayer, and could lead to treatment for many people whose treatment is denied by NICE on the grounds of cost.

However, drugs need to be licensed and approved for their new uses in order to be made available and there is little commercial incentive for pharmaceutical companies, who normally sponsor this process, to do so for off patent treatments. This is largely because prices generally fall a great deal once the patent has expired. There is no mechanism in place to enable licensing of drugs for uses other than their original purpose. Even if a doctor can refer to strong evidence in support of prescribing an off-patent drug to a patient, they would likely be put off by the potential personal liability they may face in doing so. 

There are thus political, legal and commercial barriers in place to prescribing off patent drugs. The Bill seeks to overcome these barriers by obliging the Government to act in the public interest through the process of the Medicines and Healthcare Regulatory Agency (MHRA) to license and approve off-patent, repurposed drugs for use on the NHS. 

The Bill is strongly supported by medical charities and specialists in the NHS, including myself - I am a Reader in Clinical Neurology at Queen Mary University of London & Consultant Neurologist at Barts Health NHS Trust.  As a clinical academic with an interest in MS, I know that early effective treatment of people with MS is key for a beneficial long term outcome.  I therefore have a particular interest in the re-purposing of Cladribine, a drug licensed in the UK for patients with hairy cell leukaemia.  There is evidence from phase III trials that Cladribine is highly effective and safe for people with MS.  The annual cost of Cladribine treatment in MS would be under £1,000 compared to licensed drugs of lesser efficacy that cost 20x or more.  I would be very happy to expand on this example further if you are interested and have the time; just call me on my mobile xxx.

For now, I do hope you are able to support the Bill. Please let me know if there is anything further I can do to promote it.

With best wishes

Sincerely Yours,
Klaus Schmierer
I'll keep watching out for comments by my MP, over and above his auto-reply...

Cladribine

Cladribine (trade names Leustatin, Litak and Movectro) is a drug used to treat hairy cell leukemia (HCL, leukemic reticuloendotheliosis) and multiple sclerosis. Its chemical name is 2-chlorodeoxyadenosine (2CDA).


5-(6-Amino-2-chloro-purin-9-yl)-2-(hydroxymethyl)oxolan-3-ol

As a purine analog, it is a synthetic anti-cancer agent that also suppresses the immune system. Chemically, it mimics the nucleosideadenosine and thus inhibits the enzyme adenosine deaminase, which interferes with the cell's ability to process DNA. It is easily destroyed by normal cells except for blood cells, with the result that it produces relatively few side effects and results in very little non-target cell loss.

Cladribine was designed by Dennis A. Carson as an anti-lymphocyte compound, while he was at The Scripps Research Institute in La Jolla, California. It was first synthesized at Brigham Young University.The pharmacology and clinical applications were researched by scientists at Johnson and Johnson, which filed the New Drug Application and launched the drug in 1993.

Cladribine was designed based on information about an immune deficiency disease called adenosine deaminase deficiency. Carson described it as "a targeted agent directed against lymphocytes at a time when there was no such thing as targeted agents".

In 2008, Ernest Beutler of The Scripps Research Institute won the Wallace H. Coulter Award for Lifetime Achievement in Haematology from the Coulter Foundation and theAmerican Society of Hematology in part because of the clinical trials he ran, which established cladribine as the most effective treatment for hairy cell leukemia (HCL).
