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meant that several existing drugs have been found to be effective in treating conditions other than the ones they were originally made and patented for.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...
