NICE Appraisals: Rare Diseases Treatments

Liz Twist Excerpts

Thursday 21st March 2019 Commons Chamber

[Liz Twist (Blaydon) (Lab)]

I beg to move,

That this House believes that NICE appraisal processes do not properly address the medical treatment needs of people with rare diseases such as muscular dystrophy, phenylketonuria and cystic fibrosis; and calls on NICE to urgently review the appraisal process.

I thank my hon. Friend the Member for North Tyneside (Mary Glindon), who is chair of the all-party group on muscular dystrophy, and the hon. Member for Strangford (Jim Shannon), who is chair of the all-party group on cystic fibrosis, for their help in securing this debate.

My constituent Archie McGovern is 12 years old. He is bright and lively, and full of beans now, but it has not always been like that way because Archie has PKU— phenylketonuria. Putting it simply, PKU is a genetic condition that means Archie and others are unable to handle phenylalanine, which is found in protein—so no meat, no fish and no dairy products. There is a whole range of other things that we would not think had protein in them: the list is endless. On top of that, he has to take a protein substitute drink—if we can call it that, as it is very unpleasant—to keep the balance right.

At present PKU is not curable, and a hugely restrictive diet is the only way of controlling the condition throughout childhood and adult life. The condition is picked up by the pinprick test at birth, and for those identified as having PKU that is the start of a difficult lifetime of dietary control. For children that is especially difficult, but it is also very important because failure to control the condition can lead to serious neurological problems.

That is how it was for Archie until quite recently, but there is a treatment that can help to control PKU. It is called Kuvan, and although it was licensed 10 years ago and is widely available in many countries in Europe, and further afield, it is not available to patients in the UK. Not everyone with PKU responds to Kuvan, but it is believed that more than 20% of people will respond well and see a significant improvement in their life.

[James Morris (Halesowen and Rowley Regis) (Con)]

The hon. Lady makes an important point about Kuvan and PKU. As she will know, last year I and other Members—including the hon. Member for Dudley North (Ian Austin)—took part in the MPs’ PKU diet challenge, so I am well aware of the restricted diet that is required for those who suffer from that condition. The way that NICE evaluates Kuvan does not take into account the social costs associated with the alternative treatment for PKU. That highly restrictive diet impacts on families and wider society, and NICE should consider that point.

[Liz Twist]

Like the hon. Gentleman, I took part in the PKU diet for a day challenge. It was indeed very restrictive, even though I knew it was only for one day.

Archie is one of those who responds well to Kuvan, and last year, his parents took the difficult decision to pay to buy him the drug. That took a great deal of soul searching on their behalf, and it cost them dear—£25,000 a year, even though Archie is currently on just half a dose. They know that for many people with PKU, or for parents with more than one child who has PKU, it is simply not possible to self-fund, and they are acutely conscious of the unfairness of that. The difference that Kuvan has made to Archie is real and significant: increased concentration and energy, so that he can make the best of his education; no recurring mouth ulcers, which were a real problem; and a chance substantially to increase the number of exchanges he can have, and eat a more normal diet. For Archie, Kuvan has made a real difference.

Archie’s case, and those of many others in other constituencies, prompted us to form the all-party group on phenylketonuria, and to consider how Kuvan could be made available to those who would benefit from it. Nearly 10 years after Kuvan was approved, that treatment does not seem to have been an appraised, and in England it is still not available on the NHS. Since we set up the group, there has been a move for Kuvan to be appraised by NICE, and discussions have been held with NHS England about a managed access agreement. We were disappointed to learn just before Christmas that no agreement had been reached on that managed access agreement, and that the NICE appraisal was to be via the single technology appraisal route, and not the highly specialised technologies programme. I understand that following a legal challenge, the Department of Health and Social Care is again considering the appropriate appraisal route, and the all-party group has made representations on that point.

When talking about the NICE appraisal system it is easy to get lost in technical details—QALYs, and everything else, that means nothing to people on the street—but what really concerns people is whether or not there is a fair chance that the drugs they need will be fairly assessed and made available on the NHS.

[Thelma Walker (Colne Valley) (Lab)]

I thank my hon. Friend for securing this debate. One of my constituents suffers from Batten disease and is receiving cerliponase alfa on compassionate grounds. However, NICE will not now recommend that treatment, which in part is due to cost. Does my hon. Friend share my view that allowing patients on to clinical trials when there is no funding to deliver the treatment, places them and their families in an incredibly difficult and uncertain position regarding their future?

[Liz Twist]

I certainly agree, and such things happen too often. We need a system that properly evaluates those drugs.

[Mark Tami (Alyn and Deeside) (Lab)]

I have certainly found that NICE sometimes says that the pool of people is not big enough to evaluate, but the clue is in the title: these are rare diseases. NICE cannot carry on doing that, particularly in cases where it is clear that the drug has a really positive effect.

[Liz Twist]

I agree with my right hon. Friend. Indeed, that is the burden of my speech.

As I was saying, I am not going to get into the fine detail of the process. It seemed to us in the all-party group that many conditions, as my hon. Friends have said, face the same problems. The all-party groups for muscular dystrophy and for cystic fibrosis are two that come to mind, but there are many other rare diseases, as we have heard, that do not have all-party groups but face exactly the same difficulties. Since this debate was announced, some other organisations have contacted me to ask me to make sure that we do not forget their concerns.

We found that there are a number of aspects of the NICE appraisal system that are problematic in assessing Kuvan and many other rare drugs. The existence of just two appraisal routes for treatments to be assessed by NICE results in the likelihood of two or more treatments being stuck in the middle by not meeting the restrictive criteria of the highly specialised technology route and therefore being assessed under a single technology appraisal route. Some of them are rare but not rare enough. As we have heard, the majority of treatments for rare diseases are likely to be assessed within the single technology appraisal, which is designed for non-rare treatments. This impacts on both the cost threshold and the approach to evidence, which are all designed for more common diseases.

On lifelong chronic conditions, NICE’s approach values the lifelong cost of treatments. It looks for near future benefits as well. That means it is difficult for chronic diseases such as PKU and treatments that produce lifetime and life-enhancing effects to get access to new treatments. NICE cost appraisals assume that patents do not expire. NICE will assume the existing price of the drug will stay the same. That is illogical as, particularly with older drugs such as Kuvan, the drug will soon go off-patent. This affects the benefits assessment. On non-health costs, NICE performs its calculations based on costs paid and saved by the NHS. That ignores the wider cost to society and individuals caused by diseases like PKU.

I do not seek to criticise NICE staff. They work within a system that we have given them, but it is clear from the many questions to Ministers, debates in this Chamber and in Westminster Hall, the creation of all-party groups, and correspondence with Ministers about individual cases that there is a very real issue here which must be addressed. That is why we are asking, in this motion, for NICE to review its processes to reflect the current issues we face.

Many drug companies have been in touch since this debate was granted to send me briefings. They have been keen to explain their side of the argument and to point out what they see as the problems in the NICE appraisal process for their drugs. There is some overlap with patient concerns, but I am here today to speak on behalf of the community of people with rare diseases, not on behalf of the drug companies. Let me be clear, the fact that this debate is about NICE appraisal processes does not excuse the pharmaceutical companies from their responsibilities. There is a balance to be struck between their need to recover the cost of the development of drugs and make a reasonable profit, and a huge responsibility on them to make their drugs affordable for our NHS.

In this debate, I have focused on PKU and Kuvan. With another drug treatment for PKU on the horizon, Pegvaliase, there is a real worry that even with a drug that may produce really life-changing results for a wider group of patients, those with PKU will again be left without the treatment they need, even when it exists. There are treatments for other rare diseases, too: Spinraza for spinal muscular atrophy and Orkambi for cystic fibrosis, which are not only life-improving but life-extending.

This is quite simple. There are drugs available that can drastically improve the lives of those affected by rare diseases. When I hear that NICE’s appraisal process is an obstacle to improving lives, I feel really angry. We are reducing the lives of children and adults to a cost-effectiveness analysis. We need to find a way forward to amend the appraisal system so that we do not let people fall through the cracks or fall behind. The drug companies must also do their bit to ensure that their drugs are affordable for the NHS, especially when early access via a managed access agreement is being discussed.

That is why today we are calling on NICE to review its appraisal processes and make the necessary changes to stop people falling through the cracks and make available these drugs, which can make such a difference to patients—to people such as my constituent Archie McGovern, whose mum Barbara set me on this path as a new MP.

[Several hon. Members rose—]

--- Later in debate ---

[Liz Twist]

I hope that hon. Members will forgive me if I do not list them all, but I want to respond to the Minister. First of all, Minister, it is not easy for us on the Back Benches to criticise and lobby. It is really difficult for us, because these are our constituents. They are real people who have real conditions. We have tried to be constructive in the debate and said that we have identified issues around the NICE appraisal system that we think need to be addressed urgently. I notice that he mentioned the review and said that our concerns would be drawn to its attention, but will he ensure that there is dialogue and input before the review takes place to ensure that it is not just technical, but addresses the concerns that we have raised?

[Steve Brine]

indicated assent.

[Liz Twist]

I see the Minister nodding, so perhaps that can be recorded in Hansard. He also said that he has heard from us about these issues before, but I can tell him that he will hear from us again—
