Burosumab and XLH

Latest News for England

On 29 November 2023, NICE published an update on their evaluation of burosumab for adults in England. NICE acknowledges that XLH has a large positive impact on the quality of life in adults and that current treatments are ineffective, indicating a significant unmet need. Despite these benefits, NICE has expressed concerns about the cost-effectiveness of the treatment within NHS resources.

This is not a final decision, we were given a 4-week consultation period to submit further evidence by 3rd January. This phase is now complete and a NICE executive committee met on February 15th to discuss the consultation responses. As part of this, XLH UK have contributed, sharing the views and experiences of people with XLH and their families. We will be advised when a final decision is ready to be published and will update the community then.

Use of Burosumab for Adults In UK (2023)

As the marketing authorisation for the use of burosumab in England, Wales, Scotland, Ireland and Northern Ireland was originally for use in children with XLH, it excluded using burosumab in adults with XLH. However Health Technology Assessments are in progress across UK and Eire.

XLH UK and clinical experts from across UK actively maintain a good relationship with health technology assessors, including NICE. When opportunities arise, we advocate for better treatments for the adult XLH population. Our patient stories and surveys help health technology assessors better understand the lived experience of XLH and the impact it has on families, carers and friends.

Scotland: In 2023, the Scottish Medicines Consortium (SMC) recommend the use of burosumab in adults. This means that both children and adults can access burosumab from the NHS in Scotland that have a confirmed diagnosis and meet their biochemical and clinical criteria. The recommendation for adults was made through the ultra-orphan pathway, which is used for medicines for very rare diseases. This pathway allows people with XLH to access burosumab while more data is collected to support its effectiveness. The SMC will review this evidence in three years to make a final decision on its routine use.

Health Technology Assessment FAQs

What is the RUDY Study and why is it important?

About RUDY
RUDY is a study in Rare diseases. Headed up by a research team at the University of Oxford, Rudy aims to transform clinical care for participants through patient driven research.

Overview
Living with XLH can at times be complicated, especially as we age. Because of the very nature of living with a rare disease, it makes both collecting data on what works and what doesn’t work limiting because of the small patient population. Another difficulty is the wide range in symptoms that people with XLH can have. RUDY addresses this by releasing frequent surveys over time to better understand how XLH changes as we age.

Why is RUDY important right now?
NICE, who are assessing the cost effectiveness of burosumab in the eligble adult XLH population require more data on specific aspects of daily life. Those include: impact of pain, family and carer burden, effectiveness of phosphate and alfacalcidol, pain killers, mental health, fractures, and fractures specifically before during and after any treatment and finally your location.

Which surveys should I complete within RUDY?
There are many surveys which may take approximately 1-2 hours to complete. Please login and locate the ‘to do’ page where you will have 2 sections. All surveys are preferable, however if time is pressing, here are the ones we need completing urgently:

Activities of daily living
Quality of life
Usage of healthcare
Fatigue
Pain
Mental wellbeing
Diagnosis
Medication
Are you a carer
Height and weight
Fracture Map – Please add the number of fractures, including ones from many years ago. We need the month and year of recent fractures in the last 5 years. We need everyone to tick either never had or my fractures are completed.

Profile Page
Please add your “Post Code” so we can check how geography affects XLH care.
Please complete the ethnicity section.
And add your main consultant.

In the Diagnosis section, you have the option to email rudy@ndorms.ox.ac.uk to send us a photo or scan of your clinic letter, confirming your patient record.

How are new treatments appraised?

There are different appraisal bodies across the UK. The current guidance is for England, but will be highly influential across the UK.

What are the draft recommendations?

NICE’s committee produced draft guideance and showed that burosumab is a clinically effective treatment, with important benefits for adults with XLH but it cannot be considered to offer sufficient value for money at the current price for them to be recommended for routine use on the NHS. You can find out more about the methods and processes used to assess NHS medicines on NICE’s website. 

The committee recognised the range of challenging symptoms caused by XLH, the large symptom burden it has, the significant effect on the quality of life for those with XLH and their families, as well as the evidence base after the several years of data collection through interim early access agreements. You can read the draft guidance in full here.

What is the charity’s role in the NICE appraisal process?

XLH UK conducts research through surveys and interviews which have been invaluable in providing decision makers with information about the lived experiences of individual and families with XLH. Alongside providing data to NICE as part of the NICE appraisal process, the charity is also a stakeholder. As a representative patient group we can submit additional evidence, call for a wide range of outcomes to be considered as part of the assessment and continue to campaign for all people with XLH to have access to innovative treatments when they need it. 

What has happened to date with the NICE appraisal?

In March 2021, NICE had the first scoping meeting, where stakeholders including XLH UK, gathered with NICE to discuss the best route to assess burosumab for treating XLH in adults.

We were able to highlight:

  • Background information on XLH in adults and the different types of medicines people with XLH may need to take. 
  • Which existing medicines to compare the treatment against to understand how effective they are. 
  • Whether all outcome measures have been included that will capture all the benefits of the treatment. 
  • The significant impact of this treatment for most people with XLH who are eligible to take them.

After a series of discussions with NICE, it was decided that the medicine would be appraised by the Single Technology Appraisal program.

Near the end of 2022, many of you shared your experiences of burosumab to inform XLH UK’s evidence submission. Thanks to 129 individuals in the XLH community, we were able to demonstrate the significant impact that living with XLH can have on your daily life. The XLH community also identified a wide range of benefits to burosumab, including: 

  • Convenience of regimen, which also improves effectiveness by reducing non-compliance. 
  • Reduced need for corrective orthopaedic surgery.
  • Reduced need for pain medication.
  • Reduced disability.
  • Reduced family and financial burden.
  • Increased emotional wellbeing and self-esteem due to increased ability, mobility, function and reduced pain. 

It was in March 2023, that XLH UK provided evidence consisting of Patient Organisation Submission paper and our own research. Our evidence, alongside evidence from clinical experts and Kyowa Kirin, formed the final submission. This allowed NICE’s Technical and Evidence Review Group to assess the cost effectiveness of burosumab in the eligible adult population.

On November 08 2023, NICE’s independent committee met and presented on burosumab. Clinical experts, XLH UK and a patient expert participated. Representatives from Kyowa Kirin were also present and responded to questions from the committee. The second half of the meeting was held in private, and the committee agreed their draft recommendations. 

What happens next?

Following the public consultation period a NICE executive committee met on February 15th to discuss the consultation responses. As part of this, XLH UK contributed, sharing the views and experiences of people with XLH and their families. We will be advised when a final decision is ready to be published and will update the community then. 

What happens to adults already receiving burosumab in England?

While the NICE appraisal is ongoing, access to treatment will continue. 

My child is on burosumab – what will happen to their access?

NICE has already appraised and recommended the use of burosumab to all children with XLH who are aged 1-16 years. Therefore, NHS England, NHS Wales, will continue to prescribe burosumab to eligible children regardless of the outcome for adult treatment.

NHS Scotland evaluated burosumab for children separately and under SMC guidance confirmed that burosumab will be available for children.

If the committee’s final recommendation is that the medicine is not cost effective, will adults already on a burosumab lose access?

We do not know. As a registered stakeholder, XLH UK will be informed of the outcome in confidence after the meeting. The outcome will be publicly released once the guidance is published on the NICE website several weeks after the meeting. 

If the NICE appraisal’s final recommendation is that the medicine is too expensive, what will this mean for adults currently waiting for access (for example, children who have stopped treatment because of puberty)?

While the NICE appraisal is ongoing, access to treatment will continue. This is not a typical process for NICE to undertake and we do not know exactly what will happen at each stage. The initial recommendation announced by NICE on 29 November 2023 is not a final decision, it’s a step in the wider appraisal process and we will continue to advocate for access for everyone who could benefit, now and in the future. 

What is the timetable for the NICE process?
  • Closing date for the RUDY Study and Carer Burden survey: 13 December 2023
  • Closing date for input to consultation: Wednesday 03 January 2024 
  • Second evaluation committee meeting: Wednesday 15 February 2024 
  • If a decision is not reached at the second committee meeting, further discussions will take place. 
  • Timescales for NICE appraisals are set regardless of what the medication or technology they are assessing. What a future timescale is depends on the outcome of the next stage and may be impacted by what Kyowa Kirin or NHS England decide to do. 
  • The outcome will be published on the NICE website several weeks after guidance is finalised. We will be notified in advance of likely publication date.
Will the appraisal outcome apply across the UK?

No, it does not apply to the whole of the UK.

In Wales, guidelines produced by NICE apply (subject to approval by the Welsh authorities) and in Northern Ireland the majority of NICE guidelines apply (subject to approval by the relevant Northern Ireland authorities).

In Scotland, the Scottish Medicines Consortium (SMC) recommended the use of burosumab in February 2023 for in the eligible adult population.

What can I do to help?

You can help by completing our 5-Step Action Plan by December 13th.

The plan has been carefully created to gather additional evidence that XLH UK, along with clincial experts, will be submitting back to NICE in time for the 2nd Committee Meeting.

XLH UK and clinical experts will also be responding to the consultation, to highlight the vital importance of burosumab to the current and future health of adults with XLH.

For those who are unable to submit comments using the online form, responses can be submitted by post or email. However, respondents are strongly encouraged to respond using the online form if they are able to.

I am feeling anxious and worried, what can I do?

We know NICE’s update about its appraisal on 29 November is concerning for many of you and we are here to support you. Please contact us on contact@xlhuk.org and we will get back to you as soon as we can. 
 
It’s important to emphasise that this is not a final decision from NICE and doesn’t affect anyone currently taking burosumab. 
 
We are hopeful that there will be a swift resolution to this uncertainty and are urging Kyowa Kirin, NICE and the NHS to work together to find a solution.
