Patiromer for treating hyperkalaemia Single Technology Appraisal Response to consultee, commentator and public comments on the Appraisal Consultation Document (ACD) Type of stakeholder: Consultees – Organisations that accept an invitation to participate in the appraisal including the companies, national professional organisations, national patient organisations, the Department of Health and Social Care and the Welsh Government and relevant NHS organisations in England. Consultees can make a submission and participate in the consultation on the appraisal consultation document (ACD; if produced). All non-company consultees can nominate clinical experts and/or patient experts to verbally present their personal views to the Appraisal Committee. Company consultees can also nominate clinical experts. Representatives from NHS England and clinical commissioning groups invited to participate in the appraisal may also attend the Appraisal Committee as NHS commissioning experts. All consultees have the opportunity to consider an appeal against the final recommendations, or report any factual errors, within the final appraisal document (FAD). Clinical and patient experts and NHS commissioning experts – The Chair of the Appraisal Committee and the NICE project team select clinical experts and patient experts from nominations by consultees and commentators. They attend the Appraisal Committee meeting as individuals to answer questions to help clarify issues about the submitted evidence and to provide their views and experiences of the technology and/or condition. Before they attend the meeting, all experts must either submit a written statement (using a template) or indicate they agree with the submission made by their nominating organisation. Commentators – Commentators can participate in the consultation on the ACD (if produced), but NICE does not ask them to make any submission for the appraisal. Non-company commentator organisations can nominate clinical experts and patient experts to verbally present their personal views to the Appraisal Committee. Commentator organisations representing relevant comparator technology companies can also nominate clinical experts. These organisations receive the FAD and have opportunity to report any factual errors. These organisations include comparator technology companies, Healthcare Improvement Scotland any relevant National Collaborating Centre (a group commissioned by NICE to develop clinical guidelines), other related research groups where appropriate (for example, the Medical Research Council and National Cancer Research Institute); other groups such as the NHS Confederation, the NHS Commercial Medicines Unit, the Scottish Medicines Consortium, the Medicines and Healthcare Products Regulatory Agency, the Department of Health and Social Care, Social Services and Public Safety for Northern Ireland). Public – Members of the public have the opportunity to comment on the ACD when it is posted on the Institute’s web site 5 days after it is sent to consultees and commentators. These comments are usually presented to the appraisal committee in full, but NICE reserves the right to summarise and edit comments received during consultations, or not to publish them at all, where in the reasonable opinion of NICE, the comments are voluminous, publication would be unlawful or publication would be otherwise inappropriate. Please note: Comments received in the course of consultations carried out by NICE are published in the interests of openness and transparency, and to promote understanding of how recommendations are developed. The comments are published as a record of the submissions that NICE has received, and are not endorsed by NICE, its officers or advisory committees.

Society for derive major prognostic benefit from with angiotensin converting enzyme inhibitors (ACEI), angiotensin Heart Failure receptor blockers (ARBs), sacubitril/valsartan, beta blockers and mineralocorticoid receptor antagonists (MRAs) [data summarised in ESC guidelines, 1]. For many of these drugs, the benefit is additive. For example, the combination of sacubitril/valsartan, beta blocker and MRA results in a reduction of all-cause mortality with a hazard ratio of 0.37 against placebo [2]. Renin angiotensin aldosterone inhibitors (RAASi) may lead onto hyperkalaemia, in particular in patients with co-existent chronic kidney disease (CKD). In some instances this may result in clinicians stopping or reducing doses of one or more RAASi. The British Society for Heart Failure (BSH) feel that the management of hyperkalaemia during co-existent RAASi use should be directed according to the strength of indication for the RAASi. That is when the drugs have clear prognostic benefit (i.e. HFREF or post MI left ventricular systolic dysfunction or CKD with albuminuria) every effort should be made to ensure their continuation at highest possible dose. This is very different to when they are used to treat hypertension – here many other good alternatives exist and switching the drug to a different class seems very appropriate, if problems such as moderate or severe hyperkalaemia ensue. Similarly if a patient has heart failure with preserved ejection fraction (HFPEF) RAASi have not been shown to be of prognostic benefit. The BSH, Renal Association (RA) and Think Kidneys have published guidelines on the management of changes in renal function and potassium on initiation and up titration of RAASi in patients with heart failure [3]. 1. 2016 ESC Guidelines for the diagnosis and treatment of acute and chronic heart failure: The Task Force for the diagnosis and treatment of acute and chronic heart failure of the European Society of Cardiology (ESC).

As such the BSH agree that there should not be a very broad indications such as 'hyperkalaemia in adults' for these drugs.

It is uncertain as to how many patients this might effect, but we feel the numbers will be very small. Some patients who develop hyperkalaemia will have other issues such as worsening renal function and/or hypotension, which themselves might limit continued prescribing of RAASi. In summary,
