Table 1 shows each class of mutation and its different characteristics. The most effective treatments to date have exploited a particular characteristic of the dysfunctional cellular process. The first three classes are discussed in greater detail because these are the current priorities for drug developments.
Treating a population with precision medicines — what that could look like. Pictorial breakdown of how the UK cystic fibroris population may be treated in the future. Drugs that promote ribosomal read-through of stop codons, permitting complete translation of mRNA, may represent a potential treatment strategy for this type of defect . Aminoglycosides have previously demonstrated to promote read-through of PTCs, therefore, a post-hoc analysis in subjects not concomitantly receiving inhaled tobramycin was undertaken.
A modest increase in FEV 1 over the treatment period 5. If the results generated by the earlier post-hoc analysis are confirmed in this trial, more than people with CF in the UK could stand to benefit from ataluren . As class II mutations are by far the most common, they represent a prime target for precision medicine in CF. Class II mutations result in a misfolded protein that is destroyed by the cell machinery.
The Fdel mutation results in severely reduced expression of the CFTR protein at the epithelial membrane; those channels that do reach the cell surface exhibit disrupted opening.
A two-pronged approach to ameliorate the effect of this mutation has, therefore, been investigated: In both studies there was a statistically significant but modest improvement in the change in FEV 1 percentage predicted from baseline at week 24 mean relative treatment difference 4.
While in itself, this discreet change in absolute FEV 1 percentage predicted is unlikely to be clinically meaningful, this could represent stability in pulmonary function — the outcomes from longer studies to confirm this effect are eagerly anticipated.
This is particularly important because fewer exacerbations would be expected to confer better long-term outcomes. Class III mutations result in expression of impaired CFTR channels at the cell membrane, such that the probability of the channel being open and functioning normally is reduced. Granted a marketing authorisation in July , ivacaftor is a first-in-class CFTR potentiator that acts by increasing the flow of ions through activated CFTR channels by increasing the open probability of the CFTR channel once it has reached the apical cell membrane .
The efficacy of ivacaftor has been demonstrated in several studies. This improvement in FEV 1 was observed after only two weeks of treatment, and was sustained for the week duration of the study.
Of particular note was the statistically significant reduction in sweat chloride in the treated group to a mean of The outcome of this study was arguably the most significant milestone in the management of CF since the identification of the responsible gene: Safety and pharmacokinetics have been studied in children aged 2—5 years, and with exposure to the drug similar to that previously reported, there is every reason to believe ivacaftor will improve the trajectory of disease progression in this age group .
Real-life data suggest similar results are being seen in those treated with the drug in practice, with similarly depressed sweat chloride and improvements in FEV 1 and a low rate of discontinuation .
The ability to depress sweat chloride has since been replicated in phase II studies of a new investigational potentiator, QBW, which is being developed by Novartis Pharmaceuticals Switzerland. RH, a class IV mutation, is an example of a residual function mutation associated with milder clinical manifestation and increased survival, for which ivacaftor has also been evaluated .
With limited investigation into precision medicines for class IV to VI mutations, these may represent particular targets for gene therapy in the future. While advances in precision medicines have the potential to improve outcomes in CF, several challenges also arise.
With high costs, they are already being scrutinised for affordability. They do not necessarily resolve difficulties with adherence to treatments and, as yet, relatively little is known about their long-term effects in people who will in most cases take these treatments for many years. The role of the pharmacist in the management of CF has recently been described and central to the role is an understanding of the current challenges in treating CF . There is an increasing public expectation that all treatments will be made universally available, irrespective of cost.
However, the financial challenge to treating CF in the UK and elsewhere currently seems insurmountable, and is only set to worsen. However, access to newer formulations of inhaled therapies and precision medicines is not standardised throughout the EU . In the UK, access is generally equitable, however, there can be long delays between a medicine being granted a marketing authorisation and being authorised for routine use from central funds.
In this instance, a discount was agreed between the NHS and the manufacturer to improve cost-effectiveness and make it available for prescribing . Whether or not an agreement can be reached over a price that could be deemed affordable to the NHS is yet to be seen. Longer term evaluation of these agents will be required to determine their true ability to modify the course of the disease over many years and indeed long-term cost-effectiveness because the current expectation is that these agents could be prescribed life-long .
Precision medicines, by virtue of high development costs and relatively limited reach when marketed, may attract exorbitant prices. The concept of distributive justice suggests that risks of research cannot be assumed by one cohort, if the cohort is unlikely to benefit from that research.
The Declaration of Helsinki, the ethical framework for medical research involving human subjects, asserts that risk assessment prior to involving human subjects in research must compare the risks and burdens to the individuals and groups involved, with the foreseeable benefits to them and others affected by the condition .
Previously, this principle seemed most relevant to those wishing to study the effects of drugs in subjects in developing nations, whose governments may not be able to afford an intervention after it has been tested in their populations. However, with the advent of precision medicine, the cost of providing expensive interventions to a population post-trial and its affordability by healthcare purchasers is now a universal consideration.
As research should be responsive to the health needs of the host country, post-trial obligations must now be given greater emphasis, not least in CF. This issue may also be helped by the recent recommendation to the Committee for Medicinal Products for Human Use CHMP to revise the current guideline on the clinical development of medicinal products for the treatment of CF, in light of current and anticipated future requirements for effective trial design in CF .
More targeted trial design in CF may permit more robust analysis of cost-effectiveness of new drugs and support policymakers to determine affordability. As interest in developing precision medicines for CF continues to grow and more treatment options reach market, some of the issues relating to cost may, in part, be resolved by a more competitive marketplace.
A well described challenge in patients with CF who are often prescribed a multitude of treatments to ameliorate the disease is adherence to treatments. The reasons for reduced adherence are complex, but are likely to include a combination of factors, which may include lack of time to be fully adherent with a complex regimen, depression and anxiety, and a preference not to take treatments in public e.
Supporting patients to improve adherence is equally complex because no specific intervention has been found to be universally beneficial. Instead, a person-centred approach must be taken to tailor any interventions adopted, which may include prioritisation of treatments based on what the individual perceives to be most important, and employing behavioural strategies . One large retrospective study conducted with records of patients with CF in the United States — using medication possession ratio as a proxy for adherence — found that around half of the sampled cohort filled less than half of their prescriptions, which is consistent with known levels of adherence in other chronic diseases .
It has been demonstrated that there is an association between lower medication adherence and the need for intravenous antibiotics to treat pulmonary exacerbations . Although not statistically significant, this is a reasonably predictable consequence of lower adherence, when it is considered that increasing survival rates are thought to be caused, in part, by advances in treatments available.
Lower adherence to treatments in CF has also been associated with increased healthcare costs . As it has been demonstrated that lower rates of adherence are associated with worse outcomes for individuals and increasing costs, it is possible that targeted adherence support could improve these indices.
While pharmacists are well placed to support adherence monitoring, achieving this is difficult in practice, with more than three-quarters of CF specialist pharmacists in a survey describing inadequate adherence monitoring, associated with limited opportunities for sufficient specialist pharmacist involvement .
Despite the high cost of ivacaftor, surprisingly few studies have established adherence rates to ivacaftor in practice. This reduction in adherence would be likely to confer a reduction in efficacy outcomes. With increased survival, several new issues in the management of CF are emerging. In an ageing population, common age-related conditions, such as hypertension, hyperlipidaemia and associated risk of cardiac disease, and malignancies are becoming new therapeutic challenges.
With increasing longevity also comes an increasing lifetime exposure to drugs, some with cumulative adverse effects; the risk of hearing disturbances and renal impairment observed with aminoglycosides, for example, is greater with higher exposure.
For many drugs, such as the newer agents described herein, any risks associated with long-term treatment have yet to be established. Increasing age and comorbidities often increase the complexity of the treatment regimen and although some evidence suggests that increasing complexity does not necessarily translate into reduced adherence, there are other important issues, such as management of drug interactions and adverse drug reactions.
Those treated with either drug should avoid concomitant treatment with strong CYP3A inducers e. Increasingly, consideration must be given to managing treatments pre-conception and during pregnancy. While some drugs used in the management of CF are supported by a degree of reproductive safety data, little is currently known about the effect of newer agents during pregnancy. As outcomes in pregnancy have been established to be closely related to lung function and stability of lung disease, a balance must be struck between the foetal and maternal risks and benefits to continuing or suspending drug treatments .
Complex regimens — particularly those including genotype-specific medicines or drugs used in special populations e. However, while these have been met with enthusiasm, we need to ensure that high costs do not prevent access to treatment. While studies continue to investigate precision medicines, advances continue to be made with drugs intended to ameliorate the symptoms of CF, particularly pulmonary disease.
Mucus modifiers and antibiotics will remain the mainstay of treatment for individuals with CF for many years to come. As the number of available antibiotics and mucus modifiers increase, further studies will be required to determine which combination s are most appropriate at which point in time, with emphasis on efficacy, tolerability, acceptability and adherence.
CF survival rates in the UK are at an all-time high. With this increased survival, we are seeing an increasing number of individuals with increasingly complex clinical circumstances. In the future, efforts must be focused on supporting adherence to treatments to keep patients with CF well for longer, and make good use of limited healthcare resources. In addition, the affordability of new treatments needs to be taken into account early in the drug development process to protect the viability of conducting studies in the future.
