The drug shortage situation – EIPG’s point of view

by Maurizio Battistini

The shortage of medicines has been a major concern in the countries of the European Union, and elsewhere, for more than 10 years, so much so that the Economic Community has devoted a great deal of effort and increasing attention to this problem in an attempt to mitigate its impact on patient health.

Several factors can be identified as being at the root of the shortage of medicines, some of which intersect with each other, mainly concerning aspects with technical, qualitative, regulatory, forecasting, supply, speculative and economic implications.

EIPG has made its contribution to the various attempts to contain the phenomenon by participating in task forces, round tables and convenings dedicated to identifying the root causes of the issue and, through gap analysis, the consequent mitigation measures. Overall, strengthening the risk-assessment approach to assess and define the risk level of individual deficiencies or the causes to which they pertain in order to rationalize and focus mitigation interventions and identify their level of acceptance with a proactive approach.

Before defining the particularly deserving aspects to be emphasised and consequently acted upon, it is important to mention those that represent, in the opinion of EIPG, but are not limited to, the elements on which priority action should be taken. In analysing the problem, one cannot in fact fail to take proper account of the fact that medicines are not such without their active ingredients and that, for diseases with the widest spread, there are equivalent medicines and alternative therapies. On the basis of the latter assumption, it is understandable that the definition of a shortage of medicines should be restricted to cases where no equivalent medicines or alternative therapies with different medicines are available, so as to concentrate efforts to solve the problem only on those conditions that are worthy of attention because they are not limited to the unavailability of a specific product or to situations for which it is possible to identify an alternative treatment (defining a list of critical medicines and defining risk assessment criteria for assessing whether a product should be on the list or not).

The operation required to bring the production of active ingredients back to Europe, recognising their strategic and central role in the composition of medicines for the entire community and patients, takes longer. The relocation of the manufacturing of active ingredients to third countries, which has been taking place for several years now for mainly economic reasons, has led to the dependence of many other countries, including mainly those of the Union, on supplies that today has the occasional impact that we know of, but which could become much more serious if not systemic. We have been hearing about reshoring the production of active pharmaceutical ingredients for some time now, but so far there do not seem to be any concrete initiatives for its implementation.

As mentioned above, EIPG identified the revision of the definition of drug shortages and the reallocation of strategic production of active pharmaceutical ingredients in Europe as a main key action to mitigate the impact of drug shortages.

Although it is not an aspect of primary interest to the European industrial pharmacist community, EIPG recognises the economic aspects as playing an important role in the origin of shortages, particularly with regard to the low price paid for certain categories of medicines, which induces manufacturers to abandon the manufacture of low-profit products, and the discrepancies in the price of medicines that exist in the different countries of the Union, discrepancies that, coincidentally, make the countries where prices are the lowest or even where volumes are not so attractive as to devote production to shortages.

Having made this necessary digression on the aspects requiring corrective action at source, there are, however, other, mostly ‘occasional’ causes on which to intervene, where possible, in a proactive manner or by means of reaction instruments capable of reducing the impact of shortages. In this regard, some of the elements covered in the introductory part of this discussion, namely: technical-qualitative, regulatory, forecasting and speculative, are taken up and detailed.

As far as the technical quality aspects are concerned, given the vastness of such occasional events in the production cycle of a medicine, a separate, dedicated discussion should be devoted to them. In addition to a few examples, please refer to the chapter ‘Shortages Originating from Manufacturing‘ in the text ‘Pharmaceutical Supply Chains – Medicines Shortages‘ published by Springer and written by the same author as this article. The book, authored by experts in the field, provides an insight of relevant case studies and updated practices in Pharmaceutical Supply Chains (PharmSC) while addressing the most relevant topics within the COST Action Medicines Shortages (CA15105) and it covers uncertainty and risk aspects of supply chain management, carefully combining the scientific level with a pedagogical approach. In industry, proactive strategies such as the adoption of reserve stocks or back-up establishments can be adopted to make up for medicine shortages on an emergency basis, although the expense of sustaining these prudential approaches remains the main problem.

In a number of situations, shortages can occur due to underestimated sales forecasts or problems with the supply of raw materials, and in particular APIs.

A particular case in point is parallel trade, which by its very nature can have such contrasting effects that it has been dubbed ‘The double face of the parallel trade’. While on the one hand, this method is useful in dealing with shortages in a relatively short time (import in the country where the shortage needs to be filled and export from the country where the availability exists), on the other hand, it has often encouraged the migration of products from countries where they are cheap to others where they guarantee a higher margin, in which case it could be the source of the problem and not its solution.

Last but not least, it should be pointed out that the phenomenon of shortages has an economic implication, as it is more likely to affect drugs with low profitability or movements of drugs from countries with low margins or sales volumes to those with high margins or higher market shares.

Heads of Medicines Agencies and the European Medicines Agency on improving availability of human and veterinary medicines invited the EIPG to attend the key stakeholders’ table at the Workshop on Shortages Prevention Plan held on 1 and 2 March 2023. The EIPG was represented by Jane Nicholson and Maurizio Battistini. Staff from the EMA, the European Commission and members of national authorities presented their current initiatives and future plans. Representatives from the research and generics industry, wholesalers, pharmacists from the EIPG and PGEU, and several organizations representing patient groups had the opportunity to present and discuss ideas for shortage prevention, permanent market withdrawals, and shortage communication and transparency.

The meeting had breakthrough sessions on biosimilars (the EMA is publicly encouraging their use) immunoglobulins and veterinary medicines. The EIPG commented on the low prices of medicines that cause shortages and called for more accurate definitions of ‘medicine shortages’ and to focus efforts on essential product shortages where there is no equivalent medicine or alternative therapy to ensure patient access to adequate treatment.

Shown below is the action plan that EIPG submitted to the group at the meeting; an action plan that largely reflects what is the topic of this article.

  • Establish pro-active risk management plan
  • Prepare list of medicinal products of clinical importance that lack therapeutic alternatives • Undertake regular checks on market availability of alternative products especially those with low pricing due to cap measures
  • Criticality in the procurement of all starting materials with particular attention to APIs
    • How to mitigate?
  • Quality and manufacturing aspects that could have an impact on medicines’ shortages
    • How to manage them preventively?
  • Appropriate agreements on quality and capacity of CMOs
  • Need to review quality management systems throughout life cycle (including those for older products)
  • Consideration of batch release and transportation impact on the time to deliver products to the market
  • Review impact on production planning of potential weaknesses in sales forecasting

Everyone in industry agrees that problems of shortages are complex with no quick solutions, and it was interesting to hear staff from Agencies agree that one of the main problems of shortages for older products is the impact of low pricing of products by national healthcare systems. Also, product dumping of medicines at an extremely low price was mentioned as occurring in some countries and everyone present agreed this must not be tolerated. There were 100 participants in the main meeting room at the EMA and 200 who were connected online.

In opening the meeting, Emer Cooke Executive (Director EMA) explained the aim was to inform stakeholders about the HMA/EMA Task Force activities and deliverables and share stakeholders’ perspectives on ongoing and planned initiatives to address availability issues. She explained the long-term position of the EMA is to focus on prevention and to become more proactive, particularly since the EMA after Covid was given an extended mandate for emergency situations. The EU joint action for shortages has been launched to improve capacity at national level and the single point of contact (SPOC) working party is really helping to ensure suitable structures are in place to assist with shortages. The EMA is working with the European Commission, DG SANTE (medicinal products unit, quality, safety and innovation) and DG HERA (intelligence gathering, analysis and innovation unit) both of whom made presentations during the meeting.

In October 2023, released documents about Commission steps up actions to address critical shortages of medicines and strengthen security of supply in the EU.

The work done by the European community is aimed at addressing the shortages of the most critical medicines by emphasising the role of logistical aspects but overlooking certain critical elements that go beyond supply chain management and concern the upstream management of the concrete problems for which medicine shortages continue to occur (root causes). For the time being, the Commission seems to be oriented towards a predominantly top-down approach, even if there are spaces where opportunities for a multidisciplinary discussion involving all stakeholders in the supply chain are offered. However, it remains important to note that the Community is taking an active interest in the problem albeit adopting containment measures aimed at containing the problem rather than solving it at its root.

Given the role entrusted to Italy to find solutions to this important problem, the author is convinced that the face-to-face meeting that EIPG will have in Rome with the Italian Medicines’ Agency, on the occasion of the EIPG’s Annual General Assembly, will serve as a constructive basis for working together to find longer-term solutions to medicines’ shortages main causes.

How to approach drug substance supply in new product introduction (NPI) processes

A key issue to be faced during pharmaceutical development refers to the supply of the active pharmaceutical ingredients and other raw materials to be used for the manufacturing of the first batches of investigational medicinal products, and then up to commercial production once approved.

Changes of specifications can frequently occur during experimentation, thus leading to the need to modify supply requirements for clinical programs. This is more true when dealing with biopharmaceutical investigational products, for which the traditional models for forecasting and demand processes may prove unfitted. The result is a lower robustness and predictability at early stages of the new product introduction (NPI) manufacturing processes. The complexity of the NPI supply chain is also impacting on manufacturing operations, with possible delays in the clinical program and launch schedule.

These issues have been addressed in the document “Guidelines for materials introduction supporting drug substance delivery”, published by the B2B organisation BioPhorum. A summary of its contents has been published in Bioprocess Online.

A good internal communication is fundamental

The ability to produce robust supply forecasts for new product introduction bases on a detailed knowledge of the planning of different activities to be run for a timely launch. Role and responsibilities have to be clear, as well as the information to be collected and timely shared between the manufacturing and commercial departments of biopharmaceutical companies.

The availability of such information is crucial to reduce the variability intrinsic in the NPI process for a biopharmaceutical product, which costs much more compared to a traditional smallmolecule based one. Reducing variability also impacts on the ability to better compete in the often highly dynamic market for biosimilars, or to address the launch of a new biotherapeutic under the correct perspective. Issues may be encountered also with respect to the regulatory approval processes, which may require different time lengths in different geographic areas or countries. This adds another uncertainty factor to estimates of the quantities of product to be manufactured.

Upon this considerations, the BioPhorum document identifies four key issues to be addressed to provide for a timely NPI process, including capacity and lead-time restrictions or oversupply, late change evaluation and implementation, governance issues and network complexity and in-licensed (or non-platform) products.

The availability of a good NPI process may avoid to incur many problems once operations are in place; all the needed master data information to support the use of raw materials should also be present and correct. BioPhorum’s suggestion is to include NPI processes in the creation of master service and supply agreements for the supply of raw materials, as they help to reach clarity on what a supplier can deliver and what it cannot.

A four steps methodology and roadmap

The document by the BioPhorum describes the results of a project aimed to develop a materialsbased methodology and roadmap to support improved NPI processes, on the basis of a collaborative industry approach to identify and implement best practices.

The result is a four steps process referring to the different activities needed to set up materials introduction and supply. The proposed different steps include the establishment of product lifecycle materials requirements, materials evaluation, supplier selection and qualification, and a manufacture and business review. Each of them should be supported by specific tools and checklists to be developed internally by the company. The governance of the process should involve senior supplier/manufacturer nominees to formally approve the package of deliverables at each stage gate.

Establishing product lifecycle material requirements

For each of the four steps of the NPI process, the BioPhorum document offers detailed lists of information to be collected and of expected outcomes.

Stage gate 1 addresses the establishment of product lifecycle material requirements, usually corresponding to the activation of first time in human studies (FTIH). Data to be collected include specifications of raw materials (e.g. order of magnitude, grade, supply options, environmental-health-safety (EHS) or geographic issues, etc.) as well as master data such as recipe information, plant diagram, list of equipment and process information. At the clinical level, information on the demand sensitivities on indication and clinical milestones and decision points should support the first estimates of the supply and demand plan, to be then expanded to agree on lifecycle forecasts.

The output may take the form of a ‘Product Lifecycle Demand and Supply Strategy’, a document discussing the long-term supply, demand and manufacturing of the product. Starting from the initial planning, the strategy should evolve through the creation of a data store specific for biopharmaceuticals, and the execution of gap analysis for in-licensed products. The strategy should also include a rough capacity modelling and description of ownership and the definition of a RACI matrix (responsible, accountable, consult, inform) to clarify roles and responsibilities with respect to each task, deliverable, or action. Information should be also available on high level technology requirements (both at the internal and external level). Strategic suppliers should be involved in early activities and materials risk analysis should be initiated.

Materials evaluation

Stage gate 2 refers to the information to be gathered from suppliers on the basis of requests for information (RFI) on materials. This should include all the different aspects relevant to the selection of the supplier, including capacity and costs, contacts, technical specifications and audit history, availability of samples, EHS aspects and business systems (e.g. availability of an appropriate ERP system).

This information should facilitate the identification of supplier that might be able to support the predicted or proposed growth of the product over its lifecycle. Stage gate 2 is also part of the risk management process to be run to validate the activation of full production.

Outputs include the sharing of forecasts and sensitivities with suppliers as needed, the establishment of a standard industrial master data set for biopharmaceuticals, as well as of business acceptance criteria.

Supplier selection and qualification

Stage gate 3 addresses the qualification process to finally select the most suitable suppliers and close the corresponding material supply agreements. The RFI and other information gathered in the previous step represent the basis of this exercise, aimed to develop a supply chain resilience strategic approach. The signature of the initial contracts is the final mark of formal selection, and should be supported by an agreement with the supplier on forecast and schedule for the supply, as well as of the business acceptance criteria.

Manufacture and business review

Stage gate 4 refers to the assessment of the operational performance of the supply chain for raw materials, a key activity in order to ensure continuity of supply and to promptly intercept any emerging issue on the basis of trends analysis.

Tools needed to this instance include the definition of appropriate metrics to monitor supplies (e.g. adherence to schedule, “On time in full”-OTIF, “Cost of poor quality”-COPQ). Information on the innovation potential of the supplier and the provision of a feedback on its performance is also deemed important. Any issue should be timely discussed between the supplier and the biopharmaceutical company, and confirmation of the production schedule agreed upon.


Investing in formulation as success’ factor

by Giuliana Miglierini

Formulation is a critical step in the development of new medicinal products, as it directly influences the bioavailability, release profile and stability of the active ingredient, overall impacting on both the efficacy and safety of the medicine.

While in the traditional approach the definition of the final formulation was a quite late step along the development process, new models of R&D greatly focus on early formulation as a way to optimise both time and costs of drug development. It is thus important to identify the optimal formulation strategy as early as possible: a quite challenging goal in many instances, especially in the case of last generation complex biopharmaceuticals which may prove difficult to formulate. An article by Felicity Thomas, published in Pharmaceutical Technology discusses how to address early formulation strategies to maximise the chance of success.

Limits and challenges of formulation

The main objective of the drug development process remains the same, reducing as much as possible the time-to-market so to fully exploit the marketing exclusivity period granted by the patents protecting an innovative medicine.

To this instance, some key aspects should be considered in order to rapidly establish the most appropriate formulation, with a special attention to achieving an early access to first-in-human assessment and proof-of-concept studies.

Scaling-up of the formulation process is another critical issue, as it requires a careful consideration of all the steps needed to establish the final manufacturing process at the commercial scale. This exercise is fundamental in order establish the critical quality attributes and process parameters, thus reducing the risk of a change of the initial formulation to make it suitable to the final manufacturing process.

As explained by Jessica Mueller-Albers, strategic marketing director Oral Drug Delivery Solutions, Evonik, the increased pressure to speed up formulation is also connected to the fact “many new drugs target small therapeutic areas, where it is essential for pharma companies to be first in the market from an economic perspective.”

The availability of enabling technologies is fundamental to early formulate niche medicinal products, moving away from the classical mass production. The trend initiated with the development of mRNA Covid-19 vaccines may represent a change of paradigm in drug development, suggests Jessica Mueller-Albers. Lipid nanoparticles (LNPs) are an example of enabling technology that has been widely employed to formulate the mRNAs used in Covid-19 vaccines. LNPs may take many different forms, i.e. liposomes, lipoplexes, solid lipid nanoparticles, nanostructured lipid nanoparticles, microemulsions, and nanoemulsions (see more in Drug Development and Delivery).

Other types of emerging technologies are also widely investigated, such as proteolysis-targeting chimeras (PROTACS). These are heterobifunctional nanomolecules, containing one moiety recognised by the E3 ligase and chemically linked to a ligand (small molecule or protein) able to bond to the target protein. The final outcome is the formation of a trimeric complex, through which it becomes possible to transfer ubiquitin molecules to the target protein. The mechanism represents an alternative approach to “knock down”, as it enables the degradation of the target protein, offering many advantages compared to the use of classical inhibitors.

Another challenge to be faced during formulation development is the need of a broad and specialised expertise in the different domain of drug development, including also material characterisation, drug metabolism and pharmacokinetics. According to Stephen Tindal, director, Science & Technology, Europe, Catalent, this is particularly true for small companies, which are often the focus of early development activities before acquisition of the projects by larger multinationals. As explained in the Pharmaceutical Technology’s article, a possible approach is to use small teams of experts to manage the preclinical phases of development.

The many challenges of early formulation

The solubility of the active pharmaceutical ingredient (API) in aqueous media is often one of the main challenges to be faced in formulation studies, impacting also on the final bioavailability of the drug in the target body compartments and/or fluids. Estimates indicates that at least 70% of new APIs are poorly soluble.

Other challenging points to be taken into consideration include the possible presence of different polymorphic forms, each characterised by its own stability and properties, and potentially giving rise to conversion from one another during the formulation and/or manufacturing process (see more in the article by A. Siew, Pharmaceutical Technology). The often limited amount of API in the early phases of development and the difficulty to evaluate the dose range on the basis of the available data are other critical point to be considered.

The development of an appropriate bioavailable formulation is often based on preclinical data obtained from animal pharmacokinetic and GLP toxicity studies, followed by pre-formulation studies to assess API’s properties (e.g. solubility, stability, permeability, etc.) in commonly used solvents and bio-relevant media. Drug delivery systems might be used to solve solubility issues, to then scale the identified formulation on the selected technology platform to be used for manufacturing (see more in Drug Development and Delivery).

The principles of the Developability Classification System (DCS) may be also considered to better assess the physicochemical and biopharmaceutical characteristics of a new API that may impact of the formulation process.

Some possible approaches to early formulation

The experts interviewed by Felicity Thomas have indicated some possible approaches useful to addresses formulation issues. For systemic oral small-molecule drugs, for example, the use of a solution as the delivery vehicle may allow to reduce the needed amount of API, thus supporting lower costs to reach Phase I proof of concept in healthy volunteers. Various techniques are also available to favour solubilisation and bioavailability of the active ingredient, i.e. hot-melt extrusion, spray drying, coated beads, size reduction, lipid-based approaches, etc. The optimisation of particle size by mean, for example, of micronisation and nanomilling techniques is another option. Co-administration with lipids can enhance the lymphatic transport of lipophilic drugs, as it favours its incorporation into chylomicrons at the intestinal level, and the subsequent delivery to the lymphatic system in the form of chylomicron–drug complexes.

Many algorithm-based platforms and predictive models are also available to support formulators in the selection of excipients and solubilisation methods, avoiding the need of extensive testing. The implementation of real-time adaptive manufacturing is another possible tool, useful to optimise the formulation on the basis of emerging clinical data.
