Good design practices for an integrated containment and production system for advanced therapies.

Advances in molecular biology and the possibility of differentiating stem cells have opened up new scenarios in therapies that use progenitor or variously differentiated cells. Regardless of the choice of the system, designing a plant for producing advanced therapies requires a clear understanding of the final objective (the product), taking into account all the regulatory, environment, process, risk assessment, asepsis, and validation aspects involved until its implementation. Good Manufacturing Practice (GMP) compliant procedures are a prerequisite for cell production in clinical application, and clean rooms are zones for producing cell therapies. Clean rooms for clinical application require high running and maintenance costs and need trained operators and strict procedures to prepare the rooms and the people involved in the processes. While today production mainly occurs in open systems (clean rooms), there is evidence of processes in closed systems (isolators). The isolator is a Grade A aseptic closed system that requires a controlled environment and at least a Grade D environment in the case of sterile productions (A in D closed system). The use of isolators can ensure a very high level of protection against the risk of product contamination and, at the same time, provide the operators with a very safe working environment. Furthermore, working with closed systems can optimize and facilitate the production of Advanced Therapy Medical Products in GMP environments, by providing an easily reproducible working tool even for large-scale production, with generally lower costs compared to a classical clean room approach. In conclusion, the isolator workstation as a possible alternative to the classic clean room, due to its small size and the simplification of the working and maintenance operational procedures, may represent an interesting solution in the perspective of the increasingly more stringent requests for cost reductions of GMP in clinical application.

Challenges with Forecasting Budget Impact: A Case Study of Six ICER Reports.

BACKGROUND: Payers frequently rely on budget impact model (BIM) results to help determine drug coverage policy and its effect on their bottom line. It is unclear whether BIMs typically overestimate or underestimate real-world budget impact. OBJECTIVE: We examined how different modeling assumptions influenced the results of 6 BIMs from the Institute for Clinical and Economic Review (ICER). STUDY DESIGN: Retrospective analysis of pharmaceutical sales data. METHODS: From ICER reports issued before 2016, we collected estimates of 3 BIM outputs: aggregate therapy cost (ie, cost to treat the patient population with a particular therapy), therapy uptake, and price. We compared these against real-world estimates that we generated using drug sales data. We considered 2 classes of BIM estimates: those forecasting future uptake of new agents, which assumed "unmanaged uptake," and those describing the contemporaneous market state (ie, estimates of current, managed uptake and budget impact for compounds already on the market). RESULTS: Differences between ICER's estimates and our own were largest for forecasted studies. Here, ICER's uptake estimates exceeded real-world estimates by factors ranging from 7.4 (sacubitril/valsartan) to 54 (hepatitis C treatments). The "unmanaged uptake" assumption (removed from ICER's approach in 2017) yields large deviations between BIM estimates and real-world consumption. Nevertheless, in some cases, ICER's BIMs that relied on current market estimates also deviated substantially from real-world sales data. CONCLUSIONS: This study highlights challenges with forecasting budget impact. In particular, assumptions about uptake and data source selection can greatly influence the accuracy of results.

Using online content uniformity measurements for rapid automated process development exemplified via an X-ray system.

This paper addresses the relevance of automated content testing for the rapid automated process development (RAPD). Our previous work demonstrated that RAPD allowed a fast and efficient development of a continuous capsule-filling process. Target was the mean weight and the relative standard deviation of the weight. Likewise important are the content and the content uniformity. However, an implementation demands a certain level of automation. In general, technology is available that can detect active pharmaceutical ingredient (API) inside the capsules but the final application is linked to additional development and investment in machinery. To eliminate doubts regarding the benefits of an automated content check within the RAPD we present an application example. First, an X-ray system was used to detect barium sulfate accurately inside capsules. Second, a process was developed where barium sulfate was filled. The concentration of excipients was modified in the experiments, as well as the setting of the process parameter. The obtained model provided an explicit understanding of the process. Subsequently, the content uniformity model was compared to a model of the capsule weight relative standard deviation, confirming the benefits of an automated content check in the RAPD. Moreover, we presented another example illustrating the advantages of a connected continuous filling process, which permits evaluation of all process steps and their interactions (i.e. evaluation of the entire process).

The Impact of the National Institute for Pharmaceutical Technology and Education on Academic Research.

Surveys of institutional representatives of member institutions and faculty members engaged in the National Institute for Pharmaceutical Technology and Education (NIPTE) revealed that NIPTE is having a positive impact on academic research in the area of pharmaceutical technology by aligning research directions with FDA needs, by providing funding that may not be available elsewhere, and by creating a collegial and collaborative relationship among researchers in this area from various institutions. NIPTE is contributing to the viability of pharmaceutics and pharmaceutical engineering research in academic settings. Some responders cite the fluctuations in funding and relative low levels of funding received as a problem in maintaining programs, but most perceived a positive impact.

Situation analysis of procurement and production of multiple micronutrient supplements in 12 lower and upper middle-income countries.

Globally, there are few vitamin and mineral ingredient manufacturers. To support local, in-country or regional procurement and production of multiple micronutrient supplements (MMS), the following production scenarios are possible: (a) straight ingredients of vitamins and minerals forms imported or locally produced that are mixed, tableted, or encapsulated and packaged by a local manufacturer; (b) import or local production of a vitamin and minerals premix that is tableted or encapsulated and packaged locally; (c) import of a bulk, finished product (tablets or capsules) that is packaged and branded; and (d) or import of a branded packaged product. This paper is a situation analysis of the market, manufacturing, and policy factors that are driving the production of MMS in 12 lower and upper middle-income countries. Key informants completed a self-administered structured questionnaire, which examined the local context of products available in the market and their cost, regulations and policies, in Brazil, Colombia, Guatemala, Mexico, Peru, Bangladesh, India, Vietnam, Ghana, Kenya, Nigeria, and South Africa. Our study found that although most countries have the capacity to produce locally MMS, the major barriers observed for sustainable and affordable production include (a) poor technical capacity and policies for ensuring quality along the value chain and (b) lack of policy coherence to incentivize local production and lower the manufacture and retail price of MMS. Also, better guidelines and government oversight will be required because not one country had an MMS formulation that matched the globally recommended formulation of the United Nations Multiple Micronutrient Preparation (UNIMMAP).

Good manufacturing practices production of a purification-free oral cholera vaccine expressed in transgenic rice plants.

KEY MESSAGE: The first Good Manufacturing Practices production of a purification-free rice-based oral cholera vaccine (MucoRice-CTB) from transgenic plants in a closed cultivation system yielded a product meeting regulatory requirements. Despite our knowledge of their advantages, plant-based vaccines remain unavailable for human use in both developing and industrialized countries. A leading, practical obstacle to their widespread use is producing plant-based vaccines that meet governmental regulatory requirements. Here, we report the first production according to current Good Manufacturing Practices of a rice-based vaccine, the cholera vaccine MucoRice-CTB, at an academic institution. To this end, we established specifications and methods for the master seed bank (MSB) of MucoRice-CTB, which was previously generated as a selection-marker-free line, evaluated its propagation, and given that the stored seeds must be renewed periodically. The production of MucoRice-CTB incorporated a closed hydroponic system for cultivating the transgenic plants, to minimize variations in expression and quality during vaccine manufacture. This type of molecular farming factory can be operated year-round, generating three harvests annually, and is cost- and production-effective. Rice was polished to a ratio of 95 % and then powdered to produce the MucoRice-CTB drug substance, and the identity, potency, and safety of the MucoRice-CTB product met pre-established release requirements. The formulation of MucoRice-CTB made by fine-powdering of drug substance and packaged in an aluminum pouch is being evaluated in a physician-initiated phase I study.

Which factors enhance positive drug reimbursement recommendation in Scotland? A retrospective analysis 2006-2013.

OBJECTIVES: To identify the factors that influence the Scottish Medicines Consortium (SMC) in deciding whether to accept pharmaceutical technologies for use within the Scottish health care system. METHODS: A database of SMC submissions between 2006 and 2013 was created, containing a range of clinical, economic, and other factors extracted from published health technology assessment reports. A binomial outcome variable was used, defined as the decision to "accept for use" or "not recommend" a technology. Univariate and multivariate analyses were conducted to assess the impact by means of odds ratios (ORs) of the submitted evidence on the recommendation decision. RESULTS: Out of 463 applications, 265 were accepted for use (57%) and 198 (43%) were not recommended for use within National Health Service Scotland. Univariate analyses showed that 13 variables significantly affected the SMC decision. Of these 13 variables, 7 variables were shown to have a meaningful impact in the multivariate analysis. Four of these concerned the outcome of cost-effectiveness analyses; the fact that a submission was supported by a cost-minimization analysis was the strongest positive variable (OR = 10.30) and a submission showing a product not being cost-effective (i.e., incremental cost-effectiveness ratio above £30,000/quality-adjusted life-year gained) was the strongest negative predictor (OR = 0.47). The other variables concerned whether the submission was related to a product indicated for a nervous system disease (OR = 0.41), whether it was indicated for nonchronic use (OR = 1.66), and whether the submission was performed by a big company (OR = 2.83). CONCLUSIONS: This study demonstrated that the outcome of cost-effectiveness analyses is an important factor affecting the SMC's reimbursement recommendation decision.

The Impact of Serialisation on Operational Efficiency and Productivity in Irish Pharmaceutical Sites.

Technology enabling drug serialisation technology was introduced by regulators to enhance security in pharmaceutical supply chain and protect drugs from infiltration by falsified and substandard medicines. The introduction of systems for serialisation required huge financial outlays manufacturers of pharmaceuticals. This study investigated the impact of serialisation on the operational efficiency and productivity in Irish pharmaceutical sites. A qualitative study was conducted with 11 manufacturing sites in Ireland. The participating companies operated a total of 114 pack-lines, representing approximately 65% of the automated packing lines in the country. The study found that serialisation had a negative effect on packaging production line OEE and line availability and on the individuals cost per unit of packaged pharmaceuticals. The research results estimated that the capital costs of serialisation were four times greater than those estimated by the regulators. There was a 4.1 cents average cost per pack for serialisation with high volume sites reporting an annual cost of serialisation of up to €4.5 m per annum and a 2.7% increase in the average cost of goods sold. A pattern whereby where many pharmaceutical manufacturers are transitioning from smaller batch production and moving toward larger batch production sizes in order to increases efficiencies was identified. The research also proposed the use of a serialisation depreciation factor as a method to determine the impact of serialisation on the cost of goods sold. This is the first study of its kind into the cost of serialisation from a manufacturer's viewpoint and studying the effects of serialisation on productivity, line availability and operational efficiency.

Realising the value of plant molecular pharming to benefit the poor in developing countries and emerging economies.

Molecular Pharming, the production of recombinant pharmaceuticals through plant biotechnology, has the potential to transform the biologics sector of the pharmaceutical industry. More fascinating however, is how it might be used to improve access to modern medicines, and improve health of the poor in developing countries and emerging economies. Although improving global health through molecular pharming has been discussed for at least two decades, little progress has actually been made. In this manuscript, a four point plan is described to maximise the opportunity for molecular pharming to provide solutions. These are (i) to identify and prioritise important drug targets that are relevant to the poor; (ii) to support research and development partners in low to middle income countries to develop local expertise, transfer technology and build capacity; (iii) to increase collaboration between regulatory bodies to enable national regulatory frameworks to be developed in low to middle income countries; and (iv) to promote intellectual property management approaches that include socially responsible licensing. An existing case study is described to illustrate how this might be achieved.

Attempt to increase the transparency of fourth hurdle implementation in Central-Eastern European middle income countries: publication of the critical appraisal methodology.

BACKGROUND: In middle income countries the number of trained health technology assessment specialists is limited and the public budget for health technology assessment is considerably lower compared to developed countries. These countries therefore must develop their own solutions to improve the quality and efficiency of health technology assessment implementation in reimbursement decisions. Our study aimed to develop a scientifically rigorous and detailed appraisal checklist for economic evaluations of pharmaceuticals in the single health technology assessment process. METHODS: The research design entailed a review of economic evaluations, submitted for reimbursement of pharmaceuticals, by two independent academic reviewers to identify the most common methodological problems. Fifty economic evaluations submitted in 2007-2008, randomly selected by the Health Technology Assessment Office served as data sources. The new checklist was developed by an iterative working process: first by assessing ten economic evaluations, then improving the checklist by generating new question items, then employing the improved checklist to assess the next ten economic evaluations. After appraising 25 documents, the reviewers reconciled their opinions and improved the checklist with the researchers of the Health Technology Assessment Office during an expert panel discussion. The reviewers scrutinized the second 25 economic evaluations, after which the expert panel finalized the checklist with consensus. RESULTS: The final checklist consists of 91 yes or no questions in 11 main topics concerning comparator selection, efficacy, effectiveness, costs, sensitivity analysis, methodological approach, transparency, and interpretation of results. The new checklist is based on current Hungarian evaluation practice. As the published checklist will be part of the official single health technology assessment process of pharmaceuticals, submitters will be able to assure the quality of their economic evaluation. CONCLUSIONS: The transparent critical appraisal method should improve the consistency of pharmaceutical reimbursement decisions and facilitate the utilization of economic evaluations in other fields of health care decision-making in other Central-Eastern European countries.

Emergence of biopharmaceutical innovators in China, India, Brazil, and South Africa as global competitors and collaborators.

Biopharmaceutical innovation has had a profound health and economic impact globally. Developed countries have traditionally been the source of most innovations as well as the destination for the resulting economic and health benefits. As a result, most prior research on this sector has focused on developed countries. This paper seeks to fill the gap in research on emerging markets by analyzing factors that influence innovative activity in the indigenous biopharmaceutical sectors of China, India, Brazil, and South Africa. Using qualitative research methodologies, this paper a) shows how biopharmaceutical innovation is taking place within the entrepreneurial sectors of these emerging markets, b) identifies common challenges that indigenous entrepreneurs face, c) highlights the key role played by the state, and d) reveals that the transition to innovation by companies in the emerging markets is characterized by increased global integration. It suggests that biopharmaceutical innovators in emerging markets are capitalizing on opportunities to participate in the drug development value chain and thus developing capabilities and relationships for competing globally both with and against established companies headquartered in developed countries.

How much is the life of a cancer patient worth? A pharmaco-economic perspective.

WHAT IS KNOWN AND OBJECTIVE: Countries struggle to accommodate the introduction of new effective cancer medicines, while containing costs. Our objective is to comment on several pharmaco-economic challenges involved in determining the value of cancer medicines by reviewing cost-effectiveness thresholds for cancer medicines in several countries and by discussing the cost-effectiveness of anti-cancer biotechnology and orphan medicines. COMMENT: A literature search was carried out of PubMed, Centre for Reviews and Dissemination databases, Cochrane Database of Systematic Reviews and EconLit up to August 2009. Health technology assessment agencies in England and Scotland are willing to incur a higher cost per quality-adjusted life year for cancer medicines than for other medicines. Risk-sharing arrangements have been implemented to optimize the value of cancer medicines. The cost-effectiveness of biotechnology medicines in cancer care is challenged by their high price, and depends on the ability to identify the most responsive target population, through use of suitable biomarkers. The evaluation of orphan medicines in cancer care needs to balance the absence of an alternative therapy for a life-threatening disease against the high cost-effectiveness ratio, and usually weak clinical data. WHAT IS NEW AND CONCLUSION: Current strategies used to inform decisions on the funding of expensive anti-cancer medicines are commented on to highlight important issues and problems. Pharmaco-economic evaluation is an important tool for assessing the value of cancer medicines and to inform evidence-based decision making in cancer care. Value-judgments such as preferential consideration of anti-cancer medicines can then be made explicitly.

Exclusivity strategies and opportunities in view of the Biologics Price Competition and Innovation Act.

Government-provided exclusivity periods provide pharmaceutical companies with incentives to invest in new drugs. Meanwhile, encouraging competition serves another worthy goal of improving the affordability of medications. Decades ago, the Hatch-Waxman Act set forth provisions attempting to balance these objectives in the context of small-molecule drugs. Recently, the Biologics Price Competition and Innovation Act was enacted to meet similar aims in the context of biologic drugs. This article presents a detailed comparison of these two Acts. While the Acts share many global similarities (e.g., providing exclusivity terms and abbreviated approval processes), many differences are also apparent when analyzing details of the provisions. One area of great departure between the Acts is the requirements of how a generic or follow-on applicant must address patents covering a reference product. After describing these differences, the article presents predictions of how reference product sponsors will adapt their patent-prosecution strategies in view of the new Biologics Act.

Developments and opportunities in continuous biopharmaceutical manufacturing.

Today's biologics manufacturing practices incur high costs to the drug makers, which can contribute to high prices for patients. Timely investment in the development and implementation of continuous biomanufacturing can increase the production of consistent-quality drugs at a lower cost and a faster pace, to meet growing demand. Efficient use of equipment, manufacturing footprint, and labor also offer the potential to improve drug accessibility. Although technological efforts enabling continuous biomanufacturing have commenced, challenges remain in the integration, monitoring, and control of traditionally segmented unit operations. Here, we discuss recent developments supporting the implementation of continuous biomanufacturing, along with their benefits.
