Understanding Quality Paradigm Shifts in the Evolving Pharmaceutical Landscape: Perspectives from the USP Quality Advisory Group.

Recent changes in the pharmaceutical industry have led to significant paradigm shifts in the pharmaceutical quality environment. Globalization of the pharmaceutical industry, increasingly rapid development of novel therapies, and adoption of new manufacturing techniques have presented numerous challenges for the established regulatory framework and quality environment and are impacting the approaches utilized to ensure the quality of pharmaceutical products. Regulators, industry, and standards-setting organizations have begun to recognize the need to rely more on integrated risk-based approaches and to create more nimble and flexible standards to complement these efforts. They also increasingly have recognized that quality needs to be built into systems and processes throughout the lifecycle of the product. Moreover, the recent COVID-19 crisis has emphasized the need to adopt practices that better promote global supply chain resilience. In this paper, the USP Quality Advisory Group explores the various paradigm shifts currently impacting pharmaceutical quality and the approaches that are being taken to adapt to this new environment. Broad adoption of the Analytical Procedure Lifecycle approach, improved data management, and utilization of digital technologies are identified as potential solutions that can help meet the challenges of these quality paradigm shifts. Further discussion and collaboration among stakeholders are needed to pursue these and other solutions that can ensure a continued focus on quality while facilitating pharmaceutical innovation and development.

Demonstrating the influence of HTA: INAHTA member stories of HTA impact.

A central function of health technology assessment (HTA) agencies is the production of HTA reports to support evidence-informed policy and decision making. HTA agencies are interested in understanding the mechanisms of HTA impact, which can be understood as the influence or impact of HTA report findings on decision making at various levels of the health system. The members of the International Network of Agencies for HTA (INAHTA) meet at their annual Congress where impact story sharing is one important activity. This paper summarizes four stories of HTA impact that were finalists for the David Hailey Award for Best Impact Story.The methods to measure impact include: document review; claims analysis and review of reimbursement status; citation analysis; qualitative evaluation of stakeholders' views; and review of media response. HTA agency staff also observed changes in government activities and priorities based on the HTA. Impact assessment can provide information to improve the HTA process, for example, the value of patient and clinician engagement in the HTA process to better define the assessment question and literature reviews in a more holistic and balanced way.HTA reports produced by publicly funded HTA agencies are valued by health systems around the globe as they support decision making regarding the appropriate use, pricing, reimbursement, and disinvestment of health technologies. HTAs can also have a positive impact on information sharing between different levels of government and across stakeholder groups. These stories show how HTA can have a significant impact, irrespective of the health system and health technology being assessed.

Comprehensive Drug-Class Review Framework for improved evidence-based drug policy and formulary modernization.

Formularies are used by payers to optimize access and ensure the appropriate use of medications. Lack of follow-up and re-evaluation can lead to outdated formularies that are not reflective of current evidence. Formulary modernization, an approach to re-align formularies with current evidence has proven successful. The Ontario Drug Policy Research Network (ODPRN) launched a framework for conducting comprehensive drug-class reviews. This commentary describes the individual components of this framework and lessons learned through completion of 12 reviews between 2013 and 2016. We present the ODPRN drug-class review of treatments for chronic hepatitis B as a case example to illustrate the components and impact. The incorporation of foundational health technology assessment components such as economic evaluations and knowledge synthesis with contextualizing evidence such as patient and clinician perspectives (through qualitative studies), real-world evidence (through data analytics), and cross-jurisdictional comparisons (through environmental scans and data analytics), successfully developed jurisdictionally specific policy recommendations grounded in up-to-date evidence. The ODPRN framework for conducting comprehensive drug-class reviews is a robust and feasible approach to conduct formulary modernization. This framework allows for actionable and specific policies which are likely to be considered by decision makers. Adoption of similar frameworks in other jurisdictions may improve uptake of evidence-informed policy recommendations.

Assessment of methods for determination of glycan composition of erythropoietin.

Erythropoietin (EPO) is a monomeric, highly glycosylated, protein hormone (molecular size around 30-35 kD), produced mainly in adult kidneys, which acts principally on red blood cell progenitors and precursors to promote red cell production. Therapeutic EPO products are widely used biotherapeutics. They are mainly produced by recombinant DNA technology in mammalian cells and their biological activity is closely linked to the degree of N-glycan sialylation. Determination of the sialic acids' content and complexity by glycan mapping therefore appears critical to ensure the quality and efficacy of the EPO therapeutic products. The European Directorate for the Quality of Medicines & HealthCare organised a study (BSP144) under the aegis of the Biological Standardisation Programme to assess N-glycan mapping tests with the aim of incorporating a standard method into the European Pharmacopoeia monograph 'Erythropoietin concentrated solution' (1316). The use of a 'reagent panel' consisting of six EPO preparations with a range of iso-electric properties facilitated comparison between laboratories and methodologies. Based on the study results, a robust and repeatable HPAEC-PAD chromatographic method was identified and work to introduce it in the monograph as an example method has been initiated.

Challenges and Opportunities for Improving the Safety Assessment of Botanical Dietary Supplements: A United States Pharmacopeia Perspective.

The United States Pharmacopeia (USP) is an independent, nonprofit, science-based organization whose mission is to improve global health through public quality standards for dietary supplements, medicines, and food ingredients.1 Before developing standards for dietary supplement ingredients, the USP performs an "Admission Evaluation" (Figure 1), which includes an assessment to ascertain that an ingredient does not present a serious health risk.2 This article discusses the challenges encountered during the evaluation of botanicals and proposes possible solutions.

Coverage for hepatitis C drugs in Medicare Part D.

OBJECTIVES: The recent arrival of new hepatitis C virus (HCV) drugs has brought fiscal pressures onto Medicare Part D; spending on HCV drugs in Part D jumped from $283 million in 2013 to $4.5 billion in 2014. We examined the current benefit designs for HCV drugs in Part D plans and analyzed patients' financial burden for those drugs. STUDY DESIGN: A cross-sectional analysis of CMS' July 2015 Part D Plan Formulary File and the Wolters Kluwer Health Medi-Span Electronic Drug File v.2. METHODS: We analyzed the type and amount of cost sharing for HCV drugs and the extent to which plans apply utilization management tools. We then estimated total out-of-pocket spending for beneficiaries to complete a course of treatment. RESULTS: All Part D plans covered at least 1 recently introduced HCV drug, as of July 2015. Nearly all plans charged relatively high coinsurance and required prior authorization for new HCV drugs. For enrollees with no subsidy, the mean out-of-pocket spending needed to complete a course of treatment is substantial, ranging from $6297 to $10,889. For enrollees with a low-income subsidy, out-of-pocket spending varies between $10.80 and $1191. CONCLUSIONS: Under the current Part D benefits, HCV drug users with no subsidy face sizable financial burdens, even with catastrophic coverage and the recent in-gap discount for brand name drugs. As baby boomers-the group most likely to have HCV-join Medicare, efforts should be made to ensure patient access to these needed drugs.

Long-Term Cost-Effectiveness of Insulin Glargine Versus Neutral Protamine Hagedorn Insulin for Type 2 Diabetes in Thailand.

BACKGROUND: Even though Insulin glargine (IGlar) has been available and used in other countries for more than a decade, it has not been adopted into Thai national formulary. This study aimed to evaluate the long-term cost effectiveness of IGlar versus neutral protamine Hagedorn (NPH) insulin in type 2 diabetes from the perspective of Thai Health Care System. METHODS: A validated computer simulation model (the IMS CORE Diabetes Model) was used to estimate the long-term projection of costs and clinical outcomes. The model was populated with published characteristics of Thai patients with type 2 diabetes. Baseline risk factors were obtained from Thai cohort studies, while relative risk reduction was derived from a meta-analysis study conducted by the Canadian Agency for Drugs and Technology in Health. Only direct costs were taken into account. Costs of diabetes management and complications were obtained from hospital databases in Thailand. Both costs and outcomes were discounted at 3 % per annum and presented in US dollars in terms of 2014 dollar value. Incremental cost-effectiveness ratio (ICER) was calculated. One-way and probabilistic sensitivity analyses were also performed. RESULTS: IGlar is associated with a slight gain in quality-adjusted life years (0.488 QALYs), an additional life expectancy (0.677 life years), and an incremental cost of THB119,543 (US$3522.19) compared with NPH insulin. The ICERs were THB244,915/QALY (US$7216.12/QALY) and THB176,525/life-year gained (LYG) (US$5201.09/LYG). The ICER was sensitive to discount rates and IGlar cost. At the acceptable willingness to pay of THB160,000/QALY (US$4714.20/QALY), the probability that IGlar was cost effective was less than 20 %. CONCLUSIONS: Compared to treatment with NPH insulin, treatment with IGlar in type 2 diabetes patients who had uncontrolled blood glucose with oral anti-diabetic drugs did not represent good value for money at the acceptable threshold in Thailand.

Validation of modeled pharmacoeconomic claims in formulary submissions.

Modeled or simulated claims for costs and outcomes are a key element in formulary submissions and comparative assessments of drug products and devices; however, all too often these claims are presented in a form that is either unverifiable or potentially verifiable but in a time frame that is of no practical use to formulary committees and others who may be committed to ongoing disease-area and therapeutic-class reviews. On the assumption that formulary committees are interested in testable predictions for product performance in target populations and ongoing disease area and therapeutic reviews, the methodological standards that should be applied are those that are accepted in the natural sciences. Claims should be presented in a form that is amenable to falsification. If not, they have no scientific standing. Certainly one can follow ISPOR-SMDM standards for validating the assumptions underpinning a model or simulation. There is clearly an important role for simulations as an input to policy initiatives and developing claims for healthcare interventions and testable hypotheses; however, one would not evaluate such claims on the realism or otherwise of the model. The only standard is one of the model's ability to predict outcomes successfully in a time frame that is practical and useful. No other standard is acceptable. This sets the stage for an active research agenda.

A needle-free reconstitution and transfer system for compounded sterile intravenous drug solutions in compliance with United States Pharmacopeia Chapter <797> standards.

Today's health-system pharmacists and those in independent practice face risks, including exposure to potent cytotoxic drugs via needlesticks, that are associated with preparing intravenous compounded sterile preparations for immediate use. Healthcare givers who administer such medications also risk exposure to needlesticks. Those hazards can be minimized when the pharmacist thoroughly understands and complies with current standard operating procedures for preparing intravenous compounded sterile preparations and the healthcare giver uses a needle-free system for drug reconstitution and administration. The components of an overall needlestick risk-reduction strategy to ensure safety in the preparation (and eventual administration) of intravenous compounded sterile preparations should therefore include the use of needle-free connection and administration devices as well as hand-hygiene training, aseptic technique competency evaluation and training, and the maximum use of commercially available or ready-to-use dosage forms. This article, which focuses on the pharmacist's use of a needle-free reconstitution and transfer system for compounded sterile intravenous drug solutions, uses as an example the Vial2Bag (Medimop Medical Projects, Ltd., [a subsidiary of West Pharmaceutical Services, Inc., Exton, Pennsylvania], Ra'anana, Israel), which complies with United States Pharmacopeia Chapter <797> standards. Features of that system are summarized for easy reference.

WHO Expert Committee on Specifications for Pharmaceutical Preparations.

The Expert Committee on Specifications for Pharmaceutical Preparations works towards clear, independent and practical standards and guidelines for the quality assurance of medicines. Standards are developed by the Committee through worldwide consultation and an international consensus-building process. The following new guidelines were adopted and recommended for use, in addition to 20 monographs and general texts for inclusion in The International Pharmacopoeia and 11 new International Chemical Reference Substances. The International Pharmacopoeia--updating mechanism for the section on radiopharmaceuticals; WHO good manufacturing practices for pharmaceutical products: main principles; Model quality assurance system for procurement agencies; Assessment tool based on the model quality assurance system for procurement agencies: aide-memoire for inspection; Guidelines on submission of documentation for prequalification of finished pharmaceutical products approved by stringent regulatory authorities; and Guidelines on submission of documentation for a multisource (generic) finished pharmaceutical product: quality part.

Adherence to hospital drug formularies and cost of drugs in hospitals in Denmark.

PURPOSE: To investigate adherence rates to hospital drug formularies (HDFs) and cost of drugs in hospitals. METHODS: Data on drugs used during 2010 were analyzed for ten hospitals (two hospitals from each of the five regions), constituting 30 % of hospitals and 45 % of hospital beds in Denmark. Drug use data from individual hospitals were retrieved from the hospital pharmacies. Adherence to the HDFs was analyzed for selected substances characterised by extensive use both in primary and secondary sectors (ATC codes A10, B03, C03, C07, C08, C09, C10, J01, N02, N05 and R03). Within each group, we also identified the drugs constituting 90 % of the volume (= DU90%) and the adherence to the HDF in this segment (Index of Adherence). RESULTS: Substances used by hospitals varied between 598 and 1,093. The proportion of used substances that were on the HDF varied between 14 % and 44 %. University hospitals used a significantly higher total number of substances (median 165 vs. 139, p = 0.019) and cost/DDD [(median 5 vs. 2 Euros, p = 0.033), p = 0.033] in the DU90% segment than the regional hospitals. Index of adherence varied between 43 % and 91 %. For the selected ATC codes, the index of adherence was between 76 % and 100 %. CONCLUSIONS: Adherence to the selected ATC groups was high, which means that the most commonly used substances are included in the HDFs, even though a variation existed. A large variation existed between the hospitals in the number of substances at HDFs.

Australia's 'fourth hurdle' drug review comparing costs and benefits holds lessons for the United States.

Two decades ago Australia introduced an assessment of value as a prerequisite for adding new medicines to its national drug formulary. Australia's program--a "fourth hurdle" process after a drug is assessed for safety, efficacy, and quality--stands in stark contrast to the situation in the United States, where comparing the clinical and economic value of a proposed new drug to those of existing ones only rarely plays a role in the drug coverage determination process. This article describes the role that Australia's Pharmaceutical Benefits Advisory Committee, a statutory independent expert committee, plays in determining which new drugs the government will help pay for in the nation's pharmaceutical benefit program. The program does not directly control drug prices or ration prescription drugs-policy options that are widely opposed in the United States. Australia's program supports patients' access to important, innovative medications deemed to be cost-effective. The US system could benefit if policy makers examined Australia's experience and adopted a comparative clinical and value review suited to the US political and economic landscape.

Quality of evidence in drug compendia supporting off-label use of typical and atypical antipsychotic medications.

Public and private payers use drug compendia to make coverage determinations, yet the quality of evidence they contain has received little scrutiny. We examined compendia citations regarding antipsychotic drugs, an important drug class given their substantial costs and widespread use. Nearly three-fold as many off-label indications were recommended for atypical as for typical agents, a difference that did not appear to be due to differences in quality of evidence for typical and atypical off-label indications. Given the important role that compendia play in evidence synthesis, coverage decisions, and ultimately, prescription utilization, these data suggest greater efforts are needed to improve the quality of evidence and transparency of evidence evaluations compendia contain.
