    In March 2020, the European Commission requested an updated opinion from the European Food Safety Authority (EFSA) on titanium dioxide's safety. Although EFSA's 2016 opinion found no immediate safety concerns, it noted data gaps, especially regarding particle size, which can affect its toxicological properties. The new EFSA opinion from May 2021 doesn't definitively label E171 as harmful but doesn't dismiss health risks like genotoxicity. Since the safety cannot be confirmed, the European Commission (EC) banned titanium dioxide (E171) as a food additive in the EU, starting with a six-month phasing out period from Feb. 7, 2022, to Aug. 7, 2022, after which a full ban applied.

    Conducting stability studies is a critical aspect of the drug development process, as the information gained determines key clinical development decisions and becomes an essential component of the submission package required by regulatory authorities globally. For any biological therapy, there is a set of attributes that is critical to maintaining the product’s safety and efficacy; the purpose of stability studies is to analyze these attributes at predetermined timepoints during the study to understand how they may be impacted by storage in different environmental conditions. Through understanding the links between storage and product degradation that may give rise to loss of biological activity, possible toxicity or unwanted immunogenicity that pose potential risk to patient health, stability studies generate the data necessary to specify the storage conditions required to maintain product quality and safety and justify the shelf life and expiration dates for your biological product.

    Container closure integrity (CCI) is fundamental for maintaining the sterility and stability of sterile injectable products. Regulators are therefore requiring the execution of robust CCI studies that generate data throughout the product life cycle. This will support the choice of appropriate primary packaging components, help qualify the process to fill and assemble container systems with good CCI, and help demonstrate the maintenance of CCI during transport & storage as well as over shelf life. Regulatory guidance revisions on the topic of CCI include a United States Pharmacopeia (USP) chapter implemented at the end of 2016, USP , the ongoing revision of the EU Annex 1, as well as new guidance from the regulators in China and Japan. Robust studies generating science-based CCI data to help meet these new guidances require appropriate CCI test (CCIT) methods. The language used in the slides presented in Figure 1 is an example of how regulators are asking for improved CCI test methods. The methods should be specific for the product-container closure system and should preferably move away from the traditional probabilistic tests to deterministic ones which generate analytical data and can be validated for detecting critical leaks.

    Course Overview: Stability testing is a major requirement in the development of a pharmaceutical product to determine the versatility of a drug substance when exposed to certain conditions such as heat, pH, humidity, and radiation. It is vital for patient safety to know how a drug product will change over time and to provide adequate advice for the storage and disposal of the product. Stability failures are responsible for a third of product recalls, costing pharmaceutical companies millions. The risk of not conducting thorough stability testing, therefore, outweighs the cost of performing it.

    This course will provide you with an understanding of the science behind stability testing, a detailed examination of the ICH guidelines, and accurate assessments of the tools and techniques to carry out testing. Crucially you will gain a deeper understanding of the guidelines and how best to create stability protocols to maintain compliance.

Per the regulations, all Failures.

    Deviation or OOS results investigations regardless of its product impact should be appropriately documented, investigated, analyzed for root cause(s), with a justifiable retest plan and an effective corrective action plan. Understanding how to identify a true OOS from other types of Laboratory investigations (i.e. Invalid Assays, Known Lab Error, Atypical Events or a Lab Calibration out of Tolerance) as well as when to perform a retest based on the findings of the OOS investigation is critical to achieving compliance. It is also critical to know when and how to apply “averaging” versus an “outlier” to an original test and re-test data generated during an OOS result. This will allow a product manufacturer to achieve compliance relating to an OOS investigational process.

    The required quality for glass containers for pharmaceutical applications is described in global pharmacopeia, e.g., USP Chapter Containers – Glass or Ph. Eur. 3.2.1. Glass Containers for Pharmaceutical Use. Apart from pharmacopeia, the different glass types are also described in standards, such as ISO and ASTM.

    USP and Ph. Eur. have classified Type I glass as Borosilicate (BS) glass and Type III glass as soda-lime (SL) glass, each one with a certain limit for hydrolytic resistance. Typical BS glasses on the market are FIOLAX®, Corning®51-D / 51-V and NSV® 51. As it is an accepted custom to treat SL glass with ammonium sulfate on the inside to increase its chemical stability, this inner surface-treated SL glass was added in pharmacopeia and classified as Type II glass. Although there are different sub types of BS glass on the market, these are not differentiated in pharmacopeia. However, ASTM E 438 does distinguish between Type I Class A which is a BS glass with a lower thermal expansion, such as DURAN® or PYREX® glass and Type I Class B, which is a BS glass with a higher thermal expansion (alumino-borosilicate glass as per ASTM), known as FIOLAX®, Corning®51-D / 51-V or NSV® 51 glass.

    In 2017, data integrity issues were cited in 65% of all FDA warning letters. The main reason was incomplete data. In the pharmaceutical and biotechnology industries, this can be prevented by ensuring the trustworthiness and reliability of electronic records, a process that is also known as compliance with data integrity. The highest risks, when not working in a compliant manner, lie in import bans, product recalls, or even the closing of production plants. The FDA defines the criteria under which electronic records and electronic signatures are considered trustworthy, reliable, and equivalent to paper records in Title 21 of the Code of Federal Regulations (21 CFR) Part 11.

    In the biopharma industry, “human error” is often selected to describe a deviation for which the immediate apparent cause was the behavior, which could be through action or inaction, of the person(s) performing a task or process. Too often, “retraining” is selected as the preventive action that, hopefully, will prevent that person or persons from repeating the deviation. As anyone with significant experience working in the GMP domain knows, repetition of training may be effective for straightforward and simple work, but not for complex tasks or for activities that require the application of self-awareness, critical thinking, and real-time judgment, all of which are critical in situations that are not nominal to the process.

    One major potential point of friction on the approval journey is the need to specify and verify a compatible packaging combination for your drug product. Container closure integrity (CCI) is a critical aspect of drug development, and one that demands attention and investment early in the process to avoid complications and possible harm further down the line. This point is underlined by FDA data, which reveals that around a third (34%) of injectable product recalls in recent years can be linked to particulates or a lack of sterility attributable to the container closure combination.

    Abstract: Control and prevention of unwanted aggregation for therapeutic proteins is a ubiquitous hurdle during biopharmaceutical product manufacture, storage, shipping, and administration. Methods to predict the relative or absolute rates of aggregation are therefore of great practical interest in biopharmaceutical research and development. Aggregation is often well-described as a multi-stage process involving unfolding or misfolding of free monomers, along with one or more assembly steps to form soluble or insoluble oligomers or higher-molecular-weight species. This report reviews the current state of the art in experimental and practical theoretical approaches that attempt to predict in vitro protein aggregation rates or propensities relevant to pharmaceutical proteins. Most available approaches fall within four primary categories. The principles and assumptions underlying each category are reviewed, along with advantages and limitations in each case. The importance of appropriate experimental techniques and models to probe and quantify the thermodynamics and/or dynamics of multiple steps or stages within the overall aggregation process is stressed. The primary focus is on aggregation in solution, relevant to parenteral dosage forms. Additional challenges are briefly reviewed.

    Abstract: Combination products are therapeutic and diagnostic products that include two or more of the following: drug, biologic, and device. These products are needed for enhanced clinical outcomes and have more than one Mode of Action (MOA). Therefore, they require a more complex regulatory pathway and compliance with a minimum of two (2) sets of regulatory standards. In 2013, the 21 Code of Federal Regulations (CFR) Part 4 was published to clarify the applicable GMP regulations when drugs, devices, or biological products are included. The FDA (U.S. Food and Drug Administration) released additional guidance in 2017 to streamline the regulatory framework and provide transparency about demonstrating GMP compliance when multiple regulatory standards overlap. This paper summarizes the Current Good Manufacturing Practice (CGMP) requirements for drug-device combination products (Biologic combinations are not discussed in this paper). Emphasis is placed on considerations for structuring a compliant drug-device stability program, including the use of bracketing and matrixing the test schedule to support the establishment of the product expiry date and how legacy products can be evaluated to meet current standards.

    Abstract Repeatable and proper Container Closure Integrity Testing of primary packaging’s is essential to ensure quality and effectiveness of pharmaceutical products. Blue dye test and microbial ingress are mainly used for decades. Recently, guidelines provided by regulatory organizations like USP or Annex 1 request statistical analysis and push for use of deterministic and non-destructive methods.

    The following presents the results of a unique comparative study conducted on more than 500 glass vials that are prepared with leak artifacts (microtubes and glass micropipettes), which refers to Kirsch and Burrel’s studies. Each sample has been tested with different technologies: Helium Leak test, Optical Emission Spectroscopy, Mass Extraction and Blue Dye test. Depending on the needs (R&D, Production, Quality) the results can help the reader to find a suitable deterministic test method to replace the blue dye test and follow the latest guidelines.

    Introduction: The recently published general chapter USP states that water activity determination can be used to assess the level of protection provided by primary packaging for an oral solid dosage (OSD) product over its entire shelf life. Primary packaging must maintain a low relative humidity for as long as necessary to ensure the pharmaceutical product maintains its key quality attributes including potency, purity, dissolution rate, tablet hardness, and capsule swelling, up to its expiration date. During the development phase, data must be acquired to determine if an existing package can provide adequate protection, or if new technologies are required for new formulations. For commercial products, a replacement package must be assessed to determine if it has equivalent, inferior, or superior performance. Water activity (aw) measurements provide unique information, and therefore expand and complement the data collected from USP Auxiliary Packing Components and USP Containers - Performance Testing.

    Conclusion: Conventional ULT freezers are used for freezing and storage of biopharmaceutical bulk DS, but they are not always the optimal solution. ULT freezers are designed for storing frozen material and have limited capacity for freezing liquid DS.

    For freezing bulk DS, forced air convection freezers that are designed for the application provide much faster freezing rates, much more consistent freezing rates, and greater mechanical reliability.

    For storage of bulk DS, there are now three options available – conventional ULT freezers, large custom freezers, and a newer option of midsize ULC freezers. There are pros and cons to each option, and one tool to find the optimal solution is an economic evaluation. The results of an example evaluation show the optimum solution varies with the amount of freezer capacity required. For a small freezer capacity requirement (around five ULT freezers or fewer), ULT freezers provide the lowest overall cost. For very large applications where more than 100 ULT freezers would be required, the large custom freezers are optimal. And when freezer capacity of between five and 100 ULT freezers is required, the ULC freezer option gives the lowest overall cost. Key Words: Design, Strategies, Blast

    Introduction: Toward the end of 2022, the FDA issued guidance on the validation of biological assays, titled M10 Bioanalytical Method Validation and Study Sample Analysis.1 The guidance was originally issued in draft form in 2019; a little over three years was required to develop the final guidance document, and it was approved by ICH in May 2022. Hence, the FDA adoption completes international acceptance of a unified approach to biological assays. The objective of issuing the document was to address some concerns with regulatory submissions, and the document provides a set of recommendations for method validation for bioanalytical assays for nonclinical and clinical studies. As well as full validation, the guidance extends to partial validation where modifications are undertaken for previously validated assays. There is an additional intention centered on reducing the numbers of animals used in drug research and development.

    This article considers the core objectives of the guidance and how it applies to both GMP and GLP activities.

    One of the reported methods to estimate the probability of passing the USP dissolution test uses Mathematica software for calculation. The goal of this article is to calculate the probability of passing the USP dissolution test from that method using Microsoft Excel.

    Dissolution testing is performed to provide in vitro drug release information and to accurately predict the in vivo drug release. Dissolution tests are performed at different stages of the drug manufacturing process to ensure that the drug product meets the standards as specified in the United States Pharmacopoeia (USP). USP provides requirements for sampling, testing, and acceptance criteria for tests like content uniformity and dissolution.1,2 A manufacturing process is said to be in regulatory compliance only if it meets the acceptance criteria for all the tests specified in USP. To ensure there is a high probability of passing these tests, sponsors establish in-house specification limits to ensure there is a high probability of meeting these acceptance criteria. Different methods are reported in the literature to calculate the probability of passing the dissolution test.

    Introductory Paragraph: Revision of the ICH Stability Guideline Series Q1A-F and Q5C is recommended to a) streamline the series by combining the various guidelines into a single guideline focused on core stability principles; b) promote harmonised interpretation by addressing potential gaps and areas of ambiguity; c) address additional technical issues, including relevant stability strategies and innovative tools that strengthen the application of risk management; and d) consider inclusion of new topics, such as stability considerations for advanced therapies. The informal working group proposes to establish these updates through the Revision procedure. The envisioned result is a combined guideline, ICH Q1, with integrated annexes and/or appendices that address specific topics beyond the core principles on stability recommendations and to address product type1 specific recommendations, as required. It is also recommended to update and supplement current training material.

    Abstract: This article describes the use of temperature mapping as a process to qualify storage areas to maintain temperature for the storage of drugs, which is an effective strategy to identify risks as part of a quality management system.

    The authors point out that maintaining temperature during storage is an important aspect to make sure that the safety, efficacy, and expiry of drugs are kept. This, of course, includes avoiding temperature excursions during storage. To evaluate if storage areas can adequately maintain the appropriate temperature, temperature mapping studies are necessary.

    Conclusion: As manufacturers develop more advanced therapeutics, especially cell and gene therapies, solutions that support reliable cold chains will become central. Biopharmaceuticals culminate in complex design decisions requiring substantial research, resources, and time investment.

    Oftentimes, manufacturers will misguidedly look to improve end-user training and secondary packaging before first evaluating the most durable primary solutions to prevent product loss. Many recognize the critical aspect and value, both in cost and to patients, of container integrity. The key takeaway for manufacturers is that by choosing the most durable and innovative primary packaging, they can eliminate potential issues that might occur through subsequent phases of supply chain transportation.
