Capping completes the closure of parenteral drug products in the final packaging container and is critical in maintaining an integral seal to ensure product quality. Residual seal force (RSF) is considered the sole quantifiable attribute for measuring seal “goodness” and potentially enables non-subjective, consistent setting of cappers across manufacturing sites. However, the consistency and reliability of RSF measurement and data have been scarcely reported, and the relationship between RSF and container closure integrity (CCI) remains poorly understood...

Delamination, which is the formation of flakes in drug products due to specific and localized corrosion of glass vials, is a rare but very serious problems, and the FDA (U.S. Food and Drug Administration) put a warning to the pharma industry in 2011. Technical Committee TC12 of the International Commission on Glass (ICG) was created in 2012, with the aim to study the problems related to pharma packaging. The first task of TC12 was to address the problem of predicting the propensity of glass vials to delamination, leaving the study of the mechanism(s) of flake formation as a possible future activity...

The terminal sterilization of drugs and devices is the most appropriate means of assuring patient safety in terms of prevention of infection. Adoption of terminal sterilization processes requires a supporting and thorough program for control and monitoring of bioburden; especially if a parametric release program of sterilization is desired. Such a control program must necessarily assess and evaluate the resistance of associated bioburden (primarily spores) which may resist inactivation and challenge the sterilization cycle...

This study compared an ATP-based bioluminescence rapid microbial method (RMM) with a conventional sterility method for biologic sample testing. The RMM is based on a comparison of ATP levels in inoculated and uninoculated microbiological growth medium samples following growth enrichment incubation. The biologics samples qualified in this study were recombinant monoclonal antibodies and hybridoma cell culture supernatants. Initially, the lot-to-lot variation in background ATP of these samples posed significant challenges...

Pharmacopoeias recognize particulate matter as a common phenomenon. The current regulatory requirements relating to particulate matter in parenterals state that solutions for injections or infusions are clear and “practically” (or “essentially”) free from (“readily detectable”) particles when examined under defined conditions of illumination. Pharmaceutical companies are required to know their processes and have them under control. In order to control and reduce the potential influx of particulate matter, Novartis Technical Operations in Unterach developed a particle life cycle program that involved an establishment of a dedicated particle laboratory operating under clean room conditions...

The sensitivity of drugs to one or more elements of the primary packaging is a serious concern for the pharmaceutical industry. Biologics in particular are highly sensitive, leading to a higher risk of incompatibility and stability test failures as worst case scenario. This potential incompatibility - and the consequent formulation instability due to the interactions between the drug and the primary container surface - may have multiple causes: the intrinsic nature of the container surface, leachables coming from the materials used, substances coming from the production process, silicone oil droplets or other particles...

Monoclonal antibodies (mAbs) are exposed to light during drug product (DP) manufacturing and the acceptable levels of light exposure needs to be determined based on the impact on product quality. In this study, a mild and more representative light model consisting of ambient light instead of stress light as prescribed by ICH Q1B was used to evaluate the impact of light exposure on mAb DP quality. The immediate effect of ambient light exposure on protein drug product quality was determined to be dependent on the amount of light exposure rather than light intensity (up to 5000 lux)...

Frozen-state storage and cold-chain transport are key operations in the development and commercialization of biopharmaceuticals. Nowadays, a few marketed drug products are stored (and/or) shipped under frozen conditions to ensure sufficient stability, particularly for live viral vaccines. When these products are stored in glass vials with stoppers, the elastomer of the stopper needs to be flexible enough to seal the vial at the target's lowest temperature to ensure container closure integrity and hence both sterility and safety of the drug product...

Particles in drug products are not good and are therefore regulated. These particles can come from the very beginning of the manufacturing process, from the raw materials. To prevent particles, it is important to understand what they are and where they come from so the raw material quality, processing, and shipping can be improved. Thus, it is important to correctly identify particles seen in raw materials. Raw materials need to be of a certain quality with respect to physical and chemical composition, and need to have no contaminants in the form of particles which could contaminate the product or indicate the raw materials are not pure enough to make a good quality product...

Monoclonality of mammalian cell lines used for production of biologics is a regulatory expectation and one of the attributes assessed as part of a larger process to ensure consistent quality of the biologic. Historically, monoclonality has been demonstrated through statistics generated from limiting dilution cloning or through verified flow cytometry methods. A variety of new technologies are now on the market with the potential to offer more efficient and robust approaches to generating and documenting a clonal cell line...

Product knowledge grows and evolves during the life of a product. In order to maintain a state of control and deliver product with consistent quality throughout its commercial life, continuous improvement and product lifecycle management become essential. The practical link between product and process knowledge, risk-based control strategies, and continual improvement and innovation can be made stronger through evidence-based risk reduction. Regulatory relief and flexibility in post approval change management and overall product lifecycle management will only be possible with effective application of science and risk-based concepts and demonstrated effectiveness of the PQS in assuring a state of control...

There has been a growing interest in recent years in the assessment of suitable vial/stopper combinations for storage and shipment of frozen drug products. Considering that the glass transition temperature (Tg) of butyl rubber stoppers used in Container Closure Systems (CCS) is between -55°C to -65°C, a storage or shipment temperature of a frozen product below the Tg of the rubber stopper, may require special attention, since below the Tg the rubber becomes more plastic-like and loses its elastic (sealing) characteristics...

Recently, the use of filters has come into light for sanitizing water plants. This study investigated the role of heat-tolerant ultrafilters (UFs) for the remediation of reverse osmosis (RO) plants using periodic thermal disinfection. Two completely identical RO plants (RO plants A & B) were installed in 2006 for surgical hand antisepsis in the operating theater. RO water was stored in the 300-liter storage tank and re-circulated in the 190 meter-long loop delivering water to 12 faucets in each RO plant...

A monoclonal antibody drug product (DP) manufacturing process was transferred to a different production site, where aseptic filling took place within an isolator that was sanitized using vapor phase hydrogen peroxide (VPHP). A quality-by-design approach was applied for study design to understand the impact of VPHP uptake in the isolator on DP quality. A combination of small-scale and manufacturing-scale studies was performed to evaluate the sensitivity of the monoclonal antibody to hydrogen peroxide (H2O2) as well as VPHP uptake mechanisms during the filling process...
