Abstract
Therapeutic monoclonal antibody (mAb) products for intravenous (IV) administration generally require aseptic compounding with a commercially available diluent. When the administration site is located away from the preparation site, the prepared dosing solution may need to be transported in a vehicle. The impact of vehicle transportation on the product quality of mAbs needs to be evaluated to define safe handling and transportation conditions for dosing solutions. The design and execution of actual vehicle transportation studies require considerable resources and time. In this study, we systematically developed three different laboratory equipment-based methods that simulate vehicle transportation stresses: orbital shaker (OS), reciprocating shaker (RS), and vibration test system (VTS)-based simulation methods. We assessed their feasibility by comparing the impact on product quality caused by each simulated method with that caused by actual vehicle transportation. Without residual polysorbate 80 (PS80) in the mAb dosing solution, transportation via a cargo van led to a considerable increase in the subvisible particle counts and did not meet the compendial specifications for the light obscuration method. However, the presence of as low as 0.0004%w/v (4 ppm) PS80 in the dosing solution stabilized the mAb against vehicle transportation stresses and met the compendial specifications. Vehicle transportation of an IV bag with headspace resulted in negligible micro air bubbles and foaming in both PS80-free and PS80-containing mAb dosing solutions. These phenomena were found to be comparable to the VTS-based simulated method. However, the OS- and RS-based simulated methods formed significantly more micro air bubbles and foaming in an IV bag with headspace than either actual vehicle transportation or the VTS-based simulated method. Despite the higher interfacial stress (micro air bubbles and foaming) in the dosing solution created by the OS- and RS-based simulated methods, 0.0004%w/v (4 ppm) PS80 in the dosing solution was found to be sufficient to stabilize the mAb. The study shows that under appropriate simulated conditions, the OS-, RS-, and VTS-based simulated methods can be used as practical and meaningful models to assess the impact and risk of vehicle transportation on the quality of mAb dosing solutions.

J Pharm Sci 2024; 113:990-998. [PMID: 37813303 DOI: 10.1016/j.xphs.2023.10.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 10/04/2023] [Accepted: 10/04/2023] [Indexed: 10/11/2023]
Abstract
Residual volumes of infusion solutions vary greatly due to container and dimensional variances. Manufacturers use overfill to compensate, but the exact amounts vary significantly. This variability in overfill - when carrier solutions are used to dilute other parenteral preparations - may lead to variable concentrations and dosing, hence, potential risk for patients. We analyzed the overfill and residual volume of 22 pre-filled infusion containers and evaluated the impact on the (simulated) dosing accuracy of a therapeutic drug product for different handling scenarios. In addition, compendial properties of the diluents (i.e. sub-visible particles, pH, color and opalescence) were assessed. The overfill and residual volume between different containers for the same diluent varied. As container size increased, the relative volume of overfill decreased while the residual volume remained constant. The design and material of the containers (e.g. port systems) defined the residual volume. Different handling scenarios led to differences in dosing accuracy. As a result, no universal approach applicable for all containers can be defined. To ensure the right dose, it is recommended to pre-select the preferred diluent, evaluate fill volumes of carrier solutions, and assess in-use compatibility of the product solution with its diluent in terms of concentration and volume.

Abstract
The emergence of highly potent therapeutics with low expected clinical doses creates a challenge for analytical characterization of simulated drug product in-use samples. The low expected protein concentration (often µg/mL) and highly charged and sub-optimal sample matrices like 0.9% saline or 5% dextrose make ensuring dose solution stability and characterizing product quality changes difficult. Health authority expectations require analysis of low concentration in-use samples to be completed with suitable assays to ensure little to no changes are occurring during drug product dose preparation and administration, thus ensuring patient safety. However, characterization of these samples for protein concentration, size variants, charge variants and potency often necessitates additional analytical method development to improve sensitivity and compatibility with in-use samples. Here we report the development and qualification of reliable in-use methods to characterize simulated in-use samples to assist during drug product development.

Eur J Pharm Biopharm 2024; 194:148-158.

Abstract
We herein report that filgrastim product Neupogen® and the filgrastim formulation buffer induced aggregate formation when mixed in vitro with human plasma, and formation of large membranous erythrocyte aggregates when mixed with human blood, similar to the aggregation induced by pegfilgrastim and by pegfilgrastim buffer [T. Arvinte, E. Poirier, N. Ersayin, G. Darpin, A. Cudd, J. Dowd, S. Brokx, Aggregation of human plasma and of human blood induced in vitro by pegfilgrastim originator formulation buffer and pegfilgrastim products, Eur. J. Pharmaceut. Biopharmaceut. (2023), doi: 10.1016/j.ejpb.2023.10.019]. The data identify the filgrastim buffer (which is practically the same in filgrastim and pegfilgrastim products) as the main driver of human plasma and blood aggregation. Kinetic experiments showed differences in the extent of plasma aggregation induced by a filgrastim product manufactured in EU and one manufactured in USA. Human donor variability in the plasma aggregation induced by filgrastim was observed. To study the effect of PEGylation of the filgrastim protein on plasma aggregation we compared filgrastim (Neupogen®) with pegfilgrastim (Neulasta®) solutions at the same protein concentration. These data show that PEGylation has a beneficial effect in inhibiting to an extent plasma aggregation. Interestingly, 20 kDa polyethylene glycol in the filgrastim buffer induced more plasma aggregation compared to the buffer, similar to the aggregation induced by pegfilgrastim. For intravenous infusion filgrastim solutions (300 µg/ml, vials only) may be diluted in 5 % dextrose from a concentration of 300 µg/ml to 5 µg/ml. Aggregation of human plasma was also induced by filgrastim solutions diluted in 5 % dextrose to 50 µg/ml, 15 µg/ml and 5 µg/ml filgrastim, as well as by the filgrastim buffer similarly diluted in 5 % dextrose (1:6, 1:20 and 1:60 dilution). These data show that filgrastim solutions used for intravenous administration in patients induce human plasma aggregation in vitro. Such aggregation phenomena may be related to known infusion side effects of filgrastim therapy.

Abstract
Monoclonal antibody (mAb) products for intravenous (IV) administration generally require aseptic compounding with a commercial diluent within a pharmacy. The prepared dosing solution in the IV bag may be transported to the dosing location via manual, vehicular, pneumatic tube system (PTS), or a combination of these methods. In this study, the type and level of physical stresses associated with these three methods and their product quality impact for relatively sensitive and stable mAbs were assessed. Vibration was found to be the main stress associated with manual and vehicle transportation methods, although this was at a relatively low level (<1 GRMS/Root-Mean-Square Acceleration). Shock and drop events, at relatively low levels, were also observed with these methods. PTS transportation showed substantially more intense shock, vibration, and drop stresses and the measured levels were up to 91 G/force of acceleration or deceleration, 3.7 GRMS and 39 G, respectively. Using a foam padding insert for PTS transportation reduced the shock level considerably (91 G to 59 G). Transportation of mAb dosing solutions in IV bags via different methods including PTS transportation variables caused a small increase in the subvisible particle counts and there was no change in submicrometer particle distribution. No visible particles and no significant change to soluble aggregate levels were observed after transportation. Strategies such as removal of IV bag headspace prior to transport and in-line filtration poststress reduced the subvisible particles counts. All tested transportation conditions showed negligible impact on other product quality attributes tested. Removal of IV bag headspace prior to PTS transport prevented formation of micro air bubbles and foaming compared to the unaltered IV bag. This study shows examples where manual, vehicle, and PTS transport methods did not significantly impact product quality, and provides evidence that mAb products that are appropriately stabilized in the dosing solution (e.g., with a surfactant) can be transported via a PTS.

Evaluation of the In-Use Stability of Monoclonal Antibody IV Admixtures Prepared from Drug Products Containing Polysorbate 20 Degraded by Host-Cell Lipases. J Pharm Sci 2023; 112:3045-3055. [PMID: 37643700 DOI: 10.1016/j.xphs.2023.08.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/10/2023] [Revised: 08/23/2023] [Accepted: 08/23/2023] [Indexed: 08/31/2023]
Abstract
Host-cell lipases can be present in monoclonal antibody drug products and can degrade polysorbates present in the formulations as stabilizers. We hypothesized that the in-use stability of the IV admixture prepared from such a drug product might be impacted by decreasing levels of polysorbate 20. Host-cell lipase activity has, in fact, been observed during development of one of our therapeutic monoclonal antibody drug products. Throughout the course of the product shelf life, polysorbate 20 levels decreased but no other quality attributes of the drug product were impacted. An experimental approach was developed to simulate how the prepared IV admixture in-use stability is affected as polysorbate 20 concentration in the drug product decreased over the shelf life, and from that a minimum level of polysorbate 20 required in the drug product was determined to estimate the in-use stability of the IV admixture as the polysorbate 20 in the drug product degrades. The results indicate that although the observed degradation of polysorbate 20 does not affect quality attributes of this drug product, in-use stability of the IV admixture as a function of polysorbate degradation can be impacted and should be assessed to ensure sufficient quality.

Abstract
Active ingredients of biopharmaceuticals consist of a wide array of biomolecular structures, including those of enzymes, monoclonal antibodies, nucleic acids, and recombinant proteins. Recently, these molecules have dominated the pharmaceutical industry owing to their safety and efficacy. However, their manufacturing is hindered by high cost, inadequate batch-to-batch equivalence, inherent instability, and other quality issues. This article is an up-to-date review of the challenges encountered during different stages of biopharmaceutical production and mitigation of problems arising during their development, formulation, manufacturing, and administration. It is a broad overview discussion of stability issues encountered during product life cycle i.e., upstream processing (aggregation, solubility, host cell proteins, color change), downstream bioprocessing (aggregation, fragmentation), formulation, manufacturing, and delivery to patients.

Abstract
![]()
Monoclonal antibodies
are the fastest growing class of therapeutics.
However, aggregation limits their shelf life and can lead to adverse
immune responses. Assessment and optimization of the long-term antibody
stability are therefore key challenges in the biologic drug development.
Here, we present a platform based on the analysis of temperature-dependent
aggregation data that can dramatically shorten the assessment of the
long-term aggregation stability and thus accelerate the optimization
of antibody formulations. For a set of antibodies used in the therapeutic
areas from oncology to rheumatology and osteoporosis, we obtain an
accurate prediction of aggregate fractions for up to three years using
the data obtained on a much shorter time scale. Significantly, the
strategy combining kinetic and thermodynamic analysis not only contributes
to a better understanding of the molecular mechanisms of antibody
aggregation but has already proven to be very effective in the development
and production of biological therapeutics.

Abstract
Monoclonal antibodies (mAbs) and excipients can degrade owing to different stress factors they encounter during their life cycle or after administration in human body. This can result in the formation of aggregates and particulates. As particles can evoke an immune response in patients, it becomes increasingly important to monitor their fate after administration. In this study, we used a protein-free serum model to assess the fate of mAb and polysorbate (PS) particles under physiologic conditions. Commonly encountered stress conditions such as pH, temperature, extrusion, and shaking were chosen to generate mAb particles. Alkaline hydrolysis was used to generate PS particles. The fate of aggregates and particles was evaluated in serum and histidine buffer. We observed that depending on the nature of stress and the environment particles are subjected to, the fate of particles can differ substantially. The mAb aggregates generated by pH stress, showed reduction in HMWS from 26% to 6% over 14days in human serum filtrate. PS particles dissolved at 37°C but remained unaltered in Histidine at 5°C. Our results reinforce the need to track the fate of particles generated during drug product development upon exposure to physiologic conditions.

Abstract
The formation of particulates in post-manufacture biopharmaceuticals continues to be a major concern in medical treatment. This study was designed to evaluate the content of micro-sized particles using flow imaging of antibodies in intravenous infusion bags. Intravenous immunoglobulin (IVIG) and Avastin® were selected as model drugs and plastic syringes with and without silicone oil (SO) were used to transfer the drugs into the bags (0.9% saline or 5% dextrose). Antibodies exposed to SO had significantly increased levels of microparticles in both diluents, suggesting SO accelerates particle formation, especially at a higher antibody concentration. Even before the drop stress, their count exceeded the USP guideline. Dropping the bags in the presence of SO produced larger microparticles. Meanwhile, air bubbles were retained longer in saline suggesting more protein film formation on its air-water interface. Overall, both drugs were conformationally stable and produced less particles in dextrose than in saline.

Abstract
Therapeutic proteins are administered by injection or infusion. After administration, the physiologic environment in the desired body compartment - fluid or tissue - can impact protein stability and lead to changes in the safety and/or efficacy profile. For example, protein aggregation and fragmentation are critical quality attributes of the drug product and can occur after administration to patients. In this context, the in vivo stability of therapeutic proteins has gained increasing attention. However, in vivo protein aggregation and fragmentation are difficult to assess and have been rarely investigated. This mini-review summarizes analytical approaches to assess the stability of therapeutic proteins using simulated physiologic conditions. Furthermore, we discuss factors potentially causing in vivo protein aggregation, precipitation, and fragmentation in complex biological fluids. Different analytical approaches are evaluated with respect to their applicability and possible shortcomings when it comes to these degradation events in biological fluids. Tracking protein stability in biological fluids typically requires purifying or labeling the protein of interest to circumvent matrix interference of biological fluids. Improved analytical methods are strongly needed to gain knowledge on in vivo protein aggregation and fragmentation. In vitro models can support the selection of lead candidates and accelerate the pre-clinical development of therapeutic proteins.

Constant infusion case of one compartment pharmacokinetic model with simultaneous first-order and Michaelis-Menten elimination: analytical solution and drug exposure formula. J Pharmacokinet Pharmacodyn 2021; 48:495-508. [PMID: 33629256 DOI: 10.1007/s10928-021-09740-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2020] [Accepted: 01/20/2021] [Indexed: 10/22/2022]
Abstract
The main objective of this article is to propose the closed-form solution of one-compartment pharmacokinetic model with simultaneous first-order and Michaelis-Menten elimination for the case of constant infusion. For the case of bolus administration, we have previously established a closed-form solution of the model through introducing a transcendent X function. In the same vein, we found here a closed-form solution of constant infusion could be realized through introducing another transcendent Y function. For the general case of constant infusion of limited duration, the closed-form solution is then fully expressed using both X and Y functions. As direct results, several important pharmacokinetic surrogates, such as peak concentration [Formula: see text] and total drug exposure AUC[Formula: see text], are found the closed-form expressions and ready to be analyzed. The new pharmacokinetic knowledge we have gained on these parameters, which largely exhibits in a nonlinear feature, is in clear contrast to that of the linear case. Finally, with a pharmacokinetic model adapted from that formerly reported on phenytoin, we numerically analyzed and illustrated the roles of different model parameters and discussed their influence on drug exposure. To conclude, the present findings elucidate the intrinsic quantitative structural properties of such pharmacokinetic model and provide a new avenue for future modelling and rational drug designs.

Abstract
The stability of therapeutic proteins can be impacted in vivo after administration, which may affect patient safety or treatment efficacy, or both. Stability testing of therapeutic proteins using models representing physiologic conditions may guide preclinical development strategy; however, to date only a few studies assessing the physical stability are available in the public domain. In this manuscript, the stability of seven fluorescently labeled monoclonal antibodies (mAbs) was evaluated in human serum and phosphate-buffered saline, two models often discussed to be representative of the situation in humans after intravenous administration. Subvisible particles were analyzed using light obscuration, flow imaging, and imaging flow cytometry. All methods showed that serum itself formed particles under in vitro conditions. Imaging flow cytometry demonstrated that mean particle size and counts of mAbs increased substantially in serum over five days; however, particle formation in phosphate-buffered saline was comparably low. Stability differences were observed across the mAbs evaluated, and imaging flow cytometry data indicated that fluorescently labeled mAbs primarily interacted with serum components. The results indicate that serum may be more suitable as in vitro model to simulate physiologic intravenous conditions in patients closely and evaluate the in vivo stability of therapeutic proteins. Fluorescence labeling and detection methods may be applied to differentiate particles containing therapeutic protein from high amounts of serum particles that form over time.

Abstract
In recent years, there has been increased scrutiny on the presence and formation of product-related particles in biopharmaceutical formulations. These types of particles, originating from the degradation of the active pharmaceutical ingredient or the excipients, can be challenging to identify and characterize due to their fragility. Additionally, the mechanisms of their formation as well as the impact of their presence on drug product safety can be complicated to elucidate. In this work, a case study is presented in which multiple batches of one formulated monoclonal antibody (mAb-A) were analyzed at different batch ages to better understand the formation of visible particles resulting from degradation of the surfactant polysorbate 20. The particle identity was determined by Raman spectroscopy as free fatty acid (FFA) and the particle composition over time was monitored by mass spectrometry. Further experimental work includes the counts and morphologies of subvisible particles by flow imaging microscopy. Finally, we evaluated the consequences of saline and human plasma exposure to the visible particles to better understand their fate upon dilution and/or administration which is routinely performed in the clinical setting. The experiments performed in this work can be used to support risk assessments of visible product-related particles.
