Abstract
The two anti-epidermal growth factor receptor monoclonal antibodies (mAbs) cetuximab and panitumumab are the pillars for the treatment of EGFR-positive, KRAS wild-type metastatic colorectal cancers. However, stability data of these mAbs are generally missing or incomplete. Here, we report for the first time an orthogonal analysis of the stability of cetuximab (Erbitux®) and panitumumab (Vectibix®), either undiluted vial leftovers or saline dilutions in polyolefin/polyamide infusion bags. All samples were stored at 2-8 °C protected from light, according to their summary of product characteristics (SmPCs). Alternatively, opened vials and preparations were maintained at 25 °C for 15 h, and then stored again at 2-8 °C protected from light to mimic a temporary interruption of the cold chain. Vial leftovers proved stable up to 180 days when stored according to their SmPCs, while compounded preparations in infusion bags maintained their physiochemical, biological and microbiological stability up to 30 days. Additionally, no changes were detected up to 30 days for the same samples undergoing a thermal excursion. Our results provide additional rationale to the SmPCs, crucial especially in the case of reassignment and pre-preparation of bags. This information will allow hospitals to achieve significant cost savings, and better organization of the entire therapeutic process.

[PMID: 37078110 PMCID: PMC10804814 DOI: 10.1177/10781552231170583] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Revised: 04/03/2023] [Accepted: 04/03/2023] [Indexed: 04/21/2023]
Abstract
INTRODUCTION This study aimed to determine the stability of cetuximab: (1) under "in-use" conditions after dilution to 1 mg/mL in 0.9% sodium chloride in polyolefin bags and (2) as an undiluted solution (5 mg/mL) repackaged in polypropylene bags or kept in the vial after opening. METHODS Ready-to-use 500 mg/100 mL vials of cetuximab solution were diluted to 1 mg/mL in 100 mL bags of 0.9% sodium chloride or repackaged as a 5 mg/mL solution into empty 100 mL bags. Bags and vials were stored at 4°C for 90 days and 25°C for 3 days. A syringe sample of 7 mL was taken from each bag for the initial determinations. The sampled bags were weighed to determine their initial weight and placed under the planned storage conditions. The physicochemical stability of cetuximab was estimated using validated methods. RESULTS No changes in turbidity, no protein loss, and no changes in cetuximab tertiary structure were observed after 30 days of storage or when subjected to a temperature excursion of 3 days at 25°C and when stored at 4°C for up to 90 days, regardless of the concentrations and batches. The colligative parameters did not change under any of the tested conditions. No evidence of microbial growth was found in bags after 90 days of storage at 4°C. CONCLUSION These results support the extended in-use shelf-life of cetuximab vials and bags, which can be cost-effective for healthcare providers.

Abstract
OBJECTIVE In multiple myeloma patients, daratumumab is preferably injected subcutaneously. The summary of product characteristics of daratumumab subcutaneous injection solution specifies physicochemical stability for the prepared syringe for 24 hours at 2-8°C protected from light, and another 12 hours at room temperature (15-25°C) in ambient light conditions. The aim of this study was to determine the in-use stability of ready-to-administer daratumumab subcutaneous injection solution in different types of syringe and different conditions over a 28-day period. METHODS Daratumumab subcutaneous (DARZALEX 1800 mg) injection solution was withdrawn into disposable three-piece Luer-Lock syringes (20 mL, 50 mL), capped, and stored light protected at 2-8°C or at room temperature (22±2°C) over a maximum period of 28 days. Samples were taken immediately after preparation (day 0) and after 2, 7, 14, 21, and 28 days. Physicochemical stability was determined by ion-exchange high-performance liquid chromatography (IE-HPLC) and size-exclusion high-performance liquid chromatography (SE-HPLC) with ultraviolet detection, pH measurement and visual inspection for particles or colour changes. RESULTS In the IE-HPLC assay, peak areas and peak-to-peak area ratios remained unchanged over the whole study period, and showed no additional peaks of degraded daratumumab charge variants. In the SE-HPLC assay, neither a formation of aggregates nor of fragments was detected. Daratumumab monomer concentrations exceeded 95% of the initially measured concentrations over the entire test period. pH values remained constant. Test solutions remained clear, and no colour changes or visible particles were detected. All results were independent of storage conditions. CONCLUSION Daratumumab subcutaneous injection solution proved to be physicochemically stable in capped three-piece plastic syringes for at least 28 days when stored light protected at 2-8°C or at room temperature (22±2°C). For microbiological reasons aseptic preparation and refrigerated storage are recommended. In-use stability of ready-to-administer daratumumab subcutaneous syringes prepared under appropriate aseptic conditions is given for 28 days.

Abstract
Durvalumab is a monoclonal antibody approved for the treatment of lung, urothelial and biliary tract cancers. Durvalumab is supplied in vials as a solution containing no preservatives. Monographs recommend single use of durvalumab vials, and that any leftovers be discarded within 24 h. Thus, significant portions of unused product from opened vials are wasted on a daily basis, generating considerable financial losses. The objective of the present study was to assess the physicochemical and microbiological stability of durvalumab vials kept at 4 °C or room temperature, at 7 and 14 days after opening. Following pH and osmolality measurements, turbidity and submicronic aggregation of durvalumab solution were evaluated by spectrophotometry and dynamic light scattering, respectively. Moreover, steric exclusion high performance liquid chromatography (SE-HPLC), ion exchange HPLC (IEX-HPLC) and peptide mapping HPLC were used to respectively assess aggregation/fragmentation, charge distribution and primary structure of durvalumab. Microbiological stability of durvalumab was evaluated by incubation of vial leftovers on blood agar. All experiments showed physicochemical and microbiological stability of durvalumab vial leftovers for at least 14 days when aseptically handled and kept at either 4 °C or at room temperature. These results suggest the possible extension of utilization of durvalumab vial leftovers well beyond 24 h.

Abstract
Abstract
Objectives
Bevacizumab was first marketed in 2005. Since then, its stability has been extensively studied. The arrival of numerous biosimilars on the market has called into question these stabilities and organisation within reconstitution units. To study the stability of the Bevacizumab biosimilar Alymsys® marketed by Zentiva laboratory in ready-to-use vials at a concentration of 25 mg/mL and following dilution to obtain final concentrations of 1.4 and 16.5 mg/mL and storage in polyolefin IV bags at 4 °C. In parallel, the impact of a storage temperature excursion at 25 °C for three days and storage of the vial before opening at room temperature (25 ± 2 °C) and after opening at 4 °C was studied.
Methods
The vials were supplied by Zentiva laboratory. The vials (three batches) were diluted to the final concentrations of 1.4 or 16.5 mg/mL in 100 mL IV bags of NaCl. The IV bags and vials were stored at 4 °C and at room temperature throughout the duration of the study. The physico-chemical stability was tested using the following methods: turbidimetry, UV spectrometry and fluorescence, dynamic light scattering, ion exchange and steric exclusion chromatography, pH, osmolality and density.
Results
Out of all the parameters studied, for the two concentrations and standard storage conditions (90 days at +4 °C) or after a three-day temperature excursion at +25 °C, no modification was detected for the three batches tested with respect to physical and chemical stability. Hence, no signs of physical instability were observed, with, in particular, the absence of formation of submicron or micron sized aggregates and particles. The steric exclusion chromatography profiles did not demonstrate any oligomer formation or molecular structure rupture. Ion exchange chromatography did not demonstrate any significant modification in the distribution of charge variants. Derivative UV and fluorescence spectral analysis did not demonstrate any modification. The thermal denaturation curves were identical, suggesting the absence of thermodynamic destabilisation. Identical results were observed for the vials stored for 60 days at 4 °C after opening. Finally, only ion exchange chromatography demonstrated a slight change after 45 days of storage at 25 °C for vials before opening.
Conclusions
After dilution in sterile conditions with 0.9% NaCl in polyolefin IV bags, at the usual concentrations of 1.4 and 16.5 mg/mL, the Bevacizumab biosimilar Alymsys® is stable for at least three months at 4 °C protected from light and after a three-day temperature excursion at +25 °C. The same conclusions can be reached for the 25 mg/mL vials stored for 60 days at +4 °C after opening. However, the stability of vials stored at 25 °C before opening is no longer guaranteed beyond 15 days.

Eur J Pharm Biopharm 2022; 176:54-74. [PMID: 35595030 DOI: 10.1016/j.ejpb.2022.05.005] [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: 03/02/2022] [Revised: 05/05/2022] [Accepted: 05/07/2022] [Indexed: 11/19/2022]
Abstract
The stability of the monoclonal antibody Ipilimumab, the active ingredient of Yervoy®, used for the treatment of different types of cancer, has been investigated. Shaking/temperature, light exposure and dilution, protein drug renowned stressors, were applied on a 30-45-day series of experiments to observe the physicochemical and biological behavior of the molecule. Ipilimumab demonstrated stability under shaking and heat up to 45 days, without any unfolding during the induced combined stressors. Under artificial sunlight, the mAb showed to be sensitive even under the minimum dose tested (720 kJ/m2) with formation of aggregates, particularly when diluted in glucose solution. The light-induced soluble aggregates were higher in the case of diluted samples irradiated with much higher light doses (10460 kJ/m2). The aggregation of Ipilimumab took place also by irradiating the non-diluted formulation, indicating that the excipients did not protect completely the drug from photodegradation. Amino acid oxidation and deamidation were found. Anyway, after irradiation with both light doses, soluble Ipilimumab maintained its typical β-sheets structure, and the tertiary structure was nearly maintained compared to the dark. As an additional stressor test, the effect of dilution on the formulation was monitored by using a saline solution (1 mg/mL Ipilimumab) applied during hospital infusion. After two days from dilution, the protein exhibited aggregation and chemical modifications including oxidation and deamidation. When stability conditions were compromised, the viability of human cell lines treated with the stressed formulation slight decreased suggesting low potential biological toxicity of the modified mAb. As this study has demonstrated the susceptibility of Ipilimumab to light, specific solutions, and excipients as well as the use of safe light in manufacturing, handling, and storage of this drug should be promoted. Moreover, the use of proper primary and secondary packaging should be indicated to avoid the detrimental effect of light on the mAb structure and efficacy. A detailed understanding of Ipilimumab physicochemical properties, integrity, and stability could assure the best storage and manipulation conditions for its safe and successful application in cancer therapy.

Abstract
Succinimide (Asu) is the intermediate for asparagine deamidation in therapeutic proteins, and it can be readily hydrolyzed to form aspartate and iso-aspartate residues. Moreover, Asu plays an important role in the protein degradation pathways, asparagine deamidation, and aspartic acid isomerization. Here, Asu modification with a high abundance in the framework region (FR) of golimumab was first reported, the effect of denaturing buffer pH on the Asu modification homeostasis was studied, and the results revealed that it was relatively stable over a pH range of 6.0–7.0 whereas a rapid decrease at pH 8.0. Then, the peptide-based multi-attribute method (MAM) analyses showed that the Asu formation was at Asn 43 in the FR of the heavy chain. Meanwhile, the efficacy [affinity, binding and bioactivity, complement-dependent cytotoxicity (CDC) activity, and antibody-dependent cell-mediated cytotoxicity (ADCC) activity] and stability of the Asu modification of golimumab were evaluated, and the current results demonstrated comparable efficacy and stability between the Asu low- and high-abundance groups. Our findings provide valuable insights into Asu modification and its effect on efficacy and stability, and this study also demonstrates that there is a need to develop a broad-spectrum, rapid, and accurate platform to identify and characterize new peaks in the development of therapeutic proteins, particularly for antibody drugs.

Abstract
BACKGROUND Intratumorous immunotherapy for cancer is currently thriving. The aim of such local strategy is to improve the therapeutic index of these treatments, for higher on-target/on-tumor activity and less on-target/off-tumor adverse events. Strategies allowing for slow release of anti-CTLA4 in the tumor microenvironment could improve their clinical efficacy.The purpose of the study was to develop a radiopaque delivery platform to improve the targeting and exposure of intratumorous anti-CTLA4 antibodies for cancer immunotherapy. METHODS Pickering emulsions of anti-CTLA4 antibodies were formulated with radiopaque ethiodized oil and poly-lactic-co-glycolic acid (PLGA) nanoparticles. We characterized the microscopic aspect and stability of such emulsions using Turbiscan. We monitored the release of anti-CTLA4 over time from these emulsions and evaluated their structure using mass spectrometry. We then tested the functionality of the released antibodies by preforming ex vivo competitive binding assays. Finally, we assessed the in vivo efficacy of intratumorous anti-CTLA4 Pickering emulsions. RESULTS Pickering emulsions of ethiodized oil and PLGA nanoparticles (PEEPs) resulted in a radiopaque water-in-oil emulsion with average internal phase droplet size of 42±5 µm at day 7. Confocal microscopy showed that anti-CTLA4 antibodies were effectively encapsulated by ethiodized oil with PLGA nanoparticles located at the interface between the aqueous and the oily phase. Turbiscan analysis showed that emulsions were stable with continuous and progressive release of anti-CTLA4 antibodies reaching 70% at 3 weeks. Structural and functional analysis of the released antibodies did not show significant differences with native anti-CTLA4 antibodies. Finally, intratumorous anti-CTLA4 PEEPs were able to eradicate tumors and cure mice in a syngeneic immunocompetent preclinical tumor model. CONCLUSION Pickering emulsions of ethiodized oil and PLGA is an innovative radiopaque delivery platform that does not alter the functionality of anti-CTLA4 immune checkpoint antibodies. Beyond local anti-CTLA4 applications, these emulsions might be used with other therapeutic molecules for optimal intratumorous or intra-arterial delivery of novel cancer immunotherapies.

Abstract
Background: MYL-1401O; trastuzumab-dkst (Ogivri™; Mylan Inc.) is a biosimilar to the trastuzumab reference product (Herceptin®; Genentech, USA). Assessment of physicochemical stability and biological activity for the non-reconstituted, reconstituted, and infused solution over an extended, clinically relevant duration is critical for ensuring optimal patient outcomes and health resource utilization.Methods: The physicochemical and biological stability of MYL-1401O was assessed in non-reconstituted vials stored at 25 °C ± 2 °C/60% ± 5% relative humidity (RH) for 6 months, reconstituted 21 mg/mL solution in vials stored at 2 °C to 8 °C for 10 days, and diluted in 0.9% saline-containing infusion bags at 0.3 mg/mL and 4.0 mg/mL stored for 77 days at 2 °C to 8 °C, plus an additional 2 days at 25 °C ± 2 °C/60% ± 5% RH.Results: At all storage conditions tested, MYL-1401O was physicochemically and biologically stable for extended duration and under various temperature and humidity conditions.Conclusions: MYL-1401O retained its physicochemical and biological stability under different storage conditions, which supports advanced preparation of MYL-1401O, better efficiency, less wastage, and cost-savings for better patient management.

Abstract
Monoclonal antibody (Mabs) containing medicinal products are widely used in clinical practice. Prior to parenteral administration, licensed Mab containing medicinal products are transferred to the ready-to-administer (RTA) forms. Reconstitution and/or preparation should follow the guidelines for Good Reconstitution/Good Preparation Practice. Preparation in the pharmacy must take place within the framework of a suitable quality management system. The responsible pharmacist must apply a risk assessment on the process to ensure the appropriate quality of the RTA preparation, especially because the extent of quality testing is limited by batch size (often one single unit) and time restraints. In these cases, appropriate quality is to be assured by means of qualification activities, environmental monitoring, process validation with growth medium and in-process controls. Correct labelling of the Mab containing RTA preparations includes a suitable storage advice and a defined shelf life. Physicochemical stability of a given Mab preparation can be assessed based on a specific stability study (supplied by the manufacturer in the SmPC or scientific journals, study published by an expert in a peer-reviewed scientific journal). Physicochemical stability studies require the use of various orthogonal physicochemical methods to detect accurately the degradation changes that may result from the deamidation, oxidation, disulfide formation, aggregation or fragmentation during storage. Complementary, biological activity can be measured. Compatibility studies of Mabs and devices used for preparation and administration are still scarce. Microbiological stability of Mab preparations is related to the complexity of the preparation process, the growth supporting nature of the preparation and the integrity of the container or container/closure combination. In use viability tests revealed that the potential of Mab preparations to support microbial growth was similar to that of the pure vehicle solutions used as control solutions. The enumerated microbial counts varied according to the species utilized and the type of Mab preparation. If sterility testing of the individual preparation is impossible, maximum permitted shelf life can be assessed empirically with regard to the maximum shelf lives defined in the USP <797> monograph. Finally, microbiological and physicochemical stability are to be considered concurrently when determining the shelf life of an individual Mab preparation. In each case, shelf life should be limited according to the shorter period of proven stability, either derived from the microbiological or physicochemical stability data.

Abstract
INTRODUCTION The extended stability of the trastuzumab biosimilar Ogivri™ (MYL-1401O; trastuzumab-dkst) was studied under different storage conditions, including following reconstitution of the lyophilized powder (21 mg/mL) but undiluted and stored in vials at 4°C; after dilution at two concentrations (0.8 and 2.4 mg/mL) in polyolefin bags and stored at 4°C; and following a three-day thermal excursion to 25°C. METHODS Several methods were utilized to assess the physical and chemical stability of the drug under different storage conditions. RESULTS At all storage conditions tested, there was no change in the tertiary structure of MYL-1401O as assessed by second-derivative ultraviolet and fluorescence-derived spectral analysis, and no evidence of oligomer formation or fragmentation was observed as assessed by gel exclusion chromatography and dynamic light scattering, confirmed by assessment of quinary structures using size-exclusion chromatography. Ion-exchange chromatography showed no significant changes in the distribution of ionic variants, particularly deamidations. Thermal denaturation curves indicated no destabilization of the three-dimensional structure after 90 days at 4°C or after thermal excursion for 72 h at 25°C. CONCLUSION The trastuzumab biosimilar MYL-1401O maintained its physical and chemical stability for at least 90 days at 4°C or after thermal excursion to 25°C, supporting the safe use of MYL-1401O in several real-world settings, including advanced preparation for administration or when a break in the cold cycle occurs.

Abstract
PURPOSE Nivolumab dosage was initially selected on the basis of body weight, often resulting in leftover drug after sterile compounding. This study sought to investigate the real-world wastage of nivolumab and assess the long-term stability of leftover nivolumab within vials to facilitate drug vial optimization (DVO). METHODS We collected all discarded vials after preparation from 17 regional hospitals in Japan over a 6-month period preceding the adoption of a fixed dose of 240 mg per administration. The actual amount of waste was measured for each preparation. Stability assessment was performed under different storage conditions. RESULTS A total of 2,789 100-mg vials and 4,069 20-mg vials were collected. Overall, the drug cost associated with the expenditure of nivolumab alone was $12.1 million, whereas the total cost due to drug wastage was $0.735 million (rate of wastage, 6.1%). Furthermore, the immunoglobulin G concentrations of nivolumab remaining within vials, as well as binding activity to programmed death-1 protein, did not change significantly over 4 weeks of storage at either 4°C or room temperature. CONCLUSION Significant drug wastage occurs during sterile preparation of nivolumab according to body weight-based dosing. Although nivolumab dosing has been changed to a fixed dose in Japan, body weight-based dosing is still applied in some other countries, as well as in combination therapy with ipilimumab. Our findings regarding the long-term stability of leftover nivolumab within the vials should motivate hospitals to implement DVO for cost savings.

Physical and chemical stability of a generic etoposide formulation as an alternative to etoposide phosphate. J Pharm Biomed Anal 2020; 178:112896.

Abstract
The generic Mylan® etoposide (ETP) has been investigated as an alternative for Etopophos®, in part due to a global shortage of the latter. The generic alternative is different both in its formulation and in its very limited stability (6 h at 25 °C against 4 days for Etopophos®) once reconstituted in ready-to-use chloride or glucose solutions. Its intrinsic stability has been thoroughly studied under various conditions. Two degradation products resulting from hydrolysis were characterized by LC-HR-MSn and supported by density functional theory calculations of the frontier molecular orbitals energies, molecular electrostatic potential mapping, and Mulliken charge analysis. Chemical degradation increases with temperature and can be fitted to a zero order kinetic model with a half-life of 119 days and a kinetic constant of 0.0028 mM day-1. Precipitation was only observed in solutions at 5 °C and -20 °C indicating that at these temperatures the reconstituted solutions are thermodynamically metastable. In conclusion, ETP at concentrations of 0.68 and 1 mM prepared and stored at 25 °C under good manufacturing practices remained unchanged over a period of 21 days irrespective of the nature of the solvents or the type of container.

Abstract
Introduction Pembrolizumab is an anti-PD-1 monoclonal antibody, approved and under
development for numerous indications in oncology. It is available as either
lyophilized powder for reconstitution or ready-to-use solution. Both are
required to be diluted in saline or dextrose solution prior to intravenous
infusion. After dilution, the recommendation per summary of product
characteristics is 24 h at 2–8℃ and 6 h at room temperature. The purpose of
this study was to investigate the physicochemical stability of pembrolizumab
diluted solution (1 mg/mL) at both refrigerated and room temperature
conditions for an extended period. Methods Under aseptic conditions, pembrolizumab was diluted in 250 mL of saline
injection in polyolefin bags to obtain the final protein concentration of
1 mg/mL. Thus, prepared bags were then stored at either 5℃ ± 3℃,
refrigerator exposing the product to ambient light or room temperature
(20℃ ± 3℃) on the benchtop. Results Using several analytical methods, it was demonstrated that pembrolizumab
solution for infusion, diluted in normal saline can be stored in polyolefin
infusion bags for at least 1 week at 5℃ or RT with no evidence of chemical
or physical instability. No aggregation was observed. Conclusion Thus, the practical use of aseptically prepared diluted pembrolizumab in
saline can be safely extended to optimize the workload of centralized
preparation units and to minimize costs. However, it is the responsibility
of the end-user to maintain overall quality of prepared admixture solution
that is administered to patient, by following aseptic compounding process as
recommended in the packaging insert.

Abstract
AbstractIn hospitals, a major part of the drugs is administered via the intravenous route. When one wants to evaluate or know the stability of a drug in solution, it is necessary to know several physico-chemical parameters. Several reference works are available to help the hospital pharmacist with this research. However, reading these different sources can make you discover conflicting data. It is therefore necessary at this time to obtain the publications with contradictory results and to read them again. Seven criteria have been identified for judging the quality of a publication on physicochemical stability: full description of equipment, methods and analytical conditions of molecules studied; complete description of the procedures used to validate the analytical method; full indication of time testing and measurement bases or control; documentation on the analytical reproducibility; adequate statistical analysis; appropriate conclusions; appropriate references. In conclusion, everything in a compatibility study is important.

Abstract
Purpose: Cancer drug wastage occurs when a parenteral drug within a fixed vial is not administered fully to a patient. This study investigated the extent of drug wastage, the financial impact on the hospital budget, and the cost savings associated with current mitigation strategies. Methods: We conducted a cross-sectional study in three University of Toronto–affiliated hospitals of various sizes. We recorded the actual amount of drug wasted over a 2-week period while using current mitigation strategies. Single-dose vial cancer drugs with the highest wastage potentials were identified (14 drugs). To calculate the hypothetical drug wastage with no mitigation strategies, we determined how many vials of drugs would be needed to fill a single prescription. Results: The total drug costs over the 2 weeks ranged from $50,257 to $716,983 in the three institutions. With existing mitigation strategies, the actual drug wastage over the 2 weeks ranged from $928 to $5,472, which was approximately 1% to 2% of the total drug costs. In the hypothetical model with no mitigation strategies implemented, the projected drug cost wastage would have been $11,232 to $149,131, which accounted for 16% to 18% of the total drug costs. As a result, the potential annual savings while using current mitigation strategies range from 15% to 17%. Conclusion: The financial impact of drug wastage is substantial. Mitigation strategies lead to substantial cost savings, with the opportunity to reinvest those savings. More research is needed to determine the appropriate methods to minimize risk to patients while using the cost-saving mitigation strategies.

Abstract
The annual "LabEx MAbImprove Industrial Workshops" are primarily intended to provide a comprehensive view about topics of interest for the pharmaceutical industry to scientists involved in research on therapeutic antibodies. The third workshop in this series, held July 2, 2015 in Tours, was dedicated to the optimization of delivery, namely all processes leading monoclonal antibodies to reach their target site. The commonly used intravenous (IV) route, although advantageous in terms of pharmacokinetics and pharmacodynamics, presents some disadvantages in terms of patients' convenience, therapeutic target access or treatment cost. Such problems led pharmaceutical companies to consider more straightforward and patient-friendly administration routes, bringing the need for specific formulations adapted to the specific inherent physicochemical challenges. In this context, the workshop provided an overview of these advances and opened discussion on new administration routes and formulation development. In the first session, the opportunities and challenges of 3 main routes of administration (IV, subcutaneous (SC), and pulmonary) were discussed, integrating protein stability issues. The next session was dedicated to medical devices intended for SC and pulmonary administration. The last session focused on specific formulations for monoclonal antibodies, particularly to successfully protect antibodies upon aerosolization, to develop highly concentrated formulations for SC administration, and to use formulation as a mean to overcome the barriers to oral protein delivery. As in the previous editions, this workshop gathered people from the academic and industrial spheres and allowed rich debates and discussions.
