Li Y, Li X, Zheng X. Effect of subcutaneous vs. intravenous tocilizumab in patients with severe COVID-19: a systematic review. Eur J Clin Pharmacol 2024:10.1007/s00228-024-03719-0. [PMID: 38926166 DOI: 10.1007/s00228-024-03719-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/15/2024] [Accepted: 06/21/2024] [Indexed: 06/28/2024]
Abstract
OBJECTIVE To systematically evaluate the efficacy of subcutaneous tocilizumab in the treatment of patients with severe COVID-19 and provide evidence for the rational use of subcutaneous tocilizumab in patients with severe COVID-19. METHODS This meta-analysis was carried out in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. We searched the Cochrane Library, PubMed, Embase, CNKI, SinoMed, and Wanfang Medical Network electronic databases up to 11 January 2023 to identify relevant studies. To obtain the most recent clinical studies of subcutaneous injection of tocilizumab for the treatment of patients with severe COVID-19, we also searched the preprint platforms medRxiv and ChinaXiv. Furthermore, we searched ClinicalTrials.gov for relevant unpublished studies. The studies were screened based on the PICOS principle. The included studies were classified and evaluated for quality based on research type. The RevMan 5.3 software was used to conduct the meta-analysis, and a descriptive analysis was performed to examine relevant outcome indicators. RESULTS Five observational studies were obtained, involving a total of 498 patients (240 patients in the subcutaneous injection group and 258 patients in the intravenous injection group). All of the studies were of the highest quality. The meta-analysis of the included studies revealed that the mortality rate of patients who received subcutaneous tocilizumab to treat COVID-19 was not significantly higher than that of the intravenous injection group [23.3% (45/193) vs. 18.4% (39/212), RD = 0.06, 95% CI = - 0.01 ~ 0.13, P = 0.11]. Furthermore, there was no significant difference in the proportion of patients requiring mechanical ventilation between the two groups [24.5% (35/143) vs. 22% (35/159), RD = 0.03, 95% CI = - 0.07 ~ 0.12, P = 0.56]. CONCLUSIONS The meta-analyses do not provide evidence that subcutaneous and intravenous tocilizumab formulations for the treatment of severe COVID-19 infection differ regarding their effectiveness. Considering that the meta-analyses cannot replace an appropriately powered non-inferiority study, subcutaneous formulations still need to be used with caution and only when intravenous formulations are in short supply. At present, there is a lack of randomized controlled trials of subcutaneous injection of tocilizumab for the treatment of severe COVID-19, and more clinical research should be conducted.

Basic regulatory science behind drug substance and drug product specifications of monoclonal antibodies and other protein therapeutics. J Pharm Anal 2024; 14:100916. [PMID: 39035218 PMCID: PMC11259812 DOI: 10.1016/j.jpha.2023.12.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2023] [Revised: 11/04/2023] [Accepted: 12/07/2023] [Indexed: 07/23/2024] Open
Abstract
In this review, we focus on providing basics and examples for each component of the protein therapeutic specifications to interested pharmacists and biopharmaceutical scientists with a goal to strengthen understanding in regulatory science and compliance. Pharmaceutical specifications comprise a list of important quality attributes for testing, references to use for test procedures, and appropriate acceptance criteria for the tests, and they are set up to ensure that when a drug product is administered to a patient, its intended therapeutic benefits and safety can be rendered appropriately. Conformance of drug substance or drug product to the specifications is achieved by testing an article according to the listed tests and analytical methods and obtaining test results that meet the acceptance criteria. Quality attributes are chosen to be tested based on their quality risk, and consideration should be given to the merit of the analytical methods which are associated with the acceptance criteria of the specifications. Acceptance criteria are set forth primarily based on efficacy and safety profiles, with an increasing attention noted for patient-centric specifications. Discussed in this work are related guidelines that support the biopharmaceutical specification setting, how to set the acceptance criteria, and examples of the quality attributes and the analytical methods from 60 articles and 23 pharmacopeial monographs. Outlooks are also explored on process analytical technologies and other orthogonal tools which are on-trend in biopharmaceutical characterization and quality control.

Abstract
Coronavirus disease 2019 is a rather heterogeneous disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The ongoing pandemic is a global threat with increasing death tolls worldwide. SARS-CoV-2 belongs to lineage B β-CoV, a subgroup of Sarbecovirus. These enveloped, large, positive-sense single-stranded RNA viruses are easily spread among individuals, mainly via the respiratory system and droplets. Although the disease has been gradually controlled in many countries, once social restrictions are relaxed the virus may rebound, leading to a more severe and uncontrollable situation again, as occurred in Shanghai, China, in 2022. The current global health threat calls for the urgent development of effective therapeutic options for the treatment and prevention of SARS-CoV-2 infection. This systematic overview of possible SARS-CoV-2 therapeutic strategies from 2019 to 2022 indicates three potential targets: virus entry, virus replication, and the immune system. The information provided in this review will aid the development of more potent and specific antiviral compounds.

Expediting the chromatographic analysis of COVID-19 antibody therapeutics with ultra-short columns, retention modeling and automated method development. J Pharm Biomed Anal 2022; 221:115039. [PMID: 36115204 PMCID: PMC9465490 DOI: 10.1016/j.jpba.2022.115039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2022] [Revised: 09/07/2022] [Accepted: 09/08/2022] [Indexed: 12/03/2022]
Abstract
The COVID-19 pandemic necessitated the emergency use authorization (EUA) of several new therapeutics and vaccines. Several monoclonal antibodies (mAbs) were among those authorized for use, and they have served a purpose to provide passive immunity and to help minimize dangerous secondary effects in at-risk and hospitalized patients infected with SARS-CoV-2. With an EUA submission, scientific data on a drug candidate is often collected near simultaneously alongside drug development. In such a situation, there is little time to allow misguided method development nor time to wait on traditional turnaround times. We have taken this dilemma as a chance to propose new means to expediting the chromatographic characterization of protein therapeutics. To this end, we have combined the use of automated, systematic modeling and ultrashort LC columns to quickly optimize high throughput RP, IEX, HILIC and SEC separations for two COVID-19-related mAbs. The development and verification of these four complementary analytical methods required only 2 days of experimental work. In the end, one chromatographic analysis can be performed with a sub-2 min run time such that it is feasible to comprehensively characterize a COVID-19 mAb cocktail by 4 different profiling techniques within a 1-hour turnaround time.

Abstract
Tocilizumab is a monoclonal antibody used in the treatment of several inflammatory and autoimmune diseases as well as cancers. Tocilizumab improves clinical outcomes and reduce mortality rates in patients with COVID-19 disease. A novel, simple and reliable method was developed to determine tocilizumab using micellar electrokinetic chromatography (MEKC). Separation of tocilizumab and the internal standard, methotrexate, was achieved with a background electrolyte consisting of phosphoric acid buffer and sodium dodecyl sulfate (SDS) with UV detection at 195 nm. The method was linear in the concentration range from 10 to 250 µg/mL with correlation coefficient greater than 0.995. The method was successfully applied to the analysis of human and rat plasma samples with good recoveries. Sample preparation involved protein precipitation followed by dilution of the supernatant. The intra‐ and inter-day precisions were less than 5%, the accuracy varied from − 2.71 to 3.84%. The proposed method has acceptable analytical performance and could be applied in future clinical and pharmacokinetic studies including anticancer therapy.

Abstract
At the beginning of the COVID-19 outbreak (end 2019 - 2020), therapeutic treatments based on approved drugs have been the fastest approaches to combat the new coronavirus pandemic. Nowadays several vaccines are available. However, the worldwide vaccination program is going to take a long time and its success will depend on the vaccine public's acceptance. Therefore, outside of vaccination, the repurposing of existing antiviral, anti-inflammatory and other types of drugs, have been considered an alternative medical strategy for the COVI-19 infection. Due to the broad clinical potential of the drugs, but also to their possible side effects, analytical methods are needed to monitor the drug concentrations in biological fluids and pharmaceutical products. This review deals with analytical methods developed in the period 2015 - July 2021 to detect potential drugs that, according to a literature survey, have been taken into consideration for the treatment of COVID-19. The drugs considered here have been selected on the basis of the number of articles published in the period January 2020-July 2021, using the combination of the keywords: COVID-19 and drugs or SARS-CoV-2 and drugs. A section is also devoted to monoclonal antibodies. Over the period considered, the analytical methods have been employed in a variety of real samples, such as body fluids (plasma, blood and urine), pharmaceutical products, environmental matrices and food.
