Liraglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist used for the management of type 2 diabetes and obesity. It was the first GLP-1 receptor agonist to be approved by the US Food and Drug Administration and the European Medicines Agency for the treatment of obesity. To date, numerous skin adverse reactions to liraglutide have been reported, but data regarding hypersensitivity reactions are scarce, raising concerns about its safety and clinical management. We present the case of a 56-year-old female patient with class 3 obesity who was started on subcutaneous liraglutide (Saxenda) by her endocrinologist. One month after starting the aforementioned treatment, the patient presented well-defined, round, erythematous pruriginous plaques surrounding the injection site, around 24 hours after the drug administration. A liraglutide-induced, delayed-type hypersensitivity reaction was suspected, which could be subsequently confirmed by allergy testing and histopathological study. This paper explores the clinical use of liraglutide, the occurrence of hypersensitivity reactions, diagnosis, management, and implications for future research. Understanding and managing liraglutide hypersensitivity is crucial to ensuring the safety and efficacy of this medication. [ABSTRACT FROM AUTHOR]

We have developed a method to determine the limit of detection (LoD) for quantitative measurement of exogenous analytes in the outer layer of the human skin by in vivo confocal Raman spectroscopy. The method is in accordance with the guidelines of the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use that have been adopted by regulatory authorities such as the American Food and Drug Administration and the European Medicines Agency. The method can be applied in silico so that the limit of detection can be assessed before starting a skin penetration study, for example, in areas of pharmaceutical formulation, pharmacokinetics, or toxicokinetics. This can significantly reduce the need for expensive and time-consuming feasibility studies. This paper describes the method to calculate this LoD as well as the experimental and methodological factors that can influence the calculation of the LoD. [ABSTRACT FROM AUTHOR]

Background: The new European Medicines Agency (EMA) Clinical Trials Information System (CTIS), based on the Clinical Trials Regulation (CTR EU 536/2014), came into full effect on 31 January 2022 and was intended to provide an easier, more streamlined approach to the registration of clinical trials taking place in Europe. Using the experience gained on the new regulatory framework from three multi-national European clinical research studies of outbreak-prone infectious diseases, this article describes the advantages and shortcomings of the new clinical trial submission procedure. Methods: We report the time to approval, size of the application dossier, and number of requests for information (RFIs) for each study. We also explore the experience of each study within the regulatory framework and its use of CTIS to document the real-world, practical consequences of the system on individual studies. The study assesses the experience of three multi-country studies conducted in Europe working within the EU and non-EU regulatory environments. Results: While the time to regulatory and ethical approval has improved since the implementation of the new regulation, the timelines for approvals are still unacceptably slow, particularly for studies being conducted in the context of an evolving outbreak. Within the new regulatory approval procedure, there is evidence of conflicting application requirements, increased document burden, barriers to submitting important modifications, and debilitating technical hurdles. Conclusions: CTIS promised to lower the administrative bar, but unfortunately this has not been achieved. There are challenges that need to be urgently confronted and addressed for international research collaborators to effectively manage health crises in the future. While the value of multi-national outbreak research is clear, the limitations and delays imposed by the system, which raise challenging ethical questions about the regulation, are prejudicial to all clinical research, especially publicly funded academic studies. This report is relevant to both regulators and clinical researchers. It is hoped that these findings can help improve pan-European clinical trials, especially for the purpose of epidemic preparedness and response. Trial registration: This paper references experiences gained during management of three pan-European trials: EU-SolidAct's Bari-SolidAct (CT No. 2022-500385-99-00 - 15 March 2022) and AXL-SolidAct (CT No. 2022-500363-12-00 - 19 April 2022), and MOSAIC (CT No. 2022-501132-42-00 - 22 June 2022).

Analytical method validation is the process of verifying a method for its purpose of fit, whether it suffices its intended application or not. Analytical method validation is a mandatory requirement to be fulfilled for measuring critical quality attributes (CQA) during the manufacturing process to get a drug approval for human, and veterinary use. As the drug approval process differs from one country to another in a similar way method validation guidelines also differ from one country to another, these requirements will be added as your country of approval differs, In the present review an attempt was made to bring all method validation guidelines in a comparative manner by comparing country-specific requirements these countries/organizations hold the major pharma market and the Stringent regularity countries. The paper majorly focuses on the analytical method used in the Biosimilar manufacturing process and its validation approach by comparing the method validation guidelines from the International Council for Harmonisation of Technical Requirements of Pharmaceuticals for Human Use (ICH), USA, European Medicines Agency (EMA), Japan and India with the CQAs monitored during the biosimilar manufacturing process.

Background: CT-P43 is a candidate ustekinumab biosimilar in clinical development. Objectives: This paper aims to demonstrate equivalent efficacy of CT-P43 to originator ustekinumab in adults with moderate to severe plaque psoriasis. Methods: This double-blind, phase III trial randomised patients (1:1) to receive subcutaneous CT-P43 or originator ustekinumab (45/90 mg for patients with baseline body weight ≤ 100 kg/> 100 kg) at week 0 and week 4 in Treatment Period I. Prior to week 16 dosing in Treatment Period II, patients receiving originator ustekinumab were re-randomised (1:1) to continue originator ustekinumab or switch to CT-P43; patients initially randomised to CT-P43 continued receiving CT-P43 (at weeks 16, 28 and 40). The primary endpoint of the trial was mean per cent improvement from baseline in Psoriasis Area Severity Index (PASI) score at week 12. Equivalence was concluded if confidence intervals (CIs) for the estimate of treatment difference were within pre-defined equivalence margins: ± 10% [90% CI; modified intent-to-treat set; Food and Drug Administration (FDA) approach] or ± 15% [95% CI; full analysis set for patients only receiving 45 mg doses in Treatment Period I; European Medicines Agency (EMA) approach]. Additional efficacy, pharmacokinetic, safety and immunogenicity endpoints were evaluated through week 52. Results to week 28 are reported here. Results: In Treatment Period I, 509 patients were randomised (CT-P43: N = 256; originator ustekinumab: N = 253). The mean per cent improvement in PASI score at week12 was 77.93% and 75.89% for CT-P43 and originator ustekinumab, respectively (FDA approach); per the EMA approach, corresponding values were 78.26% and 77.33%. Estimated treatment differences were 2.05 (90% CI −0.23, 4.32) and 0.94 (95% CI −2.29, 4.16); equivalence was achieved for both sets of assumptions. Further efficacy parameters and pharmacokinetic, safety and immunogenicity outcomes were comparable between treatment groups, including after switching from originator ustekinumab to CT-P43. Conclusions: CT-P43 demonstrated equivalent efficacy to originator ustekinumab in patients with moderate to severe plaque psoriasis, with comparable pharmacokinetic, safety and immunogenicity profiles.

Study sponsors and market authorization holders are required by the US Food and Drug Administration (FDA) and European Medicines Agency (EMA) to enroll patients administered a gene therapy product, whether in a trial setting or post‐licensure, in a long term follow‐up safety study to continue the safety assessments of their product. These follow‐up studies range between 5 and 15 years after dosing. This unprecedented duration of engagement with patients and caregivers raises logistical challenges that will require innovation and collaboration across sponsors and regulators. In this paper we delineate some of the key considerations for designing long term follow‐up protocols in the gene therapy setting, with an eye toward platform and master protocol approaches, and offer guidance for innovative operational and statistical methods that can help assess the safety profile and durability of response for these novel therapeutics.

Introduction: Today, the approval for a generic topical product includes the presentation of therapeutic equivalence to the originator based on clinical trials. To facilitate this procedure, in 2018 the European Medicines Agency (EMA) published a draft guideline on quality and equivalence of topical products, which includes request parameters regarding the quality of the newly developed generic product and test protocols for the implementation of equivalence tests regarding efficacy. Methods: To date, no data are available on the quality and evidence of the proposed test conditions. In this study, we performed an in vitro penetration test (IVPT) following the terms of the EMA draft guideline on two authorized topical products for which therapeutic equivalence was already proven during the approval process. Results: The complex biometric data processing revealed that in vitro equivalence could not be observed for all skin sections for either originator or generic product. Moreover, the necessity of the negative control proposed in the draft guideline is more than questionable. From the results presented, there were indications that a reduced number of skin donors would be sufficient to achieve statistically significant equivalence in the comparison of all applied formulations. Here, n = 7 donors was proposed instead of n ≥ 12 as the EMA draft guideline demands, decreasing the degree of biodiversity simultaneously. Moreover, a higher number of independent replicates (n > 2) was proposed for proper statistics. Conclusion: This bioequivalence study shows insufficient parameters, which should be discussed together with the EMA draft guideline. Plain Language Summary (PLS): Today in Europe the approval of generic drugs requires clinical trials to present therapeutic equivalence to the originator. To facilitate this time- and cost-intensive process, the European Medicines Agency (EMA) published a draft guideline in 2018 proposing test protocols for carrying out equivalence tests for drugs applied on human skin. Although its publication is over 5 years old, it is still in a draft version; moreover, so far no evidence has been presented on whether the experimental settings in the test protocols can prove equivalence. This study should prove the EMA test protocol for in vitro permeation tests (IVPT) as closely as possible on two authorized topical products for which therapeutic equivalence was already proven during the approval process to determine whether their equivalence could be observed by this pharmacokinetic approach as well. Due to the experimental setup, a penetration test was performed to survey the drug diffusion behavior over the skin cross section instead of the amount of drug which permeates through the skin. To the best of our knowledge, this study is the first work published regarding that topic. Here, bioequivalence of the preparations applied, which were equivalent when they were tested on patients during their approval, was not found overall. We recommend reducing the number of donors and increasing the number of replicates to achieve a higher power for the statistical data evaluation. Moreover, an evaluation of the drug amount at the pharmaceutical place of action should be considered in the EMA guideline. [ABSTRACT FROM AUTHOR]

Severe post-partum hemorrhage (PPH) is a major cause of maternal mortality worldwide. Recombinant activated factor VII (rFVIIa) has recently been approved by the European Medicines Agency for the treatment of severe PPH if uterotonics fail to achieve hemostasis. Although large randomized controlled trials are lacking, accumulated evidence from smaller studies and international registries supports the efficacy of rFVIIa alongside extended standard treatment to control severe PPH. Because rFVIIa neither substitutes the activity of a missing coagulation factor nor bypasses a coagulation defect in this population, it is not immediately evident how it exerts its beneficial effect. Here, we discuss possible mechanistic explanations for the efficacy of rFVIIa and the published evidence in patients with severe PPH. Recombinant FVIIa may not primarily increase systemic thrombin generation, but may promote local thrombin generation through binding to activated platelets at the site of vascular wall injury. This explanation may also address safety concerns that have been raised over the administration of a procoagulant molecule in a background of increased thromboembolic risk due to both pregnancy-related hemostatic changes and the hemorrhagic state. However, the available safety data for this and other indications are reassuring and the rates of thromboembolic events do not appear to be increased in women with severe PPH treated with rFVIIa. We recommend that the administration of rFVIIa be considered before dilutional coagulopathy develops and used to support the current standard treatment in certain patients with severe PPH.

Cystinosis is a rare lysosomal storage disorder caused by autosomal recessive mutations in the CTNS gene that encodes for the cystine transporter cystinosin, which is expressed on the lysosomal membrane mediating the efflux of cystine. Cysteamine bitartrate is a cystine-depleting aminothiol agent approved for the treatment of cystinosis in children and adults. In this study, we developed and validated a liquid chromatography–tandem mass spectrometry (LC-MS/MS) method for the determination of cysteamine levels in plasma samples. This LC-MS/MS method was validated according to the European Medicines Agency (EMA)'s guidelines for bioanalytical method validation. An ultra-performance liquid chromatograph (UPLC) coupled with a 6470 mass spectrometry system was used for cysteamine determination. Our validated method was applied to plasma samples from n = 8 cystinosis patients (median, interquartile range (IQR) = 20.5, 8.5–26.0 years). The samples were collected before cysteamine oral administration (pre-dose) and 1 h after (post-dose). Our bioanalytical method fulfilled the regulatory guidelines for method validation. The cysteamine plasma levels in pre-dose samples were 2.57 and 1.50–3.31 μM (median and IQR, respectively), whereas the post-dose samples reported a cysteamine median concentration of 28.00 μM (IQR: 17.60–36.61). Our method allows the rapid determination of cysteamine plasma levels. This method was successfully used in cystinosis patients and, therefore, could be a useful tool for the evaluation of therapy adherence and for future pharmacokinetic (PK) studies involving a higher number of subjects.

Eosinophilic Esophagitis is an antigen-mediated inflammatory disease characterized by thickening of the esophageal wall, leading to dysphagia, vomiting, reflux, and abdominal pain. This disease can be treated with a therapeutic approach ranging from diet to pharmacological therapy. Jorveza® (budesonide) and Dupixent® (dupilumab) are treatments for Eosinophilic Esophagitis approved by the European Medicines Agency in adults but not in children. Budesonide-based extemporaneous oral liquid suspensions could be prepared for pediatric use. The main limit of this formulation is that budesonide needs a longer residence time on the esophageal mucosa to solubilize and diffuse in it to exert its local anti-inflammatory effect. Herein, we propose the development of an extemporaneous mucoadhesive oral budesonide solution for the pediatric population. A liquid vehicle containing hydroxypropyl-beta-cyclodextrin as a complexing agent and carboxymethylcellulose sodium as a mucoadhesive excipient was used to prepare budesonide-based formulations. A stable solution at a concentration of 0.7 mg/mL was successfully prepared and characterized. The formulation showed rheological and mucoadhesive properties suitable for an Eosinophilic Esophagitis local prolonged treatment. In this way, pharmacists can prepare stable budesonide-based mucoadhesive solutions, providing both patients and physicians with a new therapeutic option for Eosinophilic Esophagitis pediatric treatment.

Targeting IL-17A using Secukinumab, a humanized monoclonal immunoglobulin G1 (IgG1)/κ against IL-17A is a therapeutic option for immune-mediated disorders such as psoriasis and ankylosing spondylitis. The US Food and Drug Administration and the European Medicines Agency have approved it for the treatment of moderate to severe plaque psoriasis, active psoriatic arthritis, ankylosing spondylitis, and non-radiographic axial spondylarthritis. Recently it has also been approved for use in children with severe plaque psoriasis, active psoriatic arthritis, and enthesitis-related arthritis. This review focuses on the role of Secukinumab in the management of children and adolescents with enthesitis-related arthritis and psoriatic arthritis. We discuss the salient findings of pivotal RCTs and other studies supporting the use of Secukinumab in adults and children, in particular, focusing on its safety and efficacy. Secukinumab is a therapeutic target for psoriasis, psoriatic arthritis, and spondyloarthropathies in both adults and children. No major safety signals are observed with its use in short-term follow-up. Thus far, Secukinumab has not been found to significantly increase the risk of tuberculosis (TB). [ABSTRACT FROM AUTHOR]

Psoriasis is a highly prevalent dermatological disease associated with an increased systemic inflammatory response. In addition, joint involvement is also present in around 20% of patients. Therefore, treatment modalities used in this condition should be simultaneously effective at improving skin manifestations, reducing inflammation, and addressing psoriatic arthritis when present. Twenty years ago, the introduction of biologic treatments for psoriasis was a turning point in the management of this condition, offering an effective and reasonably safe option for patients whose disease could not be adequately controlled with conventional therapies. At the moment, Janus Kinase inhibitors (JAKis) are a new class of promising molecules in the management of psoriasis. They are orally administered and can show benefits in patients who failed biologic therapy. We conducted a scoping review in order to identify randomized-controlled trials that investigated different JAKis in patients with plaque psoriasis and psoriatic arthritis, with an emphasis on molecules that have been approved by the European Medicines Agency and the Food and Drug Administration. The added value of this study is that it collected information about JAKis approved for two different indications, plaque psoriasis and psoriatic arthritis, in order to provide an integrated understanding of the range of effects that JAKis have on the whole spectrum of psoriasis manifestations.

Diabetes mellitus (DM) is a chronic metabolic disease affecting over 500 million people worldwide, which leads to severe complications and to millions of deaths yearly. When therapeutic goals are not reached with diet, physical activity, or non-insulin drugs, starting/adding insulin treatment is recommended by international guidelines. A novel recombinant insulin is icodec, a once-weekly insulin that successfully completed phase III trials and that has recently obtained the marketing authorization approval from the European Medicines Agency. This narrative review aims to assess icodec pharmacological and clinical features concerning evidence on benefit–risk profile, as compared to other basal insulins, addressing the potential impact on patients' unmet needs. Icodec is a full agonist, recombinant human insulin analogue characterized by an ultra-long half-life (196 h), enabling its use in once-weekly administration. Phase III randomized clinical trials involving more than 4000 diabetic patients, mostly type 2 DM, documented non-inferiority of icodec, as compared to currently available basal insulins, in terms of estimated mean reduction of glycated hemoglobin levels; a superiority of icodec, compared to control, was confirmed in insulin-naïve patients (ONWARDS 1, 3, and 5), and in patients previously treated with basal insulin (ONWARDS 2). Icodec safety profile was comparable to the currently available basal insulins. Once-weekly icodec has the potential to improve patients' adherence, thus positively influencing patients' treatment satisfaction as well as quality of life, especially in type 2 DM insulin-naïve patients. An improved adherence might positively influence glycemic target achievement, reduce overall healthcare costs and overcome some of the unmet patients' needs. Icodec has the potential to emerge as a landmark achievement in the evolution of insulin therapy, with a positive impact also for the National Health Services and the whole society.

FAF1 (FAS-associated factor 1) is involved in the activation of Fas cell surface death receptors and plays a role in apoptosis and necrosis. In patients with Parkinson's disease, FAF1 is overexpressed in dopaminergic neurons in the substantia nigra. KM-819, an FAF1 inhibitor, has shown potential for preventing dopaminergic neuronal cell death, promoting the degradation of α-synuclein and preventing its accumulation. This study aimed to develop and validate a quantitative analytical method for determining KM-819 levels in rat plasma using liquid chromatography–tandem mass spectrometry. This method was then applied to pharmacokinetic (PK) studies in rats. The metabolic stability of KM-819 was assessed in rat, dog, and human hepatocytes. In vitro metabolite identification and metabolic pathways were investigated in rat, dog, and human hepatocytes. The structural analog of KM-819, namely N-[1-(4-bromobenzyl)-3,5-dimethyl-1H-pyrazol-4-yl]-2-(phenylsulfanyl) acetamide, served as the internal standard (IS). Proteins were precipitated from plasma samples using acetonitrile. Analysis was carried out using a reverse-phase C18 column with a mobile phase consisting of 0.1% formic acid in distilled water and 0.1% formic acid in acetonitrile. The analytical method developed for KM-819 exhibited linearity within the concentration range of 0.002–10 μg/mL in rat plasma. The precision and accuracy of the intra- and inter-day measurements were <15% for the lower limit of quantification (LLOQ) and all quality control samples. KM-819 demonstrated stability under various sample storage conditions (6 h at room temperature (25 °C), four weeks at −20 °C, three freeze-thaw cycles, and pretreated samples in the autosampler). The matrix effect and dilution integrity met the criteria set by the Food and Drug Administration and the European Medicines Agency. This sensitive, rapid, and reliable analytical method was successfully applied in pharmacokinetic studies in rats. Pharmacokinetic analysis revealed the dose-independent kinetics of KM-819 at 0.5–5 mg/kg, with a moderate oral bioavailability of ~20% in rats. The metabolic stability of KM-819 was also found to be moderate in rat, dog, and human hepatocytes. Metabolite identification in rat, dog, and human hepatocytes resulted in the discovery of six, six, and eight metabolites, respectively. Glucuronidation and mono-oxidation have been proposed as the major metabolic pathways. Overall, these findings contribute to a better understanding of the pharmacokinetic characteristics of KM-819, thereby aiding future clinical studies. [ABSTRACT FROM AUTHOR]

Introduction: Over the preceding decade, an increasing number of drugs have been approved by the European Medicines Agency (EMA) with limited knowledge of their relative efficacy. This is due to the utilization of non-randomized, singlearm studies, surrogate endpoints, and shorter follow-up time. The impact of this trend on the accessibility and affordability of newly approved drugs in Europe remains uncertain. The primary objective of this study is to provide insights into the issues of accessibility and affordability of new drugs in the Norwegian healthcare system. Method: The presented study entails an analysis of all reimbursement decisions for hospital drugs in Norway spanning 2021–2022. The included drugs were approved by the EMA between 2014 and 2022, with the majority (91%) receiving approval between 2018 and 2022. The drugs were categorized based on the level of documentation of relative efficacy. Approval rates and costs (confidential netprices) were compared. Results: A total of 35% (70/199) of the reimbursement decisions were characterized by limited certainty regarding relative efficacy and as a consequence the Norwegian Health Technology Assessment (HTA) body did not present an incremental cost-effectiveness ratio (ICER) in the HTA report. Within this category, a lower percentage of drugs (47%) gained reimbursement approval compared to those with a higher certainty level, which were presented with an ICER (58%). On average, drugs with an established relative efficacy were accepted with a 4.4-fold higher cost (confidential net-prices). These trends persisted when specifically examining oncology drugs. Conclusion: Our study underscores that a substantial number of recently introduced drugs receive reimbursement regardless of the level of certainty concerning relative efficacy. However, the results suggest that payers prioritize documented over potential efficacy. Given that updated information on relative efficacy may emerge post-market access, a potential solution to address challenges related to accessibility and affordability in Europe could involve an increased adoption of market entry agreements. These agreements could allow for price adjustments after the presentation of new knowledge regarding relative efficacy, potentially resolving some of the current challenges. [ABSTRACT FROM AUTHOR]

Biosimilar insulin analogues are increasing market access for diabetic patients globally. Scientific establishment of biosimilarity is cornerstone of this key change in the medical landscape. BGL-ASP is a biosimilar insulin aspart developed by BioGenomics Limited, India. BioGenomics has considered a stepwise approach in generating the totality of evidence required to establish similarity with reference product. Insulin aspart is a recombinant rapid-acting human insulin analogue utilised in the treatment of type-1 and type-2 diabetes mellitus. The single amino acid substitution at position B28 where proline is replaced with aspartic acid results in a decreased propensity to form hexamers, thus increasing the absorption rate on subcutaneous administration compared to native insulin. In order to establish the safety and efficacy of BGL-ASP, the critical quality attributes (CQAs) of BGL-ASP are identified based on the impact created on biological activity, pharmacokinetic/pharmacodynamic (PK/PD), immunogenicity and safety. The CQAs of insulin aspart are related to product structure, purity and functionality and are characterised using a series of state-of-the-art orthogonal analytical tools. The primary protein sequence, the secondary, tertiary and quaternary structure are found to be highly similar for BGL-ASP and reference product. The product related impurities of insulin aspart and the assay content are determined using high performance liquid chromatography (HPLC) based analysis and is similar for BGL-ASP and reference insulin aspart sourced from United States of America (US), Europe Union (EU) and India. The safety, efficacy and immunogenicity of BGL-ASP is also found to be comparable with reference product and is confirmed through the clinical trials conducted as recommended by International Council for Harmonisation of Technical Requirements of Pharmaceuticals for Human Use (ICH) and European Medicines Agency (EMA) guidelines. The data encompassed in this study demonstrates that reference insulin aspart and BGL-ASP are highly similar in terms of structural, physicochemical, and biological properties, thus confirming its safety and efficacy for usage as potential alternative economical medicinal treatment for diabetes mellitus.

Background. Chimeric antigen receptor (CAR) T cell therapy, a "living drug" immunotherapy, harnesses the power of T-cells from a patient (autologous) or healthy donor (allogeneic) to target and kill cancer cells and has shown unprecedented outcomes in patients with relapsed and refractory malignancies. Treatment with CAR-T cells requires the application of unique skillsets in recognised specialist centres for successful outcomes and requires management by the multidisciplinary team incorporating the specialist pharmacist. Method. A multimodal research strategy was employed for this literature review whereby PubMed, Google Scholar, Embase, Stella Library Search, EMA website, and EBMT website were sources of information. The search was limited from 2020 onwards with key terms referring to CAR-T cell therapy. Results and Discussion. There are six CAR-T cell products currently approved by the European Medicines Agency (EMA) and Food and Drug Administration (FDA) which target haematological malignancies with abundant clinical trials underway exploring new and improved CAR designs and antigen targets. As CAR-T cell therapy is an advanced therapy medicinal product (ATMP), there is need for an extensive regulatory framework underpinning its safety and efficacy. The clinical pharmacist plays an integral role in the provision of safe and effective CAR-T cell therapy including governance, operational and clinical aspects of treatment. Pharmacists may also be involved through provision of "Qualified Person" (QP) expertise in clinical trials and for release within hospitals under certain circumstances. There is a need for harmonised and accessible guidance on the clinical delivery of ATMPs such as CAR-T cells, with fully delineated responsibilities of pharmacists involving the oversight and supervision of CAR-T cell treatment. Conclusion. There is an unmet need to provide suitable and applicable literature for clinical pharmacists who are involved in the delivery of CAR-T cells. We have provided an overview of T-cell biology and an explanation of CAR-T cell design and the biomanufacturing process. We reviewed the complex and multifaceted treatment cycle requiring considerable logistics, and described the involvement of the clinical pharmacist in each part of this cycle from patient selection to postinfusion care. Finally, we look to the challenges and future opportunities that will require the involvement of the clinical pharmacist. [ABSTRACT FROM AUTHOR]

Roflumilast, a selective phosphodiesterase 4 inhibitor, was approved by the European Medicines Agency Committee for Medicinal Products for Human Use in 2010 for the treatment of severe chronic obstructive pulmonary disease. However, low solubility of Roflumilast is a question mark to design a suitable dosage form to get therapeutic objectives. The aim of this work was to enhance solubility of the drug to develop fast release oral tablet. Drug-polymer binary system was developed at 1:1 w/w ratio followed by development of immediate release tablet by direct compression method. Drug-polymer compatibility studies were assessed by Fourier-transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, and scanning electron microscopic studies. Pre and Post- compression tests and in vitro dissolutions studies in acidic (pH 1.2) and PBS pH 6.8 were performed to evaluate in vitro performance of the developed formulations. In vitro kinetic models were applied and similarity and difference factors were computed in comparison with reference product (marketed brand). Drug content was found between 95.37 to 99.57 in the developed formulations. Drug-polymer compatibility results demonstrated good compatibility among drug, polymers and other excipients. The micromeretic parameters and post compression studies results were in acceptable limit for all the developed formulations. Fast drug release behavior was observed in acidic medium. The results suggested that similarity factor (f2) values of the developed formulations were within acceptable limit (50-100). The developed binary systems may apply to overcome solubility issues of biopharmaceutical classification system class II drugs. The developed formulations are easy to scale-up.

Background: The nonclinical as well as clinical development of orphan drugs is difficult, owing to unknown pathophysiology and the absence of animal models. Both, the U.S. Food and Drug Administration (FDA) Guidance and European Medicines Agency (EMA) Guidelines, for orphan drug development describe non-clinical studies, but lack specific information, such as animal species and study design. Against this background, this study aimed to elucidate efficient methods for evaluating nonclinical efficacy based on a review report of orphan drugs approved in Japan. Results: A total of 184 orphan drugs, including 84 anticancer and 100 non-anticancer drugs, approved in Japan from January 2010 to December 2019 were investigated. Some anticancer drugs progressed to clinical development without distinct efficacy data in nonclinical studies. Patient-derived cells have been used for some drugs due to a lack of established cell lines. Cells used for non-clinical studies were devised for drugs indicated for cancers resistant to prior therapies, tumours with specific amino acid mutations in the target molecules, and solid tumours with specific biomarkers. For some non-anticancer drugs, similar disease animal models and normal animals were used for evaluation, since animal models did not exist. Biomarkers have been used specifically for evaluation in normal animals and as endpoints in some clinical trials. Conclusions: It was possible to evaluate drug efficacy by flexibly designing nonclinical studies according to disease characteristics for potentials orphan drugs. These approaches, which are not described in detail in the EMA Guideline or FDA Guidance, may thus lead to approval. [ABSTRACT FROM AUTHOR]

Abstract Aims We have previously described the European Medicines Agency’s (EMA) and the US Food and Drug Administration’s guidelines, each for a specific psychiatric indication, on how to design pivotal drug trials used in new drug applications. Here, we report on our efforts over 3 years to retrieve conflicts of interest declarations from EMA. We wanted to assess potential internal industry influence judged as the proportion of guideline committee members with industry conflicts of interest. Methods We submitted Freedom of Information requests in February 2020 to access EMA’s lists of committee members (and their declared conflicts of interest) involved in drafting the 13 ‘Clinical efficacy and safety’ guidelines available on EMA’s website pertaining to psychiatric indications. In our request, we did not specify the exact EMA committees. Here, we describe the received documents and report the proportion of members with industry interests (i.e. defined as any financial industry relationship). It is a follow-up paper to our first report (http://doi.org/10.1017/S2045796021000147). Results After 2 years and 9 months (November 2022), the EMA sent us member lists and corresponding conflicts of interest declarations from the Committee for Medicinal Products for Human use (CHMP) from 2012, 2013 and 2017. These member lists pertained to 3 of the 13 requested guidelines (schizophrenia, depression and autism spectrum disorder). The 10 remaining guidelines were published before 2011 and EMA stated that they needed to require permission from their expert members (with unknown retrieval rate) and foresaw excessive workload and long wait. Therefore, we withdrew our request. The CHMPs from 2012, 2013 and 2017 had from 34 to 36 members; 39%–44% declared any interests and we judged 14%–18% as having industry interests. For the schizophrenia guideline, we identified two members with industry interests to companies who submitted feedback on the guideline. We did not receive declarations from the Central Nervous System (CNS) Working Party, the CHMP appointed expert group responsible for drafting and incorporating feedback into the guidelines. Conclusions After almost 3 years, we received information, which only partly addressed our request. We recommend EMA to improve transparency by publishing the author names and their corresponding conflicts of interest declarations directly in the ‘Clinical efficacy and safety’ guidelines and to not remove conflicts of interest declarations after 1 year from their website to reduce the risk of stealth corporate influence during the development of these influential guidelines.

The European Medicines Agency (EMA) has released a new guideline on the clinical investigation of antidepressants. The guideline aims to improve the efficacy, safety, and personalization of these medications. It provides information on depressive disorders, clinical trial methodology, statistical analysis, and requirements for trials in difficult-to-treat populations. The guideline also discusses the use of psychedelics in depression treatment and highlights the need for randomized, double-blind, placebo-controlled trials. The ongoing consultation process will address remaining challenges in the field. [Extracted from the article]
