ABSTRACT

Drug development is a process that demands huge investment of resources and time with only 1 drug candidate successful in reaching market among 10,000 screened taking time duration of 10-15 years and millions of dollars. This high attrition rates discourage investors and researchers. The pharmaceutical industry is shifting its attention away from de novo drug research and towards discovering novel targets and indications for already-approved drugs. In order to accelerate the drug development process with reduced risk of failure and relatively lower costs, pharmaceutical companies have adopted drug repositioning as an alternative. Therefore, a good strategy for drug development would be drug repositioning or drug repurposing, which is to identify, investigate, and exploit new therapeutic uses of already-available, on-market drugs, as well as those that have been withdrawn due to toxicities or that remain on shelves in various stages of development. The outbreak of SARS-COV-19 shows that humanity is constantly vulnerable to epidemics and new microbial attacks and that there is no time to create disease-specific therapies. Consequently, it would seem advantageous to use what is already accessible. Novel therapeutic indications that have previously been approved by the market can reduce investment costs significantly in terms of money, resources, and most importantly, time, as long as they meet PKPD and toxicity standards. Sponsors and pharmaceutical corporations get enthusiastic about additional investments and initiatives related to drug development as a consequence. The upcoming therapeutic revolution, especially with the aid of artificial intelligence, is indicated by the successful applications of several already-available drugs against COVID-19 and the various phases of repurposed drugs against TB, colorectal cancer, Alzheimer抯 disease, cervical cancer, and Parkinsonism.

ABSTRACT

Quality by Design, Dr. Joseph M. Juran first introduced this concept in the 1970s., represents a risk-based approach to drug development, emphasizing continuous risk management throughout a product's lifecycle and predefined objectives. Implementation guidelines are detailed in the International Council of Harmonization (ICH) standards Q8–11. About a decade ago, the European Medicines Agency (EMA) adopted QbD principles for the pharmaceutical regulatory framework in the European Union. Despite recognition as essential in 2014, the integration of QbD into European marketing authorization applications remains limited and is not standardized. Using information from EPARs, a recent four-year study (2020–2023) aimed to evaluate how QbD principles were applied in all EU-approved marketing applications. Approximately 33.13% (111) out of 335 pharmaceuticals were developed using quality by design (QbD) principles, and 37.01% of all permitted drugs (77 out of 208 under article 8(3)) used QbD. Remarkably, over the course of four years, 30–40% of approved items that were presented as stand-alone documents adopted QbD. Most approved fixed-dose combination medications (71% in 2020 and 100% from 2021 to 2023) were, interestingly, developed utilizing a QbD strategy. Furthermore, four applications for market authorization incorporating QbD principles in the dossier were denied by the EMA. In conclusion, according to EPARs, regulatory dossiers lack complete QbD implementation, but the modest use of QbD components suggests a growing interest among businesses, potentially indicating a shift towards accepted development standards. Effective communication between regulatory bodies and companies is crucial for addressing challenges in QbD application.

ABSTRACT

Since the beginning of the 21st century, the field of cancer drug development has undergone significant changes. Kinase inhibitors are the product category with the highest number of approved drugs and indications. However, despite checkpoint inhibitors being only introduced to the market since 2011, they have become the second most approved product categories. In the year of 2023, the FDA’s Center for Drug Evaluation and Research (CDER) has approved 13 new cancer therapeutic drugs. In the past five years, a slight increase in drug approvals targeting biomarker-defined populations as well as emerging approvals that are agnostic to tumor anatomy has been recorded. Currently, new treatment approaches and technologies, such as the development of Artificial Intelligence (AI), have increasingly profound progress on cancer drug development.

ABSTRACT

Abstract Experimental research with the use of animal models to represent a specific reality is a target of criticism by the population. This study analyzed the knowledge of elementary and high school students on experimental/animal research methods, official ethical guidelines/laws, and regulatory institutions. In total, 35 students answered an informative questionnaire with objective questions about the subject. Only 18 students (Group 1), attended a lecture on the subject. The questionnaire was reapplied to all 35 students. The analysis of the first questionnaire round showed rejection by 51.4% of the students toward the methods used in experimental research. Significant changes in answer patterns between the first and second evaluations were observed, with a decrease in the number of students who strongly disagree with the methods used in experimental research in Group 1 (38.8%) compared to Group 2 (88.2%). These data suggest that educational activities could increase the acceptance of experimental research by the community.

ABSTRACT

Abstract In the last few decades, there have been considerable improvements in the diagnosis and care of Duchenne muscular dystrophy (DMD), the most common childhood muscular dystrophy. International guidelines have been published and recently reviewed. A group of Brazilian experts has developed a standard of care based on a literature review with evidence-based graded recommendations in a two-part publication. Implementing best practice management has helped change the natural history of this chronic progressive disorder, in which the life expectancy for children of the male sex in the past used to be very limited. Since the previous publication, diagnosis, steroid treatment, rehabilitation, and systemic care have gained more significant insights with new original work in certain fields. Furthermore, the development of new drugs is ongoing, and some interventions have been approved for use in certain countries. Therefore, we have identified the need to review the previous care recommendations for Brazilian patients with DMD. Our objective was to create an evidence-based document that is an update on our previous consensus on those topics.


Resumo Nas últimas décadas, houve progressos significativos no diagnóstico e no tratamento da distrofia muscular de Duchenne (DMD), considerada a distrofia muscular mais comum na infância. Diretrizes internacionais foram publicadas e revisadas recentemente. Um grupo de especialistas brasileiros desenvolveu um padrão de atendimento baseado em revisão de literatura, com recomendações graduadas pautadas em evidências compiladas em uma publicação dividida em duas partes. A implementação de melhores práticas de manejo ajudou a modificar a história natural desta doença crônica, progressiva, que, no passado, oferecia uma expectativa de vida muito limitada para crianças do sexo masculino. Desde a publicação desse consenso anterior, o diagnóstico, o tratamento com esteroides, a reabilitação e os cuidados sistêmicos ganharam novas possibilidades a partir da divulgação dos resultados de trabalhos originais em algumas dessas áreas. Além disso, as pesquisas e o desenvolvimento de novos fármacos estão em andamento, e algumas intervenções já foram aprovadas para uso em determinados países. Nesse contexto, identificamos a necessidade de rever as recomendações anteriores sobre o manejo dos pacientes brasileiros com DMD. Nosso objetivo principal foi elaborar uma atualização baseada em evidências sobre esses tópicos do consenso.

ABSTRACT

Evolution and natural selection have endowed animal venoms, including scorpion venoms, with a wide range of pharmacological properties. Consequently, scorpions, their venoms, and/or their body parts have been used since time immemorial in traditional medicines, especially in Africa and Asia. With respect to their pharmacological potential, bioactive peptides from scorpion venoms have become an important source of scientific research. With the rapid increase in the characterization of various components from scorpion venoms, a large number of peptides are identified with an aim of combating a myriad of emerging global health problems. Moreover, some scorpion venom-derived peptides have been established as potential scaffolds helpful for drug development. In this review, we summarize the promising scorpion venoms-derived peptides as drug candidates. Accordingly, we highlight the data and knowledge needed for continuous characterization and development of additional natural peptides from scorpion venoms, as potential drugs that can treat related diseases.

ABSTRACT

Model-informed drug develop-ment(MIDD)is the application of a various math-ematical,statistical,and biological models to facilitate drug development,decision making and regulatory review.As a quantitative tool,MIDD approaches allow an integration of information obtained from non-clinical studies and clinical trials in a drug development program.General understandings of the underlying biology,patho-physiology,and pharmacology can also be incor-porated into the model.MIDD is centered on knowledge and inferences generated from inte-grated models of the physicochemical character-istics of a molecule,its disposition in the body,and its mechanism of action,and how the drug might affect a disease from both an efficacy and a safety perspective.MIDD approaches have the potential to significantly streamline drug develop-ment,by improving clinical trial efficiency,opti-mizing dose and regimen and waive unneces-sary clinical studies.This presentation will use cases studies to demonstrate how to apply MIDD in early phase of clinical trials.

ABSTRACT

Quantitative systems pharmacology (QSP) modeling is an emerging computational medicine approach with growing applications and significance in modern drug development. QSP models are generally formulated based on multiscale disease mechanisms and drug-target interactions, which makes them capable of integrating multimodal data from the preclinical and clinical space. This also enables them to generate quantitative characterization of the dynamic disease progression as well as high-throughput predictions of drug-induced efficacy and toxicity signals. Therefore, QSP modeling and model-based virtual clinical trials have been widely implemented to guide drug development, in scenarios such as target identification and assessment, clinical trial design, evaluation of combination therapy and biomarkers, and personalized medicine. In US and Europe, QSP modeling has been developing rapidly in the past 10 years and is now an integral part of the model-informed drug development paradigm; however, in China it is still a nascent field. Here we will present a comprehensive review of the recent advancements of QSP and its impact in modern drug development through a number of case studies. This review will provide guidance for the future drug development efforts and the growth of QSP practice in China.

ABSTRACT

ABSTRACT There is a consensus that the antifungal repertoire for the treatment of cryptococcal infections is limited. Standard treatment involves the administration of an antifungal drug derived from natural sources (i.e., amphotericin B) and two other drugs developed synthetically (i.e., flucytosine and fluconazole). Despite treatment, the mortality rates associated with fungal cryptococcosis are high. Amphotericin B and flucytosine are toxic, require intravenous administration, and are usually unavailable in low-income countries because of their high cost. However, fluconazole is cost-effective, widely available, and harmless with regard to its side effects. However, fluconazole is a fungistatic agent that has contributed considerably to the increase in fungal resistance and frequent relapses in patients with cryptococcal meningitis. Therefore, there is an unquestionable need to identify new alternatives or adjuvants to conventional drugs for the treatment of cryptococcosis. A potential antifungal agent should be able to kill cryptococci and "bypass" the virulence mechanism of the yeast. Furthermore, it should have fungicidal action, low toxicity, high selectivity, easily penetrate the central nervous system, and widely available. In this review, we describe cryptococcosis, its conventional therapy, and failures arising from the use of drugs traditionally considered to be the reference standard. Additionally, we present the approaches used for the discovery of new drugs to counteract cryptococcosis, ranging from the conventional screening of natural products to the inclusion of structural modifications to optimize anticryptococcal activity, as well as drug repositioning and combined therapies.

ABSTRACT

Abstract Biological activity of boron-containing compounds (BCCs) has been well-known. Growing interest and numerous applications for BCCs have been reported. Boron and boron-containing acids show low acute toxicity in mammals but data on halogenated boroxine (HB) - dipotassium-trioxohydroxytetrafluorotriborate, K2(B3O3F4OH) acute toxicity have not been reported before. This compound, characterized as a potential therapeutic for skin changes, exhibits no observable genotoxicity in doses lower that 0.1 mg/ml in vitro and 55 mg/kg in vivo. It has also been confirmed as an antitumour agent both in vitro and in vivo as well as an inhibitor of enzymes involved in antioxidant mechanisms. The aim of this study was to assess the acute toxicity of HB and to determine the maximum tolerated dose as well as a dose free of any signs of toxicity in different test organisms. Acute toxicity of HB was tested in Sprague-Dawley and Wistar rats and BALB/c mice after single parenteral application of different doses. We determined doses free of any sign of toxicity and LD50 after single dose administration. LD50 of HB ranges from 63 to 75 mg/kg in different test models, meaning that HB shows moderate toxicity

ABSTRACT

As the incidence of male infertility has been increasing during recent years, it is urgent to reveal the pathogenesis of male infertility, as well as to develop the new drugs for treatment of male infertility, in order to solve the declining birth rate and aging problems. The construction and application of male infertile animal models is critical for drug development, which plays an important role in accurately evaluating the efficacy and mechanism of infertility treatment. A suitable infertility model not only can reduce the repeated drug efficacy evaluations, reduce animal usage and the cost of new drug development, but also has important reference value for subsequent clinical trial research. Male infertility laboratory animal models can be constructed through chemical, physical, endocrine, environmental estrogen, gene modification, and immune methods. This article mainly introduces the existing male infertility animal models available for drug development, and briefly introduces the application progress of each model to provide reference for the male infertility drug researchers.
