COVID-19 Pandemic and Trends in Clinical Trials: A Multi-Region and Global Perspective

Barriers to Clinical Academic Surgical Training and Career Development in the United Kingdom: A Review from the National Institute for Health and Care Research (NIHR) Advanced Surgical Technology Incubator (ASTI) Group

Clinical academics play a vital role in advancing medical research, knowledge and treatments within the National Health System (NHS), but this career's sustainability is at risk due to barriers to accessing and pursuing research opportunities throughout a surgeon's training and career. Despite the diversification of surgical training with integrated opportunities, challenges such as limited training opportunities, lack of protected research time, and financial constraints persist. This paper from the National Institute for Health and Care Research (NIHR) Advanced Surgical Technology Incubator (ASTI) group highlights these issues, addressing the competitiveness of academic pathways, workload balance, mentorship importance, and the need for standardised assessments. It highlights the need for greater accountability from healthcare employers and academic institutions. Additionally, the paper focuses on increasing diversity and inclusion in clinical academia, addressing systemic discrimination, and changing the NHS culture. This paper calls for collective efforts from the medical profession, government, and institutions to address these issues.

BMScope: A scoping review to chart the evolving clinical study landscape in brain and leptomeningeal metastasis

BACKGROUND

Recent studies have challenged the notion that patients with brain metastasis (BM) or leptomeningeal metastasis (LM) should be excluded from systemic therapy clinical trials. This scoping study summarizes the BM/LM clinical studies published between 2010 and 2023.

METHODS

MEDLINE, CINAHL, CAB Abstracts, PsycINFO, Cochrane Library, HINARI, International Pharmaceutical Abstracts, PubMed, Scopus, Web of Science, and EMBASE electronic databases were searched on June 21, 2021. An updated search was performed on February 21, 2023. Eligible studies investigated a therapeutic intervention in solid tumor patients with BM and/or LM and reported a patient outcome. Extracted study-level data, including study type, publication date, geographical location, number of BM/LM patients in the study, primary tumor type, and type of therapeutic intervention, were collected.

RESULTS

4921 unique studies were eligible for analysis. The key finding is that BM/LM clinical research is expanding globally, both in observational studies and clinical trials. Despite the shift over time toward a higher proportion of systemic therapy trials, the majority still do not include patients with symptomatic disease and lack reporting of BM/LM-specific endpoints. Globally, there has been a trend to more international collaboration in BM/LM clinical studies.

CONCLUSIONS

Our analysis of the BM/LM literature charts the evolving landscape of studies involving this previously excluded population. Given the increasing clinical research activity, particularly involving late-stage systemic therapy trials, it is imperative that due consideration is given to the intracranial activity of new investigational agents. Wider adoption of standardized reporting of intracranial-specific endpoints will facilitate the evaluation of relative intracranial efficacy.

Trends in Israeli clinical trials registration "MyTrial"

BACKGROUND

Clinical trial registration is critical for research transparency and integrity. Since 2005, the Declaration of Helsinki has required prospective registration of trials before subject recruitment. In Israel, the MyTrial registry was established in 2015 to register interventional trials and became mandatory in 2016 for ethical approval. The study aimed to analyze the registration practices, challenges, and trends in clinical trial registration in Israel using the local registry "MyTrial".

METHODS

A total of 3,895 clinical trial records from 2011 to December 2022 were retrieved from the MyTrial platform and subjected to descriptive analysis.

RESULTS

A significant increase occurred from 2016 to 2021 due to mandated registration, with a peak in 2020 (733 trials) and a decrease in 2022 (462 trials), likely due to COVID-19. Most of the trials included drugs (56%) or medical devices (33%). Geographically, 53% were from central Israel. Only 39% of the patients were registered at both MyTrial and ClinicalTrials.gov. 65% had no blinding. 47% featured unregistered products. 56% had not started recruitment. Since 2016, the number of advanced therapy trials has steadily increased, reaching 19 in 2022. There are gaps between registered trials and official government reports.

CONCLUSION

These findings provide valuable insights into the current landscape of clinical trial registration in Israel and highlight the need for improvements in compliance with prospective registration and adherence to the WHO-ICTRP standards.

Patient recruitment into clinical studies of solid malignancies during the COVID-19 pandemic in a tertiary cancer center

BACKGROUND AND PURPOSE

To analyze clinical trial activities and patient recruitment numbers into prospective clinical studies for solid malignancies during the COVID-19 pandemic in a tertiary cancer center.

MATERIALS AND METHODS

Patient recruitment numbers in prospective clinical studies of solid malignancies were retrospectively analyzed for the years 2019 - 2021 at the Comprehensive Cancer Center Zurich (CCCZ). Changes in recruitment numbers were tested for association with organ-specific subunits, as well as organizational and treatment-related trial characteristics. To assess differences between categorical variables, Chi-squared test was used. For uni- and multivariate analysis, Cox proportional hazards were calculated.

RESULTS

In 2019, there were a total of 107 studies (registry trials, clinical phase I-III trials, and translational studies) recruiting 304 patients at the CCCZ. During the COVID-19 pandemic in 2020 and 2021, there were 120 and 125 active trials with a total recruitment of 355 and 666 patients, respectively. No significant differences between the subunits and study characteristics in changes of patient recruitment in clinical phase I-III trials were identified when the year prior to the COVID-19 pandemic (2019) was compared to the first year of the pandemic (2020) and to 2020-2021.

CONCLUSIONS

Despite healthcare systems around the world have experienced significant disruption due to the COVID-19 pandemic, data from our tertiary cancer center showed that clinical trial activities were maintained at a high level during the pandemic.

Impact of the COVID-19 pandemic on the conduct of non-COVID-19 clinical trials: protocol for a scoping review

INTRODUCTION

The COVID-19 pandemic posed a detrimental impact on the conduct of non-COVID-19 related clinical trials, raising concerns about the completeness of these studies and waste of resources. While several measures and strategies have been suggested to address these issues, a thorough and timely summarisation is still lacking. Therefore, our aim is to conduct a scoping review to summarise the negative effects of COVID-19 on non-COVID-19 clinical trials, outline the effective measures for mitigating these impacts, and provide insights for future pandemics.

METHODS AND ANALYSIS

This scoping review will be conducted in line with the Joanna Briggs Institute's scoping review methodological framework, and the results will be reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews. Relevant articles will be searched in PubMed, Embase and the Cochrane Library from 1 December 2019 to 1 July 2023. We will also screen the reference lists of the included studies manually to identify more potentially relevant articles. Articles focusing on the adverse impacts of COVID-19 on non-COVID-19 clinical trials and effective measures for mitigating them will be included. Two investigators will perform study selection and data extraction independently. A narrative summary as well as a descriptive analysis of the basic characteristics and key results of the included studies will be performed.

ETHICS AND DISSEMINATION

Ethical approval is not required, as this scoping review will be completed based only on published literature. The findings of this scoping review will be disseminated through a peer-reviewed publication and/or conference presentations.

Ups and downs of conducting a national representative survey on hypertension during pandemic time: main results of SEPHAR IV

OBJECTIVES

This national representative survey sought to assess hypertension's prevalence, awareness, treatment and control in Romania.

METHODS

A representative sample (by age, sex and residence) of 1477 Romanian adults (51.19 ± 16.61 years, range 18-80 years, 59.9% women) was multimodally evaluated during two study visits. Hypertension was defined as SBP at least 140 mmHg and/or DBP at least 90 mmHg or previously diagnosed hypertension, regardless of BP. Awareness was defined by knowledge of previous hypertension diagnosis or of current use of antihypertensive treatment. Treatment was defined by antihypertensive medication taken at least 2 weeks prior to enrolment. Control was defined as SBP less than 140 mmHg and DBP less than 90 mmHg at both visits in treated hypertensive patients.

RESULTS

Hypertension prevalence was 46% ( n  = 680) consisting of 81.02% ( n  = 551) known hypertensive patients and 18.98% ( n  = 129) newly diagnosed hypertensive patients. Awareness, treatment and control of hypertension were: 81% ( n  = 551), 83.8% ( n  = 462) and 39.2% ( n  = 181).

CONCLUSION

Despite numerous pandemic-related obstacles in conducting a national survey, SEPHAR IV updates hypertension epidemiological data of a high-cardiovascular-risk Eastern-European population. This study confirms previous predictions of hypertension prevalence, treatment and control, which remain unfavourable because of unsatisfactory control of promoting factors.

Issues with Tissues: Trends in Tissue-Engineered Products in Clinical Trials in the European Union

Tissue-engineered products (TEPs) consist of engineered cells or tissues produced to regenerate, repair, or replace a dysfunctional, diseased, or absent human tissue. TEPs make up <5% of all advanced therapeutic medicinal products (ATMPs) in clinical trials and received 5.1% of ATMP-designated funding in trials in the European Union (EU) in 2019, highlighting the relatively low proportion of TEPs being developed. The realization of TEPs being marketed has yet to be fulfilled, with few products being approved. Since 2009, 90 TEP-based clinical trials have been undertaken in the EU. Of these 90, 25 were Phase I/II trials, 35 were Phase II, 28 were Phase III, and two were Phase IV trials. This review provides an overview of TEPs in development, identifying musculoskeletal, cardiovascular, and skin/connective tissue disorders as the main therapeutic areas of interest. Commercial sponsors have funded most trials, and a significantly higher proportion of late-phase trials. Furthermore, this study has identified a shift toward the use of allogeneic cells in TEPs and increased activity in the proportion of early phase trials listed. This indicates a renewed interest in TEP development as sponsors adapt to the new regulation, with prospects of more TEP market authorization applications in the future. Impact Statement Tissue-engineered products (TEPs) consist of engineered cells or tissues produced to regenerate, repair, or replace a dysfunctional, diseased, or absent human tissue. This article evaluates the regulatory landscape of TEPs and identifies the trends in clinical trial activity in the European Union (EU) since the introduction of Regulation (EC) No 1394/2007. This article identifies trends in TEP development, highlighting the most active member states, commercial involvement, a shift toward the use of allogeneic cells and a renewed interest in TEP development in recent years.

Impact of COVID-19 on Cancer-Related Care in the United States: An Overview

COVID-19 impacted several health services, including cancer-related care. Its implications were significant due to the lapse in hospital resources, compounded by the delays stemming from the economic effects on patients' jobs and medical coverage. Furthermore, reports suggesting an increased risk for morbidity and mortality from COVID-19 in patients with cancer and those on active cancer treatment caused additional fear and potential delays in seeking medical services. This review provides an overview of the pandemic's impact on cancer care in the United States and suggests measures for tackling similar situations in the future.
