Pre-approval access rights to potentially life-preserving experimental treatment is the focus of Chapter 7. The chapter considers whether people with life-threatening conditions should have a right to access possibly life-saving experimental treatments, as embodied in right to try laws. It argues that, despite their significant shortcomings, right to try laws bolster disability rights by seeking to advance the right to life and survival of people with life-threatening conditions beyond medically assisted dying.
Chronic pain research studies are important for both finding new treatments and improving existing treatments for individuals with chronic pain. For clinical trials to be effective, participants need to be engaged and willing to participate in treatment groups. Our research applies the theory of planned behavior (TPB) to understand how attitudes, perceived social norms, and perceived control over intervention engagement are associated with willingness to participate in interventions for chronic low back pain (CLBP).
Methods:
Adult Michigan Medicine patients were identified using electronic medical records and emailed a link to an online, cross-sectional survey. Participants who self-reported CLBP, ability to read and write in English, and consented to participate were able to complete the survey (N = 405).
Results:
The results showed more positive attitudes, positive social norms, and higher perceived behavioral control related to specific chronic low back pain interventions are associated with greater willingness to participate after controlling for demographic and pain-related characteristics.
Conclusion:
The findings suggest that TPB constructs may be useful in guiding recruitment efforts for chronic pain intervention trials.
Interest in psilocybin as a treatment for depression has risen over the past decade, fuelled by promising clinical trials and a rapidly evolving regulatory landscape. Media coverage plays a critical role in shaping public perceptions, yet little is known about how psilocybin is portrayed in global anglophone online news for the treatment of depression.
Methods:
This study examines the comprehensiveness and sentiment of English-language online news articles (n = 125) discussing psilocybin as a treatment for depression from January 2000 to May 2024. Articles were sourced from the top 30 global anglophone news outlets, assessed using a 13-item instrument for comprehensiveness, and analysed for sentiment across five thematic categories. A separate sub-analysis was completed for Irish media.
Results:
Findings indicate a significant increase in coverage over time, with 43.2% of articles published between 2022 and 2024, predominantly from the USA (68%). While 90.4% of articles cited researchers, fewer addressed risks (47.2%), long-term evidence (46.4%), or patient perspectives (25%). Sentiment analysis revealed a very positive sentiment across articles which was 2.27 on a scale from −5 (most negative) to + 5 (most positive) (SD 1.33), with no significant changes over the time period. Reporting on psilocybin’s onset and duration of effects increased significantly, reflecting growing clinical evidence. However, coverage remains concentrated in prominent outlets, with limited attention to patient experiences and long-term safety.
Conclusions:
These findings highlight the media’s role in shaping discourse on emerging treatments and suggest a need for more balanced reporting to align public understanding with scientific evidence. This study provides a foundation for future research on media portrayals of psilocybin and implications for public perception and policy.
There are currently no disease-modifying therapies for the frontotemporal dementias (FTD), but there are ways to enhance the lives of patients and their families by targeting the symptoms and stressors that arise. Accurate diagnosis and education are important for patients and families, and safety measures are necessary to prevent harm. Advanced care planning and caregiver support are critical for a chronic disease. Non-pharmacological treatments, such as behavioral management and a multidisciplinary approach, are recommended. The pharmacotherapy options include antidepressants, antipsychotics, and other medications, but there is limited evidence to support their use. This chapter provides information on clinical trials in FTD, including patient selection and enrollment, trial design, and potential disease-modifying treatments being explored. Further research is needed to develop effective treatments for FTD.
The National Institute for Health and Care Research has enabled the integration of world-leading science with clinical practice in the UK’s National Health Service, and has saved lives and improved lives as a result. However, this integration has not extended to mental health services. The case is made for a National Institute for Mental Health Research (NIMHR) to address this inequity.
Trust in biomedical research is essential, multidimensional, and shaped by individual experiences, culture, and communication. Participants’ trust relies on researchers’ commitment to ethical practices. As public trust in science declines due to misinformation and disinformation campaigns, biomedical researchers (BmRs) must ensure trust and cultivate trustworthiness. This study explores BmR’s perspectives on trust and trustworthiness.
Methods:
We employed a qualitative, phenomenological approach to explore the experiences of BmRs. Through purposive sampling via the Indiana Clinical and Translational Sciences Institute, we invited BmRs to participate in semi-structured interviews. We employed rapid qualitative analysis (RQA) to identify key themes from interviews with BmRs. This action-oriented approach enables a research team to efficiently summarize experiences and perspectives, using structured templates and matrixes for systematic analysis and interpretation.
Results:
Fourteen BmRs were interviewed. Volunteer demographics were collected for race/ethnicity, gender, faculty rank, and investigator experience level. The following domains were identified: individual trust and trustworthiness, institutional trustworthiness, and trust and equity as a crucial part of structural and social drivers of health.
Conclusion:
We recognize that BmRs are dedicated to health equity and addressing disparities. However, in addition to committing to “best practices,” BmRs should prioritize actions that foster genuine trust from the communities they serve. More development opportunities are needed for reflection of what it means to be trusted by research volunteers and communities. Furthermore, intentions alone aren’t sufficient; earned trust and trustworthiness are vital.
The ctrdata package has been created to boost the use of data available in public registers of clinical trials. It enables user-friendly, reproducible workflows to identify trials of interest, download protocol- and results-related data, and conduct sophisticated analyses, across multiple registers and trials. ctrdata works in the widely used R environment, and its databases can be used with other tools. The package is open source with a permissive licence, to facilitate collaboration.
This report provides an overview of ctrdata, including its implementation, cases of interest to researchers in public health, medicines, and regulatory science, as well as potential limitations and further developments. At this time, ctrdata works with the European Union (EU) Clinical Trials Information System (CTIS), the EU Clinical Trials Register (EUCTR), the US Clinicaltrials.Gov (CTGOV), and the ISRCTN—the UK’s Clinical Study Registry. The registers are complementary in scope and scientific value, yet differences in data models, variable definitions, search parametrisations, and retrieval options hamper efficient scientific workflows, calling for a scientific-technical, programmatic solution and driving the development of ctrdata.
By employing ctrdata to comprehensively use and easily leverage trial register data, researchers can effectively address a variety of questions, gain useful insights into evolving policies and practices of drug development, and inform further clinical research. Patients and their organisations, developers, policymakers, and other interested parties can build on ctrdata to create solutions for their use cases.
Recently, there has been growing awareness of the so-called ‘reproducibility crisis’ which refers to the failure to replicate the findings of many scientific studies. This may arise from the employment of questionable research practices, such as ‘p-hacking’ (conducting many statistical tests, and only reporting significant results), HARKING (hypothesising after the results are known), and outcome switching (promoting secondary outcomes to primary outcomes to fit unexpected results). Open Science practices, which encourage open methodology (including pre-registration of hypotheses and outcomes), open data (in a publicly accessible repository), and open access to publication (including pre-prints), are vital to combatting these. This chapter sets out how Open Science practices can be applied to psychiatric research, including consideration of challenges which can arise, such as how to share data safely and appropriately. The chapter includes an explanation of key principles and constructs, and explains how Open Science practises can be embedded throughout the life-cycle of a project, with practical how-to guides and sign-posting to further resources.
Despite representing 18% of the world’s population and 20% of the disease burden, only an estimated 2% of global clinical trials include at least one study site in Africa. This underscores the critical need for continued research on how to overcome clinical trial challenges on the continent. In countries with established reputations for clinical trials, Contract Research Organizations (CROs) play a vital role, accounting for half of the research workforce and effectively managing clinical trials for pharmaceutical, biotechnology, and medical device companies. In contrast, the potential of CROs in Africa’s clinical trials ecosystem remains largely unexplored. This narrative review discusses the challenges, opportunities, best practices, emerging trends, and prospects of clinical trials in Africa. Major challenges in clinical trial implementation in Africa stem from gaps in financial and human resources, infrastructure, and regulatory systems, while opportunities are linked to Africa’s large population, genetic diversity, disease burden, lower operating costs, positive economic outlook, and growing interest from global health and research players. Emerging trends, such as the decentralization of clinical trials and conducting trials during public health emergencies, offer promising avenues for maintaining research continuity. Ultimately, the paper proposes a context-specific framework, aimed at maximizing the effectiveness of CROs in the continent’s clinical trials ecosystem.
Underrepresentation of people of color in clinical trials limits equity in research and treatment outcomes. This study evaluated the impact of a brief, community-focused educational intervention on perceptions and willingness to participate. Participants attended 30-minute sessions (9 virtual, 2 in-person). Identical pre- and post-surveys were analyzed using paired t-tests with Bonferroni correction. Eighty-three participants (90.5% Black, 88.4% female; mean age 46.3) showed significant improvements in comfort with participation, randomization, belief in protections, willingness to participate, and comfort in skin-related trials (all p < 0.05). Brief education may improve understanding and participation attitudes in underrepresented groups.
Historically US-based academic organizations dedicated limited resources, including policies, personnel to ensuring compliance with clinical trials registration and results reporting requirements. A recent follow-up survey finds that 6-years after an initial survey, there is increased attention and dedication of resources to improve compliance rates for clinical trials registration and results reporting.
Methods:
Internet-based online survey using Qualtrics between 20 April 2023 and 30 September 2023 distributed to Protocol Registration and Results Reporting (PRS) Administrators at US-based academic organizations with ClinicalTrials.gov organizational accounts. The survey focused on the 249 respondents of the original 2016–2017 survey published in 2018. The overall response rate was 162/249 (65.06%) with 100% participation from National Cancer Center (NCI) Designated Cancer Centers and hubs of the Clinical and Translational Science Awards (CTSA).
Results:
Results indicated a marked increase of academic organizations with policies in place for registration (43 to 74%) and results reporting (35 to 68%). The median number of Full-time Equivalent (FTE) staff at responding academic organizations increased (from 0.08 to 0.5) with statistically significant difference between the number of organizational records and FTEs supporting registration and results reporting. Larger gains are seen with NCI-Designated Cancer Centers and/or CTSA hubs.
Conclusions:
It appears academic organizations are more equipped to comply with requirements, and demonstrate a trend towards appropriate staffing. In the 6 years since the original survey, US-based academic organizations have significantly increased attention to compliance with clinical trials registration and results reporting requirements, indicated by an increase in institutional policies and dedicated personnel.
Chapter 3, “Experiments in Risk: Women and Clinical Trials,” follows feminist advocates as they set out to use the law to mandate the inclusion of women in clinical trials. With the advent of HIV treatment, people with HIV began to survive longer. A new problem emerged: Women were being excluded from clinical trials due to a 1977 Food and Drug Administration (FDA) guideline concerned about the impact of experimental drugs on women’s reproduction and the fetus. Not only did this mean that women could not access experimental treatments, it also resulted in confusion around how to treat women with HIV. Feminists began to advocate for a change in the FDA guidance which was excluding women from clinical trials. In keeping with the broader demands in the feminist movement at the time, feminists asserted that women should be able to choose to enroll in trials despite potential exposure to risks. Buoyed by ideas of choice and bodily autonomy, feminist AIDS activists were able to undo the FDA’s reticence to enroll women in clinical trials altering scientific research in HIV and beyond.
Cancer, a multifactorial and heterogeneous disease, poses a significant global health challenge. Despite current treatments such as surgery, radiotherapy, and chemotherapy, tumour recurrence and treatment side effects are common. These pitfalls necessitate a dire need for alternative therapeutic strategies with minimal side effects. This necessity has broadened the horizons of drug discovery into the marine domain, an exciting frontier for novel therapeutic agents. The marine ecosystem serves as a hub of diverse chemical groups with potential anti-cancer properties. Few marine-derived drugs are approved for cancer, and preliminary studies show that marine lead compounds can inhibit cancer cell growth and induce apoptosis. In this context, this review encapsulates an overview of ‘the current state of marine biodiscovery’. It explores the ‘potential of marine natural products in combating cancer’ with a particular focus on glioblastoma multiforme as a case study. Additionally, it discusses the ‘key strategies for advancing marine-derived anti-cancer compounds from the research stage to clinical use’. By tapping into the vast, unlocking the hidden treasures of the ocean, marine natural compounds could offer a hopeful perspective in the fight against cancer.
The unique characteristics of the cells that allow them to communicate with each other, influence their life cycle, and function by themselves have opened a magic world of precise stem cell treatment. This chapter will review the history of neural transplantation from M.L. Apuzzo’s pioneering stereotactic implantation of adrenal medulla autografts for Parkinson’s disease treatment to S. Yamanaka’s groundbreaking development of induced pluripotent stem cells. Employing cells as a therapeutic option for repairing the nervous system remains challenging. It is marked by considerations of government policy regarding embyos and fetal tissue, continuous improvement in the cell sourcing and stem cell quality, diverse expert perspectives, and the consistent upgrading of the delivery methods by experienced neurosurgeons. The authors highlight the challenges and outcomes of clinical trials for neurodegenerative diseases, stroke, and spinal cord trauma, emphasizing the safety of stem cell therapy and the limited efficacy in some cases. This chapter is a comprehensive overview of the potential and challenges of stem cell transplantation for neurological disorders, highlighting the need for further research and policy application to realize its full potential.
Sulforaphane (SFN), a bioactive compound derived from glucoraphanin in cruciferous vegetables such as broccoli, has been extensively studied for its therapeutic potential across diverse disease categories. SFN exerts its effects through well-characterised pathways, including the Keap1/Nrf2 axis, which regulates phase II detoxification enzymes, and epigenetic mechanisms such as histone deacetylase inhibition. This review evaluates clinical trials registered on ClinicalTrials.gov, focusing on those using SFN or broccoli-derived extracts.
As a result, we identified 84 trials, of which 39 have been published. Results suggest SFN’s potential in regulating redox and inflammatory pathways, improving metabolic and cardiovascular outcomes, and exerting anti-cancer and neuroprotective effects. For healthy subjects, SFN enhanced detoxification and reduced inflammation. In cancer patients, SFN showed promise in early-stage prostate and breast cancer, particularly in GSTM1-positive individuals, but had limited effects in advanced cases. For brain disorders, SFN demonstrated symptomatic improvements in autism spectrum disorder and cognitive benefits in schizophrenia but lacked robust biomarker integration. SFN had minimal impact on respiratory diseases but showed supportive roles in allergic rhinitis therapy. Metabolic disease studies revealed glycaemic control improvements in type 2 diabetes but no benefits for hypertension. Approximately 50% of completed trials remain unpublished, raising concerns about publication bias. While published results highlight SFN’s therapeutic potential, limited sample sizes and inconsistent outcomes underscore the need for more extensive, stratified trials. This review emphasises the importance of integrating mechanistic insights and precision medicine approaches to maximise SFN’s clinical utility.
Travel distance is a key barrier for patients to participate in clinical trials or receive cancer care. The National Cancer Institute (NCI) is a major funder of cancer research infrastructure through grant programs like the NCI Cancer Center (NCICC) and NCI Community Oncology Research Program (NCORP); however, the majority of US sites that care for people with cancer do not directly receive this funding.
Methods:
Through geospatial analysis we examined patient distance to NCI-funded sites and evaluated demographic subgroups to identify potential disparities in access to research opportunities. We assessed whether new NCI support to previously unfunded sites could address identified barriers in access.
Results:
NCI-funded sites tend to be in urban centers and are less accessible to low-income or rural patients. Nearly 17% of the US population over 35 years old would have to drive over 100 miles to obtain care at an NCI-funded site; only 1.6% would be beyond that distance when non-funded sites are added. For those below poverty level, the proportions are 20.2% and 1.9%, respectively. Several US regions, including the South and Appalachia, have particularly limited access to NCI-funded sites despite high cancer incidence, and much of the West and Great Plains are distant from any cancer facilities.
Conclusions:
NCI could address travel distance as a major barrier to research participation by expanding the geographical footprint of its infrastructure funding using existing institutions in areas with identified gaps. Geospatial analysis at the census tract level is recommended and geospatial visualization can help identify strategic areas for interventions.
Prospective consent in neonatal research poses significant challenges, particularly during urgent, time-sensitive clinical windows of study enrollment. This is especially true at referral centers for large geographic regions. A partial waiver of consent offers a potential translational science approach to enhance access to research participation in critically ill neonates. We compared enrollment rates in a study evaluating pulse oximetry accuracy across neonates with varying skin pigmentation before and after implementing a partial waiver of consent. Overall enrollment increased significantly without creating a racial disparity in enrollment, thereby improving generalizability and efficiency in neonatal clinical research.
Effective recruitment techniques are essential for researchers to recruit and retain potential participants in studies, particularly as recruitment numbers into clinical trials have decreased. While recruitment techniques have been investigated, there is a gap in understanding the perspectives of clinical trials recruiters. This paper examines recruiters’ usage and perceived effectiveness of various recruitment techniques, as well as their perspectives on related ethical issues.
Methods:
We conducted a cross-sectional survey of 381 clinical trials recruiters. Closed-ended items examined whether recruiters had used 31 pre-defined recruitment techniques and their perceptions of the effectiveness of each technique. For techniques perceived to be highly effective or ineffective, open-ended items examined recruiter reasoning. The multiple methods analysis integrated the closed-ended and open-ended data.
Results:
Recruitment techniques such as reassured potential participants about confidentiality (96.3%) and reassured about data sharing (95.8%) had high usage, while techniques like having the PI approach and enroll had a high average perceived effectiveness (M = 4.23, SD = 0.91). Recruiters often rated techniques as more highly effective when they had prior experience using them. They also identified concerns about professionalism, ethics, and transparency in standard practice recruitment techniques.
Conclusions:
Our findings indicate that there is significant variation in the usage of clinical trial recruitment techniques and how different recruiters view the effectiveness of each technique. The unique perspectives of those who recruit into clinical trials can help inform future decisions regarding which recruitment techniques to utilize, along with how and when to use particular recruitment techniques in an ethical manner.
Antenatal corticosteroids are given to pregnant people at risk of preterm birth to reduce newborn morbidity, including respiratory distress syndrome. However, there has been concern surrounding potential adverse effects on subsequent generations. Animal studies have demonstrated endocrine and metabolic changes in those exposed to corticosteroids in utero (F1) and in the second generation (F2). We aimed to assess the effects of parental antenatal corticosteroid exposure on health of the second generation (F2) of Auckland Steroid Trial (AST) participants. In the AST, women (F0) expected to birth between 24 and 36 weeks’ gestation were randomised to betamethasone or placebo. When their children (F1) were 50 years old, they and their children (F2) were followed up with a self-report questionnaire and data linkage. The primary outcome for this analysis was body mass index (BMI) z-score in the F2 generation. Secondary outcomes included respiratory, cardiovascular, neurodevelopmental, mental and general health, and social outcomes. Of the 213 F2 participants, 144 had BMI data available. There was no difference in BMI z-score between participants whose parent was exposed to betamethasone versus placebo (mean (SD) 0.63 (1.45), N = 77 vs 0.41 (1.28), N = 67, adjusted mean difference (95% confidence interval) = 0.16 (-0.37, 0.69)). There was no evidence of a difference in rates of overweight, diabetes, respiratory disease, cardiometabolic risk factors, neurodevelopmental difficulties, mental health difficulties and social outcomes between parental betamethasone versus placebo exposure groups, but confidence intervals were wide. These findings are reassuring regarding the intergenerational safety of antenatal corticosteroids.
