Optimizing pharmaceutical management of clinical trials.

OBJECTIVES: The clinical trials pharmacists have an essential role in managing the pharmaceutical part of interventional studies. The primary objective of this article was to provide a template for improving trials management for the growing number of studies without increasing personnel resources. MATERIAL AND METHODS: A retrospective study was conducted between 2016 and 2020 at the service of pharmacy at Lausanne University Hospital in Switzerland. RESULTS: The number of clinical trials (in progress) managed at the pharmacy increased from 77 to 115 (+49%) between 2016 and 2020. The majority of these studies were in oncology and were sponsored by industry. Therefore, different changes in routine tasks were decided during the 5 years term to meet the above challenge. These modifications allowed to improve pharmaceutical and administrative management of clinical trials, without increasing personnel resources. The management template was accepted by the sponsors, and no issues were mentioned by national and international audit authorities. CONCLUSION: Changes could be made in the routine practice of the clinical trials pharmacists to improve the management of studies, while the number of trials is increasing every year.

Post-trial access to investigational drugs in India: addressing challenges in the regulatory framework.

Through the New Drugs and Clinical Trials Rules, 2019 (2019 Rules), India has developed the rules governing post-trial access (PTA) to new drugs or investigational new drugs. However, inconsistencies and interpretational challenges exist in the application of the 2019 Rules and the Indian Council of Medical Research Guidelines 2017. This conflation poses a real harm to the trial participants, specifically the ones with limited access to healthcare facilities. Since drug laws in India do not expressly deal with other forms of access like the 'Compassionate Use' or 'Expanded Access' mechanism, demarcating the scope and describing the strategies for PTA are the need of the hour. We propose possible strategies to address inadequacies in the regulatory regime and establish 'win-win' situations among all stakeholders. We further argue that India is well positioned to provide leadership by developing detailed PTA provisions and may set a potential path for the other clinical trial host countries.

Procedures for application of the extended dosing after antitumor drug clinical trials. / æŠ—è‚¿ç˜¤è¯ç‰©ä¸´åºŠè¯•éªŒå—è¯•è€ å‡ºç»„åŽå»¶ä¼¸ç»™è¯ç”³è¯·ç¨‹åº.

New drug clinical trials have been considered as a positive way for treating cancer by cancer patients and doctors, and the extended dosing is a special way for patients' withdrawal from antitumor clinical trials to obtain investigational new drugs. However, neither the regulations of expanded dosing nor the detail documents for expanded dosing have been officially published in China. At present, expanded dosing of investigational drugs is still at the exploratory stage in various medical institutions, and a complete management system has not been established to meet patients' urgent needs for drug use. Based on the practical experience of extended dosing in Hunan Cancer Hospital, this paper preliminarily explored the application procedures and ethical review requirements of extended dosing for subjects in antitumor clinical trials. It is necessary to clarify the responsibilities of all patients in the procedure and establish a patient-medical institution-sponsor joint application system. In the process of ethical review, it is recommended that all parties fully consider the risks and benefits of extended dosing for patients, and then the ethics committee makes a comprehensive assessment to decide whether to approve extended dosing.

The 'false hope' argument in discussions on expanded access to investigational drugs: a critical assessment.

When seriously ill patients reach the end of the standard treatment trajectory for their condition, they may qualify for the use of unapproved, investigational drugs regulated via expanded access programs. In medical-ethical discourse, it is often argued that expanded access to investigational drugs raises 'false hope' among patients and is therefore undesirable. We set out to investigate what is meant by the false hope argument in this discourse. In this paper, we identify and analyze five versions of the false hope argument which we call: (1) the limited chance at benefit argument, (2) the side effects outweighing benefits argument, (3) the opportunity costs argument, (4) the impossibility of making informed decisions argument, and (5) the difficulty of gaining access argument. We argue that the majority of these five versions do not provide normative ground for disqualifying patients' hopes as false. Only when hope is rooted in a mistaken belief, for example, about the likelihood of benefits or chances on medical risks, or when hope is directed at something that cannot possibly be obtained, should it be considered false. If patients are adequately informed about their odds of obtaining medical benefit, however small, and about the risks associated with an investigational treatment, it is unjustified to consider patients' hopes to be false, and hence, to deny them access to investigational drug based on that argument.

Introduction to the mini special issue on next generation drug discovery and development: rethinking translational pharmacology for accelerated drug development.

The coronavirus disease (COVID-19) pandemic further revealed the barriers to accelerated discovery and development of transformative medicines for life threatening diseases. To effectively and efficiently respond to unmet medical needs, efforts should be directed towards revolutionizing the predictive capability of non-clinical surrogates that inform drug discovery and development programs. I developed this mini special issue amidst the COVID-19 pandemic to evaluate recent advancements and opportunities for four main subthemes that support drug discovery and development including prediction of metabolic pathways, translational pharmacokinetic and pharmacodynamic studies, pharmacogenomics, and trends in bioanalysis. Scientific papers in these areas were covered by investigators from the International Society for the Study of Xenobiotics New Investigator Group and other investigators. Advancement in the predictive capability of in silico, in vitro, and in vivo models used to determine the absorption, distribution, metabolism, excretion, and toxicity profile of investigational drugs can help offset the cost of unexpected safety and/or efficacy issues during clinical studies. Likewise, extensive application of pharmacogenomics in drug development and clinical care can help direct therapeutic benefits to the appropriate patient population with the overall goal of accelerating drug development and mitigating failed drug cost. Finally, I hope that the scientific contributions in this mini special issue will stimulate practical advancements across all aspects of basic science research that support drug discovery and development to help unlock the door to the next generation of drug discovery and development that features reduced failure rates and accelerated development.

Drug cost savings in phase III hematological oncology clinical trials in a university hospital.

The rapid emergence of expensive anticancer therapies is leading to exponential growth in healthcare expenses. In clinical trials, most investigational drugs are provided free of charge by industrial and academic sponsors. This results in drug cost savings for healthcare payers, who are no longer charged with the cost of the standard-of-care treatment, which would have been administered outside the trial. This study aims to estimate drug cost savings resulting from patient enrolment in hematological oncology clinical trials, from a public payer perspective. Retrospective screening identified all patients with hematological malignancies included from 2011 to 2016 in a phase III trial and having received at least one sponsor-provided cycle. Drug cost savings were defined as the standard treatment costs not charged to the payer due to sponsor provision of treatment. For each patient, cost savings were determined by the number of cycles received in the trial and the cost of standard (control arm) treatment. Of the 345 patients included in eligible trials during study period, 272 received sponsor-provided drugs. Drug cost savings could be estimated for 177 patients (65.1%) included in 27 trials. Total cost savings were €5218 million (US$ 6804 million) for 1720 sponsor-provided cycles. Mean cost saving per patient was €19 182.7 ± 29 865.7 ($25 015.24 ± 39 478.25). Most cost-saving trials were industry-sponsored (77.8%), although academic trials generated 40.15% of total cost savings. Enrolling patients in clinical trials, whether industry-sponsored or academic, leads to substantial drug cost savings for payers. Implications are significant for public payers facing increasing financial constraints, as savings can be reallocated to patient care.

Effects of pharmacist interventions on reducing prescribing errors of investigational drugs in oncology clinical trials.

OBJECTIVES: This study aimed to investigate the effectiveness of pharmacist intervention in reducing and preventing prescribing errors of investigational drugs for cancer patients. MATERIALS AND METHODS: A retrospective study was conducted during two periods: a baseline period from December 2015 to June 2016 and an intervention period from July 2016 to February 2017. The investigational drug service (IDS) pharmacists performed active interventions during the intervention period. RESULTS: Among 12,387 investigational drug orders, 395 (6.1%) prescribing errors were detected in 6477 orders at the baseline period, and 278 errors (4.7%) were detected in 5,910 orders at the intervention period. To identify factors that affect prescribing errors, three models were constructed for the multivariate analysis. Among factors affecting prescribing errors, sponsor initiated trial (SIT) was the strongest factor (AOR: 4.16, 95% CI: 3.31-5.23). Pharmacist intervention reduced prescribing errors by at least 25% in all constructed models after adjusting for confounding variables. Prescribing errors were 1.3 times higher when dealing with intravenous medications than when dealing with oral medications. There were 60% fewer prescribing errors in the blinded study than in the open study. SIT and multi-center/multi-nation studies had 4.2 and 2.4 times more frequent prescribing errors than in investigator-initiated trials (IIT) and single-center/single-nation studies, respectively. Fewer errors occurred in phase 2 and trials covering both phase 1 and phase 2 (phase 1/2) than in phase 3 trials. CONCLUSIONS: The IDS pharmacist intervention in cancer clinical trials was associated with significant reductions in prescribing errors and may lead to increased medication safety.

Characterization of Comorbidities Limiting the Recruitment of Patients in Early Phase Clinical Trials.

BACKGROUND: Early phase clinical trials evaluate the safety and efficacy of new treatments. The exclusion/inclusion criteria in these trials are usually rigorous and may exclude many patients seen in clinical practice. Our objective was to study the comorbidities limiting the participation of patients with breast, colorectal, or lung cancer in clinical trials. MATERIALS AND METHODS: We queried ClinicalTrials.gov on December 31, 2016. We reviewed the eligibility criteria of 1,103 trials. Logistic regression analyses were completed, and exclusion was studied as a binary variable. RESULTS: Out of 1,103 trials, 70 trials (6%) excluded patients >75 years of age, and 45% made no reference to age. Eighty-six percent of trials placed restrictions on patients with history of prior malignancies. Regarding central nervous system (CNS) metastasis, 416 trials (38%) excluded all patients with CNS metastasis, and 373 (34%) only allowed asymptomatic CNS metastasis. Regarding chronic viral infections, 347 trials (31%) excluded all patients with human immunodeficiency virus, and 228 trials (21%) excluded all patients with hepatitis B or C infection. On univariate analysis, chemotherapy trials were more likely to exclude patients with CNS metastasis and history of other malignancies than targeted therapy trials. Multivariate analysis demonstrated that industry-sponsored trials had higher odds of excluding patients with compromised liver function. CONCLUSION: Many clinical trials excluded large segments of the population of patients with cancer. Frequent exclusion criteria included patients with CNS metastasis, history of prior malignancies, and chronic viral infections. The criteria for participation in some clinical trials may be overly restrictive and limit enrollment. IMPLICATIONS FOR PRACTICE: The results of this study revealed that most early phase clinic trials contain strict exclusion criteria, potentially excluding the patients who may be more likely to represent the population treated in clinical settings, leaving patients susceptible to unintended harm from inappropriate generalization of trial results. Careful liberalization of the inclusion/exclusion criteria in clinical trials will allow investigators to understand the benefits and drawbacks of the experimental drug for a broader population, and possibly improve recruitment of patients with cancer into clinical trials.

Factor XI inhibition fulfilling the optimal expectations for ideal anticoagulation.

INTRODUCTION: Thromboembolic diseases are leading cause of mortality accounting for an estimated 1 in 4 deaths all over the world. Anticoagulation remains the mainstay of prevention and treatment of venous thromboembolic disorders. Conventional anticoagulants have been efficiently used over the last decades, but their clinical use encounters safety and convenience issues. To overcome these limitations, research have focused on development of new targets for anticoagulation leading to a relatively new class of drugs, non-vitamin K antagonist oral anticoagulants, specifically targeting activated factor X and thrombin. However, the search for more potent anticoagulant agents with reduced bleeding risk is still continuing. Areas covered: In this review, we provide an overview on emerging investigational anticoagulant drugs targeting factor XI in the coagulation cascade. We review data about the role of intrinsic pathway in thrombosis and haemostasis and the rationale of different pharmacodynamic approaches targeting factor XI. Expert opinion: Recent evidence suggests that the contact pathway plays a significant role in thrombosis by thrombus stabilization and growth without perturbing haemostasis. Factor XI might be a promising drug target to develop highly effective antithrombotic therapy with safety bleeding profile. Most of these investigational agents are in early development phases, only few have reached early phase clinical trials.

Physician perspectives on compassionate use in pediatric oncology.

BACKGROUND: Targeted cancer treatments are almost always first studied in adults, even when there is a biologically plausible potential for efficacy in children. Through compassionate use programs, children who are not eligible for a clinical trial and for whom there are no known effective therapies may obtain access to investigational agents, including drugs under development for adults. However, little is known about pediatric oncologists' experiences with applying for and obtaining compassionate use agents. METHODS: This study surveyed 132 pediatric oncologists to assess awareness and utilization of compassionate use programs, to identify barriers to their use, and to evaluate available institutional support and resources. RESULTS: We found that the process of applying for access to drugs in development is poorly understood, which presents a barrier to obtaining investigational drugs. Fifty-seven percent of the pediatric oncologists applied for compassionate use. Providers from larger institutions or with more than 15 years of clinical experience were more likely to complete an application and obtain investigational agents for their patients. CONCLUSION: Identified perceived and actual barriers to compassionate use application submission suggest pediatric oncologists may benefit from educational resources and support to ensure children with cancer equal access to investigational agents and care.

Investigational drug labeling variability.

BACKGROUND/AIMS: In comparison with commercial drugs, there are few regulations concerning the labeling of investigational drugs. This leads to variability in their content and layout. This increases the risk of errors during storage, validation, compounding, dispensing and administration. The aim of this study was to evaluate the conformity and variability of investigational drug labels. Additional exploratory aims were to evaluate the use of an automated script to describe the labels and to identify the factors associated with the ease of finding a kit number. METHODS: An 87-criterion list was developed to evaluate content, format and readability. It included eight criteria to evaluate the conformity to the Canadian Food and Drugs Regulation. A systematic cross-sectional evaluation of all investigational drug labels in our 500-bed mother-child center was performed. All active protocols during the period of 14-22 February 2018 were included. Labels from drugs that were sourced locally were excluded. Labels affixed to the outside (external) and inside (internal) containers, as well as labels from American and European sponsors, were compared with the chi-square and Student's t tests. A script was developed in Python to automatically determine key information (number of words, main colors and their proportion). A short survey was conducted with a convenience sample of pharmacists to rate the ease of finding the kit number on labels. Correlation was evaluated with different factors. RESULTS: A total of 27 protocols were included (24 internal and 34 external labels). The majority (33/34) of external labels were compliant with the Regulation. Some internal labels did not state the expiry date (9/13), the sponsor address (2/13) or storing conditions (1/13). A total of 10 criteria were different between internal and external labels, for instance, the number of languages was higher on external labels (median 3 (2-14) vs 10 (2-50); p = 0.013). Five criteria were different depending on the sponsors' location, for instance, European sponsors were more prone to use bold characters (25% vs 61%, p = 0.034). There was a mean of 146 ± 111 words and 78.3% ± 7.3% empty space per label. These were positively correlated (p < 0.001). The proportion of free space on a label was also correlated with the ease of finding the kit number (p = 0.002). CONCLUSION: We measured a high variability in the labeling of investigational drugs. Key information was missing from labels affixed to internal containers, despite the use of a high number of pages. The automation worked well and further work is needed to identify criteria that may improve readability and reduce error risk. Detailed and harmonized international guidelines are needed.

What do patients with unmet medical needs want? A qualitative study of patients' views and experiences with expanded access to unapproved, investigational treatments in the Netherlands.

BACKGROUND: Patients with unmet medical needs sometimes resort to non-standard treatment options, including the use of unapproved, investigational drugs in the context of clinical trials, compassionate use or named-patient programs. The views and experiences of patients with unmet medical needs regarding unapproved, investigational drugs have not yet been examined empirically. METHODS: In this qualitative study, exploratory interviews and focus groups were held with patients with chronic or life-threatening diseases (n = 39), about topics related to non-standard treatment options, such as the search for non-standard treatment options, patients' views of the moral obligations of doctors, and the conditions under which they would or would not wish to use non-standard treatment options, including expanded access to unapproved, investigational drugs. RESULTS: Respondents had very little knowledge about and/or experience with existing opportunities for expanded access to investigational drugs, although some respondents were actively looking for non-standard treatment options. They had high expectations of their treating physicians, assuming them to be aware of non-standard treatment options, including clinical trials elsewhere and expanded access programs, and assuming that they would inform their patients about such options. Respondents carefully weighed the risks and potential benefits of pursuing expanded access, citing concerns related to the scientific evidence of the safety and efficacy of the drug, side effects, drug-drug interactions, and the maintaining of good quality of life. Respondents stressed the importance of education and assertiveness to obtain access to good-quality health care, and were willing to pay out of pocket for investigational drugs. Patients expressed concerns about equal access to new and/or non-standard treatment options. CONCLUSION: When the end of a standard treatment trajectory comes into view, patients may prefer that treating physicians discuss non-standard treatment options with them, including opportunities for expanded access to unapproved, investigational drugs. Although our respondents had varying levels of understanding of expanded access programs, they seemed capable of making well-considered choices with regard to non-standard treatment options and had realistic expectations with regard to the safety and efficacy of such options. Dutch patients might be less likely to fall prey to false hope than often presumed.

New Medications in the Treatment of Acute Migraine.

Migraine is a common disorder affecting 12% of the US population. Use of triptans results in migraine pain relief within 2 hours in 16% to 51% of patients. However, due to their vasoconstrictive properties, triptans are contraindicated in patients with cardiovascular disease, peripheral vascular disease, cerebrovascular disease, and uncontrolled hypertension because of the potential for ischemia. This article will review 2 new classes of drugs being developed for the treatment of acute migraine without vasoconstrictive effects.

Molecular mechanisms and therapeutic targets in neuroblastoma.

Neuroblastoma is the most common extracranical tumor of childhood and the most deadly tumor of infancy. It is characterized by early age onset and high frequencies of metastatic disease but also the capacity to spontaneously regress. Despite intensive therapy, the survival for patients with high-risk neuroblastoma and those with recurrent or relapsed disease is low. Hence, there is an urgent need to develop new therapies for these patient groups. The molecular pathogenesis based on high-throughput omics technologies of neuroblastoma is beginning to be resolved which have given the opportunity to develop personalized therapies for high-risk patients. Here we discuss the potential of developing targeted therapies against aberrantly expressed molecules detected in sub-populations of neuroblastoma patients and how these selected targets can be drugged in order to overcome treatment resistance, improve survival and quality of life for these patients and also the possibilities to transfer preclinical research into clinical testing.

RxLegal: A Rapid Review of Right-To-Try.

Right-to-try legislation is intended to allow patients with life-threatening illnesses access to investigational medical treatments without formal Food and Drug Administration (FDA) involvement. Currently, right-to-try laws have been enacted in 40 states. Despite the increased passage of right-to-try legislation at the state level, individuals have detailed arguments both for and against these laws. Proponents state that right-to-try removes regulatory burdens and improves timely access to potentially lifesaving medications for terminally ill patients, reduces inequalities regarding access, and improves patient-provider communication and decision making. Opponents argue that right-to-try does not really guarantee access, reinforces preexisting health care inequalities, prioritizes rapid access over safety and the interests of the individual over the public, and produces concerns regarding informed consent. Despite these issues, right-to-try has recently gained traction on the federal level with both Congressional chambers passing separate bills.

New Medications in the Treatment of Acute Decompensated Heart Failure.

Acute decompensated heart failure is a sudden worsening of heart failure symptoms, typically resulting in peripheral edema and dyspnea as a result of pulmonary congestion. Acute decompensated heart failure is responsible for over 1 million hospitalizations every year. Current pharmacologic therapy is limited in its options. Despite an improved survival rate, statistic still suggests that about 50% of patients die within 5 years of diagnosis. New pharmacologic agents aim to improve efficacy by targeting previously unexplored physiological pathways.

New Medications in the Treatment of Hereditary Transthyretin Amyloidosis.

Hereditary transthyretin amyloidosis is an inherited disorder that results in the gradual progressive deposit of abnormal protein called amyloid in the body's organs and tissues. There are currently no approved drugs to treat transthyretin amyloidosis, and patients may require liver transplantation for survival. There are a few drugs in development to treat hereditary transthyretin amyloidosis either by stabilizing the abnormal protein or by decreasing production of transthyretin. Both methods are being developed to slow progression of the disease.

Antibiotics in Development for the Treatment of Resistant Bacterial Disease.

Many bacterial infections can be treated with the use of antibiotics. These medications continue to reduce morbidity and mortality; unfortunately, their use has brought about drug-resistant pathogens that produce difficult-to-treat infections, which require more extreme treatments. New antibiotics are needed to combat this ever-evolving resistance pathogenesis.

New Medications in the Treatment of Peanut Allergy.

In the general population, the prevalence of peanut allergy has remained stable at 1.3%. However, in children, the prevalence appears to be increasing. There are no approved treatments for peanut allergy so current treatment involves educating the patient on avoiding products that contain peanut protein. Two drugs that allow controlled desensitization with controlled amounts of peanut protein have reached late stages of development.

BACE Inhibitors and Tau Protein Targeting Drugs in Prevention of Alzheimer's Disease.

Alzheimer's disease (AD) is a common disease in the United States with almost 10% of people older than 65 suffering from the disease. A few drugs provide some improvement in mental function in mild-to-moderate disease, but no treatments are available to prevent the development of AD. Two new classes of drugs being investigated for the treatment or prevention of AD include drugs to decrease beta amyloid accumulation and Tau protein aggregation inhibitors. After disappointing results for treatment of AD, both classes are being tested in prevention trials.
