A Test of Autonomy Restoration Postscripts to Mitigate Psychological Reactance to an Opt-Out Organ Donor Registry in the United States.

The organ shortage continues to present problems around the world including the United States. In response, some countries have switched from an opt-in organ donor registry to an opt-out registry. The United States currently utilizes an opt-in registry where an individual is not considered an organ donor until they register their intentions.

Application of exposure bracketing to streamline the development of contraceptive products.

Developing new long-acting products of well-characterized contraceptive drugs is one way to address some of the reasons for unmet need for modern methods of family planning among women in low- and middle-income countries. Development and approval of such products traditionally follow a conventional paradigm that includes large Phase 3 clinical trials to evaluate efficacy (pregnancy prevention) and safety of the investigational product. Exposure-bracketing is a concept that applies known pharmacokinetics and pharmacodynamics of a drug substance to inform its safe and efficacious use in humans.

Eight years of the East African Community Medicines Regulatory Harmonization initiative: Implementation, progress, and lessons learned.

Jane H. Mashingia and colleagues reveal the progress made to date for the East African Community Medicines Regulatory Harmonization initiative.

Scientific considerations for global drug development.

Requiring regional or in-country confirmatory clinical trials before approval of drugs already approved elsewhere delays access to medicines in low- and middle-income countries and raises drug costs. Here, we discuss the scientific and technological advances that may reduce the need for in-country or in-region clinical trials for drugs approved in other countries and limitations of these advances that could necessitate in-region clinical studies.

Clinical trials in the pandemic age: What is fit for purpose?

It is critical to ensure that COVID-19 studies provide clear and timely answers to the scientific questions that will guide us to scalable solutions for all global regions. Significant challenges in operationalizing trials include public policies for managing the pandemic, public health and clinical capacity, travel and migration, and availability of tests and infrastructure. These factors lead to spikes and troughs in patient count by location, disrupting the ability to predict when or if a trial will reach recruitment goals.

Time to Step Up: A Call to Action For the Clinical and Quantitative Pharmacology Community to Accelerate Therapeutics for COVID-19.

The global response to finding therapeutics for coronavirus disease 2019 (COVID-19) is chaotic even if well intentioned. There is an opportunity, but more importantly, an obligation for the global clinical and quantitative pharmacology community to come together and use our state-of-the-art tools and expertise to help society accelerate therapeutics to fight COVID-19. This brief commentary is a call to action and highlights how the global pharmacology community should contribute to the COVID-19 pandemic and prepare for future pandemics.

Drug-Drug Interactions of Infectious Disease Treatments in Low-Income Countries: A Neglected Topic?

Despite recent advances in recognizing and reducing the risk of drug-drug interactions (DDIs) in developed countries, there are still significant challenges in managing DDIs in low-income countries (LICs) worldwide. In the treatment of major infectious diseases in these regions, multiple factors contribute to ineffective management of DDIs that lead to loss of efficacy or increased risk of adverse events to patients. Some of these difficulties, however, can be overcome.

Poor medication adherence in clinical trials: consequences and solutions.

Poor adherence to medicines in clinical trials can undermine the value of the trials; for example, by compromising estimates of the benefits and risks of a medicine. In this article, we highlight such consequences and also discuss approaches to tackle this problem.

Speeding Access to Vaccines and Medicines in Low- and Middle-Income Countries: A Case for Change and a Framework for Optimized Product Market Authorization.

Background: The United Nations Millennium Development Goals galvanized global efforts to alleviate suffering of the world's poorest people through unprecedented public-private partnerships. Donor aid agencies have demonstrably saved millions of lives that might otherwise have been lost to disease through increased access to quality-assured vaccines and medicines. Yet, the introduction of these health interventions in low- and middle-income countries (LMICs) continues to face a time lag due to factors which remain poorly understood.

DG-041 inhibits the EP3 prostanoid receptor--a new target for inhibition of platelet function in atherothrombotic disease.

Receptors for prostanoids on platelets include the EP3 receptor for which the natural agonist is the inflammatory mediator prostaglandin E(2) (PGE(2)) produced in atherosclerotic plaques. EP3 is implicated in atherothrombosis and an EP3 antagonist might provide atherosclerotic lesion-specific antithrombotic therapy. DG-041 (2,3-dichlorothiophene-5-sulfonic acid, 3-[1-(2,4-dichlorobenzyl)-5-fluoro-3-methyl-1H-indol-7-yl]acryloylamide) is a direct-acting EP3 antagonist currently being evaluated in Phase 2 clinical trials.
