Expert Perspectives: Thromboembolic Disease in COVID-19

As part of an ongoing series of “Expert Perspectives”, Dr. Leon Henderson-MacLennan, Medical Advisor to inDemic Foundation and inThought Research, discusses the role of thromboembolic disease in COVID-19, and its implications for developmental therapeutics. Dr. Leon Henderson-MacLennan describes the rationale for conducting randomized, placebo-controlled trials on anticoagulants and anticomplement agents for COVID-19 associated thromboembolic disease, and highlights several agents and mechanisms of action to watch closely.

Clinical Trials Accrual in a Pandemic

“It was the best of times; It was the worst of times”

COVID-19 has forced a re-think of clinical trial design, enrollment, and execution. Among the challenges of clinical trial investigators are the ethical principles of compassionate (“off-label”) use of investigational therapies vs. randomized, placebo-controlled trials [1-2], as well as the logistical challenges of manufacture and distribution of investigational therapies [2].

Here, we discuss a peculiar and paradoxical challenge of clinical trials accrual in a pandemic. For any clinical trial – whether it be for cancer, Alzheimer’s disease, or diabetes – identifying and enrolling patients is a well-known challenge. For example, targeted therapies for cancers may enroll patients with rare mutations, who may be difficult to identify and to enroll onto a clinical trial at a limited number of cancer centers [3]. It is peculiar that, as millions of patients are infected by SARS-CoV-2, that there are insufficient patients for clinical trials, whose accrual goals are typically a few hundreds of patients.
