David Boulware is a professor of medicine and a practicing infectious disease physician at the University of Minnesota Medical School. He is a member of the graduate faculty for the University of Minnesota School of Public Health Epidemiology PhD program and for the Microbiology, Immunology, and Cancer Biology (MICaB) graduate program. Boulware was the first Lois & Richard King Distinguished Assistant Professorship at the University of Minnesota. Boulware is an active medical researcher engaged in clinical trials in infectious diseases. [1] His expertise is particularly in the realm of HIV-related meningitis, including Cryptococcosis and Tuberculous meningitis.
Boulware graduated from Wabash College in 1996 with a Bachelor of Arts in Chemistry. [2] He later attended the Indiana University School of Medicine, graduating in 2000. [3] He completed various residencies and fellowships from 2000-2007, receiving a certificate in tropical medicine from the Centers for Disease Control and Prevention (CDC) in 2006. He completed his master's in public health in 2007.
Boulware joined the faculty of the University of Minnesota in 2007, becoming an Assistant Professor of Medicine in the Division of Infectious Disease and International Medicine at the University of Minnesota’s Department of Medicine. Around the same time, he began working within the university’s Center for Infectious Diseases and Microbiology Translational Research (CIDMTR) to study HIV/AIDS and cryptococcal meningitis with the Infectious Diseases Institute in Uganda. [4]
He was named to the Lois and Richard King Distinguished Assistant Professorship at the school in 2011. [2]
Boulware's primary research has been focused on improving the diagnosis, prevention, and treatment of cryptococcal meningitis. [5] However, he is best known for outpatient COVID-19 clinical trials, pioneering remote de-centralized, internet-based clinical trials during the COVID-19 pandemic.
Boulware's team rapidly launched a series of three U.S. nationwide randomized clinical trials testing hydroxychloroquine for post-exposure prophylaxis, early treatment, and pre-exposure prophylaxis for prevention of COVID-19 on March 17, 2020. [6] These were among the first U.S. trials to be launched. [7] The pre-exposure prophylaxis trial was reported June 3, 2020 showing that taking hydroxychloroquine was not effective at preventing COVID-19. [8] [9] [10] As described, "To say that the recruitment of this post-exposure prophylaxis trial was innovative hardly gives the methods enough credit." [11] These trials were pioneering for being remote internet-based randomized decentralized clinical trials. [12] [13]
The hydroxychloroquine early treatment trial was the first large phase III, outpatient randomized clinical trial testing an outpatient therapy for COVID-19. [14] [15] Subsequent, meta-analysis of 11 outpatient hydroxychloroquine randomized trials of 2037 participants showed zero benefit for reducing hospitalization [16] While pre-exposure prophylaxis with hydroxychloroquine for prevention was promoted on May 18, 2020, [17] the subsequent randomized trial did not show any benefit. [18]
Describing the experimental antiviral drug remdesivir in June 2020, Boulware said that the medicine could provide "a reasonable value" if it reduced the length of stay in hospital for COVID-19 patients. [19] This true early in the pandemic waves when hospital beds were in limited supply.
Boulware served as senior investigator on other trials testing early treatments for COVID-19 including the TogetherTrial ivermectin;, [20] [21] which demonstrated that ivermectin did not have a clinical benefit for early COVID-19. [22] University of Minnesota's COVID-Out randomized trial testing metformin, ivermectin, and fluvoxamine. [23] The Covid-Out trial reported a 42% reduction in COVID-related emergency room visits and hospitalizations through 14-days with the use of metformin. [24] Metformin also had a 58% reduction in hospitalizations through 28-days and reduced long COVID by 41% through 10-months. In December 2021 at the beginning of the Omicron wave, Boulware took the initiative to apply to the U.S. FDA for an Emergency Use Authorization for fluvoxamine 100 mg twice daily. [25] This low cost generic medicine of fluvoxamine reduced covid-related hospitalizations by 25% as well as reducing ER visits and hospitalizations. [26] FDA rejected the EUA request for this low cost generic medicine questioning whether reducing prolonged ER visits and hospitalizations represents a clinically meaningful benefit. [27] Dr. Boulware has been a proponent of repurposed medicines which actually have benefit for COVID-19, including metformin, interferon-lambda, and higher-dose fluvoxamine. [28]
Boulware serves as the national co-chair of the trial steering committee for the NIH ACTIV-6 platform clinical trial testing repurposed medicines for COVID-19. [29] [30] ACTIV-6 trial has tested outpatient COVID-19 therapies including ivermectin, inhaled fluticasone, low-dose fluvoxamine 50mg twice daily, fluvoxamine 100mg twice daily, montelukast, and metformin.
Cryptococcus neoformans is an encapsulated yeast belonging to the class Tremellomycetes and an obligate aerobe that can live in both plants and animals. Its teleomorph is a filamentous fungus, formerly referred to Filobasidiella neoformans. In its yeast state, it is often found in bird excrement. Cryptococcus neoformans can cause disease in apparently immunocompetent, as well as immunocompromised, hosts.
Cryptococcosis is a potentially fatal fungal infection of mainly the lungs, presenting as a pneumonia, and brain, where it appears as a meningitis. Cough, difficulty breathing, chest pain and fever are seen when the lungs are infected. When the brain is infected, symptoms include headache, fever, neck pain, nausea and vomiting, light sensitivity and confusion or changes in behavior. It can also affect other parts of the body including skin, where it may appear as several fluid-filled nodules with dead tissue.
Post-exposure prophylaxis, also known as post-exposure prevention (PEP), is any preventive medical treatment started after exposure to a pathogen in order to prevent the infection from occurring.
Ivermectin is an antiparasitic drug. After its discovery in 1975, its first uses were in veterinary medicine to prevent and treat heartworm and acariasis. Approved for human use in 1987, it is used to treat infestations including head lice, scabies, river blindness (onchocerciasis), strongyloidiasis, trichuriasis, ascariasis and lymphatic filariasis. It works through many mechanisms to kill the targeted parasites, and can be taken by mouth, or applied to the skin for external infestations. It belongs to the avermectin family of medications.
Chloroquine is a medication primarily used to prevent and treat malaria in areas where malaria remains sensitive to its effects. Certain types of malaria, resistant strains, and complicated cases typically require different or additional medication. Chloroquine is also occasionally used for amebiasis that is occurring outside the intestines, rheumatoid arthritis, and lupus erythematosus. While it has not been formally studied in pregnancy, it appears safe. It was studied to treat COVID-19 early in the pandemic, but these studies were largely halted in the summer of 2020, and the NIH does not recommend its use for this purpose. It is taken by mouth.
Hydroxychloroquine, sold under the brand name Plaquenil among others, is a medication used to prevent and treat malaria in areas where malaria remains sensitive to chloroquine. Other uses include treatment of rheumatoid arthritis, lupus, and porphyria cutanea tarda. It is taken by mouth, often in the form of hydroxychloroquine sulfate.

Drug repositioning is the repurposing of an approved drug for the treatment of a different disease or medical condition than that for which it was originally developed. This is one line of scientific research which is being pursued to develop safe and effective COVID-19 treatments. Other research directions include the development of a COVID-19 vaccine and convalescent plasma transfusion.
COVID-19 drug development is the research process to develop preventative therapeutic prescription drugs that would alleviate the severity of coronavirus disease 2019 (COVID-19). From early 2020 through 2021, several hundred drug companies, biotechnology firms, university research groups, and health organizations were developing therapeutic candidates for COVID-19 disease in various stages of preclinical or clinical research, with 419 potential COVID-19 drugs in clinical trials, as of April 2021.
The Solidarity trial for treatments is a multinational Phase III-IV clinical trial organized by the World Health Organization (WHO) and partners to compare four untested treatments for hospitalized people with severe COVID-19 illness. The trial was announced 18 March 2020, and as of 6 August 2021, 12,000 patients in 30 countries had been recruited to participate in the trial.
Annie F. Luetkemeyer is an American physician and researcher who is Professor of Medicine and Infectious Diseases at the University of California, San Francisco. She specializes in infectious diseases, in particular tuberculosis, human immunodeficiency virus and viral hepatitis. During the COVID-19 pandemic Luetkemeyer led a clinical trial of remdesivir. She has also researched treatment of COVID-19 as a co-infection with HIV.
Jeanne Marisa Marrazzo is an American physician-scientist and infectious diseases specialist. She was the director of the University of Alabama School of Medicine Division of Infectious Diseases and focused on prevention of HIV infection using biomedical interventions. Marrazzo is a fellow of the American College of Physicians and Infectious Disease Society of America. On August 2, 2023 Lawrence A. Tabak, acting director for the National Institutes of Health (NIH), named Jeanne M. Marrazzo as director of NIH’s National Institute of Allergy and Infectious Diseases.
The treatment and management of COVID-19 combines both supportive care, which includes treatment to relieve symptoms, fluid therapy, oxygen support as needed, and a growing list of approved medications. Highly effective vaccines have reduced mortality related to SARS-CoV-2; however, for those awaiting vaccination, as well as for the estimated millions of immunocompromised persons who are unlikely to respond robustly to vaccination, treatment remains important. Some people may experience persistent symptoms or disability after recovery from the infection, known as long COVID, but there is still limited information on the best management and rehabilitation for this condition.
The Randomised Evaluation of COVID-19 Therapy is a large-enrollment clinical trial of possible treatments for people in the United Kingdom admitted to hospital with severe COVID-19 infection. The trial was later expanded to Indonesia, Nepal and Vietnam. The trial has tested ten interventions on adults: eight repurposed drugs, one newly developed drug and convalescent plasma.

Pierre Kory is an American critical care physician who gained attention during the COVID-19 pandemic for advocating widespread off-label use of certain drugs as treatments for COVID-19, as president and co-founder of the Front Line COVID-19 Critical Care Alliance (FLCCC). Kory testified twice to the U.S. Senate regarding COVID-19. During his testimony in December 2020, Kory erroneously claimed that the antiparasitic medication ivermectin was a "wonder drug" with "miraculous effectiveness" against COVID-19.
Chloroquine and hydroxychloroquine are anti-malarial medications also used against some auto-immune diseases. Chloroquine, along with hydroxychloroquine, was an early experimental treatment for COVID-19. Neither drug has been useful to prevent or treat SARS-CoV-2 infection. Administration of chloroquine or hydroxychloroquine to COVID-19 patients has been associated with increased mortality and adverse effects, such as QT prolongation. Researchers estimate that off-label use of hydroxychloroquine in hospitals during the first phase of the pandemic caused 17,000 deaths worldwide. The widespread administration of chloroquine or hydroxychloroquine, either as monotherapies or in conjunction with azithromycin, has been associated with deleterious outcomes, including QT interval prolongation. As of 2024, scientific evidence does not substantiate the efficacy of hydroxychloroquine, with or without the addition of azithromycin, in the therapeutic management of COVID-19.
